Notice of Construction History In October 1997, a short form Notice of Construction (NOC) for w·aste Encapsulation and Storage Facility (WESF) Tank 100 Activities to Support Low Level Liquid Wasie Decoupling was presented to and approved by the Washington Department of Health (WDOH) at a Routine Technical Exchange Meeting (RTEM). U.S. Environmental Protection Agency (EPA) provided final approval on May 11, 1998. cin December 17, 1997, a NOC for the K-3 Duct Characterization was presented to and approved by WDOH during a RTEM. On Feliruary 26, 1998, a short form NOC for Liquid Lciw Level Radioactive Stearn Piping Modification and Contingency Operations was presented to and approved by WDOH d_uri.ng a RTEM_. On. N.overnber 23, 1999, a short form NOC for Re:<:ord Sample Prob¢ hivestigation and Repair was presented to and approved by WDOH during·a RTEM. On May 19, 1999, WDOH approved

. th¢ alternat_ive stack lll<Jn_i_toring method and upgracled the stack to a rnajor stac_k (AIR 99-501, "Apprcival of 296°B-IOStack Upgrade from a Minor to a Major Stack") .. EPA approved the alternative stack monitoring method on August 12, 1999.

The high-effi_ciency particulate air (HEPA) fiiters located in the K3 exhailst filter housings are riiore than 22 years old and have surpassed.their projected life-expectancy. The K3 HEPA exhaust filter housings are loc_at.ed i.n an underground vault (225BB building) and are not readi_ly a_ccessible. Th.ere is legacy contamination in Hot Cells A.through F, the K3 ductwork, and on the K3 filters that may have a negative effect if not contained or sta),ilized. ·these conditions support tp_e need for a safe and cost-effective approach to stabilize contamination.and replace in kind the K3 exhaust system (CHPRC-02388, Final Design Report W-1'30 WESF Stabilization and Ventilation Project[W-130 Project]).

This NOC Applicat_i_on (NOCA) is provided to support the W-130 Project, which incl_ud.es.the iristallati_on of an in-kind replacement exhaust system (the K3N system replaces the existing K3 exhaust system) and stabilization of contamination in portions of the facility. The new exhaust syst_e'lll consists of ducting ancl supports, an in-line heater, two stages of HEPA filtration,.redundant fans, and a control system. The project installs a new skid-mou~ted ION system to replace the existing K_3 exhaust syst.ern to ai!ow for the stabilization of contamination (by placing grout) in facility rooms and cells, in the existing K3 ductwork, and in the K3 filter housing. The K3N ventilation skid will be located outdoors adjacent to the WES_F Truck Port (located in the southwest corner of the 225B Building). It will tie irito existing ducting upstream of the existing K3 filters and will exhaust through the existing WESF stack.

Stabilization entails the core drilling-of penetrations into the hot pipe trench, the K3 duct trench, K3 HEPA filter housing, and the K3 filter pit for placement ofgrolit. Design attributes and details of the K3N ventilation skid and necessary modifications to the facility to support stabilization activities of the legacy contamination can be found in Sections 4.0 a11d 5.0 of CtiPRC-02388.

3 Proposed Action

/

221

Regulatory Requireiltent: Identify the type of proposed action for which this application is submitted:

The proposed action for this NOCA is to modify (replace in-kind [WAC 246-247--030 (22)],) the existing K3 abatement system prior to stabilization of cont_arninaJ_ion i_n the K3 dilc_t, tl)e K3 HEPA filter housing, the K3 filter pit, Hot Cells A through F, the hot pipe trench and the K3 duct trench. The proposed action also incl_udes fa<ei_lity op<;rat_io_11s after the concJ_usiol_l of the st_a~i_ii_,:ation_ llf_t_ivities. Pel\etrat_\ons \llto th_e hot pipe trench and K3 duct trench underneath the hot cells will be made by core drilling through existing

\ \

2


concrete to. allow grout to be placed into these areas. The K3 HEPA filter housings and K3 filter pit will also be core drilled to allow for grout placement

The proposed actions will require four diff~rel!ct operating configurations for temporary porta_ble exhausters, Kl, K3, and K3N abatement systems:

1. Phase I - During the preparatory work to install the K3N abatement system, both the Kl and K3 abatem"n.t systems w{il b"~ in operation with th_e·conmion stac.k emission monitoring system operating as described in Section 9.

2. Phase 2 -The mechanical tie~in ofthe K3N system into the K3 exhaust duct system will require both t_he iq and IQ abate_rn_el)t systems .to be sh):it down_. The ducting will be modified to exha_ust the Can you and remaining Hot Cell (i through the new (K3N} abatement system. During the tie-in, portable exhausters will be u.sed to maintain a n_egative differential pressure in th_e Hot Cells _and K3 exhaust duclto prevent the spread of contamination.beyond those areas. Temporary containment enclosures with HEPA filtration will be uuiized for ciiscoi:i.necting the fans and ciuct_i_ng from the K3 filter pit as required by the Radiation Control organization as low as reasonably achievable (ALARA) processes. There will be no active ventilation (supply or·exhaust) at the fadiity or stack emission m,:mi_toring during the K3N tie-in. To allow for the diffusion of any hydrogen or heat buildup in the pool area (Kl), .a building penetration will be kept open to the outside atmosphere during this.period of time .. The emission monitoring for these activities is describe_d in Section 9.

3. Phase 3 -After completion of the duct tie-in and startup of the K3N abatement system, the K 1 abatement system will return to operation prior to the ,start of stabilization (grouting) activities. The common stack emissi_ori mo"nitoring system will be in operation as described in Section 9. Temporary containment enclosures equipped with portable HEPA exhausters will be used when core drifi{ng penet_ratio9:s into t_he existing concrete at grout fill locations. The majority of these portable HEPA exhausters will exhaust to Canyon portion of the facility and subsequently be exhausted from the common stack through the new K:iN aba_te_rnel)_t system_. Tl,_e core drilling and grou_ti_ng of the K3 HEPA filter housings and the K3 filter pit will be performed using temporary containment equipped with HEPA filtered exhaust_ers exl,austing to die ambie_nt ai_r. The 1I1on_i_toring of these emissions is also described in Section 9.

4. Phase 4 -After completion of the-grouting activities, the existing Kl abatement system, which will not have been modified, wffl continue to venti°I.ate the sealed S0"'1'Ces (Cs and Sr ca:psµl_es) stored underwater in the pool cells. Both the Kl and K3N abatement.systems will be exhausted through a common stack where emissions from the facility will be monitored as described in Section 9.

There is no increase in the facility potential-to-emit resulting from this action as the radionuclide inventory stored a.t WESF h.a:s no.I incr¢ased arid in fact has undergone a decay of approximately one half0 life. The original 1998 40 CFR 61, "National Emission Standards for Hazardous Air Pollutants," Subpart H ''National Emission Standards for Emissions of l:ladionuc,lides Otl,er Than Rado!) from Department of Energy Facilities," source assessment (HNF-1974, Hanford Site Radionuclide National Emission Standards for Hazardous Air Pollutants Stack Source Assessment) calculated the unabated o_ffsi_te dose for WESF at 2 .. l !E+-01 rriiem/year. The updated cakula:tion provided in Table 3 places the unabated.offsite:dose at l.38E+0l mrem/year: a change due to updated dose factors and decay corrected inventory val_ites. After completion of the stabilizatiori activities, the radimmclide material available for release will be decreased significantly such that re-designation· of the WESF emission unit as a minor source would be possible and may be pUrsued as a future licensing activity. Appendix A contains a redline/strikeout version of the current FF,0 I License (WriOH, 2() 12, Radioactive Air Emissions License For The Department of Energy Richland Office Hanford Site License) with the proposed changes.

The WESF processes associated with the control of air emissions win transition through four distinct phases as the W-130 Project progresses. ht phase one,.the Kl and K3 abatement systems will continue to be operated to support routine activities associated with storage of the capsules while preparatory work is co)ldi(cted prior to the instaU.ation of the K3N abatement system. In phase two, the Kl and K3 abatement systems will be shut down to allow for connection of the K3N abatement system to the common stack with portable HEPA exhaust.,rs bei_ng used to control con_tarniriation. In pliase three, stabilization activities will be conducted with the Kl, K3N, and various portable exhausters in operation. In phase four, after the conclusion of the W-130 Project, the KI and K3N abatement syste_ms will be optirated to support the rmiti_n_e activities associated with the storage of the capsules.

During JJhase on_e, tlle l(_l abat_e.ment system is operattld to remove heat as well as to ensure that any potential buildup of hydrogen gas (H2) from hydrolysis is removed from the capsule storage (pool cell) area. The i<.:i abatement system is operated to maintain corita.miruition controls associated with the Hot Cells, Canyon, andTank TK-100. The W-1'30 Project prepa,ratory activitillS wiU consist of the installat_fon of utilities infrastructure. and concrete work for the placement of theK3N abatement system. Core drilling of the T~k Port wali will be perf0rmtld to ailow the exterior K3N abatement system inlet ducting to connect to the K3 Canyon exhaust duct-. Place1m:nt of the K3N abatemeIJ.t. syst_em and du_c_ting .up to the point of tie-in to the K3 Canyon duct will also be performed. HEP A filtered portable exhausters will be installed on on_e in!¢ duct of e_ach Hot Cell to provide contliiiiliiation control for the Hot Cells and K3 Duct during the time the K3N abatement system is tied into the common st.ack _iµid \l_l_e K3 Canyon exhaust duct (phase two). Routine surveillance and maintenance activities associated with storage of the capsules will continue to be perfol'l):).aj_.

Outing phase two, .the Kl and K3 abatement systems will be shut down to allow for connection of the K3N abatemen/ system to the IO i'.>®t arid common stack. As an alternative to the heat and hydrogen removal provided by the KI abatement system, an outside door from the capsul_e storage ar_e_a must b.e left open. The H0t Cell HEPA filtered portable exhausters will be operated to keep the Hot Cells and K3 Duct at a negative pressure relative to tlle \VllSF and ambient air spaces; These j>9rtable eicha:usters are classified as new major and minor point sources when theKl and K3 point source is shut down to perform 1:h_e Io al:>atement system replacement. The major point.sources are A Cell (W-225B-OOl),-B Cell (Ws225B-002), C Cell (W-2;~5B--OOJ), @d D~E Cell (W-225B--004). The ininot point soti!ces, Farid G Cells are combined under one emission point (W-225B--005). lri the Truck Port, modifications to the K3 Canyon exhaust duct will be perforined and it will be connected to the K3N inlet ducting. The fans and ducting downstream of the K3 HEP A tilt~ wil.l be disconJ1ectaj. from th_e common stack and the 225BB structure using C<'otgroioation control structures ( e.g., glove bags, tents; sleeves) equipped with HEP A filtered p_ort;ible exhausters. This portable exhauster is classified as new major point source (W•225BA--001). New ducting connecting the K3N abatement system t!xha\lSt to the common stack wiil be installed as shown in Figure 6. The Tank-TKal 00 v.ent lines will bdsolated from the existing K3 abatement

. system and reconneqed to the IQN ab_atement system so that the Tank TK-100 will be actively ventilated. This new linewill be routed to the K3N ventilation skid, and connect to the new d~ct upst,ream oftll_e ION ventila!ion skid. Aft aerosol leak test will be perforined on the K3Nabatement system prior to the start of any intrusive activities ( e;g., core drilling .and grouting) performed during phase three. Routine surveillance and maintenance activities associated with storage of the capsules will continue to be peifol'l):).,\X!.

lri phase three, the Kl and K3N abatement systems will be placed in operation. Activities conducted upstream of the K3N a_baternent syste_i:n i.nc:lud.e stabilization of Hot Celis A through F, stabiliia:tfon ofthe A Cell Airlock, stabilization of the K3 duct, stabilization of the K3 HEPA filter housings and IO fil/er pit, stabiHzll,tion of the hot pipe trench and K3 duct trench. Stabilization is. accomplished .through the injection of cementitious grout that will immobilize radioactive material to contain radjolggical contantlnation within WE_SF, while allowing capsule retrieval operations to continue using G Cell. The use of temporary contamination control structures equipped with :({EPA filtered exhausts -i,iill .b_e us_ed where intrusive work is performed. Use of the. portable HEPA filtered exhausters on each Hot Cell will continue until that cel_l is stabilized (grouted). During this phase, the Hot Cell portable HEPA filtered exhausters do not constitute point source emission pciin!s as tl_ley exhallSt into the i<.:iN abatement system. The K3 filter pit contamination control structure(s) portable HEPA filtered exhausteris a new major point soW'(;e (W-225BA--002).

Core drills will be performed where nec:essary to aJl()w plac@ent of grout. Grouting wiil b_egin inside the exhaust duct downstream of the K3 filter pit and inside the K3 filter pit to stop any contamination from

escaping fro111 th_es:e areas of th,e K3 exha_ust system dllring s11bsequent gro11ting. The general seq11enc_e for the stabilization groutingofWESF is:as follows:

• K3 Duct (225BB parapet chamber section) downstream of K3 HEPA filters

• K3 Filter Pit Chambers (Filter, V ajve and North)

• K3 Duct from G Cell to K3 Filter Pit

• K3 Duct under I-Iot Cells

• A Cell Airlock

• Hot. pipe trench

• K_3 d11ct ti:enc_}:i

• Hot Cells

Du.rii:tg stab1Hzation activities, i_t is necessary to C:cintroJ tlie potential spread of cciiltariiliiation in the Operating and Service Galleries, the Canyon area, and the Truck Port As th~ grout flows into placement locations, air, water vapor, and contaminants may be released.through the vent locations. This necessitates loc_al filtering at each vent cqnni:ct_ion when grout is being plac:ecL Each location utilized in the stabilization (grout placement) sequence will require a fill connection and a vent connection. The vent collll.ectfon allows the air displaced by the grout fill to be released, thus allowing the maximum fill height to be achieved. Wat~ vapor and radiologi_cal cor:iJanrin_at_ion wil) also be in the vent ail' str~. The methods used to prevent the spread of contamination are outlined in Section.6 ..

I;t,1 phase four, t_J:ie Ki ang K3N ab_atement systems are the final abatement controls required to siipport routine capsule storage activities. The K 1 abatement system ventilates the pool cells, truck port, service gallery, hot inariipiilator shop, and operating gallery portion of the WESF facility. The K3N abatement system ventilates the Canyon, HotO:H G, and Tank TK-100.

6 Existing and Proposed Abatement Technology Regulatory Requirement: Describe the existing and proposed (as applicable) abatement technology. Describe the basis for the use of the proposed system. Include expected efficiency of each control device, al_ld tl!e atlllual average vo\U111etric flow rate(s) in meters3/sec for the emission writ(s). WAC 246-247-110 Appendix A(6).

The abatement tecbllology re_quire111ei:its change as the W-130 Project progresses t!u:ough four distinc_t phases beginning with the existing capsule storage management and Hot Cell production process requirements. Sta_bilizati_on of contamiriation in the I-Iot Cells and eliniinaticiil of the Hot Cell prodiicticiil capability requires additional abatement technology for worker protection and to prevent release to the environment. The end point.abatement technology supports capsule storage management.

Phase One (Existing): The existing abatement technology consists of the Kl and K-3 HEPA filtered abatement systems exhausting through a coirim.cin stack. The stack height is 75.00 ft (22.86 m) with a diameter of 3.-50 ft (1.07 m). 'the average stack effluent temperature is 68° F (20 ° C) with an ~verage exhaust velocity of 42.20 ft/sec (12.86 m/sec). The Kl abatement system consists of two (2) pre-filters in series, two (2) HEPA filters in senes and tvvo (2) fans in parallel with one fail. at a time required to be operating continuously. The K-3 abatement system consists of one ( 1) inoperable d!,mist_er, oi:ie ( 1) inoperable heater, impingement vanes, two (2) parallelsets of two (2) HEPA filters in series with one set required to b_e in operation continuously and two (2) fans in parallel with one fan at a ti.me required to be operating continuously. .

10

DOE/RL-2015-50, REV. 0

The Kl abatement syste_m is designed to remove heat and aJ:iy potential hydrogen biiildiip from the pool cell area when the capsules are stored. The K3 abatement system is designed for the captµre of radionuclide particles created from work being performed in the Hot Cells, normal facility operations associated with surveill_ances of the Hot Cells a,nd Ca,nyon d_eck, ventilation of the. T.ru:ik TK-.10.0 condensate collection process andany legacy contamination.

Phase Two (Pre-st_ab~atfon): The W130 Project ven_t,lation upgrades involve replacing the K3 abatement system with a new K3N abatement system. To do this, the Kl and K3 abatement systems must be shut down uritil the K.3N tie-in is completed .. Temporary point source portable HEPA filtered exhalll!tei:s will be used to maintain contamination control for the Hot Cells. Active ventilation will allow the air movement to be controlled throughout all phases of the project. This redu.ces the risk of contaminated air escaping through joints around the cover blocks and other sources of in-leakage .. Temporary contaminati_on control strucwres equipped \Yith HEP A filtered exhaust will also be used during work to disconnect the K3 abatement system components from the common stackand the K.3 exhaust diict. Some of the key pre-stabilization tasks incluae isolating the K3 Filter pit, removing.and replacing the existing ducting between the 225BB (K3 Filter Pit) baj_ldµig and the existing stack, and removal and isolation of existing ducting in the Truck Port. These actions prevent flow through the existing K.3 du_c_t.

An accessible portion of the existing K3 exhaust duct (18sin. diameter) discharges air from the Canyon ru:id ,s located above the floor in the southeast coiner of the WESF Truck Port. This 18-in. diameter duct is routed below the WESF Truck Port floorwhere it oonnect_s to an existing 20-in .. diameter duct, which ventilates the hot cells. These-two lines are combined into one existing belowagrade, 24~in. diameter duct, which is routed to the existing K3 exhaiist system. The new K.3N tie-in consists ofremoving the existing l 8~in. duct connection to the below grade duct; then inserting an 18-in. diamet.er st.ainless steel tee and an 18-in. damper into the remaining l 8°in. diameter duct in the WESF Truck Port. The outlet of the Truck Port tie-in vvi.ll connect t_o a new 22-in. diameter duct utffizing an intermediate expansion duct section, which will penetrate the south wall ofthe WESF Truck Port and discharge to the new downstreaµi in-line heater~ The duct is upsized fo 22 in .. to minimize pressure drop and fan requirements, and is based on DOEHDB_K-1169-200.3, Nup_lear A_ir Cleaning Handboo_ls, duct velocity reqiiirements. The diict size is based on the maximum temporary (prior to the start of stabilization) system .flow rate of approximately 6,550 ciibic feet per niliiute ( cfm). Figure 9 shows the new K.3N tie-in design.

The G Cell permanent exhaust ventilation tie-in and the portable point source ventilationtie-ins will also be completed as part of the pre-stabilization activities. For temporary ventilation of Hot Cells A through F, these tie-ins consist of connecting the portable point source ventilator intake hose to the existing duc.ts currently used to route CaJ:iyon air into the cell ..

The portable point source HEPA ventilator unit will consist ofan optional upstream heat.er unit and filtration unit. The heater unit utilizes an upstream dust filter.and downstream.spark-arresting filter,.and is capable of heating the exhausted air to ap!)roXlll)!ltely I 75°F based on a nominal 300 cfrn flow rate. The heater unit is connected to the filtration unit via an 8 in. flexible hose, The filtration unit will consist of a pref_ilter, H_EPA filter, @d exha1,1st fan. Prefilters are included in each iinit as is a Flanders nuclear-grade HEPA filter. The HEPA filter is constructed in accordance wit;h MJ!,-F-51068 wit;h a minimum P-fficieilcy of99.97percent for particles of0.3 microns at capacity, and is di-n-octyl phthalate (DOP) te~ted at 100 percent and 20 perC:ent of nominal flow. The unit uses aJ/4-Hp motor, and features airflow control in the range of 100 to 500 cfm. The port.able J)Oint source ventila~.oi:s utiXized for cell ventilation are sized to be operated at an approximate nominal 300 cfrn. This flow rate will bound all required C:ell exhaust flow rates under all conditions. However, because the ventilators are designed to

op:erate at. ~O percent to i 00 percent (500 c(m) capa_city, ample ad}us~eht is ava_i)_able.to acx:oIIl_!IIOQat<: potential further refinement of the required flow rate during construction.

' I For temporary contamina.tion control s_tructures using IfEPA filtered exbausti:rs, the size 1!04 type of the portable HEPA filtered exhaust unit may vary depending on the size and level of contamination at the \il'ork site ( e.g., models Nilfisk GD930 up to Rl'S SP-1600). The models to lie used wiilutiliie a HEPA filter with a minimum efficiency of 99.97 percent for parti<:le_s of 03 micron,s at capa<:ity. . -

The K3N abatement system consists ofone (I) heater, two (2} HEPA filters in series and two (2) fans in paral_lel witli one fan at a time requiraj to be oper_ating continuously. No nmdij:ica_tions will be ma<ii: to the common stack or the Kl abatement system. Details of the paired Kl and K3N abatement system configuration are found in the phase four portion of this section.

Phase Three (Stabilization): Following completion ofthe phase two activities, the Kl abatement system will be returned to service and paired with the K3N abatement system exhausting through the common st_a_<:k. Figure IO is.th.e proce_ss fl()w diagrmp. for stabiiizatioi:i actlviti_es. Tile K)N venti\ation system is required to provide adequate exhaust of Hot Cells A to G and the Canyon prior to completion of stabilization during all phases of facility operation. These phases consist of ventilation at the start of stabilization activities, during stabilization activiti.e§, and post-stabilization 1!ftivities. The K.3Nexhaust .system will be adequate to maintain heat removal/hydrogen removal capability in G Cell. The K3N ventilation system wiil be iristal!ed prior to the initiation of any stabilization activities. During the grout filling of a hot cell, a portable exhauster with HEP A filtrat_ion is cot;1t;11:<:ted to the c1:ll iti the CanyC>n. The Canyon area is exhausted to the new K3N exhauster with additional HEPA filtration provided by .the t~mporary portabl_e exhausters us_ed for coritamination contr9l. hi addition, the K.3 ti\ter pit will have a containment enclosure with active ventilation in place during grout placement to further contain the spread of ariy conta.miruition .. Additional containment enclosures ventilated with portable HEP A filtered ~xha\!5ters ~y be u,sed d_wing 1:onstruction a<:tivities as required for contamiJ:lation control for the duration of construction and grouting activities,

Porta_ble point S()urce ventilation (described in phasetwo) wiil be employed to ventilate Hot Cells A through F as they are being stabilized. One of ihe two existing cell ventilation supply ducts will be connected to a portable point source ventilator; with the other supply duct providing grout access when th.e h_ot cell is st,ibilµ<:d, The air strl:3lll being ventilated is .assumed t() be at 100 percent relative humidity. To preclude condensate formation in the portable point source ventilators, an upstream insline·air heater may be provided a:s Pait of the portable ventilation package. Heating the air to prevent the dew point from being reached is more desirable than collecting and routing the ~ond,:ms_at_e. The J'.jlte_red exhaust from the portable point source ventilators will discharge into the Canyon and provide a negative pressure in the cell relative to the Canyon, which wi)l be ve~tilated via.the new K3N system. Tl!erefore, a negligible impact to the.new K3N System is anticipated.

Phase Foor: (post-st.abilization and l_'Outine capsule St()rage IIlllllageI_Il~t). Aft.er the Col_l)ple_t_ion ofth.e stabilization activities, the Kl abatement.system will remove heat and any potential hydrogen buildup fr.oll)s the pool cell.area wh<W, t_h_e <:apsµles are s_t_orecl, whi)e the K'.3N a_batement system wiil provide air cleaning for G Cell routine operations, the Canyon deck routine operations and the Tank TK-100 condensate collection process.

The proposed abatement system configuration consists of the existing common stack, the existing Kl abatement:system and the new K3N abatement system. The following information remains unchanged from the existing configuration. The cmlinion stack height is 75.00 ft. (22.86 m) with a diameter of 3.50 ft (1 .07 m). The average stack effluent temperature is 68° F (20 ° q wttl.i an average exha_llSt velpcity of 42.20 ft/sec (12.86 rn/sec).

DOE/RL02015°50, REV. 0

The Kl abatement system consists of two (2) pre-filters in series, two (2) HEPAfilters in series and two (2) fans in parallel with one fan at a time required to be operating conti;J.uously. The ~1 HEP A filter design has been sized to provide up to 24,000 cfm of exhaust flow volwne, The individual HEPA filters are d_es_ign_aj and tested to have a minimum removal efficiency of 99.97 percent. The leak testing performed on the abatement system must meet cir exceed the 99.95 percent efficiency standard_.

The following information details the ccinfigiiraticin of the K3N abatement system that.replaces in-kind the K3 abatement system. The K3N ab_atement syste_m cons_i_sts of o_n"e (I) l_rllat~, one (I) demiste_r, !\yo (2) HEPA filters in.series and two (2) fans in parallel with one fan at a time required to be operating continuously. TheK3N HEPA filter design has been sized to prcivii:le lip to 7,500 cfm of exhaust flow volume. The individual HEP A filters are designed llI).<i test_ed 10 have a minimum re_mova_l efficiency of 99.97 percent. The leak testing performed on the abatement system must meet or exceed the 99.95 percent efficilln:Cy standard. The dose calculations provided in Section 15 are calculated using a 99.0 percent· efficiency as an added measure of conservatis_m in _the event constru:Ction activi_ties inadvertently affect the filter- seaLAll major portions of equipment comprising theK3N system, which includes the in-line h1:at~r, JON ven!flation skid, fans and switching plenufus, are skid mounted. A damper located in the Truck Port transition duct will be manually adjusted to set the requ_ired flow r!lte i_n conjunct.ion with varying the K3N exhaust fan flow rate. The new exhaust fans will be fitted with Adjustable Speed Drives (ASDs) aaj new lllc:>tors.to provi_d_e ex.haust flow rate variability. Oiily cine fan will be placed in operation at a time and the other will be in standby. Figure 6 shows the general WES_F a~atement design layout. Figure 7 shows the K3N abatement train design detail.

An incline 35 kW heater is provided upstream of the K3N HEPA filters in the ducting. Figu_re 8 provides the design detail .. The heater is required to ensure the relative,humidity of the exhaust entering the pre-fi!tllr lµis bec,,n lowered t_o 70 percent or less per American Society of Mechanical Engineers (ASME) N-509. The K3N ventilation skid and in-line heater will be l_ocated on new co1_1c::rete pa<ls with surrounding bollards to protect the equipment from potential vehicle impact. In addition, fire-resistant insu)ation wiU be provided for the heater housing, the K3N ventilation skid components, and the fan switching plenum. The insulation will be permanently sealed into the housi;J.g of t_h~ h_eater !llld ~3N ventilation skid housing by the welded installation of stainless steel false panels. All welded components in the new K3N ventilation systllm, w_ith t_he exception of the carbon steel condensate drain encasement, will be fabricated from stainless steel.

Thi: h~ter hpusing will contain a flo_or drain at the b_ottoriJ. of the housing to collect condensate. In addition, the ducting will slope from the point of exiting tlie Truck_ Port to t_lie l11:ater, 811d llI).Y condensate in the duct will collect and be drained from the heater housing. The gravity drain system will route the condensate from the heater housing to a 1_1ew sea_! pot for collectitJ.g condensate. The s~l pot will be provided with a sight glass to allow visual indication of condensate collection. It should be noted that during K3N ve_ntHat_i_on systllffi operation, tlie seal pot is ahvays at the lower overflow level, and any excess condensate drains to TK-100. The seal pot will be designed to allow water addition to maintain the mi_nirn:UJ].1 iiqu_id level as weil as provide level indication. The condensate drajnage piping will be insulated and heat traced to prevent freezing.

The ducting from the heater \'\'ill b_e sloped to the K3N ventilation skid. The ducting from the. K3N ventilation skid to the fans and the 1_1ew ducti11g frolll t_l;ie fans to the Kl/K.3 stack will be sloped toward the.fans, where condensate drains will collect and route condensate to. the K3N ventilation s~d provided seal pot. The K3N seal pot discharge will also be routed to the.existing TK-100. Condensate is not el_(pected in tjles.e portions of the syst_elll due to the in-line heater and insulated system, but provision must be made should it form. Tank TK-100 will use the existing 2-in vent line connected to a _new :?-in. line discharging into the new duct upstream of the K3N ventilation skid for the following reasons: The

13

DOE/RL-2015-50, REV. 0

flow rate from TK-100 is intermittent and insignificant, only occurring when air is displaced by condensate draining into the tank. The bulk moisture transport via convection is also insignificant relative to the 5,400 cfm IJ1ini_nmrirstrea111 to which it vents. Baseco 011. this, the addition of the \ie11t st.ream downstream of the heater is a design feature to minimize the contamination of the heater, which has no upstream ra<liol)11clide filt,atio11.

7 Drawings of Control Tecllnology Components Regulatory Requirement: Provide conceptual drawings showing all applicable control technology components from the point of entry of radionuclides into the vapor space to release to the environment. WAC 246.247-110 Appendix A(7).

Drawings of K3N ventilation controls are maintained as part of the WESF K3N Ventilation Mechanical drawing H-2-836674.

8 Identification of Radionuclides Regulatory Requirement: Identify each radionuclide that could contribute greater than ten percent of the potential-to-emit (PTE) total effective dose equivalent (TEDE) to the maximally exposed individtllll (MEI), or greater than 0.1 mrem/yr PTE TEDE to the MEI. WAC 246-247-110 Appendix A(8).

The radionuclides of concern exist in liquid or particulate solid and solid forms. For purposes of estimating potential iind,actu_al emissions and resultant impacts to the maximally exposed individual (MEI), each radionuclide contained fo a hot cell or duct location is represented ·as curies (Ci). R_adionuclides of concern in:clude Sr-90, Cs-137, and all associ_ated daughter products. 'fh.e Kl aba_t_ewent system ventilates the portion of the facility where the cesium and strontium capsules (sealed sources) are stored. In t_his form, the ra:dioactiv_e ma~erial is not available for re.lease and, the,refore, is not included in the PTE calculations.The radioactive material available for release decreases as the stabilization activities move from location to location within the K3N abatement system ventilated air space. Table 1 identifies the radionuclides and PTE associated with each hot cell and duct location. The information used to construct Tables I and 2 is obtained from ECF.HANFORD. 15-0018, Potential to Emit Calculation for WESF W-130 Radioactive Air License Revision, which updates the 2002 ancl 2008 PTE calculations contained in HNF-1974, Rev. I, Radionuclide National Emission Standards for Hazardous-Air Pollutants P{!tentia,l-to-Em,it Assessineiit, and HNF-1974, Rev. 2, National Emission Standards for Hazardous Air Pollutants (NESHAP), Subpan H; Radionuclides Potential-to-Emit Calculations. Table 2 provides the inputs for calculating t_he PTE TEDE to the M,EI for tewporary contami_naliob control struct11re usage associ_ated with the K3N exhaust duct tie-in to the common stack (Table 4) and grouting of the K3 Filter Pit (Table 5). These tables are found following the reference section. The following information is provided by project phase where phase ol)ds C:apsule riianageinejlt and pre-coristruction activities; phase two is capsule management and installation of the K3N abatement system; phase three is capsule management and stabilization of the K3 Filter Pit, Hot Cefls, and- K3 buct; and phase four i·s poststabilization and routine capsule managemerit and future transfer activities to a dry storage location. Prior to the start of stabilization activities, both Sr-90 and Cs-137 quantities for the entire facility contribute greater than 0.1 rirrem/year PTE TEDE to the M_EI. After stabilization activities have been completeci!, no radionuclide contributes greater than 0.1 mrem per year PTE TEDEto the MEL

Regidatocy Requireilleitf: Descri_be the effluent monitoring system for the proposed control system. Describe each piece of monitoring equipment and its·monitoring capability, including detection limits, for each radionucli_de that coill_d con.tribute greater than ten percent of the PTE TEDE to the MEI, or greater than 0.1 rnrem/yr PTE TEDEto the:MEI, or greater than twenty.five percent of the TEDE to the MEI, after controls. Describe t_he method for moni_t_oring or calculating those nidio_nuclide emissions. Describe the method with detail sufficient to demonstrate compliance with the applicable requirements. WAC 246-247-1 JO Appendix A(9).

The potential unabat_ed offsite dose associ_ated wi_th t_he K3N ven_ti°l_ated area for pre-stabilization operation and stabilization activities is calculated to be greater than 0.1 rnrem/yr and requires continuous monitoring. The PTE associated with post-stabiliz_ation operatiorjs are estim11ted to be less than 0.1 mren1/yr. The common stack (Kl and K3, or K3N) effluent monitoring system is operated.under an alternative sampling system method approved by EPA (OAQ-107, Approval of Alternate Monitoring Procedure by tlie Siaie of Washington, August 1999) and WDOH_ (AIR 99-501 ). The replacement jn kind of the K3 abatement system with the K3N system does not alter the effluent flows into the common stack in terms of volume and radionuclide content. The Kl abatement system vvi_Ji n,m_ain unch_anged as part of the K3N ventilation upgrade and will _continue to exhaust through the common stack.

In phase one, the effluent monitoring system located in the common stack will operate during pre-construction activities, and ongoing facility operations. The effluent monitoring system is designed to detect beta/gamma radiation based cin theradicinuclides present at WESF. ACAM is also located in the stack sample cabinet fed by the sample line flow splitter: The effluent monitoring system is composed of a record sampler and associated sample collection devices for compliance data collection using an approved alternate method. This method is·discussed in detail in the phase four section. Following are the components of the record sample collection system:

19

·\

DOE/RL-2015-50, REV. 0

• Sample nozzle(s) (probe)

• S,@ple trll!lsport I_i_ne

• Record sampler with sample collection media

• Flow meter (rotameter)

• Gas mass flow totalizer

• Vacuum source

The record samples are collected on a replaceable sample media every two weeks and sent to an offsite laboratory fof analysis. The sainple media ate also composited on a quarterly basis for isotopic analysis (Sr-90 and Cs0 137). The bi-weekly analysis is focused on gross beta/gamma emissions using instrumtintatio~ wi_th a minimum det_ectable cmicentration (MDC) sensitivity of at least I .9E-I 5 µCi/inL (gross beta/gamma) or a minimum detection limit (MDL) of I.OE-I I Ci (gross beta/gamma). The MDLs for the composited samples are 4.0E-14 Ci (Cs-I 37) and I .OE-Ii Ci (Sr-90). The laboratory analytical and quality control protocols follow the Method I 14 requirements. Sample collection data (analytical and· sample flow) are accumulated and converted to a concentratio_n (µCi/mL) using the A!Jtoma~_e:d ~ar Coding of All Samples at Hanford software program. The calculated concentrations, along with the WESF maximum common stack effluent flow volume, are used as inputs into dose calculations using CAP88-PC software.

In phase two, the common stack effluent monitoring system will be shut down as the KI and K3 abatement systems will be shut down for connection of the K3N abatement system to the common st_ac_k and K3 Dud. The potential unabated offsite d_cise associated with disconnecting the K3 abatement syst_em from and connecting the K3N abatement system to the common stack is calculated to be greaterthan OJ mrem/yr (Table 4). An alternate m_on_itoting m¢thod dui:ing phase two is proposed for the continuo_us and Periodic Confirmatory Measurement (PCM) monitoring requirements.

To verify continued low diffuse and fugitive enlissio.ns froin tlice ventilation construction activity,.the near faci,l.i.ty monitoring (NFM) network data for stations N481, N532, N976, and N973 will be trended on~ mo11thly basis until the construction activity is completed.

In pha:se tllfee, the Kl and K3N abatement systems will be in operation with the·common stackeffluent bei11g monitored as described in phase one. Within the K3 ventilation boundary, contamination .containment structures ventilated by temporary portable HEPA filtered exhausters will be used during the grouting of the Hot Cells and K3 Duct as ALARA controls.

• In phase four, the stabilization activities will have been completed, thereby reducing the majority of material avrulable for release. The estimated P'I'E will be below 0.1 mr~m/year. The Kl and K3N abatement systems will be in operation to sup~rt the management arid future movement of the stored capsules to dry storage. The record sample collection system described in phase one will not have been modified and will continue to be operated in accordance with the approved alternate sarriplirig methooology.

The approved alternate sampling system methodology addresses two deficiencies associated with the 40 CFR 61.93, "Emission Monitoring and Test Procedures," and ANSI NI3.I-1969, Sampling and Monitoring Releases of Airborne Radioactive Substances from the Stacks and Ducts of Nuclear Facilities, standards underwhich the WESF common stack sampling-system was designed. One deficiency involves the use ofan isokinetic sampling probe that do.es not provide equiannular sampling. A line-loss study coupled with a nozzle equivalency study was conducted and demonstrated the representativeness of the ~ample coBected from tl;le ex.i,st.i,ng sample rake, Th_e other deficien:cy is the flow measU:re):nerit location that does not meet the Method I "eight and two" rule. The'installed flow sensing instrumentation does not meet the M_ethod 2 requirements, as it i_s locat_ed in an un_qualifi_ed l_oca_tion.Appendix B cO:n_tai_l)S the DOE-RLJetters (98-EAP-I 75, "Response to State of Washington Department of Health (OOH) Request for Information on Waste Encapsulation and Storage Facility (WESF) 296-B-i0 Stack;'' 99-EAP-109 "National Emission Standards for Hazardous Air Pollutants (NESHAP) Request for Stack 296-B-I0 Sample System Equivalency, Waste Encapsulation and Storage Facility (WESF)") that detail the :res_olution of the de_ficielici_es.

Summarizing the resolution provided by DOE-RL and approved by EPA and WDOH, a fixed design flow capacity of 24,390 cfm is used to calculate emission rates .. by applying analytical data obtained from

cO:ntinimus sampling. Th_e existing alternate inoliitoring approval utilizes a maximuin flow volume to calculate emissions to avoid the under-reporting of emissions. It is proposed to continue using the approved alt_emate sampl,il)g system Illethodofogy U:sh1g a m_aid111iim rated de_sign flow volu)'ne of 24,540 cfm based on a 150 cfm increase in the K3N fan rated capacity above the K3 fan rated capacity. Using the co!l1bined Kl and K3N maximum design flow volume will reduce the potenti.al to und_er-report emissions as the-calculated emission rate will be based on a higher effluent volumetric flow applied to the analytically determined _radionuclide concentration collected at a lower effluent volumetric flow. Post-stabilization ventilation flciw volumes are exp_ected to range from 18,500 to 22,000 cfm. The effluent volumes.calculated using the velocities encountered during-the velocity transverses performed in support of the alternate sall1plirig system metho_dology ranged from a lciw of 15,167 cfm to a rnaximiiin of 25,509 cfm which bracket the expected common stack effluent operating flow volume range.

In addition, the near facility monitoring network data will verify co_ntinued low diffuse and fugitive e_®ssio_ns from the WESFc The near facili\y moni_tori_ng program meets the Me.thod I 14 requir_e!l1_e_l)ts and is well suited to detect this type of release.

The radionuclides in inventory are present as liquid and particulate solids and solids at ambient conditions.

12 Release Form of Each Radionuclide

Regulatory Requirement: Indicate the releaseform of each radionuclide in inventory: Particulate solids, vapor, or gas. Give the chemical form and the International Council for Radiation Protection (ICRP) 30 solubili_ty class, if known. WAC 246-247-110 App~ndix A(l2).

The radionuclides.Sr-90, Cs- j 37, and all associated daughter products are released as particulate liquids and solids and .solids.

13 Release Rates Regulatory Requirement:.Release rates: New emission unit(s): Give predicted release rates without any emissions control equipment (the PTE) and with the·proposed control equipment using-the efficiencies clescrjbed in subsection six (6) of this section.

Modified emission unit(s): Give predicted release rates without any emissions control equipment (the PTE) and with the existing and proposed control equipment using the efficiencies described in subsection six (6) of this section. Provide the latest year's emissions data or emissions estimates.

In all cases, indicate whether the emission unit is operating in a batch or continuous mode. WAC 246-247-110 Appendix A(l3). '·

The replacement of the K3 abatementsystem with the K3N abatement system represents a replacement in kind as defined by WAC 246-247-03.0(22). The stabilization of the K3 Filter·Pit, Hot Cells, and K3 Duct represent a modification as defined by WAC 246-247-030(16) and reduces the radioactive material available for release, thus changing the end state PTE. The PTE is defined in WAC 246-247-030(21).as the rate of release of radionucHdes from an emission unit based oh the act_ual or poten_t_fal discharge of the effluent stream that would result if all·abatement control equipment did not exist, but operations are otherwise n_ormaL The PTE is det_ermined by 111ultiplying the APQ, ciis_c_uss~:<I in Se~tion I 0, and applying the release factors defined in WAC 246-247-030(21)(a) for liquid and solid particulates (10-3) and solids (I 0-6). An esti_mate of the unabated a:nd abated dose in rnrem/yr to an MEI is detennined by applying the dose-per-unit release factors as published in DOF/RL-20.06-29, Calculating Potential-to-Emit Radiological Releases and Doses. Dose-per-unit release factors are·presented for both the·onsite and offsite ii,:dividual, wit_h consideration give!) for t_he relea_se poi_nt (Le., less th.an.a 40 meter stack height) in Tables 3, 4, and-5. The K3N emission unit is actively vented on a continuous basis and temporary contamination control structures are actively ventilated on an intermittent basis, dependent upon work activities being conducted within the structure.

14 Location of Maximally Exposed Individual Regulatory Requirement: Identify the,MEI by distance and direction from the emission unit(s). The MEI is determined by considering distance, windrose data, presence of vegetable gardens, and meat or miJk producing anim_als at 11mest_ric:ted areas s111To11ndi11g the ernissi01_1 Lin_it. WAC 246-247-110 Appendix A(l 4).

The otisite MEI relative to elllissions from the WESF is located at the Columbia Generating Station, approximately 16.6 kilometers east southeast of the Plutonium Uranium Extraction Plant (PUREX), conservatively chosen to represent 2_00 East Area. The offsite MEI resides near the Hanford Site, approximately 20.2 kilometers east southeast of PUREX.

15 Total Effective Dose Equivalent to the Maximally Exposed Individual

Regulatory Requirement: Calculate the TEDE to the MEI using an approved procedure (see WAC 246-247'085). For each ra<iion:,,icli<ie identifie<i i_11 subsec_tion (8) of this si,ctio11, d_etetmitie the TEDE to the MEI for existing and proposed emission controls, and without any elllission controls (the PTE) using the release rates from subsection (13) of this section. Provide all input data used in the calculations. WAC 246°247.-110 Appendix A(l5).

Dose estimates for unit Ci releases of selected radionuclides were calculated for emissions from the 2_00 East Area .. These dos_e i,stimates were calcula_ted for a11 O:nsite member of the public workh)g at Columbia Generating Station, who works within the Hanford Site boundary, and who eats food grown regionaily (DOE/RL-2006-29). Similarly, dose estima_tes were calculated for an offsite member of t_he public residing near the Hanford Site (approximately 20.2 kilometers to the south southeast of PUREX), and consuming food produced entirely at the residence location (DOE/R.L-2006-29).

Using the uni! dose factors and the release rat"s as di_scussed i11 Sec:t_ion 13, estimated potenti_al abat"4 and unabated TEDEs to.the offsite and onsite MEis are shown in Table 3. Unabated elllissions in curies were determined by applying release factor l .0E-03 for iiquids and particul_ate soiios and l .OE-06 for solids (based on the HNF-1974 assumptions) directly to the APQ inventory values. The K3N abatement system unabated dose in mrem/yr to the MEI was determined by multiplying the unabated release in curies and the dose-per-unit-release factor from Table 4-7 or DOE/RL-2006-29, Rev I, Calculating Potential-to,Elllit Radiological Releases and Doses for a stack height of less than 40 meters. The abated dose in mrem/.yr was d"termined by iii_ultiplyi_ng the offs_i_te unabated dose liy 0,01, wlri_c_h represents an inplace tested HEPA filter particulate removal efficiency of 99.00 percent as a worst case to·account for any minor lea:ka:ge inadvertently incurred during construction activities. Tl;le sam_e approach was used for tJ:ie temporary contanrination control structures except a release factor of I .00E-03 was utilized to represent a worst case as core drilling will be performed as part of the stabilization activities, whlch could generate particula!.es froiii the soli_d iiiateri_al with th_e ex_ception of t_he B Cell Tank Bottoms, which us¢ an l .OOE0 06 release factor (fable 2). In addition, 'the temporary contamination controlstructure for K3N exhaust duct connection took credit for the K3 HEJ>A fi)ters leakage control efficiency.(a! 99.0.0 percent as a worst case to account for any lllinor leakage inadvertently incurred when disconnecting the K3 fans from the K3 HEPA downstream exhaust duct), as those filters would be left in place during the duct changeover activity.

The existing pre-stabilization and stabilization activities (Phases 1,.2, and 3) calculated unabated offsite an_d onsite TEDE to the MEI (Table 3) are estimated to be for the foilowiilg:

• K3 Ductare 9.82E-03 mrem/yr and 6.01E'04 mrem/yr, respectively

DOE/RL,2015-50, REV. O

The WESF K3N ventilation system is required to comply with several technology standards other than ASME AG01. The following text ctiscusses compliance with these other techn_ol_ogy standards.

• ASME N509-1989, l'{uclear Power Plant Air-Cleaning Units and Components,.applies mostly to design requirements for testing fans, dampers, and housings. Most of the requirements of ASME N509 have llligrated to ASMJ;: AG-I, ai(d are to be irripl_emeilted via reference to ASME AG-I jil later revisions of ASME N509. ASME N509 will be cited as an applicable standard in vendor documentation .. Files and other projec.t docu_ll}entation ad.dress requirements cited in sectioil.s of ASME N509 that have not been migrated to ASME AG-I, including the following:

~ ASl\1.E N509 Section 4.1 (general functional design): Prefi\ters, h!':aters, and HEPA f'ilters, including efficiency requirements, will be·specified by the project as required by ASME N509.

ASl\1.E N509 Section 4.2 (functional design parameters): Project specifications wiil include exhaust flow rates, pressures, teitiperatufes, airstream composition (e.g., humidity, moisture, chemical composition, and specific contaminants), radiation, structurai loads, and environmental con.ditions, as required by A.SME N509.

ASME N509 Section 4.3 (installed size or capacity): Capacity will be based on individual air-cleaning components of the system, in accordance witll AS°ME N509.

ASME NS.09 Section 4.4 (environmental conditions) includes requirements in ASME AG-I, addressed elsewhere in this document. Project specifications will address environmental conditions, as required by ASME N509. References to In:stitute of Electrical and Electronic Engineers (IEEE) 323 and IO CFR 50.49, "Environmental Qualification of Electric Equipment ltnport.a11,t t.o ~afety for Nuclear .Power Plants," are not applicabl',, because no Class l.E or comparable electrical equipment is required for the K3N ventilation systems. Equipment will be environme11taily qualified per project specifications, relying primarily on pubiish!'d vendor d_ata, commensurate with impacts on operational and quality assurance requirements.

ASME N509 Section 4.6 (fan peak pressure): Ductwork, dampers, and housings will be tested and rated to a negative pressure in excess of the peak pressure of the exhaust fan, meeting the requirements of ASME N509.

AS.Mil N509 Sec:timi 4.8 (m)lin.taiO:abiHty): Ffl.ter liousirig d_oo.rs .arid test ports will be safely accessible by workers standing on grade or OSHA-approved work platform, with the necessary clearan·ce to· facilfrate filter change·out and testing. The exh·auster controls and components requiring routine calibrati_on or maintenance will be accessible by workers standing on grade or on the platform. No manned entry will be required for maintenance. Therefore, such requirements as stairs, l.ad!iers, or servic:C ga.fl.eries, or the 3-ft in.temal acc.ess spacing for inaiil.tenance required in Section 4.8.2 of ASME N509, are not applicable ..

ASME N509 Section 4.10 (adsorbent cooling) and 4.13.b (adsorbent testability): The design does not include adsorbent beds; therefore, these sections do ncit apply.

- ASME N509 Section 4.12 (insulation): Insulation will not prevent access to·any bolted constniction, do.ors, test gorts, cir iristruinentation, and d,oes ilot result in penetrations through the pressure boundary, in accordance with ASME N509. These areas will have removable sections of insulation to aUow access.

• AS°ME N.511, In-Service Testing of Nudea_r Air Treatm_ent, Heating, Ventilqting, and Air-Conditioning Sysiems, for-testing and visual inspection of the filter hoilsings and filter train assembly. The assemblies will be designed to enable routine in-place leak testing and efficiency testing ofindividl\al ins.tailed high-efficiency partic11late air (HEPA) filters in accordanc_e with ASME NS 11 ·: The completed exhauster skids will undergo visual inspection by the exhauster fabricator before acceptanC:e testing, in accorda_nce with Sec_ti_on 5 of ASM_E NS 11.

• ASME NQA0 ] Quality Assurance Requirements/or Nuclear Facilities Applications, Rev. 12, which is cited throughout ASME AG-I, and includes QA spe~ific sections (generaily the 8000 group for each.section). These sections provide component level detail discussing ASME NQA-1 compliance. In addition, the design, procurement, and installation of the K3N ventilation equipment will be evaluated to ASME NQA-1 reqiliremerits and on the CH2M HILL Plateau Remedfati_on Company (CHPRC) Evaluated Supplier List (ESL).

• T(:le W-130 project will route tJ:ie K3N ventil_ation system effl_ilent to an existing stack. Mod}.ficatimis to the stack, other than connecting new ducting, are not required because ofthe·project. The following standards are appiica_ble to st_ack monitoring systems. The existing stack complies with these, as detailed in Section 9:

- ANSI Nl3.l-1969 Sampling and Monitoring Releases of Airborne Radioactive Substances from the Stacks and Ducts of Nuclear Facilities

- Title 40, Code of Federal Regulations, Part 61 (40 CPR 61), Subpart H, National Emissions Sta:ndar_cls for E_missions of Radionuclides other than R_adon f_rom Dep_artment of Energy Facilities ..

The new K3N ventilation system will fully comply with, meet the intent of, or have justified exceptions identified for, applicable code requirements for the performance, design, construction, testing, monitoring, and QA of equipment used in riildear safety-related ventilation and air treatment systems in nuclear facilities. The system will be acceptable in altaspects of ASME AG-I and other technology standards, as reqilired by the WAC 246-247, wi_t_h th_e ex_ceptiOns id_enti_fjed i_n the A,G-1 Con1p(i'!flce Matrix.

Three sell of lntormatlon are required to nm lhe model: system pn1pcnia and paramelm (Table l), tranSport aysiem confiFl,tion (Table 2) and particle siu information (Gtissmeyer, 1977) (see Table3).

One problem wu encountered in the system eonfigurallon. The sample line pau111 Into 1111d out of a flow splluer and Deposition 4_0 does not model Bow aplitters. Because of lhis problem the t,ansport system wu divided into three sec&lons. Section 1 represem1 the sample line from the . end oFthe probe to the Bow spli11er. Ser.lion 2 is die Bow splluer and Sec:tlon 3 is from lhe exit oftlle flow splitter to the record sampler_ The data for Secilon l is shown in Table 2.

Secuc.n 2 represented the Sow splitter_ In order 10 esllmite the line loss for the flow splitter, Pro(easor Amy McFuland o"exas A&M wn con11eu:d ,114 a request was made for Ill) estiimte of deposition in the flow spliuer. Patticle size i11f'411111BllOn (3.S, S 1111d 10 micron), flow ·mes, and dimensions of the si:u: of the channels in the splitter were provided to him (see Table l ). Based on this in.formation, an estim~ of penetration wu provided for lhe flow splitter (McFarland personal co~nicallon. 199S).

Section 3 represents the sample line _from the flow spOtter to the r~ sample (Table 2).

No recent meaSl)ferne nts of panicle sizes have been made for t.he 296-B-10 stack. However, paniCle size measurements for the K.-3 dua ventilatlng IO the 296-8-1 O stack wm made in 1977 (llllachment) (Olissmeyer. 1977). Five ~ of mcuurements were made usins an impactor with four stages and a backup fitter. To determine the penetration for these measurements, particle -sizes were selected to represent each of the stages used in his measurements: 7, S. lS, 2.6S, 1,55, and 1.1 microns. These sizes of particles were used as input into the Deposition 4.0 model aloog with the data in Section I and 3 (Table I and 2). Please note that the LI micron is an

· overestimate orthe·size of particles on thebackllp fil~er sinee i_t will collect p~ies, I.I micron and its use in Deposition 4.0 will overesti.mate the line loss ror this siic fra.aiolL Also 7 microns was used to represent the first sage of the impactnr. This will underestimates the alze on that stage since this atase collects particle :t 7 microns. However, the p1111etration fraction for 7 microns is only 0_031 through Section I, 2 and 3, i.e. O.OSl•0.65*0-925 • 0.031. This wall ftacdon indicates that Ver/ little inftuence is felt by particles larger than 7 microns. Therefore the auum_ption of? microns panicles on the first stage will cau.se an ill$i.gnificant error in the total penetration.

The input to Deposition 4.0 is ahown in table I and l for the particle sizes li5ted in tho first colut11n of Table:;_ The total penetration for Runs I throug213 are 70.4%, 82.S¾, 4S.6%, 55.4% and S7.4% with an average penetnilion of 62.2"/o for the sampling line.

11ng Stucly conducted by Battelle-NorthWest under the spansorshtp of the Atlantic Rtchfield Hanford Canpany the particulate effluent seaip11ng systl!III of the major WESF ventilation exhaust (296-B-1D Stack) was ·investigated in detail and the results were c011111Unfcated to ARHCO tn two·reports.C1•2) Th~se reports concluded that tf the effluent radtoacttve particulates were larger than 2 l,llll aerodynamic equivalent "diameter (AED) that signlt'tcant errors In co11ected samples could occur. In giseous effluent samp1tng

·criterja issued by ARtltO, performan::e req11irements are estab1'1shed for sampltng particulates as large e.s 10 lllD AED and a c!lllracter1zat1on of effluent particulates h required. A:; a result. the P4rtlculate and Gas· eous Waste Research Section, Battelle, Pacific Nortt:west Laboratories, was requested to obtain particle size data for the exhaust ,~·the K~3 ventilation system which is considered to be the pri111ary effluent containing airborne radioactive particulates.

2.0 SIHfARY

Three simples of particulates fn the X-3 exhaust duct, 1/aste Encapsulation and Storage Facflfty (IIW), were collected using a cascade impactor and concentrations and particle size distributions were obtained for 137cs and 90sr.- Two of the SIJIIJ)les were collected when tha fac:1Hty was shutdown a11d processing had ceased. The first of th~se two samples did not contafn Hfflclent actfvfty for accurate analysis. The th1rd sample WIS collected after process Ing resumed and the exhaust was bei 119 f11 tered by the standby HEPA filter unit.

The analyses showed that under both plant operating conditions ttiat the X-3_effluent concentrations of the two radlonuclfdes were well below ERDA guidelines for acceptable ,release, however, the concentrations were tw orders of magnitude higher when the plent was operational than when Jt was shutdown. Whfle the facility wu shutdown the activity mean. aeroeyna:mic equivalent diameter (AM,\O) for radionuclide bearing particles was 5-8· 11111 for 90sr and submtcron for 137cs. When operations resumed and th~ effluent was switched over to the standby fflter unit the 90sr AMAD decreased to 3-4 µm and the 137cs AMAD Increased to the same size IS the 90sr bearing particles. Earlier reports have shown that ft ts not likely that the exfstfng effluent sampling ~stem fn the 296-8-1D stack will collect representative samples of particulates of the stze distributions found; however, the deviation shou1d not be larger than an order of magnitude. If the 1114gnltude of the el'l'Or in samples collected by the existing effluent sampler 1s to be Investigated further, we recoamnd using an aerosol tracer tecllnfque,

Table 2 also shows the am:i~nt of 137es and 90sr f~und fn the probe and inlet to the impactor and the total activity tnc1udfng that found fn the 1mpictor. The per'c'enhge of the actfvfty found fn the inlet ranged from 8-211 (8-121 for Just Run5 2 and 3) of the total. The 1ctfvfty fn the inlet was not fractionated by p&rtfcle sfze. The AMAOs discussed abOve ere valfd ~~sum1~g that the materf.ll deposited 1n the inlet was of the same size distribution u the material in the Impactor. It is more conservative to essllGle that the material deposited 1n the fnlet has a particle size greater than 7 IJffl AED. Usfrig this assumption the 111&terial fn the inlet 1s added to the first ill1J)actor stage and the CW1111latfve percentages are recalculated and p1otted yfeldfng the larger AIIAlls also ltsted In Table 2.

5.0 DISCUSSlOH

During the periad covered by the sampling runs the status of WESF operations va.l'ied co11s1derably •. During Runs 1 and 2 the plant was shutdown due to a strike; however, prior ~ Run 3 a ces1UIII encapsu1at1111i run was performed and the ventilation exhaust was switched over to the stand-by HEPA

filter bank shown 1n Figure 1. The exbaust filter switch 111s made in response to an upsurge 1n l!Ctivity collected by the ·effluent 11111p1fng system. Run 3 was initiated the day after the ftlter bank sw1tcflover. ~ring Run 3 two cesium encapsulation runs were performed and ten strontium capsules were produced. Thus, Runs 1 and 2 were performed men there were no procHslng · operations in the plant and Run 3 was performed during routine operatons in the plant and when the effluent was being treated by a different HEPA filter unit.

. .

The results of the sampling experiments show marked differences in the · effluents from .these tld0 periods. During the shut-down period the concentrat1ons of 1~7cs and 00sr were very lOl'I (10·9 ptf/ml); hoWever, during processing operations and with t different effluent filtration unit the concentrations were M order$ of magnitude higher (10·7 pCl/ml), though. - * . stfll low compared to ERDA gutdeliries. Particle she distributions were also markedly different during the two periods. During tlle shut-down period the .9Dsr- and 137cs- bearing aerosols had NIADs Of 5-8 11111 end <0.5 jllll respectively; however, during the processing period the AHADs ranged epproi_ti.mately 3-4 iim for both radionuclides. Thus the AHAD for 90sr decreased when tlie plant went operational (5 11111 to 3 .ldll) and the AMAD for 137cs increased under the same conditions.

The tnc~ase fn 90sr and 137cs concentrations in th.e effluent ts probably due to the plant gotng operational. The changes fn particle size dtstrtbuttons ere not easily exple1ried because there ere secondary mecllanls111S for

generating rad1onuclfde bearing aerosols ar.d changing their size distributions whtch ~re not -directly related to the operattons 1n the cells.

Tbe NWls found are relatively large compared to what would be eicpected

downstream from the HEPA ft1tl!r unit. Thfs can possfbl.Y result from

leaks 1n the filter unt,t or the c:onti1nat1on of the sm111 IIIIOllllt of

partic:les penetrating the filter unit with large inert partfc:les generated downstream of the filters and upstream of the sanq,11ng location. The c:auses for c:hangfng partfcle sfzes can only be apec:ulated and the possfbflftfes are numerous.

The data does indicate that the 90sr and 137es are carried u lllfnute contaminants on larger •carrier• particles. For example, the total 90sr collected during Run 2 WIS 58. 1 pCi. Assuming that 90sr (specfffc activft;y O 141 Cf/g) WIS the only strontium fsotope present, that represents

5.9(10-13) 9rams of pure SrF2 tthfch is roughly equivalent to a single

spher1c:a1 particle of 1.3 11111 Af:D. Bec:ause there was 90sr collected on all the iq,actor stages and the Indicated NIAii was at least 5 µm, this indicates that the 90sr was only a mfnute contaminant on larger carrier particles.

The same can· be concluded for 137cs also. The total 137cs collected during Run 3 fs equivalent to a single spherical particle of pure 137esc1 of 4.2 i,m A£D whtle

0

tl1e AHAD was 3.2-3.4 i:m and 137cs was found on e.11 of the tq,actor stages.

The presence of the "large• radfonu_clide bearing particles does affect

the accuracy of the collected effluent partfc:11l1te SIIIQ)les. M pqinted · out In the other ·l'.'1!ports addressing the effluent SIIIQl11ng system, (1 ~2) the existing effluent s1111111ing system probably dD!ts not collect representatln samples of parttculates with a 3 11m A>1AD or larger. The deviation frclin

representatfve samplfng 1s probably lus than,an ol'der of magnitude, but 1t cannot really be measured without In place testing with a tracer aerosol

technique.

!)ear Mr. Rasmussen:

This letter is in res~nse to yciur su_lill)i~I "97-EAP-S66" d~ i~ J, 1997. II concerns a request for approval of aliemati ve sampling system for the 296-B-10 Stack. My staff has reviewed the information provided. ·

Based on l.l!aI revi_ew i have detennined that the. 296-B-10 Stack requires continuous monitoring in ai:!'()rcllince with 40 CFR 61.93. The existing ~J,l.it<>ring proced111'.C.S, as approved by the State of Washington in their letter toYoil of May 19, 1999, are hei:etiy appro~asaii alternative procedure in accordaru:e with 40 CFR 6l.93(4Xi). These procedures are sufficient to cltaracterize the effluent fur·the purpose of the NESHAP, and are unlikely to underestimate the true em_issions.

If you have any questioils regarding this approval, please caU me at (206)5S3'2963, or Jeny Leitch at (206)SS3-7660 for technical matters.

NOTIFICATION OF OFF-PERMIT CHANGE P~rmit Number: 00-05-006, ~enewill 2

This notification is provided to the. Washington StateDep~ent of Ecology, WashingtQ!l State Department of!J.~, and the U.SiEnvironmeJJ~I Protection Agency as a no_tice ofait off-permit change described as follows.

Tlie following changes are allowed pursllallt to WAC T73-40 I -724(1), WAC 173-40 I, 724(2), and WAC 173-401-724(6): I. Cbailge is not specifically addressed or prohibited by the AOJ> terms and conditions; 2- Cluuige does not weaken the enforc~j)ity of the existing AOP CO!)ditioris; 3. Cµatige is not a Title! modificatj_o_11 or subject to the acid rain requirements under Title IV of the FCAA; 4. Change meets all applicable reqliire111ents and does not violate an existing permit tenn or condi.1:ion; 5_. Change has complied with appHcable prifoonstruction review req11_iremenis established pursuant to

RCW 70.9.4.152.

- .. Descriotion of the cban1>e:

. .. . - .

.. ..

The proposed action for this Notice of Construction Applicatio11 (NOCA)is to modify the eiµsting Waste Encapsulation and Storage Facility (WESF) FF-0 l license arid license major or 1_ni11or point source. porta_ble exhaiisters to.support the W-130 WESF Stabilization and Ventilation Project (W-130 Project) (WAC246-247s060(1)). A replaceiilent-inskind oftlie ex:isting K3 abatement sy*m with the ION abatement system utilizing the existing ef'flµent monitoring system is proposed. Additional ~temeJJt tecliilologies and an alternate mQnitoring methodology for portable exhausters are propose_d to support the stabilizaticm actjvities of the WESF Hot CeUs .. the work will be condu~d. in four ( 4) separate ph~s. The end state of the W-130 Project wfil result in WESF being classified as a minor point source .

. . . .. - .

Date of chaii2e: <To be orovided in the a2encv annroval order.) ..

. .

Upon receipt of the approval ·order by WDOH and acceptance of the approval order by DOE/RL . ..

Describe the emissions resuliin2 from the chanl!e: There is no increase in the facility potential,to-emit (PTE) resultiiig from this aftjon as the ra4ionuclide _ . invent9.ry stored at WESF has not incfe~.d and in fact has undergone a decay of approximately one half0

life. The original 1998 40 CFR 61, Subpart H source asses.s111ent (HNF-1974} calculate.d the unabated offsite dose for WES°F at 2.1 IE+O I mrem/year. The updated calculation places the unabated offsite dose at L38E+ol mrem/year: a change due to updated dose factors B!)d decay corrected inventory va_lues. After completion of tile s_tabilizaticiil activiiies the unabated offsite dose is calcula_ted to be 2.92E-04 mrem/yelll" res:ulting in the classification ofth:e WESF emission unit as.a minor source .

. .

·Describe then~ applicable requirements t!J.at will apply as a result ~Hhe change:· · (To be orovided in the ru,encv;annroval order.) .. ·--· The NOCA contains the proposediequirements .in .greater detail, but these are sununaiiiea below:

• The use of contamination control struc1:ures with HEP A filtered portable eidiausters to perforqi the construction and stabjlization activities associated with the W-130 Project.

• The use of a continuous air ni<Jnitot (CAM) for near real time monitoring ofpointsource emissions that have a calculated PTE in excess of five (5) mrem/ye_ar (U11til completion ofth.e stabilization activities.) These point sources are identjfled as Hot Cell D& E, the K3 Filter Pit groutingpoitable exhauster and the 296-B-IO stack.

... . . . . .

t,

• Alternate monitoring i:n~th09s are approved for use for the continuous and PCM monitoring requirei:ne,n1:s.

• The common stack (Kl & K3 or K3N) effluent monitoring system is operated under the altematiye sampling system method approved by USEPA (OAQ, 107 AUG 12, 1999) and WDOH (AIR-99°501). ·

•

•

For portable exha:usters,.at least daily or upon completion of the construction activity, smears do\Viistteam of the portable eidia_uster HEPA filtration will be 1*~n. If removable contamination is found above 1000 dpm/1Mcm2 bej:a/gamiita downstream of the el'.iliJ!u.ster HEPA filter, the source of the down!ltream coqtamination will be invl?stigated aitd corrected. In addition a ncm-des:tructive assay (NOA) will be p~rfori:ned .oil the filter media whe11ever the filt\lf is replaced or upon completion of the construction activity and thi: emissions will be back calculated by applying the demonstrated filter Iealc_ t~~ efficiency to the analytical results.

To verify continued l_ow diffus_e and fugitive emissions fyom the ventilation construction activity, the near facility monitoring (NFM) ne~ork data for stations N481, N532, N976 and N973 will be trended on a mmith)y b_asis until the construction a~tivity is c:Oilipleted.

1 PurpOse The purpose of this environmental calculati~n is to provide.tlte methodology, assiliiiptions and calculation used to estimate !lie unabataj potential to emit (PTE) and Total Effective Dose Equivalent to the Maximally Exposed Individual (TEDE to the MEI) radionuclide airborne emissions associated with the WESF'Stack and containment struc_tffre u~ge during the ventilation upgrade and stabilimtion activities.

2 Background Upgnides to the WESF K3 ventilated air space are required to support stabilimtion (grouting) activities under the W-130 project (design document CHPRC-02430, Rev. 0). The existing K3 abatement system wifl be disco_nn~ fro11_1 the tj)nimon stack and replaced with the K3N abatement system .. The K3 filters,. ducting and WESF Hot Cells A through F will be stabi\.ized wi~ gr011t. In addition to the installation and us_e of the I{:3N abatem:COt system, construction and .stabilization activities outside of the K3 ventilation boundmy will require the use of tempormy contamination contro_l structures utilizing HEPA filtered exhausters. The KJ abatement system ventilates the capsule storage areas to provide heat and hydrogen removal. The capsule• lll"e sealed sources which makes the materia_I contained in them unavailable for release. Thlll'Cfore no contribution to the PTE from the Kl ventilated air space is included in the PTE calcillation. The PTE and associated dose value are part of the informa~on provided to Washington Department of Health (WDOH) as part of a license revision request to .construct the KJN abatenlent system and.stabilize the contamination found in K3 ventilation boundary. Tile design document CHPRC-02430, Rev. 0 provided PTE caJculations for the KJN abatement system installation and operation. Tile.beginning inventory values used in the CHPRC-02430 document were verifi~ against the source document (HNF-S0-WM-TI-733, Rev 5) and it was discovered that the inventory contained in the B Cell tarik bottoms bad not been included in the PTE calculations. Tllis information is included as Appendix A This calculation has included the B Cell Tank Bottom inventory as part of the total \YESF inventory,

3 Methodology The calculations herein use the annual possession quantity (APQ) method for inventory using the methodology contained in DOE-~20~29 RI Section 2.1.1. The sources of the standard factors used jlJ"C contained in the calculation table notes.

for the ION ventilation .calculation:

1. For .each location, the individual isotopic APQs(from Appendix A) are multiplied by the release fraction for either liquids or particulate solids or solids to obtain the PTE. (fable 1)

2. For each Iocati9n, the _resul)S from stq> I are multiplied by offsite and onsite dose per unit release factors from DOE/RL-2006,:29 RI Table 4.7 (< 40 meters) to obtain the unabated TEDE to the onsite and offsite MEL (Table 2)

3. For each iocation, the abated TEDE to the offsite and onsite MEI is calculated by lllUltiplying the step 2 results by 0.01 (99% minimum HEPA filter removal efficiency). (Table 3)

The total for each locations' TEDE to the MEI for onsite and offsite abated dose is summed and the offsite TEDE to the MEI values is used as the value for the proposed emission limits during stab{lizatjon 8l_1d post-stabflization for inclusion in the FF-0 I license.

For the use of contamination coritri>I structures with HEP A filtered exhaust calc:ulation:

1


1. For each location, the APQs from Table 1 is multiplied by the release fraction for liquids or particulate solids, or solids to obtain the total PTE (Table 4).

2, For

a. The K3N abatement system tje-in to th_e common.stack and K3 Di,ict, the total of the results from step I are multiplied by offsite and onsite dose per unit releasefactors from DOE/RL-2006-29 R_i Table 4,7 (< 40 meters) and appliesa HEPA tilter leakage factor of0.01 (99% minimum leak test result) that credits the upstreamK3 HEPA filters for th_eir removal efficiency to calculate the unabated TEDE to the onsite and offsite MEI (Table 5) for the fali(s) aild duct removal downstream of the K3 HEPA filters or;

b, The K3 Filter Pit·stabilizaticin the results from step 1 are multiplied by offsite and onsite dose per unit rel~e factors from DOE/RL-2006-29 R.l Table 4_.7 (< 40 met_ers) to obtain the unabated TEDE to the oilsite and offsite MEI (Table 6).

3. For each location, the abated TEDE to the offsite and onsite MEI is calculated by multiplying the step I results by 0_ .. 01 (99% minimum ~PA fil~ ret11_oval efµcien~y). (Table7)

The total for each locations' TEDE to the MEI for orisite and offsite abated dose is summed and the offsite TEDE to the MEI values is used as the value for the proposed emission limit for inclusion in the FF-01 license.

4 Assumptions an~ Inputs The isotopic inventory APQ was obtained using inputs from CHPRC0 02430, Rev A K~JN Potential lo Emit C.alculations and BNP-SD-WM-TI-733, Rev 5, Support!ng Ca_lculations and Assumptions for Use in WESF Safety Analysis for the current Hot Cell and duct inventory. For the K3 duct, the isotopic split between Sr-90.and Cs-137 is Ul)known, therefore an equal d_istribution (50-50) w:as assumed. The extreme inventory values for each radionuclide was assumed to contribute fifty (50) peri:entofthe inven_tory va_luefor the duct. For the K3N calculated PTE, the Hot Cell inventories are assumed to be in particulate form and the K3 duct and B Cell Tank bottom inventory is assumed to be in solid form (HNF-197 4, 2002, Radionuclide National Emissions Standards for Hazardous Air Po{/IJ1an!s Potential-to-Emit Assessment, Revision J). For the K3N duct tie -in and K3 Filter Pit grouting calculated PTE, the Hot Cell inventories and the K3 duct inventory are assumed to be in particulate. form to reflect an increased potentiitl to disturb material located"in the K3 Duct from core dri1ling and provide a higher operating limit for containment structure use. The B Cell Tank Bottoms are assumed to be in a solid form and unlikely to be disturbed by the core <hilling actiyity; All calculations use the Off site and Onsite MEi with a release height of Jess than forty ( 40) meters.

The entire inventory of each location is assumed to be available for release at one time. For the K3N duct tie-in c~it is tal<;en for the .K3 abatement system HEPA filters as the filters will be in pl_ace dwing the fan removal. A ninety-nine pen:ent (99%) removal efficiency is credited to the HEPA filters to account for possible degradation from previous filter wetting inSctead of a ninety-nine po~ nine seven percent (99.97%) removal efficiency. In addition a HEPA filter leakage factor of ninety-nine percent (99% [ 1 % instead of the 0.05% requirement]) i_s applied for grouting activi~ies where the HEPA filter is in place but not pressurized (e.g. K3 Filter Pit} to account for minor seal leakage since the previous leak test. The K3 Filter Pit grouting requires that a filler and exhaust port be core drilled into each of the sectioliil of the K3

2


Filter Pit structure and therefore no credit for the in-place HEP A filters is t;lken. All this lends conservatism to the calculatic,n to assis~ in planning for adequate controls during the construction and stabllizati.on.activities.

5 Software Applications An Microsoft EXCEL• spreadsheet was used to calculate the PTE and TEDE to MEI values.

6 Calculation The calculati<>n i,s p~ntedin Tables I, 2, 3, 4, .5, 6 and 7 using the steps defmed in the Methodology.

It has been at least ten years since the invcnloiy_eslimal"5 were developed for the WESF K-3 exhaust duct and hot cells. Because 117Cs and ~'Sr have relatively short half-lives, these valucs are. being decayed to retlci:t a current inventory estimate.

l'er your request, the Washington State·Departrnent of Health (WDOt,t) grants a conditional,approval, as described'in Washington Administrative-Code (WAC) 246-247-60(1)(d), to.begin construction,activities associated with replacemenHn-kind of the WESF K3:abatement system. The allowed activities are identified in ,phase one. in the WESF;Notice:of Construction (NOC),application. Those-activities-are:

• The installation.of utilities infrastructure and concrete work for the,placement ofthe.K3N·abatement system; • Core.drilllng·ofthe.,ruck Port wallwill.be,performed to allow the exterior K3N abatementsystem inlet ducting to connect to,the,K3 Canyon exhaust

duct; and • Placement of the K3N abatement:system and· ducting up to the point of tie-in to the K3 Canyon duct, • HEPA filtered portable exhausters, heaters and the,associated"fixed head samplers will be Installed oh one inlet ductof,each Hof Cell. These units may be

tested but'not operated continuously prior to the time the K3 exhaust system is shutdown to allow the,K3N abatement system to be tied into the common stack and the K3 Canyon:exhaust duct.

If, for•any re;ison, themetcontamination identified during-construction for the.general area is,greater than 200 dpm/probe,area alpha,or:greater than 500,000 dpm/probe area:betacgamma,.you must stop work, notify Environmental, Radcon, and'WDOH and implement the controls listed below. Once:notifications1have been made and the following controls irnplemented,,excavation may continue: ·

• · Soil shall be wetted prior to excavation, if not already damp; • General area workplace air monitoring,shall be performed' during excavaiion activities; • Excavation and contaminated soil piles wiffbe-covered with plastic, or fixative applied at the-end of each shift, and/or as necessary to

prevent airborne-dust ,particles; and • Contaminated soil containing >500;000 dpm per probe area beta-gamma or >200 dpm/probe•area alpha will be-containerized or covered'with

clean fill ifit is to be left for greater than 48 hours,

This AlARACT will.expireiuponJssuance,of the,final license·for WESF or on March 30, 2016, whichever ls•sooneL . . . .

Fourth in table 5 which the contractors did not add as a footnote that only 99% efficiency was

used for the fifte_rs because of the break through caused by the grouting process.

Discussed issues with the NOA procedure to be used for t_he n,ea~rement of fi_fters for the_

portable exhausters.

Tad asked what spec_ificaffy DOH wanted for documentation on the NOA procedure and

n,easuring il'.lstru_mentilt_ion used. Do we want the calibration protocol used; calibration

instrumentation; whether if 1:he filters-are me11sured in pfa~e or in a testi_ng fa~ility. tad

The paired combination of the Kl and K3 or the Kl and K3N abatement systems exhaust through a common stack that is continuously sampled when the abatement systems are in operation. The historic activities with the exception of capsllle storage as detaillld in previous NO<;As are.no longer ~onducted at tl,e WESF Facility and the n.,.,v activities described b<!low will be c:onducted for stabilization activi_ties. After stabilization activities have been completed, routine operations and surveillance activities will continue for those portions of the facility associated with the storage and management of the capsules. Continuous operations <if the Waste Encapsulation and-Storage Facili.ty (WESF) consist of routine activities performed at WESF include but are not l!inited to:

A.Surveillances and inspections of the facility and stored material (e,g., capsule inspection).

B.Maintenance and repair activities.

C.Movement a_nii/or tra_hsPQrt of ~psllles or wast.e within the fi:1cilit'y or to another licensed storage facility.

· D.Continuous operation of liquid low .level radioactive (LLLW) stream piping. The tank TK 100 serves as a catch tank for liquid low level radioactive waste streams originating from WESF prior to stabilization, condensate from the K-1 and K-3N filters,-and the 296-B-I0 stack. TK-100 is vendlated through the WESF K-3N ventilation system and out of the 296-B-i0 St_a_c_~. - · · - ·

The contents ofTK-100 are emptied by pumping the LLLW to a tanker iruckat the Truck Load Out Port In the event that.additional storage capacity is needed, a new portable aboveground storage tank (nominal capacity of4,000 gallons) will be installed at the Truck Load Out Port and vented to TK-100 during filling operations. After filling the portable aboveground storage tank, the tank. will be ciisconni:cted from the Truck Load Out Port, a HEPA or NucFil ±X!ter s_hall be installed, arid then the tank will be riioved outside for storage uhtil arrangements are made to dispose of the excess LLL W. During normal operations the LL.LW streams to TK-100 are less than 0.001 curie/liter ofSr-90 and Cs0 !37. In the event that.the TK-100 contents are greater than or equal to 0.00 I curie/liter ofSr-90 and Cs-137 during routine operations, a WESF Ion Exchange Module will be installed at the Truck Load~! Port.and the contents ofTK-100 will be recirculated thrnugh the WESF!on ):lxc_harige Mod11.le l!n_t_i_l the concelltra_tion is less than 0.001 cllri~iter ofSr-90 a11d es-137. The WESF Ion Exchange Module will be v.erited to TK-100 during recirc_ulatio_n. Storage of the WESF Ion Exchange Module will normally be outdoors and will vent to atmosphere through a HEPA or NucFil filter. Use of the WESF Ion Exchange Module will continue up to a maximum loading ofZ0,000 curies of Sr-90 or 25,000 curies of Cs-I 37. · In addition,.subject to additional conditions and limitations provided herein, this lipproval also extends to one time construction and stabilization activities associated wit,h the W~ Liii WE_S°FStab{I_i_z;ition Proje_ct (W-130 Project).
