SUBJECT: THREE MILE ISLAND TATION \dUNIT NO. 1DOCKET NO. 50-289

Enclosed please find 3 originals and 37 copies of information requestedin your October 13, 1976 letter concerning the Three Mile Island Unit 1Appendix I submittal. We have responded to all questions except the request tocalculate annual total body man-rem and annual man thyroid rem received by theU.S. population. It is our opinion that this type of information is not requiredby Appendix I since the guidance provided suggests that man-rem doses be calcu-laced for the 50-mile population only.

The NRC has performed similar calculations for the Three Mile Island Unit 2plant and has published this information in Table 5.7 of the Final EnvironmentalStatement dated Dece=ber, 1976. TMI Units 1 and 2 are essentially identical and,therefore, we expect the doses will be the same.

We trust that this additional information will be sufficient to allow theNRC to complete their review of the TMI-l Appendix I filing.

'l INcp Very truly yours,

THREE MILE ISLAND NUCLEAR GENERATING STATION LM T 1

DOCKET No. 50-289

RESPONSE TO REQUEST FOR ADDITIONAL IN70RMATION

Question #1: If there is a prior knowledge that the current 50 mile populationage distribution may be s.ignificantly different from the U.S.population distribution, then furnish the current age distributionof the 50 mile population (e.g. , 0-12, 12-18, >18).

Response: We have reviewed the infor=ation contained in the 1970 census dataand have concluded that the current 50 mile pop ation distributionis not significantly different from the U.S. population distribution.

Question #2: Provide data on annual = eat (kg/yr), = ilk (liter 3/yr) and truckfarming production (kg/yr) and distribution within a 50 mile radiusfrom the reactor. Provide the data by sectors in the sa=e :mnerindicated in Sections 2.1.3.1 and 2.1.3.2 of R. G. 4.2, Rev. 1.

Response: During our review of available data concerning the annual productionof meats, =11k, and prcduce, it was deter =ined that production ineach seg=ent of sectors SSE through NE were essentially the sa=e forall ite=s. The production in each seg=ent of sectors ENE through SEvere also essentially the sa=e but higher than that of the othersectors. The infor=ation contained in the attached tables indicatesthe total yield in each sector for the particular product indicatedat the top of the table.

2Question #3: Furnish information on type, quantity and yield (kg/m ) of irrigatedcrops grown.

Response: A study of downstream water users was conducted by our ArchitectEngineer in late 1967. This study showed no irrigation downstreamof the TMI-l site. A recent check of County Agricultural Agentsfailed to provide conclusive infor=ation since data of this sort isnot kept on file. In addition, the Susquehanna River- Basin Coc=ission,the Pennsylvania Crop Reporting Service, and the Pennsylvania Lepart-ment of Environmental Resources were contacted by telephone. In eachcase we were unable to determine if irrigation is done in the lowerSusquehanna River Basin. Therefore, there is inaufficient evidencato include irrigated crops in our analysis.

Question #4: Provide infor=ation on graaing season (give dates), feeding reg 1=esfor cattle (such as grazing practices, green chop feeding, corn andgrass sileage feeding and hay feeding) pasture grass density (kg/m')

2and yield statistics (kg/m ) for batvested forage crops for beef anddairy cattle feeding..

Response: As stated in our Appendix I submittal, the guidelines given inAppendix C of Regulatory Guide 1.109 were used to calculate radioactiveconcentrations in = ilk and = eat.

Question #5: Detersine and indicate in tabular for=at the present and projectedcoa =ercial fish and shellfish catch (in lbs/yr) from contiguouswaters within 50 =iles of the plant discharge. Report the catchby total landings and by principal species, indicating the relativeamounts used as hu=an food. Indicate the location of principalfishing areas and ports of landing associated with these contiguouswaters and relate these locations to harvest by species. Indicatethe relative a= cunts consu=ed locally. Determine and tabulate thepresent and projected recreational fish and shellfish harvest fromthese waters in the same for=at, also indicating principal fishingareas and their yield by species. As above, indicate the relativeamounts consu=ed locally. Include any harvest and use of seaweed,other aquatic life, or any vegetation used as hu=an fcod from thesewaters. Identify and describe any fish far=s or similar squaticactivity within the 50 mile area utilizing water that =ay reasonablybe affected by the power plant discharge. Indicate the species and*production from each of these faci.! ties and indicate the relativea=ounts consumed locally.

Response: Within 50 siles downstream of the TMI Nuclear Station discharge, nofish or shellfish are harvested from contiguous waters on a ce==ercialbasis. Eowever, approxi=ately 31,600 kg of fish are esti= aced to betaken annually from these waters by recreational fisher =en. Thisesti= ate was arrived at by extrapolating the results of the 1974 creelcensus, conducted by the Applicant's consultant Ichthological Associates,Inc., of the Susquehanna River in the vicinity of IMI Nuclear Station.The =ethodology behind this esti= ate assu=es that the recreationalfishing pressure and the species taken for 50 miles below the TMINuclear Station discharge are the sa=e as that esti=ated, from the1974 creel census, for the Susquehanna River in the vicinity of TMINuclear Station. The applicant believes the nethodo2cgy used isconservative.

Below is a list of fish species and yield per species esti=ated to betaken by recreational fisher:en within 50 =1les downstream of the TMINuclear Station discharge.

Catfisa 8200 kg

Rockbass 4468 kg

Sunfish 5609 kg

Smm11mnuth Bass 8423 kg

Crappies 1236 kg

Walleye 2805 kg 1484 026Other* 794 kg

* Other = Brown Trout, Muskellunge Carp, Qu111back, White Sucker,Northern Hog Sucker, Shorthead Sealhorse, Large=auch Bass,and Yellow Perch .

Question #6: Identify any additional exposure pathways specific to the regionaround the site which could contribute 10% or more to either indi-vidual or population doses.

Response: As stated in Sections 2.5.6 and 3.5.5 of the TMI-1 Appendix I submittal,there are no other pathways which would be likely to produce 10* ofthe dose calculated by the pathways described therein.

Question #7: Annual Population Doses - Calculate, using the infor=ation providedin response to questions 1-6 above and any other necessary supportingdata, the annual total-body man-res and the annual man-thyroid-remto the population expected to reside in the 50 mile region at themidpoint of plant operation as well as the annual total body =an-resand the annual man-chyroid-res received by the U.S. population atthe same time from all liquid and gaseous exposure pathways. Provideas an appendix to your response a description of the =odels andassumptions used in these calculations.

Response: Table 3-14 of the TMI-l Appendix I submittal contains annual 50 milepopulation dose infor=ation based on population projections for theyears 1980 and 2010. These dose calculations are based on the sa=edata we are providing in response to Questions 1 through 6.

The attached Table 7-1 lists the 1980 and 2010 50 mile population doses.As shown on this table, the increase in man-thyroid-rem and total-bodyman-rem between the years 1980 and 2010 is 2.1 and 1.0 man-res,respectively. Since the increase in dose is so s=all, we do not feelthat an additional calculation at the midpoint of plant operation vouldbe meaningful.
