D&D Sampling and Analysis

• Analytical support for characterization of facility contents and construction debris

• K-25 slab, K-27, and K-31 are currently underway

• Other facilities are expected to be shifted to scope as these are completed

• 3000 analyses performed in FY14 • Total cost for analytical services ~$600K

Landfill Operations

• Environmental Management Waste Management Facility (EMWMF)– CERCLA waste associated with

the ORR– Must meet WAC requirements

• Oak Ridge Reservation (ORR) Landfill – (formerly the Y-12 Sanitary Landfill)– Disposal of sanitary, industrial,

construction, and demolition waste

EMWMF and ORR Landfill Sampling and Analysis

• Sample Locations– Monitoring wells– Contact Water– Leachate– Air Sampling

• Number of analyses per year is relatively constant– Weekly, Quarterly, Semi-annual, Rainfall event driven (EMWMF)– Dynamic analytical suite for the EMWMF

• 8000 analyses performed in FY14• Total cost for analytical services $1.2M

Water Quality and Environmental Compliance

8

Water Quality and Environmental Compliance Sampling and Analysis

9

• Samples– Groundwater– Surface Water– Outfalls– Runoff– Air Monitoring

• Annual sampling for Water Quality is relatively constant

• Environmental Compliance varies some, but overall is constant

• 21,000 analyses performed in FY14• Total cost for analytical services $1.4M

Waste Management and Disposition

10

• UCOR has taken a proactive and aggressive approach to waste management

• Waste is characterized and shipped as it is generated

• The majority of legacy waste has been dispositioned

• 1400 analyses performed on waste materials in FY14

• Total cost for analytical services $175K

Y-12 Outfall 200 Treatability Study and Conceptual Design

Outfall 200 at right; Flow Augmentation at left

Mercury Treatment Facility at Outfall 200

• UCOR has performed treatability studies in support of the conceptual design report.

• Pre-design studies are now underway.• Anticipated construction beginning in 2017• Operations starting in 2020. • The proposed facility can treat 1,500 gallons of water per minute.• The treatment facility will be NPDES permitted

12

Site Remediation

• Expected increase in soil samples from the ETTP site• Driven by the Zone 1 and Zone 2 Records of Decision

(RODs)• Some will be associated with land transfers and footprint

reduction• Will require very low reporting levels in some cases

depending on final disposition of parcel• ~$10K spent on remediation in FY 2014

13

Bioassay and Industrial Hygiene

• Bioassay Program– 2500 analyses– $250K– Will see a decrease in FT 2015 due to changes in program

requirements

• Industrial Hygiene Program– 2600 analyses– $225K– Expected to remain relatively constant through 2015

Analytical Support Summary

• Analytical laboratories performed over 38,000 analyses in support of UCOR projects in FY 2014

• The total cost for analytical services in FY 2014 was ~$4M • FY 2015 analytical support is expected to remain largely unchanged

– New D&D characterization projects are expected to be added to the current scope as K-27 and K-31 are completed

– Landfill, Water Quality, and Environmental Compliance Program needs are expected to remain constant

– Analytical needs for waste characterization associated with the Waste Disposition Program are expected to decrease about 15-20%

– Bioassay requirements are expected to decline approximately 50%– Industrial Hygiene sampling is expected to remain constant

K-25 Retrospective

22

The “U” was the first stage of the K-25 Plant. It came online in 1945.

K-25 Retrospective

• The K-25 building was 4 stories high and almost a half mile long.• The building enclosed some 2 million square feet of space, making

it the largest building in the world at the time. • The final stages of the plant did not come on line until mid-August

1945. • Maximum enrichment during the war was about 20%. • The eventual cost of the K-25 complex would be over $500 million.• Even though the plant was fully automated, 9,000 employees

working in three shifts were needed to operate the plant.

23

K-25 Retrospective

• Because the uranium hexafluoride gas which was pumped through the building attacked grease, new pump seals had to be developed that were both gas tight and greaseless. The new seal material developed came to be known after the war as Teflon.

• In April 1945, a second gaseous diffusion plant, K-27, was started. It would come on line in January 1946 and make all of the other uranium separation processes obsolete.

• After the war additional gaseous diffusion buildings were built to increase production of enriched uranium (K-29, K-31, K-33).

• The original K-25/K-27 facility was shut down in 1964 after operating without error for 20 years.

• The rest of the gaseous diffusion plant was shut down in 1987.

• UCOR completed demolition of the K-25 facility in June 2014

• 6 months ahead of schedule

• DOE realized a cost savings of ~$225M from the early completion

• Slab characterization is underway
