  1. Cleanup Progress UpdateRichland Operations Office September 2014

  2. Richland Cleanup Priorities • Maintain safe, secure and compliant activities, facilities and operations • Continue River Corridor cleanup, including remediation of 618-10 Burial Ground • Continue Plutonium Finishing Plant deactivation, decommissioning and demolition • Continue groundwater pump and treat operations, and implement additional groundwater remedies

  3. Richland Cleanup Priorities • Continue preparations for 324 waste site soil remediation (River Corridor) • Move sludge from K-West Basin near the Columbia River to interim storage in the Central Plateau • Move cesium, strontium capsules stored underwater in Waste Encapsulation Storage Facility into dry storage

  4. 415 of 522 facilities in the River Corridor have been demolished River Corridor Building Demolition

  5. River Corridor Waste Site Remediation 887 of 1,012 waste sites in the River Corridor have been remediated

  6. River Corridor 300 Area Progress 1977 For nearly 60 years, the 300 Area was the center of Hanford’s radiological research and fuel fabrication. Now the above ground field work and building demolition is nearly complete. Before 2014 After

  7. River Corridor Progress in 300 Area 309 Plutonium Recycle Test Reactor (PRTR) The 1,082-ton PRTR was lifted and transported to the Environmental Restoration Disposal Facility (ERDF) for disposal. Workers removed hundreds of contaminated process tubes and pipes to support the removal of the reactor. A lift system was constructed beneath the vault 340 Tank Vault The 1,153-ton vault was transported to ERDF for disposal

  8. River Corridor Progress in 100-B/C Area Field remediation near C Reactor Excavation at the 100-C-7 chrome waste site reached groundwater at 85 feet Excavation and backfill are complete at waste sites near B and C Reactors

  9. River Corridor Progress in D Reactor Area 2009 Demolition of water filter building near D Reactor 2014 Chromium excavation near D Reactor reached groundwater – 85 feet deep

  10. K-Basin Closure Project • Completed installation of structural steel on K-West Annex • Completed first set of modifications to K-West Basin to allow for installation of sludge removal system • Initiated procurement of process equipment for sludge removal Workers install metal wall panels on the K-West Annex. The Annex will house equipment used to transfer radioactive sludge in the K West Basin to a facility on the Central Plateau.

  11. 100-N Area N Reactor - 2012 Before N Reactor - 1970 After

  12. River Corridor Progress in N Reactor Area Load out of contamination at 100-N area Concrete anchor blocks were removed from the site of a former pump house on the Columbia River near N Reactor. Demolition of the 100-N Fuel Storage Basin

  13. River Corridor Progress in 100-D and H Areas Field remediation near D Reactor Field remediation near H Reactor Waste site remediation at H Reactor Area

  14. 100-F Area F Reactor Area during operations F Area in 2012

  15. 618-10 Burial Ground Remediation Progress The 618-10 Burial Ground operated from 1954 to 1963. It covers approximately 5.2 acres, and contains 12 trenches and 94 vertical pipe units. Remediation of trenches is scheduled for completion in 2015. Methods testing for removal of the vertical pipe units at 618-10 Burial Ground is under way

  16. 16.4 million tons of waste disposed since ERDF opened in 1996 1 million tons of waste disposed in fiscal year 2014 Environmental Restoration Disposal Facility Waste transport drivers have logged millions of miles since ERDF opened in 1996. Workers dispose the 340 Vault earlier this year

  17. Central Plateau Cleanup Plutonium Finishing Plant Workers are removing glove boxes and pencil tanks at the high-hazard Plutonium Finishing Plant. Deactivation at the plant is almost 75 percent complete.

  18. Cleanup Progress at Plutonium Finishing Plant • In recent weeks, crews demolished 8 support buildings, clearing the way for operating heavy equipment and staging debris during demolition of main plant • 63 of 81 plant facilities removed or demolished • 212 of 238 glove boxes removed or cleaned out for removal during demolition • 142 of 196 pencil tank units removed The 270-Z Building housed the plant’s administration offices, one of eight support facilities removed or demolished this summer. Preparing to enter one of Hanford’s most hazardous rooms: Workers helped select protective equipment and suits for entering the plant’s McCluskey Room this fall.

  19. Central Plateau Cleanup There are hundreds of facilities to be cleaned out and torn down, including 5 large chemical processing canyons Cesium and Strontium Capsules Nearly 2,000 capsules of highly radioactive cesium and strontium need to be moved out of a storage pool into dry storage PUREX Canyon

  20. Groundwater Remediation Progress • Contractor recently met DOE annual goal to remove 550 pounds of hexavalent chromium from groundwater near Columbia River 4 months ahead of schedule • More than 1 billion gallons treated and 680 pounds removed in FY14 through end of July • Remediation of major sources of chromium in soil and operation of five pump-and-treat systems along river is reducing contaminant concentrations in groundwater Aerial view of 100-D Area Inside a pump-and-treat system at 100-D Area

  21. Hanford Site Services • Providing critical infrastructure services to • Richland Operations Office • Office of River Protection • 5 other prime contractors • Maintaining and consolidating site infrastructure and site-wide systems • Ensuring 45 to 65 year old infrastructure has the capacity and reliability to support the cleanup mission • Providing reliable services to ensure protection and safety of nuclear facilities • Aligning services to support changing cleanup needs There are over 6,000 electrical poles delivering power across the site Water lines were installed in the 40s and 50s

  22. Complexity of Scope • Water Systems • Over 95 miles of buried pipe • 800M gallons of water used annually • Electrical Utilities • 246 miles of power lines • 6,000 power poles • Loads will double with Waste Treatment Plant • Emergency Services & Systems • Radio Fire Alarm Reporting is essential to employee welfare and the safety and security of facilities and Information Technology • Legacy applications to be updated • Cyber security improvements • Roads • Over 5,700 passenger vehicles (daily average) • 350+ lane miles of paved roads • 500 trips by heavy haul trucks (daily average) Reliable infrastructure services are necessary for Hanford cleanup operations Hanford has over 350 lane miles of roads
