CH2M Hill Plateau Remediation Contract
324 Building Disposition Project

The U.S. Department of Energy and contractor CH2M HILL Plateau Remediation Company are safely and compliantly managing the 324 Building at the Hanford Site in southeast Washington state and remediating the associated highly contaminated waste site beneath the building.

The 324 Building operated from 1966 to 1996 and supported research involving highly radioactive materials.

The facility is located in Hanford's 300 Area, which was home to uranium fuel manufacturing operations and research facilities to support the Site's former mission of producing special nuclear materials for nuclear weapons production. Many of the contaminated buildings and much of the contaminated soil resulting from work conducted in the 300 Area have been cleaned up.

The 324 Building demolition operations were postponed in 2010 after workers discovered significant contamination under a portion of the building. Demolishing the building and cleaning up the waste site is a top priority to the U.S. Department of Energy (DOE) and CH2M HILL Plateau Remediation Company (CHPRC) due to the close proximity of the Columbia River and the City of Richland.

Today, CHPRC is safely and compliantly managing the building, proceeding with design, testing, procurement and construction activities to remove the highly contaminated soil allowing for the eventual demolition of the facility.

Project Facts

  • The contaminated soil is located beneath B Cell, a robust reinforced concrete structure within the 324 Building.
  • The contaminated soil is approximately 300 yards away from the Columbia River.
  • Workers will use remote-operated equipment, to be installed within the B Cell, to safely and compliantly excavate and dispose of the soil.
  • A short distance from the 324 Building, engineers constructed a full-scale replica of key areas of the facility.
