Workers with Hanford Field Office contractor Central Plateau Cleanup Company recently demolished a long-serving mobile office complex near the Columbia River. The effort is part of a broader push to remove or relocate outdated facilities near the former K East and K West reactors.
RICHLAND, Wash. – A large office complex that served as a hub for Hanford cleanup efforts for more than 20 years has been torn down as part of the site's ongoing risk-reduction work.
The complex, made up of 16 single-wide trailers, stood near the Columbia River in Hanford’s 100K Area. It was one of the largest mobile structures in the 580-square-mile site and supported hundreds of engineers, planners and project staff since 2000.
Its removal marks another step in a broader effort to clean up and modernize areas no longer needed to support active work. Demolishing the trailers clears the way for continued progress near the former K East and K West reactors.
Over the years, staff based in the complex led major cleanup projects, including cocooning of the K East Reactor and removing radioactive sludge from the K West Reactor's spent fuel basin. The basin was drained and stabilized last summer.
