Plutonium Finishing Plant Demolition
Marks the End of an Era
The 580-square-mile Hanford Site in southeastern Washington state was created in 1943 as part of the Manhattan Project to produce plutonium for the nation’s defense program. The Plutonium Finishing Plant, also known as PFP, played a critical role in Hanford’s mission, representing the last stop for plutonium production during nearly 40 years of operations at the Site. But the nature of the work performed also left the Plant as one of the Site’s most hazardous buildings after production ended in 1989.
In 2020, after nearly two decades of cleanout and preparation, workers celebrated completion of demolition of the PFP Main Processing Facility. In the coming months, work will continue on removal of Plutonium Reclamation Facility rubble, core sampling of soil and covering the building slabs with a soil cover. The safe progress of this complex project is a testament to a talented and dedicated workforce, as well as excellent collaboration between labor unions, management, the Department of Energy and the regulatory agencies.
