224:, began in January 2017 and was completed in March 2017. Demolition of the third remaining major facility, the ventilation stack and fan house, was completed in July 2017. Demolition of the last of four major remaining facilities, the Main Processing Facility, began in July 2017. As of December 2017, all demolition is on hold, after contamination was found as far away as 10 miles from the site, and found in two car air filters that were checked by a Hanford contractor and deemed clean, but rechecked by an independent lab and were found to have small amounts of radioactive contamination. All demolition and cleanup work was completed in November 2021.

That preparatory work has been called the most hazardous cleanup work at the Hanford Site and PFP has been called Hanford's most hazardous building.
207:
Before the last four major facilities at the plant could be demolished, approximately 20 years of work was completed to stabilize approximately 20 tons (nearly 18 metric tons) of plutonium-bearing material by 2004; remove legacy plutonium from plant systems by 2005; ship all weapons-grade plutonium

The
Department of Energy's PFP Closure Project intended to have the entire facility cleaned and destroyed down to a concrete slab in 2017, with all contaminated materials moved to other sites. Open-air demolition of the plant's last four remaining major facilities began in November 2016 on the
285:"From 1949 to 1989, U.S. Department of Energy contractors operated the Plutonium Finishing Plant (PFP) to process plutonium nitrate solutions into a solid form (hockey puck-sized “buttons” or oxide powder) for shipment to the nation’s weapons production facilities."

The plant began in 1949 with the purpose of on-site production of plutonium metal in a form suitable for weapons at
Hanford. It also participated in programs to recycle plutonium. One of the projects was the use of
49:(FFTF). For that project, one of the PFP's tasks was to perform quality assurance for the fuel pins that had been constructed for the FFTF by outside vendors, such as
