Plutonium Finishing Plant
The Plutonium Finishing Plant (PFP), also known as 'Z Plant', was part of the Hanford Site nuclear research complex in Washington, US.[1][2][3][4][5]

History
It began in 1949 with the purpose of helping Hanford make plutonium metal in a form suitable for weapons on-site.[1][2] It also participated in programs to recycle plutonium. One of the projects in this program was the use of mixed plutonium-oxide uranium-oxide (MOX) fuel in the Fast Flux Test Facility. One of the PFP's jobs was to quality assure the fuel pins that had been constructed for the FFTF by outside vendors, such as Kerr-McGee, NUMEC, and Babcock & Wilcox[1][5]
The PFP Closure Project intends to have the entire facility cleaned and destroyed down to a concrete slab by 2016, with all contaminated materials moved to other sites.[1]
Purposes
- Created plutonium 'buttons', used to make weapons, until 1989[1][2]
- Special nuclear material handling and storage
- Plutonium recovery
- Plutonium conversion
- Laboratory support
- Waste handling
- Shutdown and operational facility surveillances.[2]
Divisions
Plutonium Conversion Facility
- 'Remote Mechanical A' line - created plutonium oxide powder
- 'Remote Mechanical C' line - created metallic plutonium from plutonium nitrate[2]
Plutonium Reclamation Facility
- Produced 'high purity plutonium nitrate solution' from a 'variety of feed sources, including scrap'.[2] Started in 1964 [4]
Waste Treatment Facility
Incinerator
- Burned old clothes, filters, etc. to recover plutonium residue [3]
Other
- Ventilation systems, nuclear storage vaults, chemical storage, office space, backup generator, etc.[2]
- RECUPLEX process, Plutonium recovery and recycle. Contaminated the ground with plutonium, carbon tetrachloride, and acidic waste[4]
