For nearly 40 years, the Rocky Flats Plant was a key part of the Federal government's nationwide complex for nuclear weapons research, development, and production. Rocky Flats provided unique processing capabilities for the fabrication of weapons components from plutonium, uranium, beryllium, and stainless steel. The Rocky Flats nuclear production
mission was curtailed in 1989. The Rocky Flats Environmental Technology Site (RFETS) is situated on a 6,262 acre reserve (10.2 square miles) located 16 miles northwest of
Denver, Colorado. The portion of the site where facilities are located and work is performed consists of 384 acres and has controlled access. The remaining 10 square miles serves as a buffer zone.
