Plutonium pit production was halted in 1989 after EPA and FBI agents raided the facility [5] and the plant was formally shut down in 1992. Rockwell then accepted a plea agreement for criminal violations of environmental law. [6]
After sufficient plutonium had been produced, the production reactors were shut down between 1964 and 1971. Many early safety procedures and waste disposal practices were inadequate, resulting in the release of significant amounts of radioactive materials into the air and the Columbia River, resulting in higher rates of cancer in the ...
The plant has since been shut down, with its buildings demolished and completely removed from the site. The Rocky Flats Plant was declared a Superfund site in 1989 and began its transformation to a cleanup site in February 1992. Removal of the plant and surface contamination was largely completed in the late 1990s and early 2000s.
BOMARC Site RW-01 is a 75-acre (30 ha) [1] fenced-off site contaminated primarily with "weapons-grade plutonium (WGP), highly-enriched and depleted uranium." On 7 June 1960 an explosion in a CIM-10 Bomarc missile fuel tank caused the accident and subsequent contamination.

The US space agency has routinely had to carry out commands to shut off various science instruments over the years as the 47-year-old spacecraft drains its supply of plutonium.
However, the N Cell worked fine, and the RMA line was shut down for good in 1984. The RMC line was restarted on 1 July 1985, and ran until October. After multiple repairs, it was reactivated in April 1986 and produced weapons-grade plutonium for the next six months. Another shut down for a series of upgrades and repairs followed.
The project's leaders also proposed a test run using plutonium fuel, however this was never carried out due to the project's cancellation. [19] Despite the project's apparent success, the MSRE was shut down in December 1969 due to pressure from Milton Shaw, the director of the AEC's Reactor Development and Testing Division. [20]
