The Rocky Flats Plant was a United States manufacturing complex that produced nuclear weapons parts near Denver, Colorado. [2] The facility's primary mission was the fabrication of plutonium pits, [3] the fissionable part of a bomb that produces a nuclear explosion.
One of four example estimates of the plutonium (Pu-239) plume from the 1957 fire at the Rocky Flats nuclear weapons plant. The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries.

Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
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.
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
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 ...
Tell the whole story of plutonium’s use. Our entire region should be extremely proud of the B Reactor. A massive edifice, built in a year, under tight security.
Plutonium–gallium–cobalt alloy (PuCoGa 5) is an unconventional superconductor, showing superconductivity below 18.5 K, an order of magnitude higher than the highest between heavy fermion systems, and has large critical current. [46] [50] Plutonium–zirconium alloy can be used as nuclear fuel. [51]
