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. [1]
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.
Apr. 25—Trace amounts of plutonium from decades of weapons work at Los Alamos National Laboratory have contaminated the Rio Grande at least as far as Cochiti Lake and could be in the regional ...
Soil, surface water, groundwater and air contamination by plutonium, americium, uranium and VOCs from nearly forty years of nuclear weapons manufacturing. The plant was closed after being raided by the Federal Bureau of Investigation and EPA. [21] 07/14/1989: 11/21/1989
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 ...
Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 is also used for that purpose. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233. Plutonium-239 has a half-life of 24,110 years. [1]
Saltcrete is the result and technique of wastewater processing and was the second-largest mixed waste stream at RFETS requiring treatment and disposition. The majority of wastewater from RFETS production processes is contained in large tanks and then is treated by precipitation, filtration, evaporation, and drying to result in a matrix referred to as "salts".
The plutonium, dissolved in an organic solvent, flowed into the center of the vortex. Due to a procedural error, the mixture contained 3.27 kg of plutonium, which reached criticality for about 200 microseconds. Kelley received 3,900 to 4,900 rad (36.385 to 45.715 Sv) according to later estimates.
