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.
After the fire, plutonium was detected near a school 12 miles (19 km) away and around Denver 17 miles (27 km) away. An independent group of scientists conducting off-site testing 13 years later found plutonium contamination in areas in nearby Rocky Flats to be 400 to 1,500 times higher than normal, higher than any ever recorded near any urban ...
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 ...
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 ...
A criticality accident occurred on December 30, 1958, at Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico, in the United States It is one of 60 known criticality events that have occurred globally outside the controlled conditions of a nuclear reactor or test; though it was the third such event that took place in 1958 after events on June 16 [1] at the Y-12 Plant in Oak Ridge ...
Karen Gay Silkwood was born in 1946 in Longview, Texas, and raised in Nederland, Texas.She lived with her mother Merle, father Bill, and sisters Rosemary and Linda. [1] In high school, Karen was a straight 'A' student and a member of the National Honor Society.
The Kyshtym disaster, (Russian: Кыштымская авария), sometimes referred to as the Mayak disaster or Ozyorsk disaster in newer sources, was a radioactive contamination accident that occurred on 29 September 1957 at Mayak, a plutonium reprocessing production plant for nuclear weapons located in the closed city of Chelyabinsk-40 (now Ozyorsk) in Chelyabinsk Oblast, Russia in the ...
The "Thin Man" design was an early nuclear weapon design proposed before plutonium had been successfully bred in a nuclear reactor from the irradiation of uranium-238. It was assumed that plutonium, like uranium-235, could be assembled into a critical mass by a gun-type method, which
