The Sodium Reactor Experiment in Santa Susana Field Laboratory was an experimental nuclear reactor that operated from 1957 to 1964 and was the first commercial power plant in the world to experience a core meltdown in July 1959.
Stationary Low-Power Reactor Number One, also known as SL-1, initially the Argonne Low Power Reactor (ALPR), was a United States Army experimental nuclear reactor in the western United States at the National Reactor Testing Station (NRTS) in Idaho about forty miles (65 km) west of Idaho Falls, now the Idaho National Laboratory.
The plant with seven units is the largest single nuclear power station in the world, which now again is shut down due to the Fukushima accident. [46] 0: 1 Dec 2009: Hamaoka, Japan: Leakage accident of radioactive water. 34 workers were exposed to radiation: 0: Mar 2011: Fukushima Dai-ichi, Japan: The world's second INES 7 accident.
The world's first nuclear reactor meltdown was the NRX reactor at Chalk River Laboratories, Ontario, Canada in 1952. [22] The worst nuclear accident to date is the Chernobyl disaster which occurred in 1986 in the Ukrainian SSR, now Ukraine. The accident killed approximately 30 people directly [23] and damaged approximately $7 billion of property.
Hanford’s historic B Reactor, the world’s first full-scale nuclear reactor, went critical on Sept. 26, 1944. Wigner’s team had designed the Hanford reactors to house 1,600 process tubes.
On July 12, 1957 the Sodium Reactor Experiment became the first nuclear reactor in California to produce electrical power for a commercial power grid by powering the nearby city of Moorpark. [ 1 ] [ 2 ] In July 1959, the reactor experienced a partial meltdown when 13 of the reactor's 43 fuel elements partially melted, and radioactive gas was ...
From 1957 (when the first nuclear reactor in the United States began operations) through TMI's partial meltdown, only one other accident occurred: the Argonne explosion of 1961, which killed three ...
Last month, the plant made its first drone flight into the worst-hit reactor, No. 1 reactor, to investigate the melted debris, but had to cancel a second day of exploration after a secondary robot ...
