Part of the Army Nuclear Power Program, SL-1 was a prototype for reactors intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line. [9] The design power was 3 MW , [10] but some 4.7 MW tests had been performed in the months before the accident.
The SL-1 was designed by the Argonne National Laboratory to gain experience in boiling water reactor operations, develop performance characteristics, train military crews, and test components. Combustion Engineering was awarded a contract by the AEC to operate the SL-1 and in turn employed the Army's military operating crew to continue running ...
The tests proved key safety principles of the design of modern nuclear power reactors. Design power of BORAX-I was 1.4 megawatts thermal. The BORAX-I design was a precursor to the SL-1 plant, which began operations nearby in 1958. The principles discovered in the BORAX-I experiments helped scientists understand the fatal meltdown at SL-1 in ...
During a maintenance shutdown, the SL-1 experimental nuclear reactor underwent a prompt critical reaction causing core materials to explosively vaporize. Water hammer estimated at 10,000 pounds per square inch (69,000 kPa) struck the top of the reactor vessel propelling the entire reactor vessel upwards over 9 feet (2.7 m) in the air. One ...
An experimental reactor called SL-1 (Stationary Low-Power Plant Number 1) was destroyed when a control rod was pulled too far out of the reactor, leading to a near-instantaneous prompt-critical power excursion and steam explosion. The reactor vessel jumped up 9 feet 1 inch (2.77 m). [62]
WR-1 Reactor at Pinawa, Manitoba, Canada: LOCA loss of coolant accident. 2,739 litres of coolant oil leaked, most of it into the Winnipeg River. The repair took several weeks for workers to complete. [22] 0: Unknown August 1, 1983: Pickering nuclear Reactor 2, Pickering, Ontario, Canada: LOCA loss of coolant accident.
Called Hermes, Kairos Power's low-power demonstration reactor will show the company's capability to deliver low-cost nuclear heat and is scheduled to be operational in 2026, officials said.
Nuclear reactors line the riverbank at the Hanford Site along the Columbia River in January 1960. This image of the core from the SL-1 disaster, Idaho Falls, Idaho, USA, served as a reminder of the necessity for proper reactor practice and safeguards.
