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.
EBR-I's construction started in late 1949. The reactor was designed and built by a team led by Walter Zinn at the Idaho site of the Argonne National Laboratory, [6] known as Argonne-West (since 2005 part of Idaho National Laboratory). In its early stages, the reactor plant was referred to as Chicago Pile 4 (CP-4) and Zinn's Infernal Pile . [7]
President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. [3] This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the ...
The river starts in the Rocky Mountains and flows in a generally southeast direction into the Snake River Plain. True to its name, the Big Lost River's surface flow does not reach any larger river but vanishes into the Snake River Aquifer at the Big Lost River Sinks, giving the river its name. [2] The river is one of the Lost streams of Idaho ...
Arco is located along the Big Lost River [10] and is a gateway to the Lost River Range from the Snake River Plain. Craters of the Moon National Monument is located along U.S. Route 20, southwest of the city. The Idaho National Laboratory (INL) is located east of Arco.
In 1975, the United States Atomic Energy Commission (AEC) was divided into the Energy Research and Development Administration (ERDA) and the Nuclear Regulatory Commission (NRC). The Idaho site was renamed the Idaho National Engineering Laboratory (INEL) in 1974. After two decades as INEL, the name was changed again to the Idaho National ...
Since 1951, fifty-two reactors have been built on the grounds of what was originally the Atomic Energy Commission's National Reactor Testing Station, currently the location of the U.S. Department of Energy's Idaho National Laboratory (INL). Constructed in 1967, the ATR is the second-oldest of three reactors still in operation at the site. [2]
This map strongly suggests that there are some state-specific differences in reporting. From 1951 – 1962, the Nevada Test Site (NTS) was a primary site used for both surface and above-ground nuclear testing, with 100 tests at or above ground level, all of which involved releases of significant amounts of radioactive material into the atmosphere.
