29: 299: 180:). It was restarted in May 1950 and operated until 1954. The reactor was authorized to operate up to 300 kilowatts. The two versions of the reactor were used to study physics, separate fission products, recover tritium from irradiated lithium, and study radionuclide metabolism in laboratory animals. 187:. Pipes, valves, and building debris were placed in the reactor's containment shell, which was then filled with concrete. The 800-short-ton (730 t) shell was buried on the site in a 40-foot (12 m) deep pit.
