Draft:BEPO (reactor)

From Wikipedia, the free encyclopedia

BEPO, which stands for British Experimental Pile 0, was an experimental nuclear reactor in Harwell, Oxfordshire, England, operated by the Atomic Energy Research Establishment. It was a 6-megawatt thermal (MWth) air-cooled, graphite-moderated reactor based on the prior GLEEP reactor. Construction began in June 1946, and it achieved criticality on July 3, 1948, operating until 1968.

The reactor core consisted of 28,000 graphite blocks weighing about 700 tonnes, arranged in a cube with horizontal channels for its uranium fuel slugs, control rods, and experimental access. The assembly was encased inside a 6-foot (1.8-meter) thick biological shield made of high-density concrete, with 6-inch-thick steel thermal shield plates lining the inside. The reactor utilized 40 tonnes of natural uranium fuel clad in aluminum.

While BEPO was initially intended for plutonium production, it was later turned into a dedicated research reactor that produced radioactive isotopes for medical purposes. It served as a pivotal resource for studying the core and cooling system performance that directly informed the design of the first-generation Magnox and subsequent Advanced Gas-cooled Reactors (AGR).
