Uranium Country Notes
Between 1956 and 1988, the Power Reactor and Nuclear Fuel Development Corporation (PNC) and its predecessor undertook domestic exploration for uranium, resulting in the discovery of deposits at two locations on the island of Honshu. Total discovered reserves, reported as RAR recoverable at up to US$ 130/kgU, were some 6 600 tonnes at the beginning of 2005.
Cumulative production of uranium in Japan amounts to only 84 tonnes, produced by a test pilot plant operated by PNC at the Ningyo-toge mine between 1969 and 1982, together with a small-scale vat leaching test facility from 1978 to 1987.
