Operation Plumbat is the name given to what's believed to have been an Israeli covert operation in 1968 to obtain yellowcake (processed uranium ore) to support the Israeli nuclear weapons effort. France stopped supplying Israel with uranium fuel for the Dimona nuclear reactor after the 1967 Arab-Israeli War. Numerous sources believe that in 1968 Israel managed to obtain 200 tonnes of yellowcake from the Belgian mining company Union Minière shipped out of Antwerp to Genoa for a European front company by transferring the ore to another vessel at sea. This Mossad covert operation violated Euratom controls of nuclear materials.
