Visited Numec as part of Israeli intelligence who's-who, described as Israeli defence ministry chemist but actually top Mossad operative who later headed Lakam; linked to suspected uranium theft

Investigation into alarming missing fissile material at Numec shelved with no charges due to potential consequences for US-Israel relations

LAKAM cultivated a source at the Nuclear Materials and Equipment Corporation (NUMEC) in Apollo, Pennsylvania, resulting in the diversion of 91 kilograms of highly enriched uranium in 1965, which fueled Israel's nuclear weapons program. The diversion was investigated by the Atomic Energy Commission (AEC), FBI, CIA, and multiple congressional committees from 1965 onward. The AEC discovered the missing uranium in 1965, and the FBI briefed President Nixon on NUMEC's activities in 1969. A 1974 CIA report concluded Israel developed nuclear weapons using material obtained through 'clandestine means.' The Nuclear Regulatory Commission's 1983 report NUREG-0627 concluded that significant quantities of HEU could have been removed by a knowledgeable insider with LAKAM connections.

CIA suspected some fissile fuel in Israel's bombs was weapons-grade uranium stolen from Numec; Rafael Eitan and other Israeli intelligence visited site
