Evidence that missing uranium went to Israel withheld since 1968
According to formerly top-secret and secret Central Intelligence Agency files (PDF) released August 31 in response to a Freedom of Information Act lawsuit (PDF), the agency’s long retention of key information ultimately stymied two FBI investigations into the 1960s diversion of weapons-grade uranium from a Pennsylvania-based government contractor into the Israeli nuclear weapons program.
The Nuclear Materials and Equipment Corporation (NUMEC) was a nuclear fuel processing company founded by legendary chemist Zalman Mordecai Shapiro and financed by entrepreneur David Luzer Lowenthal. According to the Department of Energy, during Shapiro’s reign at NUMEC, the company lost more weapons-grade uranium – 337 kilograms after accounting for losses – much of a particularly unique and high enrichment level than any other U.S. facility. Losses only returned to industry norms after Shapiro, who later unsuccessfully tried to get a job working on advanced hydrogen bomb designs, was forced out of NUMEC.
