Did Israel steal uranium from the U.S. to build its first nuclear weapons?

Scott C. Johnson writes: Beginning in the early 1960s, investigators from the Atomic Energy Commission (AEC), the agency that regulated U.S. nuclear facilities at the time, began to question how large amounts of highly enriched, weapons-grade uranium had gone missing from NUMEC [the Nuclear Materials and Equipment Corporation in Apollo, Pennsylvania]. Any nuclear site had a certain amount of loss, from seepage into walls and floors, for instance. In fact, between 1952 and 1968, lax standards at 20 of the country’s commercial nuclear sites resulted in an apparent loss of 995 kilograms (2,194 pounds) of uranium-235. But investigators found that at NUMEC, hundreds of pounds went missing, more than at any other plant.

NUMEC’s founder, Zalman Shapiro, an accomplished American chemist, addressed the concern in 1978, telling Arizona Congressman Morris Udall that the uranium simply escaped through the facility’s air ducts, cement, and wastewater. Others, such as the late Glenn Seaborg, the AEC’s chairman in the 1960s — who had previously helped discover plutonium and made key contributions to the Manhattan Project — have suggested that the sloppy accounting and government regulations of the mid-20th century meant that keeping track of losses in America’s newborn nuclear industry was well near impossible. Today, some people in Apollo think that at least a portion of the uranium might be buried in Parks [Township], contaminating the earth and, ultimately, human beings.

But a number of nuclear experts and intelligence officials propose another theory straight out of an espionage thriller: that the uranium was diverted — stolen by spies working for the Mossad, Israel’s intelligence agency. In the 1960s, to secure nuclear technology and materials, Israel mounted covert operations around the world, including at least one alleged open-ocean transfer of hundreds of pounds of uranium. Some experts have also raised questions about Shapiro himself. He had contacts deep within Israel’s defense and intelligence establishments when he ran NUMEC; several of them even turned up at his facility over time and concealed their professional identities while there.

Fifty years after investigations began — they have involved, at various times, the AEC and its successors, Congress, the FBI, the CIA, and other government agencies — NUMEC remains one of the most confounding puzzles of the nuclear era. [Continue reading…]
