The NUMEC Affair: The Bomb-Grade Uranium That Vanished
The same investigation, restaged one beat at a time. Drive it with the arrow keys, space, or autoplay. Nothing is cut from the piece — long runs are split across frames. Read the full investigation or open the Israeli Influence on the United States hub.
The NUMEC affair.
Hundreds of kilos of weapons-grade uranium vanished from a small Pennsylvania plant — the largest such loss at any US commercial site. For 15 years, across four administrations, the CIA and FBI investigated whether it built Israel's bomb. The files are declassified now.
What gets dismissed today as an antisemitic 'conspiracy theory' was, for fifteen years, a formal US intelligence investigation. The record is FACT; the diversion itself is SOME SMOKE — a CIA case Carter's own staff called 'persuasive, though not conclusive,' never proven, and credibly disputed.
We reject the 'dual loyalty' trope and confine the claim to the declassified record: a specific quantity of uranium, a specific set of official investigations, one specific unresolved question. (We omit the viral 'Ben Shapiro's uncle' claim — unverified and chronologically impossible.)
Hundreds of kilos of bomb-grade uranium went unaccounted for — the largest such loss at any US commercial site.
A 1965 AEC inventory of HEU leased to NUMEC's Apollo, PA plant found a major shortfall; the AEC confirmed 178kg of U-235 missing in 1966, growing to 269kg. DOE records later show NUMEC had the largest HEU inventory loss of any US commercial site — 269kg before 1968, ~76kg after. NUMEC paid for it but disputed the math as processing loss.
A dozen US agencies across four administrations investigated whether it went to Israel — and never accounted for it.
1965–early 1980s: AEC/NRC, FBI, DOJ, CIA, the Joint Committee on Atomic Energy, GAO, NSC, DIA, and two House committees investigated. The FBI wiretapped Shapiro; DOJ declined to prosecute. In 2009 the NRC declined to clear him, saying it 'found no documents that provided specific evidence that diversion occurred' — while not clearing him. A declassified GAO study said a 'concerted effort' could have 'possibly solved the NUMEC diversion questions, if they desired to do so.'
The CIA believed it went to Israel — a case Carter's own staff called 'persuasive, though not conclusive.'
Feb 1976: the CIA briefed the NRC that it believed the missing HEU went to Israel; Carter was briefed, and his NSA staff concluded 'The CIA case is persuasive, though not conclusive.' A 1968 CIA finding reportedly traced US-origin HEU to the environs of Israel's Dimona reactor — recorded in former AEC chairman Glenn Seaborg's 1978 diary and supported by 2015-declassified CIA documents. Israeli operative Rafi Eitan (later Pollard's handler) visited the Apollo plant.
CIA vs. FBI: the agency pushed, and the case was quietly closed.
A March 11, 1976 CIA memo (Carl Duckett, DDS&T, to the DCI) lays it out. April 2, 1968: Helms wrote AG Ramsey Clark urging the FBI to investigate Shapiro's 'relationship with the Government of Israel' (ISCAP 2014); the AG ordered it. But by Sept 1969, Hoover reported the AEC had asked Shapiro only about passing 'classified information' — and 'Apparently no mention was made of the passage of nuclear material to a foreign government.' On a case about missing bomb-grade uranium and Israel, the Bureau never asked the central question, then discontinued the active probe. Helms pushed again (Oct 1969, urging surveillance as Shapiro 'planned to emigrate to Israel'); the memo: 'This was not done… There was no further FBI reporting on the case after that.' CIA Tel Aviv chief John Hadden: 'an Israeli operation from the beginning.' Reopened 1976 as 'DIVERT,' closed Jan 1981.
Whether it was actually diverted — never proven, and seriously disputed.
Suspicion side: the persuasive CIA case, the Dimona trace, Eitan's visit, a 2009 FBI ex-employee statement about HEU canisters loaded for a Zim-Israel ship. Exculpatory side: Hersh ('The Samson Option') concluded the material 'ended up in the air and water of Apollo… ducts, tubes, and floors'; the NRC attributed big later losses to contamination/scrubbers; Carl Duckett: 'I know of nothing at all to indicate that Shapiro was guilty'; Seaborg called the charges 'unjust.' Real missing uranium, 15 years of official suspicion — never established. Textbook SOME SMOKE.
Either it walked out the door, or it was lost into the walls. Both are the story.
If diverted, the US watched weapons-grade uranium reach a foreign bomb program and buried it. If lost, the government still couldn't account for enough bomb-grade material for several warheads, at the largest-loss site in the country. Both readings indict security, oversight, or candor. And the deeper point: the question of whether America helped or failed to stop Israel's bomb gets waved away as 'conspiracy' — when the CIA, FBI, AEC, and four administrations treated it as a live counterintelligence problem for fifteen years. It sits with JFK vs. Dimona and the Palestine Laboratory: the unromantic, documented history, with the black bars coming off.
