The 26-megawatt Dimona reactor is where Israel gets its supplies of tritium, said Robert Kelley, a U.S. nuclear-weapons engineer who directed IAEA inspections in Iraq both in 1992 and 2001. The radioactive isotope is needed to detonate the armaments believed to be in Israel’s stockpile. Without fresh sources of tritium, “the weapons become a military dud,” Kelley wrote in a report commissioned by Jane’s IHS. He also said Israel’s refusal to sign the Nuclear Non-Proliferation Treaty will complicate efforts to replace the reactor.
