As noted in previous posts. the Y-12 nuclear weapons plant mistakenly sent too much uranium (highly enriched, more than 93 percent U-235) to Mirion Technologies, a NRC-licensed facility in Horseheads, N.Y., in July. In fact, the kilogram of uranium metal was 10 times what was supposed to be sent, raising all sorts of issues and violating Department of Transportation regulations. As soon as Mirion discovered the error, a team from Y-12 went to New York to make sure the overload of fissile material was safely packaged and returned to Oak Ridge.
Among the questions that hadn’t been answered was whether Mirion Technologies ever received its correct order, which was reportedly 100 grams of HEU.
Steven Wyatt, a spokesman for the National Nuclear Security Administration’s Production Office, which oversees Y-12 operations, confirmed that Mirion did eventually get the correct amount of material, although he didn’t provide the date it was delivered.
Seth Rosen, executive vice president and general counsel for Mirion Technologies, described the company as a “leading global provider of radiation safety systems and services.”
As for the use of the material acquired from Y-12, Rosen said, “We incorporate uranium in small amounts into our neutron sensors used in commercial nuclear power plants.”
