The U.S. Department of Energy said on June 4, 2014 it will study the environmental risk of importing spent nuclear fuel from Germany that contains highly enriched uranium, a move believed to be the first for the United States. The department said it is considering a plan to ship the nuclear waste from Germany to the Savannah River Site, a federal facility in South Carolina. The 310-acre site already holds millions of gallons of high-level nuclear waste in tanks. The waste came from reactors in South Carolina that produced plutonium for nuclear weapons from 1953 to 1989.
The Energy Department said it wants to remove 900 kilograms (1,984 pounds) of uranium the United States sold to Germany years ago and render it safe under U.S. nuclear non-proliferation treaties. A technique for the three-year process of extracting the uranium, which is contained in graphite balls, is being developed at the site in South Carolina, according to the Energy Department.
[The radioactive waste to be imported to the United States from Germany consists of 152 30-tonne CASTOR casks containing 290,000 graphite balls from the AVR gas-cooled prototype reactor, stored at the Juelich research center [Forschungszentrum Jülich (FZJ)], and 305 CASTOR casks containing 605,000 graphite balls from the THTR-300 reactor, stored at the Ahaus waste site. While the waste contains some US-origin highly enriched uranium (HEU), the amount is unclear as the material was irradiated and has been in storage for over 20 years since the reactors closed.]
Some critics question whether the department has fully developed a clear plan to dispose of the radioactive waste.”They’re proposing to extract the uranium and reuse it as fuel by a process that has never been done before,” said Tom Clements, president of SRS Watch, a nuclear watchdog group in South Carolina….
Sources told Reuters in May that German utilities were in talks with the government about setting up a “bad bank” for nuclear plants, in response to German Chancellor Angela Merkel’s decision to close them all by 2022 after Japan’s Fukushima nuclear disaster.
