From Canada with love: Repatriating HEU to the U.S.
As part of a nonproliferation agreement, Canada and the U.S. undertook a multi-year campaign to ship liquid high-enriched uranium material from Chalk River to Savannah River.
In March 2012, during the Nuclear Security Summit in Seoul, South Korea, the governments of Canada and the United States committed to work cooperatively to repatriate approximately 6,000 gallons of high-enriched uranyl nitrate liquid (HEUNL) target residue material (TRM) stored at the Chalk River Laboratories in Ontario to the U.S. Department of Energy’s Savannah River Site in South Carolina. The announcement was part of a larger agreement between the two countries to reduce proliferation risks by consolidating high-enriched uranium at a smaller number of secure locations.
