U.S. National Nuclear Security Administration announced that is completed the transfer of about 700 kg of HEU from the United Kingdom. The transfer was a result of a swap agreement reached in 2016. The United States would down-blend the UK material and used it in nuclear reactor fuel. The agreement also committed the United States to providing HEU for European research reactors, including those involved in production of medical isotopes. As it was noted at the time, the agreement, while removing some HEU from the United Kingdom legitimized the continuing practice of supplying HEU to Europe. The last transfer of this kind was approved in October 2018.
