WASHINGTON, Aug 18 (Reuters) - The Biden administration has tightened controls on the export of materials and components for nuclear power plants to China, saying it would ensure the items were used only for peaceful purposes and not the proliferation of atomic weapons. The Nuclear Regulatory Commission (NRC), the federal agency responsible for nuclear energy safety, also requires exporters to get specific licenses to export special nuclear material and source material. That includes different types of uranium as well as deuterium, a hydrogen isotope that, in large amounts, could be used in reactors to make tritium, a nuclear weapons component. China opposes "putting geopolitical interests above nuclear non-proliferation efforts," he said. Two exports to China of the regulated nuclear materials occurred under a general license in the last year.
