nuclear materials
Reactor fuel stockpiles
Nuclear materials are substances capable of sustaining nuclear fission or fusion reactions, or that are radioactive byproducts of such reactions.
The term covers uranium, plutonium, and other fissile elements used in reactors and weapons, as well as spent fuel and radioactive waste.
International treaties strictly regulate the transport, storage, and accounting of nuclear materials: The inspectors verified all nuclear materials were present.
