The nuclear fuel cycle
The nuclear fuel cycle consists of two phases: the front end and the back end.Front-end steps prepare uranium for use in nuclear reactors. Back-end steps ensure that used—or spent—but still highly radioactive, nuclear fuel is safely managed, prepared, and disposed of.. Nuclear power plants primarily use a specific type of uranium (U-235) for …
