What is in a nuclear reactor generator pump turbine or nuclear fuel?

A nuclear reactor generates heat through nuclear fission, primarily using nuclear fuel such as uranium or plutonium. This heat is used to produce steam, which drives a turbine connected to a generator, converting thermal energy into electrical energy. The reactor's coolant system, which can include pumps, circulates water or other coolants to transfer heat away from the reactor core, ensuring safe operation. Thus, while the turbine and generator convert energy, the nuclear fuel is essential for initiating and sustaining the fission process.
