The fuel that is used in a nuclear reactor is called uranium 325 the uranium is used in little pellets, less than an inch long, that generate about the same energy as a ton of coal these pellets are placed into rods made of zirconium, which prevent products of the fission from being emmitted to the outside world. An easy-to-understand introduction to what happens inside a nuclear power plant nasa's scientific nuclear reactor at plum a nuclear power plant works. Power plant operators, distributors, and dispatchers typically need a high school diploma or equivalent combined with extensive on-the-job training, which may include a combination of classroom and hands-on training many jobs require a background check and screenings for drugs and alcohol nuclear power reactor operators also need a. This is called a “chain reaction” controlling that chain reaction is what nuclear reactors do the nuclear process turning that chain reaction into electricity takes several steps operators load uranium fuel into a reactor core neutrons strike it, starting the chain reaction, which can continue as long as fissionable fuel remains in the core.
