The Nuclear Fuel Cycle refers to the series of processes involved in producing nuclear energy from uranium or other fissile materials. It begins with the mining and milling of uranium ore, which is then converted into a usable form, typically uranium dioxide. This fuel is enriched to increase the concentration of the fissile isotope, Uranium-235, before being fabricated into fuel rods for use in nuclear reactors. After the fuel is used in a reactor, it becomes spent fuel, which contains radioactive waste. The spent fuel can be reprocessed to recover usable materials, such as Plutonium and Uranium, or it can be stored in secure facilities. The final steps involve managing the waste, ensuring safety, and minimizing environmental impact throughout the cycle.
