Quick Summary

Nuclear fuel is the material used to initiate and control nuclear fission on a large scale within a nuclear reactor. The primary steps of the nuclear fuel cycle involve uranium mining and extraction, enrichment, fuel fabrication, reactor irradiation, cooling, reprocessing, and waste disposal.12

The most common fuel for light-water reactors (LWRs) is uranium dioxide, processed into dense ceramic pellets and encased in zirconium alloy tubes. Uranium-235 (U-235) is the key fissile material, though it constitutes only about 0.72% of natural uranium, necessitating an enrichment process to increase its concentration for reactor fuel. Fertile materials, like uranium-238, can transform into fissile materials, extending the operational life of reactors. The controlled chain reaction in a reactor releases significant energy, forming the basis of nuclear power systems.13456
