Nuclear Fuel Cycle

Fissile material represents one of the fuels which are presently used for electricity production, but with respect to fossil fuels (coal, oil, gas), nuclear fuel presents two major differences: it must undergo several transformations, starting from the raw material, so that it can be introduced in nuclear reactor cores in the form of fissile subassemblies,after in-core iiradiation, during which part of the fissile material has been burnt, the remaining fissile element (235U), or the one which has been produced by irradiation process (239Pu), can be eventually recovered and reused in nuclear plants.
