In order to multiply by three or four the combustion level of nuclear fuel pellets in fast neutron nuclear reactors, it is proposed that following a normal irradiation period of said pellets in the reactor core, that the irradiated can be replaced by a new can with an internal diameter slightly exceeding that of the first can. Thus, the pellets can undergo a new irradiation cycle in the reactor core. Preferably, the can is destroyed by progressive local melting over its entire length and the new can is preheated to facilitate the introduction of the pell...
A process for the recycling of nuclear fuel pellets contained in a first metal can in which these pellets and said first metal can have previously been irradiated in a fast neutron nuclear reactor, wherein the process comprises extracting the pellets from the first irradiated can and introducing these pellets into a second unirradiated metal can before irradiating again said pellets contained in said unirradiated second metal can in a fast neutron reactor, said unirradiated metal can having a larger internal diameter than the internal diameter of the fir...
