Transportation in shielded casks to the STAR facility. Reception of the casks and canister transfer to the processing cell. Identification and opening of the canister and identification of content. Mechanical removal of magnesium cladding. Separation of nuclear materials from Mg cladding waste and conditioning of this waste for specific disposal. Nuclear materials are then placed into a specially designed oven to go through following steps in order to withstand the effects of a hydrogen explosion.
SPENT FUEL STORAGE In FBTR fuel is discharged from the core and kept in an internal storage within the reactor vessel for cooling. It remains there until the decay heat reduces to less than 400 W.
These fuels come from either abandoned reactor types or laboratory experiments (fuel examinations, critical experiments, special fuel element designs) or the experimental reactors operated in Cadarache, Saclay and Grenoble. , the Cascad facility). Usually, the CEA chooses the reprocessing solution, because it is considered to be safer as far as waste is concerned. The fissile materials contained in these fuels follow a closed cycle: fabrication, irradiation, disassembly, reprocessing, re-fabrication and re-use).
