Four recycling scenarios involving pyroprocessing of spent fuel (SF) have been investigatedfor a 600-MWe transmutation sodium-cooled fast reactor (SFR), KALIMER. Performanceevaluation was done with code system REBUS connected with TRANSX and TWODANT.
Scenario Number 1 is the pyroprocessing of Canada deuterium uranium (CANDU) SF.
Because the recycling of CANDU SF does not have any safety problems, the CANDU-Pyro-SFR system will be possible if the pyroprocessing capacity is large enough. ScenarioNumber 2 is a feasibility test of feed SF from a pressurized water reactor PWR. Thesensitivity of cooling time before prior to pyro-processing was studied. As the cooling timeincreases, excess reactivity at the beginning of the equilibrium cycle (BOEC) decreases,thereby creating advantageous reactivity control and improving the transmutation performanceof minor actinides. Scenario Number 3 is a case study for various levels of recoveryfactors of transuranic isotopes (TRUs). If long-lived fission products can beseparated during pyroprocessing, the waste that is not recovered is classified as low- andintermediate-level waste, and it is sufficient to be disposed of in an underground site due tovery low-heat-generation rate when the waste cooling time becomes >300 years at a TRUrecovery factor of 99.9%. Scenario Number 4 is a case study for the recovery factor of rareearth (RE) isotopes. The RE isotope recovery factor should be lowered to 20% in order tomake sodium void reactivity less than <7$, which is the design limit of a metal fuel
