This work has been carried out within the framework of the EUROTRANS project - DM1 domain. The conceptual design of a lead cooled sub-critical reactor dedicated to the transmutation and incineration of Minor Actinides has been analysed, starting with a reactor model similar to the 80 MWth LBE PDS-XADS and tuning it to higher powers. The isotopic composition of the U-free combustible, MOX spent fuel after 30 years' cooling inserted in a MgO matrix (50% in volume), has been chosen in order to maintain the Keff sub-criticality level as more as possible constant during the cycle. In order to fast the Minor Actinides incineration, the care design has been regulated to achieve the max allowable power density. The reactor burning capability has been verified with the ERANOS deterministic code by means of seven years burn up calculations without refuelling.

Abstract
This work has been carried out within the framework of the EUROTRANS project - DM1 domain. The conceptual design of a lead cooled sub-critical reactor dedicated to the transmutation and incineration of Minor Actinides has been analysed, starting with a reactor model similar to the 80 MWth LBE PDS-XADS and tuning it to higher powers. The isotopic composition of the U-free combustible, MOX spent fuel after 30 years' cooling inserted in a MgO matrix (50% in volume), has been chosen in order to maintain the Keff sub-criticality level as more as possible constant during the cycle. In order to fast the Minor Actinides incineration, the care design has been regulated to achieve the max allowable power density. The reactor burning capability has been verified with the ERANOS deterministic code by means of seven years burn up calculations without refuelling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
