A Starting Procedure for the MSFR: Approach to Criticality and Incident Analysis

Abstract : Molten salt reactors are liquid-fueled reactors so that they are flexible in terms of operation (load-following capabilities…) or design (core geometry, fuel composition, specific power level…) choices, but they are very different in terms of design and safety approach compared to solidfueled reactors. Such reactors call for a new definition of their operating procedures. Dedicated studies are performed in the frame of the European SAMOFAR (Safety Assessment of Molten Salt Fast Reactors) project of Horizon2020. This paper focuses on the behavior of the MSFR fuel circuit in interaction with the intermediate circuit. It is devoted to the start-up procedure of the MSFR, including the description of the proposed procedure, a presentation of the approach to criticality and the reactivity measurement during the filling of the core, and finally studies of accident scenarios (overcooling, reactivity insertion) at low power during the divergence step of the MSFR, highlighting the very good behavior of the reactor to such abnormal transients.
