    Abstract

    In contrast to solid fueled reactors, simulations of a Molten Salt Reactor (MSR) core require tight coupling of neutronics and thermohydraulics due to the circulation of delayed neutron precursors (DNP) and fission products and to the thermohydraulic feedback on the temperature and density of the reactor core. The SEALION project aims at developing regulatory compliant multiphysics software for this coupling, intended for licensing of molten salt reactors. Central to the SEALION project is the application of an external coupling scheme, relying on singlephysics, neutronics and thermohydraulics software tools, applying the Transient Fission Matrix (TFM) approach for pre-calculating the spatial and temporal neutronics response. The overall structure of the SEALION software suite is presented and the TFM method based on MCNP is applied on a simplified molten salt reactor geometry, showing the feasibility of the approach.
