Résumé

This paper presents decay heat calculations and an application of the lines of defence method on 300 MWth chloride molten salt reactor ARAMIS-A. Decay heat calculations were performed with the CEREIS code, an under-development CNRS Python code, coupled with SERPENT2, which ensures reactivity control by fuel salt batch feeding. Results were compared to the benchmarked CNRS REM code and lead to a maximum total decay heat of 21.32 MW (7.1% of nominal power). The lines of defence method was applied to identify needed fuel salt locations and decay heat removal systems reliability requirements to ensure the decay heat removal safety function. This analysis leads to a proposition of 4 locations, with dedicated decay heat removal systems, and 3 containment barriers.
