The Molten Salt Fast Reactor MSFR with its liquid circulating fuel and its fast neutron spectrum calls for a new safety approach and adaptation of the analysis tools. In the frame of the Horizon2020 program SAMOFAR Safety Assessment of the Molten Salt Fast Reactor a safety approach suitable for Molten Salt Reactors has been developed and is now applied to the MSFR. For this purpose the Lines of Defence LoD method is selected to drive the design consistently with the Defence in Depth principle. This paper presents the main characteristics of the method along with some practical guidelines to apply it to the specific case of the MSFR moreover some initiating events are analyzed through the implementation of the LoD tool. The outcomes of this analysis drive the design evolution. 1 Introduction MLD a list of accidents initiators has been identified for the plant state corresponding to the nominal conditions Nuclear power is recognized as an outstanding source for during power production 4 5 6 7 . In parallel a list of base load low-carbon electricity production and it is design key-points that are .
