In the current context of nuclear revival under constraint global warming and an ever-increasing world demand for energy, it is essential to take all precautions in event a serious accident during design phase review severe mitigation features existing plants. The accompanied by development prototypes based on alternative concepts light water reactors, such as Sodium-cooled Fast Reactor (SFR), High Temperature (HTR), Molten Salt (MSR), which are also consideration reactors reduced power output, or Small Modular Reactors (SMR). This paper summarizes main outcomes achievements last five years experimental numerical research conducted at CEA/IRESNE into prospective accidents within Pressurized Water (PWR) SFRs.
