International audience; During Severe Accidents (SAs) in Light Water Reactors (LWRs), the core heat up due to the lack of fuel cooling in the Reactor Pressure Vessel (RPV) may lead to the formation of a so called corium pool (molten core oxidic and m

During a severe accident in a nuclear reactor, core damage occurs and may lead to the formation of corium, followed by relocation to the vessel lower head. The decay heat released by the corium can threaten the integrity of the vessel, if no effectiv
