| Popis: | International audience; In-Vessel melt Retention (IVR) is a Severe Accident (SA) mitigation measure applied in some Pressurized Water Reactors (PWRs) in order to cool down molten fuel (corium) inside the Reactor Pressure Vessel (RPV) by flooding the reactor cavity and cooling the RPV external surface with water. The safety demonstration provided to a national safety authority to support a reactor concept crediting the IVR strategy to enhance safety of an existing plant or to license a new generation design can be based on both deterministic and Probabilistic Risk Assessment (PRA). Experimental data can be used to support analyses or to validate models implemented in computer codes. This paper provides Technical Safety Organisations (TSOs) perspectives to review IVR as SA mitigation measure applied in NPP. The paper is structured as it is advised in the European Technical Safety Organisations Network (ETSON) Technical Safety Assessment Guide ETSON/2013-003. |
