External Reactor Vessel Cooling Evaluation for Severe Accident Mitigation in NPP Krško
Journal of Energy : Energija, 2022 The In-Vessel corium Retention (IVR) through the External Reactor Vessel Cooling (ERVC) is mean for maintaining the reactor vessel integrity during a severe accident, by cooling and retaining the molten material inside the reactor vessel. By doing this, significant portion of severe accident negative phenomena connected with reactor vessel failure ...
