Articles on the technical foundations of nuclear safety: defence in depth, safety functions, protection and support systems, the management of design-basis and severe accidents, and decay heat removal. The focus is on physical processes, engineering solutions and verifiable evidence through which a plant prevents event progression, limits its consequences and reaches a safe state.
During a LOCA, the containment system receives mass and energy released from the damaged reactor coolant system. This article follows the initial pressure response, condensation, water collection, recirculation and long-term heat removal across different containment designs.
