Reactor containment

WebThe containment building is a gas-tight (shell) or other enclosure around a nuclear reactor and a primary circuit. The Containment is the most characteristic structure of a nuclear power plant. Practically all nuclear power plants built during the last few decades include a containment building. WebThe containment structure consists of a reactor containment vessel, service area, and an emergency air purification system, which reduce the release of FPs to the environment during the postulated accidents. The containment vessel is designed to withstand the temperature and pressure transients and to be leak-tight within the specified limits ...
