摘要： PURPOSE:To make possible the removal of decay heat generated in a reactor core by providing an emergency condenser housed in a cooling water source, primary piping connecting the emergency condenser to the gas phase part of a reactor pressure vessel and secondary piping coupling the emergency condenser to the reactor pressure vessel. CONSTITUTION:A nuclear power plant is provided with a reactor pressure vessel 21, a reactor containment vessel 22 and the like. The steam generated by the decay heat of a reactor core is led into an emergency condenser 32 through primary piping 31 from the reactor pressure vessel 21 to cool to condense in heat-transfer tubes to become condensed water to return to the reactor pressure vessel 21 through secondary piping 34, latent heat which the steam has is transmitted to the cooling water source on the outside of the reactor containment vessel 22 through the heat-transfer tubes of an emergency condenser 32, and non-condensable gas allowed to flow in the emergency condenser 32 leads part of the steam produced in the reactor core to the downstream side of the emergency condenser 32 so as to exhaust into a suppression chamber from tertiary piping 36.
