摘要：PURPOSE:To provide a pressure relieving device of a nuclear reactor
containment vessel, by which switching control of control valves of a dry well vent line as well as a wet well vent line is automatically carried out according to the pressure in the nuclear reactor containment vessel, by which the pressure in the nuclear reactor
containment is maintained at an appropriate level, by which the burden on an operator is reduced while the soundness of the nuclear reactor containment vessel is maintained,and by which the quantity of radioactive material is reduced. CONSTITUTION:A pressure
relieving system into which control valves 14, 15 for reducing the pressure in a nuclear reactor containment vessel 3, in which a nuclear reactor pressure vessel 2 is housed, and which is provided with a pressure suppress chamber 5, and pressure detectors 16, 17 provided in the nuclear reactor containment vessel 3 are provided in the nuclear reactor containment vessel 3. A controller 19 is provided, which issues a control command for appropriately maintaining the pressure in the nuclear reactor containment vessel 3, by opening the control valves 14, 15 of the pressure relieving system when the pressure in the nuclear reactor containment vessel 3 exceeds a set value as a result of inputt
ing the signals of the pressure detectors 16, 17, and by closing the control valves 14, 15 when the pressure is reduced below the set level.
