Device for gas leak accident of a return Circuit of the nuclear power plant of pressurized water reactor

摘要

A device for the System Response to accidents of Nuclear Power Plant of pressurized water reactor, specifically a device in the Exhaust Gas System of accident of a First Circuit to the central nuclear pressurized water reactor includes Valve esca PE gas accident between the Tank reactor pressure and normal Valve exhaust gas.Exhaust Valve of gas accident are divided into two sets of two sets of normally closed Valves each.A First pair of normally closed electromagnetic Valves are connected in series to the series and a Second pair of electromagnetic Valves are normally closed the series B, which are connected in parallel to the gas Exhaust pipe of the safety valve Regulator V Oltaje and entering the Tank Pressure Relief.The advantage is that using the electromagnetic Valves to the system with stable and reliable performance and Rapid Action to effectively mitigate the consequences of accidents and ensure the integrity of the Reactor Pressure Vessel under severe accidents.
