Unreasonable interface settings between reactor and turbine for nuclear power plant may cause reactor trip. Through researching the reactor and turbine protection as well as the interface between them, it is proposed that optimizing and improving the limit value of fault pressure of condense may effectively solve the trip risk caused by "condenser fault" due to vacuum breaking valve automatically opens. In addition, maintaining the original design of condenser vacuum breaking valve may greatly guarantee the safety and reliable operation of turbine, and the availability of nuclear reactor is enhanced;thus safety and reliable operation of entire nuclear power plant is guaranteed technically.
