Pressure boundary structure integrity verification method and device, equipment and storage medium

The invention discloses a pressure boundary structure integrity verification method, device and equipment and a storage medium, and relates to the technical field of nuclear power, the method comprises the following steps: obtaining leakage data of a reactor coolant system in a leakage test, the medium of the leakage test being fuel, and the pressure of the leakage test being standard operation pressure; acquiring a detection result of the reactor coolant system in a nondestructive testing test; and determining whether the pressure boundary structure of the reactor coolant system is complete or not according to the leakage data and the detection result. By adopting the technical scheme, the integrity verification workload and time cost can be reduced, meanwhile, the safety risk and the equipment fatigue damage risk brought to operators can be avoided, the service life of the reactor coolant system is prolonged, the maintenance cost is reduced, and the maintenance efficiency is improved. The effect of safely a
