【Abstract】 This paper presents some observations which are related to life management of the reactor internals of the PWR, which include precaution measures, potential failure devices, failure mode, failure process and basic requirements on acceptance. Typical failure mode and dangerous region of the reactor in-ternals are determined and analyzed. Items requiring further study for the devices to be repaired or replaced are proposed.更多还原
