The key equipment of high-temperature gas-cooled reactors is always exposed to nuclear irradiation, while the influence of nuclear irradiation on equipment fatigue life is one of the targets to be studied. Based on the expansion mechanism of fatigue cracks of fracture mechanics, combined with actual material parameters, the critical parts of the equipment, the position and time of occurrence of the working tolerance limit are pre-critically analyzed, and the fatigue life model under the influence of nuclear irradiation are corrected to calculate the influence of nuclear radiation on fatigue life which has certain guiding significance for the estimation of fatigue life of key equipment in high temperature gas cooled reactor.
