WebOct 2, 2024 · Abstract. Reactor pressure vessel (RPV) of a pressurized water reactor (PWR) is an important pressure retaining equipment which decides the life of a nuclear power plant. RPV is constructed of special quality nuclear grade low-alloy steel having sufficient fracture toughness at the beginning of life and a good resistance to neutron embrittlement. Webhavior of the RPV wall, the creep law (Mao et al., 2016d) with a number of free parameters is formulated as follows, "Pc Dd1˙d2"d3 c exp d4 T ; (1) Wherein, the d1, d2, d3, d4 are material coefﬁcients by ﬁtting the creep law to test data obtained at constant load and tem-perature. As for the RPV steel, its creep process experiences
