摘　　要：以关注轻水反应堆压力容器(LWR-RPV)寿命为焦点,着重探讨了NRC-RG1.99-2中辐照脆化预计公式应用的局限性和不保守性;并建议对目前新建造的LWR-RPV的辐照脆化预计由新的公式取代或修改NRC-RG1.99-2中的公式。This paper focuses on the LWR-RPV lifetime and discusses the application limitation and non-conservative for the irradiation embrittlement predictive formula in NRC-RG1.99-2. It is suggested that a new irradiation embrittlement predictive formula shall be used for the newly built LWR-RPV, or the formula in NRC-RG1.99-2 shall be revised.

关 键 词：RPV寿命 辐照脆化 RG1.99-2
