摘要
反应堆压力容器(RPV)材料经受中子辐照后,发生脆化效应导致韧性降低是影响反应堆安全运行的重大因素。为准确评估国产RPV的安全性,采用国产RPV材料在试验堆内加速模拟辐照的试验方法,研究国产RPV材料的辐照脆化性能。结果表明,国产RPV材料在寿期运行工况下,存在一定程度的辐照强化效应和辐照脆化效应。
Reactor safety is mainly influenced by irradiation embrittlement and fracture toughness decreasing of reactor pressure vessel(RPV) steel. To evaluate RPV safety,it is important to research irradiation effect of RPV steels under high neutron fluence. Programs about the embrittlement research of Chinese domestic RPV materials by the irradiation tests are described in this paper. The results indicated that there is irradiation embrittlement and fracture toughness decreasing in high neutron exposure for Chinese domestic RPV materials under the operation condition.
