新一代反应堆堆内构件材料

Discussion on RVI Material for the New Generation Nuclear Reactor

根据新一代反应堆堆内构件的环境条件,提出堆内构件选材原则,介绍了堆内材料相关发展动态以及5类材料的应用情况,然后对材料性能进行了综合分析,结果表明,镍基合金Inconel690、奥氏体不锈钢316LN、铁镍合金LF2和Incoloy 800有希望在新一代反应堆堆内构件中得到应用。

Based on the environmental condition in which the RVI for the new generation nuclear reactor works, the principle of material selection was proposed. Furthermore, the development irend of reactor material and five kinds of materials for it were described, and the properties of these materials were also analyzed. The results showed that nick- el-based Inconel alloy 690, austenitic stainless steel 316LN, Fe-Ni alloy LF2 and Incoloy 800 are expected to be used as RVI material for the new generation reactor.
