摘要
堆内构件是反应堆内部的关键设备,属安全相关级。由于长期工作在高温、高压和高辐照的环境条件,对堆内构件材料的要求较高。结合不同国家堆内构件常用牌号的几种不锈钢材料,分析了它们的耐腐蚀性能、焊接性以及辐照性能等,从而给出了推荐的材料选择。
As a key equipment, reactor vessel internals （RVI） influence the safeW of nuclear power plant. There is a rigid requirement for the structural material of reactor vessel inter- nals because of the high temperatmre, high pressure and high dose irradiation. Combining the stainless steel usually used in different nations, the paper analyzes the corrosion resistance prop- erty, weldability and irradiation property and recommends the optimum stock option.
