摘要
介绍了近年来在假想堆芯熔化严重事故下国内外反应堆压力容器材料高温蠕变行为的研究进展及现状,着重阐述了在材料高温蠕变试验、缩比模型试验和数值模拟等方面取得的成果,并提出了目前存在的问题及未来的发展方向。
An overview of research status and progress on high-temperature creep behavior pressure vessel considering the hypothetical core melt down scenario is presented in this paper. is placed on accomplished achievements in The present problems as well as the future of reactor Emphasis creep tests, scale model experiments and numerical simulation. development are also suggested.
