浅谈反应堆压力容器主螺栓孔扩孔修复的核安全审查

Nuclear Safety Review of Enlarging Restoration on Main Flange Thread of Reactor Pressure Vessel

介绍了国内外处理严重损伤螺栓孔修复的技术概况,结合国内处理反应堆压力容器主螺栓孔不符合项的核安全审查,给出了核安全审查中应关注的方面以及力学评价存在的问题,以期望对后续的核安全审查有借鉴意义。

This paper introduces the technical current situation of restoration for severe damaged threads at are suggested and some existing problems of mechanical evaluation are identified, so as to be referred for subsequent nuclear safety review.
