摘要
Abstract
Reactor pressure vessel (RPV) is the place where nuclear fuel is loaded and fissioning,and its running condition is demanding,need to bearing strong radiation,high temperature and pressure,and to have at last has 40 years′ service life,so it requires high quality.In addition to normal use,it is necessary to minimize the degradation damage caused by human factors to RPV.For the many bumped defects found by visual inspection to the reactor pressure vessel inner surface after hot test in one nuclear power unit,this paper analyzed its causes and discussed the precaution and treatment method to the defects,and had some guidance significance to the follow-up reactor pressure vessel maintenance.关键词
