Ageing Analysis and Assessment Methods for Reactor Pressure Vessel

The ageing mechanisms of PWR RPV include the irradiation embrittlement,thermal Ageing,temper embrittlement,fatigue,corrosion,and mechanical fretting/wear.Aging analysis of PWR RPV is a complicated process,which includes the understanding of aging mechanisms,aging related information,methods of aging data collection,methods of analysis and assessment.Based on recent researches on RPV aging analysis and assessment methods,the process and methods,are presented through tabular in this paper.This paper only concludes the aging susceptibility analysis methods,not involves time-limited aging analysis methods.
