摘　　要：为了完成高通量工程试验堆(HFETR)运行许可证延续(OLE)申请的安全论证,需要提供一份完整的时限老化分析(TLAA)清单,并通过计算或分析论证各项TLAA在延续运行期内是否满足安全运行的要求。基于美国压水堆核电厂TLAA的经验,采用“材料-环境-影响因素”分析法筛选出通用TLAA和潜在TLAA项目,同时识别出HFETR特定的TLAA项目,获得HFETR需要补充或重新计算分析的9项TLAA清单。通过每一项TLAA的评估结果表明,在10 a OLE内能够保证HFETR的安全性。In order to complete the safety demonstration of High Flux Engineering Test Reactor(HFETR) for the Operation License Extension(OLE) application,it is necessary to provide a complete list of time-limited aging analysis(TLAA),and demonstrate by calculation or analysis that each TLAA meets the requirements of safe operation in the extended operation period.Based on the TLAA experience of pressurized water nuclear power plants in the United States,this paper selects general TLAAs and potential TLAAs by means of “material-environment-influencing factors”,and identifies HFETR-specific TLAAs.Therefore,9 TLAAs need to be supplemented,recalculated or analyzed for HFETR.The results of each TLAA evaluation show that the security of HFETR can be guaranteed during 10-year license extension period.
