Abstract

Abstract

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.
