In　2016,　The　first　nuclear　power　plant　submitted　an　application　for　renewal　of　operation　license　to　National　Nuclear　Safety　Administration　(NNSA)　in　China.　In　order　to　guide　the　project,　NNSA　issued　the　technical　policy　for　extension　of　the　validity　period　of　the　nuclear　power　plant　operation　license,　which　mainly　refers　to　the　US　nuclear　power　plant　license　renewal　review　policy.　However,　China＇s　nuclear　safety　regulation　system　mainly　refers　to　the　establishment　of　the　International　Atomic　Energy　Agency　(IAEA),　and　carries　out　10-year　Periodic　Safety　Review　for　nuclear　power　plants　in　the　actual　operation　process.　There　are　some　differences　between　the　U.S.　license　renewal　strategy　and　the　IAEA　longterm　operation　system.　An　important　part　of　both　is　aging　management.　Based　on　the　daily　operation　and　supervision　of　China＇s　nuclear　power　plants,　this　paper　summarizes　the　differences　and　similarities　of　aging　management　between　periodic　safety　review　and　operation　license　renewal　application,　and　puts　forward　the　contents　that　should　be　added　and　improved　in　the　periodic　safety　review,　so　as　to　effectively　link　up　the　application　system　for　operation　license　renewal　and　the　Periodic　Safety　Review　system,　to　revise　the　＇Periodic　safety　review　of　nuclear　power　plant＇(　HAD103/11)　and　＇Aging　management　of　nuclear　power　plant＇(HAD　103/12)　provide　reference.　©　2021　American　Society　of　Mechanical　Engineers　(ASME).　All　rights　reserved.
