摘要
本文对JRC EC管理的“核知识保存与巩固,WWER - WS2”项目框架内的92篇论文进行了综述,其中大部分论文选自ODIN数据库。本文包含了WWER RPV材料辐射后退火和再辐照的实验结果。这些论文发表的结果已在RRC KI, VTT, NRI Rez, Forschungszentrum Dresden-Rossendorf,由RRC KI, VTT- fortum, JRC EC和ITEP, RRC KI和ORNL以及IAEA国际项目的国际合作中获得。本文主要研究了以下几个问题:辐照下RPV材料性能和结构的演变;辐照RPV材料在退火条件下性能和结构的恢复;化学成分对辐照RPV材料回收转变温度的影响退火对WWER RPV材料力学性能恢复的影响辐射后退火引起的组织演化;辐照后退火对辐照后WWER-1000 RPV材料力学性能的影响re-irradiation行为;退火后操作的监督程序;RPV状态评估;有关退火的技术问题;以及退火的许可问题。
Post-irradiation annealing and re-irradiation review
This paper summarises the review of 92 papers most of them selected from the ODIN database made within the framework of the project ‘Nuclear Knowledge Preservation & Consolidation, WWER – WS2’ managed by JRC EC. The papers contain the experimental results concerning postirradiation annealing and re-irradiation of WWER RPV materials. The results published in these papers have been obtained in RRC KI, VTT, NRI Rez, Forschungszentrum Dresden-Rossendorf, with the international cooperation between RRC KI, VTT-Fortum, JRC EC and ITEP, RRC KI and ORNL, and IAEA International Project. The following problems are examined in the review: evolution of RPV materials properties and structure under irradiation; recovery of irradiated RPV materials properties and structure under annealing; chemical composition effect on transition temperature of irradiated RPV materials recovery; effect of fluence on WWER RPV materials mechanical properties recovery due to annealing; microstructure evolution due to postirradiation annealing; effect of post-irradiation annealing on mechanical properties of irradiated WWER-1000 RPV materials; re-irradiation behaviour; surveillance programme for the post-annealing operation; assessment of the RPV state; technical problems concerning annealing; and licensing problems for annealing.
