摘要
相较于中子辐照,质子辐照实验具有成本低、周期短、辐照参数可精准控制以及辐照后样品没有放射性以便于后续开展性能测试、微观组织表征等优点,因此采用质子辐照实验的方式开展反应堆压力容器钢(reactor pressure vessel,RPV)辐照损伤效应的研究日益得到广泛应用。介绍了质子辐照实验的研究现状,对比了质子辐照与中子辐照的优缺点,讨论了质子辐照对材料微组织演变与力学及电磁性能的影响,分析了RPV钢质子辐照损伤机理,并评析了目前所取得的研究成果与存在的不足之处。最后提出了现阶段对国产RPV钢开展全面、系统的质子辐照实验研究工作的重要性与必要性。
Compared with neutron irradiation, proton irradiation experiment has the advantages of low cost, short period, precise control of irradiation parameters and no radioactivity of irradiated samples, which is convenient for facilitating subsequent performance testing and microstructures charactering.Therefore,effects of irradiation damage on the reactor pressure vessel steel have been studied widely by using the method of proton irradiation.In this paper,the research status of proton irradiation experiment was introduced, the advantages and disadvantages between proton irradiation and neutron irradiation were compared, how proton irradiation affects the microstructure development and mechanical, electro-magnetic properties of RPV steels were analyzed, the proton irradiation damage mechanism was discussed, and the current research achievements and shortcomings were also commented.Carrying out comprehensive and systematic research on the proton irradiation experiment is of great necessity and importance.
