摘要:

相較于中子輻照，質子輻照實驗具有成本低、周期短、輻照參數可精準控制以及輻照后樣品沒有放射性以便于后續開展性能測試、微觀組織表征等優點，因此采用質子輻照實驗的方式開展反應堆壓力容器鋼(reactor pressure vessel, RPV)輻照損傷效應的研究日益得到廣泛應用。介紹了質子輻照實驗的研究現狀，對比了質子輻照與中子輻照的優缺點，討論了質子輻照對材料微組織演變與力學及電磁性能的影響，分析了RPV鋼質子輻照損傷機理，并評析了目前所取得的研究成果與存在的不足之處。最后提出了現階段對國產RPV鋼開展全面、系統的質子輻照實驗研究工作的重要性與必要性。

Abstract:

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�瞞agnetic 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.
