摘要:

相較于中子輻照，質(zhì)子輻照實(shí)驗(yàn)具有成本低、周期短、輻照參數(shù)可精準(zhǔn)控制以及輻照后樣品沒有放射性以便于后續(xù)開展性能測(cè)試、微觀組織表征等優(yōu)點(diǎn)，因此采用質(zhì)子輻照實(shí)驗(yàn)的方式開展反應(yīng)堆壓力容器鋼(reactor pressure vessel, RPV)輻照損傷效應(yīng)的研究日益得到廣泛應(yīng)用。介紹了質(zhì)子輻照實(shí)驗(yàn)的研究現(xiàn)狀，對(duì)比了質(zhì)子輻照與中子輻照的優(yōu)缺點(diǎn)，討論了質(zhì)子輻照對(duì)材料微組織演變與力學(xué)及電磁性能的影響，分析了RPV鋼質(zhì)子輻照損傷機(jī)理，并評(píng)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(xiàn)階段對(duì)國(guó)產(chǎn)RPV鋼開展全面、系統(tǒng)的質(zhì)子輻照實(shí)驗(yàn)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.
