摘　　要：反应堆压力容器(RPV)的辐照脆化问题是核安全的重中之重,影响到核电厂的安全性、经济性与公众信心。介绍了传统RPV辐照监督方案,讨论了现行技术的局限性,梳理了RPV辐照监督无损评估技术国外研究进展与存在问题,在实验与理论研究的基础上创新性地提出了中子辐照条件下RPV钢力学性能预测统一模型,并形成了基于电磁性能的RPV辐照监督无损评估技术,进一步完善后具有较好的工程应用前景。同时指出了开展RPV钢电磁性能实验研究,既有助于从一个全新的角度理解与再认识国产RPV钢长寿期服役时的辐照脆化行为,又有利于揭示RPV钢辐照脆化机理,丰富辐照脆化的基础理论。Neutron irradiation embrittlement of reactor pressure vessel(RPV) is the most important issue in nuclear safety, which affects the safety and economy of and public confidence in nuclear power plants. This paper introduces the traditional RPV irradiation surveillance method, discusses its limitations, combs the research progress and existing problems of RPV irradiation embrittlement non-destructive evaluation(NDE) technology, creatively puts forward a unified model for predicting the mechanical properties of RPV steel under neutron irradiation based on experiment and theoretical research, and forms a new NDE technology based on electromagnetic properties, which has a good engineering application prospects after further improvement. At the same time, this paper points out that the experimental study of electro-magnetic properties of RPV steel will not only help us to understand and recognize the irradiation embrittlement behavior of RPV steel in long service life, but also help to reveal the mechanism and enrich the basic theory of irradiation embrittlement.
