| 摘要: |
| 轻水反应堆分为压水反应堆及沸水反应堆两种,我国使用的主要为压水堆,而国内部分反应堆已逐渐进入服役中后期。反应堆中的材料与燃料经受着3项严酷的考验:高温、腐蚀环境和裂变过程中释放的高能粒子的破坏,使材料的性能退化、甚至失效。为使材料能够安全运行并具有与其他能源的竞争性,核反应堆的延寿或新建时避免出现目前已经遇到的缺陷,应尽早对现有材料的服役性能和改进措施进行研究和讨论。 |

| Abstract: |
| Light water reactors are divided into two types, i.e., the pressurized water reactor and the boiling water reactor. Pressurized water reactors are mainly used in China, while some domestic reactors have gradually entered the middle and late stages of service. The materials and fuels applied in the reactors are subjected to three severe tests: high temperature, corrosive environment, and destruction of high-energy particles released during fission, which degrade the performance of the material and even cause the material to fail. To ensure the operation safety of the material and its competitiveness with other energy sources, for the life extension or new construction of nuclear reactors, it is urgent to study and analyze the service performance and improvement measures of the existing materials so as to avoid the defects that have been encountered. |
