摘　　要：对3种核电站电缆用材料进行了辐照老化试验,得到了材料主要性能如断裂伸长率、抗张强度、硬度、体积电阻率等与辐照剂量以及剂量率的变化关系,并且还研究了不同辐照类型射线对材料老化的影响,为正确选择核电站用1E级电缆质量鉴定试验条件提供了依据。Three materials for class 1E cables for nuclear power plant were subjected to the irradiation ageing test, by which the relationship between the main material properties, such as tensile strength, elongation at break, hardness and volume resistivity, and irradiation dose and dose rate was established. Besides, the influence of different kinds of irradiations on the ageing of materials was investigated. These data provide the base for the qualification test requirements for proper selection of class 1 E category cables for nuclear power plant.
