辐照监督试样用于监测核电站压力容器在工况环境下因辐照、热老化等因素引起的材料性能下降,是评估和保障反应堆安全运行的重要依据。其数量有限,不可复制替代。目前国内已抽取的辐照监督管试样中的断裂韧性试样,由于测试技术原因均处于保存状态。对于试验后的冲击及拉伸试样,由于其对于反应堆延寿及安全评估仍具有重要的参考价值,也应妥善保存。同时这些监督试样也是进行材
The radiation monitoring sample is used to monitor the material performance degradation caused by factors such as irradiation and heat aging in the pressure vessel of nuclear power plant in the working environment. It is an important basis for evaluating and ensuring the safe operation of the reactor. Its limited number, can not be copied instead. At present, the sample of the fracture toughness in the sample of the radiation supervisory tube that has been taken from China is kept in a preserved state due to the test technique. After the test impact and tensile specimens, because of its life extension and safety assessment of the reactor is still an important reference value, it should be properly preserved. At the same time these monitoring samples are also materials
