在动力堆噪声探测中,传感器经长期运行和高辐照后,其动态特性是否保持稳定对正确地探测反应堆部件故障是非常重要的。如果发生变化,其规律如何和对测量结果有什么影响是值得研究的课题。图1中(a),(b)和(c)分别示出在高温高压回路上的钴自给能探测器在正常、异常 In the power reactor noise detection, the sensor after long-term operation and high radiation, the dynamic characteristics of the stability of the right to detect the reactor component failure is very important. If there is any change, the law and how it affects the measurement results are worth studying. Figure 1 (a), (b) and (c), respectively, shows the high temperature and pressure circuit in the self-powered cobalt detector in the normal, abnormal
