安全壳泄漏率测量仪表体积权重分配方法研究

Research on Weight of Volume for Leakage Measurement Probe during CTT

安全壳整体泄漏率是安全壳打压试验中一个重要的验收指标,安全壳内温度、湿度探头所代表的体积分布方案及体积权重的准确度对安全壳的整体泄漏率测量结果有直接影响。通过对安全壳打压试验期间安全壳内气体温度和湿度分布进行分析,利用最优路径思想,提出一种安全壳打压试验泄漏率测量仪表的体积权重分配计算方案。结合核电站安全壳打压试验实测数据,对该研究成果与法国电力公司计算结果进行了比较,最终给出该体积权重计算方法的可行性结论。

Leakage-rate is one of the most important acceptance criteria in the containment test. The weight of volume for the leakeage measurement probe can affect the leakage-rate result. Using the optimization path and analyzing the distribution of temperature and humidity in the containment during CTT test, this paper presents a new method for the calculation of the probe volume used in the calculation of leakage-rate in containment test. At last, this paper calculates the leakage-rate with new volume admeasurement, which is close to the result of EDF.
