| 摘要: |
| 为提高恒压法安全壳泄漏率测量技术的成熟度,评估恒压法安全壳泄漏率理论模型的适用性与可靠性,提出了标况均值法和工况均值法理论分析模型。理论模型的验证须在壳内压力恒定的环境下获取壳内气体参数并计算泄漏率。首先,在自由容积1 000 m3的钢制安全壳模拟体内布置传感器监测壳内气体状态,并在充气管路上设计流量调节装置维持壳内恒压,分别在正压和负压环境下开展实验,探究了应用标况均值法和工况均值法计算安全壳泄漏率的稳定性和一致性。其次,应用恒压法理论模型分析某核电厂压降法试验获取的工程数据,探究了恒压法理论模型对工程尺度安全壳的适用性和对压降法的包容性。研究结果表明:两种恒压法理论模型计算的安全壳泄漏率具有较好的一致性,相对偏差小于±0.2%；工程尺度试验数据分析中恒压法理论模型计算的泄漏率可以达到压降法的精度,两种方法之间相对偏差不足5%,恒压法理论模型可用于分析压降法试验数据。本研究成果可为恒压法安全壳泄漏率测量技术的理论研究和工程应用提供支撑。 |

| Abstract: |
| To improve the maturity of the containment leakage rate measurement technology, this study evaluates the applicability and reliability of the theoretical model of constant pressure method for containment leakage rate. Two theoretical analysis models, namely the standard condition mean method and the operating condition mean method were proposed. The validation of the theoretical models requires the acquisition of gas parameters within the containment under a constant internal pressure environment, followed by the calculation of the leakage rate. Firstly, sensors were arranged in the simulation body of steel containment with a free volume of 1 000 m3 to monitor the gas status, and a flow regulation device was designed in the inflation pipe to maintain constant pressure. Experiments were carried out in the environment of positive pressure and negative pressure. The stability and consistency of the containment leakage rate calculated by means of standard conditions and working conditions were explored. Secondly, the data from engineering test of pressure drop method in a nuclear power plant were analyzed by using the theoretical model of constant pressure method. The applicability of the theoretical model of constant pressure method to engineering scale containment and its compatibility with pressure drop methods were explored. The study indicates that the two theoretical analysis models have good consistency in calculating the containment leakage rate, with a relative deviation of less than ± 0.2%. The leakage rate calculated by the theoretical model of constant pressure method can achieve the accuracy of the traditional pressure drop method, with a relative deviation of less than 5% between the two methods. Therefore, the theoretical model of constant pressure method can be used to analyze the test data of pressure drop method. The findings of this research can provide support for the theoretical research and engineering application of the constant pressure method for containment leakage rate technology. |
