摘要

摘要: 安全壳整体性试验是核电机组建设与在役期间最重要的大型综合性专项试验项目，具有风险高、工艺复杂、占用大修关键路径时间长的特点。而提高充压速率是缩短大修工期，提高机组经济能力的一种有效途径。而提升充压速率后，是否会引起安全壳内部气体稳定时间增加，还应进行充分的研究与论证。为此以M310堆型为对象，采用计算流体动力学模拟安全壳整体性试验过程，分析充压速率分别为15 kPa/h和40 kPa/h时安全壳内部压力场、速度场及温度场的变化规律，研究充压速率对安全壳内部气体稳定时间的影响。计算结果表明，当充压速率提高至40 kPa/h时，安全壳内部气体稳定时间略有增加，但达到试验压力4 h后，安全壳内的气体已经基本稳定。

Abstract: The pressurization test of containment, which has the characteristics of high risk, complex process and long holding time, is one of the most important special projects during construction and operation period. For the sake of increasing the economy capacity units and saving the maintenance time, an effective approach is to increase the pressurization rate. However, the approach is likely to cause the increase of the stability time of air in containment and the decrease of the accuracy and reliability of the containment leakage test. Therefore, it is necessary to study the influence of the increase of pressurization rate on the stability of air. Taking the M310 reactor as an example, the theory of computational fluid dynamics was adopted to simulate the whole process of the pressurization test. When the rate of pressurization was 15 kPa/h and 40 kPa/h, the variation of the internal pressure, velocity and temperature of the containment was analyzed, and the influence of the pressurization rate on the stability of air in containment was investigated. It was shown by the results that if the rate of pressurization was raised to 40 kPa/h, the internal air of the containment was stable after reaching the test pressure for 4 h.
