摘要
示踪气体混合均匀性是执行核电站主控室可居留性内漏试验的关键因素之一,本文通过CFD技术对主控室可居留区域内部示踪气体扩散过程进行数值模拟。根据模拟结果可基本掌握主控室可居留区域内部示踪气体扩散及流场分布情况,针对局部浓度异常区域合理布置气体混合设备,将明显改善示踪气体浓度分布均匀性。
The uniformity of tracer gas mixing is one of the key factors which can affect in-leakage test for nuclear power plant main control room envelope habitability.In this paper,the diffusion process of tracer gas in the residence area of the main control room is numerically simulated by CFD.According to the simulation results,the tracer gas diffusion and flow field distribution in the habitable area of the main control room can be basically mastered.The uniformity of the tracer gas concentration distribution can be significantly improved by reasonably arranging the gas mixing equipment in the area with local abnormal concentration.
