核电厂主控制室空气内渗透试验方法
Test method for air inleakage of main control room in nuclear power plants
摘要:
核电厂主控制室空气内渗透作为影响主控制室压力边界完整性的重要因素,目前没有成熟的理论计算方法,只能通过测试得到。通过分析主控制室空气内渗透的试验测试方法以及理论依据,总结适用于现场测试的方法以及各测试方法的特点。结果表明:示踪气体测试法中的浓度衰减法或恒定流量法适用于建造完成的主控制室进行总体内渗透量现场试验,组件测试法有利于发现产生主控制室空气内渗透的主要原因。
Abstract:
As an important factor of the integrality of main control room in nuclear power plants, the air inleakage of main control room can only be tested rather than be calculated theoretically. Presents the test method and theoretical analysis of air inleakage of main control room and concludes the most suitable field test method and the characteristics of each test method. The results show that the concentration decay test method and constant injection test method in tracer gas test method can be applied to the whole air inleakage field test and the component test method can contribute to finding the air inleakage point.
