摘要: 基于AP1000核电厂主控室(MCR)的密封性设计及非能动应急通风设计特点,探讨适合于AP1000主控室内漏示踪气体试验的方法和理论,并对试验结果和难点进行分析。结果表明:恒定注入法作为AP1000主控室内漏示踪气体试验的优选方案,其试验理论成熟、可操作性强、计算精度高,可以较好地满足AP1000非能动设计的验证要求。Abstract: Combining with the sealed design of AP1000 MCR and passive design of MCR ventilation systems,this paper explores the method and theory which is suitable for AP1000 main control room inleakage tracer gas test and anticipates the test results and difficulties.Results show that the constant injection test is the preferred method for AP1000 main control room inleakage tracer gas test.The constant injection test based on mature theories and with strong operability and high precision,can well meet the AP1000 passive design verification requirements.
