压水反应堆PING监测道取样系统模拟设计

Design Simulartion of PING Monitoring Sampling System in Pressurized Water Reactor

为了保证压水堆PING监测道取样具有代表性,对空气动力学直径为10μm的气溶胶粒子透过率不小于50%。利用Deposition2001a软件模拟气溶胶在取样系统中的透过率,对碘的沉积规律进行了讨论,获得了在一定条件下ACP1000压水堆PING监测道取样系统的优化设计方案,可为其他堆PING监测道取样系统设计提供参考。

In order to ensure the sampling representative of PING monitoring channel of pressurized water reactor,it requests the transmission ratio of sampling system should be more than 50% for 10 μm aerodynamic diameter（ AD） aerosol. In the paper,the aerosol transmission ratio of sampling system is simulated by Deposition2001 a software. In addition,the factors affecting the iodine deposition are discussed. Finally,we acquire the optimization design in the certain condition for ACP1000 PWR PING monitoring sampling system. The research method is available for PING monitoring system design in other reactor types.
