核电厂通风系统引压管布置的分析与改进

The Analysis and Improvement for the Layout of the Ventilation System Pressure Pipe in Nuclear Power Plant

引压管作为核电厂通风系统的部分,在放射性滞留、包容方面起着关键作用。针对调试过程中发现的压差表控制逻辑错误、过滤器压差读数偏差等缺陷,本文从通风系统引压管布置的角度出发,在理论推导和试验测量的基础上指出了上述缺陷的根本原因,并提出了解决办法。

As a part of the ventilation system in nuclear power plant,the pressure pipe plays an important role in the retention and inclusion of radioactivity.For the errors of the manometer control logic and the reading deviation of filter differential pressure in the commissioning,from the layout of the ventilation system pressure pipe,the paper points out the root cause of these defects on the basis of the theoretical derivation and experimental measurement,and puts forward solutions.
