核电厂反应堆冷却剂压力边界完整性监测要求的探讨

摘要

The integrity of reactor coolant pressure boundary (RCPB), i. e. , primary loop pressure boundary is closely related to the safety operation of nuclear power plant, the monitoring of the integrity of primary loop pressure boundary is an important job for designing nuclear power plant. Specific requirements of integrity monitoring for primary pressure boundary are proposed in RG 1. 45 -2008, and some of the monitoring methods are recommended. The monitoring requirements of RG 1. 45-2008 are analyzed first, and then the difference with RG 1. 45-1973 is compared, and in accordance with the monitoring method recommended in RG1. 45-2008, the application of this method in domestic nuclear power plant is investigated.%核电厂反应堆冷却剂压力边界(即一回路压力边界)的完整性与核电厂能否安全运行密切相关,对一回路压力边界完整性的监测是核电厂设计的一项重要工作. RG 1. 45-2008对核电厂一回路压力边界完整性的监测提出了具体的要求,并推荐了一些监测方法. 首先分析了RG 1. 45-2008的监测要求,然后对比其与RG 1. 45-1973的差异,并针对RG 1. 45-2008推荐的监测方法在国内核电厂的应用进行探讨.
