核电厂一回路松脱部件监测系统法规标准研究

摘要

针对核电厂一回路松脱部件监测系统国内外相关法规标准进行了研究,并从系统功能、监测区域、测点布置、报警原则及抗震等级要求等方面进行比较分析,在此基础上提出核电厂一回路松脱部件监测系统典型设计方案. 该方案满足系统的国内外法规标准要求,为后续新项目核电厂一回路松脱部件监测系统设计提供思路.%Related regulations and standards for monitoring systems of the loose parts in primary loop of nuclear power plants are researched, and various aspects including system functions, monitoring areas, layouts of measuring points, alarm principle and aseismic rating, etc. , are compared and analyzed. On this basis, the typical design scheme of the monitoring system for the loose parts of primary loop is proposed. The scheme satisfies the requirements of the regulations and standards at home and abroad, and provides design ideas for such monitoring systems of subsequent new nuclear power projects.
