摘　　要：对核电站反应堆一回路采用湿敏法进行泄漏事故监测,以便尽快给出泄漏规模及位置。采用专门研制的湿敏元件,并以此组合设计成监测探头。测量数据采集、处理及报警系统采用单板机进行巡回监测,并进行本系统所定义的A、B、C参量处理。B、C值同时超过预先设置的限值后,系统发出泄漏报警。参量设置考虑环境湿度及温度的影响。在320℃、12.2MPa下,水的泄漏率为0.3g/min时,5s内发出报警。The paper describes a system concerning the leakage of nuclear power station primary loop. Thesensor of leak--detection system is a special humidity--sensitive element. In this system,the collection andtreatment of detected data,and the alarm of leakage are controlled by a simple board computer. Thethree parameters A, B and C are set up in this system, and the alarm will give out when signal surpassesvalues of B and C at the same time. The effects of environment humidity and temperature on collectionof detected data are considered, and the alarm of leakage is reliable. When the leakage rate of water at320℃ and 12. 2 MPa is 0.3g/min, the alarm signal will sent out within 5s.
