摘　　要：报警系统对于防止低温供热堆事故工况的发生及事故的扩大具有重要作用.核电厂传统的报警系统存在着报警雪崩等缺陷.200MW低温供热堆报警系统一方面采用可编程控制器(PLC)改进报警系统的传统功能;另一方面利用计算机技术及CRT显示技术,提高报警的智能化程度,提高了报警系统的可靠性,大大增强了报警功能,改善了人机接口,从而提高低温供热堆的运行安全性.The Alarm System plays an important role in keeping the Low Temperature Heating Reactor (LTHR) from incident and deteriorating to severe accident. Conventional alarm systems in the nuclear power plant suffer from defects of alarm avalanche etc. The alarm system in the 200MW LTHR employs the Programmable Logic Controller(PLC) for the improvement on conventional alarm functions and take advantages of computer technique and the ability of color graphic display of CRT to alarm intelligence as well. So the relilability of the alarm system can be raised, and its alarm functions will be essentially enhanced. This would greatly improve the man-machine interface of the control room, leading to higher level of safe operation of 200MW LTHR.
