核反应堆非保护信号停堆自动检测报警装置设计

核反应堆非保护信号停堆自动检测报警装置作为反应堆保护装置的补充，用于及时有效地检测多种非保护信号引起的停堆，实现在核反应堆发生控制棒落棒故障的第一时间发出声光报警信号，提醒操纵员发现故障，并及时进行处置，从而提高核动力装置运行的安全性。本研究采用 STM32系列 ARM处理器，设计了某核反应堆非保护信号停堆自动检测报警装置，通过实验测试，结果表明设计方法可行。

Design of Automatic Detection and Alarm Device for Nuclear Reactor Non-Protection Signal Shutdown

Acting as a complement of the nuclear reactor protection device,the automatic detection and a-larm device for nuclear reactor shutdown is used for timely and effective detection of shutdown caused by a variety of non-protection signal,and producing sound and light alarm when control rods scram occurs.By this way,the operators can find the fault and take action to treat the accident timely,so as to improving the operation safety of nuclear power plant.The nuclear reactor non-protection signal shutdown automatic de-tection and alarm device was designed,in which the STM32 series ARMprocessor was adopted.After tes-ting,the result shows that the design is feasible.
