摘要

CP600核电机组的ATWT反应堆保护在实现方式上采用失电动作和带电动作相结合的方式。CP600全范围模拟机对ATWT反应堆保护的带电动作进行了详细模拟,对失电动作进行简化模拟,能够实现正常运行期间的ATWT保护,以及LNE整体失电和恢复供电时对ATWT信号的闭锁,基本能够完成涉及ATWT保护的操纵员模拟机培训课程任务。同时模拟机中的ATWT实现方式存在一定不足,可以进行适当的改进,使得模拟机中ATWT保护现象模拟的更加真实,提高操纵员模拟机培训的效果。
        The ATWT reactor protection of CP600 nuclear power unit adopts a combination of loss-of-power operation and live-action operation. The CP600 full-range simulator simulates the charging operation of the ATWT reactor in detail. A simplified simulation of the power loss operation can achieve ATWT protection during normal operation and block the ATWT signal when the LNE is powered off and power is restored. Be able to complete the operator simulator training course tasks involving ATWT protection. At the same time, the realization of ATWT in the simulator has some deficiencies and can be properly improved, which makes the simulation of ATWT protection in the simulator more realistic and improves the training effect of the simulator.
