[0029] Example: Response time test for shutdown conditions with low core coolant flow rate.
[0030] During the normal operation of the nuclear power plant, the core coolant flow rate is strictly controlled within a certain limit to ensure the safe and stable operation of the reactor. The flow sensor arranged at the hot end of the primary circuit transmits the flow value of the hot end to the reactor protection system in real time. When the reactor protection system detects that the flow value of the hot end is less than the set value, the reactor shutdown will be triggered on the premise that the P10 signal is not blocked. Signal to control the shutdown of the reactor. In order to ensure that the reactor protection system outputs the shutdown signal of low hot-end core coolant flow in time, it is necessary to test the response time of the shutdown function of the reactor protection system for low hot-side core coolant flow.
[0031] After the reactor protection system collec...
