CONTROL DEVICE, AND NUCLEAR POWER PLANT CONTROL SYSTEM

摘要

A nuclear power plant control system 1 includes control devices 30a and 30b, and the control devices 30a and 30b each include arithmetic units 32a and 32b that respectively execute arithmetic processing in parallel independently, based on detection results of detection units 10a to 10d, and each output a control signal to control a countermeasure unit 40a or 40b in accordance with an arithmetic result of the arithmetic processing, a transmission unit 33 that sends out the control signal to the countermeasure unit 40a or 40b, when the control signal is outputted from at least one of the arithmetic units 32a and 32b, and a system management unit 34 that performs control so as to inhibit the control signal outputted by the arithmetic unit as a test object from being sent out from the transmission unit 33 while maintaining a state where the other arithmetic operation executes the arithmetic processing independently, when a test of either of the control devices 30a and 30b is conducted.
