Nuclear plant control system dismantling method, nuclear plant control system

摘要

PROBLEM TO BE SOLVED: To efficiently disassemble a nuclear plant while continuously acquiring necessary sensing signals with a smaller demand for electric power supply.SOLUTION: A nuclear plant control system includes a normal operation controller, a safety system controller and a central controller. A new controller dedicated for reactor abolishment is disposed for performing the control processing of the normal operation controller, the control processing of the safety system controller and the processing of the central controller while inputting sensor signals required for performing reactor abolishment of the nuclear plant in the sensor signals which are input to the normal operation controller and the safety system controller.SELECTED DRAWING: Figure 1
