AUXILIARY CONTROL METHOD FOR NUCLEAR POWER PLANT OPERATION, AND DEVICE AND SYSTEM THEREFOR

摘要

An auxiliary control method, control device and system for nuclear power plant operation, said method comprising: logging in to a nuclear power plant auxiliary control system; sending, by means of the auxiliary control system, a command to shut down the main control system of the nuclear power plant; execution by the main control system of shutdown operations according to said command. Transmission by an auxiliary control system of a command to shut down the main control system of the nuclear power plant avoids, under emergency conditions when control has been lost, the entry by unauthorized persons to the main control room and to workstations of operational personnel to execute illegal operations jeopardizing the safe operation of the plant.
