REACTOR PLANT EMERGENCY PROTECTION SYSTEM Russian patent published in 2024 - IPC G21C7/36 

FIELD: control and regulation.

SUBSTANCE: invention relates to a system for automated monitoring and control of nuclear power plants. System has a four-channel initiating part, an actuating part, characterized by that automation processor PA-1, located in the collection and processing cabinet of each of the four channels of the initiating part, is configured to transmit signals to equipment located in the emergency command cabinets ECC-1 and ECC- 2 executive part. Automation processor PA-2 arranged in the collection and processing cabinet of each of the four channels of the initiating part is configured to transmit signals to the equipment located in the emergency command cabinets of the ECC-3 and ECC-4 of the actuating part. At that, equipment of each of cabinets of emergency commands ECC-1, ECC-2 is made with possibility of formation of executive commands for actuation of protection and their transmission via wire communication interfaces to equipment located in cabinets of power breakers CPB-1 and CPB-2. Equipment of each emergency command cabinet ECC-3, ECC-4 is configured to generate executive commands for actuation of protection and their transmission via wire communication interfaces to equipment located in cabinets of power breakers CPB-3 and CPB-4.

EFFECT: providing emergency shutdown of the reactor with a single-set four-channel design of the initiating part of the emergency protection and the given organization of interconnections between the initiating and actuating parts of the emergency protection even in case of malfunction of the equipment of diversion or failure of programmable means for a common reason.
