SET OF ELECTRIC EQUIPMENT OF NUCLEAR REACTORS CONTROL AND PROTECTION SYSTEM Russian patent published in 2016 - IPC G21C7/36 

FIELD: power industry.

SUBSTANCE: invention can be used in control and protection systems (CPS) of pressurised water reactors (NR). According to the invention the set of the electric equipment of CPS is made in form of blocks of the functional subsystems (FS), including FS of executing part of emergency and preventive protection (EPP); power supply (PS); software and hardware system of group and individual control system (SHS GICS); software and hardware system of information and diagnostic network (SHS IDN) and FS of reactor automatic power regulator (APR), their modules are equipped with the appropriate functional electric equipment. PS EPP is equipped with two independent sets of electric equipment made with the possibility of formation of the executive protection commands (EPC) with their transmission to the equipment of SHS GICS and APR. FSs are functionally linked, and create CPS NR together with other systems. Each set of EPP block contains modules to receive the common signals of the emergency protection and preventive protection; to form EP executive commands; modules with power breakers, and modules to form PP executive commands.

EFFECT: increased reliability and safety of the nuclear reactor operation due to continuous monitoring of all its systems with the possibility of multivariant transition to the optimal operation modes.
