NPP Equipment Modernization Program:

Power Supply Equipment of Control and Protection

System (CPS) Control Elements

Power Supply Equipment of Control and Protection System (CPS) Control Elements is designed for the following: 

  • Power supply of CPS control elements with three-phase 220 V AC and 110 V DC by executing control and auxiliary functions in the design operation modes at power units of nuclear power plants with VVER reactors;
  • Shutdown of CPS control element power supply under the emergency protection commands received from any two sets of the emergency protection system;
  • Discrete signal generation and output when feeding voltage parameters are violated, which initiates emergency protection actuation in each of three channels of the first and second emergency protection set.
