Normal operation control systems for reactor and turbine divisions
The systems are designed to control normal operation control of NPP units’ technological systems.
Functions:
- primarily processing input signals and generating current signals;
- generating commands according to algorithms of technological protections, interlocks, and alarm;
- automatically regulating technological parameters with the possibility to change settings from a workplace of an automated regulating system operator in MCR;
- remotely controlling and indicating states of actuators;
- visualizing, archiving, and logging of current technological and diagnostic information;
- transferring data on values of technological parameters, state of protections, interlocks, and actuators, diagnostic data to unit’s IVS.
Advantages:
High fail-safety
Ergonomic and intuitively
High level of system’s security
Convenience of operation and maintenance
Other solutions for nuclear power plants
Process information system (unit’s upper level)
Central control system for the NPP power unit which provides visualization, registration and documentation of technological process parameters in all operating modes of the power unit, control of critical functions and basic safety parameters.
In-core monitoring system
The in-core monitoring system assures monitoring of neutron-physical and thermohydraulic parameters of a reactor facility’s (RF) primary circuit and information support to an operator.
System to monitor boron-10 isotope (boric acid) concentration
The main function of the boron concentration monitoring system based on neutron solution analyzers NAR-I – automatic continuous measurement of boron-10 (boric acid) concentration in coolant at NPP power units with WWER-type reactors.
Safety control system technological
The system is designed to initiate actuation and control of the power units’ safety systems.
Neutron flux monitoring system
The system is a part of a control and protection system (SUZ) of NPP power units.
Complex diagnostics system for equipment of a reactor facility’s primary circuit
It provides complex technical diagnostics of the primary circuit equipment by analyzing diagnostic information received from power unit monitoring and control systems, local diagnostic systems and its own databases.
