Control rod control system
Control rod control system is an executive part of control and protection system of NPP power units.
Functions of SGIU:
- automatically controlling control rods (CR) movement by signals of protections, an automatic power controller or by operator’s commands;
- indicating current position and state of CRs in MCR and BCR;
- recording, visualizing, and archiving parameters.
System advantages:
Doubling of each channel
Control of different types of drives
Possibility of RO control
Power supply of power equipment with direct current,
Automated support of a physical experiment
A developed diagnostic system
Inclusion of a testing stand for SUZ drives into a supply set.
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.
Normal operation control systems for reactor and turbine divisions
The systems are designed to control normal operation control of NPP units’ technological systems.
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.
