System to record important operation parameters
The system is designated to store and provide personnel with information on parameters of NPP power units in accident and post-accident conditions of design and beyond design accidents.
Functions:
- acquiring information from systems-data sources;
- recording and storing information in a long-term archive;
- providing personnel with information on parameters of NPP power units in a form of diagrams and videograms.
Advantages:
Use of a highly-reliable approved radio channel
Implementation of data exchange between components
High fail-safety of the system
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.
