OF BORON CONCENTRATION MONITORING SYSTEM IS INTRODUCED TO TRIAL OPERATION AT KhNPP

Of boron concentration monitoring system is introduced to trial operation at power unit No. 2 of the Khmelnytsky NPP. Before that, she passed individual and complex tests.

ОThe main function of the NAR-I boron concentration monitoring system based on neutron solution analyzers – automatic continuous measurement of boron-10 (boric acid) concentration in coolant at NPP units with WWER-type reactors. Operating experience at other power units has shown that it provides high measurement accuracy, good reliability of operation under harsh conditions of external factors (gamma radiation, electromagnetic interference, vibration, shock loads, etc.), and is easy to operate.

The system includes:

• 23 neutron analyzers of different types;
• registration and display devices;
• symbol indicators;
• fast neutron sources;
• operator's workplace;
• sets of installation parts, technological and service equipment;
• set of hardware and software metrological support

Acceptance commission determined that the system equipment fully complies with the requirements of the technical specifications, design documentation developed by the Kharkov Institute "Energoproekt" , and decided to accept it for trial operation
