In May 2019, the reactor facility’s primary circuit equipment complex diagnostics system has been commercially commissioned at unit 4 of ZNPP.
The RF complex diagnostics system provides information on the state of the main equipment of the reactor compartment.
The system is designated for complex monitoring and diagnostics of the main equipment and the pipelines of a WWER 1000 (В-320) reactor facility in the normal operation mode, using the data of the local diagnostics systems, information from the unit’s control computer network and the automated radiation monitoring system.
The new complex system will significantly increase the unit operation safety level – due to online analysis of the state and early detection of the beyond-design states (abnormalities) in the reactor facility’s equipment. It will enable receiving required information to make a decision on possibility to prolong a period of operation, will allow optimizing maintenance planning for RF’s diagnosed equipment.
