March 4–5, 2026, important Factory Acceptance Tests were performed at Promviteh LLC in Kyiv for the Check Valve Position Indication System, designed for the Engineered Safety Features Actuation Systems (ESFAS-1 and ESFAS-2) of Power Unit No.4 at the Rivne Nuclear Power Plant. The inspections confirmed that the system is fully ready for further implementation at the plant.
The Check Valve Position Indication System is a key component of the digital Engineered Safety Features Actuation Systems, as it ensures precise position control of the check valves. These data enable real-time monitoring of equipment status and ensure the stable and safe operation of the power unit.
Radiy’s specialists contributed to the preparation of technical documentation and provided expert support for the project. Radiy has a comprehensive engineering and testing infrastructure, including specialized proving grounds and certified laboratories. Our experts regularly become part of testing committees or provide full support for equipment testing, ranging from qualification tests to final acceptance tests, and so on.
Radiy’s specialists provide a detailed analysis of the systems’ compliance with technical requirements, functional specifications, and operational documentation during testing. The results of these inspections confirm that the equipment is functioning properly and is ready for use at critically important power facilities.
Every element of the system is important for the energy sector, and especially for the nuclear power industry. The successful testing of the Check Valve Position Indication System once again confirms that Radiy’s expertise in testing and engineering support ensures a high level of reliability, safety, and technological readiness for contemporary energy solutions.
