This week ( 04.07. – 15.07.), a factory test was carried out on the new Novovoronezh nuclear power plant’s main cooling system actuator, which, by the way, has several times bigger output than, for example, the Krško nuclear power plant. Representatives of Rosatoma are very satisfied with the technical solution and the performance of the HYDROMAT actuator system. The MIV Varaždin butterfly valves and construction and production actuators HYDROMAT Ivanec, currently in the world, provide the best solutions in extremely demanding application areas such as the main nuclear power plant’s cooling systems.
