The reliability of pumping units at nuclear power plants (NPPs) is critical in terms their energy efficiency and safety. Remarkably, WWER-1000 reactors Ukrainian NPPs are equipped with outdated that have already served full-service life. This fact leads to an urgent need develop a new, more efficient pump. In the article, promising pump, ACNA 600-35, was developed. It designed increase pumps TX...
