30 Oct (NucNet): The Westinghouse Electric Company has been awarded a contract by Ukraine’s National Nuclear Energy Generating Company Energoatom to provide a passive hydrogen control system for the Zaporozhye-1 and -2 nuclear units, Westinghouse said in a statement.
The contract will see Westinghouse provide the engineering, design, supply and installation of the system by January 2016.
The passive hydrogen control system is designed to provide additional measures for ensuring containment integrity in the event of certain design-basis accidents or beyond-design-basis accidents.
Westinghouse says its passive autocatalytic recombiner, named NIS-PAR, helps to control and mitigate the effects of hydrogen generated under severe accident conditions.
As part of the safety enhancement efforts after the March 2011 Fukushima-Daiichi nuclear station accident, Westinghouse has provided the NIS-PAR system to various nuclear stations in the world, including Krško (Slovenia), Angra (Brazil), Vandellós (Spain) and Kashiwazaki-Kariwa (Japan).
The Zaporozhye nuclear power station has six commercially operational Russian VVER-1000 nuclear reactors with a capacity of 950 megawatts each. It is the biggest nuclear station in Europe in terms of capacity.
Zaporozhye-1 and -2 became commercially operational in 1985 and 1986.
