Westinghouse Electric Company has received two contracts from Nuklearna Elektrarna Krško (NEK) to provide a passive containment dry-filter method (DFM) venting system and a passive autocatalytic recombiner hydrogen-control system at the Krško Nuclear Power Plant in Slovenia.
The engineering, design, supply and installation of the two passive safety systems, including aerosol and iodine filter units are scheduled to be complete by April 2015.
“We are proud of our long and steadfast commitment to the safe operation of the Krško Nuclear Power Plant,” said Javier González, Westinghouse vice president and managing director, Southern Europe. “More generally, these contracts reflect the ongoing commitment of Westinghouse to provide the commercial nuclear power industry with products and services that further enhance plant safety and address post-Fukushima lessons learned.”
The fully passive and maintenance-free DFM venting system can effectively depressurize reactor containment while minimizing the release of radioactivity into the environment. Westinghouse said in a statement that the dry filter method offers significant technical advantages over other methods, such as “proven high aerosol and gaseous iodine removal efficiencies; a robust and completely passive process control; high -temperature and high-radiation resistance of all filter components and low maintenance requirements and minimal operating costs.
