In the framework of the ANPP outage and life extension activities a scheduled general overhaul of 12 safety valves of the steam generators has been performed. The work was carried out jointly by the Bopp&Reuther service engineer and the ANPP specialists.  Just like the previous major overhaul, which was performed in 2011, this work will also enable to operate the steam generator safety valves in a fail-safe manner within 10 years more.
