The Kolsk NPP became the first one in Russia to try the unique technology of steam generators’ welded connections operational life extension
The one-of-a-kind technology of steam generators’ welded connections operational life extension on VVER-440 reactors has been trialed at the Kolsk NPP’s 2nd power block as a part of the preventive maintenance activity taking place on September 16-21, 2016. On September 19th, the company’s foreign partners from Fortum*, a power generating company from Finland, familiarized themselves with this technology.
The Kolsk NPP has been working on this operational life extension technology for the last 10 years, starting those activities back in 2007. As of now, 21 steam generators’ headers have already been restored. The thing that makes this method unique is that an autowelding complex was used during the works. Prior to that, autowelding was never used for fixing the headers at such types of steam generators. The Kolsk NPP deserves its title as the leading one in implementing new technologies for power block’s operational life extension.
Vladimir Dementiev, the chief technologist of Rusatom Service (the company delivering services to NPPs abroad), said: “The Kolsk NPP is the world’s first nuclear power plant to embrace this unique technology of extending steam generators’ operational life span using autowelding. As of now, the operation power blocks all over the world are working on prolonging their life span, including those based in Europe and operating the reactors similar to the ones running at the Kolsk NPP. A good example is the Loviisa NPP based in Finland”.
The new methodology trialed at the Kolsk NPP can be used for similar activities at the Loviisa NPP, if necessary.
OKB “GIDROPRESS”, CNIITMASH, and the Rosenergoatom Concern delivered technical support during the process of welded connection restoration using autowelding.
* Fortum is a major electric power concern in the Northern Europe (Finland and Scandinavia), Russia, and the Baltic Sea Region. The company generates, transfers, and sells electric power and heat, as well as provides services on electric power stations’ operation and technical maintenance. Fortum accounts for 3000 megawatts (electric power) of the nuclear power capacity in Finland and Sweden, including the Loviisa NPP.
The Kolsk NPP is an affiliate of Rosenergoatom Concern JSC and is based 200 km to the south from the city of Murmansk, at the Imandra lakeside. The plant produces around 60% of the Murmansk Region electric power. It has 4 operational power blocks with VVER-type reactors, each of them having capacity of 440 megawatt. The Kolsk NPP supplies electric power to the Murmansk Region and Karelia.
