SMRs & ADVANCED REACTORS | ROSATOM’S SMR PLAY
Russia bets big on small reactors
Rosatom already commands a substantial slice of the GW-scale nuclear power plant export market. Now it is focusing on the small and
micro reactor sector too where it intends to become the only nuclear vendor in the world capable of meeting demand for plants of any size
By Leo Kaplan et al
WITH AN OVER 80% MARKET share, Rosatom has secured an almost unassailable position in the world’s new-build exports of GW-scale reactors. Now it is working towards extending its market reach with in the small- and medium- capacity reactor segment too. The development of small modular reactors (SMRs) is one of the key components of Russia’s nuclear energy strategy to 2050. The main role of SMRs in the context of future deployment in Russia is to power remote regions, including the vast and scarcely populated lands of Siberia and the Russian Far East, which lack extensive power transmission lines. They are also expected to provide electricity for energy-intensive industries like mining and to serve as emergency autonomous power sources for larger grids, thereby enhancing energy security. For export markets Russian SMRs would also target potential on-grid
applications for countries and regions with smaller size grids, as well as regions currently heavily dependent on coal for electricity supply, as well as district heating, which are moving towards decarbonisation of their grids.
Portfolio approach Rosatom has developed a portfolio of designs both for use in Russia and potential export, covering a broad spectrum of applications and market segments. It includes the RITM series of reactors for plants with the total capacity ranging from 50 to 600 MWe, Shelf-M reactors for off-grid installations covering less than 10MWe to 50 MWe, and the generation-IV SVBR-100 lead-bismuth-cooled fast reactor. The RITM-200 series, based on an evolutionary generation
III+ integral PWR design, is already in series manufacturing. Already 10 RITM-200 reactors have been manufactured
