Story details
SGE, GE Vernova, Hitachi and Samsung C&T have signed a memorandum of understanding to explore market development and commercial opportunities for deployment of the BWRX-300 small modular reactor in Central and Eastern Europe and the United Kingdom. GE Vernova’s September 22 announcement says the agreement was signed in New York during the Atlantic Council Nuclear Energy Policy Summit, held alongside the United Nations General Assembly. The statement sets a framework for possible regional cooperation.
Under the memorandum, the companies intend to assess markets, develop deployment strategies and pursue commercial opportunities. GE Vernova Hitachi Nuclear Energy is the BWRX-300 designer and technology provider; Hitachi contributes nuclear technology and industrial expertise, while Samsung C&T brings engineering and construction capabilities. SGE acts as a European development platform and regional lead. The announcement does not identify a construction contract for a new plant in any country, a final investment decision or a construction permit.
The companies describe the BWRX-300 as a 300-megawatt reactor. Their stated ambition is to combine technology, supply-chain and project-delivery capabilities across more than one market. They say standardization could support repeat deployment, but the release gives no project-specific cost, financing package, construction timetable or electricity price.
SGE says Poland has decisions in principle for 26 BWRX-300 units and that current development work focuses on three sites with potential to host the first 14. In the United Kingdom, it is advancing a proposed 4.2-gigawatt fleet of 14 reactors across three multi-unit sites. The proposal has entered the Preliminary Regulatory Assessment Deep Dive led by Great British Energy–Nuclear. These figures describe SGE’s development pipeline; they are not permits or firm orders granted under the new memorandum.
The announcement illustrates how reactor technology, licensing work, supply chains and construction partners may be assembled before a fleet is built. The four companies will explore options in Central and Eastern Europe and the UK, while regulatory reviews and commercial decisions will remain separate for each site. The memorandum therefore does not establish that any additional reactor will be built. Concrete next steps would include named project proposals, permit applications, binding contracts or investment decisions.
