Warsaw – On April 1, 2026, SGE, Polimex Mostostal, and ATEC Group signed a Memorandum of Understanding (MoU) to cooperate on the development and deployment of small modular reactors(SMRs) in Central and Eastern Europe. The agreement focuses on implementing the world’s most advanced commercially available SMR technology – the BWRX-300, developed by GE Vernova Hitachi Nuclear Energy. SGE is currently advancing partnerships and projects based on the BWRX-300 across more than half a dozen European countries.
The MoU aims to facilitate collaboration between the companies and establish working groups to jointly explore potential projects in Central and Eastern Europe. These activities will include identifying areas of synergy and assessing the companies’ competencies and organizational capabilities in the context of delivering nuclear projects.
The signing of the MoU underlines the continued commitment of Polimex Mostostal, SGE, and ATEC to the development of nuclear energy and the strengthening of the supply chain for SMR projects in Poland and across the region.
“We are developing a coherent SMR deployment model in Central and Eastern Europe that combines access to proven BWRX-300 technology with strong local construction and industrial capabilities. Our agreement with Polimex Mostostal and ATEC strengthens our ability to scale projects across the region and build an efficient supplier ecosystem. Our goal is to deliver repeatable, financeable nuclear projects that will support the energy transition and enhance energy security across the region” said Rafał Kasprów, CEO of SGE.
“Signing the MoU with SGE and ATEC is an important step in building partnerships for the delivery of SMR projects in Central and Eastern Europe. The agreement provides a framework for defining potential areas of cooperation and identifying where we can leverage our experience in delivering large-scale industrial and energy projects. At the same time, it enables the complementary use of each party’s strengths in the development of SMR projects. We see significant potential in this technology and want to actively participate in building the supply chain for this type of investment” saidJakub Stypuła, President of the Management Board, Polimex Mostostal.
“ATEC is consistently expanding its engineering capabilities in the nuclear energy sector. We are very pleased to be working with Polimex Mostostal, the largest and most important EPC contractor for energy projects in Poland, and we see strong potential in deploying the proven BWRX-300 technology in our country for two reasons. First, Poland needs nuclear energy to stabilize its power system, which must also rely on stable sources of energy and on reliable, low-emission technologies capable of keeping the grid operating under adverse conditions. Nuclear energy is today the only scalable option that can simultaneously provide resilience, decarbonization and strategic autonomy. If we want to carry out an energy transition that is not only green, but also credible and capable of delivering acceptable energy prices, nuclear energy must return from the margins to the center. Second, the SMR project represents a unique opportunity to create a truly local supply chain, of which, together with Polimex Mostostal, we want to be an important part. This is an exceptional opportunity for our companies, and one we cannot afford to miss” said Maciej Stańczuk, Member of the Management Board of ATEC Group.
The cooperation between SGE, Polimex Mostostal, and ATEC aligns with the long-term strategies of all parties, focused on developing nuclear energy in Central and Eastern Europe and effectivelyleveraging existing expertise in the execution of SMR projects.
