- Samsung C&T Engineering & Construction (E&C) Group has signed with Poland’s Synthos Green Energy (SGE) to collaborate on Small Modular Reactor (SMR) development, including Poland’s first SMR project and future expansion across Central and Eastern Europe
- The partnership strengthens Samsung C&T’s growing SMR portfolio in Europe, following recent collaborations in Romania, Estonia, Sweden, and a strategic alliance with GE Vernova Hitachi Nuclear Energy
Samsung C&T E&C is further accelerating its expansion into Europe’s clean-energy market through a new partnership with SGE, Poland’s leading private-sector SMR developer. The Group has signed a memorandum of understanding (MoU) with SGE to advance SMR development in Poland and expand cooperation across Central and Eastern Europe. The agreement, signed on December 11 in Seoul with SGE Chairman Michał Sołowow, CEO Rafał Kasprów, and Samsung C&T President and CEO Se-chul Oh in attendance.
Driving Poland’s First SMR and a 24-Unit Deployment Plan
SGE is leading Poland’s national SMR initiative and plans to deploy up to 24 units of the BWRX-300—a next-generation Small Modular Reactor—by the early 2030s, including the country’s first SMR power plant. The company also aims to expand SMR projects into Czechia, Hungary, Lithuania, Bulgaria, and Romania, reflecting the region’s increasing demand for stable and sustainable low-carbon energy solutions.
The BWRX-300, developed by GE Vernova Hitachi Nuclear Energy, is a 300-MW boiling water reactor (BWR) SMR designed to enhance construction efficiency through modularization and simplified systems. The technology is already advancing toward deployment: construction is underway at Ontario Power Generation in Canada, the first SMR project in the Western market to enter the build phase, and Sweden’s state-owned utility Vattenfall has selected the BWRX-300 as the final candidates for expansion at the Ringhals nuclear site.
Through this partnership, Samsung C&T becomes part of one of Europe’s largest private-sector SMR development programs, positioning the Group to contribute to long-term energy transition efforts across Central and Eastern Europe. Under the MoU, the two companies will carry out feasibility studies, site assessments, and environmental impact evaluations to prepare for Poland’s SMR rollout and potential expansion across the region.
Expanding Samsung C&T’s SMR Footprint Across Europe
With this latest partnership in Poland, Samsung C&T is further strengthening its European SMR portfolio that has rapidly expanded in recent years.
Romania
• Jun 2023: Signed an MoU with the Romanian Nuclear Energy Corporation, NuScale, Fluor, and other partners for SMR cooperation and broader European market development.
• Jul 2024: Began FEED (Front-End Engineering Design) work for Romania’s SMR project.
Estonia
• Apr 2024: Signed an MoU with Fermi Energia, Estonia’s private nuclear company, to collaborate on SMR project development.
Sweden
• Dec 2024: Signed an MoU with Kärnfull Next AB for SMR cooperation in Sweden.
Poland
• Dec 2025: Signed an MoU with Synthos Green Energy for SMR development in Poland and across Central and Eastern Europe.
Advancing Europe’s Clean-Energy Goals Through Collaboration
Samsung C&T E&C’s broader strategy in next-generation nuclear development also includes a strategic partnership formed with GE Vernova Hitachi Nuclear Energy in October 2025 to pursue SMR opportunities across Europe, Southeast Asia, and the Middle East. Together with its new cooperation with SGE, these efforts reflect the Group’s goal of strengthening its role as a key SMR development partner in major global markets.
Samsung C&T President & CEO Se-chul Oh stated that “close cooperation with Synthos Green Energy will serve as a key milestone in securing Samsung C&T’s entry into Poland and the wider Central and Eastern European region.”
SGE CEO Rafał Kasprów highlighted that combining Samsung C&T’s global nuclear project capabilities with SGE’s business expertise “enhances the potential for Poland’s SMR development and supports the delivery of safe, sustainable energy solutions across Europe.”
