Samsung C&T Engineering & Construction Group has entered into an agreement with Synthos Green Energy, Poland’s leading private developer of Small Modular Reactors (SMRs), to support the deployment of these technologies at a regional scale. The memorandum of understanding, signed in Seoul, covers the implementation of the country’s first SMR project and cooperation in neighbouring markets across Central and Eastern Europe.
One of the most ambitious private nuclear programmes in Europe
Synthos Green Energy is currently leading Poland’s national SMR initiative, aiming to commission up to 24 units of the BWRX-300 model by the early 2030s. This 300-megawatt boiling water reactor, designed by GE Vernova Hitachi Nuclear Energy, uses a standardised modular system to reduce construction timelines. The company also plans to expand its projects into Czechia, Hungary, Lithuania, Bulgaria, and Romania.
The partnership enables Samsung C&T to become part of one of the continent’s largest private nuclear development programmes. The cooperation includes feasibility studies, site analyses, and environmental impact assessments to prepare for SMR deployment in Poland and beyond.
Samsung C&T’s expanding European strategy
This agreement adds to Samsung C&T’s recent nuclear initiatives across Europe. In Romania, the company signed an agreement in 2023 with NuScale and Fluor, and began front-end engineering work in 2024. In Estonia, a memorandum was signed in April with Fermi Energia, and in Sweden, cooperation was launched with Kärnfull Next AB in December of the same year.
These partnerships support the South Korean group’s strategy to anchor itself in Europe’s reshaping nuclear market. The projects aim to meet growing demand for more stable and predictable low-carbon energy sources in a region shifting away from coal under energy security constraints.
Technology alliance with GE Vernova Hitachi Nuclear Energy
Samsung C&T also formed a strategic alliance with GE Vernova Hitachi Nuclear Energy in October to explore SMR opportunities in regions such as Southeast Asia and the Middle East. This alliance is part of the company’s broader plan to internationalise its nuclear portfolio using the BWRX-300 technology already selected by operators like Ontario Power Generation in Canada and Vattenfall in Sweden.
According to Samsung C&T President and CEO Se-chul Oh, this cooperation with Synthos Green Energy represents “a key milestone in establishing the company’s entry into the Polish and wider Central and Eastern European market.” SGE CEO Rafał Kasprów stated that the agreement strengthens Poland’s SMR project by combining “technical expertise with local market knowledge.”
