GE Vernova Hitachi Nuclear Energy (GVH) and Samsung C&T have announced a strategic alliance to accelerate the international deployment of the BWRX-300 small modular reactor (SMR) across markets outside North America. The partnership will focus on developing supply chain and project delivery frameworks for the advanced reactor technology, with particular attention to the potential installation of five BWRX-300 units in Sweden.

"With the first unit of our BWRX-300 under construction in Canada, we are well positioned to lead the deployment and scale of the SMR industry," said Mavi Zingoni, CEO Power, GE Vernova. "This collaboration with a leading player like Samsung C&T, which has a solid track-record of helping to deliver nuclear projects safely, on-time and on-budget, will further strengthen the BWRX-300 position among the most advanced, deployment ready, and lowest risk SMR technology available today."

Samsung C&T CEO Se-chul Oh added, "This agreement marks a strategic collaboration where Samsung C&T and GVH aim to become global leaders in the nuclear power segment. The collaboration will capitalize on Samsung C&T's extensive experience in nuclear power and infrastructure project execution, combined with GVH's validated technological expertise."

Construction of the first BWRX-300 is underway at Ontario Power Generation's Darlington site in Canada, with completion expected by the end of the decade, making it the first operational SMR in the Western world. Major components such as the reactor pressure vessel are in fabrication, and construction activities remain on schedule.

In parallel, the U.S. Nuclear Regulatory Commission is reviewing Tennessee Valley Authority's application to construct a BWRX-300 at the Clinch River site in Oak Ridge, Tennessee, while Orlen Synthos Green Energy has selected Wloclawek as the location for Poland's first SMR. In Sweden, Vattenfall has shortlisted the BWRX-300 for possible deployment near its Ringhals plant on the Varo Peninsula.

Each BWRX-300 delivers approximately 300 MW of electricity - enough to power 300,000 homes - while reducing the complexity and capital requirements typically associated with large-scale nuclear projects.

Samsung C&T's Engineering and Construction Group brings more than four decades of global project experience across infrastructure, energy, and nuclear sectors. Its portfolio includes landmark achievements such as the Burj Khalifa, the Riyadh Metro, the Qurayyah 4,000 MW combined-cycle plant, and the Qatar 2,000 MW solar project. The company has contributed over 12 GW of nuclear capacity across 10 reactor units, including the 5.6 GW Barakah Nuclear Power Plant in the UAE, and continues to expand its expertise through SMR refurbishment and front-end design projects worldwide.
