SGE, GE Vernova, Hitachi and Samsung C&T sign MoU to deploy BWRX-300 SMRs in Europe and UK
An agreement was signed in September 2026 by SGE, GE Vernova, Hitachi. Samsung C&T to explore the deployment of the BWRX-300 small modular reactor (SMR) in Europe and the United Kingdom, with SGE as regional lead. The MoU outlines cooperation to assess markets, regulatory needs, and deployment opportunities, under a diplomatic framework involving high-level government officials.
What the agreement covers
The memorandum of understanding (MoU) formalizes a cooperative pathway among SGE, GE Vernova, Hitachi. Samsung C&T to study and potentially deploy the BWRX-300 SMR, a nuclear reactor designed to be smaller (about 300 megawatts) and modular compared with traditional reactors. The plan focuses on Central and Eastern Europe and the United Kingdom. The signing event occurred in New York during a Nuclear Energy Policy Summit beside the United Nations General Assembly, signaling a high-profile, diplomatic tone.
Key facts to know
The BWRX-300 is a type of small modular reactor (SMR) that produces about 300 megawatts of electric power. SMRs are designed to be built in factories and installed in smaller units, with potential cost and siting advantages compared with large reactors. The MoU is a non-binding agreement that establishes cooperation for market study, regulatory review, and joint planning; it does not itself authorize construction or operation. Government officials from the United States and Japan attended the signing, indicating international-level diplomatic engagement in the project.
Who is affected
Potentially affected groups include energy regulators in Europe and the UK, utility developers, local communities near potential deployment sites, and workers in the nuclear and construction sectors who could be involved in future projects. The immediate effect of the MoU is to set a cooperative framework; it does not impose immediate changes to energy policy or plant construction. Public safety and environmental oversight would still be governed by national and regional rules if a project advances to planning and licensing.
Practical next steps
What to watch next is development of market studies, regulatory assessments, and early site evaluations. If the parties move toward actual deployment, steps would include: detailed site screening, environmental impact reviews, securing permits, financing arrangements, and construction planning. Officials may provide updates on timelines and any potential public consultations. For the public, remain informed through official regulatory bodies and company disclosures; no new reactors are approved by this MoU alone.
