Holtec International is disappointed by the outcome of the Great British Nuclear (GBN) Small Modular Reactor (SMR) tender process but extends its congratulations to the selected technology provider.

This decision by GBN means that Holtec’s plans for a significant manufacturing facility in South Yorkshire will now be scaled back in size and jobs while being delayed in terms of timeframe.

Despite the outcome from this competition, Holtec remains resolute in its belief that Holtec’s SMR-300 is among the most advanced, safe, and deployable reactor designs in the world. Our participation in the tender has further reinforced the global interest in our technology, and we are grateful for the opportunity to showcase our capabilities.

Looking ahead, Holtec is intensifying its focus on partnerships with private-sector clients in the United Kingdom that can move at pace and international stakeholders who are seeking proven, scalable SMR solutions. With active engagements in North America, Asia, and other regions, we are well-positioned to bring clean, reliable nuclear energy to a broad range of applications—including industrial decarbonization, grid support, and remote power generation.

Our commitment to innovation, safety, and energy security remains unwavering, and we thank our partners and supporters across the UK for their continued interest in Holtec’s world class technology.
