WASHINGTON, D.C. (February 24, 2026) – GE Vernova Hitachi Nuclear Energy (GVH) and Orlen Synthos Green Energy (OSGE) have signed an agreement to move forward with the development of a generic design for the BWRX-300 small modular reactor (SMR) in Poland. The Poland Generic Design Agreement (PGDA) was formalized during a ceremony in Washington, D.C., attended by James Danly, Miłosz Motyka, and Wojciech Wrochna, along with representatives from GVH, OSGE, and Synthos Green Energy.

Following the agreement, OSGE will fund the development of a detailed BWRX-300 design that will serve as a standardized reference for future SMR deployments across Poland.

“This agreement highlights the continued commitment of the United States to strengthening Poland’s energy security,” Danly stated. “Our intergovernmental cooperation framework provides a strong foundation for expanding civil nuclear collaboration and supporting new public-private initiatives.”

“Poland has the potential to emerge as a leader in small modular reactor technology in Europe,” said Motyka. “This agreement marks another significant step in that direction. To ensure a stable, zero-emission power system and predictable market conditions, we are developing both large-scale nuclear projects and SMRs in parallel. SMRs will provide reliable baseload power for energy-intensive industries, help stabilize electricity prices, and support the growth of the domestic nuclear supply chain. Given rising electricity demand, both technologies are essential.”

Wrochna emphasized the strategic importance of the initiative: “The development of a generic design is a cornerstone for creating a standardized fleet of reactors based on a repeatable deployment model. Standardization reduces capital costs and improves competitiveness while enabling stronger participation from Polish industry in advanced nuclear projects.”

“This investment represents a major milestone for nuclear energy development in Poland,” said Jason Cooper, CEO of GVH. “Advancing the BWRX-300 design to accelerate deployment demonstrates what can be achieved through shared vision and coordinated investment.”

Rafał Kasprów, CEO of OSGE, added: “The agreement covers the design of nuclear power plants in compliance with Polish regulations and will support the rollout of multiple BWRX-300 units across various locations. This standardized approach is central to our strategy, enabling cost reductions and the development of a strong supply chain, ultimately lowering electricity costs for consumers.”

Global interest in the BWRX-300 continues to grow. The first unit is currently under construction at Ontario Power Generation’s Darlington site in Canada, with completion expected before the end of the decade, making it the first SMR in the Western world. Key components, including the reactor pressure vessel, are already in production, and construction is progressing as planned. In the United States, the U.S. Nuclear Regulatory Commission is reviewing an application from the Tennessee Valley Authority to build a BWRX-300 reactor at the Clinch River site in Oak Ridge, Tennessee. These developments reinforce GVH’s position as a leader in scaling and commercializing SMR technology globally.
