USA, / Poland: GE Vernova Hitachi Nuclear Energy and Orlen Synthos Green Energy have signed an agreement to advance the Polish generic design of the BWRX-300 small modular reactor (SMR), marking a key step toward deployment in Poland.
The Poland Generic Design Agreement was signed in Washington, D.C., and will see OSGE invest in developing a detailed reference design for future BWRX-300 projects in Poland. The design will be aligned with Polish regulatory requirements and intended for use across multiple sites.
Polish officials said the move supports the country’s energy transition by progressing both large-scale nuclear power plants and SMR technology in parallel. SMRs are expected to provide stable, zero-emission baseload electricity for energy-intensive industries, help stabilise prices for end users, and strengthen Poland’s nuclear supply chain.
The generic design is intended to underpin a standardised, repeatable deployment model. According to the partners, this approach can reduce unit capital costs, improve competitiveness and increase opportunities for Polish companies to participate in advanced nuclear projects.
GVH said the agreement reflects growing global momentum behind the BWRX-300. The first unit is currently under construction at Ontario Power Generation’s Darlington site in Canada and is expected to be completed by the end of the decade. In the United States, the Nuclear Regulatory Commission has accepted and is reviewing an application from the Tennessee Valley Authority to build a BWRX-300 at the Clinch River site in Tennessee.
The partners said advancing the Polish generic design will help accelerate SMR deployment, support long-term energy security and contribute to the development of a low-carbon power system as electricity demand continues to rise.
