Studsvik, GE Vernova, Hitachi Nuclear Energy, Samsung C&T, and investment firms have agreed to develop Studsvik's ReFirm nuclear program in Sweden, including plans for four small modular reactors with a combined capacity of about 1,200 megawatts, GE Vernova said in a statement on Thursday.
The partners plan to establish a company to develop, finance, build, own and operate the reactors. They will initially focus on two possible sites, at Nykoping and Valdemarsvik, with the location of the first project to be decided during development.
The project would use four BWRX-300 reactors designed by GE Vernova Hitachi.
Studsvik operates a licensed nuclear facility at Nykoping. At Valdemarsvik, an application to develop a nuclear facility was submitted in March 2026 under Sweden's new rules requiring government approval for new nuclear projects.
The companies said that developing several reactors as part of a single program could improve efficiency by allowing lessons from earlier units to be applied to later ones.
The agreement does not represent a final investment decision or approval to begin construction, the statement said. The partners will now work on technical, commercial, regulatory and financing issues.
Studsvik is to lead permitting, environmental assessments, site rights and government and community engagement. GE Vernova Hitachi is charged with overseeing reactor engineering, licensing support and cost estimates and working with Samsung C&T on project execution.
South Korean investment firm DS Investment Partners will lead investment activities, while GE Vernova's Financial Services business will advise on financing.
