NYKÖPING, Sweden, Sept. 3, 2026
Following a competitive evaluation process, Studsvik has selected GE Vernova Hitachi Nuclear Energy and Samsung C&T as its strategic partners for the first project to build new nuclear power, either at its existing licensed nuclear site in or at the Målma site in Valdemarsvik.
Together with GE Vernova Financial Services and DS Investment Partners, the companies will advance an initial four-unit BWRX-300 project in Sweden, totalling 1.2 GW of new nuclear generating capacity, with the first unit expected in operation in the mid-2030s.
/PRNewswire/ — Studsvik AB (publ), GE Vernova Hitachi Nuclear Energy, GE Vernova Financial Services, DS Investment Partners and Samsung C&T today announced an agreement to advance the ReFirm nuclear programme at Studsvik’s sites in Sweden. The agreement is exclusive for a fixed period, which the parties may extend.
ReFirm is a multi-site small modular reactor (SMR) and new nuclear development program that became part of the Studsvik Group through the acquisition of Kärnfull Next (KNXT) earlier this year. KNXT has worked with GE Vernova Hitachi on BWRX-300 deployment in Sweden since 2022 and entered a strategic teaming agreement with Samsung C&T in December 2024. Today’s announcement covers sites at Nyköping and Valdemarsvik and provides for development to commence with a four-unit BWRX-300 project of approximately 1,200 MWe in total at one of them.
At Nyköping, Studsvik operates an existing licensed nuclear facility. At Valdemarsvik, an application was submitted in March 2026, the first made under Sweden’s new legislation requiring government approval for nuclear facilities. Which site hosts the first project will be decided during the development work.
The phased, multi-unit structure is intended to support standardisation across the programme and creates opportunities to capture lessons learned from early deployment and apply them to subsequent units, helping improve cost, schedule and productivity outcomes.
It will also help maximise Swedish industrial participation throughout engineering, procurement, construction, and long-term operations. This reflects the broader objective of building a supply chain that can support not only the first project, but also follow-on units and wider deployment opportunities in Sweden and Europe.
Studsvik has worked in nuclear technology for more than 75 years, and that capability is what a new plant needs to get through design, qualification and commissioning. Beyond any equity participation, a domestic new-build programme of this scale is expected to create long-term opportunities for Studsvik’s services over the operating life of the plants.
