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.

The agreement marks the next phase of development and does not constitute a final investment decision or authorisation to construct. The parties will begin joint development work immediately, including commercial, technical, regulatory and financing activities during the exclusivity period.

Studsvik leads permitting, the environmental impact assessment, site rights, community engagement and the dialogue with the Swedish state. GE Vernova Hitachi leads reactor design, licensing support and cost estimation and acts as design authority, and, together with Samsung C&T, acts as the execution team, giving the project single-point responsibility for design and construction delivery. During the exclusivity period, DS Investment Partners, a South Korean investment firm, will lead the investment and GE Vernova Financial Services participates in an advisory and financial structuring capacity in support of the consortium.

A joint project company will be established to support development, financing, construction, ownership and operation of the plants, with details to be finalised in definitive agreements.

Sweden is expanding nuclear capacity under legislation in force since 2026 that permits reactors at sites beyond the three existing plants and requires government approval for each, supported by a state financing framework of loans and two-way contracts for difference.

“Sweden’s electricity supply is a long-term play: existing nuclear capacity is ageing, and demand for baseload power is growing. To meet that, we have looked for long-term partners and for the conditions that let projects like this succeed. In GE Vernova Hitachi and Samsung C&T we have found them. We intend to build the first project either on an existing nuclear site or on greenfield. One reactor is a project. Four is the start of an industry.”

– Karl Thedéen, President and Chief Executive Officer, Studsvik

“Today’s announcement is about helping Sweden turn its energy ambitions into reality in a timeframe that matters for its communities and industries. The country has a strong foundation of nuclear expertise and operational excellence, and the BWRX-300 combines proven boiling water reactor technology with the lessons being learned every day at the Darlington New Nuclear Project in Canada. Together with a growing global pipeline of projects across North America and Europe, this experience gives Sweden access to a technology that is moving from first-of-a-kind deployment toward fleet-scale execution.”

– Jason Cooper, Chief Executive Officer, GE Vernova Hitachi Nuclear Energy

“Samsung C&T is honoured to partner with Studsvik, GE Vernova Hitachi and the other members of the development team to support Sweden’s next generation of nuclear energy. By combining proven technology, world-class EPC execution, operational excellence and financing capability, we are establishing a strong foundation for the successful development of the ReFirm programme. We are equally committed to strengthening Sweden’s industrial capability, expanding local supply chains and building a long-term strategic partnership that creates lasting value for Studsvik and Sweden.”

– Oh Se-chul, President and Chief Executive Officer, Engineering & Construction Group, Samsung C&T

Today’s announcement is not expected to have any material financial impact on the Studsvik Group’s earnings for 2026.
