Nyköping – September 07, 2026 -- Studsvik AB, GE Vernova Hitachi Nuclear Energy and Samsung C&T have signed an exclusive agreement to advance a four-unit BWRX-300 nuclear project totaling roughly 1,200 MWe in Sweden, with the first unit targeted for operation in the mid-2030s.
Consortium selects GE Vernova Hitachi and Samsung C&T after competitive review
Following a competitive evaluation process, Studsvik named GE Vernova Hitachi Nuclear Energy as reactor design authority and Samsung C&T as execution partner for the ReFirm programme. GE Vernova Financial Services and Seoul-based DS Investment Partners join as financing partners, with DS Investment Partners leading investment structuring during the exclusivity period.
Project will site at Nyköping's licensed facility or the Målma site in Valdemarsvik
Studsvik operates an existing licensed nuclear facility at Nyköping. At Valdemarsvik, an application was submitted in March 2026 -- the first filed under Sweden's new legislation requiring government approval for nuclear facilities. Which site hosts the initial four-unit project will be determined during development work.
ReFirm programme originated through Kärnfull Next acquisition earlier this year
The ReFirm platform entered the Studsvik Group through its 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.
Consortium divides responsibilities across permitting, design and financing
Studsvik will lead permitting, environmental impact assessment, site rights and dialogue with the Swedish state. GE Vernova Hitachi leads reactor design, licensing support and cost estimation, acting with Samsung C&T as the execution team responsible for design and construction delivery. A joint project company will be established to support development, financing, construction, ownership and operation of the plants, with terms finalized in definitive agreements.
Sweden's 2026 legislation opens nuclear sites beyond three existing plants
Sweden's nuclear expansion is governed by legislation in force since 2026 that permits reactors at new sites and requires government approval for each project, backed by a state financing framework of loans and two-way contracts for difference.
