# Source note — Studsvik / GE Vernova Hitachi / Samsung C&T BWRX-300 Sweden consortium (2026-09-04)

## Selected source-card
**Article:** `blog/articles/studsvik-bwrx300-sweden-smr-consortium-source-card.html`  
**Evidence label:** official company releases plus trade/wire reporting. This is a development agreement and project-advancement signal, not a final investment decision, construction authorization, reactor licence, or operating power plant.

## Why selected
- New substantive September 3, 2026 SMR development not already covered as its own Managing Expectations Energy article.
- Strong source stack: Studsvik official release, GE Vernova release, PR Newswire distribution and World Nuclear News trade reporting.
- Directly relevant to SMR standardization, BWRX-300 deployment, international nuclear financing, firm power, data-center/industrial-load planning, and uranium/fuel-chain watch readers.

## Facts safely used
- Studsvik announced it selected GE Vernova Hitachi Nuclear Energy and Samsung C&T as strategic partners for the ReFirm programme.
- The parties plan to advance an initial four-unit BWRX-300 project in Sweden, totalling about 1.2 GW / 1,200 MWe.
- The first unit is expected in the mid-2030s, according to the company releases.
- Candidate sites are Nyköping, where Studsvik operates an existing licensed nuclear facility, and Valdemarsvik/Målma, where an application was submitted in March 2026 under new Swedish legislation.
- The release says the agreement is exclusive for a fixed period and that joint development work starts immediately across commercial, technical, regulatory and financing tracks.
- The release also states the agreement does not constitute a final investment decision or authorization to construct.

## Cautions / fairness
- Do not frame this as Sweden approving, financing or building four reactors. The project still needs definitive agreements, site selection, environmental/permitting work, state support/financing, regulator and government decisions, supply-chain execution and an FID.
- Company and partner releases are strong for what the parties announced, but not independent proof that costs, schedules, grid interconnection, public consent, fuel supply, waste handling or financing terms will hold.
- Swedish government financing-framework material is context only unless the specific project receives support under that framework.
- Not investment advice: references to Studsvik, GE Vernova, Samsung C&T, DS Investment Partners, BWRX-300, uranium/fuel demand and nuclear supply chains are public-interest infrastructure context only.
