## Is Samsung C&T Now a Key Player in European SMR Construction?

Samsung C&T has signed a joint development agreement (JDA) with [GE Vernova / GE Hitachi Nuclear Energy](https://smrintel.com/companies/ge-vernova) (GEH) and Swedish nuclear company Studsvik AB to jointly develop a 1.2 GW SMR project in Sweden — four units of the BWRX-300 at 300 MWe each. The agreement was signed in Stockholm on September 3, 2026. Samsung C&T and GEH were selected as EPC partners following a competitive process among three consortiums that began in May 2025. The project targets commercial operations in the mid-2030s, on a Studsvik-owned site already licensed for nuclear facility operation.

This is a significant commercial milestone for both GEH's BWRX-300 program and for Korean construction conglomerates seeking to establish a European nuclear EPC foothold. The BWRX-300, a [boiling water reactor](https://smrintel.com/glossary/bwr) derivative, is currently under construction at Darlington, Ontario — a project that completed its operating licence application in April of this year, making Darlington the reference [first-of-a-kind (FOAK)](https://smrintel.com/glossary/foak) unit. The Sweden deal represents one of the largest European SMR project commitments announced to date.

## What Is the Sweden BWRX-300 Project?

The project is structured around four BWRX-300 units, each rated at 300 MWe, for a combined capacity of 1.2 GW. The reactor design is developed by GEH and is based on proven boiling water reactor (BWR) technology — generating electricity by using steam produced directly in the reactor core to drive a turbine.

Studsvik AB, the project organizer, is not a newcomer. Founded in 1947 as a central institution of Sweden's national nuclear program, the company operates across more than 20 countries and manages capabilities spanning new plant development, operational support, and decommissioning. Its ownership of a site with existing nuclear facility licensing is a non-trivial advantage — greenfield nuclear site licensing in Europe is a multi-year, high-friction process, and a pre-licensed site materially de-risks the development schedule.

Under the JDA structure, Studsvik retains responsibility for overall business development: licensing, environmental impact assessment, and government consultation. Samsung C&T and GEH function as joint EPC partners, engaged from the initial project development phase through to construction.

## How Samsung C&T Was Selected — and What It Signals

The selection followed a competitive process between three consortiums that launched in May 2025. That Samsung C&T and GEH emerged as the final partners — over presumably European and other international competitors — reflects two things: GEH's confidence in the BWRX-300's commercial traction with a proven EPC partner, and Samsung C&T's push to translate its South Korean nuclear construction experience into a repeatable European SMR offering.

Samsung C&T's stated strategic intent is explicit: it views the Sweden project as a "bridgehead for entering the European SMR market," according to a company official quoted in the announcement. That framing matters commercially. Europe's nuclear pipeline is expanding rapidly, and an EPC contractor with a completed European SMR reference project will have significant advantages in subsequent bid competitions in Poland, the Czech Republic, the Netherlands, and elsewhere.

This is worth scrutinizing carefully, however. A JDA is an early-stage agreement — it governs joint development activities, not yet a full EPC contract. The path from JDA to construction permit to first concrete involves licensing timelines, financing arrangements, and Swedish regulatory approvals that are not yet resolved. The mid-2030s commercial operations target is credible for a BWRX-300 unit with a pre-licensed site and a mature reference project at Darlington, but it assumes regulatory progression in Sweden proceeds without significant delays.

## Sweden's Nuclear Roadmap Creates Real Demand

The macro context supports the project's viability. The Swedish government is pursuing a roadmap to secure 2.5 GW of new nuclear capacity — including both SMRs and large reactors — by 2035, scaling to 10 GW by 2045. That policy trajectory, driven by energy security concerns and carbon neutrality commitments, provides regulatory and political tailwinds that were absent from Swedish nuclear policy just a few years ago.

Four BWRX-300 units contributing 1.2 GW would represent nearly half of the 2035 interim target, making this project central — not peripheral — to Sweden's stated nuclear ambitions. For the broader European SMR market, a successful Studsvik/Samsung C&T/GEH project would establish a Western SMR construction reference in an EU member state with rigorous regulatory standards, which would accelerate procurement decisions elsewhere on the continent.

## Implications for the BWRX-300 Program

The BWRX-300 is accumulating commercial commitments across multiple jurisdictions. Darlington provides the FOAK construction reference; the Sweden project, if it progresses to construction, would add a second operating geography and help drive NOAK cost reductions through supply chain repetition and design standardization. For GEH, landing a 1.2 GW order in Europe alongside the Canadian flagship project strengthens the case that the BWRX-300 has genuine multi-market commercial momentum — not just a single government-supported demonstration.

The EPC partnership structure with Samsung C&T also diversifies GEH's construction execution risk. Samsung C&T brings substantial large-project construction capacity, and its involvement distributes some of the schedule and cost risk that has historically challenged FOAK nuclear builds.

## Key Takeaways

- **Samsung C&T and GEH signed a JDA** with Sweden's Studsvik AB on September 3, 2026 to jointly develop a 1.2 GW BWRX-300 SMR project — four units at 300 MWe each.
- **The project site is already licensed** for nuclear facility operation, reducing a key development risk relative to greenfield alternatives.
- **Samsung C&T and GEH were selected** after competing against two other consortiums in a process that began May 2025.
- **Commercial operations target is mid-2030s**, consistent with the BWRX-300's Darlington reference project timeline.
- **Sweden's national roadmap** calls for 2.5 GW of new nuclear capacity by 2035 and 10 GW by 2045 — this project addresses roughly half the near-term target.
- **A JDA is not yet a full EPC contract** — licensing, financing, and regulatory approvals remain ahead before construction can begin.
- **For GEH**, this is a second major geography for BWRX-300 commercial deployment alongside Darlington, strengthening the NOAK cost reduction case.

## Frequently Asked Questions

**What is the Samsung C&T and Studsvik SMR project in Sweden?**
Samsung C&T, GE Hitachi Nuclear Energy, and Studsvik AB signed a joint development agreement on September 3, 2026 to develop a 1.2 GW SMR project in Sweden using four BWRX-300 boiling water reactors rated at 300 MWe each, with commercial operations targeted for the mid-2030s.

**What is the BWRX-300 reactor and where else is it being built?**
The BWRX-300 is a 300 MWe boiling water reactor developed by GE Hitachi Nuclear Energy. Its first commercial deployment is at Darlington, Ontario, Canada, where the operating licence application was completed in April 2026. The Sweden project would be its first European deployment.

**Who is Studsvik AB?**
Studsvik AB is a Swedish nuclear technology company founded in 1947 as part of Sweden's national nuclear program. It operates in more than 20 countries and covers the full nuclear lifecycle from new plant development to decommissioning. It owns the proposed project site, which already holds nuclear facility operating authorization.

**What is Sweden's nuclear energy policy target?**
The Swedish government is pursuing 2.5 GW of new nuclear capacity by 2035, encompassing both SMRs and large reactors, with a longer-term goal of reaching 10 GW by 2045 — driven by energy security and carbon neutrality objectives.

**What does a joint development agreement mean for project progress?**
A JDA establishes the framework for collaborative development activities — licensing work, engineering studies, environmental assessments — but it is not a construction or EPC contract. Full project execution requires subsequent agreements, regulatory approvals, and financing arrangements before construction can begin.
