These 3 companies have teamed up to explore development of Sweden’s first nuclear-powered AI data centres

Blykalla, evroc, and Studsvik have signed a Memorandum of Understanding (MoU) to explore the development of Sweden’s first nuclear-powered data centres.

Blykalla, evroc, and Studsvik have signed a Memorandum of Understanding (MoU) to explore the development of Sweden’s first nuclear-powered data centres at Studsvik’s licensed nuclear site in Nyköping.

The partnership combines expertise in advanced nuclear technology, hyperscale cloud infrastructure, and licensed nuclear operations to accelerate the deployment of climate-neutral, high-performance computing powered by small modular reactors (SMRs).

The goal is to assess the commercial and technical viability of co-locating data centres and SMRs at the Studsvik licensed site.

This includes speaking with local municipalities and landowners and outlining a possible plan for future power purchase agreements.

The parties will form a joint steering committee to review the site and business model, with the aim of starting formal partnership talks later this year.

This collaboration is intended to provide clean and secure power for Europe’s AI and digital infrastructure.

Blykalla: Developer of advanced SMRs

Blykalla is a Swedish company that develops advanced small modular reactors (SMRs), specifically lead-cooled fast reactors for industrial use.

Their SEALER technology is a compact 55 MWe unit designed for safety, efficiency, and scalability.

The OECD Nuclear Energy Agency’s annual report shows that Blykalla has the most advanced reactor concept in Europe.

With strong support from partners like Oklo, Uniper, and ABB, Blykalla is set to deliver Europe’s first advanced SMR, providing reliable and sustainable energy for AI and clean industries.

“This collaboration is an opportunity for Sweden to be a leader in digital infrastructure. lt allows us to demonstrate how SMRs can provide the stable, fossil-free energy that is required for the AI revolution,” says Jacob Stedman, CEO of Blykalla. “Studsvik’s site and evroc’s ambitions offer the right conditions for a groundbreaking project.”

evroc: building Europe’s hyperscale cloud and AI infrastructure

Based out of Stockholm, evroc is building Europe’s hyperscale cloud and AI infrastructure.

With development offices in France and the UK, the company plans to operate 10 hyperscale data centres by 2030, creating thousands of jobs in Europe.

“The ever-growing demand for AI underscores the urgent need to rapidly deploy massive hypserscale AI infrastructure. Through our collaboration with Blykalla and Studsvik, we are exploring a model where Sweden can lead in building climate-neutral digital infrastructure,” comments Mattias Åström, Founder and CEO of evroc.

Studsvik: Advanced technical services

Studsvik offers advanced technical services for the global nuclear power industry.

Their main focus areas include fuel and materials technology, reactor analysis software, decontamination, radiation protection, and solutions for managing radioactive waste.

With more than 75 years of experience, Studsvik is a reliable partner in nuclear technology and radiological services.

“Studsvik’s provides a unique platform of site infrastructure and unique competence to combine advanced nuclear with next-generation industry. This MoU is an important step in evaluating how such synergies can be realised in Sweden,” comments Karl Thedéen, CEO, Studsvik.
