In sum – what to know:
Nuclear-powered pilot – Blykalla, evroc, and Studsvik will explore co-locating SMRs and AI infrastructure at Studsvik’s licensed nuclear site in Nyköping.
Clean baseload energy – The plan leverages SMR technology to supply fossil-free, stable power for hyperscale cloud and AI operations.
Sweden’s leadership push – The initiative could make Sweden a European frontrunner in sustainable, nuclear-powered data center design.
Blykalla, evroc, and Studsvik have signed a deal to develop Sweden’s first nuclear-powered data centers at Studsvik’s licensed nuclear site in Nyköping.
The project brings together Blykalla’s advanced lead-cooled small modular reactor (SMR) technology, evroc’s AI and cloud infrastructure expertise, and Studsvik’s operational nuclear site and lifecycle management capabilities.
Under the terms of the agreement, the companies will evaluate the technical and commercial feasibility of co-locating SMRs and data centers and outline potential power purchase structures for future deployment.
The trio said there is growing opportunity for nuclear-powered data centers, as AI and electrification drive demand for clean baseload energy. SMRs are emerging as a viable solution, offering consistent power supply and operational redundancy for hyperscale AI infrastructure, they added.
They will form a joint steering committee to assess the site and business model, with formal partnership negotiations expected later this year.
Evroc’s founder and CEO, Mattias Åström, said the partnership supports Sweden’s ambition to lead in climate-neutral digital infrastructure.
“Recognizing that the hyperscale AI infrastructure required to ensure Europe’s digital autonomy, demands significant and uninterrupted power, this partnership enables us to effectively explore energy solutions that are both fossil-free and capable of meeting the massive, constant demands of AI-driven infrastructure,” Åström told RCR Wireless News.
The executive also noted that this initiative aligns with the firm’s mission to drive European digital sovereignty. “By leveraging Blykalla’s advanced SMRs to provide clean, reliable, baseload energy and Studsvik’s licensed nuclear site for secure, local deployment, collectively we can lay an important framework to assess feasibility in establishing nuclear-powered data centers.”
When asked if the pilot at Studsvik proves viable, the model of nuclear-powered data centers could be replicated in other European markets, the executive stated that it was too early to discuss replication across other markets as there are so many variables to consider, from regulatory frameworks to energy infrastructure.
“That said, the foundation is being built to explore how this model could scale, with collaboration, innovation, and regional energy solutions at its core. The goal is clear: pave the way for Europe to lead in sustainable, high-performance AI infrastructure,” Åström added.
