Blykalla and ABB Enter Joint Development Agreement to Accelerate Development of Blykalla’s Reactors

Stockholm, Sweden

Blykalla and ABB have today signed a Joint Development Agreement (JDA) – marking a significant step forward in their collaboration and formally advancing their partnership.

Blykalla and ABB have been in partnership since October 2024 under a Memorandum of Understanding. With the Joint Development Agreement now in place, the cooperation enters a new phase characterized by structured project plans, a joint Steering Committee, and formalized ownership principles for developed technologies.

Under the JDA, the parties will jointly develop key elements of the electrical prototype reactor, while establishing the framework for collaboration on the demonstration reactor as well as commercial units. The agreement moves the cooperation from exploratory alignment into structured joint development, with clearly defined project frameworks, governance, and intellectual property allocation. It also creates a robust framework for joint R&D activities and establishes a clear path toward deeper technical and commercial integration.

"ABB has been an important partner from early on, and this JDA marks the natural next step in a partnership that keeps deepening, says Jacob Stedman, CEO of Blykalla. "

Furthermore, the agreement establishes ABB as a key partner for automation, control systems, and control room equipment within the defined scope, subject to separate supply agreements. This strengthens the industrial foundation around SEALER and reinforces the ambition to combine Blykalla’s reactor technology with ABB’s expertise in automation and electrical systems.

"Early involvement from our engineers and nuclear specialists gives us the opportunity to be involved in co-creating the next generation. It demonstrates the power of a strategic partnership working at its best. Nuclear provides consistent baseload power generation that can support a stable energy grid. As demand for electricity continues to increase, nuclear power offers a reliable, low-carbon solution as part of the future energy mix", says Daniela Bok, Local Division Manager, ABB's Energy Industries division in Sweden."

The Joint Development Agreement provides the contractual structure needed to advance safe, sustainable and cost-effective nuclear solutions at plant scale, and signals a shared long-term commitment to bringing next-generation nuclear technology to market.
