ABB and Swedish nuclear energy company Blykalla have signed a Memorandum of Understanding to develop advanced nuclear reactor technology, with the aim of supporting Sweden’s efforts to produce clean and reliable baseload energy. The collaboration will initially concentrate on constructing an electrical small modular reactor (SMR) pilot facility near the coastal town of Oskarshamn, approximately 340 km south of Stockholm, to test proof of concept before expanding to future plants.
Within the scope of the MoU, ABB will explore how its automation, electrification and digitalisation solutions can support Blykalla’s SMR prototype SEALER-E, which features a lead-cooled reactor. This includes cyber security frameworks to ensure compliance with nuclear safety regulations.
The intention is to use ABB’s experience of power distribution, control and automation technologies and system integration as the groundwork for a successful deployment of advanced nuclear technologies as part of the collaboration.
Jacob Stedman, CEO of Blykalla: “We see strong momentum in Sweden for nuclear power in general, and SMRs in particular. This is why we look forward to bringing our technology to market as part of efforts to enable the transition to a net zero future.”
Nuclear reactors currently provide about 30 % of Sweden’s electricity. In November 2023, its government unveiled a roadmap to the expansion of nuclear energy, increasing the country’s capacity by the equivalent of two large-scale reactors (2500 MW) by 2035 and building up to 10 000 MW by 2045, which could include SMRs. This supports the goal of a completely fossil-free electricity system.
According to the International Energy Agency, nuclear power plays an important role in helping the energy sector move away from fossil fuels faster and in a more secure way. SMRs are believed to offer lower capital costs and enhanced safety and flexibility in deployment in comparison with conventional nuclear power plants. They could also reuse the sites of retired fossil fuel power plants, taking advantage of existing transmission, cooling water and skilled workforces.
Blykalla is developing and building small modular reactors to deliver the next generation of clean energy. The SEALER reactor utilises liquid lead cooling and features what are said to be unique safety elements and proprietary innovations. The company aims to provide necessary baseload energy to enable a complete transition to a fossil-free future and is actively collaborating with global partners to deliver Sweden’s next nuclear reactor within this decade.
