Sweden Takes Major Step Forward in Nuclear Energy with Small Modular Reactors

Sweden announces investment in Small Modular Reactors as part of its nuclear energy strategy.

    Key details

  • • Vattenfall invests in SMRs at Ringhals, utilizing technology from GE Vernova or Rolls-Royce.
  • • Three to five SMRs will produce about 1,500 MW of energy, equivalent to existing largest reactors.
  • • Prime Minister Kristersson emphasizes the need for political stability in executing long-term nuclear plans.
  • • Industry leaders call for swift project commencement to meet rising electricity demands.

In a landmark development for Sweden's energy strategy, Vattenfall has officially committed to investing in small modular reactors (SMRs) for the first time in over 50 years. Announced on August 21, 2025, this initiative aims to modernize Sweden's nuclear energy capabilities amidst rising electricity demand and an urgent need for sustainable energy solutions.

Vattenfall, Sweden's state-owned energy company, has selected either GE Vernova or Rolls-Royce as its technology partners to build new reactors at the Ringhals nuclear power plant. Plans include acquiring 3 to 5 SMRs that will collectively provide around 1,500 megawatts (MW) of capacity, matching that of the country’s largest existing reactors. This investment aligns with the broader national energy policy to enhance nuclear power generation, ensuring stability and reducing reliance on fossil fuels.

During the announcement, Prime Minister Ulf Kristersson underscored the significance of this decision, stating it marks a pivotal shift in Sweden's energy landscape as it moves towards modern nuclear solutions. He noted that the long-term nature of nuclear projects requires sustained political stability to navigate through various phases of implementation. Notably, this initiative may encourage a broader political consensus on nuclear energy, a topic that sparked heated discussions during the recent elections.

Industry leaders have welcomed the decision. Pia Sandvik, CEO of Teknikföretagen, expressed the urgent need to begin such projects to meet escalating energy demands efficiently. The shift to SMR technology, characterized by lower costs, shorter construction times, and reduced safety zones, is anticipated to be more appealing to political factions previously skeptical about nuclear energy, such as the Social Democrats and the Center Party.

As Europe sees similar ventures with countries like the UK, France, and Estonia advancing their SMR plans, Sweden aims to capitalize on this trend. The development of new nuclear infrastructure is regarded as essential, especially with aging energy production facilities nearing their operational limits. Vattenfall's initiative is framed not only as a response to current needs but as a strategic move towards sustainable economic growth and energy independence for Sweden in the years ahead.

In summary, Sweden's foray into SMR technology represents a committed step towards revitalizing its nuclear energy strategy, amidst growing demands and the imperative of sustainable energy solutions, paving the way for enhanced capacity and reduced carbon emissions.
