Denmark starts research on the possible use of nuclear energy.

A framework has been established to explore the "potential and risks" of new nuclear technologies, including small modular reactors (SMRs), as well as to consider lifting the nuclear power moratorium, as announced by Denmark's Ministry of Climate, Energy and Utilities.

In 1985, the Danish parliament resolved that nuclear power plants would not be constructed in the country. However, in a parliamentary vote last May, two-thirds of Danish MPs supported investigating the potential use of nuclear power to strengthen energy security. This analysis aims to facilitate an informed debate on potentially lifting the nuclear power ban.

The ministry highlighted that while the government does not view conventional nuclear power as applicable in Denmark, there has been a growing interest in new nuclear technologies, particularly SMRs, both in Denmark and the EU. This interest arises amidst ongoing SMR developments and a focus on achieving balance in a fossil-free energy system, along with concerns about European energy independence, stable energy prices, consistent electricity supply, and business opportunities.

The ministry has indicated that the groundwork for analyzing new nuclear technologies is established, and initial analysis efforts have commenced.

The analysis will explore whether SMRs could be integrated into Denmark's energy system, evaluating economic costs and benefits; the necessity for new national regulations and authority structures relevant to establishing nuclear plants; and a detailed work plan to address identified needs to ensure the adequate establishment of such plants, including essential political decisions related to lifting the ban. It will also look into commercial interests and the potential for developing and supplying SMR components, as well as larger businesses in Denmark as potential electricity and heat customers.

Furthermore, the analysis will provide an immediate estimate of resource requirements and considerations regarding authority organization and state departmental responsibilities if the ban is lifted and SMRs are developed, tested, and established in Denmark. This will encompass evaluating the need for new full-time positions in state authorities.

The ministry noted that the analysis itself will not directly initiate new efforts toward establishing nuclear technologies in Denmark but may serve as a foundation for discussions on the matter.

Minister for Climate, Energy and Utilities Lars Aagaard stated that while green energy from solar and wind will continue to be the core of Denmark's energy supply, it cannot be the sole solution. He emphasized the need to consider other technologies, such as SMRs, for future green energy. However, he warned that mass-produced SMRs are not a quick solution and highlighted the importance of managing regulatory processes, safety, waste, competencies, and responsibilities thoroughly. The analysis will provide a well-informed basis for political decision-making.

Aagaard expressed his open-minded approach to nuclear power and encouraged a constructive debate on lifting the ban, stressing the importance of thorough deliberation regarding the associated challenges before making any decisions. He emphasized that the potential of SMRs should not be viewed through an ideological lens but rather approached methodically.

The analysis is expected to be finalized by the second quarter of 2026.

In December, several Danish business organizations, universities, and companies formed the Nuclear Power Alliance to advocate for a technology-neutral stance on nuclear energy in Denmark. The alliance includes prominent organizations like the Confederation of Danish Industry, Dansk Metal, and the Novo Nordisk Foundation, along with firms such as chemical engineering company Topsoe and consultancy Niras, alongside 92 Capital, a private equity fund focused on investments in the nuclear energy sector.
