Denmark explores possible use of nuclear power. It is interested in modular reactors

Denmark has long been opposed to nuclear power, as a ban on building such facilities has been in force in the country since the mid-1980s. However, this could change in the future. The government says that while the country is not interested in conventional nuclear power plants, small modular reactors are a different matter. The government will therefore explore the potential use of new nuclear technologies, which could eventually lead to the ban on their use being lifted.

The Danish government’s change of stance comes as no complete surprise: its intention to explore the potential use of new nuclear technologies was announced as early as last May. At the time, Minister for Climate, Energy and Utilities Lars Aagaard announced that the government would conduct a thorough analysis of new nuclear technologies, particularly their potential to complement renewable energy sources and improve the stability of electricity supplies.

According to the World Nuclear News website, the ministry said at the end of January that the framework for analysing new nuclear technologies was ready and that initial work had begun. The aim of the analysis is to determine whether small modular reactors (SMRs) could be integrated into the Danish energy system, including an assessment of their economic costs and benefits.

“Although the government does not consider conventional nuclear power relevant in Denmark, interest in new nuclear technologies such as small modular reactors has grown in Denmark and the EU in recent years. This needs to be viewed, among other things, in light of the continued development of modular reactor technologies, a greater focus on balancing the energy system without fossil fuels, the increased emphasis on Europe’s energy independence, stable and low energy prices, reliable electricity supplies, and growing interest from businesses,” the Danish ministry said, according to the website.

The analysis is also intended to clarify the need for new national regulations, the structure of authorities, and the responsibilities relevant to the possible construction of nuclear power plants in the country. It will also examine commercial interests and the potential for developing technologies and supplying components for modular reactors. Finally, the analysis is expected to identify potential customers for electricity or heat from nuclear sources. It should be available in the second quarter of this year.

“The analysis itself will not lead to the launch of new initiatives to develop new nuclear technologies in Denmark, but it could provide a basis for discussion on the subject,” the ministry added.

According to Minister Aagaard, green energy from the sun and wind now forms the backbone of Denmark’s energy system, and will continue to do so. However, he said, the government recognises that the energy system cannot operate on this basis alone.

“That is why we need to be open to the possibility that other technologies could also provide us with green energy in the future. Small modular nuclear reactors could be one option. However, mass-produced SMRs are neither a quick fix nor a free pass, and we need a basis for gaining control over regulatory processes, safety, waste, expertise, and responsibility. This analysis will give us a solid, informed foundation on which to make policy decisions,” Minister Aagaard said.
