Germany: Ministry of the Environment: Mini‑reactors [SMNRs] not an option

Berlin (energate) – The gap between the hype and industrial reality surrounding nuclear energy is widening. This applies in particular to the smaller nuclear reactors, Small Modular Reactors (SMR). This is the conclusion of the World Nuclear Industry Status Report, which was commissioned by the Heinrich Böll Foundation, the Federal Office for the Safety of Nuclear Waste Management (BASE) and the Friedrich Ebert Foundation, among others.

According to the study, nuclear energy remains “irrelevant” on the global market, as the 5.4 
GW increase in nuclear capacity is offset by 100 times the combined new capacity of over 565 
GW of wind and solar energy. Wind and solar plants
 worldwide currently generate 70 per cent more electricity than nuclear reactors.

According to the report, there is still no market-ready product for Small Module Reactors (SMR), only a design certification and an approved standard design. Both come from the US company NuScale. The US Nuclear Regulatory Commission has already approved a total of three of the company’s models, but previous contracts with potential customers have been cancelled due to increased costs.
 A first mini-reactor was cancelled in 2023.

The Netherlands and France continue to rely on nuclear power

Despite these failures, other countries are sticking with nuclear energy. In the Netherlands, a debate on the use of SMR, which is seen as a measure to achieve the 2030 climate targets, has been ongoing for several years. In addition, the Dutch company Mammoet signed a memorandum of understanding with Electricité de France (EDF) at the end of 2025, which provides for the construction of nuclear plants in the Netherlands. Two nuclear power plants were already planned for 2022 and two more are still in operation.

Debate continues in Germany

Although Germany has withdrawn from nuclear energy, the debate about its benefits continues. Parliamentary State Secretary Rita Schwarzelühr-Sutter also spoke at the presentation of the World Nuclear Industry Status Report. When asked by energate, a spokesperson for the Federal Ministry for the Environment explained that Germany had “good reasons” for withdrawing from the use of nuclear power. The risks of nuclear energy and also of the use of SMRs remain “ultimately unmanageable”. In addition, the development and construction of smaller reactors raises many other unresolved issues.

There is also no reliable evidence to date for the safety promises. As a result, the disadvantages of nuclear energy would be transferred from a few large plants to many small ones. Ultimately, “the individual plants may become smaller, but the problems as a whole tend to become bigger”.

 The spokesperson also referred to a study by the Federal Office for the Safety of Nuclear Waste Management, which energate has already reported on. According to the report, the advantages of mass production of SMRs would only outweigh their fundamental cost disadvantages compared to large reactors with a production volume of around 3,000 units.

The CDU/CSU (Christian Democrats) parliamentary group takes a different view. At the end of 2024, the CDU and CSU published a position paper in which they advocated research and development of nuclear power plants, including SMRs. CSUChairman Markus Söder also spoke out in favour of the use of SMRs in an interview with Die Welt at the end of 2025.

A total of 127 different designs worldwide

The report states that it is above all the continuous financial and political support for SMRs that keeps faith in them alive. In particular, private capital injections are playing an increasingly important role in driving research and development forward. There are 127 different SMR designs, so the funding amounts are widely spread. This means that most designs do not have sufficient financial resources to drive development forward

. According to the report, even the US start-up NuScale is still years away from building the first Small Module Reactor, although several designs have already been approved.
