Are Small Modular Reactors Overrated? Climate Activists Weigh In

The European nuclear industry is making a strong case for small modular reactors (SMRs) as a solution to the continent’s energy and climate challenges. However, many environmental activists remain skeptical.

A report from Climate Action Network Europe, to be released soon, argues that the journey to develop SMRs will likely mirror the difficulties faced by traditional nuclear plants. They foresee potential delays and cost overruns and warn that nuclear waste remains an unresolved issue.

Another concern is the rising power prices. As Europe rapidly expands its renewable energy sources, new nuclear facilities—whether large or small—might have to operate at lower capacities to accommodate cheaper green energy. This could lead to longer payback periods, making electricity from these plants more expensive.

### Concerns About Subsidies

The report raises alarms about using public funds to support high-priced nuclear energy through contracts-for-difference (CfDs). These contracts are designed to stabilize income for energy producers by guaranteeing minimum prices. If the market price drops, the state covers the difference. However, if energy prices rise, taxpayers may end up financing pricier nuclear power instead.

The report stresses that every euro spent on nuclear energy could be better invested in more viable options like renewable energy, energy storage, and efficiency measures.

### A Call for Evidence

CAN Europe urges that no public money should be invested in SMRs until they prove they can generate electricity reliably. They also suggest that developers should bear the costs associated with waste management and accidents instead of passing these charges onto taxpayers.

Interestingly, the report does not explore how SMRs could function in a dedicated manner, supplying energy to specific industries like data centers or hydrogen production, rather than competing directly in the broader energy market.

### Expert Insights

Thomas Lewis, energy policy coordinator at CAN Europe, argues that investing in SMRs could be detrimental. He believes that misallocating funds could hinder Europe’s transition to cleaner energy, keeping emissions and energy costs high.

### Broader Impact

According to a survey from the International Energy Agency, over 80% of new energy investments globally are now directed toward renewables. This shift signifies a changing landscape in energy production and consumer preferences, with a growing demand for cleaner and more sustainable solutions.

The debate over SMRs brings up critical questions about the future of energy in Europe. While nuclear power has its advocates, the emphasis on renewable energy cannot be underestimated. As the market evolves, so will the strategies to meet Europe’s energy needs effectively.

In summary, while SMRs may hold promise, the path to realizing their benefits is fraught with challenges that need to be carefully assessed.
