The article argues that small modular nuclear reactors (SMRs), despite growing interest from governments, tech companies, and some environmental advocates, are unlikely to solve the core problems of nuclear energy or the global energy crisis.

It begins by describing the renewed enthusiasm for nuclear power driven by climate goals, rising electricity demand from artificial intelligence data centers, and geopolitical energy disruptions.

SMRs are promoted as cheaper, safer, and faster to build than conventional nuclear plants, with backing from major investors and political support in several countries.However, the author contends that these claims are largely unproven.

Historically, nuclear power has faced persistent issues including extremely high construction costs, long build times, unresolved radioactive waste storage, uranium resource constraints, safety risks, and vulnerability to water scarcity and climate-related disasters.The article argues that SMRs do not fundamentally resolve these issues.

While proponents claim SMRs could reduce costs through factory-based modular construction and improve safety via passive cooling systems, the author notes that no large-scale real-world deployment data exists to confirm these benefits.

The article also critiques proposed advanced nuclear technologies such as fast breeder reactors, thorium reactors, and alternative cooling systems, suggesting they introduce new technical, economic, and safety challenges without solving core limitations.Uranium supply constraints and low energy return from alternative extraction methods, such as uranium from seawater, are also highlighted.Ultimately, the author concludes that SMRs are part of a broader attempt to preserve industrial energy systems rather than a genuine solution.

They argue that the future energy transition should prioritize low-tech, decentralized, and nature-based solutions, as well as reduced overall energy consumption.In this view, SMRs are seen as expensive, slow to deploy, and incompatible with the urgency of current energy and climate challenges.
