In most manufacturing sectors, costs drop as production increases due to economies of scale and learning by doing. However, the nuclear industry often experiences negative learning, where costs remain high or even increase over time. This phenomenon is driven by several unique structural factors.
First, the complexity and extreme safety requirements of nuclear projects necessitate highly specialized labor and incredibly rigorous quality control. As regulations evolve and safety standards become even more stringent, the complexity of construction increases. Second, the bespoke nature of many nuclear plants means that each project is treated as a unique engineering feat rather than a standardized product. This prevents the repetitive manufacturing efficiencies seen in industries like solar or wind.
Third, the long timelines required for construction create massive financial risks. High interest rates and capital costs over decades can outweigh any potential savings from increased experience. Additionally, supply chain fragmentation makes it difficult to maintain a steady workforce and specialized component production. Instead of becoming cheaper through repetition, the rising costs of regulatory compliance and project delays often create a cycle of increasing capital intensity.
