Can small nuclear reactors deliver for Europe?

SMR’s promise affordable, low-carbon nuclear power, but the continent will reap the benefits only if governments abandon piecemeal projects and deploy reactors at scale.

Europe needs reliable, low-carbon power for its industries, cities and energy security and it will need even more in the coming decade. Small modular reactors are increasingly seen as part of the solution, but only if the European Union develops them as an industrial program rather than a series of scattered national experiments.

SMRs must be deployed as a fleet. Repetition can reduce costs and build the supply chains Europe needs. The next three years will determine whether Europe develops that capability itself or watches it emerge elsewhere.

The fleet logic

SMRs are often sold on the promise of being cheaper than large reactors. On a first-of-a-kind basis, they are not.

Their economics depend on something different: serial production.

An illustrative model by the EFI Foundation shows why: in a four-unit SMR order book, the fourth unit is around one-sixth cheaper than the first. The savings come from factory fabrication, standardized designs, established supply chains and the learning gained from each successive unit.

This has a policy implication. In the short term, no single European market will be able to anchor a fleet on its own. The order book needed to drive SMRs down their cost curve must be European in scale, otherwise large-scale deployment will remain out of reach.

The European Commission projects between 17 and 53 gigawatts of SMR capacity across the EU by 2050.

The range itself is telling: even the lower bound would require a serious industrial program; the upper bound would put Europe among the leaders in SMR deployment. ……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………https://www.theparliamentmagazine.eu/news/article/oped-can-small-nuclear-reactors-deliver-lowcost-energy-for-europe
