With a few SMR projects built and operational at this point, and more plants under development, the Institute for Energy Economics and Financial Analysis (IEEFA) concludes in a report that SMRs are “still too expensive, too slow to build, and too risky to play a significant role in transitioning away from fossil fuels.”
Be that as it may, nuclear is not the answer either.
I wouldn’t go that far, but it’s fair to say that small nuclear is unproven, both in terms of operational reliability and safety, and also in terms of its economic viability. The economic viability of large nuclear generation plants is also questionable, once you remove all the explicit and implicit subsidies that have kept the industry alive since its start.
It’s a more competitive if you remove the fossil fuel subsidies.
