A claim often made by opponents of nuclear energy is that it takes too long to build nuclear power stations. How quickly can we build them, and
how does the speed of building nuclear compare with how fast we can build wind and solar?
The second question is addressed in How fast can we build clean energy?
How long does it take to build a nuclear power plant?
In a blog article[1], Euan Mearns examines data for 441 reactors, finding that
- 374 out of 441 reactors were built in 10 or less than 10 years. There is a tail of 15% that have taken longer to build.
- 18 reactors were completed in 3 years! 12 of those in Japan, 3 in the USA, 2 in Russia and 1 in Switzerland. These are a mixture of boiling water and pressurised water reactors.
- The mean construction time of 441 reactors in use today was 7.5 years.
A peer-reveiwed (but paywalled) statistical analysis of the construction duration of nuclear power plants, by Paul W.Thurner et al[2], finds that "time of connection to grid increases over the years indicating increased societal sensibilities, respect for higher security standards, and increased project complexities".

- The existing literature on the construction costs of nuclear power reactors has focused almost exclusively on trends in construction costs in only two countries, the United States and France, and during two decades, the 1970s and 1980s. These analyses, Koomey and Hultman (2007); Grubler (2010), and Escobar-Rangel and Lévêque (2015), study only 26% of reactors built globally between 1960 and 2010, providing an incomplete picture of the economic evolution of nuclear power construction. This study curates historical reactor-specific overnight construction cost (OCC) data that broaden the scope of study substantially, covering the full cost history for 349 reactors in the US, France, Canada, West Germany, Japan, India, and South Korea, encompassing 58% of all reactors built globally. We find that trends in costs have varied significantly in magnitude and in structure by era, country, and experience. In contrast to the rapid cost escalation that characterized nuclear construction in the United States, we find evidence of much milder cost escalation in many countries, including absolute cost declines in some countries and specific eras. Our new findings suggest that there is no inherent cost escalation trend associated with nuclear technology.
