The South Koreans only build reactors that fast when building in South Korea. http://www.world-nuclear.org/information-library/country-profiles/countries-t-z/united-arab-emirates.aspx http://www.world-nuclear.org/information-library/country-pro... Barakah 1, built in the UAE by South Korea, was originally supposed to take 5 years, operating in 2017. It has been delayed a couple of times. Bad news from December 2018: "Cracks found in containment building of UAE nuclear power plant built by S. Korean companies" http://english.hani.co.kr/arti/english_edition/e_international/874728.html http://english.hani.co.kr/arti/english_edition/e_internation... It may still start in 2019. We'll see. But we're already at nearly 7 years. Also, "countries like South Korea" is a club consisting of South Korea and nobody else. Other countries touted for their continued embrace of nuclear power, like Russia, China, and France, don't build reactors that quickly. If you want information right from the source, use the IAEA's Power Reactor Information System and look at the time between construction start and first grid connection for commercially operating reactors. Here's France: https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails.aspx?current=FR https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails.... Their newest commercially operating reactor Civaux 2 took 8 years between construction start and grid connection. They have another, Flamanville 3, that will be newer when/if completed, but it has been under construction for 11 years. Russia: https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails.aspx?current=RU https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails.... Latest commercially operating reactor Leningrad 2-1 took 9 years. China: https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails.aspx?current=CN https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails.... Newest commercial reactor Hayiang-2 took 8 years.
