Global Nuclear Power Generation

Nuclear power generation rose by 3.7% between 2018 and 2019, representing the seventh annual increase in a row. The share of nuclear in the global power generation mix inched up from 10.2% to 10.4%. There are currently 453 reactors in operation in 31 countries. Nuclear power generation in Japan continued to rise over the period (up 33%) as the reactors shut down after Fukushima were gradually brought back on stream. China steadily developed its installed capacity, adding 20% from 2018 to 2019. France’s output, on the other hand, dropped owing to maintenance problems (the Fessenheim plant closed in 2020). German nuclear power generation continued to decline, albeit at a slower pace than in previous years.
