Nuclear Power: Strategic Asset, Liability or Increasingly Irrelevant?
The World Nuclear Industry Status Report 2018 Released
Paris, London, 4 September 2018. Nuclear power plants added a total of 7-gigawatt (
GW
) capacity to the world’s electricity grids in 2017 and the first half of 2018, a tiny fraction of the total from all sources, which is estimated at some 257
GW
(net) in 2017, including 157
GW
of renewable capacity (the largest increase ever). Over that 18-month period, six reactors started up in China, two in Russia and one in Pakistan. For the third year in a row, excluding China, global nuclear power generation has declined, finds the World Nuclear Industry Status Report 2018 (
