There are 443 nuclear power plants (NPP) currently (2018) in operation in 30 countries for the purpose of generating electrical power. In the future old systems will be decommissioned and new ones will be planned and built. How the share of energy produced by NPPs will develop is not exactly predictable at the time of writing due to economic and political uncertainties. The production however may be slowly decreasing or constant; but it is quite possible that a gentle increase of the share of energy from NPP’s could occur in the future. At present, 55 NPPs are under construction against 166 that are now decommissioned and shut down.
