power grid
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power ...
. All commercial nuclear reactors use nuclear fission. As of November 2022, there are 438 operable power reactors in the world, with a combined electrical capacity of 394 GW. Additionally, there are 60 reactors under construction and 103 reactors planned, with a combined capacity of 66 GW and 105 GW, respectively, while 325 more reactors are proposed.
