Operating1Pre-construction1Retired1circle area ∝ site capacitydashed = approximate positionThis plant’s position is approximate in the source data, so it may be several kilometres from where it is drawn. Coastlines, borders and lakes: Natural Earth (1:10 million, public domain), which is generalised, so a coastal plant can sit a couple of kilometres off its true shoreline. Site positions: Global Nuclear Power Tracker.
