Operating1circle area ∝ site capacity 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.

Operating fleet by type: PWR (4). Principal operator: MVM Paks Nuclear Power Plant.

Fuel supply exposure

The fuel families Hungary's operating reactors take, and the fabricators our sources document as able to make each. This is capability, not contracts: it does not say who actually supplies a given plant.
