A general view of Cernavoda Nuclear Power Plant (CNE Cernavoda) in Cernavoda city, next to Danube-Black Sea channel September 3, 2025. The Nuclear Power Plant in Cernavodă is the only nuclear power plant in Romania. It produces around 20% of the country's electricity. The nuclear plant uses CANDU (Canada deuterium uranium) reactor technology from AECL (Atomic Energy of Canada Limited). The initial plan was to build four units, and schedule their startup from 1985 onward. A fifth unit was subsequently planned on the direct orders of Communist leader Nicolae Ceausescu. Units 1 and 2 are currently operational. Three more partially completed CANDU reactors exist on the same site, numbered Unit 3 to Unit 5.,Image: 1035512432, License: Rights-managed, Restrictions: , Model Release: no , Credit line: Daniel MIHAILESCU / AFP / Profimedia
