Cernavodă

Cernavodă (, historical names: Thracian: Axiopa, Axiopolis, Черна вода Cherna voda, Boğazköy) is a town in Constanţa County, Dobrogea, Romania with a population of 20,514.

The town's name is derived from the Slavic (more precisely Bulgarian) černa voda (черна вода in Cyrillic), meaning "black water". This name is regarded by some scholars as a calque of the earlier Thracian name Axíopa, from IE *n.ksei "dark" and upā "water" (cf. Avestan axšaēna "dark" and Lithuanian ùpė "river, creek").

Economy
The town is a Danube fluvial port, and it houses the Cernavodă Nuclear Power Plant, consisting of two CANDU reactors providing about 18% of Romania's electrical energy output. The second reactor was built through a joint venture between Canada's Atomic Energy of Canada Limited and Italy's ANSALDO and become fully functional in November 2007.

The Danube-Black Sea Canal, opened in 1984, runs from Cernavodă to Agigea and Năvodari.
