Each unit's rating, type and milestone dates as recorded by the Global Nuclear Power Tracker, with any correction we made to it. A dash or "not disclosed" means the source does not give the value.
Cernavodă nuclear power plant in context
Cernavodă nuclear power plant is the only operating nuclear site in Romania on record, so it holds all of the country's operating capacity, and ranks 117th of 172 operating sites worldwide by gross capacity.
Its operating units started up between 1996 and 2007; the median unit is 24.5 years old.
The 2 units with both construction and grid dates on record took 13.3 to 24.1 years (median 18.7) from construction start to grid connection; the median across all reactors connected in the 2000s is 6.8 years.
No other nuclear site with an exact position in this dataset lies within 300 km.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1983 | 1996 | 13.3 | 8.0 (1990s) |
| Unit 2 | 1983 | 2007 | 24.1 | 6.8 (2000s) |
How these are worked out: ranks use gross operating capacity; ages count from the start-up year on record, as on the age page; build times run from construction start to grid connection, as on the build-times page; ratings are the tracker's net and design net capacity, as on the uprates page. Distances are straight-line between exact positions, so a site with only an approximate position gets none. A unit missing a date or a rating is left out of the figure that needs it.

Elevation is read at the listed coordinates from a 30 m terrain model (SRTM 30 m). Two independent models differ by a median of 6 m across our plants and by up to about 40 m on steep or coastal ground, and a point on a shoreline can read as sea level. Distance to the water is measured to a generalised 1:10 million coastline, so a few kilometres or less is not resolved. This is context, not a design-basis or flood-risk figure.
