Zaporizhzhia nuclear power plant in context

By gross operating capacity Zaporizhzhia nuclear power plant is the 1st largest of 4 operating nuclear sites in Ukraine, holding 43% of the country's operating capacity, and ranks 8th of 172 worldwide.

Its operating units started up between 1985 and 1996; the median unit is 38.5 years old, younger than the median of 39.0 in Ukraine.

The 6 units with both construction and grid dates on record took 3.8 to 9.4 years (median 4.7) from construction start to grid connection; the median across all reactors connected in the 1980s is 7.3 years.

The nearest other tracked nuclear sites are South Ukraine nuclear power plant (254 km).

Build time by unit

Unit	Construction start	Grid connection	Years	Fleet median, same decade
Unit 1	1980	1984	4.7	7.3 (1980s)
Unit 2	1981	1985	4.6	7.3 (1980s)
Unit 3	1982	1986	4.7	7.3 (1980s)
Unit 4	1983	1987	4.7	7.3 (1980s)
Unit 5	1985	1989	3.8	7.3 (1980s)
Unit 6	1986	1995	9.4	8.0 (1990s)

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.

Site detail

Location	Zaporizka, Ukraine
Coordinates	47.5067, 34.5851
Elevation	about 25 mabove sea level
Setting	On the shore of a large lake, 2.5 km from the water
Region	Eastern Europe
Units by status	Operating: 6

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.
