Dukovany nuclear power plant

Dukovany nuclear power plant is a nuclear power station in Czech Republic with 4 operating units totalling 2,000 MW gross. The site has 6 units on record in total.

Operating4Retired2circle 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.

Dukovany nuclear power plant in context

By gross operating capacity Dukovany nuclear power plant is the 2nd largest of 2 operating nuclear sites in the Czech Republic, holding 48% of the country's operating capacity, and ranks 89th of 172 worldwide.

Its operating units started up between 1985 and 1987; the median unit is 40.0 years old, older than the median of 39.5 in the Czech Republic.

The 4 units with both construction and grid dates on record took 6.1 to 8.3 years (median 7.4) 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 Bohunice nuclear power plant (131 km) and Mochovce nuclear power plant (193 km).

4 operating units are rated differently now from their design net capacities: Unit 1 +11.4%, Unit 2 +12.1%, Unit 3 +11.4% and Unit 4 +12.1%.

The tracker lists a planned retirement year, a forecast and not a decision on record, for 4 operating units: Unit 1 (2037), Unit 2 (2037), Unit 3 (2037) and Unit 4 (2037).

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.
