Chooz nuclear power plant in context

By gross operating capacity Chooz nuclear power plant is the 12th largest of 18 operating nuclear sites in France, holding 5% of the country's operating capacity, and ranks 39th of 172 worldwide.

Its operating units started up in 2000; the median unit is 26.0 years old, younger than the median of 41.0 in France.

The 3 units with both construction and grid dates on record took 5.3 to 12.7 years (median 11.3) from construction start to grid connection; the median across all reactors connected in the 1990s is 8.0 years.

The nearest other tracked nuclear sites are Tihange nuclear power plant (60 km), Cattenom nuclear power plant (127 km) and Doel nuclear power plant (142 km).

2 operating units are rated differently now from their design net capacities: Unit B-1 +3.1% and Unit B-2 +3.1%.

Nearest tracked nuclear sites

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.
