Chinon nuclear power plant in context
By gross operating capacity Chinon nuclear power plant is the 7th largest of 18 operating nuclear sites in France, holding 6% of the country's operating capacity, and ranks 26th of 172 worldwide.
Its operating units started up between 1984 and 1988; the median unit is 40.5 years old, younger than the median of 41.0 in France.
The 7 units with both construction and grid dates on record took 5.4 to 6.8 years (median 6.1) 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 Civaux nuclear power plant (93 km), Saint-Laurent nuclear power plant (120 km) and Dampierre nuclear power plant (186 km).
2 operating units are rated differently now from their design net capacities: Unit B-1 +4.0% and Unit B-2 +4.0%.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit A-1 | 1957 | 1963 | 6.4 | 5.0 (1960s) |
| Unit A-2 | 1959 | 1965 | 5.6 | 5.0 (1960s) |
| Unit A-3 | 1961 | 1966 | 5.4 | 5.0 (1960s) |
| Unit B-1 | 1977 | 1982 | 5.7 | 7.3 (1980s) |
| Unit B-2 | 1977 | 1983 | 6.7 | 7.3 (1980s) |
| Unit B-3 | 1980 | 1986 | 6.1 | 7.3 (1980s) |
| Unit B-4 | 1981 | 1987 | 6.8 | 7.3 (1980s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Civaux nuclear power plant | France | 93 km | 3.1 |
| Saint-Laurent nuclear power plant | France | 120 km | 1.9 |
| Dampierre nuclear power plant | France | 186 km | 3.7 |
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.
