Flamanville nuclear power plant in context
By gross operating capacity Flamanville nuclear power plant is the 4th largest of 18 operating nuclear sites in France, holding 7% of the country's operating capacity, and ranks 16th of 172 worldwide.
Its operating units started up between 1986 and 2024; the median unit is 39.0 years old, younger than the median of 41.0 in France.
The 2 units with both construction and grid dates on record took 6.0 to 6.2 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 Paluel nuclear power plant (185 km), Hinkley Point nuclear power plant (206 km) and Penly nuclear power plant (227 km).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1979 | 1985 | 6.0 | 7.3 (1980s) |
| Unit 2 | 1980 | 1986 | 6.2 | 7.3 (1980s) |
1 further unit at this site lacks a construction or grid date on record and is left out.
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Paluel nuclear power plant | France | 185 km | 5.5 |
| Hinkley Point nuclear power plant | United Kingdom | 206 km | - |
| Penly nuclear power plant | France | 227 km | 2.8 |
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.

Magnitude 4.0 and above within 200 km of Flamanville nuclear power plant's listed coordinates, past 30 days. This is distance, not shaking: it says nothing about damage or any change in operation. Every plant.
| Location | Normandie, France |

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.
