Großwelzheim nuclear power plant in context
The nearest other tracked nuclear sites are Cattenom nuclear power plant (211 km), Tihange nuclear power plant (269 km) and Leibstadt nuclear power plant (279 km).
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Cattenom nuclear power plant | France | 211 km | 5.4 |
| Tihange nuclear power plant | Belgium | 269 km | 1.1 |
| Leibstadt nuclear power plant | Switzerland | 279 km | 1.3 |
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.
| Location | Bayern, Germany |
|---|---|
| Coordinates | 50.0581, 8.9869 |
| Elevation | about 105 mabove sea level |
| Setting | About 360 km from the sea |
| Region | Western Europe |
| Units by status | Retired: 1 |
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.
