Kalpakkam nuclear power plant in context
The nearest other tracked nuclear sites are Madras nuclear power plant (0 km).
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Madras nuclear power plant | India | 0 km | 0.2 |
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 Kalpakkam 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 | Tamil Nadu, India |
|---|---|
| Coordinates | 12.5531, 80.1733 |
| Elevation | about 5 mabove sea level |
| Setting | On the sea coast, 1.1 km from the water |
| Region | Southern Asia |
| Units by status | Under construction: 1 Announced: 2 |
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.
