Ikata nuclear power plant in context
By gross operating capacity Ikata nuclear power plant is the 6th largest of 9 operating nuclear sites in Japan, holding 6% of the country's operating capacity, and ranks 153rd of 172 worldwide.
Its operating unit started up in 1994; the unit is 32.0 years old, younger than the median of 35.0 in Japan.
The 3 units with both construction and grid dates on record took 3.0 to 3.5 years (median 3.5) 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 Genkai nuclear power plant (229 km), Shimane nuclear power plant (236 km) and Sendai nuclear power plant (271 km).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1973 | 1977 | 3.5 | 5.4 (1970s) |
| Unit 2 | 1978 | 1981 | 3.0 | 7.3 (1980s) |
| Unit 3 | 1990 | 1994 | 3.5 | 8.0 (1990s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Genkai nuclear power plant | Japan | 229 km | 2.4 |
| Shimane nuclear power plant | Japan | 236 km | 0.8 |
| Sendai nuclear power plant | Japan | 271 km | 1.8 |
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.

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.
