Fukushima Daini nuclear power plant in context
The 4 units with both construction and grid dates on record took 3.7 to 5.6 years (median 4.7) 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 Onagawa nuclear power plant (127 km) and Kashiwazaki Kariwa nuclear power plant (215 km).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1976 | 1981 | 5.4 | 7.3 (1980s) |
| Unit 2 | 1979 | 1983 | 4.1 | 7.3 (1980s) |
| Unit 3 | 1981 | 1984 | 3.7 | 7.3 (1980s) |
| Unit 4 | 1981 | 1986 | 5.6 | 7.3 (1980s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Onagawa nuclear power plant | Japan | 127 km | 0.8 |
| Kashiwazaki Kariwa nuclear power plant | Japan | 215 km | 1.4 |
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 | Fukushima, Japan |
|---|---|
| Coordinates | 37.3164, 141.0265 |
| Elevation | about 15 mabove sea level |
| Setting | On the sea coast, 0.1 km from the water |
| Region | Eastern Asia |
| Units by status | Retired: 4 |
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.
