Mihama nuclear power plant

Mihama nuclear power plant in context

By gross operating capacity Mihama nuclear power plant is the 7th largest of 9 operating nuclear sites in Japan, holding 6% of the country's operating capacity, and ranks 156th of 172 worldwide.

Its operating unit started up in 1976; the unit is 50.0 years old, older than the median of 35.0 in Japan.

The 3 units with both construction and grid dates on record took 3.5 to 3.9 years (median 3.5) from construction start to grid connection; the median across all reactors connected in the 1970s is 5.4 years.

The nearest other tracked nuclear sites are Ohi nuclear power plant (33 km), Takahama nuclear power plant (46 km) and Shimane nuclear power plant (269 km).

The tracker lists a planned retirement year, a forecast and not a decision on record, for 1 operating unit: Unit 3 (2036).

Build time by unit

Nearest tracked nuclear sites

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.
