Tianwan nuclear power plant in context

By gross operating capacity Tianwan nuclear power plant is the 3rd largest of 18 operating nuclear sites in China, holding 10% of the country's operating capacity, and ranks 4th of 172 worldwide.

Its operating units started up between 2007 and 2021; the median unit is 8.0 years old, younger than the median of 10.0 in China.

The 6 units with both construction and grid dates on record took 4.6 to 6.6 years (median 5.0) from construction start to grid connection; the median across all reactors connected in the 2010s is 5.9 years.

The nearest other tracked nuclear sites are Haiyang nuclear power plant (284 km).

4 operating units are rated differently now from their design net capacities: Unit 1-1 +1.0%, Unit 1-2 +1.0%, Unit 3-5 +6.0% and Unit 3-6 +6.0%.

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.
