Tianwan nuclear power plant

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%.

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.
