Saeul nuclear power plant

Saeul nuclear power plant is a nuclear power station in South Korea with 2 operating units totalling 2,979 MW gross. The site has 4 units on record in total.

Operating6circle area ∝ site capacity Coastlines, borders and lakes: Natural Earth (1:10 million, public domain), which is generalised, so a coastal plant can sit a couple of kilometres off its true shoreline. Site positions: Global Nuclear Power Tracker.

Saeul nuclear power plant in context

By gross operating capacity Saeul nuclear power plant is the 3rd largest of 8 operating nuclear sites in South Korea, holding 11% of the country's operating capacity, and ranks 42nd of 172 worldwide.

Its operating units started up between 2016 and 2019; the median unit is 8.5 years old, younger than the median of 27.0 in South Korea.

The 2 units with both construction and grid dates on record took 7.2 to 9.7 years (median 8.5) 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 Shin-Kori nuclear power plant (0 km), Kori nuclear power plant (1 km) and Wolsong nuclear power plant (45 km).

2 operating units are rated differently now from their design net capacities: Unit 1 +5.7% and Unit 2 +5.8%.

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.

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.
