Callaway nuclear power plant in context

By gross operating capacity Callaway nuclear power plant is the 39th largest of 54 operating nuclear sites in the United States, holding 1% of the country's operating capacity, and ranks 127th of 172 worldwide.

Its operating unit started up in 1984; the unit is 42.0 years old, younger than the median of 45.0 in the United States.

The one unit with both construction and grid dates on record took 9.1 years 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 Clinton nuclear power plant (298 km).

The current net rating of Unit 1 differs from its design net capacity by +3.8% (1,171 MW at design, 1,215 MW now).

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.
