Peach Bottom nuclear power plant in context

By gross operating capacity Peach Bottom nuclear power plant is the 4th largest of 54 operating nuclear sites in the United States, holding 3% of the country's operating capacity, and ranks 45th of 172 worldwide.

Its operating units started up in 1974; the median unit is 52.0 years old, older than the median of 45.0 in the United States.

The 3 units with both construction and grid dates on record took 5.0 to 6.6 years (median 6.1) 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 Hope Creek nuclear power plant (71 km), Salem nuclear power plant (71 km) and Limerick nuclear power plant (78 km).

2 operating units are rated differently now from their design net capacities: Unit 2 +22.1% and Unit 3 +25.0%.

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.
