Donald C Cook nuclear power plant

Donald C Cook nuclear power plant in context

By gross operating capacity Donald C Cook nuclear power plant is the 19th largest of 54 operating nuclear sites in the United States, holding 2% of the country's operating capacity, and ranks 71st of 172 worldwide.

Its operating units started up between 1975 and 1978; the median unit is 49.5 years old, older than the median of 45.0 in the United States.

The 2 units with both construction and grid dates on record took 5.9 to 9.0 years (median 7.4) 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 Palisades nuclear power plant (44 km), Dresden nuclear power plant (156 km) and Braidwood nuclear power plant (160 km).

The current net rating of Unit 2 differs from its design net capacity by +6.2% (1,100 MW at design, 1,168 MW now).

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.
