Oskarshamn nuclear power plant in context

By gross operating capacity Oskarshamn nuclear power plant is the 3rd largest of 3 operating nuclear sites in Sweden, holding 20% of the country's operating capacity, and ranks 116th of 172 worldwide.

Its operating unit started up in 1985; the unit is 41.0 years old, younger than the median of 44.0 in Sweden.

The 3 units with both construction and grid dates on record took 4.8 to 5.1 years (median 5.0) 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 Ringhals nuclear power plant (274 km).

The current net rating of Unit 3 differs from its design net capacity by +33.3% (1,050 MW at design, 1,400 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.
