Angra nuclear power plant

Angra nuclear power plant is a nuclear power station in Brazil with 2 operating units totalling 1,990 MW gross. The site has 3 units on record in total.

Operating1circle 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.

Angra nuclear power plant in context

Angra nuclear power plant is the only operating nuclear site in Brazil on record, so it holds all of the country's operating capacity, and ranks 92nd of 172 operating sites worldwide by gross capacity.

Its operating units started up between 1985 and 2001; the median unit is 33.0 years old.

The 2 units with both construction and grid dates on record took 10.9 to 24.6 years (median 17.7) from construction start to grid connection; the median across all reactors connected in the 2000s is 6.8 years.

No other nuclear site with an exact position in this dataset lies within 300 km.

The current net rating of Unit 2 differs from its design net capacity by +2.4% (1,245 MW at design, 1,275 MW now).

Build time by unit

UnitConstruction startGrid connectionYearsFleet median, same decade
Unit 11971198210.97.3 (1980s)
Unit 21976200024.66.8 (2000s)

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.
