Hallam nuclear power plant in context
The one unit with both construction and grid dates on record took 4.7 years from construction start to grid connection; the median across all reactors connected in the 1960s is 5.0 years.
The nearest other tracked nuclear sites are Cooper nuclear power plant (99 km) and Wolf Creek nuclear power plant (275 km).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Hallam nuclear power plant | 1959 | 1963 | 4.7 | 5.0 (1960s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Cooper nuclear power plant | United States | 99 km | 0.8 |
| Wolf Creek nuclear power plant | United States | 275 km | 1.3 |
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.
| Location | Nebraska, United States |
|---|---|
| Coordinates | 40.5590, -96.7848 |
| Elevation | about 450 mabove sea level |
| Setting | About 1,200 km from the sea |
| Region | Northern America |
| Units by status | Retired: 1 |
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.
