The Pathfinder Atomic Power Plant, a nuclear power plant built by Northern States Power Company near Sioux Falls, is considered the world's first all-nuclear power plant. After only one year's operation, however, it was converted to a conventional power plant because of technical problems.

Location: Sioux Falls, South Dakota, United States
Type: Boiling Water Reactor (BWR)
Net Output: 59 MWe
Now decommissioned.
Date started: July, 1966
Date closed : October, 1967

The Pathfinder location is now known as Angus Anson Generating Station, which was formally established in 1994, when two peaking units were installed to provide additional generation to the Sioux Falls area. The site previously was home to the Pathfinder plant, which was originally built as a pilot nuclear plant - a facility that laid the groundwork for the company's successful nuclear operations at Monticello and Prairie Island. Pathfinder later was converted to an oil and gas-fired peaking facility, although it is no longer operating.
