FORT CALHOUN, Neb. (AP) — Omaha Public Power District officials are considering closing a more than 40-year-old nuclear power plant in Fort Calhoun, causing concerns about the potential economic fallout.

Officials announced potential plans Thursday to close the Fort Calhoun Nuclear Station at the end of the year. The district chief executive has recommended the closure, but the move still requires the utility board’s approval next month.

About 150 of the nearly 700 workers at the plant live in Fort Calhoun, Blair or elsewhere in Washington County. Local businesses often reap benefits from workers who commute there.

A local economic development official says there is enough time to assess the workers’ skills and find a way to keep them in the area.
