The Entergy Nuclear subsidiary owns, operates, supports and provides management services to a national fleet of reactors in eight locations in the United States. 

With the purchase of Pilgrim Nuclear Power Station in 1999, Entergy was the first company in the U.S. to acquire an operating nuclear plant through competitive bidding.

In another first, Entergy obtained a management contract in 2002 providing support and management services to Cooper Nuclear Station in Nebraska. The contract with Cooper's owner, Nebraska Public Power District, has been subsequently extended until 2029.
