ABSTRACT

Commercial nuclear power plants in this country can be owned by a number of separate

entities, each with varying ownership proportions. Each of these owners may, in turn, have a

parent/subsidiary relationship to other companies. In addition, the operator of the plant may be

a different entity as well. This report provides a compilation on the owners/operators for all

commercial power reactors in the United States. While the utility industry is currently

experiencing changes in organizational structure which may affect nuclear plant ownership, the

data in this report is current as of August 2001. The report is divided into sections representing

different aspects of nuclear plant ownership.
