NRC Clinton Special Evaluation Team Report
Mr. Larry HaabChief Executive OfficerIllinois Power Company550 S. 27th Street Decatur, IL 62717
Dear Mr. Haab:
This letter forwards the Special Evaluation Team (SET) report for the Clinton Power Station (CPS). The decline in performance of CPS became apparent to the NRC in September 1996. This trend was documented in a letter to you dated January 27, 1997.At the June 1997 Senior Management Meeting, the NRC decided that CPS should remain on the list of plants with a declining performance trend and that a

The ISA, conducted from August through October 1997, identified significant weaknesses in operations, engineering, maintenance, and plant support.Examples of these weaknesses occurred in conduct of operations, management and supervision of operations, performance of system engineers, control andunderstanding of the design bases, maintenance work scheduling and work processes, and radiation protection. In addition, the ISA identified a number of weaknesses in the barriers to prevent safety problems that are not typical of facilities with a strong nuclear safety culture. These weak barriers were found atall levels of management associated with CPS and were

Illinois Power said itwill purchase at least 75 percent of the Clintonplant's electricity output through 2004.
