SUMMARY

OF MEETING WITH COMBUSTION ENGINEERING OWNERS GROUP The subject meeting was held on April 8,1993 at the Nuclear Regulatory Commission (NRC) Headquarters in Rockville, Maryland. The objectives of the meeting were to facilitate communications between the Combustion Engineering Owners Group (CE0G) and the NRC, to summarize active CEOG programs, to review the status of CEOG submittals, and to discuss issues 'of concern to the NRC.

Enclosed is a copy of the meeting. agenda, the CE0G presentation slides, the meeting attendance list, and topical report review status.

A member of each CE0G subcommittee provided an overview of the issues being addressed, CE0G and NRC interactions on the issues, status, and requested NRC action.

Each subcommittee presenter also gave details of other activities being worked on by the Owners Group.

The status of various CE0G submitted CE topical reports was discussed during the presentations. As in previous CE0G-NRC meetings, the NRC stressed that the schedule of the review of topical reports could be affected by NRC resource limitations.

A question was raised by Dr. Murley to the CE0G Licensing Subcommittee regarding license renewal of CE plants. The CE0G has stated that it is working on a first phase of the renewal issue with EPRI and that it may later identify a lead plant for review. Dr. Murley encouraged the CE0G's efforts and stated that instead of focusing on a lead plant approach the CEOG should try to resolve as many license renewal issues as possible on a generic CE basis.
