SUMMARY
OF MEETING WITH PENNSYLVANIA POWER AND LIGHT COMPANY REGARDING THE POWER UPRATE SUBMITTAL FOR SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1
AND 2 (TAC NOS.
M83426 AND H83427)
A meeting was held on August 5, 1992, at NRC Headquarters, between members of the NRC staff and representatives of the licensee and General Electric (GE).
The purpose of the meeting was to discuss PP&L's licensing strategy and NRC staff schedules for the technical review of the licensee's power uprate submittal, A list of attendees is enclosed (Enclosure 1).
Discussions were made on many facets of the licensee's approach to power uprate for SSES, Units 1 and 2.
The more significant items discussed pertained to the licensee's schedule for the various sections of the power uprate submittal and the NRC staff review schedule.
The PP&L power uprate submittals incorporate increased core flow and the use of the GE codes SAFER/GESTR as applied to Siemens Nuclear Power Corporation (SNP) fuels.
To facilitate the NRC staff review, the licensee has closely followed the approach used by Fermi in addressing power uprate and will postpone submittal of related technical specification changes until power uprate is to be implemented on each unit.
The current schedule for the completion of the technical staff review of PP8 L's power uprate submittals is targeted for July 1993.
The attending staff wa's satisfied with the licensee's approach and was confident that the review could be completed on or ahead of this schedule.
The licensee currently plans to implement power uprate on Units 1 and 2 in May 1995 and May 1994, respectively.
The slides presented at the meeting are enclosed (Enclosure 2),
