SUMMARY
OF OCTOBER 12, 2005, CATEGORY 1 WORKING-LEVEL MEETING WITH PPL AND FRAMATOME ADVANCED NUCLEAR POWER (FANP) TO DISCUSS THE LICENSEES PROPOSED EXIGENT TECHNICAL SPECIFICATION REQUEST RELATED TO MINIMUM CRITICAL POWER RATIO SAFETY LIMIT (MCPRSL) AND CONTROL CELL FRICTION ISSUES AT SSES 1 On October 12, 2005, a public meeting was held between the U.S. Nuclear Regulatory Commission (NRC), and representatives of PPL and Framatome Advanced Nuclear Power (FANP) at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting was to conduct a working-level discussion related to the schedule, approach, and strategy for the SSES 1 revised core design Cycle 14 (U1C14A) and Cycle 15 (U1C15) MCPRSL amendment request in light of the control rod friction issues experienced on SSES-1.
PPL presented an overview of the current SSES 1 operations relative to PPLs Control Cell Channel Management Action Plan by describing the evaluation, analysis, and the compensatory actions completed following the rod sequence exchange in June 2005 in which control rod friction conditions were observed. PPL explained their decision to initiate a mid-cycle outage and core redesign to address the control rod friction conditions in the core.
They described their friction mitigation plan and strategy to definitively characterize the source of the friction and confirm the subsequent actions for reducing or eliminating the friction. PPL indicated that they plan to maintain the original SSES 1 core design parameters by (1) re-channeling the suspect fuel, (2) discharging and replacing the suspect fuel with previously discharged ATRIUM-10 fuel, and (3) shuffling the non-suspect fuel to affected locations. PPL stated that the most probable cause of the channel deformation in SSES 1 is due to shadow corrosion induced channel bow, and that additional inspections and analyses during the mid-cycle outage will be used to reach a definitive root cause. Finally, PPL provided the basis for the channel bow assumptions and calculations for both the original design and the redesigned U1C14A MCPRSL.

PPL Susquehanna, LLC In addition, PPL provided an overview of their proposed U1C15 MCPRSL amendment request which is scheduled to be submitted in November 2005. PPL indicated that the U1C14A design will preserve the U1C15 beginning-of-life characteristics as much as practicable. The U1C15 design may require minor changes in order to minimize U1C14 effective control blade exposure on U1C15.
The business portion of the meeting concluded with the licensee requesting any feedback from the NRC staffs preliminary review of their application. The NRC staff informed PPL that a request for additional information would be generated in the near term and that the staff would be ready to support this review on an exigent basis.
A representative from Alleghany Electric Cooperative, Inc., Mr. Lance Hubbard, was in attendance. There were no other members of the public in attendance. Optional public meeting feedback forms (NRC Form 659) were available at the meeting, but none were completed. is a list of the meeting attendees, and Enclosure 2 is a copy of the licensees slides presented at the meeting.
