. Rockville, MD 20852 On November 9,1998, Transnuclear submitted to your office, responses to NRC's Request for Additional Information (RAI) in support of a General License Application (10 CFR Part 72 Subpart K) for the TN-32 spent fuel storage cask. In addition to the responses, Transnuclear supplied a revised SAR incorporating the additional information requested, revised analyses performed to the Standard Review Plan and other published NRC positions. Duke Energy Corporation (Duke) has actively supported Transnuclear'in the preparation of this submittal.
Transnuclear is under contract to provide TN-32 casks to Duke's McGuire Nuclear Station beginning in January 2000. This delivery date ensures adequate time for training and dry runs, with initial loading scheduled for September 2000.
Duke remains committed to its' selection of the TN-32 design for deployment at McGuire. It is Duke Energy's understanding that this cask design was previously approved by the NRC under a Site Specific License Application (10 CFR Part 72 Subpart B) and subsequently placed l O in service at both the Surry and North Anna Nuclear Stations. Prior regulatory approval under 10 CFR 72 was an important factor in Duke Energy's selection of the TN-32 cask i
for use~at McGuire.
Currently,1067 of the '1463 total spaces are occupied in the Unit 2 spent fuel pool at 0)
McGuire Nuclear Station. Additional space is necessary before the end of cycle 14 0
refueling in December 2001. McGuire Unit 2 will loose prudent reserve margin before this refueling outage. Prudent reserve is the maintenance of adequate space in the fuel L

2 pool at all times to fully offload the core. This ensures that any primary equipment in the reactor coolant system that can only be worked on with the reactor coolant drained can be l
serviced in the event of failure of such equipment.
1 Duke Energy is encouraged by the commitment of the Spent Fuel Project Office to meeting NRC review schedules. However, the recent RAI included significant and detailed format, structure and content change requested by the NRC staff to license basis documentation. Given that the TN-32 design has received Part 72 approval within the last two years and is in service, it would seem that many issues relating to an adequate licensing and design basis have already been established as precedent.
Duke is committed to helping Transnuclear with all the assistance necessary to meet the NRC staffs expectations for providing quality licensing basis documentation. Duke Energy believes that the most recently supplied information should meet the staff's expectations and it is our desire to avoid another formal round of questions if at all possible.
Duke Energy understands that the staff is reviewing the documentation against the Standard Review Plan for Dry Cask Storage Systems (NUREG-1536).
Where Transnuclear has taken exception to this regulatory guidance Duke Energy has asked that a sound bases exist. NUREG-1536 criteria should not be treated as regulatory requirements and appropriate deviations should be acceptable to the NRC staff. This is especially true in this case, where the NRC has granted recent licensing approval of the cask design.
Duke Energy would ask that you work closely with the staff of the Spent Fuel Project Office to provide a timely review of this submittal and to avoid additional formal rounds l
of questions through Requests for Additional Information. Please contact David Jones at (704) 382-4080 or Mike Cash at (704) 875-4117 if you have any questions concerning this matter.
