Licensing Approach
- 1 OCFR72.42 provides for license renewal
- "Applications... should be filed in accordance with applicable provisions of subpart B at least two years prior to the expiration of the existing license."
(i.e. by January 31, 2008 for Oconee ISFSI)
- "...the existing license shall not expire until a final decision... has been made by the Commission."
- Duke will request 40 year renewal term
- Exemption from 1 OCFR72.42(a) needed?

Duke Energy.
Licensing Approach
- "Preliminary Guidance for License Renewal for Site-Specific Independent Spent Fuel Storage Installations (ISFSIs)", March 2001
" Specifies content determined to meet 1 QCFR72.42 requirements (nine specific topics)
- Provides additional guidance for Aging Management Review process and Aging Management Programs
" Precedent
" Previous ISFSI license renewals (Surry and Robinson)
" Duke Part 54 renewals for reactors 18
