On August 16, 2006, a telephone conversation was held between Duke,personnel and the NRC staff concerning the proposed admi'nistrative controls to adequately close containment penetrations if necessary during refueling operations.

U.S. Nuclear Regulatory Commission August 31, 2006 Page 2 The additional commitments are as follows:
- 1. Controls will be established to maintain the containment equipment hatch closed and held in place by a minimum of four bolts during movement of irradiated fuel assemblies within containment.
This closure control will remain in place until a prompt closure method is developed.
- 2. Other penetrations open during movement of irradiated fuel assemblies within containment shall have the ability to be closed promptly within approximately 30 minutes.
- 3. The penetration closure method will be robust enough to limit dose and allow the containment purge system to function adequately.
- 4. The procedure changes necessary to implement the administrative controls will be in place prior to implementing an approved License Amendment.
- 5. Personnel training for prompt closure will be conducted prior to opening a penetration during movement of irradiated fuel assemblies within containment.
With this letter, Duke is also requesting a change to the implementation grace period for this License Amendment Request (LAR) from 30 days to 60 days.
This is requested due to the extensive document changes necessary to implement this LAR.
The conclusions reached in the original determination that the LAR contains No Significant-Hazards Considerations and the basis for the categorical exclusion from performing an Environmental/Impact Statement have.not changed as a result of these additional commitments.
