    • Duke

> Submits License Amendment Request (LAR) on the docket SMakes TDs available off-docket (timing question still open)

S:.NRC

> Reviews LAR and begins drafting the SE

> Identifies specific information that is needed to complete the SE

- Requests via RAIs any specific information that needs to be docketed 7

Wuke Alternative Approach to Ob-I-IL ,nergy TD Docketing (cont.)

o:. Duke submits this specific information on the docket in one or more supplements to the initial LAR and prior to SE being completed

  • 'NRC completes SE referencing docketed information
  • . This approach SAvoids unnecessary docketing of TDs, and

> Supports overall schedule for issuance of the SE
