The plant Is InMode 3 maintaining Normal Operating Pressure/Normal Operating Temperature.

(NOP/NOT - 5320F1/2155 psig). The licensee expects to maintain the plant Inthese conditions until restart.

LICENSEE ACTIVITIES PRIOR TO RESTART The licensee iscurrently tracking outstanding activates that need to be completed prior to restart

[Mode 2/13. There are approximately 16 restart Items.

• Corrective Actions: 7

• Condition Reports: 1

• Post Maintenance Tests: 2

• Surveillance Tests: 1 NRC ACTIVITIES PRIOR TO RESTART The 0350 Panel completed deliberations on a restart decision and presented an afternoon briefing to Jim Caldwell, Jim Dyer, and Sam Collins on February 23, 2004.

Below Is a simplified time line that describes the significant NRC and licensee activities and milestones that are necessary for NRC to authorize restart.

These tentative dates are predicated upon the licensee successfully completing NRC pre-restart activities and demonstrating acceptable operating performance.

Key Agency decision points are annotated with asterisks (¢) In the timeline below.

The outcome of each decision point could materially alter the timing and substance of the rest of the schedule.

The details of these activities are described In three internal NRC documents: the Davis-Besse Oversight Panel Process Plan, the Davis-Besse Restart Communications Plan and the Davis-Besse Restart Punch List.
