OR NP FOaRi fJ&I bSE ONLY DAVIS-BESSE RESTART STATUS This Information Is current as of 3:30 pm (EST) on February 13, 2004.
The plant Is In Mode 3 maintaining Normal Operating PressurelNormal Operating Temperature.
(NOP/NOT - 5320F/2155 psig). The licensee expects to maintain the plant In these conditions until restart. The plant Is In Day 2 of a planned entry into a 72-hour Technical Specification Action Statement Involving the Component Cooling Water Room Ventilation System.
LICENSEE ACTIVITIES PRIOR TO RESTART The licensee Is currently tracking outstanding activities that need to be completed prior to restart
[Mode 2/1]. There are approximately 37 restart items.
Corrective Actions:
14 Condition Reports:
7 Field Work:
3 Surveillance Tests:
1 NRC ACTIVITIES PRIOR TO RESTART The public meeting with the licensee to discuss the plant's readiness for restart was last night, February 12h, near the site at Camp Perry. The meeting was very interactive. The NRC received the licensee's request for restart and the staff communicated that the 0350 process continues. The NRC stated that the Oversight Panel was not ready to authorize restart and that the Panel had outstanding Issues that remain to be resolved.
A pubic meeting to discuss the preliminary findings of the followup Restart Readiness Assessment Team Inspection and the followup Management and Human Performance Inspection was held earlier In the day at Camp Perry, prior to the evening restart meeting.
Region Ill Division of Reactor Safety completed a week long baseline Emergency Preparedness Inspection onsite and held a debrief with the licensee today, February 13d'. The Inspection focused on a review of site-specific Emergency Action Levels (EALs). The initial result of this review concluded that there are no decreases in effectiveness issues with the Davis/Besse EALs which would affect restart.
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 SENi 1VE INFORMATION - FOR 0 RA§M SE13NL'I'~

Repairs to the startup transformer are expected to be completed by February 1 41h.
LICENSEE ACTIVITIES FOLLOWING RESTART AUTHORIZATION The following sequence of events were taken from a licensee Level 1 schedule.
NRC approval for restart Enter operational Mode 2 (reactor startup)
Reactor critical - Zero power physics testing Enter Mode 1 (greater than 6% power)
