'RBSTART SCHBDULB BXTBNSION The purpose of this letter is to advise you of changes to the Cook Nuclear Plant restart plan and schedule.

You were previously advised of our plans for restart during the course of the 0350 meetings. Based on our current progress in the Restart Plan and the best available information, our restart has been delayed until first quarter 1999. This schedule change is necessary to support an improved sequence to support ice basket repair quality requirements, additional scope due to ice basket inspections, and to integrate engineering work items associated with validating the ice condenser design basis. Attachment 1'.

provides the top level schedule with additional detail.

We have recently approved a revision to the final restart plan.

This revision updates the plan to include: actions associated with the 0350 restart checklist; control of the management review board condition report review process; expansion of roles and responsibilities; directions for completion of action plans; restructuring the plan to reflect restart process elements; and improved schedule change control. Attachment 2 provides a copy of revision 3 to the Restart Plan for your use in follow-up inspection activities.

It is recognized that there are potential challenges to the schedule, which we will continue to pursue until appropriately resolved. As one example, we are implementing a thorough vertical slice inspection of our auxiliary feedwater system. Any findings during this inspection will be evaluated for possible impact on previously completed system reviews and re-inspections of systems which may impact the current schedule for completion of restart activities. Further,' detailed validation of the updated final safety analysis report is in progress for 21 selected risk significant systems. Appropriate disposition of any discrepancies discovered during the validation may also represent a schedule 980922004b 9809lb PDR ADOCK 050003i5 P PDR J

U.S. Nuclear Regulatory Commission AEP:NRC:1260GF Page 2 challenge. Finally, to provide reasonable assurance that our restart plan is thorough and adequate to address significant concerns, we are in the process of reviewing and validating our strategies for addressing the fundamental root causes of the extended shutdown and major hardware programmatic problems.

Following this review, additional actions may be'onsidered that have the potential for schedule impact.

We will continue to advise you of our progress to address restart issues or schedule adjustments through the 0350 process. Please advise if you have any questions.

Sincerely, R. P. Powers Vice President
