Subject:
Dresden Unit 1 Project Schedule NRC Docket No. 50-10
Dear Mr. O'Connor:
This is to confirm our phone conversation on May 5, 1980 between yourself, Mr.
W.
Stiede, Mr. R.
Janecek, Mr. J. White, Mr. P.
Steptoe and myself regarding the current projected schedule for return to service of Dresden Unit 1.
As requested, attached is a simplified bar chart showing the schedule for all major activities required for return to service.
Those projects dependent on the completion of chemical cleaning are identified by an asterisk.
Several important points must be considered in reviewing this information.
As indicated, the completion of HPCI is critical path to the scheduled return of service.
A May 27th chemical cleaning is dependent on receiving NRC approval by May 12th.
The schedule is also based on manpower availability, for both craft labor and station personnel, and on Dresden Unit 2 refueling outage scheduled for January, 1981.
Consideration of physical space limitations restrict' the number of personnel working in any one area.
The period following the In Service Inspection is required for procurement and installation of material to correct any potential deficiencies.
The completion of chemical cleaning on schedule will reduce the man-rem incurred on all activities within the sphere.
Maintaining the present chemical cleaning project team and support will cost approximately $200,000 per month of delay.
A delay in the return to service will also result in $2,000,000 per month replacement energy costs.
If you have any additional questions please contact us.
Ver/ truly yours, M
h D. L. Peoples Director of Nuclear Licensing omb/3560A Attachments
