Dear Sir:
The Authority's Implementation Plan for Regulatory Guide 1.97 (Reference 1) included a proposed installation schedule for the FitzPatrick plant.
On January 29, 1985, Authority representa-tives met with the NRC staff to discuss our implementation of the five items in Supplement No. 1 to NUREG-0737.
Subsequently, the NRC requested that the Authority further justify our proposed implementation schedule (Reference 2).
This letter responds to that request.
Attachment No. 1 is a revised implementation schedule for each of the Regulatory Guide 1.97 variables.
This supersedes the schedule included with Reference No.
1.
One new variable (Item No. 18) that was omitted from the prior schedule has been added.
Installation schedules for two variables (Items 22 and 23) have been shortened by one fuel cycle.
Four variables (Items 1, 10, 19, and 22) have extended installation schedules.

F PDR 1
s Attachment No. 2 justifies the revised implementation schedule.
For each Regulatory Guide 1.97 variable, estimates of engineering and design time, procurement and lead times are included.
In general, the engineering and design for each variable will require 10 to 12 months.
This time includes the preparation of procurement documents and the revision of plant drawings.
Because some of the equipment has very long lead times, procurement may require as long as 8 months.
Attachment No. 1 is both a realistic and best schedule for other reasons not described in the justification (Attachment No. 2).
At the January 29th meeting, the Autho ity described the modifi-cations scheduled for installation in upcoming refueling outages.
We are currently working on FitzPatrick plant modifications and improvements with an estimated value in excess of $160,000,000.
A list of some of these modifications and further justification as to why additional improvements cannot be made to this schedule is included with our "ATWS Rule" (10 CFR 50.62) schedule, transmitted under separate cover.
While none of the planned modifications are of such scope or size as to preclude the completion of other modifications, the number which can be safely and effectively implemented at one time is limited.
Physical limitations, such as on-site manpower, as well as fiscal, engineering and procurement limitations can significantly affect schedule.
In some cases, installation sequences can be changed to improve schedules, reduce the amount of duplicate work or to take advantage of developing situations.
Schedule flexibility allows the Authority to both operate FitzPatrick and complete modifications in an efficient, safe and cost-effective manner.
If you have any questions or would like to discuss this further, please contact Mr. J. A. Gray, Jr. of my staff.
Very truly yours o$'nC. Brons Senior Vice President Nuclear Generation J

The implementation schedule for this variable only includes installation of the ability to display it in the Control Room via the SPDS/ EPIC.
This will be completed in accordance with SPDS/ EPIC schedules.
If additional modifications are necessary, they will be completed during " Reload 8/ Cycle 9".
This additional time is required for equipment procurement.
