Dear Sir:

NRC Generic Letter (GL) 89-10, Supplement 6, "Information on Schedule and

-Grouping, and Staff Responses to Additional Public Questions," states that if a licensee intends to extend its current schedular commitment for verifying the capability of motor operated valves (MOVs) within the scope of GL 89-10, the following information shall be submitted at least 60 days prior to the current commitment date,

. to assist the staff in evaluating the licensee's justification for extending the GL 89-10 test program for capability verification and establishing appropriate audit / inspection plans' and schedules:

(1) the completion status of the licensee's GL 89-10 program as of the current commitment date; (2) for those' MOVs whose capability will not be verified by dynamic testing by the current commitment date;

(a) for each valve: the valve type, size, safety function, design-basis q differential pressure and flow, and the'available valve factor (or similar capability measure), and a discussion of the relative' risk ,

significance of the valves involved; (b) confirmation that the functionality of these MOVs has been .

established using the best availtsble information; and the schedule for completing both the MOV testing and any needed I (c) corrective actions. i PECO Energy Company (PECO Energy) expects to have completed all its MOV testing

- commitments and have all valves set up with the best available data, as documented in the referenced letters, by the end of the Peach Bottom Atomic Power Station - l (PBAPS) Unit 3 refueling outage 3R10. However, new data obtained from outage testing must be assessed and compared to the best available information used to set - ,

up PBAPS Unit 3 MOVs to ensure that the most appropriate test data has been-  !

applied.'. Therefore, the purpose of this letter is to request a 90 day schedule extension beyond the originally committed to completion date to perform this additional assessment / reconciliation.

We are providing the following information pursuant to GL 89-10, Supplement 6, to support our extension request:

(1) The current schedule commitment for PBAPS Unit 3 is the end of the' upcoming refueling m*aca 3R10, which is the third refueling outage since the . issuance of - '

GL 89-10. As indicated above, PECO Energy _ expects to have completed all of .

the actions in accordance with its commitments by the end of this outage, currently expected to be mid October,1995.

Many individual tasks are required to complete PECO Energy commitments to i confirm the capability of each of the MOVs in the PBAPS Unit 3 GL 89-10  !

i Program by the end of 3R10. These activities include: static testing, revising switch settings, modifications, and dynamic testing, some of which will be done.

during power ascension at the end of the outage, in order to provide sufficient time for a thorough and accurate assessment of the results of these efforts, PECO Energy is hereby requesting a 90 day extension of the GL 89-10 Program for PBAPS Unit 3.

(2) As discussed below, all testing commitments and capability verifications are.

expected to be completed by the end of 3R10; therefore, the valve specific information, as addressed in GL 89-10 Supplement 6, item 2, need not be submitted. Valves tested during the outage will have their opersbility confirmed and an assessment of their design basis capability performed prior to the end

- ' ' August 2,1995 Page 3 4

of the outage. Assessment / reconciliation of outage test results to other applicable valves may take up to 90 days beyond the completion of the outage.

However, these other applicable valves will have been set up prior to the end of the refueling outage using assumed bounding design parameters established with the best available dynamic. test data, and will be considered capable based on that data. Should any valve be found not capable as a result of the subsequent reconciliation, non-conformance reports will be initiated and appropriate actions taken.

If you have any questions or require additional information regarding this extension request, please contact us.

Sincerely, G. A. Hunger, r.,

Director - Licensing
