SUBJECT:

Peach Bottom Atomic Power Station, Units 2 and 3 Limerick Generating Station, Units 1 and 2 Generic Letter 89-10. " Safety-Related Motor-Operated Valve Testing and Surveillance - 10 CFR 50.54 (f)"

Changes to Testing Program Commitments Gentlemen:

The NRC lssued Gener'c Letter (GL) 89-10, " Safety-Related Motor-Operated Valve Testing and Surveillance -10 CFR 50.54(f)," on June 28,1989, requesting that licensees develop and implement a program for the testing, inspection, and maintenance of safety-related motor-operated valves (MOVs) to provide the assurance that safety-related MOVs will function properly when subjected to the conditions expected during both normal operation ard abnormal events within the design basis of the plant. The NRC requested that licensees respond, within six (6) months of the date of the GL, advising the NRC of the schedule for completing the recommended actions delineated in the GL Accordingly, PECO Energy Company responded to GL 89-10 for Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3, and Limerick Generating Station (LGS), Units 1 and 2, by letter dated December 28,1989. Subsequently, by letter dated March 16,1992, we submitted our program for testing MOVs at LGS and PBAPS, in which we committed to completing the testing of MOVs within five (5) years or three (3) refueling outages from the date of issuance of GL 8910, whichever is later, We are currently scheduled to complete the testing activities by the following dates: LGS Unit 1 - June 1994, Unit 2 - March 1995, PBAPS Unit 2 - November 1994, and PBAPS Unit 3 - November 1995. These dates are based on refueling schedules and are consistent with our commitment.'

PECO Energy has made a significant commitment of resources toward implementing the GL 89-10 Program at PBAPS and LGS. The purpose of this letter is to advise the NRC of the status of our actions and plans concoming the implementation of our GL 89-10 efforts, and to notify the NRC of planned changes to cur MOV testing program being implemented at PBAPS and LGS as committed to in response to GL 89-10, item 1. In addition, this letter also provides a comparison between our planned changes to the MOV testing program and the guidance specified in GL I

' 4 Prge 2 89-10, Supplement 6, "Information on Schedule and Grouping, and Staff Responses to Additional Public Comments," issued on March 8,1994. The following items discuss efforts that 1) have been taken, or are ongoing, in accordance with PECO Energy's commitments as documented in our response to GL 89-10 submitted by letters dated December 28,1989 and March 16,1992, or

2) involve the planned changes to our MOV testing program.
1. PECO Energy has developed, reviewed, and refined the scope of those MOVs that are applicable to GL 89-10 for both PBAPS and LGS. The design basis for operation of each MOV has been reviewed and docuinented. The NRC has reviewed this design bas!s information for the applicable MOVs during subsequent inspections of our GL 89-10 Program at PBAPS and LGS.
2. PECO Energy has developed MOV switch setting guidelines and implementing procedures. Switch settings for the MOVs have been established at both PBAPS and LGS through extensive in-situ testing using state-of-the-art diagnostic equipment and testing methods. All MOVs within the scope of GL 89-10 at PBAPS and LGS have previously been set up through in-situ static baseline testing. All MOVs have been or will be retested due to changes in the state-of-the-art test equipment and improved methodologies.
3. In order to appropriately focus resources needed to implement the GL 89-10 actions, PECO Energy has developed a graded approach to testing MOVs in the GL 89-10 Program. This graded approach constitutes a change to our previous commitments regarding implementation of our GL 89-10 Program for PBAPS and LGS. The graded approach includes MOV ranking based on safety significance combined with MOV grouping based on valve configuration and service condition similarity. This approach was presented to NRC representatives during a meeting held on October 19,1993.

Additionally, the grouping methodology considers the recommendations specified in Supplement 6 to GL 89-10. The results of this graded approach will be available for review upon completion.

4. An extensive program for in-situ dynamic testing of MOVs has been implemented at PBAPS and LGS With the graded approach to testing MOVs, future dynamic testing of MOVs within the GL 8910 Program will be implemented on a representative sample of safety significant MOVs that are in families containing MOVs which are practicable to test. As a result, MOVs of greater safety significance are tested on a priority commensurate with their safety significance. The samples will be at least 30% or a minimum of two (2), of the safety significant MOVs in the family. This testing maintains our high level of confidence that each MOV, regardless of its safety s'gnificance, will perform its intended function wht i subjected to the conditions that are considered  ;

during both normal operation and abnorma! events within the design basis of our plants.  !

We expect to complete this testing by the original commitment dates specified in our j responses to GL 89-10 dated December 28,1989, and March 16,1992.

I

! 5. We also plan to apply the graded approach to our periodic verification testing for MOVs l within the GL 89-10 Praani. Pr pe' iodic test intervals are being revised based on the

! safety significance of the MOVs. Jh,s maximum testing intervals for safety significant MOVs will range from two (2) to eight (8) fuel cycles. Non-safety significant MOVs will be tested on a post maintenance basis. Specific valve test intervals will be based on the maintenance and performance history as well as the safety significance of each MOV.

6. PECO Energy is actively involved in the Electric Power Research Institute (EPRI) efforts I with the MOV Performance Prodletion Program. We intend to apply the information derivod from this program, as appropriate, to maintain our confidence that all MOVs .

within the scope of GL 89-10 will perform their intended function when required. We I I

expect to complete this second stage of the "two-stage" program approach using EPRI information one year after the final EPRI MOV Performance Prediction Program methodology and results have been received, and applicable EPRI training has been completod.

Attachment I to this letter provides a list of MOVs in the PBAPS GL 89-10 Program. It includes Information regarding valve families, ranking, and dynamic testing plans. Similar Information for LGS is provided in Attachment 2. These lists, which are current as of this date, are submitted for your information and are subject to change as we proceed with the implementation of the testing program.

All valves which will not have their capability verified by in-situ dynamic testing will, as a minimum, be sot up with the best generally available industry data. Additionally, reviews of non-safety significant valves have demonstrated a high performanco margin for those valves. The basis for our confidence that these MOVs will perform their intended function will be availablo for review upon completion.

During a meeting between PECO Energy and NRC representatives on February 17,1994, the NRC specifically requested that we delay submitting any information concerning changes to our MOV testing program pending issuance of GL 89-10, Supplement 6, at which time we should provide a comparison between our planned changes to the MOV testing programs being implemented at PBAPS and LGS and the guidance stipulated in GL 89-10, Supplement 6. The NRC issued GL 89-10, Supplement 6, on March 8,1994. Therefore, in response to the NRC's request, we have provided the requestod information in Attachment 3 of this letter.

If you have any questions or require additional information, please do not hesitate to contact us.

Very truly yours,

. 0.

Attachment 3 Page 1 of 2 PECO Energy Restructured GL 89-10 Program Comparison to GL 89-10 Supplement 6 Generic Letter 89-10, Supplement 6 "INFORMATION ON SCHEDULE AND GROUPING, AND STAFF RESPONSES TO ADDITIONAL PUBLIC QUESTIONS" provides NRC staff positions on schedule for completing MOV testing and grouping of MOVs. This discussion describes how these topics are addressed in the PECO Energy GL 89-10 Program.

SCHEDULE PECO Energy committed to completing the GL 89-10 Program actions by the following dates:

Limerick Unit 1 June,1994, Limerick Unit 2 2R03 (March,1995),

Peach Bottom Unit 2 2R10 (November,1994), and Peach Bottom Unit 3 3R10 (November,1995).

No extension of these scheduled commitment dates is planned.- PECO Energy is planning to document the basis for confirming the capability of each MOV to perform its design basis function (s) by these commitment dates which, for Limerick Unit 1, is June 1994.

MOV GROUPING PECO Energy has restructured the GL 8910 Programs at Limerick and Peach Bottom to include MOV ranking according to safety significance along with the previous MOV grouping to focus our in-situ dynamic tests on safety significant MOVs. The application of MOV grouping to the GL 89-10 Programs includes the following considerations:

1) All GL 89-10 MOVs, regardless of MOV grouping, are being set up through static diagnostic testir>g based on the best available data.
2) The MOV groups are being established based on similarities in valve manufacturer, model, pressure class and size; valve service conditions including flow, temperature, pressure, and installation configuration; valve materials of construction; and seat / guide stress levels. MOV performance during static and dynamic testing is reviewed for anomalous behavior as the test results are evaluated.

t

l

. .- )

Attachment 3 Page 2 of 2 Future dynamic testing of MOVs will be implemented on representative samples I 3) of MOV families such that the MOVs of greater safety significance are tested on j a priority commensurate with their safety significance. MOV safety significance  :

includes both impact on plant risk and MOV performance margin. The  :

representative samples will be at least 30%, with a minimum of two, of the safety significant MOVs in the family. Non-safety significant MOVs will be set up with the best available data which will include, where available, plant specific dynamic test data from similar MOVs.

l

4) The meaningful results of the dynamic tests performed, including valve factor, stem friction, and rate of loading, will be applied to all MOVs in a group.
5) The methodology for application of test data from tested MOVs to the remaining MOVs within the GL 89-10 family is currently under development.

SUMMARY

Relative to NRC staff positions on schedule, PECO satisfies all guidance in that no extensions to the existing commitment dates are planned. Relative to NRC staff positions on grouping of MOVs, PECO satisfies all guidance with the exception of not performing additional dynamic testing on non-safety significant MOVs. Non-safety ,

significant MOVs will be set up with the best available data which will include, where available, plant specific dynamic test data from similar MOVs.

Relative to NRC staff positions provided in Enclosure 1 to the Supplement regarding program approach, scope, the use of PSA studies, MOV sizing and switch settings, MOV testing, periodic verification, post maintenance testing, and pressure locking &

thermal binding, PECO is meeting or exceeding NRC guidance with the following exceptions. PECO is not planning to perform dynamic testing on non safety significant MOVs. Also, PECO is planning to use static testing to perform periodic verification.

Justification for these positions is under development.

PECO Energy has restructured the GL 89-10 test programs into a graded approach including MOV grouping and consideration of MOV safety significance. The graded approach includes focusing the dynamic test program on safety significant MOVs.

The restructured approach, including justification for not dynarnically testing additional non-safety significant MOVs, has been discussed with the NRC and is considered to be a viable alternative approach. Justification for this graded approach is nearing completion.
