SUBJECT:
Peach Bottom Atomic Power Station, Units 2 and 3 Limerick Generating Station, Units 1 and 2 Supplemental Response to Generic Lottor 89-10
" Safety-Related Motor-Operated Valvo Testing and Survo111anco - 10 CFR 50.54 (f)"
REFERENCE:
Letter from D.
R. llelwig (PECo) to NRC, dated December 28, 1969
Dear Sir:
The referenced lotter submitted Philadelphia Electric Company's (PECo) response to Generic Letter (GL) 89-10,
" Safety-Related Motor-operated Valve Testing and Surveillance,"
wheroin PEco request.ed approximately two years to comple e its response to Item (c) of the Generic Letter.
Dao to the many uncertainties surrounding GL 89-10 issues at the time, PECo required the additional two year period to evaluate alternatives to the in-plant motor operated valve (MOV) testing requested by GL 89-10, item (c), and to develop a MOV differential pressuro and/or flow testing program.
We have completed our ovaluation of alternatives to ir.~ plant MOV testing and as a result have developed the attached " Program for Testing of Motor Operated Valvos" (Attachment 1), which will be implemented at noth Yeach Bottom.\\tomic Power Station (PBAPS),
Unita. 2 and 3 and Limerick Generating St.ation (LGS), Units 1 and l
2.
The Prograta delineates the criteria for selecting valves to i
be teated and describes the selection of test conditions.

Att achmont 2 to this letter providos a list of t.ho MOVs at PDAPS determined to be testable at design basis ditferent.lal pressure. Attachmont 2 also providos a list. of the MOVs dotormined to bo testablo at highest system attainablo difforential prosauro.
Attachmont 3 providos aimilar information for LGS.
Those lists, which are current as of this date are submittod for your information and may be subject to changos as we proceed with t.hu implomontat. ion of the Losting progran.
PEco has mado a significant commitment of resources to support the MOV Users Group and the Electric Power Roscarch Institute (EPRI) MOV Performanco Prediction Program. Tho intent of the EPRI research program is to develop methods to predict performance of MOVs.and alternativos to dosI.gn-banis testing.
The current schedulo for completion of this program in 1994.
l Upon completion of the EPRI program, it is PECo's intent to uso the information derived from it, as wol) as information from other organizations and programs, to ensure that diagnostic techniques are appropriately used to assuro operan111ty of safety related MOVs.
This submittal completeh PEco's response to GL 89-10 Item (c).
If you have any questions concerning it, or requiro additional information, please contact us.
