Sub.iect: ANO-2 Emergency Feedwater System Evaluation, gyi s
Our letter to you dated November 24, 1980 identified open areas in this review and requested additional informatoon. Since then, AP&L Co. has submitted letters dated March 16. May 8, and July 1, 1981. These letters, in addition to the AP&L Co. letter dated September 17, 1981 on TS 4.7.1.2(b), have provided information which supports resolution of a number of the items addressed in our November 24, 1980. letter. However certain matters remain unresolved.
Some of these unresolved items have been addressed innconference calls and appear near resolution pending the documentation of information. These items as well as those which continue to be unresolved are discussed in the enclosure.
We request that responses to these items be provided within 30 days of your receipt of this letter.
The information requested in this letter affects fewer than ten respondents; therefore OMB Clearance is not required under P.L.96-511.
Sincerely.
Original signed by Robert A. Clark Robert A. Clark, Chief Operating Reactors Branch #3 Division of Licensing Enclosure cc: See next page 8202080059 820115 PDR ADOCK 05000368 Ot P

ENCLOSURE RE0 VEST FOR INFORMATION AND POSITIONS-A.
Short Term Recommendations 3.
Recommendation- "TheSurheillanceRequirementssectica5ftheTech.
'nical Specifications should add' pressure and flow acceptance criteria for the periodic (31-day) testing of the motor. driven pumps." ANO-2
,s Surveillance Requirement 4.7.1.1 presently requires a 31 day test for.
the turbine driven pump to demonstrate its operability bylverificatioo. j t
of proper discharge pressure and flow. There is not presently an'equiv-alent requirement for the motor driven pump. The licensee, in its re-sponse of March 16, 1981, stated:
"TheANO-2motordrihenEFWpumpisanASMECodeClass3 pump.
It is tested, as are all safety-related pumps, in accordance with Section XI of the ASME Boiler and Pressure Vessel Code as required by 10 CFR 50.55a(g). To address your concern of the frequency of testing, AN0-2 is committed to the 1974 Edition thru the Summer of 1975 Addenda of the Code which requires the testing of the motor driven pump driven every 31 days. AP&L will continue to test the motor driven pump in'accordance with~Section XI."
The licensee's response is unacceptable. While.we agree that perform -
ance of a flow test of the motor driven pump every 31 days is an acceptable.means for verifying flow capability, our position remains that a Surveillance Requirement be included in the Technica.1 Specifications for. testing the motor driven pump every 31 days, similar to the existing Surveillance Requirement for'the turbine driven pump.
~
The licensee is requested to propose an amendment to the.ANO-2 Technical Specifications incorporating the following Surveillance requirement.
"Verifythateachmotordrihenpumpdehelopsadischargepressure of greater than or equal to 1200 psig at a flow of greater than or equal to 560 gpm."

Long Term Recoommendations a,
1.
Recomendation GL-2
~'
,.s, The licensee's response in its July 1, 1981 letter needs to b'e supplemented p
by the provision of the response time of the system in switching EFW Tamp j.'
s\\
suction from the condensate storage'and the adequacy of this responseitin
'N in. protecting the pumps from the effects of suction flow termination.
D.- New Ouestions y
1.
The' licensee's response in.its May 8, 1981 letter indicated'that the C problem of recurrence of overspeed trips during startups of the turbine I
driven EFW pump had been resolved and that a rest report would be j
forthcoming.
The licensee is requested to provide the subject report.

3.
The staff had previously understood that the EFW steam turbine,'adrMssion vhlves are. locked open with power removed during normal power. operations The, licensee is requested to confirm the present status of these valves and to. identify the procedures and/or controls governing the statas of these valves.
