Re: Turkey Point Unit 4Docket No. 50-251Special Report — Standby Feedwater PumpsA and B Pum s Out of Service Due to Valve Re air
Both non-safety grade standby feedwater pumps were madeinoperable in order to establish a boundary to allow therepair of a common valve. In accordance with TechnicalSpecifications 3.7.1.6 and 6.9.2, the attached Special Reportprovides details of the event.
Should there be any questions on this information pleasecontact us.
Very truly yours,

SPECIAL REPORT
BOTH STANDBY FEEDWATER PUMPS UNAVAILABLETO UNIT 4
PURPOSE
Technical Specification 3.7.1.6.b.2 requires thesubmission of a special report to the NRC if both standbyfeedwater pumps are inoperable'he Technical Specifi-cation requires the report to describe the cause of theinoperability, the actions taken and the schedule forrestoration.
Back round:
Turkey. Point Nuclear has two non-safety grade standby feedwaterpumps installed to supply feedwater to either the Unit 3 or Unit 4steam generators, if needed. During the Unit 4 startup afterrefueling, valve 4-20-130, the upstream isolation valve for themain feedwater regulating valve bypass line, was found to needrepair. ~ This valve is the inlet isolation valve for flow controlvalve 4-479-. , To isolate valve 4-20-130, a ,boundary must beestablished around the valve such that no water would be allowedinto the repair zone during the work process. The establishment ofthis boundary required the isolation of not only the normalfeedwater path to the steam generators, but also the standbyfeedwater path, as well. Normal auxiliary feed water paths weremaintained and used during the repair evolution. Unit 4 wasmaintained in Mode 2 during the repair process. Unit 3 was notaffected by this isolation and remained at 100% rated power withstandby feedwater available.
EVENTS
At 0130 on May 25, 1993, plant personnel established a boundary toallow the repair of valve 4-20-130. This resulted in the isolationof the non-safety grade standby feedwater pumps from. Unit 4. Theboundary was lifted and the flow path availability using thestandby feedwater pumps was reestablished on May 25, 1993, at 1945.The total time during which both the A and B standby feedwaterpumps were not available to Unit 4 was 18 hours and 15 minutes.Notification to the NRC was made at 1045 on May 25, 1993, inaccordance with Technical Specification 3.7.1.6.b.1.

CAUSE AND ACTIONS TAKEN:
The cause of both pumps being out of service simultaneously, asdiscussed above, was the repair of valve 4 20 130, the upstreamisolation valve for the main feedwater regulating valve bypassline. Valve 4-20-130, and the standby feed water to Unit 4, wereisolated..at 0130 on May 25, 1993 for repair of the valve.
SCHEDULE FORRESTORATION'he
standby feedwater system supply to Unit 4 was returned toservice after repair of the valve at 1945 on May 25, 1993.

3. ORIGINATORREQUESTS COPY OF CLOSED CONDITIONREPORT
3,7. l. 6 Two standby feedwater pumps shall be OPERABLE" and at least 60,000gallons of water ('vailable volume), shall be in the Demineralized WaterStorage Tank"".
APPLICABILITY: MODES 1, 2 and 3
ACTION:
With one standby feedwater pump inoperable, restore the inoperable pumpsto available status within 30 days or submit a SPECIAL REPORT per 3..7. l. 6d.
With both standby feedwater pumps inoperable.
1. Within 24 hours, notify -,the NRC and provide cause for inoperabilityand plans to restore pump(s) to OPERABLE status and,
2. Submit a SPECIAL REPORT per 3.7.1.6d.
d.
With less than 60,000 gallons of water in the Demineralized Water StorageTank restore the available volume to at least 60,000 gallons within 24hours or submit a SPECIAL REPORT per 3.7. 1.6d.
If a SPECIAL REPORT is required per the above specifications submit areport describing the cause of the inoperability, action taken and aschedule for restoration within 30 days in accordance with 6'.9.2.
SURVEILLANCE RE UIREMENTS
4.7. 1.6. 1 The Demineralized Water Storage tank water volume shall be deter-s>ned to be within limits at least once per 24 hours.
:-4.7.1.6.2 At least monthly verify the standby feedwater pumps 'are OPERABLE bytesting in recirculation on a STAGGERED TEST BASIS.
7 1.6.3 At least once per 18 months, verify operability of the respectivestandby feedwater pump by powering from the non-safety grade diesel generators
,, ~~4 providing feedwater to the steam generators.
These pumps do not require plant safety 'related emergency power sources forooerability and the flowpath is normally isolated.The Oemineralized Water Storage Tank is non-safety grade.
