Essenti'al Steam Turbine Driven Auxiliary Feedwater Pump 48 Hour Endurance Test 3M-AFA-POl As required by ITEM II.E.1.1.B.2 of NUREG 0857, a

48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months endurance test was.

performed on AFA-P01 to verify the pump's ability to provide continuous operation for a 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months period.

NUREG 0857 further required a cooldown after pump operation to allow bearing temperatures to cool to within 10'F of ambient and a subsequent one hour run.

Acceptance Criteria for operability of AFA-P01 included not exceeding bearing/bearing oil temperature and bearing cap vibration limits while operating within specified environmental temperatures.

Testing was performed in accordance with 91HF-3AF01.

The 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months run commenced November 2,

1986, and continuing until November 5, 1986.

The test was initiated and terminated by manual'peration'f the Control Room handswitch.

Pump bearing/bearing oil temperatures were monitored using the Plant Monitoring System computer display of the following plant instrumentation (see attached graphs for all recorded data):

AFA-P01 Pump Outboard Bearing Temperature 200'F max 129'F AFN-TE-85 (AFT85)

AFA-P01 Pump Thrust Bearing Temperature 200'F max 138 F

Pump inboard and outboard bearing cap vibration was monitored using an IRD model 810 portable vibration analyzer and probe.

The following maximum values were observed and are compared to the upper limit (see attached graphs for all recorded data):

Non-Essential Auxiliary Feedwater Pump 48 Hour Endurance Test 3M-AFN-P01 As required by ITEM II.E.l.l.B.2 of NUREG 0857, a

48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months endurance test was performed on AFN-P01 to verify the pump's capability to provide conti'nuous operation for a 48.hour period.

NUREG 0857 further required a cooldown after pump operation to allow bearing temperatures to cool to within 10'F of ambient and a

subsequent one hour run.

Throughout this testing, bearing/bearing oil temperatures and bearing cap vibration were monitored to verify that no

,parameter exceeded'ts design limit.

Testing was performed in accordance with 91PE-3AF01.

The 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months run commenced on September 28,

1986, and continuing until October 1,

1986.

The test was initiated and terminated by manual operation of the Control Room

.pump handswitch.

Pump bearing/bearing oil temperatures were monitored using the Plant Monitoring System computer display of the following plant instrumentation (see attached graphs for all recorded data):

INSTRUMENT (PMS)

AFN-POl Pump Outboard Bearing 200'F max 129'F Pump inboard and outboard bearing cap vibration was monitored using an IRD model 810 portable vibration analyzer and probe.

The following values were observed and are compared to the upper limit (see attached graphs for all recorded data):

PARAMETER AFN-P01 Inboard Bearing Cap Vibration AFN-P01 Outboard'earing Cap Vibration LIMIT 5.0 mils 5.0 mils MAXIMUMOBSERVED VIBRATION 0.44 mils 0.58 mils A review of all data recorded during the above endurance testing shows that no upper limi,ts on bearing/bearing oil temperatures or bearing cap vibration were exceeded.
