Test Procedure l2-T'JP-4030-SP.017 was prepared to satisfy the intent and requirements
';~f the subject recommendation and con-tains detailed instr'uctions for testing the East and West Motor Driven Pumps and the Turbine Driven Pumps.
J The pumps were started on Emergency Leak off (ELO) Flow and then the
,Test Line Valves'ere opened and Test Line Flow was established.
The water supply for the pumps was the respective Unit's Condensate Storage Tank., The Steam Generator Supply Valves (FHO-211-241 for the TDAFP, FH0-212, 242 for the West MDAFP, an'd FM0-222, 232 for the East MDAFP) were'closed for the pump runs.
The water was then recycled back to the Condensate Storage Tanks.'he pumps were run on Test Line Flow for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after, the bearing temperatures had stabilized.

1 Th H t Driven Auxiliary Feed Pumps (MDAFP) &ere run a". approximately 450 The-flow rates for the MDAFP were measured using permanently installe e oor i
d,orifice plates and flow meters.
The HDAFPs were operated at the'r rated speed.
The pumps attained this speed immediately ant maintained it for the duration of the test.
Initially a General Radio Strobatac tachometer was used for th f't pump tested (Unit 2 East MDAFP).
- However, due to instrument drift this tachometer was replaced with a digistrobe tachometer which was use e ir u
d fol the remainder of the testing.
Discharge and suction pressures were also measured and recorded'hrough-out the test.
Technical Specifications for the HDAFP specify a discharge pressure of >1375 psig on ELO flow.
Prior to establi'shment of test line flow, all HDAFP's were run on ELO. flow and the discharge pressure was measured and recorded.
The discharge pressure on ELO flow ranged between 1~40 and 1455 psig.
Instrumentation used to measure tl suction and discharge pressure consisted of Ashcroft Pressure Gauges.
The total head for each of the HDAFP's was calculated using the average suction and discharge
- pressure, flow, and speed for those points having a 450 gpm flow.
These points were plotted on the respective pump curves..
The suction pressure, discharge
- pressure, speed,
- flow, and condensate water, temperature were recorded.
Instrumentation used to measure these values is listed on the Test I'nstrument List for each individual HCAFP.

I The pump driver for the MDAFP is a Reliance Ei~ctric Co. motor.
According to their operating design limits; the motor be'.rings should not exceed 185oF.
The motor bearings for each MDAFP remain<'.d wel.l below this limit for the entire test.
Motor bearing temperatures were measured at the lower portioi, of the bearing using a contact pyrometer.
t,l"I The Turbine Driven Auxiliary Fee.l Pumps (TDAFP) were operated at a flow of approximately 700 gpm.'nstrumentation for flow measurement for the TDAFP consisted of per'manently installed orifice plates and a Barton Flow Gauge in Unit 1 and a Barton DP Test Gauge in Unit 2.
)he TDAFPs were operated at their rated speed of 4350 RPM.
The pumps attained this speed immediately and maintained it for the dura.iion of the test.
Pump/turbine speed was measured using a'Digistrobe Tachometer.
The turbines for the TDAFP's were powered by main steam while the Units were at full power.
steam Pressure for Unit 1
was 770 psig (steam temp. of 516oF) and for Unit 2 was 820 psig (520oF).."-
Main steam pressure was taken from the Control Room indicators.
Suction and discharge pressures were also measured and recorded through-out the test.
Aschroft. Pressure Gaug,s were used ', measure these pressures.
The, Tcchnical Specifications for the TDAFP specify a discharge pressure > 1285 psig at a flow of ~700 gpm using steam 0 310 psig.
A flows of 700 "gpm discharge pressures were 0 1300 psig for both TDAFP's.
Total head for both pumps was calculated using an average value for speed, suctipn pressure and discharge
,pressure for all poi its with a flow of 700 + 5 gpm.
.These values are plotted on the appropriate pump curves.
The,i>uction pressure, discharge.o'essure,
- speed, flow, steam pressure and temperature, and condensate water temperature
'ere also recorded for both TDAFP's.. Test instrumentation used to measure these values is documented on the Test Instrumentation List'of each TDAFP.
The Steam Turbines for, the TDAFP are manufactured by the Terry Steam Turbine Co.
According to their literature the turbine bearing oil tempera-tures should be maintained between 110oF and 180oF.
The turbine bearing temperatures were measured on the side of the bearirg housing using a contac't pyrometer.
The turbine bearing temperatures were within the recommended.
range.
Bearing temperatures, both inboard and outboard for each pump were also measured and recorded through the'est.
According to the pumps'anufacturer, Ingersoll-Rand, the maximum temperature design limit for the bearing oil tempera-ture is 160oF.
For our test, the bee,"ing temperatures at the lower part of the bearing housing were measur d using a contact pyrometer.
All pump bear'.ig temperatures remained below 160o for the duration of the entire test.
" Plots of bearing temperature vs. time are also included.

I L
Vibration data for, each pump/driver was measured and recorded through-out the test.
The maximum allowable vibrat'on for the MDAFP is 1.8 mils and for the TDAFP 1.5 mils.
These limits were not exceeded during the test periods.
Vibration data were measured using an 'IRD Mechanalysis Model 306 Vibration Probe.

3 Pump room environmental conditions were also i,ionitnred throughout the test.
Room temperature was measured by an Alnor Pyrnmeter, dew point by an EGIIG Dew Point Hygrometer, and relative humidi ty witn a Beckman Hygrometer.
Envi ronmenta conditions were recorded and this data is ~iso plotted vs. time.
For each pu,op room, the environmental condi tions were within their design limits and did not exceed the qualification rhquirepents for the safety related equipment in the room; This equipmeni; functioned a'~,, designed throughout endurance test duration which further demonstrates it's performance capability during sustained pump operatior.
