The METE used was a Controlotron Model fI65580 and flow data recorded was about 235 gpm during the test.

d) Vibration Data: Data was collected using a hand held vibration meter and probe. The ATE used was and IRD Model 8810. The maximum vibration limits are 5 mils and the actual vibrations recorded during the test are listed below.

Inboard Bearing: .8 1.0 mils Outboard Bearing: .9 1.2 mils e) Pump room temperature and humidity data: Data was collected using a psychrometer to measure wet and dry bulb temperatures. From this data relative humidity was also calculated.

Temperature Range: 68'F - 73'F Relative Humidity Range: 52% 82%

The 48-hour endurance run demonstrated that 2M-AFB-P01 remained within design limits with respect to bearing temperatures and vibrations. The test data also showe'd that the pump room ambient conditions (temperature, humidity) did not exceed environmental qualification limits for safety related equipment in the room, The following plots made for the bearing temperatures versus time demonstrated that the design limits . were not exceeded. Plots were also made fo'r the pump room temperature and humidity data versus time.

c) Flow Data: AFA-POl was run on minimum recirculation during the 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> run. Operations also used AFA-F01 to feed the steam generators while at the 565'F and 2250 psia test plateau.

d) Vibration Data: Data was collected using a hand held vibration meter and probe. The M&TE used was an IRD Model

/3350. The maximum vibration limits are 5 mils and the actual vibrations recorded during the test are listed below.

Inboard Bearing: .24 .46 mils Outboard Bearing: .35 .64 mils e) Pump room temperature and humidity data: Data was collected using a calibrated temperature and humidity meter (M&TE).

Temperature Range: 67.2'F to 80.5'F Humidity Range: 49.3% to 70.9/

The 48-hour endurance run demonstrated that 2M-AFA-P01 remained within design limits with respect to bearing temperatures and vibrati'on. The test data also showed that the pump room ambient conditions (temperature, humidity) did not exceed environmental qualification limits for safety related equipment in the room.
