03/20/87 page 1 of 6 PALO VERDE NUCLEAR GENERATING STATION TEST/RETEST RECOVERY PROGRAM DIESEL GENERATOR "B" AND ASSOCIATED SUPPORT EQUIPMENT The following test/retest outline has been developed to summarize testing activities that will demonstrate the capability of Unit 3 Diesel Generator "B" and its support equipment. Additional testing beyond that which is normally required is also identified herein to demonstrate that Diesel Generator "B"'ngine repair was conducted successfully,. The following tests are scheduled to be performed.

1. COOPER ENERGY, (Initial Test)

2. 73PE-3DG01, (Mech. preop. carry over test)

3. 73PE-3PE01, (Elect. preop. carry over test) 32ST-'9PE01, (El'e'ct.,surveillance test)

1.1 Web deflection measurements will be verified and recorded prior to the initial start.

1.2 On the initial start DGB will be operated for approxi-mately 15 minutes, at no load. Continuous observation of engine operating parameters will be monitored, (i.e., temp, pressure, speed 8 vibration).

1.3 After the initial run all crankcase doors will be removed and the following performed:

1.3.1 All bearing caps (main and rod) will be inspected for unusual hot spots.

1.3.2 Visual inspection for signs of water leaks.

1.3.3 Hand check chains and tighteners.

1.3.4 General inspection of all exposed components for any signs of stress.

1.3.5 If all inspections are satisfactory, DGB will be made ready for break-in.

1.4 Break-in will require an initi'al 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> no load run followed by loading in 25X increments thru lOOX. A 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> time period will be imposed at each level of load before proceeding to the next level. All engine operating parameters will be in continuous observation and recorded on an hourly bases.

03/20/87 page 3 of 6 1.5 Interim inspection after break-in loading.

1.5.1 Check for external leaks and distress.

1.5.2 After 30 minutes following shutdown remove crankcase doors and immediately check the crankshaft web deflection per CB manual.

1.5.3 Visually check inside of crankcase for abnormalities.

1.5.4 Review logs for abnormalities, if none are found replace crankcase doors.

1.5.5 Start and gradually increase load to 100X over a two hour period.

1.5.6 Increase load to 110X and hold for two hours.

2.0 73PE-3DG01, (MECH. PREOP. CARRY OVER TEST) 2.1 During performance of this test, DGB will be tested to those test objectives required to re-establish engine control and alarm functions.

3.0 73PE-3PE01, (ELECT. PREOP. CARRY OVER TEST) 3.1 D'uring performance o'f this preoperational carry over test, DGB will 'be subjected to about 92.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> at various load configurations. 88.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> will be at 100X load with 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at 110X load. Approximately 40.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> of the 100X -load time will be required for the 35 starts.

The remaining 48.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> at 100X load will be performed after 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at 110X. Acceptance criteria for the 35 starts requires that load be 50X or greater. In this case 100X load will be maintained during each of the 35 start runs.

4.0 32ST-9PEOl, (ELECT. SURVEILLANCE TEST) 4.1 This surveillance test does not load DGB and has a short run time of about one half hour. No mechanical inspec-tions are performed on the engine. Mechanical and elect-rical measurements are taken on the generator to verify that the diesel generator and its associated electrical equipment are in an operable condition.
