DIESEL GENERATOR STARTING AIR COMPRESSOR SUR'VEILLANCE PROCEDURE 6.3.12.2 OPEPARILITY I. PURPOSE -

A. To provide a detailed instruction for station personnel to check r

operability and reliability of the ., diesel generator starting air compressors to recharge the air receivers. -

  • II. DISCUSSION
  • A. The primary purpose of this test is to ensure that starting air com-pressors will operate to maintain approximately 245 psig in the air receivers to enable the diesels to start or restart as soon as possible.

IV. PREREQUISITES A. Ensure that the diesel generator to be tested is in the standby condi-tion according to System Operating Procedure 2.2.20.

B. Check the oil levels on air compressors 1 and 2.

C. Check the belt tension on the air compressor belts.

D. Check the crankcase oil level on the diesel driven air compressor.

V. LIMITATIONS A. Surveillance Requirements - Technical Specifications Section 4.9.A.2.a.

1. During the monthly generator test the diesel generator starting air compressor shall be checked for operation and its ability to recharge the air receivers monthly.

B. Administrative Limits.

1. All discrepancies shall be recorded in the Shif t Supervisor's log.
2. Attachment "A" shall be used 'to record the test and filed as part of the station records.
3. All testing shall be coordinated with the Control Room Operator. ,

VI. PRECAUTIONS A. Use normal precautions when operating rotating equipment.

B. When running the diesel driven air compressor ensure that the electric air compressor breaker is open.

VII. TEST EQUIPMENT A. None. '

I. PROCEDURE

A. Diesel Generator Starting Air. Compressor Operability.

1. Ensure that the diesel generator, 1 or 2, is in the standby condi-tion according to System Operating Procedure 2.2.20.
2. Display the proper indication of,the safety system status panel.
3. Verify that the air compressor selector switch is in 1.
4. Open the drain valve on the north air receiver until the air compressor IA (2A) starts at approximately 220 psig.
5. Close the drain valve that was opened in Step 4.
6. Let air compressor IA (2A) run until air receivet pressure is up to approximately 245 psig. The air compressor should stop automatic-ally. -
7. Place the control switch for air compressor IA (2A) to 0FF.
8. Open the drain valvo on the north air receiver until air compressor 1B (2B) starts at approximately 220 psig.
9. Close the drain valve that was opened in Step 8.
10. Let air compressor IB (28) run until air receiver pressure is up to approximately 245 psig. The air compressor should stop automatic-ally.
11. Place the control switch for air compressor IA (2A) to AUTO.
12. Place the air compressor selector switch to 2.
13. Open the drain valve on the south air receiver until air compressor 1B (2B) starts at approximately 220 psig.
14. Close the drain valve that was opened in Step 13.
15. Let air compressor 1B (2B) run until air receiver pressure is up to approximately 245 psig. The air compressor,should stop automatic-ally.
16. Open the breaker for sir compressor 1A (2A) and turn the control switch for air compressor IB (2B) to 0FF.
17. Open the drain valve on either receiver until the pressure is 200 psig. -
18. Verify that local alarm STARTING AIR PRESSURE LOW.
