TABLE 1 D/G VALID TEST AND FAILURE EVALUATION CRITERIA Valid tests and failures (per Regulatory Guide 1.108, Section C.2.e and Technical Specification 4.8.1.1.3) shall be based on 1
the following criteria:
1.
All s~ art attempts (automatic, including those from bona fide signals, or manual) that result in a failure to start, 1
except as noted in (2) below, should be considered valid tests and failures.
2.
Unsuccessful start :nd load attempts that can definitely be attributed to operating error, to spurious operation of a trip that is bypasssd in the emergency operating mode, to malfunction of equiptent that is not operative in the emergency operating mode (e.g., synchronizing circuitry) or,
is not part of the defined Diesel Generator unit design should not be considered yalid tests or failures.
3.
Successful starts, including those initiated by bona fide signals, followed by successful loading (sequential or manual) to at least 50% of continuous rating and continued O
operation for at least one hour should be considered valid successful tests.
(Failures occurring after one hour are not considered valid failures.)
4.
Successful starts that are terminated intentionally without loading, as defined in (3) above, should not be considered valid tests or failures.
5.
Successful starts followed by an unsuccessful loading attempt should be considered valid tests and failures, except as noted in (2) above.
6.
Testa that are terminated intentionally before completion as defined in (3) above because of an alarmed abnormal condition that would ultimately have resulted in Diesel Generator damage or failure should be considered valid tests and failures.
7.
Tests performed in the process of troubleshooting should not be considered valid tests.
Tests that are performed to verify correction of the problem should be considered valid tests and successes or failures, as appropriate.
8.
Cranking and venting procedures that lead to the discovery of conditions (e.g., excessive water or oil in a cylinder) that would have resulted in the failure of the Diesel O
Generator unit during test or during response to a bona fide signal should be considered a valid test and failure, mm

t, 2.1.7 The emergency Diesel Generators shall not be used for peaking service.
2.1.8 If the Diesel Generator is being ope. rated in the Parallel mode never transfer the LOCAL-REMOTE Switch 1-HS-4516 (4517) on PDG1-(PDG3) to LOCAL as this will take governor and voltage regulator out of the droop mode.
2.1.9 When the Diesel Generator is paralleled to the offsite power grid the kVAR load should be maintained OUT and less than one half of the kilowatt load.
2.1.10 The Diesel Generators should not be operated in parallel with the offsite grid for. prolonged periods of time.
This is to keep disturbances in the grid from affecting the Diesel Generators.
2.1.11 Only one Diesel Generator should be operated at a time except during emergency conditions.
2.2 LIMITATIONS 2.2.1 A Diesel Generator will not accept an Emergency Start signal from the Control Room if any of the following f~h conditions exist:
'd a.

VEGP 13145-1 20 29 of 43 TABLE 1 D/G VALID TEST AND FAILURE EVALUATION CRITERIA Valid tests and failures (per Regulatory Guide 1.108, Section C.2.e and Technical Specification 4.8.1.1.3) shall be based on the following criteria:
1.
All start attempts (automatic, including those from bona fide signals, or manual) that result in a failure te start, except as noted in (2) below, should be considered valid tests and failures.
2.
Unsuccessful start and load attempts that can definitely be attributed to operating error, to spurious operation of a trip that is bypassed in the emergency operating mode, to malfunction of equipment that is not operative in the emergency operating mode-(ie.g., synchronizing circuitry) or is not part of the defined Diesel Generator unit design should not be considered valid tests or failures.
3.
Successful starts, including those initiated by bona fide signals, followed by successful loading (sequential or manuel) to at least 50% of continuous rating and continued O
operation for at least one hour should be considered valid successful tests.
(Failures occurring after one hour are not considered valid failures.)
4.
Successful starts that are terminated intentionally without loading, as defined in (3) above, should not be considered valid tests or failures.
5.
Successful starts followed by an unsuccessful loading attempt should be considered valid tests and failures, except as noted:in (2) at e: 4 6.
Tests that are terminated irr'.ntionally before completion as defined in (3) above becau e of an alarmed abnormal condition that would ultimately-have resulted in Diesel Generator damage or failure should be considered valid tests and failures.
7.
Tests performed in the process of troubleshooting should not be considered valid tests.
Tests that are performed to vecify correction of the problem should be considered valid tests and successes or failures, as appropriate.
8.
Cranking and venting pr.cedures that lead to the discovery of conditions (e.g., excessive water or oil in a cylinder).
O that would have resulted in the failure of the Diesel Generator unit during test or during response to a bona fide signal should be considered a valid test and failure.
