SURVdILLANCE REQUIREMEtTS (Continued) d.- At least one'. per 18 months, during shutdown, by verifying that:

1. The battery capacity is adequate to supply a dumy load of the fAlowing profile while maintaining the battery terminal voltage greater than or equal to 105 volts.

a) During the initial 60 seconds of the test

1) Battery 2A-1 greater than or equal to 916 amperes.

2) Battery 2A-2 greater than or equal to 916 amperes.

3) Battery 2B-1 greater than or equal to 916 amperes.

4) Battery 2B-2 greater than or equal to 916 amperes.

b) During the remainder of the first 30 minutes of the test

1) Battery 2A-1 greater than or equal to 250 amperes.

2) Battery 2A-2 greater than or equal to 250 amperes.

3) -Battery 2B-1 greater than or equal to 250 amperes.

4) Battery 2B-2 greater than or equal to 250 amperes. ,
