SR 3.8.6.6 NOTE--------------------

This Surveillance shall not be performed in MODE 1, 2, or 3 for the Division 1 and 2 125 V DC batteries. However, credit may be taken for unplanned events that satisfy this SR.

Verify battery capacity is > 80% of the 60 months manufacturer's rating for the 125 V batteries and > 83.4% of the manufacturer's AND rating for the 250 V battery, when subjected to a performance discharge test 12 months when or a modified performance discharge test. battery shows degradation or has reached 85%

of expected life with capacity < 100%

Columbia Generating Station 3.8.6-5 Amendment No. 204

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.12 Primary Containment Leakage Rate Testing Program (continued) shall be performed no later than July 20, 2009, and compensation for flow meter inaccuracies in excess of those specified in ANSI/ANS 56.8-1994 will be accomplished by increasing the actual instrument reading by the amount of the. full scale inaccuracy when assessing the effect of local leak rates against the criteria established in Specification 5.5.12.a.

The peak calculated primary containment internal pressure for the design basis loss of coolant accident, Pa, is 38 psig.

The maximum allowable primary containment leakage rate, La, at Pa, shall be 0.5% of primary containment air weight per day.

Leakage rate acceptance criteria are:

a. Primary containment leakage rate acceptance criterion is

< 1.0 La. During the first unit startup following testing in accordance with this program, the leakage rate acceptance criteria are < 0.60 La for the Type B and Type C tests (except for main steam isolation valves) and < 0.75 La for Type A tests;

b. Primary containment air lock testing acceptance criteria are:

1) Overall primary containment air lock leakage rate is

< 0.05 La when tested at > Pa; and

2) For each door, leakage rate is < 0.025 La when pressurized to > 10 psig.

The provisions of SR 3.0.3 are applicable to the Primary Containment Leakage Rate Testing Program.

5.5.13 Battery Monitoring and Maintenance Program This Program, provides for restoration and maintenance, which includes the following:

a. Actions to restore battery cells with float voltage < 2.13 V; and (continued)

b. Actions to equalize and test battery cells that had. been discovered with electrolyte level below the top of the plates: and

c. Actions to verify that the remaining cells are > 2.07 V when.

a cell or cells have been found to be < 2.13 V.
