(2) The batteries were clean and appeared to be in excellent condition.

Intercell connectors were free of corrosion; vent saps were in i place on all cells. Batteries were installed in accordance with approved drawings. ,

(3) There were two cells jumpered out in each 60 cell battery, effec-tively making each one a 58-cell battery.

b. Battery Maintenance and Surveillance Program The inspector reviewed the latest revision of the battery maintenance and survei(lance procedures for San Onofre Units 2 and 3:

Procedure No. Title S023 - I - 2.12 "k'eekly Inspection of Batteries" S023 - I - 2.13 " Quarterly Inspection of Batteries" it 5023 - I - 2.14 " Refueling Interval Inspection of j Batteries 5023 - I - 2.15 " Refueling Interval Battery Service {

Test" 5023 - I - 2.16 " Battery Performance Test" l l

The procedures satisfied the requirements of Technical Specifications, j NUREG-1.129 " Maintenance, Testing and Replacement of Large Lead Storage -:

Batteries for Nuclear Power Plants", IEEE Standard 450-1980 "IEEE Recom-mended Practice for Maintenance, Testing and Replacement of Large Lead j Storage Batteries for Generating Stations and Substations", and the manu-facturer's technical instructions.

Based on this review, the inspector verified that an adequate surveillance program exists for the San Onofre Units 2 and 3 batteries

c. Surveillance Activity The inspector reviewed the schedule and records of all surveillance ac-tivity on the San Onofre, Units 2 and 3 batteries since the batteries were placed in service. The record showed that surveillances were per-formed in a satisfactory manner within the prescribed intervals. One surveillance discrepancy was identified. The 18-month surveillance procedure (5023-I-2.15) was not conducted on Unit 2 batteries 28007 and 20008 from the time the batteries were placed in service (February 1982) until it was accomplished during the current refueling outage. There-fore, for approximately one year the operability of these batteries

- was not demonstrated with respect to their ability to carry rated vital loads during an emergency. The exact durations of these failures to demonstrate operability were:

Battery 28007, from 12/6/B3 to 12/20/84 Battery 28008, from 12/7/83 to 2/27/85 J
