. o Duke Power Company Catawba Nuclear Station Report Number:
SD 413-414/82-27 Report Date:. January 26, 1983 Facility: Catawba Nuclear Station, Units 1 and 2 Identification of Deficiency:
The nickel cadmium batteries which are used for starting the diesel generators have developed cracks in the cell containers which could allow electrolyte leakage. The. deficiency was identified December 23, 1982.
Initial Report:
On December 30, 1982, Mr. John Rogge of the NRC, Region II, Atlanta, Georgia office was notified of this deficiency by Mr. W. O. Henry, Mr. J. D. Heffner, Mr. J. L. Crenshaw and Mr. T. J. Al-Hussaini of Duke Power Company, Charlotte, North Carolina 28242.
l Supplier and/or Component:
Transamerica Delaval, Inc. of Oakland,-California, supplied the batteries as part of the diesel generator package. The batteries were manufactured by Nife, Inc. of Lincoln, Rhode Island.
Description of Deficiency:
The units 1 and 2 diesel generator batteries at the Catawba Nuclear Station contain a total of 368 cells. Out of this total, 153 were found to have cracked cell containers (jars).
The deficiency was discovered while investigating a ground fault indication on the D.C. system.
Cracked cell containers allow electrolyte leakage which will cause a loss of stored capacity. The quantity of cracked cells in three of the battery banks is sufficient to cause battery failure. Battery failure will prevent the diesel from starting.
Analysis of Safety Implication:
The diesel generators are required to start and be ready for load acceptance within 11 seconds upon loss of all of fsite power. Battery failure would prevent the stett e y; of the diesel generator.
.. _.~
.. Corrective Action:
The actual cause of the cracking and corrective action is unresolved at this time. A sample of the damaged cells (5 cells) has been returned to Nife, Inc.
for their investigation. Nife will evaluate what caused the problem. Also, Nife will suggest the action to be taken to resolve and prevent the problem from recurring.
Resolution, corrective action and a final report are expected to be complete I
by June 1, 1983.
