==SUBJECT:==
Waterford SES Unit 3 Docket No. 50-382 Supplemental Information for Technical Specification Change NPF-38-16 Diesel Fire Pump Batteries

==REFERENCE:==
W3P86-2163 dated June 24, 1986

==Dear Mr. Knighton:==

By the referenced letter LP&L submitted proposed Technical Specification change request NPF-38-16 which would delete a visual inspection requirement for the diesel fire pump batteries.       In discussions with your staff concerning this change, LP&L was requested to provide the following additional information.
The batteries in question are 162 plate, 143 pound batteries with a cold cranking capacity of 1000 amp-hours and a r< serve capacity of 440 amp-hours. The present batteries are manufactured by the Red Diamond Battery Company of Hot Springs, Arkansas, and are the same type used in starting large trucks, tractors and other industrial equipment.
LP&L has attempted, through the supplier, to locate a clear case battery but has found that apparently none are available of the size and capacity necessary for the diesel fire pumps. It is our understanding that the NRC has also made a limited search with the same results. Therefore, given the unavailability of clear case batteries, a requirement to visually inspect the bottom of the battery cell plates could not be performed in any reasonable manner.
Various other controls and Technical Specification requirements are in place to ensure operability of the diesel fire pump batteries. Technical specification surveillance requirements 4.7.10.1.3.a.1 and 2 require that at least once per 7 days the electrolyte icvel and battery voltage be verified.

Page 2 W3P86-2364 August 29, 1986 least once per 92 days the specific gravity of each cell is verified (T.S.
4.7.10.1.3.b). Technical specification surveillance requirement 4.7.10.1.2.a.2 calls for the diesel fire pump to be started every 31 days to verify operability through an actual start test. In addition to the surveillance tests Waterford 3's preventive maintenance program specifies weekly starting of the diesel fire pumps and monthly specific gravity checks of the batteries; the diesel fire pump batteries are replaced on a 40 month interval. Finally, it is also worthwhile to note that each diesel' fire pump hac available two separate and redundant batteries.
Please contact Mike Meisner (504-595-2832) should you require further information on this matter.
