Dear Dr. Morris:
9s,
Subject:
Oyster Creek Station Docket No. 50-219 Diesel Fire Pump Starting Failure The purpose of this letter is to report to you the failure of Diesel Fire Pump 1-2 to start during a surveillance test on March 21, 1972.
l 1:
m This surveillance test consists of starting each pump from t
the control room and again by lovering the fire pump discharge header
. u, pressure. The pump started on the signal from the control room but
/
did not start on the drop in header pressure. The operator in
(
attendance observed that the diesel cranked very slowly.
Each fire
/'
pump is started by a starting motor driven electrically by a 24-volt DC battery. Each pump is equipped with two, 24-volt DC batteries either of which may be used for starting. Each battery is composed of two heavy-duty 12-volt batteries connected in series. The Shift Foreman on duty went to the fire pump location and by selecting the alternate battery for 1-2 pump, started the diesel although it cranked very slouly, it was determined later that each of the batteries serving the failed pump has one bad cell. The 12-volt batteries which had the baTcell were replaced with new batteries.
In the future, closer attention will be given to possible battery deterioration.
l I Il 7 We are enclosing twenty-five copies of this report.
ANf Very truly yours,
{l).
