ATTACHMENT i
k PVORT AUDIT OPEN ITEM 1.c SERVICE WATER PUMP (AD-502) INSTRUMENTATION Presently, the Service Water Pumps use pressure indication downstream of the cyclone separators to detect impending
-failure.
A loss of pressure in the cooling water supply line results in a control room alarm, and automatic initiation of.a backup water. supply which provides cooling water to the bearings for approximately 30 minutes.
This alternative
. water supply.provides the operator sufficient time to eval-uate the problem and take the pump out of service if necessary.
Although not necessary for safety, supplemental instrumen-tation is being provided.
Temperature measurement is being added to the gland to assure the pump is operating normally.
l A high temperature indication for any reason will alarm in the control room, and the operator will manually shut the pump down.
This supplemental instrumentation will be installed prior to fuel load.
The addition of this temperature switch, in conjunction with the existing pressure instrumentation, will provide supple-(
mental detection of Service Water Pump Cooling Water problems.
