Fire Protection at R.E.
Ginna Nuclear Power Plant Docket No. 50-244
Dear Hr. Ziemann:
In response to item 3.2.7 of the Fire Protection Safety Fvaluation dated February 14,
- 1979, we have run performance tests of the two fire pumps at Ginna Station on l1ay 16, 1979.
These tests duplicated tests run in 1969 which were used for comparison purposes.
The diesel driven fire pump showed a slight drop in pressure at the rated 2000 GPH flow.
However, the 150/ flow rate indicated a loss of pressure that was excessive.
The electric driven fire pump showed a consistently higher drop in pressure at the various flow rates than the diesel driven fire pump.
The rated capacity was within acceptable tolerances but it is approaching the limit.
We are in the process of analyzing our test methods and instrumentation to insure optimum conformance to prior tests.
Additional tests will be run if we feel there were any errors in instrumentation or methods in the liay tests.
Both pumps continue to meet the design requirements as Plant Technical Specifications.
However, if the Hay or any
- upheld, then because of the loss of pressure which has been will pull each of these
- pumps, one at a time They will be maintained as necessary, and reset.
This work will be done of the manufacturer's representative.
established in the subsequent test is experienced, we
- cleaned, inspected, under the direction Upon completion of this work, additional testing will be completed utiliz-ing the installed orifice gage to ensure that the pumps meet acceptable flow and pressure rates.
Very truly yours,
~~,p L.D. White, Jr.
