These revisions will' resolve discrepancies between the environmental zone boundaries and the current plant configuration.

89 co4P . FA CWFoo8 DEFEAT THE CONDENSER WATER BOX PRIMING SYSTEM i

This field alteration eliminates a circulating water (CW) cystem pump start interlock, adds blank flanges on condenser water box priming line valves 1CWO18 and 1CW019 and condenser inlet water box priming valves 1CWO1MC and 1CWO1MD, and removes the internals from condenser outlet water-box priming valves 1CWO1MA~and 1CWO1MB. The CW pump start' interlock prevents the starting of the CW pumps when the condenser water boxes are not full, and thus prevents i damage to the condenser from waterhammer. This. interlock is being bypassed to allow-the water boxes to be filled by the CW pumps instead of by thervacuum priming system. To 1 minimize the potential for waterhammer in the water boxes l while they are being filled by the CW pumps, the operational methodology of the CW: system will be revised such that the L

inlet valves to the water boxes will be throttled during filling. The modifications to the condenser water box priming valves will prohibit the use of the vacuum priming system for filling the condenser water boxes and will prevent the leakage of raw lake water from the condenser L water boxes to the condenser vacuum system. l 1

available from the manufacturer. The amp-hour rating of the new cells, although different from the original cells, meets ,

, , the original design requirements of the direct current power system._ The new cells are identical in size, weight and construction to the current cells and thus there.is no impact to their seismic qualification, environmental qualification, or flame retardant cap!bility.

89 0054 'FA Hr005- CORRECT VL AND VC SYSTEM DOCUMENT DISCREPANCIES This iield alteration revises design drawings to show pressure switches and a pressure controller that are t installed in ~ the laboratory ventilation -(VL) system, and to show that valves OVC010A and OVC010B of the control room ventilation (VC) system and valves IVR002A and 1VR002B of the' containment building ventilation (VR) system are globe valves instead of gate valves. The pressure switches and the pressure' controller in the VL system provide

-overpressure protection for the VL system humidification boiler. The original startup testing of the VL system has shown that the present configuration of the-VL system, which includes the pressure switches and the pressure controller, functions as designed. Also, changing valves OVC010A, OVC010B, 1VR002A, and IVR002B from gate valves to globe t valves does not affect the design function, the performance, or the failure modes of the valves or of the VC and VR r systems.

-This-field alteration revises design documents to reflect the actual setpoint of hydrogen (HY) system excess-flow check valve 1HY687 as 5776-standard cubic fect per hour

, (scfh):instead of 1447 scfh.. The higher setpoint has a negligible impact on~the fire loading of the-turbine building and still ensures that the check valve will isolate

.the'HY: system piping in the event of.a pipe break. Also, a hydrogen leak not large enough to cause the check valve to close is unlikely because'all of the unsupervised HY system piping in the turbine building is at low pressure and is of L

welded construction.

AS A RESULT.0F THE EVALUATION, IT WAS DETERMINED THAT AN l

UNREVIEWED SAFETY QUESTION DID NOT EXIST.

88 0192 Pta 00 07 REPLACE 33 VALVES IN'THE OFF-GAS 5x8 TEM.

This plant-modification replaces 33 off-gas.(OG) system valves that have standard packing-with valves that have bellow seals. Valves with bellow seals are being installed to meet the original design criteria of the OG system, anu ,

thus. provide greater pressure boundary integrity. This q

. modification also replaces 10 quick disconnect fittings with pipe caps. As with the new valves, the pipe caps.will provide the OG' system with greater pressure boundary i integrity. The new valver and pipe caps meet the applicable piping design criteria and will not affect the operation or performance of the OG system.
