to HRDenton, NRC KG&E, Inservice Testing Program for Pumps and Valves Subj:
Dear Mr. Denton:
The Referenced letter transmitted in Revision 2 to the Wolf Creek Inservice Testing (IST) Program for Pumps Generating Station (WCGS)
Transmitted herewith is Revision 4 of the Wolf Creek and Valves.
IST Program for Pumps and Valves.
The revision contains several program enhancements, corrects minor discrepancies and documents three additional relief requests (PR-10, identified during initial program implementation.
PR-ll and VR-8)
The specific changes, along with the basis for each change, are listed in Attachment 1 for Revision 3 and in Attachment 2 for Revision 4.
Revision bars have been added to designate the changes for both Revision 3 and Revision 4 to aid in your review.
The program continues to meet the requironents of Section XI of the ASME Boiler and Pressure Vessel Code,1980 Edition through Winter 1981 Addenda and provides an effective, improved program which will assure Therefore, KG&E has implemented overall safe operation of the plant.
Revision 4 pending formal NRC acceptance of an IST Program for WCGS.
This submittal is hereby incorporated into the Wolf Creek Generating Station, Unit 1, Docket.
Yours very truly, h

BASIS FOR CHANGE: Piping and Instrumentation Diagrams were renumbered to indicate site specific.
ITEM 2:
CHANGE:
Change step 2.1.4 to read as follows:
The allowable ranges specified in Table IWP-3100-2 will be used for differential pressure, flow and vibration measure-ments with the following exceptions. The Acceptable Range (on the high side) for differential pressure (DP) and flow (Q) shall be 1.05 times the reference value. The Alert Range (High Values) shall be >1.05 times the reference c,
value for differential pressure and flow. Also for DP and Q the Required Action Range (High Values) will not be used.
Should a measured test quantity fall outside the allowable range, the possibility of defining an expanded allowable range, in accordance with ASME Code interpretation XI-1-79-19, will be investigated.
BASIS FOR CHANGE: ASME Code allowable ranges specified in Table IWP-3100-2 are too restrictive (see Relief Request PR-11).
ITEM 3:

The original test frequency shall be resumed upon completion of corrective action. Also, for
.A 6 in, nominal pipe size valves, if tests show a leakage rate increasing with time and a projection based on three or more tests indicates that the leakage rate of the next scheduled test will exceed the maximum permissible leakage rate by greater than 10%, corrective action will be taken.
BASIS FOR CHANGE: To conform to corrective action per IWV-3427.
