Subject:

Change to Bases for Technical Specification 3.8.1.1,

" Electrical Power Systems - A. C. Sources" Gentlemen:

The Reference issued Amendment No.

101 to Facility Operating License No.

)

NPF-42 for Wolf Creek Generating Station (WCGS).

Amendment No. 101 revised i

Technical Specification 3/4.8.1, ' Electrical Power Systems-A. C. Sources," and its associated Bases to achieve an overall improvement in emergency diesel generator reliability and availability.

1 WCGS Technical Specification 3.8.1.1, Action b and Action c specify the required actions to be taken with inoperable A.

C.

electrical power sources.

Action b specifies the required actions to be taken within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with one inoperable diesel generator.

Action c specifies the required actions to be taken within eight hours with one inoperable diesel generator and one offsite power circuit inoperable.

Review of the Bases, issued by the Reference, has identified that the second paragraph of Bases page B 3/4 8-2 should be revised to better define the time restraints associated with Technical Specification 3.8.1.1, Actions b and c.

The verbiage, which had been revised by Wolf Creek Nuclear Operating Corporation (WCNOC) in the Bases, does not make a distinction between the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> requirements of Action b and the eight hour requirements of Action c.

WCNOC is providing the revised Bases change to reflect this difference and i

requests that the NRC issue the revised Bases page change.
