M;mng Address Alabama Power Company 600 North 13th Street Post Office Box 2641 Birmingham, Alabama 35291 Telephone 205 783-6090 R. P. Mcdonald Senior Vice President Flintridge Building Mghgg]3 gg November 27, 1985 Docket Nos. 50-348 50-364 Director, Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, D.C. 20555 Attention: Mr. L. S. Rubenstein Joseph M. Farley Nuclear Plant - Units 1 and 2 Proposed Technical Specification Change Gentlemen:

A review of the Draft Revision 5 to the Westinghouse Standard Technical Specifications identified a clarification of what methods are acceptable in performing the Quadrant Power Tilt Ratio (QPTR) surveillance requirements when an excore detector channel is inoperable. The existing Farley Nuclear Plant Technical Specification 4.2.4.2 and Action 2.d of Table 3.3-1 only allow the use of the symmetric thimble locations, while the Revision 5 Standard Technical Specification and the Farley Movable Incore Detector System Bases 3/4.3.3.2 permit a full core flux map or symmetric incore thimbles . Aiabama Power Company hereby proposes to modify the Farley i

Technical Specification 4.2.4.2 and Action 2.d of Table 3.3-1 to allow a full core flux map for verifying the indicated QPTR when one excore power range detector channel is inoperable. It is requested that this proposed Technical Specification change be approved by March 31, 1986.

Since the proposed Technical Specification change includes no changes which would significantly increase the probability or consequences of an accident previously evaluated, no changes which create the possibility of a new or different kind of accident from any accidents previously evaluated and no changes which would involve a significant reduction in a margin of safety, it is considered by Alabama Power Company to not involve a significant hazards consideration as defined in 10CFR50.92. This conclusion is based upon the change clarifying the surveillance requirement for QPTR to make it consistent with the Standard Technical Specifications and that a full core flux map provides a more accurate representation of core performance than a map developed f rom the symmetric thimble locations.

Mr. L. S. Rubenstein November 27, 1985 U. S. Nuclear Regulatory Commission Page 2 Alaban Power Company's Plant Operation Review Committee has reviewed this proposed change and the Nuclear Operations Review Board will review this propoted change at a future meeting.

Pursuant to 10CFR170.21, the required License Amendment Application Fee of $150.00 is enclosed. In accordance with 10CFR50.90, three signed originals and forty additional copies of this proposed change are enclosed.

A copy of this proposed change has also been sent to Mr. Dan Turner, the Alabama State Designee, in accordance with 10CFR50.91(b)(1).

If you have any questions, please advise.

Yours very truly, 7y ,%'
