20555 F-Attention: Mr. L. S. Rubenstein Joseph M. Farley Nuclear Plant - Units 1 and 2 Celetion 'of Rod Bow Penalty Technical Specification Change Gentlemen:

The phenomenon of fuel rod bowing is accounted for in the departure from-nucleate boiling. ratio (DNBR) safety analysis for Farley Nuclear Plant Units 1 and 2.

Westinghouse WCAP-8691,. Revision 1 has been accepted by the NRC as successfully demonstrating that applicable generic credits for margin result:ng from retained conservatism in the evaluation of DNBR and/or from imeasured plant parameters can be used to offset the effect of DNBR penalties

-due to rod bow. The Joseph M. Farley Nuclear Plant Units:1 and 2 safety analyses maintain sufficient margin'to fully offset the DNBR' effects of rod bow.--

It is therefore proposed that the rod bo.w penalty _(RBP) curre.cly included in the Farley Nuclear Plant Units 1 and 2 Technical Specifications be deleted.- This' penalty is no longer required and the deletion of this 4

penalty will result in the removal of an unnecessary restriction on plant operations. lists the changed Technical Specification pages and

. includes the proposed changed pages. 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 t,y Alabama

- Power Company to not involve a significant hazards consideration as defined in 10CFR50.92. This conclusion is based upon this change maintaining the k#8 gj 0 182 851127 P

' margin inherent in the minimum DNBR limit of 1.30 for transients which must account for fuel rod bowing in the accident analysis and this change not altering the plant configuration or modes of operation. The details 'of the 10CFR50.92 evaluation are provided in Attachment '2.

Alabama Power Company's Plant Operations Review Committee has reviewed this proposed change and the Nuclear-l'perations _ Review Board.will review this proposed change at a future meeting.

As required by 10CFR170.21, the 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).
