U.S. Nuclear Regulatory Commission ATTN: Document Control Desk  ;

Vashington, D. C. 20555 l Gentlemen:  !

Joseph M. Farley Nuclear Plant Proposed Change to End-of-Life Moderator Temperature Coefficient Technical Specification l The use of 18-month fuel cycles at Farley Nuclear Plant Units 1 and 2 has led to higher core average temperatures and higher discharge burnup resulting in more negative end-of-life (EOL) moderator temperature ,

coefficients (MTC). Thus, it is becoming increasingly probable that reload  ;

cores vill fail to. meet the current 300 ppm surveillance criterion ,

associated with the EOL limiting condition for operation limit.- Failure to meet the surveillance criterion does not by itself imply a failure-to meet i the actual EOL MTC limit stated in limiting condition for operation but  !

, invokes the requirement that-Hot Full Power MTC continue to be measured at- l least once per 14 Effective Full Power Days during the remainder of--the  !

( fuel cycle. This. repeated surveillance is performed to demonstrate that the actual inventory conditions for operation limit on EOL MTC is not '

i i

violated. Technical Specification 3/4.1.1.3 prescribes the limiting condition for operation and surveillance requirements for the EOL MTC. The..

existing limits contain conservatism which may result in required surveillances which place undue' demand on plant operators and require plant cperation under non-steady state conditions.

Therefore, Alabama Power Company hereby proposes to amend the Farley Nuclear Plant Units 1 and 2 Technical Specification requirements for the EOL MTC. The proposed changed-pages are provided in. Attachment 1. The ,

technical justification supporting'the proposed changes is provided in- '

l Attachment 2 as.VCAP-11953 (Proprietary) and VCAP-11954 (Non-proprietary)  !

L entitled " Safety Evaluation Supporting a More Negative EOL Moderator Temperature Coefficient Technical Specification for Joseph M. Farley Nuclear Plant Units 1 and 2."- Please note that the requested changes are very similar to those previously requested by Northeast Utilities for  !

-Millstone Unit.3 (Docket No. 50-423) by two submittals dated October 5, '

1988. The NRC approved the Millstone request by letter dated December 20, 1988.
