' Revision to Unit 2 Steam Generator Tube Voltane-Based Renair Criteria Data Report Ladies and Gentlemen:
By letter dated August 7,1998, SNC transmitted the Farley Unit 21998 Voltage-Based Repair Criteria 90 Day Report. Since that time, the evaluated current cycle (13) length has been increased 72 days. As a result of this increase, the steam generator EOC steam line break (SLB) tube leak rate and burst probabilities were recalculated. The SLB tube leak rate increased from 2.0 to 2.2 gpm and the burst probability increased from 5.6x10" to 7.7x10". These results continue to be within the acceptance limits of 11.8 gpm and 1.0x102, If you have any questions, please advise. This letter contains no conunitments.
Respectfully submitted,
