In the Matter of ) Docket Nos. 50-327 Tennessee Valley Authority ) 50-328 SEQUOYAH NUCLEAR PLANT (SQN) - TECHNICAL SPECIFICATION (TS) CHANGE 92-08,-

" BORIC ACID CONCENTRATION REDUCTION" In accordance with 10 CFR 50.90, we are enc?osing a requested amendment to Licenses DPR-77 and DPR-79 to change the TSs of SQN Units 1 and 2.

The proposed change will reduce the boric acid concentration in the boric acid tanks from 12 percent to 4 percent by weight.  ;

The proposed TS change is identified in Enclosure 1. The justification for the proposed TS change is provided in Enclosure 2. A determination of no significant hazards consideration performed pursuant to 10 CFR 50.92 ,

is provided in Enclosure 3. The technical analysis supporting the TS I

change is provided as Enclosure 4. I l

l Implementation of the reduced boron concentration for both units will not .

be accomplished until the Unit 2 Cycle 6 refueling outage that is currently scheduled to begin on September 17, 1993.. Accordingly, NRC approval of the proposed change is requested at the beginning of the Unit 2 Cycle 6 refueling outage.- A period of 60 days from the start of l the Unit 2 outage is also requested to implement the TS change.

Additionally, during this implementation period, Unit I will reduce the l boron concentration while in an operational mode. This task will be l factored into the Unit 2 restart schedule and planned to ensure that ,

power operation is not affected. Please note that the proposed TS change )

is similar to that approved for Turkey Point Nuclear Plant on July 16 -1991.
