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.
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 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.
