The purpose of this letter is to inform NRC of changes that TVA has incorporated into

the Bases section of the Units 1 and 2 TSs. Specifically, TVA has revised Bases Section 3/4.7.8 for both units to clarify the intent of the vacuum relief flow during TS required testing of the auxiliary building gas treatment system in accordance with Surveillance 4.7.8.d.3. The Unit 2 Bases Section 4.7.1.2 has also been revised to

-indicate the' current operational functions of the turbine driven auxiliary feedwater

. level control valves that were modified during the Unit 2 Cycle 6 refueling outage.

These valves have been modified to be nonmodulating and automaticelly open upon an accident signal. The Unit 1 Bases have not been revised to include this information because the modification will not be completed until the Unit 1 Cycle 7 refueling outage. The enclosure provides the revised Bases pages affected by these revisions.

Please direct questions concerning this issue to Keith Weller at (615) 843-7527.
