In the Matter of Tennessee Valley Authority Docket No. 50-260
.the walls separating the battery, battery board and DC equipment rooms for each Unit (Fire Areas 17, 18 and
- 19) from the control building (Fire Area 16) do not appear to meet the required fire rating.
These walls are 20 gauge sheet metal panels with a resin-impregnated kraft paper honeycomb core that has been covered. with 5/8" fire code type gypsum board on each side of the panels.
The combustible core'of these panels reduces the fire resistance rating of the panels to an unacceptable level.
TVA has agreed to install additional layers of gypsum wall board on the corridor side of the wall panels.
This modification would increase the fire resistance rating of these walls.
The NRC inspection team determined that this modification would be acceptable.
Because of the lo<< fuel loading, existing detection and existing suppression in the affected
- areas, the inspection team also determined that the actual physical modification would not have to be completed until the end of the next refueling outage for Unit 2.
TVA will, however, be required to commit to modification of the existing walls, and to propose additional compensatory measu'res to be maintained until the modification is completed.
The formal commitment to modify the wall and proposal of compensatory measures will be required before unit 2 restart.
This item is identified as Unresolved Item 50-259/89-28-01, 50-260/89-28-01 and 50-296/89-28-01."

BROHNS FERRY NUCLEAR PLANT (BFN)
COMMITMENT TO REPLACE FIRE HALL This letter will satisfy unresolved item 50-259/89-28-01, 50-260/89-28-01, and 50-296/89-28-01 as identified in NRC Inspection Report 50-259/89-28, 50-260/89-28, 50-296/89-28.
NRC Inspection Report 89-28 stated:
This situation was identified to NRC in telephone calls to NRC prior to the inspection.
TVA has evaluated this situation and has determined it will be advantageous to implement the modification before restart rather than use compensatory measures.
TVA will add additional layers of gypsum wall board on the corridor side of the wall panels prior to restart of Unit 2.
This modification will achieve a
one hour fire rating for the wall which will provide adequate compartmentation in accordance with the BFN Fire Hazards Analysis.
The completion of this mcdification will satisfy the unresolved item contained in NRC Inspection Repo~ t 89-28.
Tne comi itment contained in this letter is listed in the enclosure.
