APPENDIX B NOTICE OF DEVIATION Tennessee Valley Authority Docket Nos. 50-259, 50-260 and 50-296 Browns Ferry 1, 2 and 3 License Nos.

FSAR Section 10.11.3.1 references the April 21, 1977 TVA letter from J. E. Gilleland to E. G. Case of NRC/NRR as one of the documents containing the fire protection modification commitments made by TVA as a result of the March 22, 1975 fire.
The enclosure to this letter identified a number of plant doors to be changed to approved fire doors and doors to be upgraded to equivalent approved fire doors.
These modifications were to be completed by the end of the first refueling outage of either Unit 1 or Unit 2.
Unit I restarted from the first refueling outage on January 15, 1978.
Contrary to the above, several doors in the control bay portion of the plant, primarily on the 593 and 617 foot elevations, have not been changed to approved type fire doors.
Many cf these doors contain ventilation louvers and thus do not have a fire resistant rating.
B.
The applicable code or standard approved by the Commission for the design and installation of sprinkler systems is National Fire Protection Associ-ation Standard No. 13 (NFPA-13).
NFPA-13 Section 1-8.1.2 states that only approved materials and devices shall be used in sprinkler systems.
Contrary to the above, unapproved fire protection deluge valves are provided for the HPCI sprinkler systems.
C.
National Fire Protection Association Standard No. 80 Sections 2-8.2 and 2-8.7 require that automatic closing fire d0 ors be provided with positive i
latching hardware which automatically engages when the door moves to the closed position.

Contrary to the above, a pair of fire doors (door no. 294) is not provided with automatic latching hardware.
Provide this office within twenty-five days of the date of this Notice written comments including a description of corrective actions that have been or will be taken, corrective actions which will be taken to avoid further deviations and the date your corrective action will be completed.
