Fire Protection Audit The most recent audit report was reviewed.
This was Audit Report SQA8995.
Fire Protection and Loss Prevention (Annual / Triennial)
conducted August 2-11, 1989.
This audit identified a number of items requiring improvements.
These items are listed below:
Contrary to ONP-STD-5.7900, prefire plans have SQ A890450915

Fire Brigade
,
1.
Organization The station fire brigade is being reorganized.
The staff was c
formally composed of thirty full time professional fire fighters. The staff has been reduced to fifteen members. These
,
members are J. Allen, G. Camilleri, J. Carr, R. Chambers, G.
Dickey, D. Dotson, E. Hargis, J. Holdbrooks, J. Johnson. G.
.
Kelly, B. Kennedy, M. Partrick, L. Reed, G. Williams and G.
Young. The training of the above persons was reviewed and found to be acceptable.
,
!
TVA is presently replacing some of the staff with Auxiliary Unit
_
Operators.
The inspector reviewed and found acceptable the -
'
training of the following operators:
J. Andrews, T. Cooper, J.-
l-~
Headrick, J. Sparks, J. Stinson, T. Taylor,- C. Turner, E.
Varnet, E. Williams, G. Williams and M. Witt.
These members have ' been trained 'in accordance with NFPA 1001-1987, Standard l
for Fire Fighter Professional Qualifications.
!
To meet regulatory requirements, the licensee must have a
,
minimum of five trained fire fighters available during each l-shift.
The licensee's current staffing meets this requirement.
The training provided to the full time fire fighters and Auxiliary Unit Operators is in accordance with NFPA requirements and meets NRC regulatory requirements.
l 2.
Fire Brigade Drill During this inspection the inspector witnessed an unannounced fire brigade drill.
The drill scenario was smoke coming out of the north door of the cable spreading room at elevation 706.
The selection of the fire fighting equipment was appropriate for the - drill scenario.
Personnel protection equipment included Self Contained Breathing Apparatus which was worn appropriately by the fire brigade members.
Three 1-1/2 inch standpipe packs were used with a gated wye from standpipe hoselines.

and advancement of hoselines were appropriate.
Fire operetions demonstrated knowledge of standpipe operations and sector
'
leadership.
Directions to auxiliary unit operators were'appro-priate with the command post.
Use of water spray for cable trays was correct and search techniques were used appropriately.
Comunications were well established and clear.
The fire brigade leader and incident comander set up and maintained an organized fire group.
During the drill the inspector evaluated the brigade performance in the following areas:
Response time to the fire scene
-
Fire ground comand by the FBL
-
Brigade fire fighting methods
-
Fire fighting strategy
-
Comunications between the fire brigade leader and the
-
comand post.
l The brigade performance in all areas was found to be-satisfactory.
Radio comunications was identified as a corcern during an inspection
conducted November 14-18, 1988; however, it was found to be adequate i
in this drill, f.
Plant Tour and Inspection of Fire Protection Equipment-(1) Outside fire protection walkdown.
I The inspector verified the isolation valves from the fire pumps i
to the fire loop were open and-that an operable flow path existed as required by Technical Specifications.
'
The following sectional valves in the outside fire protection water supply loop were inspected and verified to be properly aligned and locked in position Valve Nos.
Location 1-26-556 1A Fire Pump Isolation Valve 1-26-558 IB Fire Pump Isolation Valve 0-26-858 Hydrant and Test Isolation Valve 0-26-860 Hydrant Isolation valve 0-26-564 Diesel Generator Building Supply Isolation Valve 02-26-1340 Yard Isolation Valve A tour of the exterior of the plant indicated that sufficient clearance was provided between permanent safety related buildings and structures and temporary buildings, trailers, and other transient combustible materials. The general housekeeping of the areas adjacent to plant structures was satisfactory.

lc (2) Permanent Plant Fire Protection Features
'A plant tour was made by the inspector.
During the plant tour the following safe shutdown related plant areas and their related fire protection features were inspected:
. Auxiliary Building Elevations; 669, 690, 714, and 734
-,
Control Building Elevations; 669, 685, 706 and 732
"
'
l Diesel Building Elevations, 722 and 750 Turbine Building Control Building Elevations; 685, 706, and 732 i
The fire / smoke detection system, manual fire fighting equipment
,
(i.e.. portable extinguishers, hose stations etc) and' the fire i
area boundary walls floors and ceiling associated for the above i
plant areas were inspected and verified to be in service or
functional.
The actomatic sprinkler system installed in the hallway outside-j the diesel generator. rooms was o)erational and the CO,' tank i
~
located in the diesel generator
)uilding was found to be 82 i
percent full at. 300 psi which satisfied Technical Specifi-
,
cations.
'
Based on this inspection, it appears that the fire protection
.;
features associated with the above fire protection areas,are d
satisfactorily maintained.
l The plant tour also verified the licensee implementation of the fire prevention administrative ' procedures.
The inspector also verified that housekeeping in the area was good.
(3) Appendix R Fire Protection Features The inspector visually inspected a sample of fire rated raceway l
barriers identified in procedure SI-233.4.
This included a visual Inspection of Thermal Fire Barriers required for i
compliance with Appendix R,Section III G in~the'following plant areas:
