Division of Reactor Safety SUMMARY t Scope: This routine, announced inspection was conducted in the area:, of Fire Protection / Preventio Results: The insoector identified the following strengths in the implementation of the licensee's fire protection program:

l -

Staffing of the fire protection group is very good. The group appears knowledgeable of fire protection issues and has adequate  ;

manpower to implement the licensee's program, l J

~

-

The licensee's management appears to be committed to the successful implementation of the fire protection program, This {

is evident based on their responsiveness to correct the single weakness identified in this report and their approval of plant administrative procedures which effectively implement the fire protection progra The licensee has effectively implemented a program of controlling the movement of transient combustible in and out of the plant which insure unsafe fire hazards will not be present, j This is evident based on the very good housekeeping in the plant, i

s .

.

The following potential weakness was identified:

- The licensee's method for 1.15pection of one and three hour fire

,

rated raceway wraps has a potential weakness. The present procedure does not identify those raceways required to be protected, instead the procedure directs the inspector to visually inspect all fire rated assemblies in a given roo Therefore, there is the potential that a fire rated wrap could be removed and not identified during the periodic inspection l since the raceways required to be wrapped are not specifically (

"

identified in the procedure. This is identified as a potential weakness because the inspector field inspected a number of required wraps and found them all to be intact. In response to this potential weakness, the licensee's management committed to revise the periodic inspection procedure to include the identification of the raceways required to be protected as identified by the Grand Gulf Fire Hazards Analysis.

,

The remaining areas of the fire protection program reviewed appear to be adequate. No deviations or violations were identified in the areas inspecte !

Protectica Association (NFPA) Fire Codes, Based on this review, it appears that the above proc *dures are satisf actory. However, the inspector did identify a potential weakness in the rethod of perforning the 19-ronth visual inspection of fire rated assemblies, Procedure 06-ME-SP64-R-004 This procedure includes the inspection of one ar.d three hour fire rated wraps applied to electrical raceways to r,eet the intent of Section III.G of 10 CFR 50 Appendix The procedure does not presently identify the specific raceways which are to be protecte Inst tac the precedare instructs the inspector is si sucily inspect all fire rated assemblies in a given room, The inspector expressed

i l concern that by not specifically identifying the raceways required to 1 be wrapped in the procedure it is possible that missing wraps may not l

! be identificd during the periodic inspection. The licensee agreed l l

with the inspector that the present inspection riethod does represent 6

Annual QA Audit QSA-SE!0003 April 22, 1980  ;

Nuclear Mutual Limited Insurance j Inspection by M&MPC Fe0ruary 29 - March 3, 1938

'

These audits identified several fire protection program discrepancies and unresolved items, anc recc~enced several progran imprc vemen t s .

The licensee has either implerested the correctise actions associated I

with these audit findings or a scheduled date for ccmpletion of tLe  ;

'

correction actions had been established. The licensee appears to be taking the appropriate corrective actions on these audit finding . Fire Brigado  ;

(1) Organi:ation l The total station fire brigade is composed of approximately 84 ,

personnel fr:m the Operations staf f, lhe on duty shif t fire ,

brigade leader is normally one of the licensed operators and the remaining four fire brigade members are composed of non-licensed operators. The inspector reviewed the on duty shifts for June  !

and July of 1983 and verified t, hat suf ficient qualified fire j brigade personnel were on duty to meet the provisions of the j plant's Technical Specification, ,

In addition, the inspector verified that sufficient personnel f wore assigned to each shift to meet the minirum ocerating and l fire brigade staf f requirements of the Technical Spec"ication [

'

Therefore, it appears based on the review of the duty rosters l associated with the above dates, that there was sufficient i

maapower on duty to reet botn the cperational and the fire brigade requirements of the plant's Technical Specification ;

i (2) Training The inspretor reviewed the training and drill records for seven  !

brigade leaders and ten brigade members for 1957 and 199 The ,

records reviewed indicated that each of these leaders and members had attended the required training and participated in ,

the required number of drills. The inspector ilso verified that {

a fire brigade drill had beer conducted every 92 days for each  !

shift for 19S7 and 19SS. The fire brigade training records l reviewed were found satisfactor In addition, the inspector reviewed the licensee's periedic fire

'

Drigade training modules. These modules cover the following areas:

Module 1 Self Contained Broatning Apparatus f Module 2 Site Specific Information  :

Module 3 Gases l Module 4 Fires In Energ?:ed Electrical Equipment r M:dule 5 71res In Cables ar.d Cable Trays j Module 6 Hydrogen Fires (

! review, it appears that the licensee's initial fire brigade training program covers the above required training topic ;

p (3) Fire Brigade Drill l p }

[ During this inspection, the inspector witnessed an unannounced '

i fire brigade dril The drill scenario was a fire in the

{ Division I Diesel Generater Roem which w3s apparently caused by a diesel fuel line break which sprayed fuel oil on the diesel ;

l engir.e and igr.ited the fuel oi l

!

Seven fire brigade members responded to the pending fire  !

'

errergency. The brigade assembled in the fresh air corridor i cutside the room in full protective firefighting turnout l

,

clothing and five brigade members wore self contained brc>athing ;

j apparatu The fire brigade leader rade an initial size-up of ;

d the fire and directed brigade rembers to advance two 1-1/2 inch l.

'

fire attack hose lines utilizing firefighting foan from the plant fire truck into the area. The fire attack hose lines were

'

placed in service on 'he fire and thc fire was placed under control within 20 minutes. Tha brigade leader also di ected f brigade rerbers to isolate the source of the fuel oil lea l

!

The fire brigade utilized proper manual firefighting r ethods and (

reacted to the fire drill scenario in a satisfactory manne I During this drill, the inspector noted that tb fire alarm broadcast over the plant PA system could not be heard in the fresh sir corridor of the Diesel Generator Buildin In discussions with fire brigade members following the drill, the inspector was told that the alarm also could not be heard in the j fire truck house. The inability to hear fire alarms announced over the PA system was also noted as a prcblen in 13 of the 35 l fire brigade dril' critiques reviewed by the inspecto Fire brigade r erbers present y carry radios which the control l r room uses to advise members of fires in the plant. However, the irspector expressed concern to the plant rnanagement that since the fire alarm tray also constitute an evacuation alarn, ,

inabtlity to hear the alarm could potentially result in people ;

being trapped by a fire. This e ncern will be followed up on in !

a faure inspectio !
