The inspector evaluated the overall adequacy and implementation of the licensee's Fire Protection Program. The Hatch Fire Protection Program is described in a document entitled the Fire Hazard Analysis (FHA) which is a supplement to the Final Safety Analysis Report (FSAR). Fire Protection Organization The General Manager has overall responsibility for the fire protection program. The responsibility for implementation of the fire protection program has been assigned to Engineering Technical Support who is under the supervision of the Manager Engineering Support. Engineering Technical Support is assigned to coordinate and direct the implementation of the station's Fire Protection Progra This group also coordinates the development and maintenance of the fire protection program procedures and the FHA. Assistance in the-implementation of the program is provided by the Training, Maintenance, Operations, Security, Chemistry and Health Physics organization The Engineering Technical Support organization has an effective program for monitoring plant fire prevention and protection

correction and reinspection. The inspectors' review of the 1992 and .

1993 inspection reports on fire protection activities determined that these inspections and notices provided an effective program tool for monitoring the effectiveness and enforcement of the site l fire prevention program and was considered a strengt ! Fire Protection Program Implementation The inspector reviewed the on-site fire protection program I implementing procedure, 40AC-ENG-008-0S, Revision 5, Fire Protection Program, dated February 28, 1992, and compared it to the program .

. description in the FHA. The review indicated that the fire l protection program had been updated to include a description of the :

current fire protection staffing organizations, their responsibilities and interfaces; fire brigade membership and i training requirements handling of fire emergencies and general 'l personne! training. This effort was thorough and no discrepancies I were note The Fire Protection Equipment Impairment Log entries for 1992 and .

l 1993 were reviewed. A small number (a total of 16) of fire equipment impairments, were recorded for 1992 and 1993. .Most of j these impairments, with the exception of fire barrier assemblies i such as Kaowool fire wraps and Thermo-Lag, were restored to service l within the time-frame required by the FHA following impairment !

identification. Based on this review, it appears that when fire I protection systems are found degraded or inoperable, a high priority <

is assigned to promptly return these systems to servic ' Fire Reports  !

!

The inspector reviewed the station fire incident Deficiency Card l (DCs) reports required for procedure 10AC-MGR-004-0S, for 1992, and i 199 These reports indicated that there were five incidents of i

• fire in safety-related plant areas during 1992, which required fire i brigade response. Of these, two were minor fire events involving i cutting or welding activities associated with outages and the remainder were fires involving equipment failures. Thus far in . i 1993, there has been an overall reduction in fire incidents with i only two fires in non-safety plant areas. The low number of fires l during the past several years indicates good overall compliance with t

the plant fire prevention procedures regarding control of ignition sources and combustible materials during plant maintenance activitie This is considered a program strength.

l Fire Brigade (1) Fire Brigade Equipment Fire brigade turnout gear and equipment are stored in various ,

equipment storage areas located in strategic locations !

throughout the plant. The fire brigade equipment on the 147' #

elevation of the Control Building was inspected and found to be ,

properly stored and well maintaine !

'

During a previous inspection, the NRC inspector noted that the licensee had obtained a fire brigade equipment transport vehicle which was to be assigned solely for fire brigade us This vehicle has now been placed in service. The vehicle is designed to carry 2-1/2 inch and 1-1/2 inch fire hose, additional Self-Contained Breathing Apparatus (SCBAs) with spare cylinders, foam and foam appliances, smoke control l equipment, and miscellaneous supplies and equipmen This dedicated vehicle has provided an improvement in the movement ;

(2) Fire Drills  !

A fire brigade drill was not conducted during this inspectio I The fire brigade participated in a drill exercise conducted during a recent emergency preparedness drill which was witnessed by NRC inspectors and discussed in HRC report number 50-321,366/93-18. To evaluate overall fire brigade perfor- ,

'

mance, the drill critique data for the drill scenarios conducted in 1991, 1992 and 1993 was reviewed by the inspecto Based on this review, the overall brigade response times for these drills were considered satisfactory. Personnel partici-pation for each drill was very good (averaged 10-12 people). 4 It was noted however, that few drills were conducted-in those safe-shutdown areas which have NRC approved exemptions from Appendix R requirements. These are fire at-risk plant areas in which NRC Safety Evaluation Reports (SERs) approving the t Appendix R exemptions refer to fire brigade response to an area .

A general plant walk-down inspection was performed by the inspector '

to verify: acceptable housekeeping; compliance with the plant's fire prevention procedures such as " Hot Work" permits and transient combustibles; operability of the fire detection and suppression systems; and, installation and operability of fire barriers, fire

stop and penetration seals (fire doors, dampers, electrical penetration seals, etc.).

Within the areas inspected, the general housekeeping was l satisfactory. The housekeeping for the diesel generator rooms was very good. There was no apparent excessive leakage of lubrication oil and diesel fuel from the diesel engines and the engines and floors were apparently wiped down to remove any leaks that were present. The majority of the wood used during maintenance activities was treated to make it fire retardant. Fire retardant plastic sheeting and film materials were also being used. Lubricants and oils were properly stored in approved safety containers. No major l discrepancies were noted with the fire pumps, fire water storage tanks, outside fire hose houses, fire main valves or_ header Although there were several small oil leaks from some equipment, the leaks had been previously identified and were properly tagged and ,
