FIRE PROTECTION / PREVENTION PROGRAM (64704)
This inspection was to evaluate the overall adequacy of the licensee's fire protection / prevention program and to determine that the licensee was implementing the program in conformance with regulatory requirements and industry guides and standards.
The inspector. reviewed the following STP procedures:

10/3/88 Preplans This review verified'that the licensee had technically adequate procedures to implement the fire protection program. Procedural guidance was provided to control-combustible material and reduce fire hazards. Administrative procedures also provided for maintenance and surveillances of fire suppression, detection, and support equipment. Personnel training, qualifications, and'
. responsibilities were adequately provided. Maintenance evolutions that significantly. increase fire risk were properly controlled.
The inspector toured accessible areas of Units 1 and 2 and the yard for general area conditions, work activities in progress, and visual condition of fire-protection systems and equipment. Combustible materials and flammable and
- ombustible liquid and gas usage were restricted or properly controlled in
- areas containing safety-related equipment and components.
Items checked-included-positions of selected valves, fire barrier condition, hose stations, lose houses, halon system lineups, fire lockers, and fire extinguishers for t/pe, location, and condition.
- There were no welding, cutting, or use of open flame ignition sources found in
.
~the areas toured. There was no construction activity noted inside the building e
areat toured. Some maintenance work and surveillance testing were noted.
General ^ housekeeping conditions were found to be very good. Fire brigade
equipment, including emergency breathing apparatus, was found to be properly stored and maintained.
Fire protection systems and equipment installed for protection of safety-related areas'were-found to be functional and tested in accordance with the requirements specified in the Technical Specifications. During conduct of the fire barrier penetration surveillance inspection, the licensee recently discovered that the seal material, Hydrosil, was showing signs of shrinkage and cracking. Those
penetrations were declared inoperable and a fire watch was established. The licensee has completed an evaluation and determined an effective repair. The repair configurations have been successfully tented and repairs are expected to be: completed within 2 to 3 months.
Initial determinations by the licensee indicate that this material is limited to STP use only. The licensee is still evaluating the reportability of this event in accordance with 10 CFR Part 21.

-4-The licensee informed the inspector that an engineering change notice (ECN) has been initiated to convert the halon suppression system in the Unit 2 relay room to a water suppression system. This ECN is still in the evaluation stage. The change was prompted when this halon system did not pass the initial concentration test and because of the concern over the use of halon. The vendor will not supply recharges for concentration tests. The vendor will supply recharges for accidental or fire suppression dumps.
The licensee also informed the inspector that they had exhausted all avenues of obtaining Underwriter's Laboratory approved noncollapsible fire hose and fittings. Noncollapsible hose reels are used as suppression systems in cable spreading rooms and other areas of restricted access. This was a deviation from the Final Safety Anaysis Report and fire Hazards Analysis Report (FHAR)
during the initial review and the licensee had committed to replace the nonrated hose when rated hose could be located. The nonrated hoses have been hydrotested in accordance with NFPA-196. Replacement hoses will also be qualified in accordance with NFPA-196. The licensee is proceeding with the FHAR revision.
The inspector also reviewed fire brigade training and drill records. The records were in order and confirmed that training and drills were being conducted at the specified intervals.
The last two licensee QA audits in the area of fire protection, Nuclear Assessment Audits 88-29 and 89-29 were reviewed by the inspector. The audits were comprehensive and in-depth. System / equipment alterations, tests, surveillances, maintenance, records, and overall program procedures were addressed. Discrepancies identified were formally presented to the affected organization.. Responses were tracked to closecut and actions taken were reviewed for adequacy.
There were no violations or deviations identified in this area of the inspection.
