Fire Protection/Prevention Program (64704)
The inspector evaluated the adequacy and implementation of the licensee's Fire Protection Program described in the Updated Final Safety Analysis Report (UFSAR) and in Station Administrative Procedure VPAP-2401, "Fire Protection Program."
In addition, a comparison was made of the program to selected NRC Safety Evaluation Reports which approved the station fire protection progra The plant is currently operating under fire protec-tion features in the plant Technical-Specifications '(TS); however; in January 1993, the licensee submitted to the NRC an amendment request to remove fire protection features from the T This request is now under review by NRC/NR *
2 Fire Protection Organization The Station Manager has overall responsibility for the fire protection progra This responsibility has been assigned to the Supervisor, Station Safety and Loss Prevention who is under the supervision of the Supervisor, Administrative Services - Nuclea The Station Safety and Loss Prevention organization includes a staff of fire protection specialists who are assigned to coordinate the implementation of the fire protection program through the Operations, Training, Maintenance, and Engineering organization An Appendix R coordinator has been assigned to the station system engineering organization onsite to assist Operations, Safety and Loss Prevention, Engineering, and the Planning Departments in maintaining compliance with Appendix R re-quirement The Station Safety and Loss Prevention organization has an effective program for inspection of plant fire prevention and protection fea-tures. Monthly fire protection inspections are conducted in some 64 safety and nonsafety-related plant areas. Reports of these inspec-tions are provided to plant managemen These reports address the status of fire prevention activities, fire protection system deficien-cies, and housekeeping conditions for all vital plant area The inspector's review of the reports of the licensee's fire protection inspections conducted in 1993 determined that these reports provided an effective management tool for monitoring the effectiveness of the site fire prevention progra Fire Protection Program Implementation The inspector reviewed the onsite fire protection program implementing procedure VPAP-2401 (Revision 1, dated April 1, 1993}, "Fire Protec-tion Program~" and compared it to the program description in the UFSAR and the fire protection T The review indicated that the fire protection program met NRC guidelines and had been updated to include a description of the current fire protection staffing organizations with their responsibilities and interfaces; Appendix R safe shutdown equipment; and policies for the operability of Appendix R fire protec-tion features currently in the fire protection T It was noted, however, that the Surry fire protection program document had not yet been updated to incorporate fire protection administrative requirements for certain NRC Branch Technical Position BTP 9.5-1 fire protection features included in Chapter 12 of the Appendix R Report and UFSAR as part*of the pre-Appendix R *licensing,*basis for Surr This issue was previously identified at North Anna Station and dis-cussed in NRC Inspection Report 50-338, 339/93-1 The licensee indi-cated that this issue was being reviewed and tracked at Surry by Station Engineering Tracking Item No. 5135 Licensee actions includ-ed initiation of a Type 1 project to verify that all fire protection commitments are properly documented and maintained through development of a list of fire protection commitments cross-referenced to the
"
- station program documents which implement each commitmen This effort is currently scheduled to be completed for Surry in September 199 This was considered a program weakness and is identi-fied as Inspector Followup Item (IF!) 280, 281/93-18-01, Followup of Licensee Actions Associated with Surry Station Engineering Tracking Item No. 5135 Fire Reports The inspector reviewed the station fire incident reports for 1990, 1991, 1992, and 199 These reports indicated that there were eleven incidents of fire in safety-related plant areas during the period 1990-1992, which required fire brigade respons No significant fires had occurred during this perio Most events were minor fires involving electrical equipment failure Thus far in 1993, there had been one reported plant fire involving a dust collection box associated with the turbine rotor cleaning proces.
Material Condition of Fire Protection Features Records of Maintenance The inspector reviewed a computer listing and description of the Work Orders (WOs) issued for repairs to plant fire protection systems for a one-year period from June 1992, and concluded that the work had been appropriately prioritized. A small number (a total of 38) impairments for repairs were recorded for the one-year perio Most of these repair impairments had been restored to service and a small backlog of work orders remained for scheduled completion. A single fire protec-tion yard main system leak had been identified and was scheduled for repair in late July 199 Based on this review, it appears that when fire protection systems are found degraded or inoperable a high priority is assigned to promptly return these systems to service. This was considered a program strengt Records of Periodic Surveillance Testing The following surveillance test procedures were reviewed to verify compliance to the requirements of VPAP-2401 and fulfillment of fire protection Technical Specification (TS) requirements, if applicabl Within the review, no discrepancies were note Periodic Test Number Title-Reference PT-2 Fire Main Flush TS 3.21. PT-24.10 Fire Hose Station TS 4.18.F. Inspection and Flow Test PT-24.12 Fire Pump Flow Rate Test TS 4.18.B. PT-24. llC PT-24.20 PT-24.50 Fire Brigade a. Organization

Normally, a compliment of five qualified brigade members are assigned to each shift. The Operations department provides three qualified personnel, including one that must be additionally qualified as a fire brigade scene leader. The Security department provides the two other team members who are qualified for the fire brigad An additional compli-ment of reserve fire brigade personnel are available from the Safety and Loss Prevention group, the Health Physics staff, and the Opera-tions staff to assist in emergency fire fighting efforts, if neede The ~nspector verified that sufficient shift personnel were available to staff each shift's fire brigade with at least five qualified fire brigade members exclusive of the minimum required shift crew specified in the T Training and Drills To evaluate fire brigade effectiveness, the drill critique data required by procedure O-LSP-FP-004 for the following drill scenarios conducted in 1991, 1992 and 1993 were reviewed by the inspector:

Based on this review, the inspector concluded that drill frequency requirements were being satisfied. Overall brigade response times and personnel participation for these drills were considered satisfactor The inspector did note however that, for the time period reviewed, brigade drills had been conducted on an infrequent basis in those plant fire areas where deviations from NRC fire protection require-ments had been approve These plant areas were evaluated by the NRC in the Supplemental Safety Evaluation Report, dated February 25, 198 The evaluation discussed four plant fire areas which do not have full area suppression in conformance with Section 111.G of Appendix R to 10 CFR 5 The evaluation concluded that, based on the existing fire protection features, the absence of an automatic suppression system throughout each area was an acceptable deviation from the NRC require-ment These existing features included low combustible loading, separation of redundant safe shutdown components, and an early warning fire detection system that would detect a fire early in its incipient stage and, by an alarm, would alert the control room operators who would dispatch the fire brigade to extinguish the fire manuall The enhancement of the fire drill program to include fire brigade drill exercises in these fire areas is identified as Inspector Followup Item 280, 281/93-18-02, Conduct of Fire Drill Exercises in Fire Areas Where Deviations from NRC Fire Protection Requirements Were Approve A fire brigade drill was conducted on July 1, 1993, at 1:30 p. m.,
which was observed by the inspecto The drill involved the observa-tion of black smoke in the Unit 1 Mechanical Equipment Room at the electrical Power Transfer Cabinet and spreading through the Unit 1 alleyway towards the control room air intake. Response to the fire drill consisted of: one Senior Reactor Operator, one Fire Scene Leader, two operations fire brigade members, two fire brigade members from Security, two Fire and First Aid employees, and two Security personnel for area control. The fire brigade responded promptly (4 minutes) in full protective clothing with appropriate fire fighting equipment, established a command post and effectively used radio communications with the control room to develop a fire attack strate-g Carbon dioxide fire extinguishers and one 1 1/2-inch fire hose line were used to combat the simulated fire. Control room personnel adequately addressed plant safe-shutdown conditions of the simulated fire event. Site Emergency Plan conditions were also properly moni-tored during the drill evolutio Following the drill, a critique was held with the participants and drill evaluators to discuss ~he good points~and items that could be improved. Overall response to the fire drill and the exercise cri-tique were considered goo Fire Fighting Strategies Fire fighting strategies (pre-fire plans) are provided for the safety-related plant areas and are contained in Operations Surry Power Station Pre-Fire Plan The following strategies were reviewed during this inspection:
Fire Strategy N, 158, 159, 160 101, 102 121, 122, 123 173 211 Plant Area Auxiliary Building, Fire Area 17 Unit 1 Cable Vault and Tunnel, Fire Area 1 Units 1 & 2 Diesel Generator Rooms, Fire Areas 6, 7, and 8 Charging Pump Service Water Pump Room, Fire Area 54 Emergency Service Water Pumphouse, Fire Area 288 The inspector walked down the above plant fire areas and verified that appropriate manual fire fighting support equipment, as specified by the fire pre-plans, were in place and functiona Based on this review, the inspector concluded that these strategies were adequate and properly addressed the fire potential, area location, means of fire brigade approach, fire protection equipment available, fire brigade action, and communications availabl. Observation of Plant Areas A general plant walkdown and inspection was performed by the inspector to verify: acceptable housekeeping; compliance with the plant's fire preven-tion procedures such as "Hot Work" permits and transient combustibles; operability of the fire detection and suppression systems; emergency lighting; and installation and operability of fire barriers, fire stop and penetration seals (fire doors, dampers, electrical penetration seals, etc.).
Within the areas observed, the inspector determined that the general housekeeping and overall compliance with the plant fire prevention procedures regarding control of ignition sources and combustible materials during plant activities were goo The majority of the wood used during maintenance activities was treated to make it fire retardan Fire retardant plastic sheeting and film materials were also being use Lubricants and oils were properly stored in approved safety container Appropriate controls for~cutting and-welding operations were being enforce Controls were being maintained for transient combustibles, and areas containing potential lubrication oil and diesel fuel leaks, such as the diesel generator rooms, were well controlled. This was considered a program strengt No major discrepancies were noted with the fire water storage tanks, fire pumps, outside fire hose houses, fire main valves or header Fire extinguishers had been inspected and had a current inspection date. The
- carbon dioxide storage tank was at the proper fill level and pressur However, the inspector noted corrosion of the exterior plant ground-level supports for the carbon dioxide control pilot piping and conduit Operability of the carbon dioxide system was not impacted by the corroded supports since other supports installed nearby on the piping and conduits were not affected by corrosion. The licensee issued Deficiency Cards No MM-93-0660 and EM-93-0492 to identify the problem and initiate corrective actions. Corrective actions in this area will be reviewed during future NRC inspection.
