Fire Prevention / Administrative Control Procedures The inspector reviewed the following Fire Prevention / Administrative
.
Procedures:
FPP-001, Rev. 5, Firefighting Equipment February 4, 1986
~
FPP-003, Rev. 5 Control of Transient Combustibles.
November 12, 1984 FPP-005, Rev. 7, Burn Permit January 2, 1985 FPP-009, Rev. 3, Periodic Fire Inspection March 26, 1984 SAP-131, Rev. 1, Fire Protection Program Plan April 2, 1984 Based on this review, it appears that the above procedures meet the NRC guidelines of the document entitled " Nuclear Plant Fire Protection Functional Responsibilities.
Administrative Controls, and Quality Assurance" dated June 1977; 10 CFR 50 Appendix R - Fire Protection Programs for Nuclear Power Facilities; and the licensee's Fire Protec-tion Evaluation Report except for Procedure FPP-003.
Procedure FPP-003, Control of Transient Con.bustibles, paragraph 2.2.4, 2.2.5, and 2.2.6 set the transient fire load limits associated with plant maintenance and modification activities.
However, these fire load limits are defined in total BTU which could be generated by a fire which consumed the transient combustibles associated with the given maintenance or modification work activity.
The stated low fire load limit in procedure is one million BTU, medium fire load is less than four million BTU and the high fire load is greater than four million BTU.
These fire load ranges, especially the low range could be, depending on the work area configuration, considered to be a medium /
high fire load when compared to the NFPA guidance provided in the Fire
-
.
Protection Handbook.
Therefore, in order to determine the potential fire severity these fire load ranges should be evaluated against the NFPA guidance and the fire load ranges placed in the context of BTV/FT2 of floor area being occupied by the maintenance or modifications work area.
This is identified as Inspector Followup Item (395/86-10-01),
Transient Fire Load Calculation and Does Not Follow Industry Fire Protection Practices.
.
In addition, the review of procedure FPP-003 identified that plastic combustible materials which are use in maintenance and modification work activities were not being incorporate into the transient fire load calculations.
Attachment I to FPP-003 lists various combustible materials utilized in maintenance and modification related activities.
This attachment also identifies acceptable quantities of the specified materials within the various fire loading ranges.
However, the
+
attachment does not address plastics.
This is identified as Inspector Followup Item (395/86-10-02), Plastic Materials Are Not Properly Evaluated-With, Regard To Transient Combustible Control.

Fire Protection Audit The most recent audit reports of the Summer Fire Protection Program were reviewed. These audits were:
(1) Annual Fire Protection / Prevention Program audit conducted
.
August 5-8, 1985 by Professional loss Control
'
(2) SCE&G/QA Type II Surveillance Audit Report, No. II-4-86-J conduct
!
ed February 18 through March 6, 1986.
(3) Triannual Fire Protection / Prevention Program Audit conducted August 8-10, 1983, by Professional loss Control.
These audits identified several fire protection program discrepancies and unresolved items, and recommended several program improvements.
The licensee has either implemented the corrective actions associated with these audit findings or a scheduled date for completion of the correction actions had been established.
The licensee appears to be taking the appropriate corrective actions on these audit findings, e.
Fire Brigade (1) Organization The total station fire brigade is composed of approximately 54 personnel from the operations staff.
The on duty shift fire brigade leader is normally one of the reactor operators and the remaining four fire brigade members are composed of reactor and nonlicensed operators.
The inspector reviewed the monthly operat-ing schedule for the following dates and verified that sufficient qualified fire brigade personnel were on duty to meet the provi-sions of Technical Specification 6.2.2:
April 13, 1986 April 14, 1986 April 15,1986

.
In addition, the inspector verified that sufficient personnel were assigned to each shift to meet the minimum operating and fire brigade staff requirements of the Technical Specifications.
Therefore, it appears based on the review of the monthly operating schedule associated with the above dates, that there was suffi-cient manpower on duty to meet both the operational and the fire brigade requirements of the plant's Technical Specifications.
(2) Training The inspector reviewed the training and drill records for three brigade leaders and six brigade members for the calendar year 1984 and 1985.
The records reviewed indicated that each of these leaders and members had received an annual medical review, attended the required training and participated into the required nursber of drills. The inspector also verified that a fire brigade drill had been conducted within 90 days for each for the 1984 and 1985
calendar year.
The fire brigade training records which were inspected were found satisfactory.
In addition to the fire brigade training program, the licensee is in the process of improving the performance of their site fire protection staff by developing a fire protection training manual for the site fire protection technicians. This manual covers the following topics:
History of fire protection
-
Fire behavior
-
Principals of fire extinguishment
-
Flammable liquids
-
Automatic supprejsion systems
-
Hydraulics
-
Interpretation of sprinkler drawings
-
Fire detection system
-
Centrifugal fire pumps
-
Fire hose streams and appliances
-
Inspection practices
-
The inspector made a preliminary review of this program and it appears that this manual is designed to give the site fire protec-tion technicians an basic understanding of accepted industry fire protection practices along with a basic understanding of the fire codes which are applicable to suppression and detection system design.
Therefore, upon completion of the subject training program, the site fire protection technicians should have an increased knowledge of operational fire protection issues which affect plant performanc.
(3) The inspector performed an inspection of the fire brigade equipment, consisting of fire hose, nozzles, tools, and miscellaneous equipment stored at the fire brigade equipment response locations located in the Turbine building on elevation 436' and in the Control Building on elevation 412'.
A total of 16 sets of turnout gear (coats, boots, helmets etc.),
10 sets of self contained breathing apparatus, and 20. spare air
'
cylinders are stored at the fvre brigade equipment responses locations.
Based on this inspection, the designated fire brigade equipment appeared to be properly maintained and stored in a ready condition.
(4) Fire Brigade Drill
'
During this inspection, the inspector witnessed an announced fir brigade drill.
The drill fire scenario was a fire in the Service Building Mechanical Equipment Room which was apparently caused by malfunction in the HVAC Unit.
Five fire brigade members responded to the pending fire emergency. The brigade assembled outside the Service Building near the outside entrance into the equipment room in full protective fire fighting turnout clothing and self con-tained breathing apparatus.
An initial size-up of the fire condition was made by the fire brigade leader and two 11 inch fire attach hose lines from Hose House 6 were advanced into the the Mechanical Equipment room. The fire attack hose lines were placed in service on the fire and the fire was placed under control in 25 minutes.
In addition, the fire brigade initiated fire victim search and rescue, smoke control, and water control operations.
The fire brigade utilized proper manual firefighting methods and reacted to the fire drill scenario in an effective and efficient manner.
f.
Plant Tour (1) General Plant Protection A plant tour was made by the inspector of the General Plant Fire Protection.
During the plant tour the following safe shutdown related plant areas and their related fire protection features were inspected:

-
The inspector visually inspected the fire / smoke detection capabil-ities, the manual fire fighting equipment (i.e., portable extin-guishers, hose stations, etc.) and the fire barrier walls associated with the above plant areas.
In addition, the inspector visually inspected the sprinkler protection associated with cable spreading rooms, diesel generator rooms, and service water pump house rooms.
Based on the visual inspection, it appears that the fire protection features associated with the above plant areas were properly maintained and fully functional.
The plant tour also verified the licensee's implementation of the fire prevention administrative procedures. The control of combus-tibles and flammable materials, liquids and gases and the general-
.
housekeeping was found to be satisfactory in the areas inspected.
(2) Outside Protection A plant tour was made by the inspector of the outside fire protec-tion. During the walkdown of the fire water yard loop the follow-ing post-indicator type loop sectionalizing valves and hydrant hose house were inspected:
Valve 4015-FS Valve 4014-FS Valve 4019-FS Valve 4005-FS Valve 4017-FS Hydrant Hose House 1 Hydrant Hose House 15 The above post indicator valves were found to be in the correct locked open position and the hydrant hose houses were properly equipped with the appropriate manual fire fighting equipment.
In addition, the inspector visually inspected the diesel engine and electric motor driven fire pumps and found them to be fully functional and properly maintained.
(3) Appendix R Fire Protection Features (a) Fire Barriers A plant tour was made by the inspector of various Appendix R fire area barrier boundaries.

Fire Area TB-1 - Turbine Driven Auxiliary Feedwater Pumps Fire Area TB-14 - Control Room Evacuation Panel Area
.
Based on the visual inspection of the penetration seals, fire doors, and fire dampers installed in the fife barriers associated with the above fire areas, it appears that the fire barriers assemblies inspected were fully functional and properly maintained.
(b) Raceway Fire Barriers The inspector visually inspected the following Appendix. R Raceway Fire Barrier Assemblies:
ESM 171B XX 3115B VLC 448 Based on the visual inspection of these raceway fire barri-ers, it appears that these barriers were fully functional and that their fire resistive integrity is being properly maintained.
(c)
Fixed Fire Suppression Systems The inspector visually inspected the automatic sprinkler systems protecting the following safe shutdown related plant areas:
Intermediate Building Elevation 412'-0"
-
HVAC Water Chiller Pump Room
-
