Fire IPEEE Tier 2 Documentation Scenario No. FA32, Revision 2 SECTION 3 A bounding fire in this compartment would involve postulated failure of the systems identified above. This fire would result in unacceptable results.
FIRE SCENARIOS Therefore, fire modeling was performed to refine the analysis as discussed below.
In the discussions below, no differentiation is made between sections of a cable tray. Therefore, if a tray is partially within the fire zone of influence, all associated trays are assumed damaged.
AFWpump FW-10 large oilfire. 1- Steam Driven AFW Pumn FW-I0 - Larue Fire A postulated 'large' auxiliary feedwater pump fire is assumed to occur with a 18% conditionalprobabilityof conditional probability of 0. 18. The fire was characterized as a spill of the entire large spill oil inventory from the pump, 5.5 gallons. This fire has the potential to damage cable trays located directly above. The FIVE Inside Plume worksheet (Attachment B, Sheet "FW-10 Large - In-Plume") was used to determine whether target damage occurs. This situation was further evaluated using the Outside Plume and Radiant Exposure worksheets (Attachment B, Sheets "FW-10 Large- Out-Plume" and "FW-10 Large - Radiant", respectively).
Unconflned spill results in high Using the FIVE methodology, an unconfined large spill involving 5.5 gallons of heat rate, but 1O secondfire oil would cover 660 sq.ft. and have a fire duration of 10 seconds. However, a credible fire event would require some time to ignite the oil spill, would involve duration not credible. a fire growth phase, then continued combustion until available fuel is depleted.
Such a fire can be expected to bum for several minutes. For the purposes of the Fire Risk Analysis, it will be conservatively assumed that the minimum credible fire duration is 2.5 minutes. This 2.5 minute assumption is based on several parameters as discussed below.
Assumedfire duration is 2.5 In order to provide realistic results, the analysis considers a confined oil spill so minutes. that the fire duration can be extended. The selection of a 2.5 minute minimum fire duration is based on the following considerations.
I. A short fire duration is conservative. However, the 10 seconds associated with an ideal unconfined spill fire is unrealistic.
- 2. The Fire PRA Implementation Guide [5] indicates that ignition of IEEE 383 qualified cables would require fire exposure for 5 to 10 minutes.
- 3. A realistic oil pool fire can be expected to experience some degree of oxygen depletion which would reduce the overall combustion rate (longer fire duration). This reduction can be modeled by considering a smaller pool surface area.
- 4. The cable damage times (Appendix G of [5]) range from 2 to 19 minutes for temperatures of 700 'F and higher.
Adjust spillsurface area to obtain Using the 2.5 minute fire duration, the resulting fire characteristics are provided in 2.5 minute durationfire. - __ Attachment-B. Sheet "FW-l0-Large-Fuel". The postulated 5.5 gallon oil spill fire has a fire intensity of 4528 Btu/s and a surface area of 45.7 sq. ft.
A number of physical parameters for the fire compartment are needed in order to assess the response of the 'nearest' target and the automatic fire suppression system. The determination of these parameters is based on the postulated oil spill originating from FW-10.

Fire IPEEE Tier 2 Documentation Scenario No. FA32, Revision 2 The fire is of sufficient magnitude that damage to targets in the fire plume will occur. Therefore, an outside of plume worksheet was used to evaluate the extent of damage to targets beyond the fire plume.
Trays 2S, 1 7S, and 18S potentially Height to Target = 14.5 feet - The nearest target above FW-10 is cable tray impacted. 2S, which is 14.5 feet above the floor. Other trays above FW-10 include the following: 18S at 15.5 feet high; and 17S at 16.5 feet high and 8 feet laterally.
Trays 3S, 4S, 5S, 6S, 19S, and 20S are also near FW-10. However, the 1-hour radiant barrier partially surrounding FW-10 prevents the oil spill from spreading in their direction and provides some measure of shielding from the radiant heat effects.
Room Height = 20 feet- FCS Fire Hazards Analysis [2].
2 Floor Dimensions = 207.8 x 27 feet - This is based on a floor area of 5,610 ft and an approximate room width of 27 feet near the pump.
Radial Distance to Targets = 7.6 feet - The postulated oil spill has a surface area of 45.7 ft2. This equates to a diameter of 7.6 feet for a circular spill. Since the spill can occur anywhere around the pump, a 7.6 foot radius around the pump is assumed for determining potential targets impacted.
Fire Intensity = 4,528 Btuls - the assumed fire intensity is based on the assumptions discussed earlier. Attachment B provides a worksheet which develops this value.
FireLocation Factor= I - the fire is assumed to be in the 'center' of the room.
Ambient Temperature = 90 'F - this assumed value is used for the maximum expected ambient temperature during normal plant operations.
Outside ofplume damage distance The outside of plume worksheet (Attachment B, Sheet "FW-10 Large - Out-Plume") predicts a radial damage distance of 4.8 feet. Therefore, if a target is
- 4.8feet.
located in the jet region, but more than 4.8 feet from the fire plume, target damage is not expected.
Radiant exposure damage distance Additionally, the radiant exposure worksheet (Attachment B, Sheet "FW-10 Large - Radiant") predicts a critical radiant flux distance of 12 feet. The only
- 12feet.
critical component within this distance is FW-6, however it is separated from FW-10 by a 1-hour radiant barrier. Therefore, no additional targets are assumed to be damaged due to radiant effects.
Thins scenario was evaluatedfurther to determine the target damage time versus suppression system actuation time. Successful actuation of the suppression system prior to the predicted target damage time would prevent such damage. The additional parameters needed for this analysis are discussed below.

Fire IPEEE Tier 2 Documentation Scenario No. FA32, Revision 2 Heielit to Taret = 11.5 feet - Although the actual target height is approximately 14.5 feet, the height used in the analysis was reduced to 11.5 feet, which is the lowest height which would yield a target damage time greater than the suppression system actuation time.
RadialDistanceto Tareet = 0.1 feet - The target is conservatively assumed to be located above the fire source.
FireLocation Factor(Target) = 1- The fire is assumed to be in the 'center' of the room.
Radiant Fraction = 0.40 - this value is based on guidance in FIVE [4].
Rated Detector Temperature = 165 0 F-this value is based on the device setpoint
[7].
Ambient Temperature = 75 'F- The assumed ambient temperature for this case is assumed to be 75 'F. This has the effect of increasing the detector response time.
Sprinklers approximately 8 feet Distance to Detector = 10 feet vertical, I foot horizontal - There are two sprinkler heads located directly above AFW pump FW-IO, approximately 8 feet abovefloor.
above the floor. Other detectors and sprinkler heads are located throughout the room. For conservatism, a vertical distance of 10 feet and a horizontal distance of 1 foot are assumed.
Fire Location Factor (Detector) = 1- the fire is assumed to be in the 'center' of the room. This provides the most conservative result with respect to detector response.
Target Location = I (in-plume) - The targets are inside the postulated fire plume.
Target Thermal Response Parameter = 34 - This represents a nominal value for XPE/XPE cables with 0.43 inch diameter [4].
Detector Time Constant = 120 - this assumed value is based on the highest (slowest) detector in the reference tables [4].
Targets greaterthan 11.5feet The results of the suppression system actuation analysis are provided in above the pump will not be Attachment B, Sheet "FW-10 Large - Suppression". Assuming a 'virtual' target 11.5 feet above the pump and inside the fire plume, the analysis conservatively damagedif suppression is predicts a cable damage time of 7 seconds and a suppression system actuation time successfuL. of 6.95 seconds. The expected damage time for the actual targets, since they are located higher than 11.5 feet, would be greater than 7 seconds.
Based on this analysis, it is concluded that successful actuation of the suppression system during a postulated large oil spill fire will limit damage in this fire' compartment such that only the pump itself will be damaged.

Fire IPEEE Tier 2 Documentation Scenario No. FA32, Revision 2 AFWpumnp FI-1W0 small oilfire. 2. Steam Driven AFW Pump FV Small Fire 82% conditionalprobabilityof A postulated 'small' auxiliary feedwater pump fire is assumed to occur with a conditional probability of 0.82. The fire was characterized as a spill of 10% of small spilL the entire oil inventory, or 0.55 gallons. This spill is assumed to occur with an 82% conditional probability [5]. The characterization of such a fire is based on the same fundamental parameters as that considered for the large oil spill fire. The resulting fire has a surface area of 4.6 sq.ft., a duration of 2.5 minutes, and an intensity of 453 Btu/s.
Targetsgreaterthan 8.3 feet above The analysis of this postulated fire was evaluated using the FIVE worksheets for thze pumip will not be damaged. the Inside Plume and Radiant exposure cases (Attachment B, Sheets "FW-10 Small - In-Plume" and "FW-10 Small - Radiant", respectively). The completed analysis worksheets are based on the same input parameters as the FW-10 large fire. The analysis shows that targets located 8.3 feet or more above the postulated fire would not be damaged.
The radiant exposure case performed using 1 Btuls/ft 2 critical flux limit yields a critical flux distance of approximately 3.8 feet. Given the 1-hour radiant shield between FW-10 and FW-6, as well as the spacing between FW-10 and the air ompressors, this heating mechanism is not a concern with respect to target damage.
Based on this analysis, a postulated small oil spill fire should be assumed to result in damage to only the pump itself.
AFWpump FWV-6 large oilfire. 3. Motor Driven AFW Pumn FW-6-Large Fire A postulated 'large' auxiliary feedwater pump fire is assumed to occur with a 18% conditionalprobabilityof conditional probability of 0.18. The fire was characterized as a spill of the entire largespill. oil inventory from the pump, 3.5 gallons. This fire has the potential to damage cable trays located directly above. The FIVE Inside Plume worksheet (Attachment B, Sheet "FW-6 Large - In-Plume") was used to determine whether target damage occurs.

A number of physical parameters for the fire compartment are needed in order to assess the response of the 'nearest' target and the automatic fire suppression system. The determination of these parameters is based on the postulated oil spill originating from FW-6.
The fire is of sufficient magnitude that damage to targets in the fire plume will occur. Therefore, an outside of plume worksheet will be used to evaluate the extent of damage to targets beyond the fire plume.
Trays 2S, 3S, 4S, 18S, and 195 Height to Target = 14.5 feet - The nearest target above FW-6 is cable tray potentially impacted. 2S, which is 14.5 feet above the floor. Other trays above FW-6 include the following: 18S at 15.5 feet high; 19S at 14.5 feet high and 8 feet laterally; 3S at 18.5 feet high and 6.5 feet laterally; and 4S at 14.5 feet high and 11.5 feet laterally.

Fire IPEEE Tier 2 Documentation Scenario No. FA32, Revision 2 Outside ofplume damage distance The outside of plume worksheet (Attachment B, Sheet "FW-6 Large - Out-
- 2.6feet. Plume") predicts a radial damage distance of 2.6 feet. Therefore, if a target is located in the jet region, but more than 2.6 feet from the fire plume, target damage is not expected.
Radiantexposure damage distance Additionally, the radiant exposure worksheet (Attachment B, Sheet "FW-6 Large
-9.6feet. - Radiant") predicts a critical radiant flux distance of 9.6 feet. The only critical component within this distance is FW-10, however it is separated from FW-6 by a 1-hour radiant barrier. Therefore, no additional targets are assumed to be damaged due to radiant effects.
This scenario was evaluated further to determine the target damage time versus suppression system actuation time. Successful actuation of the suppression system prior to the predicted target damage time would prevent such damage. The additional parameters needed for this analysis are discussed below.
Hei/ght to Target = 12.7 feet - Although the actual target height is approximately 14.5 feet, the height used in the analysis was reduced to 12.7 feet, which is the lowest height which would yield a target damage time greater than the suppression system actuation time.

In this case, with an oil inventory of 3.5 gallons, a 2 quart spill is considered more limiting. This spill is assumed to occur with an 82% conditional probability [5]. The characterization of such a fire is based on the same fundamental parameters as that considered for the large oil spill fire. The resulting fire has a surface area of 4.2 sq.ft., a duration of 2.5 minutes, and an intensity of 412 Btu/s.
Targets greaterthan 8.0 feet above The analysis of this postulated fire was evaluated using the FIVE worksheets for tihe pump will not be damaged. the Inside Plume and Radiant exposure cases (Attachment B, Sheets "FW-6 Small

The fire is of sufficient magnitude that damage to targets in the fire plume will occur. Therefore, an outside of plume worksheet will be used to evaluate the extent of damage to targets beyond the fire plume.
Trays IS, 16S, and 16S-1 Height to Target = 16.5 feet - The nearest target above the air compressors is potentially impacted. cable tray I S, which is 16.5 feet above the floor.

Radial Distance to Targets = 8.6 feet- The postulated oil spill has a surface area of 58.2 ft. This equates to a diameter of 8.6 feet for a circular spill. Since the spill can occur anywhere around the compressor, a 8.6 foot radius around the compressor is assumed for determining potential targets impacted.

This scenario was evaluated further to determine the target damage time versus suppression system actuation time. Successful actuation of the suppression system prior to the predicted target damage time would prevent such damage. The additional parameters needed for this analysis are discussed below.
Heit'ht to Tareet = 16 feet - Although the actual target height is approximately 16.5 feet, the height used in the analysis was reduced to 16 feet, which is the lowest height which would yield a target damage time greater than the suppression system actuation time.

Target Location = I (in-plume) - The targets are inside the postulated fire plume.
Tareet Thermal Response Parameter = 34 - This represents a nominal value for XPE/XPE cables with 0.43 inch diameter [4]

Assuming a 'virtual' target 16 feet above the pump and inside the fire plume, the analysis conservatively predicts damaged if suppression is a cable damage time of 16 seconds and a suppression system actuation time of 15.5 successful seconds. The expected damage time for the actual targets, since they are located higher than 16 feet, would be greater than 16 seconds.
Based on this analysis, it is concluded that successful actuation of the suppression system during a postulated large oil spill fire will limit damage in this fire compartment such that only the pump itself will be damaged.

82% conditionalprobabilityof A postulated 'small' air compressor fire is assumed to occur with a conditional probability of 0.82. The fire was characterized as a spill of 10% of the entire oil small spilL inventory, or 0.7 gallons. This spill is assumed to occur with an 82% conditional probability [5]. The characterization of such a fire is based on the same fundamental parameters as that considered for the large oil spill fire. The resulting fire has a surface area of 5.8 sq.ft., a duration of 2.5 minutes, and an intensity of 576 Btu/s.
Targets greaterthan 9.1 feet above The analysis of this postulated fire was evaluated using the FIVE worksheets for the pump will not be damaged. the Inside Plume and Radiant exposure cases (Attachment B, Sheets "IA Small -
In-Plume" and "IA Small - Radiant", respectively). The completed analysis worksheets are based on the same input parameters as the air compressor large fire.
The analysis shows that targets located 9.1 feet or more above the postulated fire would not be damaged.
The radiant exposure case performed using I Btu/s/ftW critical flux limit yields a critical flux distance of approximately 4.3 feet. Given the 8.6 foot spill radius, this radiant exposure distance is sufficient to potentially damage all three compressors.
Based on this analysis, a postulated small oil spill fire should be assumed toresult in damage to only the three compressors. I
