g () - II. 6SSESSIN9_EIBE_DEygLgPgggI The types of fixed combustible materials found in a nuclear power plant which can burn in such a way ps to present a significant fire exposure to the general area in which they are located are very few. The prevalent materials encountered in plant areas to be analyzed are cable insulation Jacketing and lubricating oil. The insulation and 3acketing on the cabling-in cable traps are susceptible to ignition from
-internal or external sources. The heat output from a cable tray fire will effect the atmosphere of the room in which it is located. Lubricating oil,.present in large pumps and certain other types of. plant equipment, can escape and burn.
Other types of combustibles contained within substantial metal (' b enclosures (e.g. cabling in conduit and charcoal in filter units) have been assumed not to contribute to fires. The methodology for essessing fire development can be divided into three different parts: lim'its on fire oe[elopment, fire modeling techniques, and local heating effects. Each part will-be examined in turn. 1 O . 2'
O b- III. LIMITS _QN_EIBE_DgygLgpMENT In this section, practical limitations which govern the combustion process in a room are discussed. This will g include physical limitations on the combustion of any fuel and fire test data regarding the burning characteristics of cable trays and combustible liquids such as lube oil. A. yentilation_ Limited _Eires One of the best understood and most extensively tested modes of combustion is that of ventilation controlled fires. In this type of fire, the rate of burning is limited by the fire-induced air flow into the room. s A balance is set up at each opening into the enclosure t ! where heated gases flow out the top of the opening and clean air feeds in through the bottom. The boundary layer'between the inflowing and outflowing gases is referred to as the neutral plane. Meny relationships, both empirical and analytical, have been developed to predict velocity profiles and mass flow-rates at openings during ventilation controlled fires as well as resultant heat release rates and peak fire temperatures. This analysis employs a relationship developed by Coulbert(1) which predicts the heat release rate than can be supported by the fire induced air flow. D (V _ 3
i The relation is: 0 = 1580 Ac,VH o Where Q = heat output (kW) A,= area of opening (m2) H ,= height of opening' (m) The term A is often called the ventilation factor. Any empirical relationship for'the heat release rate or 9 mass burning rate will be proportional to the ventilation factor. If there is more than one ventilation opening, then the ventilation factor is'taken as the sum of the individual ventilation factors. 4 v' The rate of burning la independent of the type of com-bustibles which are burning. The fire duration, until room burnout, is the total heat value (heat of combustion times quantity) of all the combustibles in the room divided by the heat release rate of the fire. 4 + For the purpose of this analysis, the ventilation rates were_ based on the available air-flow through openings into the room such as doorways. Fixed ventilation' cystems were assumed.-'not to contribute to the ventilation rate, since installed fire dampers will actuate. 1 a d 4
~
O . kj i B. Fuel _ Controlled __ Fires When excess air is available for combustion, the heat output of the fire will be dependent on the free burning characteristics of the exposed combustibles. The fixed combustibles that can pose a threat of damage to the structural steel in the areas where they are located consist of grouped electrical cables (cable trays) and - combustible Igquids such as lubricating oils.
- 1. Cgble_Trgy_ Burning _Chgrggteristigs The best available data on free burning cable trays containing hypalon and neoprene Jacketed cables
~g appear in the FMRC/EPRI (2) test reports. For these \'-) cables, a mass burning rate of 6.7 Kg/ min was measured for an array of 12 cable trays, each 8' long and 18** wide. This reduces to a surface controlled burning rate of O.1 (Ib/ min)/sq.ft. of cable tray or a heat release rate of 1,000 (BTU / min.)/sq.ft.
(190 KW/m 2) . Another perameter vital to cable tray fire assess-I ment is flame spread rate. Full scale tests conducted by FMRC/EPRI demonstrate a lateral spread rate of six to seven feet per hour in horizontal
. tray stacks. This figure agrees with observations of
(~}
\_/
fire' spread rates in similar tray arrays in the Reactor Building at the Browns Ferry fire. For this 5
^\
i fg k_) .t e i l analysis a more conservative figure of 10 ft/hr has ; been assumed. An important parameter that is developed fer plant areas where cable fires are to be analyzed is the average combustible loading in the cable trays. This figure is expressed as pounds of insulation and 3acketing per_ square foot of cable tray surface area. It should not be confused with the combustible load-ing per square foot of floor area, which is not used in this analysis. The combustible loading figure for the trays can be. divided by the mass burning rate O g of 0.1 (1bs/ min)/sq.ft. to determine the-time it takes for a tray to burn to completion.
~
These parameters were applied to determine the worst case fire involving cable trays that can occur in an area. The fire is assumed to originate at the point in the room intersected by the maximum number of cable trays. The-fire is assOmed to spread out along horicontal trays at.a rate of 10 feet per hour and instantaneously up any vertical trays i encountered. The area of_ cable tray which has become involved when the original point of-the fire burns itself out defines the steady state fire size. This
)
quantity is multiplied by 1,000 (BTU / min)/sq.ft. (190JkW/m*) to determine'the maximum heat release s

( rate possible from a spreading cable fire in _he area. t The duration of the spreading cable fire is taken to be the time required to consume all of the cabling in the area or 3 hours, whichever comes first. The maximum heat release rate is assumed to be the heat output of the fire through its entire duration. This 4 is a very conservative assumption since the quantity of cabling involved.will be less as the fire spreads out of the area of origin. The assumptions governing spreading cable fire scenarios hold as long as the room gas temperature remains below the ignition temp-(~)) N( erature of the cabling. The piloted ignition I , temperature used for the purposes of the peach Bottom Analysis was 900 F. If the area temperature exceeds 900 F, it must be assumed that all cables are burning simultaneously unless the fire becomes ventilation controlled.
- 2. Lubtiggtigg_Qil_Byggigg_9hggggterAg11cq Free burning fires involving combustible liquids-have been evaluated as pool fires. Although it is possible to have a' spray fire if the oil escapes through a small orifice under pressure, it would be
[) necessary to have.a high. spill rate to produce a
%)
significant. heat output. In this case the mass of 7
~ o the oil will fall to floor level and form a pool.
Pool fires of varying sizes have been studied exten-sively for many years. Hydrocarbon liquids have been found to burn such that the depth of a pool will be reduced at a rate of approximately 5 mm/ min (3). An equilibrium pool size can be calculated where the spill rate into the pool equals the mass burning rate of the fire. The consequent heat output can be determined by multiplying the mass burning rate times the heat of combustion of the liquid. The normal quantity of combustible liquids in an area k' / is that amount conteined within equipment. To accomodate the possibility that a fire could occur where the lubricants are being changed, all lubricat-ing oil quantities have been doubled in the calcula-tions. Under free burning conditions a variety of oil leakage rates and consequent fire durations and heat outputs are possible. 8 u - _ _ .
.Av (') , Iv. EIgg_ggggLIUg_IggMNIg!!gg The methodology for analyzing the fire resistance of struc-tural steel in a given plant area requires that assessments ( be made of fire duration and heat output for the fire scenarios to be evaluated using the considerations discussed previously. This information is used along with data on the materials and geometry for the compartment under considera-tion as input for a simple and conservatively realistic fire 9 model which predicts a gas temperature for the area. This-model should not be confused with sophisticated models which attempt to predict temperature profiles and/or gas concentrations throughout the room from ignition of the fire n f' through its decay period. Since the heat output of the fire has been assumed constant throughout its duration and the only parameter of interest is room area temperature, the modeling has been greatly simplified. Eggt_ggIgggg_Ugthgd Writing a heat balance for the compartment is one of the most straightforward methods of determining the area temperature of a fire, especially when the heat output of the fire is assumed constant. A simplification of the method proposed by Babrauskas and Williamson (4) as modified by Berry (5) is used. Two conservative assumptions are made which allow
~3- this simplication: )
- 1. Radiative and convective heat losses through openings 9-
! V7) in the,2nclosure are negligible (see Berry 5).
- 2. Heat loss through the walls will be dominated by the of the barriers, K (assumption of thermal inertiaslab semi-infinite approximation /)DC p.
The nessive reinforced concrete and concrete block construc-tion prevalent throughout nuclear power plants plays a very important role in determining the time-temperature history of compartment fires. The thermal penetration time of a wall or ceiling / floor slab is defined as the period of time required for a temperature rise on one side to be transferred through to the back side. The thermal penetration time is a material property and can be determined if the thermal diffusivity of the wall material and its thickness are known. l The thermal penetration time for 12-inch thick concrete walla will exceed 7 hours and for 8 inch thick concrete block walls will be approximately 4 hours. Both of these times exceed the maximum 3-hour duration for the fire scenarios analyzed
'in this study. These results have an important implication.
4 For all of the fire scenarios analyzed, the barriers will be absorbing heat without transferring it out the back face. This permits the use of the semi-infinite slab approximation for heat transfer through the walls. 4 i O t 10 ?

fire. This is not an iterative process. The formula can be used to determine the gas temperature at any time during the course of the fire. A conservative assumption that has -been made in the applica-tion of.the model is that no heat will be lost through the " ~ floor. 9 O

6 i k/ I V. LOCAL HEATING EFFECTS The fire models just discussed are used to determine gener-t alized conditions in the enclosure where the fire is occurring. However, plumes of heated gases will rise above burning obJ ects and create localized hot zones that can effect the steel'mem-bers located above. In these analyses, the results of heating of structural members due to engulfment in fire plumes has ' been referred to as localized heating effects. 9 i , .The problem of localized heating can best be quantified by applying fire plume models to predict gas Temperature profiles. The same approach can be applied to the evaluation of the b['N impact of transient combustibles on structural steel and on cable ignition. A. Plume _Modeling Alpert and Ward (8) present empirical relationships for temperature increase, A T, with r_espect to height above fuel package, H, and size of fire, O. This general relationship is as follows: OT= 3OO(kQi H Using this relationship, " safe" separation distances from fuel packages can be evaluated for localized heating of
. r. teel. If these relations predict a plume temperature at g-) the level.of the bottom flange of the steel higher than
~
the critical temperature of the steel, the heating.of the t steel is assessed. i i 1 12 _ l __

_- 1. Cable _ Tray _ Fires Cable tray fire test data was examined to establish tempenature profiles above burning cable trays. Tests performed by Sandia Laboratories (7) and FMRC/EPRI (2) o show that temperatures in the vicinity of 1500 F are reached in the flame region immediately above the surface of a burning cable tray. This temperature drops rapidly with increasing distance above the surface of the cable tray. The plume of a cable fire is dependent on the number of trays in a stack and the separation between trays. To evaluate the effects of cable trays on localized n( heating of steel, the heat release rate from a stack of trays must be estimated and used to calculate plume temperature profiles. During FMRC/EPRI (2) large scale tests on hypalon cable, the temperature measured by thermocouples 6'-5" above the top tray of the 12 trey array (2 stacks of 6) was 840 F. Using this data and applying the plume relationship described above, a temperature profile can be estimated as follows: T= 1100 F H = 5.41 ft. 1300 F 4.87 ft. 1500 F 4.45 ft. y_) Applying the plume relationships to other cable arrays is necessary to estimate the plume effects of other 13
h I 4 O'- stacks of trays on overhead structural steel. This was done by using the ratio of heat release rates
'which are directly probortioned to the width and number of trays in a stack. Estimated separation distance from stacks of 24" wide cable trays to reach plume
, temperatures of 1300 F and 1100 F are shown below: No. of Trays Distance above top tray for Tg Tg = 13OO F Tg = 1100 F i 1 2.0 ft. 2.21 ft. . 2 2.7 ft. 2.98 ft. 3 3.1 ft. 3.40 ft. i 4 3.5 ft. 3.86 ft. ! 5 3.8 ft. 4.20 ft. 6 4.1 ft. 4.50 ft. Similar separation criteria can be developed for cable a

h' i (. These criteria were used to identify areas where stacks of cable trays'were located less-than these " safe" separa-tion distances from structural steel. Thesel areas were then evaluated regarding the cable loading, size of steel member, and number of trays to determine the potential effects on the structural steel. Cable trays located within one foot of the bottom of steel beams were assumed.to sub J ect the beam to a constant temp-0 i erature of 1500 F for the period of time it takes the tray - to. burn to completion (average cable tray combustible loeding divided by mass burning rate for tray fires). Trays closer than the separation distances previously 9 identified but greater than 1 foot were assumed to subject o the beam to a constant temperature of 1300 F for the period of time it takes for the tray to burn to completion. Hori=ontal separation distances are also dependent on dis-tance from the ceiling. The ceiling jet associated with_ the impingement of the plume of the ceiling will be fairly uniform in temperature for a distance of. 2H;(0.2 x dis-tance between tray and ceiling) (8). Therefore, for cable trays in beam pockets the same separation criteria was used'for horizontal separation as outlined above for verti-cal separation.. 15

^6 5 b(J O. pgg1_Eigeg Realistic relations for determining temperature distrihu-tions for fire plumes have been developed by Heskested of FMRC (9). These relationships are based on large scale fire tests involving a variety of liquid fuela.
Fire plumes are considered to have a virtual origin (point sources) from which the plume can be considered to emanate. A virtual origin has no physical meaning for fires involv-ing most types of solid and liquid fuels. For liquid pool fires the virtual origin height, Ho, (relative to floor level) can be theoretically predicted using the following relation: Ho= -1.02D + 0.0830' Where D = pool diameter (m) Heskested gives a relation which can be used to determine the temperature rise in the plume (above. ambient) at any height in the plume. This equation is used to determine the temperature to which the structural steel located above the pool will be subjected. m . 'h1 r4 - 1' L1. 2

This evaluation included both the effects on area calculations using the heat balance ' -method a$d on localized heating from plumes. Since it is difficult and subjective to quantify the type and amount of
~
transient combustibles which could be in an area, the approach taken was to quantify the size of fire which would cause the acceptance criteria outlined in Section VII to be exceeded. ( A. 6rga_ Effects The evaluation of transient combustibles using the heat j balance method falls into three (3) categories. The first is fires controlled by ventilation openings (see Section III). For this case, transients could affect the duration of the fire but would not effect the heat 1 release rate. The heat value in BTU's of the total quan-tity of transients can be calculated by determining the extended duration necessary to exceed the acceptance j- criteria and multiplying this extended duration by the J ventilation limited heat release rete. [')h The second category.is those transients accounted for in the early stages of a cable fire ~by assuming a constant 17
~%
g ji heat release rate at the maximum value. This quantity can be estimated assuming a geometric growth of the fire. An example is shown graphically in Figure 1. The third category is the additive effects of transients combustibles on in-situ combustibles. These effects were analy=ed by applying the heat balance method for different unitized heat release rates (heat release rate from fire divided by 1.he heat loss area, Q/A.) 1; to cal-culate the duration of fires required to exceed the area temperature acceptance criteria of 1100'F. These results are plotted in Figure 2. This figure is used to deter-fs mine the maximum fires that did not exceed the acceptance (_) criteria. ( As can be seen, this does not provide a unique solution since fire size and duration provides an infinite number of combinations. For analysis purposes, only-the t maximum size fire for the duration calculated in the 1 area calculation was listed. b* BEE 011EEd.[((gg$a The hazards of transient combustibles may be either that r of an ignation source for insatu corbustibles (.i.e., I , cables) or as a direct exposure to structural steel.

Figure 3 showp the relationship of fire size to height above fuel array for these temperature criteria. The approach taken in this analysis *was to quantify the size fire in Btu /sec necessary to reach plume temperature at the bottom flange of the steel of 1100 F, 13OO'F, and For plume temperature of 13OO'F 1500 F using Figure 3. and 1500 F, the time required to heat the steel exposed to the plume to 1100 F is calculated. The heat release rate and duration yield the total BTUs which can be related to the total amount of transient combustible 1
# material.
It is important to remember that the hggt rgiggae rgte is the driving force and not the total heat of combustion of the materials. Alpert and Ward (8) provide some data on heat release rates for various materials such as wooden pallets, flammable liquids and storage related commodi-ties. Limited data exists on " trash" or health physics supplies. To develop some guidance for these commodities, Sandia Laboratories tests for ignition source fire char-acterization (12) were evaluated. The temperature profiles recorded during these tests were used to estimate maximum heat release rates for Tests 3, 4, 5

'r' Conservatiams The following conservative aanumptions were usod in thin I evaluation.
- 1. No convective heat losses through openings: Although combustion air is allowed in, no heat losses via combustion gas leaving the compartment are allowed.
- 2. No radiation heat losses through openings.
- 3. No heat losses through the floor: In calculating heat losa area, the floor area is ignored.
- 4. High cable Jacket heat of combustion: The heat of combustion of 10,000 Btu /lb was used for the hypalon JacWeted cable and was applied to mas,a burning ratos developed from large scale fires.
- 5. High heat release rates for fuel controlled fires: The heat release rate from a apreading cable fire la conservatively high based on the high fire apread rate of 10 ft/hr, the high heat release rate per unit area of tray (from 4), the selection of
'gg the origin in the area where trays are most dense, and using
( ,e the maximum heat release rate throughout the fire duration.
- 6. Localized heat of steel: Localized heating of the steel l assumes exposure of the entire exposed surface area to the plume and temperature at the bottom flange, regardless of the beam depth and ignores conductive heat losses down the length of the beam.

- 1. 6BE6_QEgg81Ellgy The area under consideration is the Torus Area on the 92' 6** and 116' elevations of the Unit 2 Reactor Building (Fire Area Sc). The bounding walls are constructed of reinforced concrete with an average thickness of 3.5 ft. - (see Attachment A for a sketch of the area under consideration. The surface area of the walls and ceiling is 43,306 sq. ft.
2- 995BMEIIBLE_Lg6plyg This area contains cable trays. The average loading in
} the cable trays is 4.3 lbs/sq. ft. of cable tray surface area. .The heaviest concentration of cabling found within this area was located on the east side of the room. The total surface area of cable trays in this area is 114 sq.

There are four doors which enter this area. One personnel door enters this area from each of the corner rooms. Each of the doors measure 3 ft. wide by 5'-10" 1 high.
- 4. coggg_gg651ggg A spreading cable fire was assumed to originate in the area of heaviest cable concentration in order to present the' worst case. The fire is assumed to start at a point source and spread horicontally along the cable trays in f
each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 7.2 feet in each direction (} along the cable trays before the original point source dies out after 43 minutes. A maximum surface area of 18.4 sq.ft. of cable trays (see Attachment B for a list of trays) will be involved at any one time, which is 9 equivalent' to a heat output of 323 kw. This heat output is assumed constant throught the fire duration. The r
-actual heat output as the fire spreads out of the area originally involved would be less since the quantity of 4
cabling involved at any one time would be less. t 4 M ()

() The case examined was that of a spreading cable fire occurring when one personnel door was open. The fire duration was taken to be 180 minutes which is the maximum fire resistance rating required for the barrier and the maximum temperature reached was 107 F which is below the critical temperature for the structural steel (see Attachment C for results of analysis.) Since the resulting fire was fuel controlled with one door open, it will also be fuel controlled if any additional doors are open. The cable trays in this area were positioned such that they did not present a localized heating exposure to the structural steel.
- 6. EEEE9If 9E IBeE!IEEI 90MBMEIIBLES The worst case fire examined was fuel-controlled with a duration of 180 minutes. The maximum additional heat i

- 1. SBgo_Dgg9BIEII9E The area under consideration is the North Vacuum Breaker Room on the 116' elevation of the Unit 2 Reactor Building (Fire Area SG). The bounding walls are constructed of reinforced concrete with an average thickness of 3 ft. -
(see Attachment A for a sketch of the area under consid-eration). The surface area of the walls and ceiling is , 2,813 sq. ft.
- 2. ggggggIIgLg_LgepIgg This area contains cable trays. The average loading in the cable trays is 4.96 lbs/ sq. ft of cable tray surface area. The heaviest concentration of cabling found within this area was located along the southwest wall. The total surface area of cable trays in this area is 95 sq. ft.
There are no combustible liquids in this area. Enclosed combustibles such as cabling in conduit have not been considered in this analysis.
- 3. vggIIbaIIgg_EagangIggs There are two doors which enter this area. One person-nel door enters this area through the north wall from the stairwell and the other personnel door enters this
(' area through the east wall. The door to the stairwell 1

measures 3 ft. wide by 7 ft. high and the door through
' east wall measures 3 ft. wide by 6'-4 1/2" high.
(
- 4. C6@gg_gX6 MINED The only case examined was that of a spreading cable fire which was assumed to originate in the area of heaviest cable concentration in order to present the worst case.
The fire is assumed to start at a point source and spread along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 8.3 feet in each direction along the cable trays before the original point source dies out after 50 minutes. A noximum surface area of 38 sq. ft of cable trays (_ (see Attachment B for a list of trays) will be involved at any one time, which corresponds to a heat output of 668 kW. This heat output is assumed constant throughout the fire duration. -The actual heat output as the fire spreads out o:f the area originally involved would be less since the quantity of cabling involved.at any one time would be less.
- 5. RggULTg The only case examined was that of a spreading cable ,
fire occurring when one personnel doors was open. The fire duretior.'was taken to be 124 minutes, which is the () time required for all of the exposed cabling in the room 2
calcuIa%1on lo. 7 to be consumed. The maximum temperature reached was O)
\_ 539 F, which is below the critical temperature for the structural steel (see Attachment C for results of analysis). Since the resulting fire was fuel controlled with one door open, it will also be fuel controlled if the additional door is opened.
The positions of cable trays relative to structural steel members were examined throughout the area in order to assess the potential for localized heating. Attachment D contains the results of calculations performed to determine the response of *he affected structural members to localized heating. These calculations are conservative because they assume that the entire length O) of the member is subjected to the exposure temperature, whereas, in reality only a short section would be. The duration of each cable tray fire is taken to be 50 minutes which-is the time required for a cable tray to
~
burn to completion. The. cable tray exposures and beam responses are tabula _ad as follows: Case Exposure Separation Member Exposure Final Beam ) Ee- Irsre Dietenes Ires Isse:11El Isme:11El 1 ZB-ZMV180 <1' W16x36 1500 1497

- 4. 90EEE EEOUIEEE es A spreading cable fire was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 10 feet in each direction along the cable trays before the original point source dies out after 60 minutes. A maximum surface area of 286~sq. ft. of cable trays (see Attachment B for a list of trays) will be involved at any one time, which corres-ponds to a heat output of 5,029 kW. This heat output is assumed constant throughout the fire duration. The i
() actual heat output as the fire spreads out of the area originally involved would be less since the quantity of cabling involved at any one time would be less.

4, w-The positions of cable trays relative to structural steel ( members were examined throughout the area in order to assess the potential for localized heating. Attachment D contains the results of calculations performed to determine the response of the effected structural members to locali=ed heating. These calculations are conservative because they assume that the entire length of the member is sub]ected to the exposure temperature, whereas, in reality only a short section would be. The duration of each cable tray fire is taken to be 60 minutes which is the time required for a cable tray to burn to completion.

- 1. 6Bg6_gggg81EIlgN The area under consideration is the Radweste H & V Equip-ment Compartment on the 150' elevation of the Radweste Building (Fire Area 72A). The bounding walls are con-structed of reinforced concrete with an average thickness of 3 ft. (see Attachment A for a sketch of the area under consideration). The surface are of the walls and ceiling is 13,886 sq. ft.
- 2. CgggggIlsLg_Lg6pigg This area contains cable trays. The average loading in
^
the cable trays is 3.96 lbs/ sq. ft. of cable tray surface area. The heaviest concentration of cabling i found within this area was located along the west wall. ; The total surface area of cable trays in this area is , 108 sq. ft. There are no combustible ligulds in this area.

. Calculation No. 11 4.
(-'# C__ASES EXAMINED A apreading cable fire was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction et a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 6.6 feet in each direction along the cable trays before the original point source _ dies out after 40 minutes. A maximum surface area of s 54.4 sq. ft, of cable trays (see Attachment B for a list -- of trays) will be involved at any one time, which corres-ponds to a heat output of 956 kW. This heat output is {} assumed constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally involved would be less since the quantity of cabling involved at any one time would be less.
- 5. REgU Tg The case examined was that of a spreading cable fire occurring. The fire duration was taken to be 79 minutss, which-la the time required for all of the exposed cebling in the room to be consumed. The maximum temperaturr.
o reached was 269 F which is below the critical temperature for the structural steel (see Attachment C for resulta . of analysis). 2
Colculation No. 11 i The cable trays in the area were positioned such that l
\- they did not present a localized heating exposure to the structural steel.
Columr.s in this area are type W12x79. When exposed to a plume temperature of 1500 F the steel temperature of the columns are as follows: Column Column Column Deelenstlen beestien Ires Ilas te 1999 Eleini C10 H.1 - 20.0 W12x79 15 - C11 H.1 - 20.8 W12x79 15

'4. C65EG_EN65INED (q)3 The only case examined was a spreading cable fire which was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 4.8 feet in each direction along the cable trays before the original point source dies out after 29 minutes. A maximum surface area of 20 sq. ft. of cable trays (see Attachment B for a list of trays) will be involved at any one time, which corresponds to a heat output of 352 kW. This heat output is assumed O constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally involved would be less since the quantity of cabling involved at.any one time would be less. .

~The area under consideration is the General Floor Area-East of the Reactor Centerline on the 195'-O'* elevation of the Unit 2 Reactor Building (Fire Area SK). The bounding walls are constructed of reinforced concrete
- with an average thickness of.2.5 ft. - (see Attachment A for a' sketch of the area.under consideration). The surface area of the walls and ceiling is 18,741 sq. ft.
- 2. 99saHEII@bE_kg69ING This area contains cable trays. The average loading in the cable. trays is 8.0 lbs/ sq. ft. of cable tray
() surface area. The heaviest concentration of cabling found within this area was located in the corridor which separates the Reactor Containment and' Ventilation Equip-ment area walls. The total surface area of cable trays in this area is 611 sq. ft. There are no combustible liquids in this area. Enclosed combustibles such as cabling in conduit have not been considered in this analysis.
- 3. YENII66II9N_E6865EIEEE There are several personnel doors which open into this area from other' areas of the plant. Also, this area is - i
~

Ca!=ulosion'WUTYb open to the west general floor area at the south end of the room. The opening is 28 ft. wide by 10 ft. high.
- 4. gegg5_gf651NED A spreading cable fire was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 f t . per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 13'-4" in each direction along the cable trays before the original point source dies out after 80 minutes. A maximum surface area of
- 131 sq. ft. of cable trays (see Attachment B for a list of trays) will be involved at any one_ time, which cor-responds to a heat output of-2,303 kW. This heat output is assumed constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally involved would be less since the quantity of cabling involved at any one time would be less.
i
- 5. BEgULTg The only case exmained was that of a spreading cable 4 fire. The fire duration was taken to be 180 minutes i l
which is the maximum fire resistance rating required for the barrier, and the maximum temperature reached was 395'F which is below the critical temperature for the I) s.- 2 r i

The bounding walls are constructed of reinforced con-(see crate with an average-thickness cf 2.5 ft. Attachment A for a sketch of the area under considera-tion.) The surface area for heat transfer is considered to be the walls and ceiling of the fan room at elevation 214'-O" (Room 529). This was assumed because there is an open grating and open stairway which penetrate the ,\ floor slab separating.the upper and lower rooms which will allow heated gases to flow into the upper room. The heat loss surface area is 8,778 sq. ft.

Calculation No. 16 ? t 5. REpOLTp The case examined was that of a spreading cable fire occurring on the 195' elevation when one personnel door was open. The fire duration was taken to be 180 min-4 utes which is the maximum fire resistance rating required for the barrier and the maximum temperature reached was 465'F which is below the critical temperature for the structural steel (see Attachment C for results o-J analysis.) .Since the resulting fire was fuel controlled with one door open, it will also beffuel controlled if I any additional doors are open. 1 4 I (') The positions of cable trays relative to structural I
%/
steel members were examined throughout the area in order to. assess the potential for localized heating. Attach-ment D contains the results of calculations performed to ; determine the response of the affected structural mem- l bers on the 195' elevetion to localized heating. These i calculations are conservative because they assume that
.I the entire length of the member is subaected to the .c exposure temperature, whereas, in reality only a short section would be. The duration of the cable tray fire for the 195' elevation is taken to be 55.5 minutes which i is the time-required for a cable tray to burn to com-plation. The cable tray exposures and beam response are

the cable trays is 3.53 lbs/sq. ft of cable tray surface , O area. The heaviest concentration of cabling found within this area was located in the southwest corner. The total surface area of cable trays in this area is 85 sq. ft. There are no corbustible liquids in this area.

- 4. CAgEg_ EXAMINED' A spreading cable fire was assumed to originate in the area of heaviest cable concentration in order'to present the worst case. The fire is assumed to start at a point source and spread horicontally along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 5.9 feet in each direction along the cable trays before the original point source dies out after 35.3 minutes. A maximum surface area of 36 sq. ft. of cable trays (see Attachment B for a list of trays) will be involved at any one time, which cor-responds to a heat output of 633 kW. This heat output is assumed constant throughout the fire duration. The
(~T actual heat output as the fire spreads out of the area s/ originally involved would be less since the quantity of cabling involved at any one time would be less.
- 5. REgULfg The only case examined was that of a spreading cable fire occurring when one personnel door was open. The fire duration was taken to be 84 minutes, which is the time required for all of the exposed cabling in the room to be consumed. The maximum temperature reached was 621 F, which is below the critical temperature for the strue'tural steel (see Attachment C for results of
~
analysis). Since the resulting fire was' fuel controlled 2 t i
r. c a EcIn a a osa psTF' m with one door open, it will also be fuel controlled if any additional doors are open. The positions of cable trays relative to structural steel members were examined throughout the area in order to assess the potential for localized heating. Attachment D contains the results of calculations performed to determine the response of the affected structural members to localized heating. These calculations are conservstive because they assume that the entire length of the member is subjected to the exposure temperature, i whereas, in reality only a short section would be. The duration of each cable tray fire is taken to be 35 minutes which is the time required for a cable tray to () burn to completion. The cable tray exposures and beam responses are tabulated as follows: Case Exposure Separation Member Exposure Final Beam Ee Irere Dietence Iree Isme:11El Isme:IEE1 1 3NEIlO 6 ** W24x76 1500 1401 2 2RV10 0" W24x68 1500 1432 3 2RV10 0" W8x20 1500' 1491 4 2RV10 0" Same as Case 1 5' 2RV10 0" Same as Case 3 Columns in this area are encased in concrete.

The bounding walls are constructed of concrete block with a thickness of 8 inches - (see Attachment A for a sketch of the area under consideration). The surface area of the walls and ceiling is 1,813~sq. ft.
- 2. ggggggIIgLg_Lg691gg This area contains cable trays. The average loading in the cable trays is 7.15 lbs/sq. ft. of cable tray surface
() area. The total surface area of cable trays in this area is 138 sq. ft. There are no combustible liquids in this area. Enclosed combustibles such as cabling in conduit have not consi-dered in this analysis.
- 3. YEEII66II9E_ eld 6HEIEEE There are two doors which enter this area. Personnel doors enter this area through.the east and west walls
' respectively. The door through the east. wall measures 3'-6" wide by 8' high.and the door through the west wall measures-3' wide by 7' high.

. () The first case examined was that of a spreading cable fire that was assumed to originate in the area of heavi-est cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 11.8 feet in each direction along the cable trays before the original point source dies out after 72 minutes. A maximum surface area of 94.4 sq. ft.
of cable trays (see Attachment-B for a list of trays) will be involved at any or.c time, whic h corresponds to a heat output of 1,660 kW. 'This heat output is assumed constant throughout the fire duration.- The actual heat output as the fire spreads out of the area originally involved would be less since the quantity of cabling involved at any one time would be less. The second case examined that all the cabling in the room was burning simultaneously. A surface area of 138 sq.ft. of cable trays will be involved which corresponds to a heat output of 2,427 kw. The fire is assumed to burn till all the cabling in the room is consumed in 72 minutes. 4 2

'The first case examined.was that of a spreading cable fire occurring when one personnel door was open. The fire duration was taken to be 104 rainutes, which is the t irne required for all of the exposed cabling in the roorn to be consurned and the rnaxirnurn teroperat ure reached was e
1307 F, which is above the pilot-ignition ternperat ure of the cabling (see Attachrnent C for results of analysis). Since.the resulting fire ternperature was above the piloted-i gnit ion t ernperat ure of the cabling, the next case exarnined was a room fire with all cables burning s irnul t aneous l y. The second case examined considered all'the cabling in I the room involved in a fire occuring when one per' sonne l , door was open. The fire duration was taken to be 72' minutes which is the tirne required for all the exposed cabling in the room to be consurned and t he rna x i rnum t erno-e erature reached 1551 F which is above the critical temp-
, erature for the structural steel. (See attachment C for ,
results of.the analysis.) Since the resulting fire was fuel' controlled with one door open, it will be also fuel controlled if any additional doors are open. l .The positions of cable trays relative to structural steel i - r members were exarnined to assesn' the potential for local-ired heating.

Theso calculations are conservative because they assume that (U~) the entire length of the member is sub3ected to the ex-posure temperature, whereas, in reality only a short section would be. The duration of each cable tray fire 1s taken to be 72 minutes which is the time required for a cable tray to born to completion.

- South of the Reactor Centerline on the 165' elevation of the Unit 2 Reactor Building (Fire Area SJ). The bound-ing walls are constructed of reinforced concrete with an average thickness of 3 ft. - (see Attachment A for a sketch of the area under consideration). The surface area of the walls and ceiling is 17,945 sq.ft.
- 2. ggggugIIg(E_(9691NG This area contains cable trays. The average loading in the cable trays is 4.80 lbs/sq.ft. of cable tray surface area. The heaviest concentration of cabling found within this area was located along the south wall.

s A spreading cable fire was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at-a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 8 feet in each direction 4 along the cable trays before the original point source dies out after 48 minutes. A maximum surface area of 268.7 sq.ft.of cable traya (see Attachment B for a list l of trays) will be involved at any one time, which corresponds to a heat output of 4,722 kW. This heat output is assumed constant throughout the fire duration. i. w) The actual heat output as the fire spreads out of the I area originally involved would be less since the quantity of cabling involved at any one time would be less. t
- 5. RggULTS The case examined was that of a spreading cable fire.
The fire duration was taken to be 180 minutes, which is the maximum fire resistance rating required for the barrier and the maximum temperature reached was 612*F, which is below the critical temperature for'the struc-tural steel,(see Attachment C for results of analysis). The positions of cable trays relative to structural steel () members were examined throughout the area in order to 2

assess the potential for localized heating. One location was found where a cable tray was positioned to present
< a localized heating exposure to a structural member.
Attachment D contains the results c ' the calculations performed to determine the response of the affected structural member to. localized heating. This calculla-I tion is conservative because it assumes that the entire
- length of the member is subjected to the exposure temp-erature, whereas, in reality only a short section would i
be. The duration of the cable tray fire was taken to be 48 minutes which is the time required for the cable tray to burn to completion.

The case examined was that of c spreading cable fire. () Excess air was available for combustion through the 1 2
s Calculation No. 22 opening on the west side of the room. The fire duration O was taken. to he 180 minutes which is the maximum fire resistance rating required for the barrier and the maxi-mum temperature reached was 1195 F, which is above the critical temperature for the etructural steel (see Attachment C for results of analysis). Since the resulting fire temperature was above the piloted ignition temperature of the cabling (900 F) the spreading cable fire scenario is not valid. Therefore, a second case was considered which was a ventilation controlled fire supplied by the opening in the west vall of the room. All other room doors were considered to be closed. The ventilation controlled m heat output was 15,775 kW and the fire dure tion was taken to be 180 minutes, which is the maximum required rating for the fire barriers. The final gas temperature is 1591'F, which is well above the critical temperature 1 of the structural steel (see Attachment C). While it is possible to postulate additional doors being open, this will only result in more severe fires and the steel already fails under this exposure. The positions of cable trays relative to structural steel t I members were examined throughout the area in order to j
- l assess the potential for localized h'esting. Thirty-one [
(31) locations were encountered where cable trays were i positioned so as to present a localized heating exposure 3
Calculation No. 22 to the structural steel. Attachment D contains the results of calculations performed to determine the re-sponse of the affected structural members to localized heating. The duration of each cable tray fire is taken to be 83 minutes which is the time required'for a cable d tray to burn to completion. The results of th'ese calcu-lations are summarized below.

(} A spreading cable fire was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 10.43 feet in each dir-ection along the cable' trays before the original point source. dies out after 63 minutes. A maximum surface aret of 754 sq. ft. of cable trays (see Attachment B for a list of trays) will be involved at any.one time, which corresponds to a heat output of 13,258 kW. However, this O heat output is greater than available openings can support. 'Therefore, ventilation controlled fires were postulated. i The first case examined was that of a ventilation i controlled fire with one personnel door-open. The 6 second case examined was that of a ventilation controlled ? fire with both personnel doors open.

temperature at this time is 688 F, which is below the critical temperature for the structural steel (see Attachment C for the results of this analysis ). t I The second case examined considered both 3 ft. wide by 7 ft. high doors open, which corresponds to a 4 ventilation controlled heat output of 9,008 kW. The fire duration was taken to be 180 minutes which is the maximum fire resistance rating required for the barrier, and the maximum temperature reached was 1,082 F which is below the critical temperature for the structural steel- (see Attachment C for results of this analysis.) Since there are no more openings into this area, 9008 kW is the maximum heat output for the cable' spreading area. The positions of cable trays relative to structural steel members were examined throughout the area in order to assess the potential for localized heating. All beams within this area are sub]ected to local heating exposures and will not survive the effects of a local heating fire.

.The only case examined was that of a ventilation con-trolled fire with one door open. The fire is assumed to occur at the ventilation controlled rate until all.
of thc' combustibles in the room are consumed. Addition-e al ventilation controlled cases were not investigated because all steel within this room fails from the effects of a one door open ventilation controlled fire.

-A spreading cable fire was assumed to originate in the aree.of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will opread a distance of 8 feet in each direction along the cable trays before the original point source dies out after 47 minutes. A maximum surface area of 23 sq.ft. of cable trays (see Attachment B for a tray list) will be involved at any one time, which corresponds to a
^ heat cutput of 404 kW. This heat output is assumed
\- constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally involved would be less since-the quantity of cabling >
involved at any one time would be less.
- 5. EggUL~5 The case examined was thet of a spreading cable fire
. occurring when one personnel door was open. The fire duration as taken to be 180 minutes which is the maximum. fire resistance rating required for the barrier ,

() Combustible loading in the area consists of 28 gallons of lube oil contained in the RHR Pump. This quantity was doubled to account for possible maintenance activities in this area. This area a'so contains cable trays. The average loading in the cable trays is 3.7 lbs/ft of cable trays surface area. The total surface area of cable trays in this $ area is 73 sq. ft.

( personnel doors exist this area through the south wall at the 91'-6" and 116'-O" elevations respectively. The door at elevation 91'-6" measures 3 ft. wide by 5'-10" ft. high. The door at elevation 116'-O" measures 3 ft. wide by 7 ft. high.
- 4. C6ggg_EX65IEgD The first case examined was that of a ventilation controlled fire with one personnel door open. The fire is assumed to occur at the ventilation controlled rate until all of the combustibles in the room are consumed.
The second case examined was that of a ventilation controlled fire with two personnel doors open. The fire () is assumed to occur at the ventilation controlled rate until all of the combustibles in the room are consumed.
- s. gggubI!
The first case examined considered a single 3 ft. wide - by 5 ft. 10 inch high door open, which corresponds to a ventilation controlled heat output of 3425 kW. At this heat output, the fire will consume all of the combusti-bles in the room in 56 minutes. The gas temperature at this time is 851 F, which is below the critical tempera-ture for the structural steel (see Attachment B). h' The ventilation controlled burning rate of 3426 kW is equivalent to the heat output from a pool fire with an area of 10.8 sq. ft.(pool diameter of 3.7 ft.)

() The second case examined considered both doors open, which corresponda to a ventilation controlled heat ouput of 7,908 kW. At this heat output, the fire will consume all of the combustibles in the roon in 24 minutes. The gas temperature at this time is 1187 F, which is above the critical temperature for the structural steel (see Attachment B), however, none of the structural members will reach their critical temperature of 1100 F. The ventilation controlled burning rate of 7.908 kW is equivalent to the heat output from a pool fire with an area of 24.9 sq. ft. (pool diameter of 5.63 ft.).

~
area of the cable trays in this area de'95 sq. ft. There are no combustible liquids in,this area. Enclosed combustibles such as cabling in conduit have not been considered in this analysis.
- 3. vggIIbaIIgN_eaBangIgBE There are two d'oors provided for.this area. .One personnel door enters this area.,through the south wall from the stairwell and the other personnel door exits 1

Calculation No. 41 this area through the east wall. The door exiting into O) s the stairwell measures 3 ft. wide by 7 ft. high, the other door measurea 3 ft. wide by 6'-4 1/2" high.
- 4. CASES _ EXAMINED A spreading cable fire was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft. per hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 6.5 feet in each direction-along the cable trays before the original point source dies out after 39 minutes. A maximum surface area of 37 sq. ft. of cable trays (see Attachment B for a list of trays) will be involved at any one time, which corres-ponds to a heat output of 651 kW. This heat output is assumed constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally involved would be less since the quantity of cabling involved at any one time would be less.

.tn> consumed and the maximum temperature reached was 514 o F which is below the critical temperature for the structural steel (see Attachment C for results of analysis.) Since the resulting fire was fuel controlled with one door open, it will also be fuel controlled if any additional doors are open.
The positions of cable traym relative to structural steel members were examined throughout the area in order to assess the potential for localized heating. Attachment D contains the results of calculations performed to determine the response of the affected structural members
- to localized heating. These calculations are
() conservative because they assume that the entire length of the member is sub]ected to the exposure temperature, whereas, in reality only a short section would be. The duration of each cable tray fire is taken to be 39 minutes which is the time required for a cable tray to burn to completion. The cable tray exposures and beam responses are tabulated as follows: Case Exposuro Separation Member Exposuge Final Beam Het IEers' Dietsecs Ires Isme:1_El Ismezi'_El 1 C3KVO3 3" 16WF36 1500 1490

- 1. 6BE6_DEE9BIEII9N The area under consideration is the Redwaste Control Room on'the 135' elevation of the Radweste Building (Fire Area 75). The bounding walls are constructed of reinforced concrete with an average thickness of I ft. -
(see Attachment A for a sketch of the area under consideration). The surface area of the walls and ceil-in is 2,303 sq. ft.
- 2. 995aESIIBLE_L9691H9 This area contains cable trays. The average loading in the cable trays is 10.6 lbs/ sq. ft. of cable tray (2) surface area. The heaviest concentration of cabling found within this area was located in the northwest
., corner. The total surface area of cable trays in this area is 455 sq. ft. i There are no-combustible liquids in this area. Enclosed combustibles such as cabling in conduit have not been considered in this analysis.

Calculation No. 54 maximum fire resistance rating required for the barrier. The maximum temperature reached was 2,082 F, which is above the' piloted ignition temperature for the cabling (see Attachment C for resulats of analysis). Therefore, the spreading cable fire scenario was invalid and a ventilation controlled fire was postulated. The second case examined considered a single 3 ft. wide by 7 ft. high door open, which corresponds to a ventilo-tion controlled heat output of 4,504 kW. The duration of the fire was taken to be 180 minutes, which is the maximum required rating for the fire barriers. The gas temperature at this time is 3,032 F, which is above the critical temperature for the structural steel (see O. . Attachment C). The positions of cable trays relative to structural steel members were examined throughout the area in order to assess the potential for localized heating. Attachment D contains the results of calculations performed to determine the response of the affected structural members
-to localiced heating. These calculations are conservative because-they assume.that-the entire length of the member is'sub3 ected to the exposure temperature, whereas, in reality only.a short section would be. -The duration of each cable. tray fire is taken tolbe 106 e~ minutes-which is the time required for a cable tray to

The heat release rates required of floor level transient combustible fires to produce plume temperatures of 1100 F, 1300 F and 1500 o F at the bottom flange of the beam have been deter-mined and tabulated below.

surface area. The heaviest concentration of cabling found within this area was located along the west well. The total surface area of cable trays.in this area is 198 sq. ft. There are no combustible liquids in this area. Enclosed combustibles such as cabling in conduit have not been considered in this analysis.

.The only case examined was a spreading cable fire which was assumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direcction at a rate of 10 ft. per hour and instantaneously up any verhical trays encountered. The fire will spread a dis-tance of 5.0 feet in each direction along the cable trays before the original point source dies out after 30.5 min-i utes. A maximum surface area of 21 sq. ft. of cable trays (see Attachment B for a list of trays) will be in-r volved at any one time, which corresponds to a heat out-l put of 369 kw. This heat output is assumed constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally involved i -
would be less since the quantity of cabling involved at any one time would be less. 1

The positions i of ceble trays relative to structural steel members i were examined throughout the area in order to assess the potential for localized heating. Attachment D con-tains the results of calculations performed to determine the response of the affected structural members to local-iced heating. These calculations are conservative because they assumed that the entire length of the member r is s5bjected to the exposure temperature, w h e r e a's , in reality only a short section would be. The duration of each cable tray fire is taken to be 30 minutes, which is the time required for a cable tray to burn to completion.

- 1. 6BE6_9EE9BIEII98 The area under consideration is the General Floor Area East of the Reactor Centerline on the 195'-O" elevation of the Unit 3 Reactor Building (Fire Area 13K). The bounding walls are constructed of reinforced concrete with an average thickness of 2.5 ft.
(see Attachment A for a sketch of the area under consideration.) The' surface area of the walls and ceiling.is 18,741 sq. ft.

- 4. C6ggg_gX6MiggD A spreading cable fire was oscumed to originate in the area of heaviest cable concentration in order to present the worst case. The fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 ft. por hour and instantaneously up any vertical trays encountered. The fire will spread a distance of 8.3 feet in each direction
). along the cable trays before the original point source ( dies out after 50 minutes. A maximum surface area of 98 4 sq. ft. of cable trays (see Attachment B for the tray list) will be involved at any one-time, which corresponds to a heat output of 1723 kW. This heat output is assumed constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally involved would be less since the quantity of cabling ! involved at any one time would be less.
