d I. INTRODUCTION Structural steel members which form a part of or support fire barriers should be capable cf withstanding the fire exposure presented by all com-bustibles contained within the fire area. Structural steel need not be protected if it can withstand this fire exposure. The metho(clogy is in-tended as a screening tool for evaluating the severity of fire exposure to structural steel members. This is a two part evaluation: first, the fire exposure is determined and second, the response of the structural steel member is assessed. The approach as described treats the evaluation in a systematic way by assess-
'ing simple and conservatively realistic limitations on the combustion pro-cess, the resultant room environment and finally, temperature histories of the structural steel members when required.
The conclusions reached will then be used to determine acceptability of the structural steel as a unique part of the fire barrier and to evaluate any O needed modifications if deemed necessary. V 1: v I
(~) v II. ASSESSING FIRE DEVELOPMENT The types of fixed combustible materials found in a nuclear power plant which can burn in such a way as to present a significant fire exposure to the general area in which they are located are very few. The prevalent materials encountered in the plant areas analyzed were cable insulation and lubricating oil. .The insulation and jacketing on the cabling in cable trays are susceptible to ignition f.om internal or external sources. The heat output from a cabl3 tray fire will affect 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 com-Qustibles contained within substantial metal enclosures (e.g. cabling in conduit and charcoal in filter units) have been assumed not to contribute to fires. The methodology for assessing fire development can be divided into three different parts: limits on fire development, fire modeling techniques, and local heating effects. Each part will be examined in turn. O - l 2 f~% G n,. - . - .
d III. LIMITS ON FIRE DEVELOPMENT In this section, practical limitations which govern the combustion process in a room are discussed. This will include physical limitations on the combustion of any fuel and fire test data regarding the burning character-istics of cable trays and combustible liquids such as lube oil. A. Ventilation Limited Fires _ 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. A balance is set up at each opening into the enclosure 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. Many relationships, both empirical and analytical, have been developed to predict velocity profiles and mass flow rates at openings during ventila-tion controlled fires as well as resultant heat release rates and peak fire temperatures. This analysis employs a relationship developed by Coul-bert(1) which pred! ts the heat release rate that can be supported by the fire induced air flow. The relation is: Q = 1580 A d where Q = heat output (kW) A = area of. opening-(m2) H = height of-opening (m) The term A/iiis often called the ventilation factor. Any empirical rela-tionship for the heat release rate or mass burning rate will be propor-tioral 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. 1 p- 3 b a - e y p ae -
C The rate of burning is independent of the type of combustibles 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.
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 systems were assumed not to contribute to the ventilation rate, since installed fire dampers will actuate. B. Fuel Controlled Fires When excess air is available for combustion, the heat output of ',he fi re will be dependent on the free burning characteristics of the t ~osed com-bustibles. The fixed combuctibles 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 Umbustible liquids such as lubricating oils. (-
- 1. Cable Tray Burning Characteristics The best available data on free burning cable trays containing hypalon and neoprene jacketed cables 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 0.1 (lb/ min)/f t2 of cable tray or a heat release rate of 1000 (BTV/ min)/ft2 (190 KW/m2), Another parameter vital to cable tray fire assessment 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 fi re . For l this analysis a more conservative figure of 10 ft/hr has been assumed, n 4 (v) .
(V3 An important parameter that is develcped for 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 jacketing per square foot of cable tray surface area. It should not be confused with the combustible loading 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 of 0.1 (lbs/ min)/ft2 to determine the time it takes for a tray to burn to completion. These parameters were applied to determine the worst case fire involy-ing 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 assumed to spread out along horizontal trays at a rate of 10 feet per hour and instantaneously up any verti-cal trays encountered. The area of cable tray which has become involved when the original point of the fire bums itself out defines the steady state fire size. This quantity is multiplied by 1000 (Btu / min.)/ft2 (190 kw/m2) to determine the maximum heat release rate possible from a spreading cable fire in the area. The duration of the spreading cable fire is taken to be the time re-quired 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 nf the fire through its entire duration. This is a very con-servative 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 temperature of the cabling. The ignition temperature of the type of cabling installed at t.imerick is approximately 1100*F. If the area temperature exceeds 1100*F, it must be assumed that all cables are burning simultaneously unless the fire- becomes ventilation controlled, y ~. 5

I b :2. Lubricating 011 Burning Characteristics 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 neces-sary tu have a high spill rate to produce a significant heat output. In this case the mass of the oil will fall to floor level and form a pool. Pool fires of varying sizes have been studied extensively for many years. Hydrocarbon lioulds 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 con-sequent 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 is that amount ( . contained within equipment. To accomodate the possibility that a fire could occur where the lubricants are being changed, all lubricating oil quantities have been doubled in the calculations. Under free burn-ing conditions a variety of oil leakage rates and consequent fire _dur-ations and heat outputs are possible. I 1 t l- f~s 6 i-l
N N IV. FIRE MODELING TECHNIQUES The methodology for analyzing the fire resistance of structural 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 ma-terials and geometry for the compartment under consideration as input for a simple and conservatively realistic fire model which predicts a gas temper-ature for the area. This model should not be confused with sophisticated models which attempt to predict temperature profiles and/or gas concentraticas throughout the room from ignition of the fire 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. Heat Balance Method Writing a heat balance for the compartment is one of the most straightfor-(d' ward 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 this simplifi-cation:
- 1. Radiative and convective heat losses through openings in the enclosure are negligible (see Berry 5).
- 2. Heat loss through. the walls will be dominated by the thermal inertia of the barriers, o C pK (assumption of semi-infinite slab approximation).
The massive reinforced concrete and concrete block construction prevalent throughout nuclear power plants plays a very important role in determining the time-temperature history of compartment fires. The thermal penetration time c/ a wall or ceiling / floor slab is defined as the period of time re-quired 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 dif fusivity of the wall material and its thick-n ness are known.
\~ ) -
7
The thermal penetration time for 12-iach thick concrete walls 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. 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. The heat balance equation can be described as follows: Q = heat release rate (kw) of fire (Q = 1580 Aodfor ventilation controlled fires) 4 Q=oAn t (Tg 4 - Tw4 ) = radiant heat transferre~d to boundary Q= (upCo kf2 At (Tw-To) = conductive heat loss through boundary 2E
/~'T : To get Tg as a function of t these equations can be solved to yield the t %') following expression: .,
h Tg= Q + To + Q /t- 4 oAtn AK t / where Q = heat release rate (kW) of fire K = 1/2 (irk p Cp) h n = function of emissivity of fire gases and boundary walls At . = total heat loss surface area of boundary This. relationship is similar in form to that developed by Harmathy (6) except the heat release rate is defined by either the ventilation factors or the fuel surface controlled fire. This is not an iterative process. The formula can be used to determine the gas temperature at any time dur-ing the course of the fire. A' conservative assumption that has been made in the application of the model is that no heat will be lost through the floor. 8

-s V. LOCAL HEATING EFFECTS The fire models just discussed are used to determine generalized condi-tions in the enclosure where the fire is occurring. However, plumes of heated gases will rise above burning objects and create localized hot zones that can effect the steel members 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.
The problems of localized heating can best be quantified by applying fire plume models to predict gas temperature profiles. This same approach can be applied to the evaluation of the impact of transient combustibles on structural steel and on cable ignition. A. Plume Modeling: Alpert and Ward (8) present empirical relationships for temperature in-crease, a T, with respect to height above fuel package, H, and size of fire,Q. This general relationship is as follows: p- aT= 300 (kQ).667 H-1.67
\__/ -
Using this relationship, " safe" separation distances from fuel pac 6 ages can be evaluated for localized heating of steel. If these relations pre-dict a plume temperature at the level of the bottom flange of the steel higher than the critical temperature of the steel, the heating of the steel is assessed.
- 1. Cable Tray Fires Cable tray fire test data was examined to establish temperature pro-files above burning cable trays. Tests performed by Sandia Labora-tories (7) and FMRC/EPRI (2) show that temperatures in the vicinity of 1500*F are reached in the flame region immediately above tne sur-face of a burning cable tray. This temperature drops rapidly with increasing distance above the surface of the cable tray.

. ...w. . ;& , s . _ _ ,
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 heating of steel, the heat release rate from a stack of trays must be estimated and used to calculate plume temper-ature 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 tray 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 follow's: T = 1100*F H = 5.41 f t 1300'F 4.87 ft 'i 1500*F 4.45 ft Applying the plume relationships to other cable arrays is necessary to estimate the plume ef fects of other stacks of trays on overhead struc-tured steel. This was done by using the ratio of heat release rates which are directly proportioned 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 T g T= g 1300*F Tg = 1100*F 1 2.0 ft 2.21 ft. 2 2.7 ft 2.98 ft. 3 3.1 ft 3.40 ft. 4 3.5 ft 3.86 ft. 5 3.8 ft 4.20 ft. 6 4.1 ft 4.50 ft. For evaluation of iocal ef fects of cable fire plume the data were rounded off and applied as separation requirements: No. of Trays Distance from top tray to bottom of beam 1- 2 ft 2 - 3 ft 5 5 ft 10
0 V These criteria were used to identify areas where stacks of cable trays were located less than these " safe" separation distances from strucural steel. These areas were then evaluated regarding the cable loading, size of steel member, and number of trays to determine the potential effects on the structured steel. Cable trays located within one foot of the bottom of steel beams were assumed to subject the beam to a constant temperature of 1500*F for the period of time it takes the tray to burn to completion (cable tray combust-ible loading divided by mass burning rate for tray fires). Trays closer than the separation distances previously identified but greater than 1 foot were assumed to subject the beam to a constant temperature of 1300*F for the period of time it takes for the tray to burn to completion.
- 2. Pool Fires Realistic relations for determining temperature distributions for fire plumes have been developed by Heskested of FMRC (9). These relationships p are based on large scale fire tests involving a variety of liquid fuels.
d Fire plumes are considered to have a virtual origin (point source) frou which the plume can be considered tJ emanate. A virtual origin has no phy-sical meaning for fires involving most types of solid and liquid fuels. For liquid pool fires the virtual origin height, H, o (relative to floor level) can be theoretically predicted using the following relation: Ho = -1.020 + 0.083 Q 4 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 equa-tion is used to determine the temperature to which the structural steel located above the pool will be subjected.

Cl VI. TRANSIENT COMBUSTIBLES The ef fect of transient combustibles on the fire exposure to structural steel was also evaluatea. This evaluation included both the effects on area calculations using the heat balance method and 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. Area Effects The evaluation of transient combustibles using the heat balance method falls into three (3) categories. The first is fires controlled by ventila-tion openings (see Section III). For this case, transients could affect the duration of the fire but would. not effect the heat release rate. The heat value in Btu's of the total quantity of transients can be calculated by determining the extended duration necessary to e'xceed the acceptance criteria and multiplying this extended duration by the ventilation limited (] heat release rate. A,/ . The second category is those transients accounted for in the early stages of a cable fire by assuming a constant heat release rate at the maximum value. This quantity can be estimated assuming a geometric growth of the fire. An example is shown graohically in Figure 1. The third category is the additive effects of transient combustibles on in-situ combustibles. These effects were analyzed by applying the heat balance method for different unitized heat release rates (heat release rate from fire divided by the heat loss area, Q/At ) to calculate the duration of fires required, to -exceed the area temperature acceptance criteria of
~100*F. These results are plotted in Figure 2. This figure is used to determine the maximum fires that did not exceed the acceptance criteria.
As can be seen, this does not provide a unique olution since fire size and duration provides an infinite number of combinations. For analysis purposes, -only the maximum size fire for the duration calculated in the area calculation was listed, n k-) 13

' The hazards of transient combustibles may be either that of an ignition source for insite combustibles . (i.e. cables) or as a direct exposure to structural steel. To evaluate the potential effects of transient combusti-bles, the plume correlation relationships previously outlined were used to develop plots of height above fuel packages vs. fire size for three differ-ent temperatures; 1) 1100 F 2) 1300'F and 3) 1500*F.'
Figure 3 shows the relationship of fire size to height above fuel array for these temperature criteria. IlEAT RELEASE RATE (BTU /SEC) 5pOO 10.000 ts,oco 20, ooo

-( I The approach taken in this analysis was to quantify the size fire in Btu /
sec necessary to reach plume. temperatures at the bottom flange of the steel of 1100*F,1300 F, and 1500*F using Figure 3. For plume temperatures of 1300*F 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 combusti-ble material. it is important to remember that the heat release ra,te 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 wood-en pallets, flaanable liquids and storage related commodities. Limited data exists on " trash" or health physics supplies. To develop some guid-ance for these commodities, Sandia Laborataries tests for ignition source fire characterization (12) were evaluated. The temperature profiles re-corded during these tests were used to estimate maximum heat release rates for Tests 3, 4, 5 and 10. These results are contained in Table 1.

<-wg Vil STRUCTURAL STEEL RESPONSE s#
Once the area and localized exposure temperatures have been determined for the various fires that could occur in an area, an assessment is made of the effects of these temperatures on the structural steel mem-bers. An 1100*F cross-sectional average temperature of the steel mem-ber has been established as the temperature below which no protection of the steel beams is required and the member is capable of supporting the fire barrier. This is a conservative criteria because it neglects the added fire enddrance provided by end restraints and composite Con- , struction. The following measures are used in veri fying compliance with this 1100*F temperature criteria:
- 1. If the area and localized peak temperatures are less than 1100 F, then the unprotected structural steel member is acceptable.
- 2. If the area or ' localized peak temperature is greater than 1100*F, the temperature of -the steel will be calculated as described in the following sections.
() a. If the calculated steel temperature is less than 1100*F, then the unprotected structural member is acceptable.
- b. If the calculated steel temperature is greater than 1100*F, then either the member will be coated to provide the required fire resistance or measures will be taken to reduce the fire exposure to the beam to a level such that the member tempera-ture will be less than 1100"F.
A 1100*F cross sectional average temperature of the steel member has been established for columns with similar verification steps. 18 O v

r3 Heating of Structural Steel Members U The temperature of the structural steel member is determined using the unsteady state heat transfer calculation outlined by Stanzak (10). A T = 231 JJ (Ta -Tj ) a t G Where AT = temperature rise in steel member during interval t (C) U = surface of steel member exposed to fire (m2 /m) G = weight of steel member (Kg/m) Ta = average fire temperature during interval (*C) Tj = temperature of steel member at beginning of interval (*C) at = time interval in minutes Since the steel temperature rise is calculated over a time interval, a simple iterative process is set up where the steel temperature rise is added to the previous steel temperature for the next iteration. In all cases the peak fire temperatures have been used as a constant input to the steel temperature calculations. y, This. approach for evaluating effects of localized plumes incorporates a major conservatism in that only a portion of the beam's length would be heated rather than the entire length of the beam. Even though this is the case, no credit has been taken for conductive heat losses along the beam. l k -

CONSERVATISMS
.R b
The following conservative assumptions were used in this evaluation.
- 1. No convective heat losses through openings: although combustion air is allowed in, no heat losses via combustion gas leaving the compart-ment are allowed.
- 2. No radiation heat losses through openings.
- 3. No heat losses through the floor: in calculating heat loss 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 jacketed cable and was applied to mass burning rates developed from large scale tests.
- 5. High heat release rates for fuel controlled cable fires: The heat (h release rate from a spreading cable fire is conservatively high based
'& on the high fire spread rate of 10 ft/hr, the high heat release rate per unit area of tray (from 4), the selection of the origin in the area where trays are most dense, and using the maximum heat release rate throughout the fire duration.
- 6. Localized heat of steel: Localized heating of the steel assumes expo-I sure of the entire exposed surface area to the plume and temperature i
at the bottom. flange, regardless of the beam depth and ignores conduc-tive heat losses down the length of the beam, t 2-1 ' p\_/ , i

- 1. AREA DESCRIPTION The area under consideration is the RHR Heat Exchanger and Pump Room, Room 102, on the 177' elevation of the Unit 1 Reactor Building (Fire Area 32)
(see Attachment A for sketch of area). The bounding walls of the area are of ret.iforced concrete construction with an average thickness of 3 ft. The total surface area for heat transfer is 7848 ft2 (see Attachment A for calculation of areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of 72 gallons of lubricating oil contained in the RHR pump motors. For the analysis this quantity was doublea to account for possible maintenace activities in the area. There are two cable trays in the room - one located along the east wall, the other along the west wall. The total surface area of the cable trays is 52 ft2 with an average combustible loading of 1.5 lbs/f t 2 of cable tray surface.
l (,) 3. VENTILATION PARAMETERS There are four doors which enter the area. Two watertight doors measuring 3' wide by 5'10" high enter the area on the 177' elevation and two steam-tight doors measuring 3' wide by 7' high enter the area on the 201' eleva-tion.
- 4. CASES EXAMINED.
Two cases were examined, each assuming a lube oil fire involving 144 gal-lons of lubricating oil. Case number one assumed the lobe oil fire with one steamtight door open and case number two assumed both steamtight doors open.
- 5. P.ESULTS Case number- one considered only one 3' x 7' door open which corresponds to a ventilation controllea heat output of 4504 kW. At this heat output the fire would consume the 144 gallons of lube oil in 85 minutes. The gas temperature at this time would be 841'F, which is below the critical
/"<j l 1 %,/
temperature of the structural steel (see Attachment B). l l 1-1 1 ( .
The ventilation controlled burning rate of 4504 kW is equivalent to the
-( heat output from a pool fire with an area of 14 f t2 (pool diameter of approximately_4 ft). In order to assess the effect of the plume of heated gases above the pool fire on the structural steel support'ing the intermedi.
ate grating at the 201' elevation, Hesketad's relations will be used: Virtual point source determination: Zo = -1.02D + .083 Q 4 = 1.09 m Plume te .ierature at bottom of structural steel supporting the 217' eleva-tion floor slab. 4 To = 9.1[T= /(gcpp 2 . 2)].333 Oc.667 (Z - Zo)-1 67
.To = 103*K temperature rise T = 253*F temperature of fire plume The plume temperature is below the critical temperature of the structural steel.
-Case number two considerad both 3' x 7' doors open which corresponds to a Q ventilation controlled burning rate of 9008 kW. At this heat output the fire would consume the 144 gallons of. lube oil in 44 minutes. The gas temperature at this time would be 1118'F which is above the critical temperature of the structural steel (see Attachment B). The W24X68 beam reaches 1094*F after 44 minutes. (see Attachment _C).
.The ventilation controlled burning rate of 9008 kW is equivalent to the heat output from a pool fire with an area of. 28 f t2 (pool diameter of approximately 6 ft). .In order to assess the effect of the plume of heated f) gases above the pool fire on the structural steel supporting the intermedi-ate grating at the 201' elevation, Hesketad's relations will be used:
Virtual point source determination: r Zo = -1.020 + .083 Q 4 = 1.32 m Plume . temperature at bottom of structural steel supporting the 217' eleva- ! tion floor slab. 1-2 i l L
ATo = 9.1[T=/(gcp 2 p. 2)].333 g .667 (Z - Zo)-1.67 a To = 169*K temperature rise T = 372*F temperature of fire plume The plume temperature is below the critical temperature of the structural l steel. The cable trays in this area were positioned such that they did not present a localized heating exposure to the structural steel. 1 Columns in this area are W14X730. When exposed to a plume temperature of 1500*F for 44 minutes, the steel temperature does not exceed 590 F.
- 6. EFFECT OF TRANSIENT COMBUSTIBLES The fire examined was ventilation controlled and had a duration of 44 minu'es.
t The temperature at this time exceeded 1100"F, therefore, no transient materials were quantified. rA The ceiling height in the area is 20'3". This distance is measured from k the floor slab to the bottom of the largest structural stael member in the area, which is a W24X68. The heat release rates from transient combustibles in the area necessary to reach plume temperature of 1100*F,1300*F and 1500*F' at the bottom flange of the beam are listed in the table below. For temperatures greater than 1100*F, the time required to heat the steel to 1100*F are also listed. T (*F) 0 (kW) Time to 1100*F (min) 1100 12,654 1300 16,134 21 min 1500 20,457 15 min o 1-3

LIMERICK GENERATING STATION O 1. AREA DESCRIPTION The area under consideration is the Core Spray Pump Room, Room 110, on the 177' elevation of the Unit 1 Reactor Building (Fire Area 35) (see Attach-ment A for sketch of area). The bounding walls in the area are of rein-forced concrete construction with an average thickness of 3 ft. The total surface area for heat transfer is 2749 ft2 (see Attachment A for calcula-tion of areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of 24 gallons of lubricating oil contained in the core spray pump. For the analysis this quantity was doubled to account for possible maintenance activities in the area. A single cable tray having 37 ft2 of surface area with an average combustible loading of .5 lbs/f t2 of tray surface area.
- 3. VENTILATION PARAMETERS A single watertight door measuring 3' wide by 5'10" high is located in the west wall of the room.
4.- CASES EXAMINED A lube oil fire was assumed in the area involving 48 gallons of lubricating oil. The door entering the area was assumed to be open. This is an opening area of 17.5 ft2 which results in a ventilation controlled maximum heat output of 3417 kW. l S. RESULTS' With one door open, the resulting ventilation controlled heat output of 3417 kW will consume the 48 gallons of lube oil in 37 minutes. The gas i temperature at this time would be 1128*F which is above the critical temperature of the structural steel (see Attachment B). The W27X84 beam will be heated to 1070*F in 37 minutes if exposed to a constant temperature of 1128'F. (See Attachment C). The ventilation controlled burning rate of 3417 kW is equivalent to the l

- 1. AREA DESCRIPTION The area under cons? 'eration is the Core Spray Pump Room, Room 113, on the 177' elevation of the Unit 1 Reactor Building (Fire Area 36) (see Attach-ment A for sketch of area). The bounding walls in the area are of rein-forced concrete construction with an average thickness of 3 ft. The total surface area for heat transfer is 2976 ft2 (see Attachment A for calcula-tion of areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of 24 gallons of lubricating oil contained in the core spray pump. For the analysis this quantity was doubled to account for possible maintenance activities in the area. A single cable tray having 34 ft2 of surface area with an average combustible loading of .5 lbs/ft2 of- tray surface area is located along the north wall. '
- 3. VENTILATION PARAMETERS A single watertight door measuring 3' ' wide by 5'10" high is located in the west-wall of the room.
- 4. CASES EXAMINED A lube oil fire was assumed in the area involving 48 gallons of lubricating oil. The door entering the area was assumed to be open. This is an opening area of 17.5 ft2 which results in a ventilation controlled maximum heat output of 3417 kW.
l S. RESULTS. With. One door open, the resulting ventilation controlled heat output of 3417 kW will consume the 48 gallons of lube oil in 37 minutes. The gas
-temperature at this time would 1072*F which is below the critical temperature of the structural steel (see Attachment B).
The ventilation controlled burning rate of 3417' kW is equivalent to the heat o'Itput from a pool fire with an area of 11' ft2 (pool diameter of approximately 4 ft). In order to assess the, effect of the plume of heated , 7-1 r _ ~- -. _.

It is concluded that there is no problem due to localized heating of the structural steel as a result of the maximum pool fire that can be supported by the available air flow into the room. The cable tray in the area was positioned such that it did not present a localized heating exposure to the structural steel. 6. EFFECT OF TRANSIENT COMBUSTIBLE S _S The fire examined was ventilation controlled and had a duration of 37 minutes. The temperature at this time was 1072*F. Since this temperature approaches the critical temperature of 1100*F, no transient materials were quantified. The ceiling height in the area is 20 feet. This distance is measured from the floor slab to the bottom of the largest structural steel member in the area, which is a W27X145. The heat release rates from transient combustibles in the area necessary to reach plume temperature of 1100*F,1300*F and 1500*F at the bottom flange of the beam are listed in the table below.

- 1. AREA PESCRIPTION The area under consideration is the Sump Room, Room 115, on the 177' eleva-tion of the Unit 1 Reactor Building (Fire Area 39). The bounding walls of the area are of reinforced concrete construction with an average thickness of 2.5 ft.
The total surface area for heat transfer is 2595 ft2 (see Attachment A for sketch and calculation of surface areas).
- 2. COMBUSTIBLE LOADING The combustible loading in this area consists of cable insulation in cable trays. The total surface area of the cable trays is 96 ft2 with an average combustible loading of 1.5 lbs/ft2 of cable tray surface area. There are no combustible liquids in the area.
- 3. VENTILATION PARAMETERS This room is open to the Corridor Passageway, Room 118. There are two doors which enter into the Sump Room. One door measuring 3' wide by 5'10" high p
'~'
is located in the east wall, and one door measuring 3' wide by 7' high is located at the entrance to the stairwell.
- 4. CASES EXAMINED With the light combustible loading in this area, tne assumption that all cables are burning simultaneously would present the worst case. With all cables burning simultaneously, a surface area of 96 ft2 would be involved.
This corresponds to a heat output of approximately 1700 kW. With all combustibles issumed to be burning simultaneously, the duration of the fire would be 1.5 lbs/ft2 * .1 lb = 15 minutes, min /ft2
- 5. RESULTS With all the cable trays in the area assumed to be burning simultaneously and a 3' wide by 5'10" door open, th'e resulting fire was fuel controlled.

- 1. AREA DESCRIPTION The area under consideration is the Safeguard System Access Area, Room 200, on the 201' elevation of the Unit 1 Reactor Building (Fire Area 42A). The bounding walls of the area are of reinforced concrete construction with an
. average thickness of 2.5 f t. The total surface area for heat transfer is 8611 ft 2 (see Attachment A for sketch and calculation of surface areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of the cable insulation located in cable' trays. The total surface area of the cable trays is 684 ft2 witn an average combustible loading of 3.5 lbs/ft2 of cable tray surface area.
There are no combustible liquids in the area. l
- 3. VENTILATION PARAMETERS There are four doors which enter the area. All doors measure 3' wide by 7' high. Two doors are located on the south wall, one door on the east wall
/]
L/ and one door on the north wall.
- 4. CASES EXAMINED Three cases were examined. Case number one considered all cables in the area burning simultaneously with one door open. Case number two Considered
~
all cables burning simultaneously with two doors open. Case number three considered all cables burning simultaneously with three doors open.
- 5. RESULTS Case number one considered all cables burning simJitaneously with a 3' x 7' l.
l do'or open.- This resulted in a ventilation controlled fire with a heat out-l put of 4504 kW, and a duratien of_95 minutes. The gas temperature at this time would be 814"F which is below the critical temperature of the struc-l tural steel (see Attachment B). Case number two cnnsidered all cables burning simultaneously with two 3' x 7' doors open. This resulted in a ventilation controlled fire with a heat output of 9008 kW and a duratjon of 46 minutes. The gas temperature at this , v 12 - 1
time .would be 1065*F which is below the critical temperature of the struc-V l tural steel (see Attachment B). Case number three considered all cables burning simultaneously with three 3' x 7' doors open. This resulted in a fuel controlled fire with a heat output of 12,078 kW and a duration of 3.5 lbs/'t2 4 .1 lbs = 35' minutes, min /ft2 The gas temperature at this time would be 1203*F which is above the criti-cal temperature of the structural steel (see AttachrNnt! B).
' ~
The position of cable trays relative to structural steel members were
~
!- examined throughout the area in order to assess the potential for localized heating. Cable tray ICCTA is' located within 12 inches of mcaber types
'W30X99, W33X152, W27X84, W24X76, W24X68, W27X114, W21X44, and W21X55.
Attachment C contains the results of calculations performed to determine the response of the ' structural steel membersNto localized heating. These (] calculations are conservative because they assurre that the entire length of the structural steel member is subjected to"1300*F when, in actuality, only a small section of the steel woulds be subjected to Iccalized heating. As can be seen from the results, member types W30X99, W27X84, W24X76, W24X68, W27X114, W21X44 and W21X55 exceeded the localized t'ailure *.emperature of 1100*F during the 35 minute exposure period (time' required for tray to burn to completion). Columns in the area are'W14X730. When exposed to plume. temperatures of 1500*F for 35 minutes, the steel tempes ature does not exceed 500"F.
- 6. EFFECT OF TRANSIENT COMBUSTIBLES 7 The fire examined was fuel controlled,with a' duration of 35 minutes. The temperature at this time exceeded.1100*F, therefore, no transient materials were quantified.

- 1. AREA DESCRIPTION The area under consideration is the Cooling Water Heat Exchanger Area Room 207 on the 201' elevation of the Unit 1 Reactor Building (Fire Area 41).
The bounding walls of the area are of reinforced concrete construction with dn average thickness of 3 ft. The total surface area for heat transfer is 8985 ft 2 (see Attachment A for sketch and calculation of surface areas).
- 2. COMBUSTIBLE LOADING Combustible loading in this area consists of cable insulation located in cable trays. The total surface area of cable trays is 102 ft2 with an average combustible loading of 3.5 lbs/ft2 of cable tray surface area.
There are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS There are two doors which enter this area. Both measure 3' wide by 7' high.
One door is located in the east wall and the other is located in the west
~5 wall and enters stair No. 2.
(G
- 4. CASES EXAMINED Two cases were examined, each assuming that all the cable trays in the area
.were burning simultaneously. Case number one assumed one door open while case number two assumed both doors open.
- 5. RESULTS Case number one assumed all . cables burning simultaneously with one 3' x 7' door open. This 'resulted in a ventilation controlled fire with a burning rate of 4504 kW and a duration of 90 minutes. The gas temperature at this time would be 781*F which is below the critical temperature of the struc-tural steel.(see Attachment B).
( Case number two essumed all cables burning simultaneously with both 3' x 7' doors open. This resulted in a ventilation controlled fire with a burning
' rate of 9008 kW and a duration of 45 minutes. The gas temperature at this l

n The position of cable trays relative to structural members were examined D throughout the area in order to assess the potential for localized heating. Cable tray 10CQA is located within 12 inches of member types W27X84, W21X44, W13X40 and W27X102. Attachment C contains the results of calculations performed to determine the response of the structural steel members to localized heating. These calculations are conservative because they assume that the entire length of the structural steel member is subjected to a temperature of 1300*F when, in actuality, only a small section of the steel would be subjected to localized heating. As can be seen from the results, member types W18X40, W21X44, W27X84 and W27X102 exceeded the single point failure temperature of 1100*F during the 35 minute exposure period (time required for tray to burn to completion). Columns in this area are W14X342 and W14X550. When exposed to a plume temperature of 1500*F, the steel temperature of the W14X342 reaches 1000*F in 55 minutes and the steel temperature of the W14X550 reaches 876 F in 65 minutes.
- 6. EFFECTS OF TRANSIENT COMBUSTIBLES
.The fire examined was ventilation controlled with a duration of 45 minutes. The temperature at this time was 1028"F. Since this temperature approaches the critical temperature of 1100 F, no transient materials were
- quanti fled.
The ceiling height in the area is 12 feet. This distance is measured from
, the floor slab to the bottom of the largest structural steel member in the area which is a W33X141.
The heat release-rates from transient combustibles in the area necessary to reach plume temperature of 1100"F,1300*F and 1500 F at the bottom flange of the beam are listed in the table below. For temperatures greater than 1100*F, the time required to heat the steel to 1100*F are also listed.

- 1. AREA DESCRIPTION The area under consideration is the Main Steam and Feedwater Pipe Tunnel on the 253' elevation of the Unit 1 Reactor Building (Fire Area 46). The bound-ing walls in the area are of reinforced concrete with an average thickness of 3.5 feet. The total surface area for heat transfer is approximately 5858 ft 2.
(See Attachment A for a sketch of the area under consideration and a calculation of areas).
- 2. COMBUSTIBLE LOADING All cabling in this area is routed in conduit, there are no cable trays.
Tne.re are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS There is one 3' wide by 5'10" high door serving this area.
4
- 4. CASES EXAMINED With no exposed combustible cabling and no combustible liquids in the area, there is no fuel in the area to support a fire.
- 5. RESULTS The structural steel in this area will not fail due to a fire as there are no fixed combustibles in the area to support a fire.
' ' 6. -EFFECTS OF TRANSIENT COMBUSTIBLES This area has no fixed combustibles. There is one door measuring 3' wide by 5'10" high entering this area. This corresponds to a ventilation controlled I heat output of 3417 kW. A fire of this heat rate could burn for a maximum of 200 minutes without reaching a temperature of 1100*F. Plume effects from floor level transients are negligible because of the high ceiling. p

- 1. AREA DESCRIPTION The area under consideration is the general floor area on the 217' ele-vation of the Unit 1 Reactor Building (Fire Area 44). The heaviest com-bustible loading encountered on this elevation is found in the northeast corner. The area of-heaviest combustible loading is bounded by column lines 19.4 & 23 and J & Fb (see Attachment A for a sketch of the area under consideration). The bounding walls in the area are of reinforced concrete with an average thickness of 3 f t. The total surface area for heat transfer is 11,309 ft2 (see Attachment A for calculation of areas).
- 2. COMBUSTIBLE LOADING The heaviest concentration'of cabling found within this area was cen-tered along column line 21.5. The average combustible loading of the cable trays in this area is 3.2 lb/f t2 of tray surface area. There are no combustible liquids in this area. Enclosed combustibles are not included in the combustible loading.
tb
- 3. VENTILATION PARAMETERS The area under consideration is open to the remainder of this elevation on its south side. This opening is approximately 13 ft. wide by 35 ft.
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 f t per hour. The fire will spread along all of the horizontal cable trays intersecting the point source for a distance of 5 feet in each direction before the original point source dies out af ter 32 minutes. A maximum surface area of 186 ft2 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 3284 kW.
This heat output is assumed constant throughout the fire duration. The actual heat output as the fire spreads out of the area originally (w.j' . involved would be less since the quantity of cabling that would be
. involved at any one time would be less, 16 - 1

- 5. RESULTS The fire duration was taken to be 180 minutes and the fire temperature
, reached af ter 3 hours was 650*F which is below the critical temperature l for the structural steel (see Attachment C for results of analysis). Since the fire was assumed to occur in the area of heaviest combustible loading, the results are considered to be representative for the entire general floor area on the 217' elevation of the Reactor Building. The location of cable trays relative to structural steel members were examined throughout the 217' elevation of the 1 ~:'etor Building in order to assess the potential for localized heating. A stack of 4 cable trays were positioned 2'6" below a G7 girder so as to presciit a localized heating exposure to structural steel. When exposed to the 1300"F pb.ne temperature for 32 minutes the girder Will be heated to 700*F. Columns in the area are W14X550 and W14X287. When exposed to a plume temperature of 1500*F, the steel temperatures of the columns are as follows: W14X550 876*F after 65 minutes W14X287 1000*F after 47 minutes C. EFFECTS OF TRANSIENT COMBUSTIBLES The fire examined was fuel controlled with a duration of 180 minutes. The temperature at this time was below 1100*F. The maximum additional heat release rate due to transient materials -in the area which will result in an area temperature less than 1100 F is listed below. Fire Duration 0/A(kW/m2) 0 (kW) 3 hours 6.5 3547 The ceiling height in the area is 30 feet. This distance is measured
- from the floor _ slab to the bottom of the largest structural steel member in the area which is a G7.48".

- 1. AREA DESCRIPTION The area under consideration is .he Southeast Corner of the General Floor Area on the 217' elevation of the Unit 1 Reactor Building (Fire Area 44).
Bounding walls are of reinforced concrete construction with an average thickness of 2 ft. The total surface area for heat transfer is 7722 ft2 (see Attachment A for sketch and calculation of surface areas).
- 2. COMBUSTIBLE' LOADING The heaviest concentration of cabling found within this area is along the east wall which borders the railroad bay where cable trays are stacked four high. The average combustible loading of the cable trays in this area is 3.5 lbs/ft2 of cable tray surface area. There are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS The area under consideration is open to the remainder of the 217' elevation of.the' Reactor Building.
(-
- 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 feet per hour. The fire will spread along all of the horizontal cable trays intersecting the point source for a dis-tance of 6 feet in each direction before the original point source dies out after 35 minutes. A maximum surface area of 96 ft2 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 1700 kW. This heat output is assumed con-stant throughout the fire duration. The actual heat cutput as the fire spreads out of the area originally involved would be less since the quanti-ty of cabling that would be involved at any one time would be less.

() The fire duration was taken to be 180 minutes and the gas temperature reached af ter 3 hours would be 550*F which is below the critical tempera-ture for the structural steel (see Attachment C). The location of cable trays relative to structural steel members were examined throughout the area in order to assess the potential for localized heating. A stack of 4 cable trays were positioned 2' below the W27X84 beams 50 as to present a localized heating exposure to the structural steel.
- 6. EFFECT OF TRANSIENT COMBUSTIBLES The fire examined was fuel controlled with a duration of 180 minutes. The temperature at this time was below 1100*F. The maximum additional heat release rate due to transient materials in the area which will result in an area temperature less than 1100*F is listed below.

LIMERICK GENERATING STATION (/
- 1. AREA DESCRIPTION The area under consideration is the general floor area on the 253' ele-vation of the Unit 1 Reactor Building (Fire Area 45A). The heaviest combustible loading encountered on this elevation is found in the CR0 Hydraulic Equipment Area and Neutron Monitoring System Area. The area of heaviest combustible inading is bounded by column lines 19.4 & 23
. and J &_ Fa (see Attachment A for a sketch of the area under considera-tion). The total surface area for heat transfer is approximately 11,774 f t2. The bounding walls are constructed of reinforced concrete with an average thickness of 1.5 ft.
- 2. COMBUSTIBLE LOADING The heaviest concentration of cabling found within this area was along the east wall. The average combustible loading of the cable trays in this area is 4.7 lbs/ft2 of tray surface area. There are no combustible liquids in this area. Enclosed combustibles are not included in the (q/ combustible loading.
- 3. VENTILATION PARAMETERS The area under consideration is open to the remainder of this elevation on its south side. This opening is approximately 28.5 ft. wide and 29 ft. 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 feet per hour. The fire will spread nceth and-south along the east wall and westward 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 386 ft2 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 6816 kW. This heat output is assumed constant throughout the fire duration.
A ( ). The actual heat output as the fire spreads out of the area originally
' involved would be less since the quantity o,f cabling involved at any one time would be less.

- 5. RESULTS The fire duration was taken to be 180 minutes and the fire. temperature reached af ter 3 hours was 1045'F which is bel'w o the critical tempera-l ture for the structural steel (see Attachment C for results of alaly-sis). Since the fire is assumed ,to occur in the a(ea of heaviest combustible loading, the results are considered to be representative for the entire -general floor area on the 253' elevation of the Reactor Building.
The positions of cable trays relative to structural -steel members were examined throughout the 253' elevation of the Reactor Building in order to assess the potential for localized heating. Cable tray 1ACYC05 is located 12" below the bottom of a girdea type'G-52 (54WF366). Attachment D contains the results of. calculations performed to deter-mine the' response of the girder to . localized heating. These calcula-tions are conservative because they assume that the entire length of j l v the girder. is subjected to a temperature of 1300*F when in actuality only a small section of the steel would.be subjected to localized heat-ing. As can be seen from the results, the girder does not reach its l single point. failure temperature of 1100*F during the 50 minute expo-sure. period (time required for a tray .to burn to completion). Columns in the area are W14X730, W14X665, W14X370, W14X550 W14X119 W14X342, and W14X87. When ' exposed to a plume temperature of 1500*F, the steel temperatures of the columns are as follows: J W14X730 J57'F after 65 minutes W14X665 795'F after 65 minutes W14X370 1000*F after 58 minutes W14X550 876*F after 65 minutes W14X119 1000*F after 20 minutes l W14X342 ~ 1000*F af ter 55 minutes W14X87 1000*F after 14 minutes h 19 - 2
- 6. E_FFECTS OF TRANSIENT COMB'JSTIBLES The fire-examined was fuel controlled with a duration of 180 minutes.
The temperature at this time was 1045*F Since this temperature. approaches the critical temperature of 1100*F, no transient materials were quantified. The-ceiling height in the area is 24 feet. This distance is measured
. from the floor slab to the botto., of the largest structural steel
. member in the area wh'ich is a A52, 54". .
'The heat release rate's from, transient combustibles in the area necessary to reach plume temperature of 1100*F,1300*F and 1500*F'at the bottom- flange of the beam are listed in the table below. For temperatures greater than 1100*F, the time required to heat the steel
- ,to 1100*F are also listed.

/~ LIMERICK GENERATING STATION
- 1. AREA DESCRIPTION The area under consideration is the general floor area on the 283' eleva-tion of the Unit 1 Reactor Building (Fire Area 47A). The heaviest combusti-ble loading encountered on this elevation is found in the northeast corner.
The area of heaviest combustible loading is bounded by column lines 20 & 23 and J & H (see Attachment A for sketch of area). Bounding walls are of reinforced concrete construction with an average thickness of 3 f t. Total 2 surface area for heat transfer is 6947 ft (645 m2) (see Attachment A for calculation of areas).
- 2. COMBUST!BLE LOADING The heaviest concentration of cabling found within this area is located five feet to the west of column line 21.5. The average combustible loading of the cable trays in this area is 4 lbs/f t2 of tray surface area. There are no combustible liquids in this area. Enclosed combustibles are not included in the combustible loading.
O 3. VENTILATION PARAMETERS The area under consideration is open to the remainder of this elevation on its. south side, however,- there are several rooms at floor level that extend a height of 12 f t from the floor. This leaves a ventilation opening above these rooms approximately 54' wide by 17' 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 feet per hour. The fire is assumed to extend along the north wall and southwest, a distance of 7 feet before the original point source dies out after 40 minutes. A maximum surface area of 172 ft2 of cable trays (see Attachment 8 for list of cable trays initial 1y burning) will be involved at any one time, which corresponds to a heat output of approximately 3050 kW. This heat output is assumed constant throughout the fire duration. The actual heat output as the fire spreads (J out of the ' area originally involved would be less because concentrations of cabling that would be involved at any one time would be less.
20 - 1 m
l O s assutTs The fire was assumed to last 3 hours with no action takcq by plant per-sonnel to extinguish the fire. The peak gas temperature reached was 854*F (see Attachment C) which is below the critical temperature for the structural steel. Since the fire was assumed to occur in the area of heaviest combustible lo'ading, the results are considered to be representative for the entire general floor area on the 283' elevation of the Reactor Building. The position of cable trays relative to structural steel members were examined throughout the 283' elevation of the Reactor Building in order to assess the potential for localized heating. Cable trays were encoun-tered within 1 foot of type 36WF230 beams in numerous locations. Ca51e trays ICCRA, ICCTA, IMI AB, and 1ACYA were positioned 12 inches below a 18WF45 beam located northeast of the drywell near column line 20. Attachment D contains the results of calculations performed to deter-mine the response of the structural members to localized heating. { These calculations are conservative because they assume that the entire length of the member is subjected to a temperature of 1300*F when in actuality only a small section of the steel would be subjected to localized heating. As can be seen from the results, member type 18WF45 exceeded the single point failure temperature of 1100*F during the 40 minute exposure period (time required for a tray to burn to comple-tion). Attachment D includes a sketch showing the location of the structural member which will fail due to localized heating ef fects. Columns in the area are W14X730, W14X665, and W14X87. When exposed to a plume temperature of 1500*F, the steel temperatures are as follows: W14X730 757*F after 65 minutes W14X665 795*F after 65 minutes W14X87 1000*F after 14 cinutes (O

- 1. AREA DESCRIPTION The area under consideration is the Pipe Chase Service Area, Room 523, on the 295'-3" elevation of the Unit 1 Reactor Building. Bounding walls are of reinforced concrete construction. The average wall thickness is 3.5 ft.
The total surface area for heat transfer is 1742 ft2 (see Attachment A for sketch and calculation of surface areas).
- 2. COMBUSTIBLE LOADING Combustible loading in this area consists of cable insulation in cable trays. The total surface area of the cable trays is 104 ft2 with an average combustible loading of 4.0 lbs/ft2 of cable tray surface area. There are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS One door located in the west wall and measuring 3' wide by 7' high enters this area.
O v
- 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 feet per hour. The fire will spread along all of the horizontal cable trays intersecting the point source for a dis-tance of 7 feet in each direction before the original point source dies out after 40 minutes. A maximum surface area of 104 f t2 of cable trays (see 4
Attachment B for a list of trays) will be involved at any one time, which corresponds to a heat output of 1836 kW. This heat output is assumed con-stant throughout the fire duration. The actual heat output as the fire
. spreads out of the area originally involved would be less since the quanti-ty of cabling that would be involved at any one time would be less.
- 5. RESULTS The case examined assumed one 3' x 7' door open with a spreading cable
- fi re. This resulted in a fuel controlled fire with a heat output of 1836 21 - 1 m_
kW and a duration of 40 minutes. The gas temperature at this time would be
~1035*F which is below the critical temperature of the structural steel (see l Attachment C for results of analysis).
The location of cable trays relative to structural steel members was examined in the area to assess the potential for localized heating. Cable trays were positioned 16 inches below structural steel members of type W18X45. Attachment 0 contains the result of the calculation performed to deter-mine the response of the structural steel to localized heating. These calculations are conservative because they assume that the entire length of the structural steel member is subjected to 1300 F when, in actuality, only a small section of the steel would be subjected to localized heating. As can be seen from the results, member type W18X45 exceeded the single point failure temperature of 1100*F during the 40 minute exposure period (time required for tray to burn to completion).
- 6. EFFECT OF TRANSIENT COMBUSTIBLES The fire examined was fuel controlled with a duration of 40 minutes. The temperature at this time was 1035*F. Since this temperature approaches the critical temperature of 1100*F, no transient materials were quantified.
The ceiling height in the area is 14'9". This distance is measured from the floor slab to the bottom of the largest structural steel member in the area, which is a W18X45. The heat release rates from transient combustibles in the area necessary to reach plume temperature of 1100*F,1300*F and 1500*F at th? bottom flange of the beam are listed in the table below. For temperatures greater than 1100*F, the time required to heat the steel to 1100*F are also listed. T (*F) 0 (kW) Time to 1100*F (min) 1100 5,800 1300 8,436 19 min 1500 9,279 13 min l I) 21 - 2

- 1. AREA DESCRIPTION The area under consideration is the Laydown Area, Room 601, on the 313' elevation of the Unit 1 Reactor Building (Fire Area 48A). The bounding walls of the area are of reinforced concrete construction with an average thickness of 3 ft. The total surface area for heat transfer is 5136 f t2 (see Attachment A for sketch and calculation of surface areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of the cable insulation in a single cable tray which runs north / south through the area. The total sur-face area of the cable tray is 90 ft2 with an average combustible loading of 4 lbs/ft2 of cable tray surface, area. There are no combustible liquids in the area.
- 3. VENTILATION PARAMETERS This area is open to the remainder of the 313' elevation of the Reactor G Building.
U 4 CASES EXAMINED With the light combustible loading in the area, the assumption that all cable trays are burning simultaneously ~ would present the worst case. With all cables burning, a surface area of 90 ft2 would be involved. This cor-responds to a heat output of approximately 1600kW. With all combustibles burning simultaneously, the fire duration would be 4 lbs/ft2 ; ,1 1hs . 40 minutes. min ft2

, is 164 ft2 with an averagi: combustible loading of 3.5 lbs/ft2 of cable tray surface area. There are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS This area is open to the remainder of the 313' elevation by two large walk-
. ways in the south wall.
O _4 . _ CASES EXAMINED With the light combustible loading in this area, the assumption that all
-cables are burning simultaneously would present the worst case. With all cable trays burning a surface area of 164 f t2 would be involved. This corresponds to a heat output'of approximately 2900 kW. With all cables assumed to be burning' simultaneously the duration of the fire would be 3.5 lbs/ft2 + .1 lbs = 35 minutes.

l .= LIMERICK GENERATING STATION 1.. AREA DESCRIPTION The area under consideration is the Backwash Receiving Tank Room 163 on the 180' elevation of the Control Structure (Fire Area 1G) (see Attachment A for. sketch of area). ;?.e bounding walls in the area are of reinforced concrete construction with an average thickness of 2 ft. The total surface area for heat transfer is approximately 2772 ft2 (257 m2) (see Attachment A for calculation of areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of two cable trays which run east-west across the room. The total surface area of the trays is 164 f t2 . The average combustible loading of the trays is 3.5 lbs/ft2 of tray surface area. There are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS There is one door leading into' this area. The door measures P wide by 7'
~
high and is located in the northwest corner of the roon.
- 4. CASES EXAMINED With .the light combustible loading in the area, the assumption that all
. cables are burning simultaneously would present the worst case. With all cable trays burning, 3 surface area of 164 ft2 would be involved. This corresponds to a heat output .of approximately 2900 kW. With all cables assumed to be burning simultaneously the duration of the fire would be 3.5 lbs/ft2 4 .1 lbs = 35 minutes min /ft2 5.. RESULTS.
With all cable trays in the area burning simultaneously and the door enter-ing the area open, a fire temperature of 1002*F was achieved af ter 35 min-utes, which is below the critical temperature '9r the structural ' steel (see Attachment B). None of the ' cable trays in the area was positioned so as to present a localized heating exposure to the structural steel. 31 - 1 l
r'3 6. EFFECTS OF TRANSIENT COMBUSTIBLES
'l The fire examined was foal controlled with a duration of 35 minutes. The tenperature at this time was 1002*F. Since this temperature approaches the critical temperature of 1100 F, no transient materials were quantified.
The ceiling height in the area is 16 feet. This distance is measured from the floor slab to the bottom of the largest structural steel member in the area which is a W24X110. The heat release rates from transient Combustibles in the area necessary to reach plume temperature of 1100*F,1300*F and 1500*F at the bottom flange of the beam are listed in the table below.

- 1. AREA DESCRIPTION The area under consideration is the West Chiller Equipment Room, Room 258, on the 200' elevation of the Control Structure (Fire Area IL). The bound-ing walls of the room are of reinforced concrete and concrete masonry unit construction with an average thickness of 2.5 ft. The total surface area for heat transfer is 5944 ft2 (see Attachment A for sketch and surface area calculations).
-2. COMBUSTIBLE LOADING Combustible loading in this area consists of cable insulation in cable trays. The total surface area of the cable. trays is 195 ft2 with an average combustible loading of 2 lbs/ft2 of cable tray surface area. There are no combustible liquids in this area.
-3. VENTILATION PARAMETERS There are four doors which enter the area. Two of the doors are double doors, each measuring 8' high by 10' wide. One door is located in the west wall while the other door is located in the east wall. The remaining two doors are 3' wide by 7';high. These are -both located in the north wall of the room.
- 4. ' CASES LXAMINED With the light combustible loading in this area, the assumption that ail cables are burning simultaneously would present the worst case. With all cable trays burning, a surface area of 195 ft2 would be involved. This corresponds to a heat output of approximately 3446 kW. With all cables assumed to be burning simultaneously, the duration of the fire would be 2.0 lbs/ft2 + .1 lbs = 20 minutes.
min /ft2
- 5. RESULTS With all the cable trays in the area burning simultaneously and one 3' x 7' door open, the resulting fire was fuel controlled. ~ A gas temperature of
~
689'F was achieved after 20 minutes, which is below the critical tempera-ture for the structural steel .(see Attachment .8). Since the fire was fuel 34 - 1 1 ' -- -
controlled with only one door open, the opening of additional doors into I) the area will not effect the burn rate or final gas temperature. The location of cable trays relative to structural steel members w3s examined in the area. Cable tray 10CNF is located within 12 inches below the bottom of a W36X300 steel member. Attachment C contains the results of calculations performed to determine the response of the steel member to localized heating. These calculations are conservative because they assume that the entire length of the steel member is subjected to a temperature of 1300*F when in actuality only a small section of the steel would be subjected to localized heating. As can be seen from the results the member does not exceed the single point fail-ure temperature of 1100*F during the 20 minute exposure period (time required for tray to burn to completion).
- 6. EFFECTS OF TRANSIENT COMBUSTIBLES The fire examined was fuel controlled with a duration of 20 minutes. The
[) temperature at this time was below 1100*F. The maximum additional heat release rate due to transient materials in the area which will result in an area temperature less than 1100*F is listed below.

- 1. AREA DESCRIPTION The area under consideration is the East Chiller Equipment Room, Room 263, on the 200' elevation of the Control Structure (Fire Area IM). The boand-ing walls of the room are of reinforced concrete and concrete masonry unit construction with an average thickness of 2.5 ft. The total surface area for heat transfer is 4872 ft2 (see Attachment A for sketch and surface area calculations).
.i. COMBUSTIBLE LOADING Combustible loading in this area consists of cable insulation in cable trays. The total sur. face area of the cable trays is 160 ft2 with an average combustible loading of 2.0 lbs/ft2 of cable tray surface area. There are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS There are t.ree doors which enter the area. Two of the doors are double
() v doors, each measuring 8' high by 10' wide. One door is located in the east wall while the other door is located in the west wall. The third door is 3' wide by 7' high and is located in the north wall.
- 4. CASES EXAMINED With the light combustible loading in this area, the assumption that all cables are burning simultaneously would present the worst case. With all cable trays burning, a surface area of 160 ft2 would be involved. This corresponds to a heat output of approximately 2828 kW. With all cables assumed to be burning simultaneously, the duration of the fire wo'Jld be 2.0 lbs/ft2 4 .1 lbs = 20 minutes, min /ft2 s 5. RESULTS With all the. cable trays.in the area burning simultaneously and one 3' x 7' door open, the resulting fire was fuel controlled. A gas temperaturs of 689'F was achieved af ter 20 minutes, which is below the cr#tical tempera-ture for the structural steel (see Attachment B). Since the fire was fuel V

controlled with only one door ven, the opening of additional doors into
-\
the area will not ef fect the burn rate or final gas temperature. The location of cable trays relative to struct, ural steel members was examined in the area. No cable trays were positioned so as to present a
' localized heating exposure to the structural steel.
- 6. EFFECTS OF TRANSIENT COMBUSTIBLES The fire examined was fuel controlled with a duration of 20 minutes. The temperature at this time was below 1100*F. The maximum additional heat release rate due to transient materials in the area which will result in an area temperature less than 1100 F is listed below.

- 1. ARE A DESCR1rTION The area under consideration is the switchgear area on the 217' eleva-tien of the Control Structure (Fire Area 2) (see Attachment A for sketch of area). Bounding walls are of reinforced concrete construction with an average thickness of 3 f t. Total surface area for heat transfer is approximately 13,836 ft2 (1285 m2) (see Attachment A for calculation ofareas).
- 2. COMBUSTIBLE LOADING Combustible loading in this area consists of cable trays which are stacked three high along the south wall of the room. At three locations the cable trays are joined by several vertical cable trays. These three areas are located at the east side, center, and west side of the so.th wall ano represent the areas of heaviest combustible loading. The aver-
, age combustible loading of the cable trays in this area is 3.5 lbs/f t2 of tray surface area. There are no combustible liquids in this area.
- 3. VENTILATION PARAMETERS
~. Tnree sets of double doors serve this area. Each set has 2 leaves.
The door leaves located in the east and west walls each measure 4' wice by 10' high. The door leaves in the north wall measure 5' wide by 11' high.
- 4. CASES EXAMINED Two cases were examined each with a different ventilation parameter and a dif ferent quantity of cable assumed to be burning.
Case number 1 assumed a spreading cable fire in the center area of cable trays along the south wall, with oae c' wide by 10' high door open. Tha fire is assumed to start at a point source and spread horizontally along the cable trays in each direction at a rate of 10 feat per hour. The fire will sprecd east and west along the south wall, a distance of 6 feet in each direction along the cable trays before the original point source dies out after 35 minutes. A maximn surf ace area of g6 (3 G' 37 , 3
ft ? of cable trays (see Attachment B for a list of cable trays) will be V involved at any one time, which corresponds to a heat output of 1700 kW. Tnis heat output is assumed constant throughout the fire duration. The actual heat cutput as the fire spreads out of the area originally involved at any one time would be less since the quantity of cabling that would be involved at any one time would be less. Case number 2 assumed all exposed combustibles in the room burning l simultanscusly with one 4' wide by 10' high door open. The heat output of this fire would be 10,254 kW and would last for approximately 150 minutes.
- 5. RESULTS Case number I resulted in a fire temperature of 395'F when the fire l
duration was taken to 180 minutes. This temperature is below the criti-cal temperature for the structural steel (see Attachment C for results
.of analysis). This fire was fuel controlled, therefore having addi-tional door leaves open would not change the results.
(D V Case number 2 resulted in a fire te aperature of 1188'F at 150 minutes. l This temperature is above the critical temperature for the structural steel (see Attachment C for results of analysis). Since the fires evaluated were assumed to occur in the area of heaviest combustible loading, the results are considered to be representative for the entire switchgear area on the 217' elevation of the Control Structure. 37 - 2 O - U s

s (), The position of cable trays relative to structural steel members were examined throughout the 217' elevation of the Control Structure to assess the potential for localized heating. Cable trays 21CQA and 11CQA are located 12 inches below the bottom of structural steel members of the following types: G1 (W42X316), W36X230, W36X245, W3SX260, W36X300, W33X118,-W30X99, and W27X84. Attachment D contains the results of the calculations performed to determine the response of the- structural steel to localized heating. The exposure time was taken to be 35 minutes which is the time required for the tray to burn to completion. These calculations are conservative because they assume that the entire length of the member is subjected to a temperature of 1300*F when in actuality only a small section of the steel would be subjected to localized heating. As can be seen from the results, the member types G1 (W42X316), W36X230, W36X245, W36X260, and W35X300 will not reach their critical temperature during the' 35 minute exposure period. Member types W33X118, W30X99, and W27X84 will /9 exceed the single point failure temperature of 1100*F within the expo-Nm s/ ,sure period. Attachment D includes a sketch of the structural members which will fail due to localized heating.
- 6. EFFECTS OF TRANSIENT COMBUSTIBLES Since case 2 is a ventilation controlled fire, no transient combusti-bles were quantified for area effects.
The ceiling height in the area is 17'10-1/2". This distance is measured from the floor slab to the bottom of a typical W36 beam. The heat release rates from transient combustibles in the area necessary to reach plume temperatures of 1100*F,1300*F and 1500*F at 17'10-1/2 ' above the floor area listed in the table below. For temperatures greater than 1100*F, the tima required to heat the steel to 1100*F are also listed.

LIMERICK GENERATING STATION
- 1. AREA DESCRIPTION The area under consideration is the Fan Room on the 304' elevation of the Control Structure (Fire Area'27). The bounding walls in the area are of reinforced concrete with an average thickness of 2 ft. The total surface area for heat transfer is 17,071 f t2 (see Attachment A for sketch and calculation of areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of cable insulation located in cable trays. Total cable tray surface area is 748 ft 2. The average combustib,le loading of the cable trays is 3.6 lbs/ft2 of tray surface area.
There are no combustible liquids in this area. Enclosed combustibles are not included in the combustible loading.
- 3. VENTILATION PARAMETERS -
Five doors serve this area, four measuring 3' x 7' and one measuring 9' x 10'. Two 3' x 7' doors are located in the north wall, one is located in the east wall while the fourth door is located in the west wall. The 9' x 10' door is also located in the west wall.
- 4. CASES EXAMINED With_the light combustible loading in this area, the assumption that all cables are burning simultaneously would present the worst case. With all cable trays burning, a surface area of 748 ft2 would be involved (see Attachment B for a list of trays). Three cases were examined; the first case involving a ventilation opening of 21 ft2 , one 3' x 7' door open. The second case' examined involved a ventilation opening of 422ft , two 3' x 7' doors open. The third case examined involved a ventilation opening of 63 ft 2, three 3' x 7' doors open.
- 5. RESULTS For the three cases examined, all cable trays in the area are burning simultaneously. In the first case, a gas temperature of 557*F was achieved after 105 minutes. In the second case, a gas temperature of 735'F was
{} achieved after 54 minutes, in the third case, a gas temperature of 849'F 38 - 1
ns . U:
~
,-sg was achieved af ter 36 minutes (see Attachment C for results of all three 5--d analysis). All three temperatures are below the critical temperature for the structural steel. The cable trays in the area were positioned so as to not present a localized heating exposure to the structural steel.
- 6. EFFECTS OF TRANSIENT COMBUSTIBLES The fire examined was fuel controlled with a duration of 36 minutes. The-temperature at this time was below 1100 F. The maximum additional heat release rate due to transient materials in the area which will result in an I
area te'mperature less than 1100*F is listed below. Fire Curation Q/A (kW/m2) 0 (kW) 36 min 12.5 6623 The ceiling height in the ares is 24 feet. This distance is measured from the floor slab to the bottom'of the largest structural steel nember in the area which is a 38" girder.

- 1. AREA DESCRIPTION The area under consideration is the diesel generator cell 1 A on the 217' elevation of the Unit 1 Diesel Generator Building (Fire Area 79). (See Attach:aent A for a sketch of the area.) The bounding walls in the area are of reinforced concrete with an average thickness of 2 feet. The total sur-face area for heat transfer is 5579 ft2 (see Attachment A for calculation of areas).
- 2. COMBUSTIBLE LOADING Combustible loading in the area consists of 198 ft2 of cable tray, 250 gallons of lubricating oil, and 800 gallons of fuel oil which is assumed to have leaked into the diesel generator cell from a postulated break in t
. fuel oil supply line.
- 3. VENTILATION PARAMETERS Two intake louvers for the diesel generator cell serve this area, each measuring 5.25' high x 6.5' wide. Both loovers are located in the south wall.
'4. CASES EXAMINED The case examined assumes a fuel oil. fire with both louvers serving the area open which results in a ventilation controlled fire with a maximum heat release rate of 12,747 kW. This case assumes that the pre-action l
sprinkler system in the room dces not operate and/or the fire brigade takes no action toward extinguishing the fire.
- 5. . RESULTS As can be seen from the results in Attachment B, th'e critical temperature of the structural steel will be exceeded within 10 minutes. This is due to
{ the large ventilation openings in the area and the large quantity of fuel oil available for combustion. W Q 42 - 1

- 1. AREA DESCRIPTION The area under consideration is the RHRSW Valve Compartment on the 251' elevation of the Spray Pond Pump Structure (Fire Area 122E). The bounding walls of the area are of reinforced concrete construction with an average thickness of 2.5 ft. The total surface area for heat transfer is 1871 f t2
-(see Attachment A for sketch and calculation of surface areas).
- 2. COMBUSTIBLE LOADING
,- Combustible loading in the area consists of the cable insulation in a
. single cable tray. The total surface area of the cable tray is 64 ft2 with an average cumbustible loading of.3 lbs/ft2 of cable tray surface area.
There are 'no combustible liquids in the area.
- 3. VENTILATION PARAMETERC Ventilation to the area is through an open stairwJll which leads to the 268' ele"ation.
- 4. . CASES ET. MINED With the light combustible loading in the area, the assumption that all cables were burning simultaneously would present the worst case. With all cables burning, a cable tray surface area of 64 f t2 would be involved. This c'rresponds to a heat output of 1130 kW. The fire duration with all cables burning would be 3 lbs/f t2 4 .1 lbs = 30 minutes.
min /ft2
- 5. RESULTS ilith all cables-burning simultaneously, a gas temperature of 729*F would be j achieved af ter 30 minutes, which is below the critical temperature of the structural steel (see Attachment B).
The position of the cable tray relative to the structural steel members was examined in the area. The cable tray wis positioned so as to not present a localized heating exposure to the structural steel. (3

Columns Various levels of the Reactor Building contain 14" columns of different Neights. These range from W14X87 for the smallest to W14X730 for the largest. The fire exposure to these columns was evaluated from a fire plume exposure, either from transients or fixed combustibles at the base of the column. The acceptance criteria was that the cross sectional temperature of the column remain below 1000*F. The he?t transfer calculations, as with beams, ignore conductive heat losses along the column.

'Ihe above cccparisons were made on the following bares:
- 1. Average temperature calculation: Sandia Laboratories provided thernoccuple readings and temperature plots for the six full-scale tests conducted by UL. These readings were used to calculate a volumetric average of the 76 thernoccuple locations (Figure 1). In evaluating the data, thernoccuples #26 and 28 were not functioning properly, #56 was not included in the data and #31 and 32 were interchanged. To replace #26 and 28, thernoccuples #102 and 100, respectively, were used (see p.116, IUPEG/CR 3192) . The value for #56 was taken to be the average of adjacent thernocouples #44 and 68.
The test recm was divided into the 76 zones shown on Figure 2. Each of these zones was assigned the temperatures of the thermocouple within the zone. Weighted volumetric averaging was then perforned by using the following formula. N T. x V. 1 1 i=1 =T N ,m y, b i=1 1 Where Vf = Each of the 76 volumes shown on Figure 2 Tf = The therroccuple data for V1 All 76 zones were used in calculating the average rocm temperature. An average temperature for the upper portion of the rocm was calculated by eliminating the lower layer of thermocouples and their associated volumes. The average temperatures were calculated using the peak terperatures frcm the test data.
- 2. Heat Release Rate Heptane - Literature values for heat release rates for flanmable liquid pool fires gegerally and heptane specifically vary in the range of 2500 to 3300 kW/m . For the Sandia and UL tests, the heat release rate was calculated by tak2ng the total heat yalue of the fuel divided by the duration of the fire, and is 1966 kW/m . The table below shows the heat release rate for the heptane fire using this data.

Heat Release Rate for Heptane Pool Fire O Source 913 Mi Sandia/UL - NUREG/CR-3192 1160 Mi Based on 120,000 BTU / gal - Coulbert Fire Technology Aug. 1977 1530 kW FMRC-Alpert & Ward, SFPE-TR 83-2 The methodology used for Limerick for pool fires was based on Coulbert's approach. Therefore, for this emparison, the value of 1160 kW was used. Cables - The heat release rate for the non-qualified PE/PVC was calculated using the mass loss data and heat of embustion similar to the methodology used for Limerick. The Di test data (see EPRI NP-1881) for Pg/PVC was used. This yields a heat release rate of 628 kW/m of cable-tray. In the case of the qualified (IEEE 383) XLPE cables, no large (' scale test data was available similar to that on PE/PVC or hypalon jacket conducted by FMRC. To develop the heat release rate for these cables, the small scale tests outlined in EPRI NP 1200 (see Table S-4) were used as a cmparison to develop a heat release rate. 'Iwo such values were developed. The first was . developed by taking the PE/PVC data frm EPRI NP-1881 and nultiplying by the ratio of small scale heat release rates frm EPRI NP-1200 as follows: 2 628 Mf/m x 475 XLPE = 506 Mi/m frm PE/PVC [ 589 PE/PVC The second was developed by taking the hypalon data and j nultiplying by the ratio of small scale heat release rates as follows: 2 2 190 Mf/m x 475 XLPE = 443 kW/m frm hypalon 204 hypalon l These caparisons yield a range of heat release rates for Test 2 of 1234 kW - 1410 kW. l In the cases where cable protection schemes were provided (i.e., l ceramic fiber insulation or cable coatings) no test data exists regarding heat release rates. To estimate these heat release rates, the duration of the fire for protected cables was campared to that of
-unprotected cables. The heat release rate was then developed by
[) nultiplying the heat release rate of the unprotected cables by the ratios of fire duration. l l l t _ _ _ , . - , _- ~. . . . - . . , _ _ . - , _ _ . .

- 3. Fire duration: The fire duration was determined frcm the thernoccuple readings in the fire plume (Nos. 13, 14, 15, and 16 on Figure 1). When the tenperature of these thermocouples dropped sharply, the fire was assumed to be ccepleted.
+ Sunmary The results of the work undertaken to ccupare the test data of the UL test fires analyzed by Sandia National Iaboratories in NUREG/CR-3192 with the analysis of identical fires using the PECo heat balance nodelindicate that the model predicts temperatures which are higher than the weighted volumetric average tenperatures obtained frcm the test data. tbte that the calculated average temperatures frcm the test data are based on instantaneous maxinum peak values. To perform calculations for these comparisons required that assunptions be made for burn rates and heat releases because no data was available for scme of the materials being burned. The input to the Limerick and-Peach Bottczn calculations have been gathered frcm test data and were not based upon assumptions. The heat balance methodology is not intended for use as a tool for , calculating a precise tcstperature that results frcm a fire. The u intended application is that of a conservative screening device in the , process of determining the surviv@ility of structural steel during a fire. In addition to using the heat balance model to determine overall rocxn or area tenperatures localized effects of fires on the structural steel are evaluated. This is accenplished by looking at the plumes of the hypothesized fires. Cnce tenperatures are obtained frcm these devices steel temperatures are calculated by using the methodology presented by Stanzak as subnitted with our calculations. DMG:mtk 1/13/84-1 ().
