SUBJECT:

Turbine Building Temperature Response to Steam Leaks OBJECTIVE OR PURPOSE:

The purpose of this calculation is to evaluate the temperature response in the Turbine Building to a Main Steam leak. This information will aid in determining the feasibility of increasing the setpoint limit for the turbine building temperature switches (1E31N0361A/B/C/D) that trigger MSIV isolation. It is desired to raise the current setpoint limit of 145°F to 160°F for leak detection temperature detectors 1E31N0361A/B/C/D, in order to avoid nuisance trips during the hot summer months.

Evaluation of the temperature responses at different values of steam line leak rates may also provide the necessary supporting data to help justify a change to the limiting leak rate that the temperature switches are designed to detect.

SCOPE OF CALCULATION/REVISION:

This calculation will re-establish the design basis for the temperature detectors, and supports a justification for selecting a new, higher leak rate value. A new, higher leak rate can be established such that the total mass effluent from the steam line leak would not exceed the total mass release from the main steam line break (141,687 lbm) within two hours. A leak rate that satisfies this criterion would ensure that the 10CFR100 site boundary dose limit is not exceeded.

This calculation will also serve as the basis for the license amendment that will raise the setpoint limit for switches 1E31N0361A/B/C/D to 160°F. The calculation will show that temperature increases to 145°F and 160°F will not result in exceeding the 10CFR100 dose limits at the site boundary.

SUMMARY

OF RESULTS/CONCLUSIONS: The analysis results indicate that neither a 2.9468 Lbm/sec leak, nor a 10.99 Lbm/sec leak, will result in an elevated temperature of 145°F near the E31 temperature detectors for any analyzed condition.

A 19.68 Lbm/sec leak will result in an elevated temperature of 145°F under the required 2 hrs, but not 160°F, for all analyzed conditions. Of the four leak rates, only a 45.11 Lbm/sec leak will result in an elevated temperature of 160°F near the E31 temperature detectors for the analyzed conditions. It does so in less time than the required limit of 52 minutes 21 seconds.

LIMITATIONS OR RESTRICTIONS ON CALCULATION APPLICABILITY:

Evaluations are not performed for any proposed future power uprate conditions.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Analysis Methodology This calculation evaluates the Turbine Building temperature response for four different Main Steam 1

Line (MSL) leak rates (2.9468 Lbm/sec, 10.99 Lbm/sec, 19.68 Lbm/sec, and 45.11 Lbm/sec) using the GOTHIC computer code. The leakage flow rates used in this calculation were chosen to provide a broad range of flows based on parameters of significance to the problem. The flow rates were established based on the following rationale:

2.9468 Lbm/sec This leakage rate is equivalent to the current 25 gpm feedwater line leak that temperature switches 1E31N0361A/B/C/D are intended to detect.

gal ft 3 Lb sec Lb 25 ' 0.13368 ' 52.905 3m ¸ 60 = 2.9468 m min gal ft min sec Note that the density is that of the feedwater at 425°F (DIN 3).

10.99 Lbm/sec (Actual value calculated 10.9847 Lbm/sec)

This leakage flow corresponds to the leakage from an equivalent 1 inch schedule 80 pipe break.

(0.719 square inch opening multiplied by G = 2200 Lbm/sec-ft2 for steam at 1100 psia and 1190.4 2 3 Btu/lbm). Steam conditions are from Figure 3 of DIN 3. The conservative value for G is obtained from the Moody diagram for maximum flow rate (DIN 53). A copy of the Moody Diagram is included as Attachment G. This leak is equivalent to a 93 gpm feedwater line leak.

19.68 Lbm/sec (Actual value calculated 19.6788 Lbm/sec)

This leakage flow corresponds to the integrated break flow released from a main steam line break (141, 687 Lbm) (DIN 52) divided by 7200 seconds (two hours). Two hours is the basis for the 10CFR100 dose calculations. This leak is equivalent to a 167 gpm feedwater line leak.

45.11 Lbm/sec (Actual value calculated 45.1153 Lbm/sec)

This leakage flow corresponds to the leakage from an equivalent 2 inch schedule 80 pipe break (2.953 2

square inch opening times 2200 Lbm/sec-ft2 for 1100 psia steam). GE states that this opening size represents the maximum opening size for which the makeup systems can keep up. Thus, this opening size is defined by GE as not a LOCA (DIN 54). This leak is equivalent to a 383 gpm feedwater line leak.

1 This mass flow value contains a greater number of significant digits as compared to the accompanying flow rate values, because of multiple references to this specific number in other PNPP documents.

2 Enercon is aware that the GE Thermal Kit identified in DIN 3 has been updated to contain the partial arc turbine modification. The latest Kit, 1LA0279, is contained in DI-237 Rev. 2. and gives a pressure of 980.7 psia. For a lower pressure to obtain the same flow rate would require a larger leakage area. This has no effect on the results of this calculation as the assumed leak rates were chosen somewhat arbitrarily in order to represent a range of flows.

3 The Moody Diagram represents homogenous, equilibrium steam-water and, thus, presents lower G values than other publications for 1100 psia steam. The lower G value results in a smaller leak rate, which takes more time to elevate the room temperature.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks The time at each leak rate that would result in a mass release equivalent to the main steam line break is calculated by dividing the mass equivalent of a main steam line break by the particular leak flow rate.

M t=

Q where, t = time required for leak to result in mass release equivalent to the MSLB [seconds]

M = MSLB mass release equivalent of 141, 687 Lbm Q = leak rate [gpm]

This results in the following maximum allowable times for each leak rate:

2.9468 Lbm/sec limit at 48,082 seconds, or 13 hrs 21 minutes 22 seconds 10.99 Lbm/sec limit at 12,893 seconds, or 3 hrs 34 minutes 53 seconds 19.68 Lbm/sec limit at 7200 seconds, or 2 hrs 45.11 Lbm/sec limit at 3141 seconds, or 52 minutes 21 seconds4 Each evaluation will determine the time required to reach 145°F and 160°F at the location of temperature sensors 1E31N0361A/B/C/D. The E31 leak detection thermocouples are located on the East wall at column TB14, approximate elevation 632-feet (GOTHIC sub-volume V7s15). The calculation will contain thirty-six different case runs defined as follows. An individual case run will evaluate the temperature response due to each steam line leak rate occurring at each of the three defined leak locations for three external environmental conditions.

The GOTHIC computer code (Version 7.0) is used to model the Turbine Building. Local effects in the Turbine Building will be addressed by subdividing the volumes into smaller sub-volumes, then assigning the leak location to different sub-volumes. The local temperature in the vicinity of the leak detection thermocouples will then be calculated. The primary zones of interest are Environmental Zone TB-1 (DIN 51) and the underlying floors at the East end of the building. Flow paths with loss coefficients are used to connect various volumes, and the model initialization temperatures reflect steady-state conditions. Attachment A is provided for information to graphically identify the column-lines and elevations in the Turbine Building. A code-generated diagram in Attachment B indicates the basic layout of the Turbine Building GOTHIC model, showing the control volumes, the boundary conditions, and the interconnecting flow paths. The GOTHIC model will also take into account ventilation in the TB-1 Zone, the effect of steel heat sinks on the rate of temperature rise, and the effects of outdoor temperature.

Control Volumes 4

It is understood that this leak rate will result in a mass effluent greater than a MSLB in less than two hours. The purpose of this leak rate is to provide additional information.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Control volumes are the basic building blocks of GOTHIC and are generally used to model individual rooms in a building. Control volumes may be subdivided in situations where buoyancy-induced flow is the primary means of mass transport or, as in this case, a steam line leak is small and there exists the possibility of only localized temperature increases.

The volume of equipment, piping, HVAC ducts, and other components within rooms is not subtracted 5

from the total room volume . The reference elevation is the floor of the control volume. The height is the distance from the floor to the ceiling of the control volume. The hydraulic diameter input for control volumes is defined as follows:

4A DH = , where A is the cross-sectional area and Pw is the wetted perimeter (2*(L+W)).

Pw There are seven subdivided control volumes for the Turbine Building model. The hydraulic diameter is calculated in the horizontal plane. All dimensions are taken from the concrete outline drawings (DIN 12

- 31). Refer to the accompanying isometric sketch (Attachment A) for the control volume layout, subdivision and dimensions.

Control Volume 1 (CV1)

CV1 is the operating floor at elevation 647.5'. This volume stretches the entire length of the turbine building from column TB1 to column TB17.

V = 445.4*115.33*67.2 = 3,452,000 ft3 DH = 4(115.33)(445.4)/2(115.33+445.4) = 183.2 ft6 This volume is subdivided into 24 sub-volumes as indicated on the turbine building isometric sketch (Attachment A). The vertical subdivisions are dimensioned to match several of the control volumes identified below. The horizontal subdivision at elevation 674.5' matches the elevation of the internal walls at columns TB9 and TB13.

Control Volume 2 (CV2)

CV2 extends from column TB1 to TB4. It is physically connected to the building operating deck at elevation 647.5, but it extends down to elevation 620.5' on the West side of the Turbine Building. This volume was subdivided into six sub-volumes.

Preliminary runs of the model indicated that the inclusion of this volume had a negligible effect on the results. Therefore, it was disconnected and subdivisions were removed in order to improve the run 5

The exact volume is not critical to this analysis since air has little heat capacity and pressurization is not an issue.

Additionally, a sensitivity case was run to determine the effect of reducing the Control Volume 7 by 10%, in order to account for piping, equipment, etc. The results were identical to the original run.

6 The hydraulic diameter of the sub-volume channels for all of the Control Volumes is set to 1.0E+06 feet as recommended by the GOTHIC Users Manual (DIN 4).

SUBJECT:

Turbine Building Temperature Response to Steam Leaks times. Note that this volume remains in the model but that all physical data associated with it was not design verified.

Control Volumes 3-7 (CV3 - CV7)

These control volumes compose the area in the Turbine Building under the operating floor between column lines TB9 and TB14. Each control volume selected is an area between two column lines.

These volumes extend from the floor elevation at 577.5' to three feet below the operating floor at 647.5.

CV3 (TB9-TB10)

V = 34.17*115.33*67 = 264,000 ft3 DH = 4(115.33)(34.17)/2(115.33+34.17) = 52.7 ft CV4 (TB10-TB11)

V = 36.75*115.33*67 = 284,000 ft3 DH = 4(115.33)(36.75)/2(115.33+36.75) = 55.7 ft CV5 (TB11-TB12) 3 V = 36.17*115.33*67 = 279,500 ft DH = 4(115.33)(36.17)/2(115.33+36.17) = 55.1 ft CV6 (TB12-TB13)

V = 35.0*115.33*67 = 270,500 ft3 DH = 4(115.33)(35.0)/2(115.33+35.0) = 53.7 ft CV7 (TB13-TB14)

V = 36.75*115.33*67 = 284,000 ft3 DH = 4(115.33)(36.75)/2(115.33+36.75) = 55.7 ft Each of these volumes is subdivided into 18 sub-volumes. The first horizontal subdivision at elevation 589.5' corresponds to the height of the cubicle walls at the bottom of the Turbine Building. The second elevation subdivision at 620.0' is the grade elevation, which also roughly corresponds to the bottom elevation of some of the internal junctions. The internal junctions allow air to flow from one area to another (Floors are at 620 and 624). See Attachment A.

The critical sub-volume of concern is V7s15, which contains the temperature detectors.

Thermal Conductors Above grade at elevation 620 ft (DIN 10), the Turbine Building is treated as though it is conducting with the outside environment. The outdoor temperature used depends on the case being evaluated. Refer to Section Initial Conditions. The heat transfer coefficient of the outside surface vertical walls above 2

grade is set to 1.46 Btu/hr-ft -°F (DIN 1, still air on a vertical non-reflective surface). The heat transfer 2

coefficient of the roof on CV1 is set to 1.63 Btu/hr-ft -°F (DIN 1, still air on horizontal non-reflective surface with heat flowing upwards). The inside surface allows natural convection depending on the slab orientation (vertical, face up, face down). Below grade, the Turbine Building surface walls conduct

SUBJECT:

Turbine Building Temperature Response to Steam Leaks directly with the ground. Ground temperature is set constant at 53°F (see Assumption 6). According to the D-409 series drawings (DIN 12 - 31), the concrete walls, as well as the floor of CV1, are three feet thick and extend from the bottom elevation of the Turbine Building to above grade at Elevation 647.5. This encompasses all of Control Volumes 3 - 7. Control Volume 1, which starts at Elevation 647.5, has steel walls and a steel ceiling. However, for CV1 between Elevations 647.5 and 674.5, there are concrete walls just inside the outside steel walls. Since the concrete is significantly thicker than the steel, these walls are treated solely as concrete. Rigorous accounting of the steel in CV1 is not required. Control Volume 1 lies above Control Volume 7 where the temperature sensors reside.

Any minor changes to the temperature profile above CV7 will not affect the steady state temperature at the thermocouples, because air is being moved up from below the operating floor through forced convection. The areas of the walls and ceiling/roof of CV1 were determined by drawings D-101-017 (DIN 8) and D-101-018 (DIN 9). The areas of the walls and ceiling/floors of CV3 - CV7 were determined by drawings D-409-011 (DIN 12) and D-409-015 (DIN 13). The GOTHIC preprocessor is used to suitably node the concrete and steel slabs. The slabs are sized to match the dimensions shown on the Turbine Building isometric sketch (Attachment A). All wall, floor, and ceiling slabs are spanned across the volume subdivisions, which border the appropriate surface. All conductors are initialized at the same initial temperature of the volume in which they reside.

This model incorporates steel heat sinks as indicated by the D-502 series drawings (DIN 32 - 41, 43 -

46) for the Turbine Building. The total volume and surface area of steel is calculated for each of the control volumes below the operating floor (Control Volumes 3 - 7) in Attachment C. This includes platforms, steel framing, posts, and hangers. A set of spreadsheets displaying the cell formulas are provided in Attachment D.

The steel member type and length for each I-beam, post, and hanger in Control Volumes 3 - 7 was gathered from the D-502 series drawings listed above. Using steel member dimensions determined from the Steel Construction Manual (DIN 2), surface areas and volumes were calculated.

Surface Area [sq.in.] = (4 ' b f + 2 ' d - 2 ' t w ) ' L ' 12 Volume [cu.in.] = [2 ' t f ' b f + (d - 2 ' t f ) ' t w ] ' L ' 12 where, bf, d, tf, and tw are steel member dimensions [in.]

L = length of the steel member [ft]

The platforms are made up of grating that is constructed of 1-1/4 inches by 3/16 inch bearing bars that are spaced 1-3/16 inches center-to-center (DIN 42). To determine the surface area and volume of the platforms, first the area footprint is determined from the D-502 series drawings for Control Volumes 3 -

7

7. Then, assuming the grating consists of only the bearing bars in one direction , the volume and surface area per square foot of grating is calculated using the following method:

L N=

w 'd 7

The steel guide rods are not factored in for conservatism.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks where, N = average number of bars per square foot of grating L = length of bars [inches]

w = width of bars [inches]

d = distance between bars [inches]

There are on an average of 8.7 twelve-inch bars per square foot of grating. This gives a total of 104.4 inches of bar per square foot of grating.

V = LA ' w ' t where, V = volume per square foot of grating [cubic inches]

LA = length of bar per square foot of grating [inches]

w = width of bars [inches]

t = thickness of bearing bars [inches]

Volume equals 24.5 cubic inches per square foot of grating.

VOLUME FACTOR : 24.5 in.3 / 1728 = .0142 feet cubed per square foot of foot print SA = L A ' t ' 2 + L A ' w ' 2 where, SA = surface area per square foot of grating [square inches]

LA = length of bar per square foot of grating [inches]

t = thickness of bearing bars [inches]

w = width of bars [inches]

Surface area equal 300 square inches per square foot of grating. The surface area created by the height x width dimensions are considered negligible for this calculation.

SURFACE AREA FACTOR : 300 in.2 / 144 = 2.083 square feet of surface area per square foot of foot print Based on the total calculated volume and surface area, a steel conductor of appropriate thickness is spanned across each of the control volumes, maintaining a regular distribution across each sub-volume.

Flow Paths (Junctions) and Leak Locations Flow paths are used to connect one volume to another, or to connect a boundary condition with a volume. There are large vertical openings between the lower volumes and large horizontal openings between the lower volumes and the operating deck. The flow areas, which expose multiple sub-volumes of different control volumes, must be broken into multiple flow paths.

The inertia length of a GOTHIC flow path is the center-to-center distance between the connected volumes. For this application, since the flow velocities are relatively small for volume-to-volume flow,

Page 7 of 51 CALCULATION COMPUTATION NOP-CC-3002-01 Rev. 00 CALCULATION NO.: 2.4.6.14 Rev. 0 TITLE /

SUBJECT:

Turbine Building Temperature Response to Steam Leaks the flow path inertia length is approximated at 30 feet for all volume-to-volume connections. The flow path friction length is also non-critical for this application and is set to 1 foot for all flow paths. The flow path friction length only becomes important when the model is concerned with buoyancy and thermally-induced flow. In this case, air movement is driven by forced convection (i.e. the ventilation system).

The forward and reverse loss coefficient for all flow paths is set to 2.78 as recommended by the GOTHIC Users Manual (DIN 4).

Flow Paths 1-6 represent the three large openings in the wall at column-line TB13, which connect Control Volumes 6 and 7. Two junctions are used for each opening because the flow area of each spans two sub-volumes. Preliminary runs indicated that several inches of water would accumulate on the floor of CV7, so Flow Paths 24 and 25 were added to simulate the cubicle wall opening which connects Control Volumes 6 and 7. The dimensions for these flow paths were taken from drawing D-409-086 (DIN 27).

Flow Paths 7-14 represent the large wall openings at the column lines in the Turbine Building below the operating deck. The dimensions for these flow paths are taken from drawings D-409-089 (DIN 28), D-409-092 (DIN 29), and D-409-095 (DIN 30). In some cases, the dimensions of these flow paths have been approximated, and multiple flow paths have been combined into single flow paths. This approach is judged acceptable, since scoping runs indicated that the flow between these volumes would have little effect on the results.

Flow Paths 15 - 20, 26, and 27 are the horizontal openings on the operating deck (EL. 647'-5"). The area of these openings was derived from drawings D-409-029 (DIN 14) and D-409-033 (DIN 15).

Flow Path 21, at the top of the Turbine Building, is the ventilation air exit for the entire building. For modeling purposes, the area of the opening needs to be set large enough to allow the air to be driven to the outside atmosphere via means of BC 1P (see Boundary Conditions below).

Flow Path 22 is the opening in the main steam piping from which the steam leaks into the Turbine Building. The dimensions for this flow path are approximated. The approximation is irrelevant, because the flow, in this case, is driven by the boundary conditions.

Flow Path 23 is the opening of the Auxiliary Building steam tunnel to the Turbine Building. The dimensions for this flow path are taken from drawing D-409-062 (DIN 20).

Flow Paths 28 - 37 represent ventilation openings from the HVAC ducts to Control Volumes 3 - 7.

Each CV has two flow paths. This represents the two main duct lines supplying each control volume.

The discharge locations are combined into a single flow path per sub-volume for the GOTHIC model.

The heights of the discharge locations are averaged for each sub-volume (DIN 47, 48). This is acceptable, because all air is considered homogeneous inside each sub-volume.

The purpose for the leak detection system is to provide a redundant means of detecting and isolating leaks in the primary coolant system (RCS) for BWRs. The system was intended by GE to prevent the escalation of a leak into the design basis accident. For this system, the design basis accident is the full main steam line break (i.e. 28 inch piping break). Therefore, the leak locations correspond to those locations where the full size main steam line piping is located.

Turbine Building Temperature Response to Steam Leaks Drawing D-304-018 (DIN 11) illustrates the main steam piping upstream of the Turbine Stop Valves (TSVs). The steam lines enter the TB from the Steam Tunnel at an approximate elevation of 630', then elbow downward to an approximate elevation of 592. Sloping downward, these 28-inch lines traverse northward to column TB-E, where condensate traps are located. The large pipes elbow again, rising vertically (within about 5-feet of the east wall) to Elevation 635-6. Here they elbow again and enter the TSVs. A Main Steam Line Break (MSLB) could occur in this piping at the lower elevations in the non-zoned region below TB-1.

Based on this, leaks are assumed at three locations:

1) MSLB at 624' near TB14 (east wall) and TBE (Turbine Building centerline between north and south wall)

2) MSLB at 592' near TB14 and TBI (southeast corner)

3) MSLB at 592' near TB13 and TBI (southwest corner)

Location 1 is chosen to determine the effects of ventilation on the thermocouples. Locations 2 and 3 are chosen since they are the farthest from the leak detection thermocouples and therefore represent the worst case from a detection standpoint.

Leaks in piping that are physically closer to the thermocouples are concluded by inspection to be bounded by leaks in these locations. Also, leaks in main steam branch lines are ignored since these leaks could not propagate into the large main steam line break that is the primary focus of this leak detection system.

To further verify that the chosen leak locations are bounding, two additional possible limiting cases were run. Both cases are under Winter (cold) conditions with a 2.9468 Lbm/sec leak rate. These conditions exhibit the most conservative scenario, in which the most amount of steam would need to leak out before raising the room temperature to a specified point. Leak 4 was chosen as the point where the main steam line first enters the Turbine Building from the Steam Tunnel (GOTHIC sub-volume 7Vs18, EL. 630 ft). This location is farthest from the thermocouples at a higher elevation.

Leak 5 was chosen to be located where the Main Steam line elbows up near TBE, directly below the thermocouples (GOTHIC sub-volume 7Vs9, EL. 601.5 ft). This leak would lie directly between the two vents inside their air paths. Since their respective maximum temperatures of 124.2°F and 129.4°F are greater than the maximum temperatures resulting from Leak Locations 1 and 3 under identical conditions, our current leak locations remain the most conservative. Thus, they are bounding.

To aid in maintaining conservatism, all steam leak flow paths were oriented to point in the West direction, away from the thermocouples on the East wall. A directional sensitivity case was run with a mass flow rate of 45.11 Lbm/sec during summer conditions in leak location 3. The sensitivity run indicated that while a break oriented in the East and North directions both resulted in steady state o

temperatures of approximately 200 F, a break oriented in the West direction reached a steady state o

temperature of only 195 F.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Boundary conditions provide a means of communication between the model and known conditions at the boundaries of the model. Thirteen boundary conditions are used for this model.

A pressure boundary condition 1P is connected to the top of the Turbine Building to prevent an unrealistic pressure increase inside the Turbine Building (i.e., simulate leakage to atmosphere). The pressure of this boundary is set slightly lower than atmospheric to allow the Turbine Building lower elevations to remain at atmospheric (considering the static head of air).

A flow boundary condition 2F is used to simulate the main steam line break (MSLB). The flow rate is multiplied by a forcing function to ramp the flow from zero to unity in the first second of the transient in order to prevent numerical problems which could occur if full flow were used at time zero. The following boundary condition values are for 25 gpm flow and were derived from Figure 3 of DIN 3, Original VWO Flow:

MSLB flow = 2.9468 lbm/s, 10.99 lbm/s, 19.68 lbm/s, or 45.11 lbm/s 8

enthalpy = 1190.4 Btu/lbm 9

LVF = 0 10 SPR = 1 Another flow boundary condition 3F is used to inject inlet air from the steam tunnel. Based on drawing B-022-006 (DIN 5), the average air temperature is 121°F (see Assumption 2). The air-flow is 2500 scfm (DIN 46), which converts to 41.67 ft3/s for input to the GOTHIC code.

Fluid boundary conditions 4F - 13F supply ventilation air to Control Volumes 3 - 7, according to the flow rates indicated on drawings D-922-783 (DIN 47) and D-922-784 (DIN 48). Their flow rates are summed together. This is acceptable, because all air is considered homogeneous inside each sub-volume. The ventilation air temperature is considered to be 63°F throughout the year (see Assumption 1).

The fluid pressure in both of these cases is not critical since it is used only to determine fluid density 11 and thus the fluid momentum .

Initial Conditions All volumes are initialized at atmospheric pressure. The initial temperature and humidity for both the Turbine Building control volumes and the outside environment are based on Drawings B-022-047 (DIN

6) and B-022-050 (DIN 7), respectively (see Table 1 below). All heat sinks are initialized at the same temperature as the Turbine Building control volumes.

8 Enercon is aware that the GE Thermal Kit identified in DIN 3 has been updated to contain the partial arc turbine modification. The latest Kit, 1LA0279, is contained in DI-237 Rev. 2. and gives an enthalpy of 1190.8 Btu/Lbm.

This GE value is only slightly greater than the value used in the GOTHIC analysis, thus it will have a minimal impact on the results of this calculation.

9 Liquid Volume Fraction 10 Steam Pressure Ratio 11 Due to the low flow rate, the flow momentum is not important to this analysis.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Turbine Building Thermal Characteristics Outdoor and initial Turbine Building temperature data (DIN 6, 7) is used to determine the Turbine Building thermal characteristics, thus providing a model which will give an adequate indication of temperature rise during the steam line leak.

Heat loads within each of the Turbine Building control volumes are approximated with artificial thermal conductors that contribute a specified heat flux to the Turbine Building. This feature of GOTHIC is used instead of heating components, because the conductors can be spanned over the entire subdivided volume, whereas heating components cannot be spanned. This method of approximating the heat load in the Turbine Building assumes that the heat load is distributed evenly. The correct heat load was determined through a trial-and-error method of simply setting all boundary conditions to those indicated in Table 1 below, and then modifying the heat flux of the conductors until the correct Turbine 2

Building temperature was achieved. Based on this methodology, a 10,000 ft steel conductor with the heat flux indicated in Table 1 was placed into each of the Turbine Building Control Volumes 3-7.

Based on this benchmark model, the boundary conditions will be adjusted and the MSL leak added to determine the thermocouple sub-volume temperature.

In addition to this, the heat load is introduced gradually to the Turbine Building, increasing from 0.7 of total at t = 0 seconds to unity at t = 1000 seconds (see forcing function #2 in Attachment E). This gradual introduction of the heat load decreases the time it takes for steady state to be achieved in the GOTHIC model.

Assumptions

1. Based on conversations with PNPP personnel, ventilation air remains at approximately 63°F for all outside air temperatures. Therefore, the ventilation air temperature is assumed to be 63°F.

2. For this analysis, the Steam Tunnel (Zone AB-7E) average temperature of 121°F (DIN 5) will be used for all cases. This is reasonable since the air flow between the Auxiliary Building steam tunnel and the Turbine Building is relatively small compared to the area ventilation flow rate.

3. Minor contributors to the total steel volume, such as stairs and handrails, are ignored. HVAC ducts are not included because they were determined to be insulated per drawings D-938-783 (DIN 49) and D-938-784 (DIN 50).

4. Leaks are assumed at three locations:

a) MSLB at 624 near TB14 (east wall) and TBE (Turbine Building centerline between north and south wall, sub-volume 7s15) b) MSLB at 592 near TB14 and TBI (southeast corner, sub-volume 7s11) c) MSLB at 592 near TB13 and TBI (southwest corner, sub-volume 7s12)

Adequate justification will be provided in the Flow Paths and Leak Locations section of this calculation to confirm that the three current leak locations represent limiting locations for the assumed steam leak in relation to the position of the temperature sensors.

5. An enthalpy of 1190.4 Btu/lbm (DIN 3) for the main steam line leak is based on thermodynamic 12 conditions at the current 100% power level . It is assumed constant for all MSL leak rates.

Turbine Building Temperature Response to Steam Leaks

6. A ground temperature of 53°F is assumed. The average between the hot (86°F) and cold (28°F) mean dry bulb temperatures (1% percentile) listed for Cleveland, Ohio in ASHRAE (DIN 1) is 57°F.

Thus, this is judged to be a conservative assumption.

7. All steam leaks (Flow Path 22) are set to point towards the west direction. Setting the steam leaks to point away from the thermocouples on the east wall maximizes conservatism.

8. All other assumptions are stated within the calculation.

Acceptance Criteria The temperature in the Turbine Building due to the 2.9468 lbm/sec steam leak must reach the particular analytical limit (145°F or 160°F) in less than 13 hours1.50463e-4 days 0.00361 hours 2.149471e-5 weeks 4.9465e-6 months 21 minutes 22 seconds.

The temperature in the Turbine Building due to the 10.99 lbm/sec steam leak must reach the particular analytical limit (145°F or 160°F) in less than 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months 34 minutes 53 seconds.

The temperature in the Turbine Building due to the 19.68 lbm/sec steam leak must reach the particular analytical limit (145°F or 160°F) in less than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

The temperature in the Turbine Building due to the 45.11 lbm/sec steam leak must reach the particular analytical limit (145°F or 160°F) in less than 52 minutes 21 seconds.

Basis: The total mass effluent from the steam line leak shall not exceed the total mass release from the main steam line break (141,687 lbm) within two hours. A leak rate that satisfies this criterion would ensure that the 10CFR100 site boundary dose limit is not exceeded.

Computation The thermal response over a 24-hour period at the location of the temperature sensors and at the steam leak is calculated by the GOTHIC computer program. For further information on how GOTHIC performs its analysis, refer to the GOTHIC Users Manual (DIN 4).

Also shown is the sub-volume temperature at the leak location (if different from the thermocouple sub-volume). The results over a 24-hour period for all 36 cases are displayed below. The following three summary items are listed below each graph.

A summary of the times required to reach 145°F and 160°F can be found in Tables 2 and 3, respectively, at the end of this section.

13 o o Data points created by the GOTHIC analysis typically did not occur exactly at 145 F or 160 F. Because of this, the data point was chosen that occurred at a time with a realized temperature closest to, but not less than, the target temperature (usually within a few tenths of a degree).

Turbine Building Temperature Response to Steam Leaks Conclusions The analysis results indicate that neither a 2.9468 Lbm/sec leak, nor a 10.99 Lbm/sec leak, will result in an elevated temperature of 145°F near the E31 temperature detectors for any analyzed condition. A 19.68 Lbm/sec leak will result in an elevated temperature of 145°F under the required 2 hrs, but not 160°F, for all analyzed conditions. Of the four leak rates, only a 45.11 Lbm/sec leak will result in an elevated temperature of 160°F near the E31 temperature detectors for the analyzed conditions. It does so in less time than the required limit of 52 minutes 21 seconds.

To determine the potential impact of these changes, test runs were performed for multiple cases. It was subsequently determined that the minor changes in steel conductor S.A. and thickness had no discernible impact on the final results.

It is important to note also that the steel heat sink totals are not more than a best estimate of all the exposed steel that exists in the Turbine Building zones of interest.
