L-002457 REVISION NO. 8 ATTACHMENT I, PAGE NO. I1 of 122 11.0 PURPOSE/OBJECTIVE The purpose of this attachment is to evaluate the UHS transient analyses with an allowable plant intake temperature of 104'F and an increased allowable plant intake temperature of 107 0 F for MUR PU and EPU power levels. Additionally, new weather data from January 1995 to September 2010 is considered in prediction of the UHS temperature response.

The initial lake temperature is adjusted such that the plant intake temperature remains below 104'F or 107'F during the accident scenario.12.0 METHODOLOGY AND ACCEPTANCE CRITERIA The S&L LAKET-PC computer program [Ref. 15.2] is utilized to determine the combined impact of decay heat, initial UHS temperature, and allowable sediment accumulation in the UHS. The maximum allowable UHS temperature is determined for average sediment accumulations of zero (0), six (6), twelve (12), and eighteen (18) inches.12.1 Methodology 12.1.1 Selection of Weather Data -The selection of the most limiting weather data is done in Attachment M. The worst weather day was determined to be 7/25/2001 ending at 6:00 AM and the worst weather month runs from 7/21/1995 4:00PM to 8/20/1995 3:00PM. The most limiting net evaporation month was determined to be from 6/18/1954 to 7/18/1954, which is unchanged from previous revisions of this calculation.

12.1.2 Lake Area and Volume -The initial lake elevation is 690-ft, which corresponds to the top water elevation of the UHS per the UFSAR. [Ref. 15.1]. However, UFSAR Section 9.2.6.3 [Ref. 15.1] states that 440,400 gallons of water from the UHS must be available for fire fighting following an accident (Design Input 14.3). Assuming that this inventory is removed from the UHS immediately following an accident (Assumption 13.2) leads to a decrease in the initial lake elevation of 690-ft and lake volume and area.440,400 gallons corresponds to 1.35 acre-ft of water and a 0.02-ft drop in lake elevation.

The initial lake level in the LAKET file is modified to incorporate these changes as shown in Table 12-1. The volume at an elevation of 689.98-ft is determined by subtracting the 1.35 acre-ft used in fire-fighting from the lake volume at 690-ft. The surface area is determined by interpolation using the information given in Table 7.1 of the main body of this calculation.

The effective volume and effective area are determined by multiplying the volume and surface area by the effective volume and effective area percentages determined in Attachment J (effective volume is 63.4% of total volume and effective area is 57.9% of total area).Table 12-1: Initial Lake Level e E o Effective Sediment Level Lake Elevation Area Volume Effective Area Volume (ft) (acre) (acre-ft) (acre) (acre" (acre-ft)18-in 689.98 81.32 340.0 47.08 215.59 12-in 689.98 82.12 380.5 47.55 241.24 6-in 689.98 .82.96 422.1 48.03 267.64 0-in 689.98 83.80 463.5 48.52 293.89 The remainder of the drawdown curve (from a lake elevation of 689-ft through 685-ft) remains the same as given in Table 7.1 of the main body of this calculation with respect to the total lake voluire and surface area. The effective volume and effective area are updated using the percentages determined in Attachment J.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT I, PAGE NO. 12 of 122 12.1.3 Plant Temperature Rise -The UHS heat load is increased due to an increase in power level. In addition, the core decay heat is changed as a result of EPU [Ref. 15.3] The new heat load on the UHS for EPU operation is determined in L-002453 [Ref. 15.4]. The plant temperature rise is dependent on the UHS heat load, and the calculation of the new plant temperature rise at MUR PU and EPU is documented in Attachment L.12.1.4 LAKET Case Runs -For the worst weather cases (cases ending with the letter a), the initial temperature for each case is iteratively set until the lake outlet temperature is equal to the maximum allowable lake outlet temperature (either 104'F or 107'F). The net evaporation cases use the same input file as the corresponding worst weather case, but are run with the most limiting net evaporation month weather file.A list of all cases run for this analysis is shown below: Table 12-2: List of LAKET Cases SPower Level Sediment Case Type Power Level Design Criteria S(MWt) Level la i Worst Weather 4067 (EPU) Pl-antInlet Temp=- 107"F 1c Worst Net Evaporation 4067 (EPU) 0" Initial Temp of Case la 2a Worst Weather 4067 (EPU) 1 6" Plant Inlet Temp = 107°F 2c Worst Net Evaporation 4067 (EPU) 6" Initial Temp of Case 2a 3a_12am Worst Weather 4067 (EPU) 18" Plant Inlet Temp = 1077F 3a_3am Worst Weather 4067(EPU)

The purpose of this is to determine at which time an accident would provide the most limiting results. For all other cases besides Case 3a, only the time determined to be the most limiting will be used.For EPU power level and a maximum allowable lake temperature of 107'F, the worst net evaporation cases are ran for all levels of sediment.

The worst case in terms of UHS drawdown is determined from the four different sediment levels, and the remainder of the worst evaporation cases are run at this sediment level only.12.2 Acceptance Criteria 12.2.1 Acceptance Criterion

  1. 1 -Peak Temperature

-The maximum plant inlet temperature from the UHS shall remain equal to or less than 104'F or 107°F.12.2.2 Acceptance Criterion

  1. 2 -UHS Drawdown -There are no specific acceptance criteria for maximumn UHS lake drawdown.

However, for the worst 30-day evaporation period, the maximum lake drawdown is determined for input to calculation L-00 1355 [Ref. 15.6].12.3 Limitations Same as main body of calculation.

12.4 Identification of Computer Programs Postprocessing of the LAKET-PC results is done using Microsoft Excel 2003 [Ref. 15.5], which is commercially available.

The validation of Excel is implicit in the detailed review of all spreadsheets used in this analysis.

All computer runs were performed using PC No. ZD6661 under the Windows XP operating system.LAKET-PC Version 2.2 [Ref. 15.2] was used to perform the lake transient analysis contained in this evaluation.

This was run on S&L PC No. ZD6661 on Windows XP operating system.I PROJECT NO. 11333-297 1

CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT I, PAGE NO. 14 of 122 13.0 ASSUMPTIONS 13.1 Fuel Pool Heat Load -It is assumed that the fuel pool emergency makeup pumps provide required makeup flow to the fuel pools. Including fuel pool heat loads is not realistic because it is improbable that the required operator actions to align the fuel pool emergency makeup pumps to the RHR system could be performed in the post-LOCA reactor building environment

[Ref. 15.3]. Therefore, the 600 gpm emergency fuel pool makeup flow rate (See Design Input 14.1) is added to the UHS seepage rate.13.2 UHS Inventory for Fire Fighting -It is assumed that all UHS inventory for fire fighting is used immediately following an accident.

This is conservative as it decreases the volume of water in the UHS.13.3 Effective Area and Volume at Different Sediment Levels -The effective area and volume percentages determined in Attachment J are determined for 18-in of sediment.

It is assumed that these percentages apply to the other sediment levels analyzed in this evaluation.

Since changes in sediment level change the depth of the lake evenly throughout the entire lake (see Section 6.2 of the main body of this calculation), the percentages of effective area and volume will negligibly change with sediment level.13.4 Other -All other assumptions are the same as the assumptions in the main body of calculation.

This will be added to the spent fuel pool makeup flow (See Assumption 13.1) to determine the total seepage rate of the UHS.14.3 UHS Inventory for Fire Fighting Following an Accident -Following an accident, 440,400 gallons of water from the UHS must be available for fire fighting [Ref. U5. 1, Section 9.2.6.3].14.4 Anemometer Height -For the worst net evaporation weather data, which is from the Peoria weather data spanning from 1948 to 1996, the anemometer height is 20-ft (as taken from input files for the worst net evaporation cases in previous revisions).

For the worst weather data, which is taken from the LaSalle Station weather data spanning from 1995 to 2010, the anemometer is at a height of 33-ft (See Attachment K).14.5 Other -All other design inputs are the same as the design inputs in the main body of calculation.

Changes from the determination of the plant temperature rise in previous revisions of this calculation included a change in the decay heat ratio as a result of EPU, the removal of fuel pool heat loads, and a one-hour time interval between calculations.

See Appendix L9.2 of Attachment L for the results of the plant temperature rise at MUR PU and Appendix L9.4 of Attachment L for the plant temperature rise at EPU.16.2 Seepage Rate The seepage rate is determined from a UHS seepage of 0.2 cfs (Design Input 14.2) and a constant flow of 600 gpm for spent fuel pool makeup (See Design Input 14.1). This gives a total seepage rate of 1.537 cfs, which a constant for all cases.16.3 Maximum Allowable Lake Temperature For this analysis, cases are run at MUR PU and EPU power levels. Each case is run with a limiting plant intake temperature of 104'F and 107'F, allowing for a comparison of the maximum allowable UHS temperature at the differing plant intake temperatures.

Limiting weather data is determined from two sets of weather data (See Attachment M).The time of day which the transient is assumed is critical when determining the maximum allowable initial temperature of the UHS. To account for the time of day at which the UHS transient may start, eight start times are used for the limiting sediment depth of 18-in. As seen in Table 17.1, the most limiting time is 6AM (as it results in the lowest allowable initial temperature).

Therefore, the remaining worst weather cases are run beginning at 6AM.In order to determine the limiting amount of sediment, the worst net evaporation case was run at four different sediment levels at EPU power level (Cases la, 2a, 3a, and 4a) for a maximum plant inlet temperature of 107°F. The case with no sediment (Case 1 a) was determined to be the most limiting (as it resulted in the highest drawdown).

Therefore, the remaining worst evaporation cases were run with a sediment level of 0-in.16.4 LAKET-PC Files The S&L LAKET-PC computer program [Ref. 15.2] was utilized to determine the combined impact of decay heat, initial UHS temperature, and allowable sediment accumulation in the UHS.

L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J2 of J40 J1.O PURPOSE The purpose of this attachment is to evaluate the water flow pattern in the man-made Ultimate Heat Sink (UHS) at LaSalle County Generating Station with the water depth at its minimum, that the water level is at elevation 690 ft [Ref. J5.1] and the UHS bottom is covered with approximately 1.5 ft of silt [Ref. J5.8]. The analysis is carried by means of computational fluid dynamics (CFD). The recirculation areas in the UHS are identified and the UHS volume actively involved in the main water flow is estimated along with and the associated surface area. The output of this evaluation is to provide effective lake volume and surface area for use in the S&L LAKET-PC computer program.J1.1 Background The UHS is designed to provide sufficient cooling water to permit the safe shutdown and cool down of the station for both normal and accident conditions.

In the unlikely event that the main dike is breached, there is a submerged pond within the cooling lake for the LaSalle County Station that is designed to hold water. This remaining water constitutes the ultimate heat sink for the station. It has a depth of approximately 5 feet and a top water elevation established at 690 feet [Ref. J5.1].Considering approximately 1.5 ft of silt at the bottom of the UHS, a CFD analysis is performed to predict the water main flow pattern and estimate the volume of water contained in the active zones of the UHS and the corresponding surface area. These inputs are used in main report to determine the combined impact of power uprate and allowable sediment accumulation in the UHS on the maximum plant inlet temperature and evaporative drawdown by use of the S&L LAKET-PC computer program.J2.0 METHODOLOGY AND ACCEPTANCE CRITERIA J2.1 Methodology J2. 1.1 Effective volume and effective surface area Figure J-3 shows a top view of the UHS computational domain. As shown, water enters the UHS in one of the UHS side branches and exits from the intake flume. Zones of recirculation are expected in the other branch of the UHS, which is a dead leg, and in proximity of the UHS inlet. LAKET-PC is a one-dimensional lake thermal prediction computer program [Ref. J5. 10]. The one-dimensional assumption coerces the water body into an idealized rectangular channel. In this idealization, water entering the channel displaces an equal amount of water out of the back end (see Figure J-1 ). At some time (t,)after the start of flow (to), the volume of displaced water is equal to Q.( t, -to), where is the Q is the flow rate of the water flowing into the channel. Indicating the total volume of the channel with Vchannel, all of the water is considered to have swept out of the channel at time t = to+Vchannel/Q.

However, if the lake being modeled has stagnant volumes, the water in those volumes would not be swept out of the exit as idealized in the LAKET-PC modeling.

For more accurately conforming the real lake to the idealized channel, these stagnant volumes and the corresponding surfaces must be removed from the active volume.PROJECT NO. 11333-297 CALCULATION NO.

Water displaced in the reference straight channel and in channel with recirculation zones.Figure J-2 shows both the idealized and actual amount of water displaced from a lake with recirculating (stagnant) volumes. If we could differentiate between water that was initially in the lake from new water entering the lake, we could use the concentration of initial water remaining in the lake at time t to find the fraction of water that was not swept out at time t. This is the fraction of the lake not actively participating in the channel flow.This volume and the corresponding surface area should be removed from the lake total dimensions to provide more accurate and conservative results.The amount of water initially in the channel at time to and still present in the channel, trapped in the recirculation zones, at time t = to + (Vchannel/Q) is calculated as follows (with to =0): Vtrapped in the reciruclation zones (t) = Jc V initial water in the channel (t)dV (J2.

The effective surface area is calculated in manner similar to the effective volume. At the surface of the channel, the amount of water initially in the channel at time to and still present in the channel, trapped in the recirculation zones, at time t = (Vchannel/Q) is calculated as follows: S trapped in the reciruclation zones (t) = JC S initial water in the channel (t)dS (J2.1-3)Schannel where Schannel is the total surface of the channel and CSinitial water in the channel(t) is the surface distribution of water initially in the channel at time to and still present in the channel at time t.

L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J5 of J40 J2.1.2 Calculation strategy As indicated in Section J2.1.1, the volume and surface averaged concentrations of the water initially in the UHS at to = 0 sec still present in the UHS at time t = VUHs/Q are necessary in order to calculate the effective UHS volume and surface.The analysis of the water flow in the UHS is carried out through the use of the commercially available CFD code STAR-CCM+

[Ref. J5.2]. The calculation is performed in two steps: I. The first step is employed to find the steady state flow distribution in the UHS. This solution is used as initial condition for the transient multi-component fluid mixture in the second step.2. During this second step, newly introduced water in the UHS is specified to be a different liquid but with the same properties of the water already present in the UHS.The flow pattern and mixing of these liquids are calculated and tracked over time from time to = 0 sec to t = VuHs/Q. At the end of the transient analysis, the surface average concentration of the amount of water initially in the UHS and still present in the UHS at time t = VUHs/Q are calculated to find the effective volume and surface.J2.1.3 Geometrical domain The CFD analysis is carried out in three-dimensions.

For the computations, the water domain is considered from the outlet of the inlet chute into the UHS to the exit of the intake flume. Figure J-3 shows a top view of the computational domain while Figures J-4 and J-5 show the inlet and outlet boundaries, respectively.

Figure J-6 shows the bottom view of the UHS. Design Input J4.1 reports the dimensional information used to generate the model. Assumption J3.1 is used to evaluate the UHS thickness.

The main dimensions are indicated in Figures J-1 to J-3. Figures J-4 to J-7 also show, in quotations, names associated to each of the boundaries in the numerical model. Note that this evaluation reports the fraction of active volume and surface area. Therefore, slight variations in the lake dimensions will not significantly affect the final results.J2.1.4 Mesh The computational domain is discretized by using polyhedral cells with a base size of 12 ft, and six thin layers through the thickness of the UHS. Where necessary, the cell size is reduced down to 6 ft and, in proximity of the inlet boundary, down to 1.5 ft. Figures J-5 to J-8 show the mesh employed for the computations, which consists of 1,761,870 nodes for a total of 748,386 cells. Appendix J8.1 provides the STAR-CCM+

report of the mesh quality.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J6 of J40 CALCULATION NO.

L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J9 of J40 J2.1.5 Numerical model As indicated in Section J2.1.2, the calculation is carried out in two steps.Step One: Steady State Single-Fluid Analysis The numerical analysis is carried out using the segregated SST (Menter) k-wO model with the all y+ wall treatment.

The shear stress transport (SST) formulation is a blend of a k-(0 formulation, which is used near walls, and a k-e formulation, which is used in regions far from walls. The use of a k-co formulation in the inner parts of the boundary layer makes the model directly usable all the way down to the wall through the viscous sub-layer without additional modifications.

Hence, the SST k-w model can be used as a low Reynolds turbulence model without any extra damping functions.

The SST formulation also switches to a k-c behavior in the free-stream and thereby avoids the common k-o0 problem of being too sensitive to the inlet free-stream turbulence properties.

This model is fairly robust, it demonstrated superior performance for wall bounded problems and low Reynolds number flows, it showed potential for predicting transition regions and it also is often found to do a better job at capturing recirculation regions than other models [Ref.J5.2].Therefore, the SST (Menter) k-o model with the all y+ wall treatment is particularly suited for the geometry analyzed in this calculation which presents a confined flow with very extensive surface associated to an extremely small thickness, and a uniform mesh through the thickness of the domain as generated by the thin mesher generator.

A constant-density single-fluid is specified as working liquid with the properties of water at 100°F (see Assumption J3.2) with a density of approximately 62 lb/ft 3 and a dynamic viscosity of 6.727"10-9 atm-s [Ref. J5.7].The following boundary conditions are applied:* "FreeSurface" -This boundary represents the free surface of the lake. As a simplification, this boundary is considered to be rigid in order to reduce the computational time. This simplification does not significantly impact the results of the calculation since the water velocity is small and very small or no waves are expected to form (tranquil flow). Furthermore, this boundary is specified to be a symmetry plane in order to guarantee a zero shear stress (free surface flow)." "Inlet" -This boundary represents the inlet to the UHS. It is specified to be a mass flow inlet boundary with an inlet flow rate of 86 ft 3/sec, which is approximately equal to 5333.7 lb/sec [Ref. J5.8].* "Outlet" -This boundary represents the outlet to the UHS. It is specified to be a simple pressure outlet boundary.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT J, PAGE A 0 of J40* "Soil" -This boundary represents the bottom and sloped sides of the UHS. It is specified to be a rough no-slip wall boundary with a roughness of 5.0 in (see Assumption J3.3).The system is initialized with constant zero velocity and pressure and let to evolve to final steady state solution.Step Two: Transient Two-Fluid Analysis The results of Step One are used as initial condition to the calculation performed in this second phase. The following changes are made to the model: 1. Transient solver -The solver is specified to be implicit unsteady with maxinmm number of inner iteration per time step equal to 20. The time step is adjusted through the computation for an initial minimum value of 0.1 sec to a final maximum value of 100 sec. The transition from one time step to the other is nonrmally performed after ensuring that the residuals are always small and the solution is converged at each time step.2. Two-fluid specification

-The solver is changed to account for a two fluid mixture.Both fluids have the properties of water at 100°F and the are labeled "WaterLake" for the water initially present in the UHS at the beginning of the transient analysis (from Step One) and "WaterCirculating" for the water injected from the "Inlet" boundary.For the two-fluid mixture, the code can compute the mixture properties based on the local concentration of the two base fluids and their molecular weight. Since there is no difference between the "WaterLake" and "WaterCirculating", the properties of the mixture are specified to be constant and equal to that of water at I 00'F.In order to compute the diffusion of one liquid into the other, the Schmidt number and the turbulent Schmidt number need to be specified for the mixture. The Schmidt number is a dimensionless parameter defined as the ratio of momentum diffusivity and mass diffusivity as [Ref. J5.2]: Schmidt- P (J2.1-5)P Dim where Vt is the dynamic viscosity, p is the density and Dim is the molecular diffusivity of component-i into the mixture. The Schmidt number used in this analysis is equal to 219.8 (see Appendix J8.2). The turbulent Schmidt number is taken as the default value in STAR-CCM+

which is equal to 0.9. This implies that the turbulent mass diffusivity is proportional to the turbulent viscosity, which is an unknown a-priori variable and it is locally computed by the code. Note that the computed solution is fairly insensitive to the choice of the Schmidt number and the turbulent Schmidt number within the range of realistic values. The molecular weight for both fluids, which is another input required to compute the mass diffusivity, is specified to be 18.0153 lb/lbmol [Ref. J5.9].PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J 11 of J40 3. Boundary conditions

-The boundary conditions are kept the same as for the steady-state analysis.

However, the fluid entering the "Inlet" surface is specified to the 100%"WaterCirculating" and, in case of backflow at the "Outlet" surface, the re-entering fluid is specified to the 100% "WaterLake".

This last condition is specified only to complete the STAR-CCM+

input file for this analysis but it is not used during the computation.

4. Initial conditions

-The results of steady state analysis are used as initial conditions for the transient calculation.

The liquid present in the UHS at the beginning of the transient simulation (t = 0 sec) is specified to be 100% "WaterLake".

5. Simulation time -The calculation is perforned from time tstart = 0 sec to time tend =VUHs/Q. The total volume of the UHS is manually requested and printed out by STAR-CCM+

after the generation of the computational domain and it is equal to VUHS = 1.454446"107 ft 3.The flow entering the UHS is equal to 86 ft 3/sec [Design Input J4.2]. Therefore, tend = VUHs/Q = (1.454446' 10' ft 3)/(86 ft 3/sec) = 169,122 sec 47 hrs.After the completion of the transient simulation, the volume and surface average concentrations of "WaterLake" are computed and the results are used to manually calculate the UHS effective volume and surface as percentages respectively of the total UHS volume and surface by applying equations J2.1-2 and J2.1-4 as follows: Veffective

This information is gathered to support thermal analysis of the UHS performed in the main report.For the CFD analysis, the computational mesh must be of acceptable quality, as verified by Appendix J8. 1. Furthermore, the calculated results must be converged as verified by the plot of the residuals in Appendix J8.3 (page J31).PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J 13 of J40 J3.0 ASSUMPTIONS J3.1 Silt thickness

-The depth of the silt layer at the bottom of the UHS is assumed to be 1.5 ft (see Design input 5.3). The use of 1.5 ft silt thickness (maximum allowed value) causes the calculation of a reduced UHS effective volume.J3.2 Water temperature

-The water in the UHS is assumed to be at a constant temperature of 100'F. This input is used to estimate the density, viscosity and self-diffusivity of water in the UHS. This input does not significantly impact the results of this calculation.

J3.3 Soil roughness

-The roughness of the bottom of the UHS (including the silt layer) is assumed to be 5 in. Since this calculation determines the UHS inactive volumes rather than pressure losses, based on the calculated UHS low water velocities, this input does not significantly impact the results of this calculation.

J4.0 DESIGN INPUTS J4.l UHS dimensions

-The UHS dimensions are obtained from References J5.3 to J5.6 as follows: i. The nominal elevation of the UHS cooling pond bottom is approximately 685 ft[Ref. J5.5].ii. The elevation of the bottom of the intake flume is approximately 678.5 ft [Ref.J5.5].iii. The bottom of the UHS between the cooling pond and intake flume is approximately flat and its depth varies from 678.5 ft to 685 ft in a linear manner[Refs. J5.3 to J5.6].iv. The slope of the UHS side is approximately 1:4 all around its perimeter

[Refs.J5.3 to J5.6].v. The width of the water inlet chute is 8 ft [Ref. J5.4].vi. The width of the intake flume bottom is approximately 40 ft [Ref. J5.6].vii. The dimensions of the UHS that are not listed above are scaled from Reference J5.3.viii. The elevation of the UHS free surface is 690 ft [Ref. J5.1].J4.2 UHS flow -The mass flow rate through the UHS is equal to 86 ft 3/s [Ref. J5.8].J4.3 UHS sediment level -The sediment level in the intake flume and cooling pond must remain less than or equal to 1.5 ft [Ref. J5.8]. The use of maximum silting reduces the PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J14 of J40 UHS volume, and therefore the residence time. This reduces the effectiveness of the UHS and it is thus conservative.

J4.4 Properties of water -Water at 1007F has the following properties:

density z 62 lb/ft 3;dynamic viscosity z 6.727.10-9 atm-s [Ref. J5.7].J

-Time variation of the"WaterLake" volume average concentration in the UHS.Figure J-14 shows the trend over time of the "WaterLake" volume average concentration.

As seen, the concentration decreases linearly at the beginning since the incoming water displaces the water in the UHS. After about 20 hrs, some the incoming water is already exiting the UHS and thus "WaterLake" volume average concentration change is no longer linear: some of the incoming water is being trapped in the areas of recirculation and it cannot efficiently displace the "WaterLake" out of the UHS.After 47 hrs, the volume average concentration is computed to be 36.59 %. Therefore, the UHS effective volume percentage as compute by Equation J2.1.6 is equal to (see Appendix J8.3): Veffective

= 1 -0.3659 = 63.4%VUHS (J2.1-8)PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT J, PAGE J18 of J40 After 47 hrs, the surface average concentration is computed to be 42.09 %. Therefore, the UHS effective surface percentage as compute by Equation J2.1.7 is equal to (see Appendix J8.3: Seffective

7.0 CONCLUSION

The UHS effective volume as percentage of the UHS total volume is 63.4 %.The UHS effective surface as percentage of the UHS total free surface is 57.9 %.J8.0 APPENDICES J8.1 STAR-CCM+

[Sec. 6, Ref. 1].Request "a": The dimensions of the inlet channel are shown in Figure J-4 in the main body of the calculation.

As seen, the channel cross-section is modeled as a rectangular area 8 feet wide and 3.5 feet high, which is an accurate representation of the actual inlet channel. The inlet velocity of the water is equal to approximately 3.07 ft/s, which corresponds to 86 ft 3/s (see Section J.2.1.5 in the main body of the calculation).

This is an accurate modeling of the inlet water velocity based on the dimensions of the discharge channel. The roughness of the bottom of the UHS (including the silt layer) is assumed to be 5 in. As indicated in Assumption J3.3 in the main body of the calculation, this value does not significantly affect the result of the analysis which is the overall water flow pattern and speed within the UHS.Figures J.8.6-1 to J.8.6-3 show the nodalization used at the inlet region of the UHS model (see also Section J2.1.4 in the main body of the calculation).

Recirculation loops at the entry region Project No. 11333-297 Calculation No. L-002457 Appendix J8.6 Revision No.8 Attachment J Page J40 of J40 Request "d": The use of constant density fluid and thermal stratification effects in the UHS are addressed in Attachment N, Section N6.4.The purpose of the CFD analysis is to evaluate the water flow pattern in the man-made Ultimate Heat Sink (UHS) at LaSalle County Generating and to provide effective lake volume and surface area for use in the S&L LAKET-PC computer program. Recirculation regions are present in the UHS due to its shape, which causes the water to flow in a non-straight path. Since water can be practically considered an incompressible fluid, the average velocity distribution within the UHS is governed by the conservation of mass. Changes in average water temperatures within the range of expected values (-100'F to 120'F)produce small changes in water properties and thus may marginally affect the local water velocity distribution.

However, these changes would not cause a significant change in the UHS overall water flow pattern and thus to the size of the recirculation regions. Therefore, the results of the CFD calculation are insignificantly affected by a change in water temperature.

L-002457 RBASION No. 8 ATTACHMENT 1-ý PAGE K2 of K6 Preparation of Hourly Meteorological Data Used for Cooling Lake Analysis 1 Purpose This attachment describes update of a meteorological data input file provided to support a validation study of the cooling lake at the LaSalle County Nuclear Generating Station, near Marseilles, IL. The file was expanded to include older data collected from January 1, 1995 -December 31, 2004. The updated file now includes the period of record from January 1, 1995 -September 30, 2010.2 Parameters included in the Meteorological Data File The meteorological data file was compatible with the Laket program (Reference 1), which S&L uses to evaluate the thermal performance of cooling lakes. The parameter content and digital format of Laket meteorological files are listed in Table 1.3 Meteorological Data Selection Wind and temperature data were taken from an on-site meteorological tower at the generating station. The on-site tower measured the dry-bulb temperature and wind speed/direction at three levels: 33 ft., 200 ft. and 375 ft above ground level. Wind speed/direction and dry-bulb temperature from the lowest level (33 ft, or 10.1 meter) level were extracted for use in Laket.The on-site meteorological tower contractor supplied the on-site tower data in the form of digital text file.The on-site meteorological tower did not collect hourly humidity, precipitation type, cloud height and cloud cover, which are required inputs for Laket. These parameters were taken from a National Weather Service observing station at the Peoria, IL airport (station identifier KPIA).That weather station is located approximately 70 miles southwest of the generating station.4 Raw Meteorological Data Observed ("raw") meteorological data from KPIA were used to develop the meteorological data input file for Laket. Raw data were purchased from the National Climatic Data Center (NCDC)in Asheville, NC. Two separate digital files were purchased.

These two files are briefly described below.(1) Surface Weather Observations Raw surface weather observations (Reference

2) from KPIA covered the period of record from January 1, 1995 through December 31, 2004. NCDC subjects meteorological data to rigorous quality control checks before archiving it. Nevertheless, meteorological databases still typically include gaps and data values outside of valid ranges. The PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT K, PAGE K3 of K6 archived data included most of the weather parameters required by Laket (Table 1), with the following exceptions:

freezing precipitation code, solar radiation, atmospheric radiation, and partial pressure of water vapor. S&L estimated those parameters using standard methods. To check the thermodynamic consistency of the input data, S&L estimated hourly wet bulb temperature, dew point temperature and humidity to ensure consistency between those parameters and the (on-site) dry-bulb temperature.

In instances when the dew point temperature at KPIA exceeded the dry-bulb temperature at the on-site meteorological tower, the dew point temperature at KPIA was set equal to the dry-bulb temperature observed at the on-site tower. This ensured thermodynamic consistency between the relative humidity and the dry-bulb, wet-bulb temperature and dew point temperatures.

(2) Precipitation Data Raw hourly digital precipitation data (Reference

3) from KPIA were available for the period of record from January 1, 1995 through December 31, 2004.5 Creating Input Meteorological Data for Laket S&L uses a series of modular computer programs collectively called the Surface Data Generator ("Surgen")

and judgements and adjustments by a qualified, experienced, professional meteorologist to create digital meteorological data files for input into Laket. Key requirements of Laket include a specific set of weather parameters and specific digital format (Table 1), and a complete meteorological database with no bad (out of range), or missing, parameters.

Surgen modules are executed independently and perform the following functions:

(1) Interpret the unique digital formats of raw surface weather observations and precipitation data and extract required meteorological parameters.

(2) Convert numeric units of extracted parameters to those required by the Laket program.(3) Scan hourly surface weather observations, and identify periods when values for selected parameters are either missing or invalid (outside of acceptable ranges). Those periods are identified by starting and ending date, and by the length of each gap (in hours).(4) Scan hourly surface weather observations, identify periods within the digital file when whole days or specific hours are missing; insert new, or blank records into the file to fill time gaps.(5) Estimate values for the following weather parameters:

an indicator whether precipitation is liquid or frozen, solar radiation reaching the lake surface, atmospheric radiation reaching the lake surface, partial pressure of water vapor in the atmosphere, wet bulb temperature and dew point temperature.

PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION No. 8 ATTACHMENT K, PAGE K4 of K6 (6) Perform simple linear interpolation of weather parameter values through gaps, and insert the new interpolated values into the database.(7) Allow insertion of manually selected substitution values into gaps in the database that are judged not to be suitable for simple linear interpolation.

(8) Translate processed and adjusted databases into the format required by the Laket program.Since the project required combining wind and temperature data from an on-site meteorological tower with data collected at another site (Peoria, IL), S&L developed a project-specific FORTRAN program which merged the on-site wind speed/direction and dry-bulb temperature data with other data from KPIA. The program produced a single input file that was subsequently processed with Surgen, as described above.6 Review and Adjustment of Meteorological Data Surgen identified short periods of missing, or bad (out of range), raw meteorological data and used linear interpolation to fill short gaps that were generally 1-2 hours long. However, there were three periods identified which had data gaps too long for linear interpolation.

Data were manually substituted from Peoria in these periods. These periods are listed below: Wind direction and speed from Peoria, IL was used for the following periods: (1) 10/30/97 21:00 local standard time (LST) through 11/03/97 14:00 LST (2) 08/23/02 05:00 LST through 09/04/02 11:00 LST The anemometer height at Peoria during both of these time periods was 32.8 ft (10 meters) (Reference 4).Dry bulb temperature from Peoria, IL used for the following period: (3) 06/15/98 08:00 LST through 06/16/98 11:00 LST 7 Laket Meteorological Input File Surgen produced a single Laket meteorological input file which was appended to the original meteorological data file produced in 2011. The specifications of the original and combined (updated) file are listed below PROJECT NO. 11333-297 CALCULATION NO.

(10.1 meter) level of the on-site meteorological tower at the generating station.9 References

L5.1]. This temperature rise is to be used in the LAKET-PC [Ref. L5.3] model of the LaSalle County Station UHS.PROJECT NO. 11333-297 Non-proprietary version CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT L, PAGE L4 of L58 L2.0 METHODOLOGY The plant temperature rise is used in LAKET-PC [Ref. L5.3] to compute the rise in water temperature caused by the heat rejected to the UHS during the postulated accident.There are two types of heat loads that are considered when determining the CSCS temperature rise across the plant: 1) the total generated heat load and 2) the sensible heat load. The total generated heat load can be further divided into decay heat load, pump heat load and cooler heat load. Heat load from the spent fuel pool is not considered since it is improbable that required operator actions could be performed in the post-Loss Of Coolant Accident (LOCA) reactor building environment (Assumption L3.4). The total heat load, consisting of the generated heat load and the sensible heat load, is the heat rejection to the UHS and is used to determine the plant temperature rise.The total generated heat load (Design Input L4.1) is computed for various time steps between zero seconds and IE+9 seconds in Calculation L-002453 [Ref. L5.1]. Linear interpolation of the results from L-002453 is used to detennine the integrated total generated heat load at each time step.The total sensible heat load is determined to be [R ]] (Design Input L4.2). It is assumed that all sensible heat is dissipated to the UHS at a constant rate within six hours (See Assumption L3.2).Once the heat rejection to the UHS is determined by adding the total generated head load and the sensible heat load, the temperature rise through the plant is determrined by the following equation: AT= Q (Eq. L3-1)where: AT = plant temperature rise ['F]Q = heat rejection rate to the UHS [BTU/hr]Cp = specific heat capacity of water [BTU/(lbm-°F)]

m = mass flow rate [lbm/hr]The mass flow rate is determined by converting the CSCS volumetric flow rate of 86 ft 3/s (Assumption L3.3) to a mass flow rate at a density of 62.0 lb,n/ft 3 (Assumption L3.1).L2.1 Computer Programs and Software The analysis performed herein utilizes Microsoft Excel 2003 [Ref. L5.4], which is commercially available.

The validation of Excel is implicit in the detailed review of all PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT L, PAGE L5 of L58 spreadsheets used in this analysis.

All computer runs were performed using PC No.ZD6661 under the Windows XP operating system. Excel Add-in function STMFUNC is used to calculate the thermal properties of water and steam at varying operating conditions

[Ref. L5.5]. The Excel Add-in function STMFUNC has been validated and approved for use in accordance with the S&L Quality Assurance (QA) program.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT L, PAGE L6 of L58 L3.0 ASSUMPTIONS L3.1 Water Properties

-The properties of water are evaluated at a temperature of 100°F and atmospheric pressure.

The density and specific heat capacity of water at 100°F and 1 atm are 62.0 lbm/ft 3 and 0.998 BTU/lbm-°F, respectively

[Ref. L5.5].L3.2 Sensible Heat Load from Reactor Coolant System -It is conservatively assumed that all of the sensible heat from the reactor and the primary system is dissipated to the UHS within six hours. One-sixth of the heat is assumed to be rejected per 1-hour time step until the full sensible heat load is rejected by the sixth hour. This is based on the assumption that the temperature within the reactor will be at 100°F within six hours.L3.3 CSCS Volumetric Flow -The total plant flow during the UHS analysis is assumed to be 38,600 gpm (86.0 ft 3/s). The total flow is based upon the cumulative flow contribution from thirteen CSCS pumps operating at design flow conditions (eight Residual Heat Removal (RHR)-Service Water pumps, 4,000 gpm each; three Diesel Generator (DG)pumps, two at 1300 gpm and one at 2,000 gpm; and two High Pressure Core Spray DG pumps, 1000 gpm each) (See Attachment D).L3.4 Spent Fuel Pool Heat Load -Heat load from the spent fuel pool is not considered because it is improbable that required operator action (RHR alignment) could be performed in the post-LOCA reactor building environment.

Instead, the fuel pool emergency makeup pumps are modeled as providing required makeup flow to the fuel pools at 600 gpm [Ref.L5.2].PROJECT NO. 11333-297 Non-proprietary version CALCULATION NO.

L5.1]. These results are presented in Appendix L9.1 for MUR PU and Appendix L9.3 for EPU and are used to determine the temperature rise through the plant.L6.2 Plant Temperature Rise In order to facilitate the creation of a LAKET-PC [Ref. L5.3] input file, the plant temperature rise results are determined in one hour increments.

This requires linear interpolation of the integrated total generated heat load found in L-002453 [Ref. L5.1] to determine the integrated total generated heat load at hourly intervals.

Adding the integrated total generated heat load and the sensible heat load gives the total heat load, which is the heat rejected to the UHS used to determine the plant temperature rise. The plant temperature rise is calculated in Excel using Eq. L3-1. The results of this calculation are shown in Appendix L9.2 for MUR PU and Appendix L9.4 for EPU.PROJECT NO. 11333-297 CALCULATION NO.

L-002457 REVISION NO. 8 ATTACHMENT M, PAGE M3 of M17 M1.0 PURPOSE / OBJECTIVE The purpose of this attachment is to determine the worst 24-hour and 30-day weather period and the worst 30-day period of net evaporation for LaSalle County Station. The new weather data is compared to the weather data used in the existing analysis to determine if the new weather data set is more limiting.

If the existing weather data is no longer bounding, new LAKET weather files are compiled.

This will be used as input in determining the maximum plant inlet temperature and evaporative drawdown of the LaSalle County Station Ultimate Heat Sink, which determines the design basis Ultimate Heat Sink (UHS) performance for 30 days following an accident.

Weather data has been provided from January 1, 1995 through September 30, 2010.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT M, PAGE M4 of M1 7 M2.0 METHODOLOGY A LAKET-compatible meteorological data file, 'PIALSL9510.txt', was created consisting of meteorological data for LaSalle County Station and Peoria, IL from January 1, 1995 through September 30, 2010. See Design Input M4.1 for additional information on this file. Wind speed, wind direction, and dry-bulb temperature data were taken from an on-site meteorological tower at LaSalle County Station. Humidity, precipitation type, cloud height, and cloud cover data were not available from the on-site meteorological tower, and were taken from a National Weather Service observing station at the Peoria, IL airport (approximately 70 miles southwest of LaSalle County Station).

This weather data file is input to LAKET [Ref. M5.2], and the worst weather and worst net evaporation time periods are found from the range of dates included in this file.Based on options selected in the input file, the LAKET run returns a plot file that includes the total evaporation, precipitation, natural lake temperature, lake inlet temperature (same as the plant outlet temperature), and the UHS outlet temperature (same as the plant inlet temperature).

Since LAKET returns results in three hour increments, a rolling average over 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is created using Microsoft Excel [Ref. M5.1] by averaging the UHS outlet temperature of the selected time step along with the previous seven time steps. The worst weather day is chosen as the day with the highest UHS outlet temperature 24-hour rolling temperature average. The worst 30 days of weather is detennined using a similar methodology, in which a 30-day rolling average of the UHS outlet temperature is calculated and the maximum is chosen as the representative worst weather month.M2.1 Worst 24-Hour and 30-Day Weather A specific UHS model was created in LAKET (based on Case 3a from Attachment H)with a transit time that corresponds to the three hour time step period. Case 3a is used since it uses a worst 1-day plus worst 30-day weather file and represents the worst case scenario of 18-in sedimentation.

The following changes were made to Case 3a for determining the worst weather conditions:

  • The date range is changed to match the date range of weather file 'PIALSL95 I 0.txt.'* The lake initial temperature is set at 100°F. (Assumption M3.1)* The model is set as open cycle, so the UHS is at the same temperature at the beginning of each 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> interval.* Anemometer height is set at 33-ft in accordance with the instrument setup at LaSalle County Station (Design Input M4.2).* Lake elevation is fixed at 690-ft (Assumption M3.2).* The circulating plant flow is set at 873.0 ft 3/s for a circulation time of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />.* The plant discharge water temperature (TPRISE variable in LAKET) is set at 100°F (Assumption M3.3). For an open cycle model, this value is the lake inlet temperature.

PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT M, PAGE M5 of M17* Effective area and effective volume are set to 57.9% of total area and 63.4% of total volume, respectively, due to the results of Attachment J -UHS Flow Path Analysis.The UHS outlet temperature for each 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> period corresponds to the environmental effects on the UHS during these three hours. From these results, it can be implied that higher UHS outlet temperatures represent worse (hotter) weather conditions.

M2.2 Worst 30-Days of Net Evaporation For determining the worst 30-days of net evaporation, a UHS model is created in LAKET (based on Case 3c in Attachment H). Case 3c is used since it uses a worst 30-day net evaporation weather file and represents the worst case scenario of 18-in sedimentation.

The following changes were made to Case 3c for determining the worst net evaporation conditions:

  • The date range is changed to match the date range of weather file 'PIALSL950O.txt.'
  • Anemometer height is set at 33-ft in accordance with the instrument setup at LaSalle County Station (Design Input M4.2).* Lake elevation is fixed at 690-ft (Assumption M3.2).* Initial temperature is set at 407F as a representative winter UHS temperature (Assumption M3. 1).* The temperature rise through the plant (TPRISE variable in LAKET) is set at the approximate average temperature rise at EPU of -9°F (Assumption M3.3).* Effective area and effective volume are set to 47.10 acres and 216.45. acre-ft, respectively, due to the results of Attachment J -UHS Flow Path Analysis and the Case 3c model area and volume.The net evaporation is calculated by subtracting precipitation from the total evaporation.

The worst 30 days of net evaporation is determined using rolling averages, similar to the methodology used in determining the worst weather.M2.3 Weather File Creation for Comparison to Existing Analysis Following determination of the worst weather days and the worst net evaporation days, weather files for input to LAKET are created. For the worst weather input file, conditions from the worst weather day are used as the first day in the new weather file.Following the first day, the conditions from the worst 30-day period are added to create a 31-day worst weather "month." Precipitation is conservatively set to zero for all time steps comprising the worst weather month (Assumption M3.4). To determine if this new worst weather month is more limiting than the existing worst weather month used in Attachment H, the input file from Case 3a is ran using the new worst weather month. If the new weather month does not result in a higher maximum UHS outlet temperature, the existing worst weather month will be retained as it is more severe.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT M, PAGE M6 of M17 For the worst net evaporation weather file, the conditions from the worst 30-day period are compiled to create a 30-day worst net evaporation "month." Similar to the worst weather month, precipitation is set to zero for all time steps (Assumption M3.4). To detennine if this new worst net evaporation month is more limiting than the existing worst net evaporation month from Attachment H, the input file from Case 3c is ran using the new worst net evaporation month. If the new weather file does not result in more lake drawdown, the existing worst net evaporation month will be retained as it is more severe.M2.4 Weather File Creation for UHS Analysis If the existing weather file is not bounding, new weather files are created based on the new most limiting day and month determined by this analysis.

These weather files use the weather information provided in 'PIALSL95IO.txt' with the following changes: " The station code is set to zero. This input has no impact on the results of this analysis.* The start date and time is set at 7/1/1900 at 12AM. This input has no effect on the results of this analysis." Precipitation is set to zero for all time steps (Assumption M3.4).In order to determine the effect of the time of day of the worst weather day on the UHS, eight different worst weather files will be created. The first file will start at 12 AM of the worst weather day followed by subsequent files at 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> intervals (e.g. the second weather file starts at 3 AM of the worst weather day). After 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the worst weather day, the worst 30 days subsequently added to the file. The start of the worst 30 days is selected to maintain a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> interval between time steps. For example, if the worst 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> day ends at 11PM, the next time step will be at 12AM of the beginning of the worst 30 days.For the worst net evaporation, only one weather file will be created, corresponding to the dates and times determined to be the most limiting.M2.5 Computer Programs and Software LAKET-PC Version 2.2 [Ref. M5.2] was used to perform the lake transient analysis contained in this evaluation.

This was run on S&L PC No. ZD6661 on Windows XP operating system.Postprocessing of the LAKET-PC results is done using Microsoft Excel 2003 [Ref.M5.1], which is commercially available.

The validation of Excel is implicit in the detailed review of all spreadsheets used in this analysis.

All computer runs were perfon-ned using PC No. ZD6661 under the Windows XP operating system.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT M, PAGE M7 of M17 M3.0 ASSUMPTIONS M3.1 Initial Lake Temperature

-For the worst weather evaluation, the initial lake temperature is set at 100°F. This is an arbitrary reference value for determrining the relative weather severity and does not influence the results of this analysis.For the worst net evaporation month, the initial lake temperature is assumed to be 40'F.This is used as a representative value for the lake temperature during the winter since the weather data file begins on January 1. This does not influence the results of this analysis as the worst net evaporation month occurs during the summer.M3.2 Fixed Lake Elevation

-The lake elevation when determining the worst weather month and worst net evaporation month is fixed at 690-ft. A constant lake elevation removes the effects of lake level in determining the weather effects on the UHS temperature and evaporation.

M3.3 Station Thermal Boundary Condition

-The plant discharge water temperature when determining the worst weather day and month is assumed to be 100°F. Since the lake is modeled as open cycle, the lake starts at this temperature at the start of each 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> time interval.

A constant initial temperature allows for isolation of the meteorological effects on the lake.When determining the worst net evaporation month, the temperature rise through the plant is assumed to be constant at approximately 9°F, which is the average temperature rise for EPU over the calculated 30 day period (Calculated from Appendix L9.3 of Attachment L -Plant Temperature Rise). A constant temperature rise through the plant removes the effects of the plant heat load in determining the evaporation.

M3.4 Precipitation

-When creating the worst weather "month" and worst net evaporation"month," precipitation is set to zero for all time steps. This is conservative when determining the limiting initial UHS temperature.

These results are then compared to the existing weather files used in the Attachment H of this calculation.

M6.1 Worst Weather Conditions LAKET input file 'Worst Weather.dat' was compiled to detennine the worst weather day and 30-day period from 1/1/1995 to 9/30/2010.

The worst weather file is created by first inputting the worst 24-hr day (7/25/2001 ending at 6:00 AM) and then inputting the worst period of 30 days (7/21/1995 4:00PM to 8/20/1995 3:00PM) to create a 3 1-day weather file.To compare the new weather file with the existing weather file, Case 3a from L-002457 was run using the new weather file. This was done by creating a LAKET input file,"WorstWeatherComparison.dat,'

with the same conditions as Case 3a, but an adjusted anemometer height to reflect the setup at LaSalle County Station. As seen in the output file, 'WorstWeather Comparison.out,'

the maximum UHS outlet temperature using the new worst weather file is 105.967F.

From Attachment H, the results from Case 3a using the existing weather file is a maximum UHS outlet temperature of 104.00'F.

The new weather file results in a greater UHS outlet temperature, so it will replace the existing worst weather file in the UHS analysis.PROJECT NO. 11333-297 CALCULATION NO.

is created by inputting the weather conditions from the worst net evaporation period of 30 days (6/13/2002 10:00 PM to 7/13/2002 9:00 PM). In order to compare this with the worst 30 day net evaporation period from Attachment H, Case 3c from Attachment H was run using the new weather file.

with the same conditions as Case 3c, but an adjusted anemometer height to reflect the setup at LaSalle County Station.As seen in the output file, 'NetEvapComparison.out,'

the minimum lake elevation using the new worst net evaporation weather file is 688.63-ft.

From Attachment H, the results from Case 3c using the existing weather file is a minimum lake elevation of 688.52-ft.

Since the existing weather file results in greater lake drawdown, the existing weather conditions from 6/18/1954 to 7/18/1954 will continue to be used for this analysis.M6.3 Weather File Creation for UHS Analysis After determination of the worst weather day and month and the worst net evaporation month, weather files are created for use in the UHS Analysis.PROJECT NO. 11333-297 CALCULATION NO.

SUMMARY

AND CONCLUSIONS The worst weather day and 30 days and worst net evaporation 30 days were determined by running LAKET over a range of days spanning from 1/1/1995 to 9/30/2010.

The worst weather day was determined to be 7/25/2001 ending at 6:00 AM, while the worst 30 day period of weather spanned from 7/21/1995 4:00 PM to 8/20/1995 3:00 PM. A comparison of this weather file with the existing weather file shows that the new weather file based on the weather data from 'PIALSL951O.txt' results in a higher maximum UHS outlet temperature than the existing weather file. Therefore the new weather files summarized in Table M6-3 will be used in the UHS analysis.For net evaporation, the worst 30 day period was determined to span from 6/13/2002 10:00 PM to 7/13/2002 9:00 PM. Comparison of this 30 day span with the previous limiting 30 days, 6/18/1954 to 7/18/1954, shows that the 1954 span remains bounding.Therefore, the existing worst 30-day net evaporation weather file will be used in the UHS analysis.PROJECT NO. 11333-297 CALCULATION NO.

L-002457 REVISION NO. 8 ATTACHMENT N, PAGE N3 of N20 N1.0 PURPOSE The purpose of this attachment is to evaluate the methodology in the LAKET-PC program and compare it to accepted methods for analyzing UHS cooling ponds. The LAKET-PC method is compared to NUREG-0693, "Analysis of Ultimate Heat Sink Cooling Ponds," [Ref. N5.1]. This evaluation reviews the individual equations for heat transfer, wind characterization, and evaporation used in both the NUREG document and the LAKET-PC program.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT N, PAGE N4 of N20 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT N, PAGE N4 of N20 N2.0 METHODOLOGY NUREG-0693, "Analysis of Ultimate Heat Sink Cooling Ponds" [Ref. N5.1] presents a method for analyzing the performance of ultimate heat sink cooling ponds. It was published in November 1980 and contains the accepted methodology for characterizing the thermal performance of cooling ponds.The methodology of LAKET-PC is compared to NUREG-0693 based onl review of the LAKET-PC manual [Ref. N5.2]. The equations for heat transfer, wind characterization, evaporation, and the iterative method are compared between both documents.

LAKET-PC is validated in the process of demonstrating that the method of calculation is equal to the approved method outlined in NUREG-0693.

N2.0.1 Lake Stratification

-NRC RAI #6 [Ref. N5.4] asks for additional information about the effects of thermal stratification of the lake.A method for determining if a lake is stratified is presented in Sargent & Lundy standard MES-11.1 [Ref. N5.7]. This method consists of assuming the lake is stratified with the less dense hot water floating on top of the slightly more dense colder water. If the calculated value for the upper layer depth is close to or beneath the actual lake bottom, then the lake can be regarded as not stratified.

The depth of the upper layer hot water is determined using Eq. 1.FiQ2D_3L 1/h,, 14gfATB -(Eq. N2-1)Where: fi -Interfacial shear coefficient, estimated as one-half of bottom friction coefficient fi = 0.5

If the volume of the lake below the upper layer depth is small compared to the total volume of the lake, then a plug flow model such as LAKET should be valid. When the volume below the upper layer depth is greater than one half the total volume of the lake, a different model that accounts for stratification should be used.N2.1 Acceptance Criteria N2.1.1 Acceptance Criterion N I -The calculation method in LAKET-PC for analysis of the thermal performance of cooling ponds shall be consistent with the accepted methodology presented in NUREG-0693, "Analysis of Ultimate Heat Sink Cooling Ponds" [Ref.N5.

PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT N, PAGE N9 of N20 N6.0 EVALUATIONS N6.1 LAKET-PC Background LAKET-PC is a one-dimensional thermal prediction model first written in 1976 which has been well established in many areas of cooling lake sizing and analysis.

The lake simulation model is used to yield water surface temperature as a function of position and time. The inherent assumptions used in the LAKET-PC model are as follows: 1. Thermal One Dimensionality

-A one dimensional model assumes that the temperature is constant at any point along the plane perpendicular to the direction of flow. There are neither cross-stream variations nor thermal stratification with respect to depth.2. Time Increment

-The calculation scheme in LAKET-PC is an iterative process, where the calculation interval can be set to increments of minutes or hours. Weather data input to the model is generally hourly, and so weather data is held fixed for intervals smaller than one hour.3. Fluid Interactions

-The simulation model used in LAKET-PC involves adjacent fluid masses at different temperatures.

The horizontal heat conduction due to this temperature difference is assumed to be negligible with respect to the heat rejection at the air / water interface, and is ignored. Similarly, conductive heat loss and frictional retardation at the water / channel interface are ignored.4. Lake Rectanaularization

-The one-dimensional model assumptions coerce the water body into an idealized rectangular channel. The length of this channel is the flow path length of the actual water body, while the width and depth are computed theoretical values.5. Global Flow Components

-LAKET-PC assumes that all secondary water gains and losses, such as makeup, blowdown, and runoff are distributed globally over the entire lake surface. This is a reasonable assumption for the majority of applications; an actual configuration in which component flow is known to exert a disproportionate local influence will not be modeled accurately on that local scale. However, the net result of the component will be correctly modeled.The movement of fluid through the one-dimensional channel is envisioned as a series of individual, distinct fluid segments.

Each segment has an individual length and temperature, while the width and depth remain constant for all. The channel thus fornms a queue of fluid segments, where additions are made at the inlet, and deletions are made at the outlet. This is referred to as a "first in, first out" queue. Any segment that enters the channel will cause an equal amount to be expelled at the outlet. The program assumes that all segments are uniform in temperature, and each segment is allowed to react independently with the environment.

PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT N, PAGE N10 of N20 N6.2 Heat Transfer Model This evaluation only considers the thermal model utilized in calculating the lake surface temperature, and does not delve into the effects of precipitation, makeup, blow down, or calculation of total dissolved solids.A) Edinger and Geyer Equilibrium Temperature Heat Transfer Model Both NUREG-0693 and LAKET-PC present thermal models in which the surface temperature of the cooling pond is calculated, as the bulk heat transfer modeled in these equations occurs at the water / air surface boundary.

Both thermal models utilize the Edinger and Geyer "Equilibrium Temperature Heat Transfer Model." The equilibrium temperature is defined as the water surface temperature at which the lake is in thermal equilibrium with the environment.

At this temperature, the heat removal from the water balances the heat addition, and the net effective heat transfer at the air / water surface is zero. Thus, the equilibrium temperature at any given time is a function only of the current meteorological environment.

This is not to be confused with the "natural" lake temperature used in LAKET-PC, which is the instantaneous water temperature in response to the meteorological parameters.

The equilibrium temperature is the theoretical steady state solution, while the natural temperature is the actual transient thennal response to the weather conditions.

The equilibrium temperature is used to define the heat transfer (Q) per the following equation: Q Ts JdQ = JK dT 0 E where Q = net heat transfer into the water (BTU/ft 2 day)E = equilibrium temperature

('F)T, = water surface temperature (fF)K = equilibrium heat transfer coefficient (BTU/ft 2 day 'F)Note that for this equation, K is assumed to be constant.

However, when evaluating ultimate heat sinks, which accept high heat loads, the external heat load rejected to the pond will increase the surface temperature significantly higher than the equilibrium temperature.

Thus, this equation is an iterative process in which the lake surface temperature is co-dependent on the net heat transfer rate and the heat transfer coefficient.

The surface temperature and heat transfer coefficient is held constant for each time step iteration when calculated in LAKET-PC.PROJECT NO. 11333-297 CALCULATION NO.

L-002457 REVISION NO. 8 ATTACHMENT N, PAGE N12 of N20 C) Wind Function NUREG-0693 The wind function (F(w)) is used to characterize the effect of wind on the evaporative heat loss from the water.The simple thermal model presented in NUREG-0693 utilizes a form of the wind function developed by Brady, which is solely dependent on the wind speed.FB(w) = 70 + 0.7W 2 where FB(w) = Brady wind function (BTU/ft 2 day/mrnHg)

W = wind speed measured 18-ft above the water surface (mph)However, Section 2.3 of NUREG-0693 discusses possible over-conservatism in this wind function and also presents an alternative equation.

The Brady wind function, presented above, seems to underestimate the evaporative heat flux. Another approach presented by Patrick Ryan in MIT Report No. 161 [Ref. N5.3] and summarized in NUREG-0693 includes the temperature dependence of the water surface when calculating evaporative heat loss. This Ryan function is less conservative than the Brady function, but based on firmer physical grounds. The Ryan function presented in NUREG-0693 is as follows: FR (w)=22.4rrTs

+ 460 F1'4 + 460 + 14W 0.378e, 0.378e,, P P where FR(w) = Ryan wind function (BTU/ft 2 day/mrnHg)

P = atmospheric pressure (mmHg)W2 = wind speed measured 2 meters above the water surface (mph)A comparison of calculations utilizing each of these two wind functions is shown in Fig.N6-1 in Section N6.3.LAKET-PC LAKET-PC uses two different wind speed functions, one for natural evaporation off a pond at its natural temperature, and another for the forced evaporation off a heated pond with elevated surface temperatures.

This is done to capture the effect of different phenomena above forced and natural water surfaces.

Both wind functions are taken from MIT Report No. 161 [Ref. N5.3].The wind speed function for a natural lake is solely dependent on the wind speed: FLH (W) = 17W, PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT N, PAGE N13 of N20 where FLH(W) = Lake Hefner wind function (BTU/ft 2 day/mmHg)

[Ref. N5.3]Additional heat rejected to the cooling pond will increase the temperature of the water surface, and introduce the effect of free convection due to the temperature differential between the water and the air. Consistent with NUREG-0693, LAKET-PC utilizes the Ryan wind function (F,.(w)) to account for free and forced convection when the surface of the water is at an elevated temperature.

Specifically, LAKET-PC utilizes the Ryan wind function when the surface temperature is 2.5°F higher than the natural temperature of the lake.N6.3 Comparison of Calculation Methods There are several simplifying assumptions made when generating the set of equations used for the heat transfer model defined on page 9 of NUREG-0693

[Ref. N5.1]. This includes the approximation that the heat transfer from the back radiation and atmospheric radiation effectively cancel each other out. The model presented in NUREG-0693 also utilizes the Brady wind function (FB(w)), which is solely a function of wind speed.However, Figure 2.4 in NUREG-0693 (reproduced below) presents the results from a hypothetical one square foot section of a pond surface subject to constant meteorological conditions utilizing varying levels of rigor in the calculations and wind functions.

The evaporative heat flux is calculated using the equation given in Table N6-1: QE = (es -e,4) F(W)Note that the equation above shows that given a constant water temperature, a decrease in atmospheric pressure will result in a slightly increased heat flux.

('F)Fig. N6-2: Evaporative Heat Flux Calculation Results 150 Fig. N6-2 shows that the Ryan wind function (which accounts for forced evaporation due to elevated pond temperatures) results in significantly higher evaporative heat flux values at elevated water temperatures.

As UHS cooling ponds are expected to see significant heat rejection, the surface temperatures will be notably higher than the natural lake temperature and thus, accounting for this effect when calculating evaporation is necessary.

The results in Fig. N6-2 are consistent with the results presented in NUREG-0693, shown in Fig. N6-1. The differences in evaporation calculated with either of the two wind functions are negligible for lightly loaded cooling ponds (where the lake temperature is relatively close to the natural lake temperature).

However, when the heat rejection to the pond is increased and the resulting water temperature increases significantly beyond the natural lake temperature, the effect of the Brady vs. Ryan wind functions becomes apparent.

The increased evaporative heat flux shown in Fig. N6-2 will result in lower water temperatures, as shown by Cases c) and d) in Fig. N6- 1.N6.4 Lake Stratification The calculation of the upper layer depth was done for the UHS at LaSalle in order to detennine the degree of stratification.

The following table shows the calculation of the upper layer depth, which is done according to the methodology presented in Section N2.0. 1. This calculation is done for varying values of temperature rise through the plant since this value changes significantly during the first few hours following an accident.The temperature difference between the upper and lower layers is calculated as the PROJECT NO. 11333-297 CALCULATION NO.

SUMMARY

AND CONCLUSIONS The methodology used in LAKET-PC is entirely consistent with the thermal model presented in NUREG-0693 and the wind speed functions presented in MIT Report No 161, which is also referenced and cited in NUREG-0693.

The use of the Ryan wind function (LAKET-PC) over the Brady wind function (NUREG thermal model) results in lower lake temperatures.

This is due to the fact that the Ryan wind function accounts for the effect of forced evaporation at water temperatures significantly higher than ambient air temperatures.

However, NUREG-0693 fully endorses the use of the Ryan wind function as a more accurate, although less conservative, method for calculating evaporative heat flux. Thus, Acceptance Criterion N I is met.In Table N6-4, it is determined that the fraction of lake volume below the calculated upper layer depth is 47%. Acceptance Criterion N2 requires that the lake volume below the upper layer depth be less than 50% for the lake to be considered not stratified.

Therefore, Acceptance Criterion N2 is met.PROJECT NO. 11333-297 CALCULATION NO.

This attachment includes analysis for only the Current Licensed Thermal Power (CLTP) (3559 MW,).Revision 7 included analysis for both CLTP (3559 MW) and Extended Power Uprate (EPU) (3998 MW,)power levels. Since Revision 7 plans for EPU have been cancelled, therefore only the CLTP power level is analyzed in this attachment.

The results in Revision 7 remain conservative as they utilize a more conservative UHS heat load than used in Revision 8. Rev. 8 shows that the acceptance criteria are met using Rev. 2 of Reg. Guide 1.27 [Ref. 05.8].The results of this attachment serve as an update to the current UHS design basis at LaSalle. See Section 1.1 of the main body of this calculation for further description on the history of this calculation.

PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT 0, PAGE NO. 02 of 042 02.0 METHODOLOGY AND ACCEPTANCE CRITERIA The Sargent & Lundy (S&L) LAKET-PC computer program [Ref. 05.2] is utilized to determine the combined impact of decay heat, initial UHS temperature, and allowable sediment accumulation in the UHS. Based on the allowable UHS initial temperature (Design Input 04.5), the maximum UHS temperature is determined for average sediment accumulations of zero (0), six (6), twelve (12), and eighteen (18) inches.02.1 Worst Weather File Creation 02.1.1 Regulatory Guide Criteria Reg. Guide 1.27, Rev. 2 [Ref. 05.8] describes a method for considering meteorological conditions in the design of the UHS. A synthetic weather file is created using weather data from the critical time period due to design of the UHS (33-45 hours for the LaSalle UHS), the worst 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and the worst 30 days. The synthetic weather file can be combined in this order, or alternatively the worst consecutive day period of the sum of these times can be used as the design basis. This calculation explores both options, each starting with the worst critical time period corresponding to the UHS transit time. For the LaSalle UHS, the critical time period unique to the design of the UHS is the transit time, which depends on the level of sedimentation.

The transit time is -33 hours, -39 hours, -42 hours, or -45 hours for 18 inches of sedimentation, 12 inches, 6 inches, and 0 inches, respectively (see Section 06.3).02.1.2 LAKET-PC Model for Weather Screening In order to find the worst weather periods, a specific UHS model was created in LAKET-PC with a transit time corresponding to the three hour time step period. The model is open cycle, which means water exiting the lake is discarded and new water enters the lake at predetermined conditions independent of the existing lake conditions.

The UHS is set to the same initial temperature at the beginning of each three hour time step. Since initial conditions are the same for each time step, there are no residual effects due to the weather from the preceding time step. The UHS outlet temperature for each 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> period corresponds to the environmental effects on the UHS during these three hours. From these results, it can be concluded that higher U-S outlet temperatures represent worse (hotter) weather conditions.

The LAKET-PC models 'Worst Weather I l0.dat' and 'WorstWeather 120.dat' were used to find the worst weather based on a UHS initial temperature of 1 10°F and 120'F, respectively.

The weather file analyzed is 'PIALSL95 I 0.txt', which is documented in Attachment M of this calculation.

The weather data spans from January 1995 to September 2010. 'WorstWeather_

10.dat' and'WorstWeather_

120.dat' are based off the input file 'WorstWeather.dat', which was developed in Attachment M of this calculation to determine the worst meteorological conditions based on an initial UHS temperature of I 00'F. The following changes were made to 'WorstWeather.dat' for the new input files:* 'WorstWeather_10 O.dat' changes from 'WorstWeather.dat':

o Lake initial temperature set to II 0°F o TPRISE (plant discharge water temperature) parameter set to 110.0°F" 'WorstWeather_120.dat' changes from 'WorstWeather.dat':

o Lake initial temperature set to 120°F o TPRISE (plant discharge water temperature) parameter set to 120.0°F PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT 0, PAGE NO. 03 of 042 The worst weather with an initial UHS temperature of 110°F and 120'F is considered since the approximate average temperature of the flow from the plant input to the UHS over the first several days following an accident falls between these temperatures.

Additionally, these temperatures ensure that the Ryan wind function is used throughout the entire weather screening since they remain greater than 2.57F above the natural lake temperature at all times.The results from 'Worst Weather_ I I0.dat' and 'WorstWeather_

I 20.dat' can be used to determine the worst weather over any time period using a similar methodology as outlined in Section M2.0 of this calculation.

The rolling average of the lake temperature over the time period in which the worst weather conditions are being determined is calculated for each time step. The time periods with the highest rolling average are considered to have the worst weather. These periods of time are applied to the design event in order to determine the period that results in the highest UHS temperature.

A synthetic weather file is created using the worst weather time periods that are required for each case as outlined in Table 02-2.02.1.3 Lake Area and Volume -The lake area and volume remains unchanged from that described in Section 12.1.2 in Attachment

A summary of the initial lake levels is provided in Table 02-1, below.Table 02-1: Initial Lake Level Sediment Lake Effective Effectiv Level Elevation Area Volume Area e Level(ft) (acre) (acre-ft) (acre) (acre_____I-_ -]__ (acre-ft)18-in 689.98 81.32 340.0 -1 47.08 215.59 12-in 689.98 82.12 380.5 47.55 241.24 6-in 689.98 82.96 422.1 48.03 267.64 0-in 689.98 83.80 463.5 48.52 293.89 The remainder of the drawdown curve (from a lake elevation of 689-ft through 685-ft) remains the same as given in Table 7.1 of the main body of this calculation with respect to the total lake volume and surface area. The effective volume and effective area are updated using the percentages determined in Attachment J (effective volume is 63.4% of total volume and effective area is 57.9% of total area).02.1.4 Plant Temperature Rise -The UHS heat load has been revised for this attachment to include the effects of the Residual Heat Removal (RHR) heat exchangers.

The new heat load on the UHS for CLTP operation is determined in L-002453 [Ref. 05.4]. The plant temperature rise is dependent on the UHS heat load, and the calculation of the new plant temperature rise is documented in Attachment P.02.1.5 LAKET Case Runs -There are several different types of cases that are run. These include the worst weather cases, the worst net evaporation cases, worst 33 hour3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> plus 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> plus 30 day cases, and diurnal wind exponent cases.A) Worst Temperature Cases -The worst temperature cases determine the maximum UHS outlet temperature based on an initial UHS temperature equal to the proposed Technical Specification (TS)temperature limits for the UHS (see Design Input 04.5). These cases determine if the UHS outlet temperature will remain below the limiting temperature of 107'F (see Design Input 04.1). Cases are run at varying start times due to the variable allowable UHS temperatures (see Design Input 04.5).I- PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT 0, PAGE NO. 04 of 042 B) Worst Net Evaporation Cases -The net evaporation cases use the same input file as the corresponding worst weather case, but are run with the most limiting 30-day net evaporation weather file. These cases are run at all levels of sedimentation.

The limiting weather file begins at 12:00 AM, so the initial temperature is set to the TS initial UHS temperature limit of 104.53'F (Design Input 04.5). The most limiting net evaporation weather was determined to be 6/18/1954 to 7/18/1954 in Attachment M, and this weather is used for the net evaporation cases in this attachment.

Additionally, sensitivity cases are run to determine the effect of changing the wind power law exponent.C) Worst 33 Hour -24 Hour -30 Day Cases -Rev. 2 of Reg. Guide 1.27 [Ref. 05.8] gives two alternatives for selecting the worst weather data. The first alternative consists of finding three critical time periods: 1)the time period in which the UHS will reach a maximum following a shutdown (for this case it is the UHS transit time), 2) the worst 1-day weather period, and 3) the worst 30-day weather period. These three time periods, which do not have to occur contiguously, are combined to produce a synthetic weather period.Alternatively, the worst 33-consecutive-day (transit time + I day + 30 days) weather period may be used as the basis for the worst weather period. For the LaSalle UHS, the consecutive 33 day period is chosen starting with the worst weather period corresponding to the UHS transit time.To determine which of these alternatives is most conservative, cases are run using both methods and the results are compared.D) Wind Sensitivity Cases -In the NRC Request for Additional Information (RAI) [Ref. 05.3], more information is requested regarding the diurnal effects of wind speed. This case determines the effects on the maximum UHS outlet temperature when considering a diurnal wind power law exponent based on the analysis performed in EC 394434 [Ref. 05.10]. Case Wind_375 is run to determine the results of adjusting the 375 feet wind speed at the meteorological tower to 2 meters above the UHS [Ref. 05.12]based on wind tunnel testing as documented in EC394434 [Ref. 05.10].A list of all cases run for this analysis is shown below: Table 02-2: List of LAKET Cases Sedimentation Start Case Name Time Period Level Time Weather File Worst Temperature Cases Case la _12AM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days 0 in. 0:00 WW_0-6.22.txt Case la_3AM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days 0 in. 3:00 WW_3-6.22.txt Case 1 a_6AM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days 0 in. 6:00 WW_6-6.22.txt Case la_9AM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days 0 in. 9:00 WW_9.txt Case 1a_12PM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days 0 in. 12:00 WW_12.txt Case la_3PM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days_1 0 in. 15:00 I WW 15.txt Case Ia_6PM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days 0 in. 18:00 WWI 8-6.22.txt Case la_9PM worst 45 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> + next 30 days 0 in. 21:00 WW_21-6.22.txt Case 2a 12AM worst 42 hours4.861111e-4 days <br />0.0117 hours <br />6.944444e-5 weeks <br />1.5981e-5 months <br /> + next 30 days 6 in. 0:00 WW_0-6.22.txt Case 2a 3AM worst 42 hours4.861111e-4 days <br />0.0117 hours <br />6.944444e-5 weeks <br />1.5981e-5 months <br /> + next 30 days 6 in. 3:00 WW 3-6.22.txt Case 2a_6AM worst 42 hours4.861111e-4 days <br />0.0117 hours <br />6.944444e-5 weeks <br />1.5981e-5 months <br /> + next 30 days 6 in. 6:00 WW_6-6.22.txt Case 2a_9AM worst 42 hours4.861111e-4 days <br />0.0117 hours <br />6.944444e-5 weeks <br />1.5981e-5 months <br /> + next 30 days 6 in. 9:00 WW_9.txt Case 2a_12PM worst 42 hours4.861111e-4 days <br />0.0117 hours <br />6.944444e-5 weeks <br />1.5981e-5 months <br /> + next 30 days 6 in. 12:00 WW_12.txt PROJECT NO. 11333-297 ICALCULATION NO.

LAKET-PC [Ref. 05.2] currently does not have the capability to simulate this mixing; however, the included lake effectiveness compensates for this effect by simulating the resultant stagnant lake areas caused by mixing. To provide additional assurance, the effect of UHS mixing is determined using LAKET-PC [Ref. 05.2] results with modifications made outside of LAKET-PC in Microsoft Excel [Ref. 05.5].The existing UHS thermal model consists of a plug type model developed in LAKET-PC [Ref. 05.2]. The simplified diagram of the LaSalle UHS model is shown on Figure 02.1. The model effective area and volume are 57.9% and 63.4% of their total values (see Attachment J).From Plant 1 Effective Volume/Area op To Plant Figure 02.1 -Existing UHS Model To simulate the effect of entrance mixing, the existing model is modified as shown in Figure 02.2. This new model is similar to the two stage model described in the MIT Report 161 [Ref. 05.7, Figure 3-9] as presented in Figure 02.3. The mixing zone with various sizes has been created outside of LAKET-PC[Ref. 05.2]. The discharge temperature out of the mixing zone is calculated for each time step (one hour)by assuming complete mixing of the plant discharge water and the mixing zone water. The effects of evaporation and other heat transfer are conservatively ignored. According to MIT Report 161 [Ref. 05.7, Section 6.5.1] the mixing region is typically small (<10% of the total area), therefore the two sensitivity cases are developed with 10% and 20% mixing zones. In these cases the mixing zone area/volume is subtracted from the nominal LAKET-PC model. For the purpose of the mixing zone sensitivity runs the 6AM case with 18" of sedimentation (Case 3a_6AM) is selected as the nominal case.I PROJECT NO. 11333-297 CALCULATION NO.

It is assumed that these percentages apply to the other sediment levels analyzed in this evaluation.

Since changes in sediment level change the depth of the lake evenly throughout the entire lake (see Section 6.2 of the main body of this calculation), the percentages of effective area and volume will negligibly change with sediment level.03.2 UHS Inventory for Fire Fighting -It is assumed that all UHS inventory for fire fighting is used immediately following an accident.

This is conservative as it decreases the volume of water in the UHS.03.3 UHS Transit Time -For weather sorting, the weather file is sorted in three hour increments.

For compatibility the transit time for 18-in, 12-in, 6-in, and 0-in of sedimentation is assumed to be approximately 33-hr, 39-hr, 42-hr, and 45-hr, respectively.

In Rev. 7, the spent fuel pool makeup flow was added to determine the total UHS seepage rate, but this is no longer added in Rev. 8 (see Section 06.2).04.3 UHS Inventory for Fire Fighting Following an Accident-Following an accident, 440,400 gallons of water from the UHS must be available for fire fighting [Ref. 05.1, Section 9.2.6.3].04.4 Anemometer Height -For the worst net evaporation weather data, which is from the Peoria weather data spanning from 1948 to 1996, the anemometer height is 20-ft (as taken from input files for the worst net evaporation cases in previous revisions).

For the worst weather data, which is taken from the LaSalle Station weather data spanning from 1995 to 2010, the anemometer is at a height of 33-ft (See Attachment K).04.5 Proposed TS Limits -The proposed TS temperature limits for the UHS for each of the event start times are provided in the proposed TS changes [Ref. 05.9]. These temperatures plus an uncertainty of 0.75'F are used as the initial UHS outlet temperature in the LAKET-PC model. Due to an initial iteration in the LAKET-PC code, the initial forced temperature input in the input file may differ from the values in Table 04-1.

The heat rejected to the UHS is determined for an operating scenario that considers a LOCA on one unit and a reactor SCRAM for the non-LOCA unit coincident with a loss of the cooling lake. Both RHR heat exchangers are in service for the LOCA unit. For the non-LOCA unit one RHR heat exchanger is in suppression pool cooling mode (and later shutdown cooling mode) while the other RHR heat exchanger is in fuel pool cooling assist mode.See Appendix P9.2 of Attachment P for the results of the plant temperature rise.06.2 Seepage Rate The seepage rate is determined from a UHS seepage of 0.2 ft 3/s (Design Input 04.2). Revision 7 included a constant flow of 600 gpm for spent fuel pool makeup (See Design Input 14.1). Instead of spent fuel pool makeup drawn from the UHS, the spent fuel pool is cooled through the use of the RHR heat exchanger[Ref. 05.4, Attachment D]. The heat load rejected by the RHR heat exchanger to the UHS is calculated in L-002453 [Ref, 05.4], and included in the plant temperature rise calculated in Attachment P. Therefore, no additional seepage flow is added to account for spent fuel pool makeup flow.06.3 UHS Transit Time The UHS transit time for each sedimentation level can be determined using the effective volume and the UHS flow rate. This calculation is shown in Table 06-1, below.Table 06-1: UHS Transit Time Calculation

Besides the 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, these time periods represent potential transit times for the LaSalle UHS depending on the level of sedimentation.

The time with the highest rolling average corresponds to the start time of the worst weather period over the time span that is under consideration.

Since LAKET-PC cases are made at varying accident start times and sedimentation levels, the worst weather periods are determined for various start times over multiple time periods. These results are shown in Tables 06-2 and 06-3.Table 06-2: Worst Weather Periods -I10'F Initial Temperature Start Time 24 Hour 33 Hour 36 Hour 39 Hour 42 Hour 45 Hour 12AM 6/23/09 8/18/95 8/18/95 8/18/95 8/15/95 8/18/95 3AM 6/23/09 8/18/95 8/18/95 8/18/95 6/22/09 6/22/09 6AM 7/24/01 6/22/09 6/22/09 6/22/09 6/22/09 6/22/09 9AM 7/24/01 6/22/09 6/22/09 6/22/09 6/22/09 8/17/95 12PM 6/22/09 6/22/09 6/22/09 6/22/09 6/22/09 8/17/95 3PM 6/22/09 6/22/09 6/22/09 8/17/95 8/17/95 8/17/95 6PM 6/22/09 8/11/10 8/11/10 8/14/95 8/17/95 8/17/95 9PM 6/22/09 8/11/10 8/14/95 8/14/95 8/14/95 8/14/95 Table 06-3: Worst Weather Periods -120'F Initial Temperature Start Time 24 Hour 33 Hour 36 Hour 39 Hour 42 Hour 45 Hour 12AM 6/23/09 8/18/95 8/18/95 8/18/95 8/15/95 8/18/95 3AM 8/18/95 8/18/95 8/18/95 8/18/95 8/18/95 8/18/95 6AM 7/24/01 8/18/95 6/22/09 6/22/09 6/22/09 6/22/09 9AM 7/24/01 6/22/09 6/22/09 6/22/09 6/22/09 8/17/95 12PM 6/22/09 6/22/09 6/22/09 6/22/09 8/17/95 8/17/95 3PM 6/22/09 6/22/09 6/22/09 8/17/95 8/17/95 8/17/95 6PM 8/11/10 8/11/10 8/26/95 8/26/95 8/17/95 8/17/95 9PM 8/11/10 8/26/95 8/26/95 8/14/95 8/17/95 8/14/95 In cases in which different worst weather periods are determined, the differences in the rolling average of the worst time periods are negligible.

For example, the rolling average of the 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> starting at 3AM on 6/23/2009 for an initial temperature of 1 lOF was determined to be 107.980'F.

For the 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> starting at 3AM on 8/18/1995, the rolling average is 107.9771F.

This is typical of all time periods in which the differing initial temperature causes a change in the worst weather period. Therefore, it is concluded that the 11 0IF and 120'F screenings produce essentially the same worst running average periods.In addition to determining the worst time span corresponding to the UHS transit time, it is also important to check for the worst weather for shorter time periods. It is possible that in screening based on transit time, a short span of bad weather can be missed if it is quickly followed by relatively mild weather.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT 0, PAGE NO. 014 of 042 Because of this, the worst weather periods for 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> and 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> have also been determined.

This ensures that the worst 9 hour1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> and 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> weather periods align with the initial accident heat loads exiting the UHS.06.4.2 Weather File Creation Weather files are created for each run based on the worst weather periods determined in Section 06.4.1.For the cases in Table 06-5, the worst weather file is created by inputting the worst 33 hour3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> time (the transit time for 18 inches of sedimentation) period as determined in Tables 06-2 and 06-3 plus the following 31 days.

The table below gives a summary of the start and end times used for creating the weather file based on a 33 hour3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> transit time.

This is only done for the 1 8-inches of sedimentation cases (approximately 33 hour3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> transit time), as these cases are expected to be the most limiting.

The results are shown in Table 06-6, below.Table 06-6: Worst Weather Comparison Case Start Time Initial Maximum Temperature Temperature 12AM Case 3a_12AM -6/22/2009 12AM 104.537F 104"53°F Case 3a_12AM-8.18 8/18/1995 12AM 104.53 0 F 104.53°F 3AM Case 3a_3AM 6/22/2009 3AM 102.72°F 105.757F Case 3a_3AM-8.18 8/18/1995 3AM 102.72°F 104.60-F 6AM Case 3a 6AM 6/22/2009 6AM 7 102.00'F 106.15-F Case 3a_6AM-8.18 8/18/19956AM L 102.00°F 103.72 0 F 6PM Case 3a-6PM 6/22/2009 6PM 104.75.F 104.75-F Case 3a 6PM-8.11 I 8/11/2010 6PM 104.75OF 104.75'F 9PM Case 3a 9PM 6/22/2009 9PM 104.75"F 104.75°F Case 3a_9PM-8.11 8/11/2010 6PM t 104.757F 10475°F As seen in the results of Table 06-6, the 6/22/2009 cases result in an equal maximum temperature (when the maximum temperature is the initial temperature) or higher maximum temperature for all time periods.Therefore, all cases will be run using the 6/22/2009 weather data as it produces the most limiting results.Cases with differing levels of sedimentation use the same weather files. This is acceptable since the weather files consist of the worst 33 hours3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> plus the following 31 days and any extra time needed to make the number of entries in the weather file a multiple of 24. Due to the extra time added after the 31 days, these weather files are the same for the longer transit times of the lower sedimentation cases.06.5 Comparison to 33-24-30 Case As described in Section 02.1.5., Rev. 2 of Regulatory Guide 1.27 [Ref. 05.8] gives two alternatives for selecting the worst weather data.To determine which of these methods is most conservative, cases were run using weather files created using both alternatives.

The UHS transit time for 18 inches of sedimentation is approximately 33 hours3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> (See Section 06.3). Therefore, a synthetic weather file period of 33 days is created consisting of the worst 33 hours3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> plus the worst 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> plus the worst 30 days.

The worst 30-day time period was determined in Attachment M. Three different cases are run, one starting at 9 AM and the other two starting at 6 AM.PROJECT NO. 11333-297 CALCULATION NO.

Since this is more conservative, the 33-consecutive-day weather period is used for the worst weather cases.06.6 Maximum Allowable Lake Temperature LAKET-PC [Ref. 05.2] is run to determine the UHS response to the heat load developed in Attachment P.Cases are run at four different sedimentation levels: 0 inches, 6 inches, 12 inches, and 18 inches. The time of day which the transient is assumed is critical when determining the maximum allowable initial temperature of the UHS. To account for the time of day at which the UHS transient may start, eight start times are used for all sedimentation levels.Each case is run with an initial temperature corresponding to the Technical Specification limits (see Design Input 04.5). Limiting weather data was determined in Sections 06.4 and 06.5, and the weather file dates are outlined in Table 06-5.

The most limiting case is 'Case 3a_6AM', which corresponds to 18 inches of sedimentation and an accident start time of 6AM.06.7 Maximum Net Evaporation Cases l c, 2c, 3c, and 4c are run to determine the maximum expected UHS drawdown at different sedimentation levels. These cases are run using the worst 30-day net evaporation weather period, which was determined to be 6/18/1954 to 7/18/1954 in Attachment M. The results of these cases are presented in Table 06-10.In addition to Cases I c through 4c, two additional cases were run to determine the sensitivity of the net evaporation to the wind power law exponent used by LAKET-PC [Ref. 05.2]. The power law equation is defined as [Ref. 05.2]: (Eq. 06-1)V1I ZI Where: v, = wind velocity at LAKET evaluation height (knots)V2 = wind velocity at anemometer height (knots)z, = LAKET evaluation height (2 meters = 6.562 feet)z, = Anemometer height (ft)a = Power law exponent The default exponent used when adjusting the wind from the anemometer height to the 2-meter height used in the LAKET-PC calculations is an exponent of 0.3 [Ref. 05.2]. The wind input to the weather file'30dayevap.txt' was altered to simulate an exponent of 0.1 in case 'NetEvap-0.

1' and an exponent of 0.2 in case 'NetEvap-0.2'.

The weather files with the adjusted wind speeds are 'NetEvap_0.1.txt' and'NetEvap_0.2.txt'.

These results are summarized in Table 06-10.Table 06-10: Worst Net Evaporation Cases Cas Weather..a Sediment I Initial Lake Maximum UHS Case Weather Data Level (in.) I Temp.

Please note that more limiting UHS drawdown of 2.27 would exist with consideration of inventory loss due to spent fuel pool makeup as documented in Section 17.1 of Attachment I. Reducing the power law exponent increases the UHS drawdown, but the change is relatively small.06.8 Wind Sensitivity Cases To determine the effects of a diurnal wind power law coefficient on the maximum UHS temperature, a weather file was created for a LAKET-PC run to incorporate the coefficients determined in EC 394434[Ref. 05.10]. The base weather case of 'WW_6-6.22.txt', provides wind speed values at a height of 33 feet. The adjusted wind speed at 2 meters was found using Eq. 06-1 and the power law exponents (a)from EC 394434 [Ref. 05.10]. These adjusted wind speed values were inserted into 'WW_6-6.22.txt' to create the new weather file, 'Diumal.txt'.

The LAKET-PC run 'Case Diurnal' was run to determine the maximum UHS temperature using the diurnal wind speed exponents.

For Case Wind_375, wind speeds were taken from EC 394434 [Ref. 05.10] as measured at an anemometer height of 375 feet. These wind speeds were multiplied by a wind speed ratio of 0.405, which is the calculated multiplier to adjust the wind speed from 375 feet at the meteorological tower to 2 meters (6.56 feet) above the UHS [Ref. 05.12]. These wind speeds were then converted to knots for entry into a LAKET weather file. These adjusted wind speed values were inserted into 'WW_6-6.22.txt' to create the new weather file, 'Wind_375.txt'.

The LAKET-PC run Case Wind_375 was then run with this weather file and the results are reported in Table 06-11.Table 06-11: Wind Sensitivity Runs Case Weather Data Sediment Initial Lake Maximum UHS Level (in.) Temp. (*F) Temperature

(°F)Case 3a_6AM WW_6-6.22.txt 18 102.00 " 106.15 Case Diurnal Diurnal.txt 18 102.00 105.08 Case Wind_375 Wind_375.txt 18 102.00 104.34.......,, ., .= I ....As seen in Table 06-11, the maximum UHS temperature from the diurnal case remains below the maximum UHS temperature of Case 3a_6AM, which uses a constant wind speed coefficient of 0.3.Therefore, the use of a constant coefficient of 0.3 is conservative.

The maximum UHS temperature of Case Wind_375 also remains below the maximum UHS temperature of Case 3a_6AM.06.9 UHS Mixing To determine the effect of mixing at the plant discharge into the UHS, several sensitivity cases were run in I PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT 0, PAGE NO. 020 of 042 LAKET-PC [Ref. 05.2]. These cases include a mixing region that is 10% the size of the UHS and a mixing region at 20% the size of the UHS. Microsoft Excel [Ref. 05.5] is used to calculate the temperature in the mixing zone, and LAKET-PC is used to calculate temperature for the remaining UHS.06.9.1 Non-Mixing Zone UHS Area and Volume -For these LAKET-PC runs, the area and volume of the UHS not in the mixing zone is needed. These values were calculated as 10% of the total UHS area and volume for the 10% sensitivity run and 20% of the total UHS area and volume for the 20% sensitivity run. The effective area is 57.9% and the effective volume is 63.4% as determined in Attachment J. The UHS drawdown curves for these cases are summarized in Table 06-12.Table 06-12: UHS Drawdown Curves for Mixing Zone Sensitivity Runs Total Area Total Volume Effective Area Effective Volume Elevation (acres) (acre-ft) (acres) (acre-ft)10% Mixing Region 689.98 73.19 306.00 42.38 194.00 689_ 71.78 234.72 41.56 148.81 688 70.34 163.71 40.72 103.79 687 26.73 91.98 15.48 58.32 686 20.00 54.00 11.58 34.24 685 12.08 39.42 6.99 24.99 20% Mixing Region 689.98 65.06 272.00 _ 37.67 172.45 689 63.80 208.64 36.94 132.28 688 62.52 145.52 36.20 92.26 687 -23.76 81.76 13.76 51.84 686 17.78 48.00 10.29 30.43 685 10.74 35.04 6.22 22.22 06.9.2 Mixing Zone Temperature

-The case 'Case3a_6AM.dat' is selected as the nominal case for the UHS mixing sensitivity runs. The temperature of the mixing zone is determined in Microsoft Excel, and then LAKET-PC is run to determine the impact on the UHS temperature in the non-mixing zone portion of the UHS. Multiple iterations of the LAKET-PC analysis are needed as these results are used in calculating the mixing zone temperature.

The change in the mixing zone temperature between time steps is input as the FPLANT variable in LAKET-PC.

Iterations are run until the desired convergence in the mixing zone temperature is achieved.Additional cases are run for 10% mixing starting at 9AM and 20% mixing starting at 12PM. This is to account for the reduced UHS transit time due to the reduced UHS volumes determined in Table 06-12.The Microsoft Excel [Ref. 05.5] equations used for the UHS mixing analysis are given in Appendix 08.2.I PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT 0, PAGE NO. 021 of 042 06.9.3 Results -The full Microsoft Excel [Ref. 05.5] results for the 10% mixing zone and 20% mixing zone cases are provided in Appendix 08.2. A summary of these results are provided in Table 06-13.Table 06-13: UHS Mixing Sensitivi Case Weather Data ty Runs Sediment Initial Lake Level (in.) Temp. (°F)6AM Cases Maximum UHS Temperature

For the 12PM case, the maximum UHS temperature occurs three hours following the accident.

The UHS discharge to the plant at this time has not been through the mixing zone, which accounts for the temperature being identical between the mixing and non-mixing cases. It is considered conservative to run the cases in LAKET without adjusting the results for a mixing zone at the inlet of the UHS.I PROJECT NO. 11333-297 1

CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT 0, PAGE NO. 022 of 042 07.0 RESULTS AND CONCLUSIONS 07.1 Maximum Allowable Lake Temperature Summary Table 06-9 provides a summary of the maximum UHS temperatures for the maximum allowable initial temperatures given in the Tech Specs (see Design Input 04.1). The highest UHS temperature is 106.15 from Case 3c_6AM, which corresponds to an accident start time at 6:00 AM and 18 inches of sedimentation.

This remains below the maximum allowable UHS outlet temperature of 107°F. Figure 07.1 shows the UHS inlet temperature and UHS inlet temperature over the 33 day worst temperature event for Case 3c_6AM.07.2 Maximum Net Evaporation Summary Table 06-10 provides a summary of the maximum lake drawdown for the worst net evaporation cases.These results show that there is a maximum UHS drawdown of approximately 1.5 feet occuring at a sedimentation level of 0, 6, or 18 inches. In addition, it is shown that there is a small increase in the UHS drawdown when the power law exponent for the wind speed adjustment is decreased.

Please note that more limiting UHS drawdown of 2.27 would exist with consideration of inventory loss due to spent fuel pool makeup as documented in Section 17.1 of Attachment I Figure 07.2 shows the UHS drawdown over the worst 30 days for net evaporation from Case Ic.07.3 Compliance with Acceptance Criteria 07.3.1 Acceptance Criterion

L-002457 REVISION NO. 8 ATTACHMENT P, PAGE P3 of P58 P1.0 PURPOSE The purpose of this attachment is to determine the Core Standby Cooling System (CSCS)temperature rise across the plant based on the new heat load to the Ultimate Heat Sink (UHS) determined in Revision 4 of L-002453 [Ref. P5.1]. This temperature rise is to be used in the LAKET-PC [Ref. P5.3] model of the LaSalle County Station UHS.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT P, PAGE P4 of P58 P2.0 METHODOLOGY The plant temperature rise is used in LAKET-PC [Ref. P5.3] to compute the rise in water temperature caused by the heat rejected to the UHS during the postulated accident.The total heat load rejected to the UHS is determined in Attachment D of L-002453 [Ref.P5,1]. The heat rejection rate is determined for an operating scenario that would maximize the heat load to the UHS. This scenario considers a Design Basis Loss of Coolant Accident (LOCA) on one unit and a reactor SCRAM on the non-LOCA unit coincident with a UHS design event (loss of the cooling lake) occurring 100 days after refueling of the non-LOCA unit. Both Residual Heat Removal (RHR) heat exchangers are in service to remove reactor heat on the LOCA unit. For the non-LOCA unit, one RHR heat exchanger is placed into suppression pool cooling mode (and later shutdown cooling mode), while the other RHR heat exchanger is placed into fuel pool cooling assist mode 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> after the initiation of the event.Once the total heat load rejected to the UHS is known, the temperature rise through the plant is determined by the following heat transfer equation: AT- Q (Eq. P3-1)where: AT = plant temperature rise ['F]Q = heat rejection rate to the UHS [BTU/hr]cP = specific heat capacity of water [BTU/(lbm-°F)]

In = mass flow rate [lbm/hr]The mass flow rate is determined by converting the Core Standby Cooling System (CSCS)volumetric flow rates of 65.3 ft 3/s and 86.0 ft 3/s (Design Input P4.2) to a mass flow rate at a density of 62.0 lbm/ft 3 (Assumption P3.1).P2.1 Computer Programs and Software The analysis performed herein utilizes Microsoft Excel 2003 [Ref. P5.4], which is commercially available.

The validation of Excel is implicit in the detailed review of all spreadsheets used in this analysis.

All computer nins were performed using PC No.ZD6661 under the Windows XP operating system. Excel Add-in function STMFUNC is used to calculate the thermal properties of water and steam at varying operating conditions

[Ref. P5.5]. The Excel Add-in finction STMFUJNC has been validated and approved for use in accordance with the S&L Quality Assurance (QA) program.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT P, PAGE P5 of P58 P3.0 ASSUMPTIONS P3.1 Water Properties

L-002457 REVISION NO. 8 ATTACHMENT P, PAGE P8 of P58 P6.0 CALCULATIONS P6.1 Total and Integrated Generated Heat Load Rejected to the UHS The total heat load rejected to the UHS following a LOCA for one unit and a reactor SCRAM for the non-LOCA unit is determined in Attachment D of L-002453 [Ref. P5.1].These values are integrated in order to determine the heat load rejected to the UHS over the entire event. The integration uses the average total heat load between the current time step and the preceding time step.Exceptions to this method occur at two separate time steps. One exception to this method is for the integrated heat load at 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />, which is when fuel pool cooling begins. The heat load rejected to the UHS increases at hour 16 due to inclusion of the fuel pool heat load. Therefore, at the 16 hour1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> time step only the UHS heat load from the preceding time step (15.21 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br />) is utilized for integration.

The other exception occurs at the 4.13 hour1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> time step. Sensible heat is rejected to the UHS until 3.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> (12,600 seconds) after the design basis event [Ref. P5.1]. To account for the sensible heat load rejected to the UHS between the 3.33 hour3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> and 4.13 hour1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> time step, the heat load at 3.33 hours3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> is conservatively used for the UHS heat load integration.

These results are presented in Appendix P9.1 for MUR PU and are used to determine the temperature rise through the plant. The equations used in Excel for this calculation are included in Appendix P9.3.P6.2 Plant Temperature Rise In order to facilitate the creation of a LAKET-PC [Ref. P5.3] input file, the plant temperature rise results are determined in one hour increments.

This requires linear interpolation of the integrated total generated heat load found in L-002453 [Ref. P5.1] to determine the integrated total generated heat load at hourly intervals.

The plant temperature rise is calculated in Excel using Eq. P3-1. The results of this calculation are shown in Appendix P9.2, and equations used in Excel are included in Appendix P9.3.PROJECT NO. 11333-297 CALCULATION NO. L-002457 REVISION NO. 8 ATTACHMENT P, PAGE P9 of P58 P7.0
