D Revy A Page 1 of 5 LSCS-UFSAR 9.2 WATER SYSTEMS The auxiliary water systems for the LaSalle County Station are as follows: a. CSCS equioment cooling water system, b. station service water system, c. reactor building closed cooling water system, d. demineralized water makeup system, e. potable and sanitary water system, f. ultimate heat sink, g. cycled condensate system and refueling water storage facilities, h. turbine building closed cooling water system (TBCCWS), i. primary containment chilled water system, j. station heat recovery system, k. suppression pool cleanup system, and 1. chemical feed system.9.2.1 CSCS Eauinment Coolina Water The function of the core standby cooling system-equipment cooling water system (CSCS-ECWS) is to circulate lake water from the ultimate heat sink for cooling of the residual heat removal (RHR) heat exchangers, diesel-generator coolers, CSCS cubicle area cooling coils, RHR pump seal coolers, and low-pressure core spray (LPCS) pump motor cooling coils. This system also provides a source of emergency makeup water for fuel pool cooling and also provides containment flooding water for post-accident recovery.

This CSCS-ECWS system is equivalent in purpose to the essential service water cooling systems at other stations.9.2.1.1 Design Bases 9.2.1.1.1 Safety Design Bases a. The system is sized based on the followinw minimum eciinment cooling water flow requirements:

D Rev: A Page 2 of 5 REV. 12 -MARCH 1998 9.2-1 LSCS-UFSAR 9.5.4.5 Instrumentation and Controls Fuel levels in each day tank and storage tank are indicated locally, and storage tank levels are also indicated at each storage tank filling station. `Ton-roI alarms annunciate high or low levels in each day tank and low level in each storage tank. All day tank level instruments and diesel-generator transfer pump controls are Seismic Category I and Class 1E. A local pressure indicator is connected to the discharge of each transfer pump to monitor pump discharge head.. A local differential pressure indicator is connected across the transfer pump suction strainer to identify a clogged strainer.Each diesel engine gauge panel includes local gauges for monitoring the following diesel-generator skid-mounted system fuel oil parameters:

fuel oil temperature, fuel pump suction strainer inlet and outlet pressure (Divisions I and 2 diesel generators only), fuel pump discharge pressure, fuel filter inlet pressure, and fuel filter outlet pressures (for the Division 3 diesel generators, filter inlet and outlet pressure gauges are mounted on the engine and not on the gauge panel). In addition, pressure switches are installed in the skid-mounted systems to annunciate high fuel filter differential pressure for the Divisions 1 and 2 diesel generators and low fuel pump discharge pressure for the Division 3 diesel generators.

The entire skid-mounted fuel oil system, including instrumentation, is supplied by the engine manufacturer as a part of the diesel engine.Each diesel-generator fuel transfer pump is started and stopped automatically by day tank level control switches.

The diesel fire pump fuel transfer pump is started manually; however, it is automatically shut down by day tank high level. -Elapsed time instrumentation monitors diesel-generator transfer pump running time and, when the diesel engine is operating, pump shutdown time. This instrumentation actuates control room alarm lights if pump running time is excessive or shutdown time is too short to permit remote detection of possible fuel oil leaks at the day tank or diesel generator.

9.5.5 Diesel-Generator Cooling Water System The function of the diesel-generator cooling water system is to transfer the heat rejected from the engine water jacket, the lube oil cooler and the engine air aftercooler to the CSCS equipment cooling water system (CSCS-ECWS).

9.5.5.1 Design Bases n 9.5.5.1.1 Safety Design Bases 0 0 Cooling capacity of this system is based on a diesel-generator output of 2860 kW with an environmental temperature of 1220 F to maximum and a minimum and maximum lake water temperature of 320 F C and 1000 F, respectively.

Total heat transfer by this system is 9.5-34 REV. 0 -APRIL 1984 0 4 LSCS-UFSAR approximately 7.8 x 106 Btu/hr per diesel-generator set at rated engine capacity.

The diesel cooling water heat exchangers are sized based on operation of 110'% of rated load.8High water temperaLure is alarmed at 2000 F and the engine is automatically shut down if the cooling water temperature at the engine outlet exceeds 2080 F in order to prevent engine damage due to overheating.

This shutdown control is in effect only when the engine is started manually and bypassed when the diesel generator is started automatically during an emergency.

Heaters are installed in the cooling water piping below the lube oil cooler to maintain the engine water and lube oil in a warm standby condition while the engine is not operating; thus increasing the starting reliability of the diesel generator.

Natural convection is employed to circulate the warm engine water through the lube oil cooler during standby.Each system is designed based on Seismic Category I requirements and is protected from tornadoes, missiles, and flooding.9.5.5.1.2 Power Generation Desian Bases The diesel-generator cooling water system is not required during power generation.

Consequently, it possesses no power generation design bases.9.5.5.2 System Description Each diesel-generator cooling water system is a separate, independent closed loop system supplied with the diesel generator and located entirely on the diesel-generator skid. It consists of two parallel engine driven centrifugal circulating pumps, a low-pressure expansion tank, an AMOT temperature regulating valve, a lube oil cooler, and the engine cooling water heat exchanger.

The expansion tank is fitted with a 7 psig relief cap which also will relieve vacuum. Engine coolant is demineralized water treated with chromate, borate-nitrite, or silicate-nitrite type corrosion inhibitors in accordance with the engine manufacturer's recommendations.

During operation, cooling water at a flow of 1100 gpm per diesel-generator set is circulated by the engine driven pumps through the diesel engine cooling water passages to the lube oil cooler, through the temperature regulating valve, and then to the engine cooling water heat exchanger.

See Figure 9.5-5 for additional details.'In 'r 0%The engine cooling water heat exchanger is a two-pass shell and o tube type heat exchanger having admiralty tubes with a carbon steel water box and shell. Engine cooling water is circulated through the shell side while strained lake water is pumped U a through the tube side by the CSCS-ECWS (Subsection 9.2.1). CO Design pressure and temperature is 150 psig and 3000 F for both ou 9.5-35 REV. 0 -APRIL 1984 '0, P. -

LSCS-FSAR AMENDMENT 29 JANUARY 1978 QUESTION 040.92"In response to Question 040.16 you have provided in section 9.5.5.1.1 a total diesel generator cooling water heat rate of approximately 6.15 million Btu/hr.This heat is rejected in the heat exchanger interfacing with CSCS equipment cooling W.ýater system when the diesel generator is operating at rated capacity.

Also, in section 9.5.5.2 you mention *that the cooling waterflbw rate in the diesel engine is 1,100 gpm. It is not clear whether these heat and flow rates are for the total five diesel generators or for a single diesel generator.

Please provide the heat and flow rates for each of the five diesel generators.

In addition, also provide the design temperature differential((OF) for each diesel engine cooling water when operating at rated capacity."

There are no assumptions for this revision.Inputs:* Cooling water temperature

= 107 OF (Reference 2)* Air temperature

= 148 OF (Reference 1)* Water flow rate = 72.5 gpm (Reference 1)* Air Flow rate = 23,760 cfm (Reference 1)* Fouling factor = 0.02650655 hrft 2 e.F/BTU (design fouling factor) (Reference 1)* 1 tube plugged (5% tube plugging) (Reference 1)

Method of Analysis / Numeric Analysis: The existing heat exchanger model will be revised by changing the input of the "Tube Inlet Temp" from 104 OF to 107 OF. Because the fan for the 1(2)VY03A cooler is at the exit of the cooler, the inlet air flow for the front cooler A is iterated until the flow rate at the exit of the last row of the cooler is approximately 23,760 cfm. The iteration process is detailed in section 6.7 of revision B. The air flow values can be found on pages A9 for the case that was considered.

Conclusions:

The 1(2)VY03A coolers can remove the design heat load of 722,217 BTU/hr with the following conditions:

• 107 OF cooling water temperature a 148 OF air temperature

• design fouling factor of 0.02650655 hr-ft 2-°F/BTU* 1 tube plugged* air flow rate of 23,760 cfm* water flow rate of 72.5 gpm The total heat removed at these conditions is 757,712 BTU/hr, which provides 4.9% thermal margin over the design heat load. This thermal margin is enough to account for the 4.5% model uncertainty shown in Attachment J and is acceptable.

Note that a maximum fouling factor was not calculated as was done in previous revisions because it is not practical to set up test conditions that would allow accurate measurement of the fouling factor for these heat exchangers.

The bounding fouling factor is the design fouling factor of 0.02650655 hr.ft.F/BTU.

This case is shown in Attachment A.Attachments:

DESIGN INPUTS The thermal performance model is developed using PROTO-HX T M , Version 3.01. PROTO-HXTM was developed and validated in accordance with Proto-Power's Nuclear Software Quality Assurance Program (SQAP). This program meets the requirements of IOCFR50 Appendix B, I OCFR2 1, and ANSI NQA- 1, and was developed in accordance with the guidelines and standards contained in ANSII[EEE Standard 730/1984 and ANSI NQA-2b-1991.

PROTO-HXTM Version 3.01 was verified and approved for use as documented in Reference (1).The design inputs for this calculation consist of the heat exchanger design basis performance requirements (Table 1), performance specifications (Table 2) and construction details (Table 3)provided by the heat exchanger manufacturer data sheet (Attachment A) or other design documents as referenced.

Construction details give the necessary information for model construction while performance specifications are used to benchmark the model.VY cooler thermal performance in this calculation will be assessed only with respect to the nominal accident conditions (i.e., design basis LOCA) with no tubes plugged. Condensing modes of operation and tube plugging margins are not addressed.

Calculation 97-199 Revision B02 Page 2a of 24 Insert A: The basis for the -0.4 in.-w.g. atmospheric pressure in Table I in Rev. AO was Ref. 4 UFSAR Table 3.11-8, provided in Attach. A. This value is used in determining the coil pressure value to be used in the Proto-HX thermal model. The -0.4 in. w.g. in this UFSAR table has subsequently been revised and is now 0 in. w.g. Nevertheless, as discussed on pgs. 9 and 12 of Calculation L-002511 Rev. 0, and as verified in Passport D071 panel for reactor building (RB) HVAC differential pressure controllers 1(2)PDC-VR007, the nominal value is still -0.4 in. w.g. Under abnormal conditions, the reactor building is maintained at least -0.25 in. w.g. by the Standby Gas Treatment System (VG), however there is a short period of time before VG starts during which RB pressure may approach 0 in. w.g. If both VG trains are operating, the pressure could reach a minimum of -0.69 in. w.g. until one train is secured. Recent surveillance test data (WO #727706 for Secondary Containment Leak Rate Test LTS-300-3) indicates with one train of VG in operation for at least 5 minutes, the refuel floor RB pressure averaged approx. -0.4 to -0.5 in. w.g.) In conclusion, the -0.4 in. w.g. pressure is still a reasonable value to use in conjunction with Proto-HX thermal performance evaluations.

Slight variations, e.g. a difference of 0.4 -0.25 = 0.15 in. w.g., equates to a pressure difference of 0.005 psig (see bottom of pg. 14/24 of Calculation.97-199 Rev. A).For purposes of comparison, the Proto-Power Corp. (preparer/approver of Rev. A of the calculation) was contacted and the LaSalle Proto-HX model for 1(2)VY03A was run for two cases. Both cases used the same input parameters and extrapolation conditions, with the exception of the atmospheric pressure extrapolation condition.

One case used an atmospheric pressure of 14.329 psig corresponding to 0.0 in. w.g. differential pressure in the cooler room, and one with 14.315 psig corresponding to the -0.4 in. w.g. differential room pressure.

As expected based on discussions with the DEM HVAC engineer, these runs demonstrated that the calculated heat removal rate was essentially unchanged (calculated was actually slightly higher at the higher room pressure, however the difference was insignificant (0.1% higher)).

Given the available heat transfer margin, small differences in ambient room pressure are therefore considered insignificant.

Per Revision B02, Reference 4 has been changed to calculation L-002511 Rev. OA to provide the basis for the -0.4 in, w.g.

The maximum available heat removal rate is calculated using the benchmarked PROTO-HXTM model and the inlet conditions defined in Section 6.7 with zero fouling. By comparing the available heat removal rate calculated with zero fouling (qciann) to the required heat removal rate, the maximum available margin is determined.

CONCLUSIONS A model for the LaSalle County Station Units 1 & 2 SE Cubicle Area Coolers was developed using PROTO-HX T M Version 3.01. The model was benchmarked and validated using the performance specifications provided by the cooler vendor. The close correlation with vendor specified and model predicted thermal performance confirms that the models are to be considered acceptable for use in the GL 89-13 heat exchanger testing program and related performance analyses.The available thermal margin for the coolers has been defined for the nameplate rated flow of 180 gpm and for a reduced flow rate of 72.5 gpm in support of service water system re-balancing efforts. Inclusion of a conservative assessment of the uncertainty in the analytical methods of PROTO-HXTM has provided high confidence in the thermal margins defined by the model for all cases.The model database is saved under file name vy-03a.phx, with a file size of 1,277,952 bytes, and a file date and time of 7/6/98 at 6:21:52 pm. The saved database is set up to run the 72.5 gpm case with adjusted design fouling factors of 0.002 air-side and 0.002 tube-side.

feed system which will treat the service water tunnel; flow-with oxidizing biocides.

However, the chemical feed' ..system should not be considered auxiliary equipment required for~ the CSCS-ECW systems to perform their function.

Therefore, the I operability of the-CSCS-ECW systems should not be tied to the operability-of the chemical f eed system. connections and isolation valves are also provided immediately upstream and downstream of each cooled component for injection and circulation of biocidal agents, if necessary.

e. To detect leakage of radioactivity to the environment, radiation monitors are installed in the CSCS-ECWS immediately downstream of cooled components that contain radioactive fluids. The CSCS-ECWS discharge lines from these components are capable of remote manual isolation from the main control room.f. Design of system piping and components is based on a 40-year life.Exterior surfaces of all buried system piping is protected by bituminous coatings and wrappings and provisions for cathodic protection are installed where such protection is found to be required based on electrical potential measurements.

Calculation No.97-199, Rev. B301 Page3 of_4-Purpose/Objective The purpose of this minor revision is to assess the following:

1) the impact of error"flag" message on the printouts of Proto-Hx, which states that the Air Side Reynolds number is outside the range of equation applicability.

An example of this flag can be found on Attachment G, page 4. 2) the "Data Report" output for the air coolers (example Attachment G, page 2) indicates a LOG (base 10) in the Fin Configuration equation for the Colburn 'j' factor, however Equation 9 of this calculation shows this as the natural log (Ln).Methodology and Acceptance Criteria N/A, this is an assessment of the current calculation.

Assumptions I Engineering Judgments Assumptions and engineering judgements are documented within this analysis.Design Inputs N/A, this minor revision utilizes those of the current calculation.

Thomas, 2 nd Ed., 1999.Analysis 1) On page 13, the Colburn 'j' factor versus Reynolds Number (Re) relationship is given.This relationship was derived in this calculation to more closely match the manufacturer's heat transfer capability.

The Colburn 'j' factor relationship is based on the information in Attachment D. This attachment shows the straight line relationship between the 'j' factor and Re number when plotted on a log-log scale, with Re number end points between 1000 and 8000. This relationship was used to derive Equation 9, which is input into the computer model with the two end points. Even though the calculated Re is less than 1000 in some cases (it is normally in the range of approx. 800 to 1000), the program still uses the Equation 9 relationship with the actual Re. The computer program in this case is flagging that it had to extrapolate past the 1000 end point it was given. Reference 2, page 553 shows this relationship to be linear down to a Re of 600 for a similar type of finned tube. Based on engineering judgement, it is therefore reasonable to extrapolate this line to a somewhat lower Re down to a Reynolds number of approximately 800. Thus the results of the calculations are acceptable.

2) Equation 9 in the body of the calculation, which indicates Ln, is correct and Ln is the function being used by the program. A check of the j' factor numbers indicated on the computer output in the calculation show that the program is using the natural log Ln.The program manufacturer, Proto-Power, was contacted on 4-03-02. They indicated that the LOG on the Data Report represents indefinite text output and they confirmed Calculation No.97-199, Rev. BOI Page 4 of 4-that the program is indeed using the natural log (Ln) function for its calculations. (A letter/fax was obtained from Proto-Power on 4-03-02 confirming this discussion.

The fax has been assigned file number SEAG 02-000086).

A copy of this letter is attached (see Attachment A of this minor revision.Summary and Conclusions Based on the above discussion, the calculation results are acceptable as-is.

Subject:

PROTO-HX Air Coil Module Brian, The PROTO-1IX Data Sheet Output Report for Air Coils shows the equation for"Configuration (for Air-Side h)" with the "LOG" term in the equation.

This in fact represents the "Natural Log" and not "Log Base 10." The equation actually uses the Natural Log (LN) term, however, the output report is ambiguous in printing "LOG".If you have any other questions.

BOO PAGE NO. 4 of 6 1.0 PURPOSE/OBJECTIVE The purpose of this minor revision is to revise the thermal model of the B & C RHR Pump Room Coolers (1VY03A, 2VY03A) for a 104°F Service Water inlet temperature.

This assessment will evaluate the adequacy of these heat exchangers during a maximum allowable inlet service water temperature of 104*F. Also a maximum design fouling factor will be determined.

2.0 METHODOLOGY AND ACCEPTANCE CRITERIA The existing heat exchanger model will be revised by changing the input of the "Tube Inlet Temp." from 100 0 F to 104OF and simulated for the following conditions:

design fouling factor and design fouling factor with 5% of the tubes plugged. The acceptance criteria will be for the thermal margin at each stated condition to exceed the LaSalle design heat load of 722,217 BTU/hr (Ref. 1, table 1). Additional conservatism was built into this acceptance criteria by assuming a 5% uncertainty in the Proto-HX heat transfer calculations.

The original benchmark model developed for this heat exchanger demonstrated a correlation to vendor performance specification well within this assumed 5% margin. In addition, as analyze within Reference 2, a sensitivity run will be performed with a 10% degraded airflow allowance at a service water inlet temperature of 104 0 F and a 5% plugging allowance.

A final case will be evaluated which determines the maximum acceptable fouling factor at which the design heat load can be accommodated including heat transfer model uncertainty and a 5%tube plugging allowance (w\ design airflow).3.0 ASSUMPTIONS I ENGINEERING JUDGMENTS The assumptions indicated in section 5.0 of References 1 and 2 are still valid.4.0 DESIGN INPUTS The design inputs consist of References 1 and 2 listed below.

BOO PAGE NO. 5 of 6 6.0 CALCULATIONS The current calculation model is based on a Service Water inlet temperature of 100 0 F with a varying cooling water flow rates. Based on Reference 1 Calculation, the limiting flow rate for this unit is 72.5 gpm. At this flow rate, temperature and at an assumed fouling factor of 0.03734207 hr*ft 2*OF/BTU, the amount of heat transferred is 938,124 BTU/hr compared with a LaSalle Station Design Heat Load of 722,217 BTU/hr giving a 29.9% thermal margin (Ref. 1, Table 10).Thermal margin is calculated by the following method: Required Heat Load -Calculated Heat Transfer = Thermal Margin[Equation 1]To express this as a percent of the required heat load, the following method is used: ThermaL argm inx 100% = %ThermalMargin Re quiredHeatLoad

[Equation 2]When the service water inlet temperature is increased to 104 0 F for the same limiting flow rate, but with a design fouling factor of 0.02650655 hr*ft2*OF/BTU, the heat transfer reduces to 874,052 BTU/hr which results in a 21% thermal margin over the design heat transfer rate of 722,217 BTU/hr [Attachment A]. Factoring in a 5% plugging allowance in the heat exchanger and running the model again at the design fouling factor and 104 0 F inlet service water temperature resulted in a 869,248 BTU/hr heat transfer rate, a 20.4% thermal margin above the design heat load[Attachment B]. Furthermore, the maximum fouling factor (at 104*F & 5% plugged) was found to be 0.005 hr*ft 2*OF/BTU tube-side and 0.0005 hr*ft 2*OF/BTU air-side (0.0888 hr*ft 2*OF/BTU overall)[Attachment C]. Additional conservatism explored the heat transfer effects with a 10% outlet airflow reduction, from 26,400 acfm to 23,760 acfm. This yielded a heat transfer rate of 814,593 BTU/hr (at design fouling conditions, 104 0 F, and 5% tube plugging allowance) resulting in a 12.8%thermal margin [Attachment D].I E-FORM.I CornEd NES-G-14.02 Effective Date: 04/14/00 CALCULATION PAGE ICALCULATION NO.97-199 REV.

SUMMARY

AND CONCLUSIONS The B & C RHR Pump Room Cooler Model was found to have adequate thermal margin for a maximum lake temperature of 104OF when operated at the design fouling condition.

The maximum fouling factor was found to be 0.005 hr*ft 2*OF/BTU tube-side and 0.0005 hr*ft 2*OF/BTU air-side (0.0888 hr*ft 2*OF/BTU overall) while maintaining the required heat transfer rate at 104 0 F inlet temperature and with a 5% plugging allowance.

Aboye JOB NO 31-003 CLIENT Commonwealth Edison PROJIE- LaSalle Station GL 89-13 Heat Exchanger Testing TITLE VY Cooler Thermal Performance Model -- 1(2)VY03A 1. PURPOSE The purpose of this calculation is to develop a thermal performance analysis model for the Commonwealth Edison (ComEd) LaSalle Station SE cubicle area coolers I (2)VY03A.

This model can be used for the analysis of heat exchanger thermal performance test data as part of the LaSalle Station GL 89-13 heat exchanger testing program or for any other engineering analysis subject to the limitations itemized at the end of this section.Once developed, the model is used to identify the thermal margin of the heat exchanger at specified performance conditions as follows: " at LaSalle Station Reference Conditions as currently defined in the LaSalle Station design and licensing basis; and" at lower service water flow rates (with increased fouling) to support service water system re-balancing efforts.The thermal performance model documented in this calculation has been created and used with PROTO-HX, Version 3.01. The model can be used with previous versions of PROTO-HX and produce identical results as long as the following restriction is upheld:* Air coils analyzed in Version 3.0 or earlier can be analyzed only in non-condensing modes of operation.

Current limitations of use for PROTO-HX are established by the limits on fluid properties included within the software.

Fluid properties contained within PROTO-HX are currently limited to the following temperature ranges:* Air: 32-320°F* Water: 32-5007F 2. BACKGROUND LaSalle Station is in the process of implementing a heat exchanger thermal performance monitoring program and a service water system flow balancing program in response to the requirements of NRC Generic Letter 89-13. Development of an analytical model in PROTO-HXTM, Version 3.01, will allow timely analysis of data resulting from the test program and will ensure the limiting flow requirements for the coolers are adequately defined.

DESIGN INPUTS The thermal performance model is developed using PROTO-HX T M , Version 3.01. PROTO-HX T M was developed and validated in accordance with Proto-Power's Nuclear Software Quality Assurance Program (SQAP). This program meets the requirements of 10CFR50 Appendix B, I OCFR2 1, and ANSI NQA- 1, and was developed in accordance with the guidelines and standards contained in ANSIIIEEE Standard 730/1984 and ANSI NQA-2b-1991.

PROTO-HXI T M Version 3.01 was verified and approved for use as documented in Reference (1).The design inputs for this calculation consist of the heat exchanger design basis performance requirements (Tablel), performance specifications (Table 2) and construction details (Table 3)provided by the heat exchanger manufacturer data sheet (Attachment A) or other design documents as referenced.

Construction details give the necessary information for model construction while performance specifications are used to benchmark the model.VY cooler thermal performance in this calculation will be. assessed only with respect to the nominal accident conditions (i.e., design basis LOCA) with no tubes plugged. Condensing modes of operation and tube plugging margins are not addressed.

Aboye JO0 NO 31-003 CLIENT Commonwealth Edison r'ROJEcT LaSalle Station GL 89-13 Heat Exchanger Testing TITLE VY Cooler Thermal Performance Model -- 1(2)VY03A 4. APPROACH This calculation utilizes plant/vendor fabrication specifications provided in Section 3.0 to develop a thermal performance prediction model for the 1(2)VY03A cooler. The calculation then benchmarks the model by comparing the heat transfer rate calculated by PROTO-HXTM Version 3.01 with the manufacturer's specifications for thermal performance.

The Colburn j-factor vs. Reynolds Number relationship is adjusted as necessary to meet the manufacturer's performance specifications.

After the model is benchmarked, it will be used to determine the margin between the available and required heat removal rates and to establish a revised limiting flow rate in support of service. water system re-balancing efforts.5. ASSUMPTIONS

1. The fouling factor specified in Reference (8) is for the tube-side only and design air-side fouling is zero. This is typical for air coils of this type and application.

Future validation of this assumption is not required.2. The slope of the "Colburn j-factor vs. Reynolds Number" curve is the same for the current coil and the standard coil represented by curve "CF-9.05-3/4 J-A" in the PROTO-HXTM "h-configurations" Library. This assumption is based on physical similarities between the VY coolers and the standard configuration represented by "CF-9.05-3/4 J-A" as elaborated in Section 6, below. The model benchmarking process described in Section 6 brings the model into precise agreement with the vendor performance data making initial configuration selection immaterial.

The only difference caused by initial configuration selection that would be detectable in analysis results is when analyses are performed over a very wide range (orders of magnitude) of air-side Reynolds numbers. A wide range of Reynolds numbers causes the slight variation in slopes of the j-factor equations of different configurations to become more obvious. Given the fixed fan flow rate and a relatively tight band of normal operating and Reference conditions, along with the fact that benchmarking conditions are extremely close to Reference conditions, such wide variations in Reynolds numbers are not anticipated.

Future validation of this assumption is not required.3. The vendor-supplied performance specifications of Reference (7) (included as Attachment A) are considered to be an accurate reflection of the as-built performance of the cooler. Future validation of this assumption is not required.4. The VY cooler spiral fin geometry is closely approximated by the PROTO-HXTM circular fin configuration.

This is due to the relatively tight fin pitch configuration resulting in a PROTO-POWER CORPORATION CALC NO.97-199 REV A PAGE 6 OF 24 GROTON, CONNECTICUT ORIGINATOR L. Philpot DATE 7/7/98 VERIFIED BY M. Aboye JOB NO.31-003 CLIENT Commonwealth Edison PROJECT LaSalle Station GL 89-13 Heat Exchanger Testing TITLE VY Cooler Thermal Performance Model -- 1(2)VY03A negligible difference in fin/tube outside surface area. This assumption is supported in Attachment K. Future validation of this assumption is not required.5. In transitioning from the original vendor specified inlet air temperature of 150°F to the current licensing limit of 148°F, the inlet air vapor density is assumed to have remained unchanged.

This increases the inlet relative humidity causing a slight reduction in the air mass flow rate. Future validation of this assumption is not required.6. ANALYSIS 6.1 Tube Pitch The longitudinal (horizontal) tube pitch is not directly available from the coil data sheet or Reference (20). It can be estimated based on the geometry of the coil. Per Reference (7), the coil stack depth is 14.00 inches. Dividing the stack depth evenly between 10 tube rows yields a longitudinal (horizontal) tube pitch of 1.400 inches.6.2 Coil Configuration The coil configuration for modeling cooler 1(2)VY03A is selected based on the physical characteristics of the coil. There are no coils in the PROTO-HXTM library that exactly match the configuration of cooler 1(2)VY03A.

The configuration "CF-9.05-3/4 J-A" shown in Figure 1 provides the closest match based on similarities of layout geometry:

staggered tube rows, identical fin thickness, similar fin height and similar fin pitch. The "CF-9.05-3/4 J-A" configuration also represents a relatively compact coil which correlates well to the VY coils as evidenced in the coil photographs included as Attachment B.PROTO-HXTM does not include spiral fin configurations in the analytical methodology employed.

However, for the given fin pitch, the difference in calculated fin surface area between the VY cooler spiral fin configuration and the PROTO-HXTM1 circular fin configuration is negligible.

The negligible difference is illustrated further in Attachment K using a simplified area comparison.

The SHR can be assigned any value between 0 and 1 and represents the fraction of the total specified (constant) heat load that is due to sensible cooling alone. An input of 1.0 in the SHR field tells PROTO-HXTM that the specified constant heat is 100% sensible heat with no condensation occurring.

Use of any value less than 1.0 presumes some knowledge as to what fraction of the specified heat load is due to condensation (i.e., latent heat transfer).

The value of SHR currently in the model is 1.0, but like any other model input, the SHR can be changed at any time.6.4 Derivation of Benchmarking Inputs The PROTO-HXTM model is benchmarked using the performance data provided by the cooler manufacturer.

In order to benchmark the model, the vendor specified conditions must be converted into appropriate units for PROTO-HXTM input. The only input requiring adjustment is the specified air-side flow rate of 25,420 scfm. PROTO-HXTM requires air-side flow rate to be given at actual inlet air conditions (units of acfin).

Per Reference (13), local atmospheric pressure was accounted for by specifying a flow at standard density (25,420 scfin) as well as an actual flow (26,400 acfmn at 70'F and 40% relative humidity at site elevation).

A significant impact on the model predicted performance is the outside (air-side) heat transfer coefficient.

The benchmarking process adjusts the model correlation for outside heat transfer coefficient to match vendor performance data.An extensive source of information pertaining to the outside heat transfer coefficient for air coolers is provided by Reference (15). This widely-recognized publication provides heat transfer correlations for specific coil configurations.

The format used in Reference (15), and subsequently adopted by other researchers, is to provide a plot of the Colbum j-factor vs. Reynolds Number for each configuration.

Alternatively, to permit modeling of coils which do not adequately fit the library configurations and for which no test data correlation is available, PROTO-HXTM allows the generation of a coil unique formulation for outside heat transfer coefficient.

This is done through establishing a unique Colburn j-factor for the coil.Reference (15) defines the Colburn j-factor as follows.Let: Cpa =Specific heat of air (Btu/Ibm-0 F)Thermal conductivity of air (Btulhr-ft-°F)

However, the heat transfer rate under design operating conditions using the standard configuration was slightly greater than the value specified by the manufacturer (see performance run in Attachment C). For this reason, a new curve relating the Colburn j-factor and Reynolds Number was generated according to the following procedure: " The slope of the linear standard curve was calculated." A new curve, parallel to the standard curve, was defined such that the new j-intercept is slightly lower.

This assumption is considered reasonable based on the following: " there are only minor variations in the slope of different j-factor correlations; and," there is only a slight variation in the air-side Reynolds Number between anticipated test conditions and the extrapolated accident conditions.

The only variation is expected to be caused by air inlet temperature variations (i.e., volumetric flow rate in cfm will be nearly constant, while air flow in acfm will vary with temperature and inlet humidity).

The inlet dry bulb temperature and pressure for the LaSalle Station Reference Conditions are listed in Table 1. The inlet relative humidity is adjusted by holding the vapor density constant from the vendor specified condition to the LaSalle Station Reference Condition (i.e., 148°F in lieu of 150'F).Given per Section 6.4 Vapor Density: 0.001248 lbm/ftA3 Reference Condition Dry Bulb Temperature:

12.76 %Since fans are constant volume equipment, the air volumetric flow rate of 26,400 cfm specified in References (18) and (19) remains the same for all coil outlet conditions.

The air mass flow rate through the coil, however, will vary with the temperature of the air going through the fan (i.e., at coil outlet temperature).

Deriving the inlet air flow rate for input to PROTO-HXTM requires an iterative solution as follows:* take an initial guess at the coil outlet air temperature at the same specific humidity as the coil inlet;* calculate the dry air density at the selected coil outlet air temperature;

• calculate the coil inlet air flow rate by multiplying the fan capacity (cfm) by the ratio of the coil outlet dry air density to the coil inlet dry air density (to maintain constant mass flow across the coil) [Equation (2)];* run the model with the inlet air flow rate derived above;* check the predicted coil outlet air temperature; and* repeat the process (substituting the predicted coil outlet air temperature for the initial guess)until the coil outlet air temperature does not change from one iteration to the next PROTO-POWER CORPORATION CALC NO.97-199 REV A PAGE 16 OF 24 GROTON, CONNECTICUT ORIGINATOR L.

The maximum available heat removal rate is calculated using the benchmarked PROTO-HXTM model and the inlet conditions defined in Section 6.7 with zero fouling. By comparing the available heat removal rate calculated with zero fouling (ce.~an) to the required heat removal rate, the maximum available margin is determined.

A similar comparison is made between the required heat load to the available heat load at design fouling conditions (qservice)"

Aboye JOB No 31-003 CLIENT Commonwealth Edison PRIoECT LaSalle Station GL 89-13 Heat Exchanger Testing TITLE VY Cooler Thermal Performance Model -- 1(2)VY03A For the purposes of this thermal margin assessment, thermal margin is defined as follows: Margin (BTU / hr) = q available

-q required Margin (%) q available q required x 100 q required Equation (10)Equation (11)where: qavailable

= the predicted heat capacity of the cooler at the specified conditions (BTU/hr)qrequired

= the heat capacity required of the cooler to fulfill design basis requirements (BTU/hr)6.9 Limiting Cooling Water Flow Analysis In support of the LaSalle Station efforts to re-balance the CSCS Equipment Cooling Water System, specification of a minimum acceptable cooling water flow to the VY coolers is desired.For conservatism, the design fouling factors associated with the limiting flow analysis are increased to 0.002 on both the tube and air sides of the cooler. Increasing the design fouling factors increases the fouling margin of the cooler at the reduced flow rates.Limiting flows are established by iterating with the performance model. The cooling water flow rate is incrementally reduced with each iteration until the target thermal margin of approximately 30% with the increased design fouling factors is achieved.6.10 Impact of Missing Fins Reference (3) identified the fact that two of the tubes in the front row of 1VY03A are missing fins for a tube length of 5.25 inches leaving an adjusted finned tube length of 102.75 inches.This reduces the heat transfer surface area for the first row. To assess the impact of this configuration, an additional iteration is made with the model. Since PROTO-HXTM does not allow the specification of different lengths by tube row, a comparison of the thermal performance capability of a coil with proper finned length to that of a coil with the adjusted finned length is required.

This is done by running the model with a revised value for coil finned length. The results of the PROTO-HXTM analysis of this configuration is then compared to the results with the effective coil finned length defined in Section 6.6. By focusing only on the heat transfer results tabulated for the first row, a difference in thermal performance attributable to the shorter PROTO-POWER CORPORATION CALC NO.97-199 REV A PAGE 18 OF 24 GROTON, CONNECTICUT ORIGINATOR L.

By pro-rating the differences identified to account for the fact that only 2 of the 24 tubes in the first row are affected, an estimation of the net effect is obtained.6.11 Fouling Sensitivity Analysis To assess the sensitivity of the 1(2)VY03A coolers to tube-side fouling accumulations, a series of iterations are performed.

With each iteration, the design tube-side fouling factor is incrementally increased from a value of 0.0000 to 0.0040 while the air-side fouling factor is held constant at the revised level of 0.002. The heat removal capability resulting from each fouling increment is compared to the required heat load to assess the thermal margin. Thermal margin is calculated using Equations (10) and (11).7. RESULTS 7.1 Model Benchmarking The first model case was based on the standard CF-9.05-3/4 J-A configuration available from the PROTO-HX T M library. The results of this initial benchmarking case are presented in Table 5.The PROTO-HXTM reports associated with the initial benchmark case are included as Attachment C.Table 5: Initial Benchmark Case -Standard CF-9.05-3/4 J-A Configuration Design q(1 1 PROTO-HX T M Percent Cooler (BTU/hr) Predicted q (BTU/hr) Difference 1(2)VY03A 1,108,000 1,157,626

The PROTO-HXTM reports associated with the fouling sensitivity analysis and a graphical presentation of the results are included as Attachment M. It should be noted that neither the Table below or the figure in Attachment M have taken analytical uncertainty into account since the intent of this exercise is to assess the change in thermal margin (i.e., the slope of the curves in Attachment M). Analytical uncertainty treated as a bias on the results will have a negligible effect on the slope of the curves.Consideration of uncertainty would, however, change the point at which a thermal margin of 0%is reached.

CONCLUSIONS A model for the LaSalle County Station Units I & 2 SE Cubicle Area Coolers was developed using PROTO-HX T M Version 3.01. The model was benchmarked and validated using the performance specifications provided by the cooler vendor. The close correlation with vendor specified and model predicted thermal performance confirms that the models are to be considered acceptable for use in the GL 89-13 heat exchanger testing program and related performance analyses.The available thermal margin for the coolers has been defined for the nameplate rated flow of 180 gpm and for a reduced flow rate of 72.5 gpm in support of service water system re-balancing efforts. Inclusion of a conservative assessment of the uncertainty in the analytical methods of PROTO-HXTM has provided high confidence in the thermal margins defined by the model for all cases.The model database is saved under file name vy-03a.phx, with a file size of 1,277,952 bytes, and a file date and time of 7/6/98 at 6:21:52 pm. The saved database is set up to run the 72.5 gpm case with adjusted design fouling factors of 0.002 air-side and 0.002 tube-side.

System classifications are as shown in Section 3.2. All portions of this system are protected from the effects of tornados, missiles, pipe whip, and flooding.c. To meet single failure criteria, the CSCS-ECWS for each unit is designed as three independent subsystems, one of which is shared between units (Drawing Nos. M-87 and M-134).d. Strainers are provided to prevent plugging of cooled component heat transfer passages.

All strainers include provisions for backwashing without significantly affecting system operation.

Organic fouling of heat transfer surfaces will be minimized by the chemical feed system which will treat the service water tunnel inlet flow-with oxidizing biocides.

However, the chemical feed system should not be considered auxiliary equipment required for the CSCS-ECW systems to perform their function.

Therefore, the operability of the-CSCS-ECW systems should not be tied to the operability of the chemical feed system. Connections and isolation valves are also provided immediately upstream and downstream of each cooled component for injection and circulation of biocidal agents, if necessary.

e. To detect leakage of radioactivity to the environment, radiation monitors are installed in the CSCS-ECWS immediately downstream of cooled components that contain radioactive fluids. The CSCS-ECWS discharge lines from these components are capable of remote manual isolation from the main control room.f. Design of system piping and components is based on a 40-year life.Exterior surfaces of all buried system piping is protected by bituminous coatings and wrappings and provisions for cathodic protection are installed where such protection is found to be required based on electrical potential measurements.

The design of all system piping includes a corrosion allowance of at least 0.08 inches.Proto-Power Caic: 97-199

[Circular Fin Air Coil Application]

Purpose The purpose of the following calculation is to evaluate the analytical uncertainty associated with the analysis of test data and the computation of heat transfer rate at a given extrapolation condition.

This calculation focuses only on the parameters that are not measured during the thermal performance test but factor into the analysis of the test results. Test parameter measurement uncertainty is treated separately in the test uncertainty analysis.

The calculation of analytical uncertainty is derived for a typical Air Cooler with "n" tube rows.Governing Heat Transfer Equations Heat transfer calculations associated with a heat exchanger generally reduce to satisfying the following equations:

I) q = U AO LMTD Where: q = Heat transfer rate at test conditions (BTU/hr)U = Overall heat transfer coefficient at test conditions (BTU/hr-°F-ft

)Ao = Heat transfer surface area referenced to outside (air-side) surface (ft 2)LMTD = Log Mean Temperature Difference at test.conditions (IF)and'2) q = rhcp (T,,. -Ta) = pQcp AT Where: q = Heat transfer rate at test conditions (BTU/hr)rin = Mass flow rate at test conditions (lbm/hr)CP = Specific heat of cooling water at test conditions (Btu/Ilbm-F)= Tube-side inlet temperature at test conditions

(°F)Too = Tube-side outlet temperature at test conditions (OF)p = Density of tube-side fluid at average bulk temperature at test conditions (lb/f1 3)Q = Volumetric flow rate of tube-side fluid at test conditions (gpm)The first equation is used, in Proto-HX, to evaluate the heat transfer rate from test data. The analytical uncertainties associated with evaluating the fluid properties are usually the only contributors to the overall uncertainty when using this equation.

For a given test condition, the right hand side of the second equation is evaluated such that it matches the measured heat Proto-Power Calc: 97-199

Accordingly, the change in the value of D (i.e., AD) due to changes in each of the independent variables (AA, AB, AC) may be represented by the following equation: AD -DAA + -DAB + DAC 0 A cB dC If AA, AB, AC are the known (or estimated) errors of the independent variables, then the error, AD, associated with the derived value, D, is calculated.

[I]. It is assumed that all independent variables in each equation have no influence on each other. For example, in Equation (6), LMTD* and the overall heat transfer coefficient, U*, are independent of each other. More specific assumptions are stated in each section as applicable.

For the rating analysis case (i.e., fouling factor is specified and not calculated from test data), equations 2, 3 and 4 above are not applicable because the uncertainty in the specified fouling factor is zero. The analytical uncertainty calculation, therefore, is reduced to an accounting of area uncertainty from equation 1 and the uncertainty in extrapolation terms per equations 5 and 6.Proto-Power Calc: 97-199

K Rev: A Page 1 of 4 COMPARING SPIRAL AND CIRCULAR FINS Area Calculation A view of the spiral fin layout as compared to the circular fin layout is provided below.Let angle ct represent the angle between the plane of the circular fin and the plane of the spiral fin.* F~.Is.~nI C.~,i Ffl (tJL~d8~A differential area in the circular fin is given as: dA = rdrdO The expression for circular fin surface area (times 2 for both sides and disregarding the edge area) taken over a complete traverse of the tube is given as: ACf = 2 rdrd0 = 2)r(r.2 -r i)Where: r. = the fin outside radius which is one half the fin height ri = the inside fin radius which is the tube outside radius Proto-Power Calc: 97-199

K Rev: A Page 2 of 4 The spiral fin surface area (times 2 for both sides and disregarding the edge area) can be approximated by the expression:

A~r (-- --1 2ff(ro2- rif)The ratio of the two areas becomes: Act Ac = cosa Angle cc is approximated by the expression:

1-(fin separation) 1 tan a 4 r. 4r./, a = tan-'(1 where: X =fin pitch Substituting fin height into the expression yields the following:

a = tan-' 2 tan-' 1 As the angle a goes to zero, the spiral fin area approaches that of the circular fin. It can be seen that for very small fin separations (i.e., high fin pitch) the smaller the resulting angle a.For the case of the VY cooler fin geometry: a = tan- .48-)(1 = tan-' (0.033625)

K Rev: A Page 3 of 4 The resulting area ratio is then: Af cos(1.93 1.00057 This difference' is negligible and is bounded by the uncertainty in the analysis presented in Attachment J.Heat Transfer Coefficient The fin geometry affects the calculation of the outside heat transfer film coefficient (ho)for condensing modes of operation.

Vertical (circular) fins provide for better condensation heat transfer since the condensate falls away from the fins at a faster rate than if the fin were inclined (i.e., spiral geometry).

As shown in the area discussion above, the angular difference between the circular fin geometry and the spriral fin geometry for the VY coils with a fin pitch of 10 fins per inch is very small (i.e., <20).The angle of incline, therefore, is deemed to be sufficiently small as to make the difference between circular and spiral fin geometries negligible even for condensing modes of operation.

In other words, as far as condensation removal from the fin surfaces is concerned, the 10 fin per inch fin pitch of the VY coils results in a fin orientation that is sufficiently close to vertical as to make differences in condensation heat transfer predictions negligible.

.I The purpose of this revision is to pertbrm sensitivity computer calculations for the subject air cooler using reduced air inlet flow rates. This information may be used in the future for assessments of system performance in cases where air flow through this cooler may be slightly below the intended design values. Cases involving a 5% reduction and 10% reduction in inlet air volumetric flow will be calculated so that effect on heat transfer rate (Btulhr) can be assessed.

The existing computer model for the air cooling coil I (2)VY03A generated in Revision A of this calculation will be used for this revision.2.0 METHODOLOGY AND ACCEPTANCE CRITERIA 2.1 The methodology for this calculation involves the following activities:

• Utilize approved Proto-F1x software.

I (2)VY03A cooling coil model (generated in Revision A of this calculation), to calculate the heat exchanger performance with reductions in inlet air volumetric flow of 5% and 10% (two cases).2.2 The acceptance criteria for this calculation is the following:

• There is no specific acceptance criteria as the purpose of this calculation is merely to predict additional data points for heat rejection capability based on reduced air inlet flow values.3.0 ASSUMPTIONS 3.1 There are no assumptions within this calculation.

B 7 Project NO: =PAGE NO./ATTACHMENT P 6.0 CALCULATIONS The existing Proto-Hx Model for this cooling coil. has adjusted design fouling factors of. Air Side=O.002 and Tube Side=O.002.

this is acceptable and conservative for use in this sensitivity study.since the design values for these parameters are Air Side-=0 and Tube Side=0.00l15 (per Table 2 of this calculation).

The cooling water flow rate used is 72.5 gpm, which is a limiting value, per Section 7.3 of this calculation.

Additional computer runs were made to evaluate cases of reduced air flow entering the cooler as follows: a) Benchmark case (Run No. 1) using the above indicated fouling factors and the tube side flow rate=72.5 gpm. Air flow into the cooler is 28,070 aclin (identical to fouling sensitivity case in Attachment M). The other input extrapolation data, e.g. tube inlet temperature, air inlet temperature, relative humidity, and atmospheric pressure are not altered. This computer run yielded identical results to the referenced Attachment M case indicating the model is working acceptably.

Since the VY fan is on the discharge side of the cooling coil, it is desirable to calculate the volumetric air flow on the discharge side of the coil. This is done by taking the exiting air-side mass flow given by Proto-Hx (from Row 10 of the coil), using the outlet density given by Proto-Fix convert to a volumetric flow (acfm).103.728 (ibm/hr) / 0.0655 (lbm/ft')

x 60 (min./hr)

= 26.394 acfm. say 26.400 acfm b) 5% reduction in inlet air flow (Run No. 2): Inlet air flow = 28.070 acfrn -5% = 26.666 acfm.This is the only input value changed for this case. The coil outlet flow is calculated as follows: 98,540 (lbm/hr) / 0.0656 (lbm/ft3) x 60 (min./hr)

= 25,036 acfm. say 25.000 acfm c) 10% reduction in inlet air flow (Run No. 3): Inlet air flow = 28,070 acfm -10% = 25.263 acfm. This is the only input value changed for this case.93.355 (lbm/hr) / 0.0657 (Ibm/ftl) x 60 (min./hr)

SUMMARY

AND CONCLUSIONS Following is a summary of the results based on the input inlet air flow values showing the predicted heat rejection:

Air Flow Reduction Inlet Air Flow base 28.070 acfm 5% 26.666 acfm 10% 25.263 acfm Outlet Air Flow 26,400 acfm 25,000 acfm 23.700 acfm Total [feat rransferred 938.124 Btuihr 909.799 Btu/hr 878.267 Btu/hr Based on Table I of this calculation, the required heat transfer rate for this cooler is 722.217 Btu/hr.As expected, the reduction in air inlet flow reduces the amount of heat transfer, however the calculated values are still well above the required heat transfer rate noted.

There are no assumptions for this revision.Inputs:* Cooling water temperature

= 107 OF (Reference 2)* Air temperature

= 148 OF (Reference 1)* Water flow rate = 66.5 gpm (39.2 gpm front, 27.3 gpm back) (Reference 1)* Air Flow rate = 27,075 cfm (Reference 1)* Fouling factor = 0.02228812 hr-ft 2.F/BTU (design fouling factor) (Reference 1)* 1 tube plugged (5% tube plugging) (Reference 1)

References:

1. Design analysis97-198, Rev. A, up to and including Revs AO0 through A02 2. EC 388666, Rev. 000 Identification of Computer Programs: The computer program used in this analysis is Proto HX version 4.01. This program has been validated per DTSQA tracking number EX0000103.

Method of Analysis / Numeric Analysis: The existing heat exchanger model will be revised by changing the input of the 'Tube Inlet Temp" from 104 OF to 107 OF. Because the 1(2)VY04A model consists of two separate models of the front and back portions of the cooler, the temperature, and relative humidity of the air exiting the front cooler are the inputs for the back cooler.The air flow rate is adjusted to match the mass flow rates between the two models. Because the fan for the coolers is at the exit of the cooler, the inlet air flow for the front cooler is iterated until the flow rate at the exit of the last row of the back cooler is approximately 27,075 cfm. The iteration process is detailed in section 6.7 of revision AOO. The calculated input flows for the two coolers are shown on the last page of Attachment A.Results I

Conclusions:

The 1(2)VY04A coolers can remove the design heat load of 633,288 BTU/hr with the following conditions:

• 107 OF cooling water temperature

• 148 °F air temperature

• design fouling factor of 0.02228812 hr-ft 2-°F/BTU* 1 tube plugged* air flow rate of 27,075 cfm 0 water flow rate of 66.5 gpm (39.2 gpm front, 27.3 gpm back)The total heat removed at these conditions is 697,494 BTU/hr, which provides 10.13% thermal margin over the design heat load. This thermal margin is enough to account for the 9.5% model uncertainty shown in Attachment J and is acceptable.

Note that a maximum fouling factor was not calculated as was done in previous revisions because it is not practical to set up test conditions that would allow accurate measurement of the fouling factor for these heat exchangers.

The bounding fouling factor is the design fouling factor of 0.02228812 hr-ft 2.°F/BTU.This case is shown in Attachment A.Attachments:

This assessment will evaluate the adequacy of these heat exchangers with a maximum allowable inlet service water temperature of 104'F, using the design fouling factor of 0.02228812, and 5% tube plugging.

Another case will be run to find the maximum fouling factor with the 5% reduction in air flow and 5% of the tubes plugged.Inputs: The design inputs consist of Reference 1 listed below.Assumptions:

The assumptions indicated in section 5.0 of Reference I are still valid.

References:

1. Calculation No.97-198, Rev. A, "Thermal Model of COMED / LaSalle Station Unit I and 2 LPCS Pump Room Coolers." Identification of Computer Programs: Proto Hx version 4.01 is used for this minor revision.

The same software was used for the other revisions in this calculation.

Method of Analysis and Acceptance Criteria: The existing heat exchanger model will be revised by changing the input of the air inlet flow rate, but the air flow rate is measured on the discharge of the cooler. Therefore, the 5% reduction is calculated on the exit of the cooler by manipulation of the inlet air flow rate. This reduction in flow along with the 5% plugged tubes, design fouling factor, and 104'F incoming cooling water was used to determine the thermal margin of the coolers and the maximum fouling factor. The acceptance criteria will be for the calculated heat transfer to exceed the LaSalle design heat load of 633,288 BTU/hr for 1(2)VY04A coolers (See Reference 1, Table 1). The original benchmark model developed for these heat exchangers demonstrated a correlation to vendor performance specification within an assumed 5% margin.Analysis: All input parameters except for air flow rate have remained the same and will not change for this model. Proto HX requires the inlet air flow rate, but our flow device is located on the exit of the heat exchanger.

Each of the coolers actually has two coolers in one (a front and back cooler). Therefore this revision will drop the front cooler air flow by 5%and the back cooler will take the exit flow rate of the front decreased from cooling of the air as its inlet flow. This translates to more than a 5% reduction in overall exit flow and therefore is conservative.

The current analyzed exit flow rate is taken from the 4 th row of the front cooler (see Reference I Rev AOO Attachment B, page B6), which is 108,332.51 Ibm/hr. Dividing this mass flow rate by the density (which is also on that same page) and converting to minutes gives an exit flow rate of 28,479 CFM. Reducing this number by x, 5% results in an exit flow rate of 27,058 CFM. Manipulation of the inlet flow rate was used until the exit flow rate is 27,058 CFM. Using this value for the inlet to the back cooler results in an exit flow rate of 26,520 CFM. Therefore the total reduction in air is 6.9%, which is more than 5%.When the Service Water inlet temperature is 1047F for the limiting flow rate of 39.20 gpm, a design fouling factor of 0.02228812 hr*fi 2*°F/BTU, and a 5% tube plugging allowance, the new total heat transfer is 450,396 BTU/hr for the front cooler and 290,765 BTU/hr for the back cooler for a total of 741,161 BTU/hr. The thermal margin is calculated as Qcalculated

-Qrequired, which is 741,161 -633,288 BTU/hr = 107,873 or 17.0 % gross Thermal Margin. Allowing for 5% model uncertainty, the net margin is 741,161(0.95)

-633,288 = 70,815 or 11.2% Thermal Margin.The maximum fouling factor with the same assumptions as above and a 5% model uncertainty is 0.07479374 hr*ft 2 l*F/BTU.Results /

Conclusion:

The l(2)VY04A coolers were found to have adequate thermal margin for a maximum lake temperature of 104'F when operated at design fouling conditions (0.02228812 hr*ft 2*OF/BTU), a 5% tube plugging allowance, and a 5% reduction in air flow rate. The maximum fouling factor is 0.07479374 hr*ft 2*°F/BTU. A reduced airflow rate of 27,075 ACFM (95% of 28,500) may therefore be used as acceptance criteria for airside flow rate testing (e.g. LTS-200-19).

AOO PAGE NO. 4 of 6 1.0 PURPOSE/OBJECTIVE The purpose of this minor revision is to revise the thermal model of the LPCS Pump Room Coolers (1VY04A, 2VY04A) for a 104 0 F Service Water inlet temperature.

This assessment will evaluate the adequacy of these heat exchangers during a maximum allowable inlet service water temperature of 104 0 F. Also an acceptable maximum design fouling factor will be determined.

2.0 METHODOLOGY AND ACCEPTANCE CRITERIA The existing heat exchanger model will be revised by changing the input of the "Tube Inlet Temp." from 100OF to 104OF and simulated for the following conditions:

design fouling factor and design fouling factor with 5% of the tubes plugged. The acceptance criteria will be for the thermal margin at each stated condition to exceed the LaSalle design heat load of 633,288 BTU/hr (Ref.1, Table 1). Additional conservatism was built into this acceptance criteria by assuming a 5% uncertainty in the Proto-HX heat transfer calculations.

The original benchmark model developed for this heat exchanger demonstrated a correlation to vendor performance specification well within this assumed 5% margin.A final case will be evaluated which determines the maximum acceptable fouling factor at which the design heat load can be accommodated including heat transfer model uncertainty and a 5%tube plugging allowance.

3.0 ASSUMPTIONS I ENGINEERING JUDGMENTS The assumptions indicated in section 5.0 of Reference 1 are still valid.4.0 DESIGN INPUTS The design inputs consist of References 1 listed below.

E-FORM I1 CornEd NES-G-14.02 Effective Date: 04/14/00 CALCULATION PAGE ICALCULATION NO.97-198 REV. NO. AOO PAGE NO. 5 of 6 6.0 CALCULATIONS The current calculation model is based on a Service Water inlet temperature of 1 00°F with varying cooling water flow rates. Based on Reference 1 Calculations, the limiting flow rate for this unit is 66.5 gpm. At this flow rate, temperature and at an assumed overall fouling factor of 0.03171750 hr*fe*OF/BTU, the amount of heat transferred is 818,271 BTU/hr compared with a LaSalle Station Design Heat Load of 633,288 BTU/hr giving a 29.2% thermal margin (Ref. 1, Table 10).Thermal margin is calculated by the following method: Required Heat Load -Calculated Heat Transfer = Thermal Margin[Equation 1]To express this as a percent of the required heat load, the following method is used: ThermalVf arginf_ x 100% = %Thermalk arg in Re quiredieatLoad

[Equation 2]When the service water inlet temperature is increased to 104OF for the same limiting flow rate, but with a design fouling factor of 0.02228812 hr*ft2*OF/BTU, the heat transfer reduces to 759,971 BTU/hr which represents a 20% thermal margin over the required heat transfer of 633,288 BTU/hr[Attachment A]. With a plugging allowance of 5% of the total tubes in the heat exchanger and running the model again at the design fouling factor and 104OF inlet temperature resulted in a 758,635 BTU/hr heat transfer, a 19.8% thermal margin above the design heat load [Attachment B].The maximum fouling factor (at 104 0 F & 5% plugged) was found to be 0.005 hr*f*°F/BTU tube-side and 0.0005 hr*fte*OF/BTU air-side (0.07479374 hr*ft 2*OF/BTU overall) [Attachment C].I E-FORM I CornEd NES-G-14.02 Effective Date: 04/14/00 CALCULATION PAGE ICALCULATION NO.97-198 REV.

SUMMARY

AND CONCLUSIONS The LPCS Pump Room Cooler Model was found to have adequate thermal margin for a maximum lake temperature of 104OF when operated at design fouling conditions.

The maximum fouling factor was found to be 0.005 hr*ft 2*OF/BTU tube-side and 0.0005 hr*ft 2*OF/BTU air-side (0.07479374 hr*ff 2*OF/BTU overall) while maintaining the required heat transfer rate at 104 0 F inlet temperature and with a 5% plugging allowance.

This model can be used for the analysis of heat exchanger thermal performance test data as part of the LaSalle Station GL 89-13 heat exchanger testing program or for any other engineering analysis subject to the limitations itemized at the end of this section.Once developed, the model is used to identify the thermal margin of the heat exchanger at specified performance conditions as follows: " at LaSalle Station Reference Conditions as currently defined in the LaSalle Station design and licensing basis; and* at lower service water flow rates (with increased fouling) to support service water system re-balancing efforts.The thermal performance model documented in this calculation has been created and used with PROTO-HX, Version 3.01. The model can be used with previous versions of PROTO-HX and produce identical results as long as the following restriction is upheld:* Air coils analyzed in Version 3.0 or earlier can be analyzed only in non-condensing modes of operation.

Current limitations of use for PROTO-HX are established by the limits on fluid properties included within the software.

Fluid properties contained within PROTO-HX are currently limited to the following temperature ranges: " Air: 32-320°F* Water: 32-500°F 2. BACKGROUND LaSalle Station is in the process of implementing a heat exchanger thermal performance monitoring program and a service water system flow balancing program in response to the requirements of NRC Generic Letter 89-13. Development of an analytical model in PROTO-HXTM, Version 3.01, will allow timely analysis of data resulting from the test program and will ensure the limiting flow requirements for the coolers are adequately defined.

Aboye Jo03 NO 31-003 CLIENT Conmmonwealth Edison PROJECT LaSalle Station GL 89-13 Heat Exchanger Testing TITLE VY Cooler Thermal Performance Model -- 1(2)VY04A 3. DESIGN INPUTS The thermal performance model is developed using PROTO-HX T M , Version 3.01. PROTO-HX T M was developed and validated in accordance with Proto-Power's Nuclear Software Quality Assurance Program (SQAP). This program meets the requirements of I OCFR50 Appendix B, IOCFR21, and ANSI NQA-1, and was developed in accordance with the guidelines and standards contained in ANSI/IEEE Standard 730/1984 and ANSI NQA-2b-1991.

PROTO-HX T M Version 3.01 was verified and approved for use as documented in Reference (1).The design inputs for this calculation consist of the heat exchanger design basis performance requirements (Tablel), performance specifications (Table 2) and construction details (Table 3)provided by the heat exchanger manufacturer data sheet (Attachment A) or other design documents as referenced.

Construction details give the necessary information for model construction while performance specifications are used to benchmark the model.VY cooler thermal performance in this calculation will be assessed only with respect to the nominal accident conditions (i.e., design basis LOCA) with no tubes plugged. Condensing modes of operation and tube plugging margins are not addressed.

Since the 1(2)VY04A cooler is made up of two separate and unique coil sections (a 4-row front coil and an 8-row back coil), two separate models will be developed.

Aboye JOB NO 31-003 CLIENT Commonwealth Edison PRo1ECT LaSalle Station GL 89-13 Heat Exchanger Testing TILE VY Cooler Thermal Performance Model -- 1(2)VY04A 4. APPROACH This calculation utilizes plant/vendor fabrication specifications provided in Section 3.0 to develop a thermal performance prediction model for the 1(2)VY04A coolers. The calculation then benchmarks the model by comparing the heat transfer rate calculated by PROTO-HXTM Version 3.01 with the manufacturer's specifications for thermal performance.

The Colburnj-factor vs. Reynolds Number relationship is adjusted as necessary to meet the manufacturer's performance specifications.

After the model is benchmarked, it will be used to determine the margin between the available and required heat removal rates and to establish a revised limiting flow rate in support of service water system re-balancing efforts.5. ASSUMPTIONS

1. The fouling factor specified in Reference (8) is for the tube-side only and design air-side fouling is zero. This is typical for air coils of this type and application.

Future validation of this assumption is not required.2. The vendor-supplied performance specifications of Reference (7) (included as Attachment A) are considered to be an accurate reflection of the as-built performance of the VY Cooler. Future validation of this assumption is not required.3. The slope of the "Colburn j-factor vs. Reynolds Number" curve is the same for the current coil and the standard coil represented by curve "CF-9.05-3/4 J-A" in the PROTO-HXTM "h-configurations" Library. This assumption is based on physical similarities between the VY coolers and the standard configuration represented by "CF-9.05-3/4 J-A" as elaborated in Section 6, below. The model benchmarking process described in Section 6 brings the model into precise agreement with the vendor performance data making initial configuration selection immaterial.

The only difference caused by initial configuration selection that would be detectable in analysis results is when analyses are performed over a very wide range (orders of magnitude) of air-side Reynolds numbers. A wide range of Reynolds numbers causes the slight variation in slopes of the j-factor equations of different configurations to become more obvious. Given the fixed fan flow rate and a relatively tight band of normal operating and Reference conditions, along with the fact that benchmarking conditions are extremely close to Reference conditions, such wide variations in Reynolds numbers are not anticipated.

Future validation of this assumption is not required.4. The portion of the total flow that is directed toward the front coil section will equally divide between the top and bottom coils since these coils are identical with no tubes PROTO-POWER CORPORATION CALCNO- 97-198 REV A PAGE 6 OF 30 GROTON, CONNECTICUT ORIGINATOR L.

The portion of the total flow that is directed toward the back coil section will equally divide between the top and bottom coils since these coils are identical with no tubes plugged. Future validation of this assumption is not required.5. The front and back coil sections have the same Colburn j-factor vs. Reynolds Number relationship.

This assumption is based on physical similarities between the VY coolers and the standard configuration represented by "CF-9.05-3/4 J-A" as elaborated in Assumption 3 above and Section 6, below. Future validation of this assumption is not required.6. The VY cooler spiral fin geometry is closely approximated by the PROTO-HX T M circular fin configuration.

This is due to the relatively tight fin pitch configuration resulting in a negligible difference in fin/tube outside surface area. This assumption is supported in Attachment K. Future validation of this assumption is not required.7. In transitioning from the original vendor specified inlet air temperature of 150'F to the current licensing limit of 148°F, the inlet air vapor density is assumed to have remained unchanged.

This increases the inlet relative humidity causing a slight reduction in the air mass flow rate. Future validation of this assumption is not required.6. ANALYSIS 6.1 Tube Pitch The transverse and longitudinal tube pitches are not directly available from the coil data sheet.They can be estimated based on the geometry of the coil. Per Reference (7), the coil stack depth is 8.00 inches for the front coil and 12.00 inches for the back coil. Dividing the stack depth evenly between 4 and 8 tube rows yields a longitudinal (horizontal) tube pitch of 2.00 and 1.500 inches for the front and back coils respectively.

6.2 Coil Configuration The coil configuration for modeling coolers 1 (2)VY04A is selected based on the physical characteristics of the coil. There are no coils in the PROTO-HXTM library that exactly match the configuration of the VY coolers. The configuration "CF-9.05-3/4 J-A" shown in Figure 1 provides the closest match based on similarities of layout geometry:

staggered tube rows, horizontal tube pitch slightly greater than vertical tube pitch, similar fin height, identical fin thickness and similar fin pitch. The "CF-9.05-3/4 J-A" configuration also represents a relatively PROTO-POWER CORPORATION CALC NO.97-198 REV A PAGE 7 OF 30 GROTON, CONNECTICUT ORIGINATOR L. Philpot DATE 7/13/98 VElIUFED BY M.

However, for the given fin pitch, the difference in calculated fin surface area and outside heat transfer film coefficient between the VY cooler spiral fin configuration and the ,PROTO-HXTM circular fin configuration is negligible.

The negligible difference is illustrated further in Attachment K using a simplified area comparison.

6.3 Sensible Heat Ratio The value input in the model for the Sensible Heat Ratio (SHR) is used only when one of the"Constant Heat Load" calculation/extrapolation methods of PROTO-HXTM is used (i.e.,"Constant Heat and Cold Inlet Temperature" or "Constant Heat and Hot Outlet Temperature").

The SHR can be assigned any value between 0 and I and represents the fraction of the total specified (constant) heat load that is due to sensible cooling alone. An input of 1.0 in the SHR field tells PROTO-HX T M that the specified constant heat is 100% sensible heat with no condensation occurring.

Use of any value less than 1.0 presumes some knowledge as to what fraction of the specified heat load is due to condensation (i.e., latent heat transfer).

The value of SHR currently in the model is 1.0, but like any other model input, the SHR can be changed at any time.

In order to benchmark the model, the vendor specified conditions must be converted into appropriate units for PROTO-HXTM input. The only input requiring adjustment is the specified air-side flow rate of 27,450 scfm. PROTO-HXTM requires air-side flow rate to be given at actual inlet air conditions (units of acfmn).The correction of scfm to acfm is made as follows (holding mass flow rate constant for the defining case): mh = (scfm) x(psi) x6OiJ (acfmi) x (p.ac,.) x 60 minh J Equation (1)where: rh = mass flow (lbm/hr)scfm = volumetric flow rate at standard conditions (ft 3/min)Pst = standard density of 0.075 Ibm/ft 3 acfm = volumetric flow rate at specified (non-standard) conditions (ft 3/min)Pactua = density of dry air at specified inlet temperature and humidity (lbm/ft 3)Rearranging terms yields the following correction factor for converting scfm to inlet acfm: (acfm) = (scfm) x (Ptd)Equation (2)Local Standard Atmospheric Pressure To derive the dry air density for the inlet air conditions, the amount of moisture in the air and the local atmospheric pressure must be accounted for. Per Reference (13), local atmospheric pressure was accounted for by specifying a flow at standard density (27,450 scfm) as well as an PROTO-POWER CORPORATION CALC NO.97-198 REV A PAGE 9 OF 30 GROTON, CONNECTICUT ORIGINATOR L.

The difference between the two flow rates will provide the assumed air density as follows: (pactuai)

Pressure input is varied with the specified temperature and humidity conditions held constant until a dry air density of 0.0722 Ibm/ft 3 is reached. The result of the iterative process is as follows: Given per Reference (13)Dry Bulb Temperature:

A plan view of this configuration is shown in Figure 2. Both the front and back coil sections have an equal number of open tube circuits'available to the incoming flow. The flow split between the coil sections, therefore, will be a function of the flow resistance of each coil with the majority of the flow going to the coil section that offers the least resistance to flow. By inspection, the majority of the incoming flow will go to the front coil due to the shorter length of tube and fewer tube bends. A quantitative derivation of the flow split is possible by accounting for the sources of flow resistance in each flow path.Given that the top and bottom and front and back coil sections are located in parallel, the total flow to the VY04A cooler splits four ways as follows: Qtotal = Qfront-top

A significant impact on the model predicted performance is the outside (air-side) heat transfer coefficient.

The benchmarking process adjusts the model correlation for outside heat transfer coefficient to match vendor performance data.An extensive source of information pertaining to the outside heat transfer coefficient for air coolers is provided by Reference (15). This widely-recognized publication provides heat transfer correlations for specific coil configurations.

The format used in Reference (15), and subsequently adopted by other researchers, is to provide a plot of the Colburnj-factor vs. Reynolds Number for each configuration.

Alternatively, to permit modeling of coils which do not adequately fit the library configurations and for which no test data correlation is available, PROTO-HXTM allows the generation of a coil unique formulation for outside heat transfer coefficient.

This is done through establishing a unique Colbumj-factor for the coil.

• A new curve, parallel to the standard curve, was defined such that the new i-intercept is slightly lower." A design performance run was then executed using the new Colbum j-factor versus Reynolds Number curve, and the resulting heat transfer rate was compared to the manufacturer's value.* The above two steps were repeated until the calculated heat transfer rate closely matched the manufacturer's value.Front and Back Coil Considerations The unique configuration of 1(2)VY04 coolers with front and back coils in parallel for cooling water flow and in series for air flow creates a benchmarking challenge in three ways: ,. The cooling water flow split is derived analytically as demonstrated above and, due to the lack of flow measurement capability, cannot be verified.* The vendor specified performance data does not distinguish between front and back coil sections with regard to total heat transferred by the coil combination or the predicted cooling water outlet temperatures (i.e., what fraction of the total heat load is carried by each coil section).* The vendor specified performance data does not include air-side inlet conditions for the back coil. Inlet conditions for the back coil section must be derived based on the performance of the front coil section.The result of the unique challenges of the I(2)VY04 cooler configuration is that the model benchmarking process becomes iterative in nature and must rely on an assumption of similarity of front and back coil section j-factor corrections

The combined heat transfer and cooling water outlet temperature are compared to that specified by the vendor.* Adjustments to both the front and back coil section are made and the process is repeated (the same Colburn j-factor adjustment made to both front and back coil sections).

• The process is repeated until a combined total heat transfer rate close to the specified heat transfer rate is achieved in conjunction with a combined cooling water outlet temperature close to the specified temperature.

The resulting relationship between Reynolds Number and Colburn j-Factor is represented by the following table and associated equation: Table 4: Reynolds Number and Colburn j-Factor Reynolds Number Colburn j-Factor (Standard)

The only variation is expected to be caused by air inlet temperature variations (i.e., volumetric flow rate in cfm will be nearly constant, while air flow in acfm will vary with temperature and inlet humidity).

An excerpt from Reference (15), illustrating the Colbum j-factor relationship with Reynolds number, is included as Attachment D.6.6 Derivation of Back Coil Benchmarking Inputs The inlet relative humidity and dry air density for the inlet to the back coil section are derived based on the outlet temperature and specific humidity of the front coil section. The equations of Reference (14) are used with the results included in Attachment H.The inlet air flow rate (acfmn) to the back coil is iterated with subsequent runs of the back coil model until a value is reached that maintains constant mass flow rate through both coil sections.6.7 Effective Coil Finned Length Reference (20) identified the fact that the finned coil length exposed to air flow was less than that specified by the coil vendor in Reference (7). Model benchmarking used the vendor specified length to be consistent with the vendor specified performance.

The effective length is entered into the model for all subsequent analysis.

An effective coil finned length of 105.00 inches is used per Reference (20).6.8 Extrapolation Conditions The LaSalle Station Reference Conditions defined in Table 1 are slightly different than the vendor specified performance conditions listed in Table 2 and require conversion to units for input into PROTO-HX T M.Air-Side Pressure Air-side pressure should account for the local elevation above sea level. Chapter 26, Table LA, of Reference (16) provides elevation and standard atmospheric pressure data for the local area around La Salle.

The air mass flow rate through the coil, however, will vary with the temperature of the air going through the fan (i.e., at coil outlet temperature).

Deriving the inlet air flow rate for input to PROTO-HXTM requires an iterative solution as follows: " take an initial guess at the coil outlet air temperature at the same specific humidity as the coil inlet;* calculate the dry air density at the selected coil outlet air temperature;" calculate the coil inlet air flow rate by multiplying the fan capacity (cfm) by the ratio of the coil outlet dry air density to the coil inlet dry air density (to maintain constant mass flow across the coil) [Equation (2)];* run the model with the inlet air flow rate derived above;* check the predicted coil outlet air temperature; and" repeat the process (substituting the predicted coil outlet air temperature for the initial guess)until the coil outlet air temperature does not change from one iteration to the next The iteration process described above was completed twice for this model for a clean (f-= 0.0)and service (f= design) condition with results as follows: Clean: (cflm.) =(cfmo°,) x (P..',) -(pin)(Pc.,x (cfmou, x x (pi")Service: (28,500) x (0.066368695)

Inlet air flow is calculated from Equation (1) initial estimates of back coil outlet temperature (fan temperature).

The back coil inlet air flow rate is derived to ensure the air mass flow rate through the back coil is the same as the air mass flow rate through front coil. The resulting back coil outlet temperature is then compared to the initial estimate.

An iterative process is used to ensure all flows are balanced accordingly.

Derivation of the necessary air properties is included in Attachment H.6.9 Thermal Margin Assessment The available thermal margin is defined as the difference between the available and the required heat removal rates at reference conditions.

The maximum available heat removal rate (qclean)is calculated using the benchmarked PROTO-HXTM model and the inlet conditions defined in Section 6.8 with zero fouling. By comparing the available heat removal rate calculated with zero fouling to the required heat removal rate, the maximum available margin is determined.

A similar comparison is made between the required heat load to the available heat load at design fouling conditions (q.service)" For the purposes of this thermal margin assessment, thermal margin is defined as follows: Margin (BTU / hr) = q available

Increasing the design fouling factors increases the fouling margin of the cooler at the reduced flow rates.Limiting flows are established by iterating with the performance model. The cooling water flow rate is incrementally reduced with each iteration until the target thermal margin is achieved.

For the case of 1(2)VY04A, the target thermal margin is approximately 30% with the increased design fouling factors.6.11 Fouling Sensitivity Analysis To assess the sensitivity of the 1(2)VY04A coolers to tube-side fouling accumulations, a series of iterations are performed.

With each iteration, the design tube-side fouling factor is incrementally increased from a value of 0.0000 to 0.0040. The heat removal capability resulting from each fouling increment is compared to the required heat load to assess the thermal margin.Thermal margin is calculated using Equations (10) and (11).7.

The results of the iterations to identify the limiting flow rate are summarized in Table 10. The PROTO-HX T M reports associated with the limiting flow analysis are included as Attachment I.Table 10: Limiting Cooling Water Flow Rate at Reference Conditions The uncertainty in the analytical methodology used to identify the limiting flow for 1(2)VY04A is presented in Attachment J. The result of the uncertainty assessment is that the uncertainty in the PROTO-HXTM extrapolated heat transfer rate ranges from +/- 5.81% to +/- 6.99% for the front coil and +/- 4.33% to +/- 6.36% for the back coil for the ranges of cooling water flow evaluated.

An uncertainty of+/- 7.00% and +/- 6.40% is used for the front and back coils respectively to conservatively bound the analysis of Attachment J. The combined analytical uncertainty for the two coils together is taken as the square root of the sum of the squares of the front and back coil contributions.

CONCLUSIONS Two models for the LaSalle County Station Units 1 & 2 NE Cubicle Area Coolers were developed using PROTO-HX T M Version 3.01. The models were benchmarked and validated using the performance specifications provided by the cooler vendor. The close correlation with vendor specified and model predicted thermal performance confirms that the models are to be considered acceptable for use in the GL 89-13 heat exchanger testing program and related performance analysis.The available thermal margin for the coolers has been defined for the nameplate rated flow of 200 gpm and for a reduced flow rate of 66.5 gpm in support of service water system flow requirements.

Inclusion of a conservative assessment of the uncertainty in the analytical methods of PROTO-HX T M has provided high confidence in the thermal margins defined by the model for all cases.The front coil model database is saved under file name vy-04a-f.phx, with a file size of 1,409,024 bytes, and a file date and time of 7/10/98 at 4:09:12 pm.

Strainers are provided to prevent plugging of cooled component heat transfer passages.

All strainers include provisions for backwashing without significantly affecting system operation.

Organic fouling of heat transfer surfaces will be minimized by the chemical feed system which will treat the service water tunnel inlet flow with oxidizing biocides.

However, the chemical feed system should not be considered auxiliary equipment required for the CSCS-ECW systems to perform their function.

Therefore, the operability of the CSCS-ECW systems should not be tied to the operability of the chemical feed system. Connections and isolation valves are also provided immediately upstream and downstream of each cooled component for injection and circulation of biocidal agents, if necessary.

e. To detect leakage of radioactivity to the environment, radiation monitors are installed in the CSCS-ECWS immediately downstream of cooled components that contain radioactive fluids. The CSCS-ECWS discharge lines from these components are capable of remote madual isolation from the main control room.f. Design of system piping and components is based on a 40-year life.Exterior surfaces of all buried system piping is protected by bituminous coatings and wrappings and provisions for cathodic protection are installed where such protection is found to be required based on electrical potential measurements.

Figures 2.4-4 and 9.2-1 illustrate the physical layout and area capacity of the ultimate heat sink.9.2.6.3 Safety Evaluation The station's ultimate water requirements (Units 1 and 2) in gpm are summarized below.*Proto-Power Calc: 97-198*Attachmnent:

[Circular Fin Air Coil Application]

Purpose The purpose of the following calculation is to evaluate the analytical uncertainty associated with the analysis of test data and the computation of heat transfer rate at a given extrapolation condition.

This calculation focuses only on the parameters that are not measured during the thermal performance test but factor into the analysis of the test results. Test parameter measurement uncertainty is treated separately in the test uncertainty analysis.

The calculation of analytical uncertainty is derived for a typical Air Cooler with "n" tube rows.Governing Heat Transfer Equations Heat transfer calculations associated with a heat exchanger generally reduce to satisfying the following equations:

1) q = U A 0 LMTD Where: q = Heat transfer rate at test conditions (BTU/hr)U = Overall heat transfer coefficient at test conditions (BTU/hr-*F-ft

)Ao = Heat transfer surface area referenced to outside (air-side) surface (ft 2)LMTD = Log Mean Temperature Difference at test conditions

(°F)and 2) q = riacp (To -T,,,) = pQcp AT Where: q = Heat transfer rate at test conditions (BTU/hr)ri = Mass flow rate at test conditions (lbm/hr)cp = Specific heat of cooling water at test conditions (Btu/lbm 0-F)TCi = Tube-side inlet temperature at test conditions (OF)TCo = Tube-side outlet temperature at test conditions (OF)p = Density of tube-side fluid at average bulk temperature at test conditions (lbm/ft 3)Q = Volumetric flow rate of tube-side fluid at test conditions (gpm)The first equation is used, in Proto-HX, to evaluate the heat transfer rate from test data. The analytical uncertainties associated with evaluating the fluid properties are usually the only contributors to the overall uncertainty when using this equation.

For a given test condition, the right hand side of the second equation is evaluated such that it matches the measured heat Proto-Power Calc: 97-198

The following equations are used for this iteration:

These same equations must be satisfied when evaluating the capacity of a heat exchanger at a given fouling condition (i.e., when extrapolating to the limiting thermal condition).

('F)Analytical Uncertainty Calculation Methodology The method for calculating the analytical uncertainty associated with this performance analysis method is illustrated as follows: Given a function D = f(A,B,C)The effect on D of slight changes in the independent variables A, B, and C may be calculated by taking the partial derivatives of D with respect to each of the independent variables.

Accordingly, the change in the value of D (i.e., AD) due to changes in each of the independent variables (AA, AB, AC) may be represented by the following equation: AD-AA+ -AB + AC cA dB 9C If AA, AB, AC are the known (or estimated) errors of the independent variables, then the error, AD, associated with the derived value, D, is calculated.

The most probable one standard deviation error representative of AD would be the statistical root mean squared value derived as follows: AD= [(-AA + + A = U-C 67A J 9 10C-Expressing the uncertainty in terms of a percentage of the value of D is simply a matter of including division by the value of D as follows: U, = [(,-D 2( AA) 2 + OD)'AB2 (OD 2AC 21/D cA K D) cB) B D) + -C) -D Proto-Power Calc: 97-198

J Rev: A Page 4 of 55 The next six sections of this document provide a step by step approach to calculating the analytical uncertainty associated with the six thermal performance equations outlined above.The specific terms to be evaluated from these equations are as follows: 1) Heat transfer area, A. and area uncertainty, U 4 2) Test condition heat transfer rate, q and heat transfer uncertainty, Uq 3) Test condition thermal resistance, R and thermal resistance uncertainty, UR 4) Observed overall fouling resistance, Rf fouling resistance uncertainty, URf 5) Extrapolation condition thermal resistance, R* and thermal resistance uncertainty, UR*6) Extrapolation condition heat transfer rate, q* and heat transfer rate uncertainty, Uq.All uncertainty equations used in this calculation are based on the methods of Reference

[ 1 ]. It is assumed that all independent variables in each equation have no influence on each other. For example, in Equation (6), LMTD* and the overall heat transfer coefficient, U*, are independent of each other. More specific assumptions are stated in each section as applicable.

For the rating analysis case (i.e., fouling factor is specified and not calculated from test data), equations 2, 3 and 4 above are not applicable because the uncertainty in the specified fouling factor is zero. The analytical uncertainty calculation, therefore, is reduced to an accounting of area uncertainty from equation 1 and the uncertainty in extrapolation terms per equations 5 and 6.Proto-Power Calc: 97-198

K Rev: A Page 1 of 4 COMPARING SPIRAL AND CIRCULAR FINS Area Calculation A view of the spiral fin layout as compared to the circular fin layout is provided below.Let angle cc represent the angle between the plane of the circular fin and the plane of the spiral fin.A differential area in the circular fin is given as: dA = rdrdO The expression for circular fin surface area (times 2 for both sides and disregarding the edge area) taken over a complete traverse of the tube is given as: ACf =2 ,rdrd0 = 2 r(ro -r 2)Where: r. = the fin outside radius which is one half the fin height ri = the inside fin radius which is the tube outside radius Proto-Power Calc: 97-198

Attachment:

K Rev: A Page 2 of 4 The spiral fin surface area (times 2 for both sides and disregarding the edge area) can be approximated by the expression:

A , 2,7a .i'Af ~cosa)2ra-r.The ratio of the two areas becomes: A,: = (cosaJ Acf Angle a is approximated by the expression:

-(fin separation) 1 tan a = 4 ro 4r 0 2 a = tan- -where: X = fin pitch Substituting fin height into the expression yields the following:

a = 2f ntan-' 1 As the angle cc goes to zero, the spiral fin area approaches that of the circular fin. It can be seen that for very small fin separations (i.e., high fin pitch) the smaller the resulting angle oa.For the case of the VY cooler fin geometry: a = = tan-'= tan-'(0.033625)

= 1.93-2H (2(l.487)(10))

Proto-Power Calc: 97-198

Attachment:

K Rev: A Page 3 of 4 The resulting area ratio is then: A,. cos(1.93) 1.00057 This difference is negligible and is bounded by the uncertainty in the analysis presented in Attachment J.Heat Transfer Coefficient The fin geometry affects the calculation of the outside heat transfer film coefficient (h,,)for condensing modes of operation.

Vertical (circular) fins provide for better condensation heat transfer since the condensate falls away from the fins at a faster rate than if the fin were inclined (i.e., spiral geometry).

As shown in the area discussion above, the angular difference between the circular fin geometry and the spriral fin geometry for the VY coils with a fin pitch of 10 fins per inch is very small (i.e., <20).The angle of incline, therefore, is deemed to be sufficiently small as to make the difference between circular and spiral fin geometries negligible even for condensing modes of operation.

In other words, as far as condensation removal from the fin surfaces is concerned, the 10 fin per inch fin pitch of the VY coils results in a fin orientation that is sufficiently close to vertical as to make differences in condensation heat transfer predictions negligible.

The Effective Finned Tube Length was taken with a metal tape measure. The uncertainities for these measurements are based on engineering best estimates for the measurement techiniques used and are as stated in NDIT LS-0835 dated 6/19/98. Each cooler appeared to have staggered rows of tubes. The transverse tube pitch was variable for the various individual fins and the above dimension is considered typical.Attachment"1 contains two sheets with sketches of the identical dimensions provided above.NDIT LS-0847, Page 2 of 2 end.
