These rooms are located on elevations 692.0 and 708.0 of the Control Building.

The calculation also evaluates the adequacy of the equipment/components associated with the EBR HVAC system.Standard ASHRAE methods were used in determining the loads and temperature I humidity conditions.

Results indicate that adequate chiller and AHU coil capacities exists to maintain acceptable environmental conditions within spaces served for all normal operational and worst case DBE conditions.

The calculation was updated on Revision 16 to address Unit 2 1 Dual Unit Operation.

An unverified assumption for Unit 2 only assumes this stage 3 of DCN 51656-A will be cancelled.

Stage 3 of DCN 51656-A is not cancelled as evident by Revision 18.Revision of the Appendix 11 analysis for Unit 2 / Dual Unit Operation was not changed in support of stage 3 of DCN 51656-A and PIC 52252-A.Revision 021 was initiated to provide humidity for the Unit 2 Auxiliary Instrument Room for the during LOCA condition.

Revision of the Appendix 11 analysis for Unit 2 Operation was not within the scope of Revision 021 and was not changed. Therefore; UVA was not removed.MICROFICHE/EFICHE Yes 0 No X FICHE NUMBER(S) 0 0 LOAD INTO EDMS AND DESTROY X LOAD INTO EDMS AND RETURN CALCULATION TO CALCULATION ADDRESS: EQB 1 M -WBN LIBRARY.0 LOAD INTO EDMS AND RETURN CALCULATION TO: TVA 053 [10200] Pae 1of INED-2-1[1 008 TVA 40532 [10-2008]Page 1 of 1 NEDP-2-1 [10-2D-20081 NPG CALCULATION COVERSHEETICCRIS UPDATE P age " CAIC ID I TYPE I flR(IPL ANT IBRANCH I NUMBER I REV I I PLANT I BRANCH 1 CN I NUC WBN MEB EPMMCP071689 I 021 ALTERNATE CALCULATION IDENTIFICATION, BLDG ROOM ELEV COORD/AZIM FIRM PrintReport Yes El 05 N/A I N/A N/A BECHTEL CATEGORIES NA KEY NOUNS (A-add, D-delete)ACTION KEY NOUN AID KEY NOUN (AID)CROSS-REFERENCES (A-add, C-change, D-delete)ACTION XREF XREF XREF XREF.

This Revision, Revision 8 Is as described below. I 1 4f Revision 8 of this calculation documents the Heat load analysis and establshes room temperature condition due to the replacement of Unit 1 Westinghouse Plant Process Computer with an integrated Computer System (ICS) in support of DCN M3991 1-A.The resultant room temperature changes (NORMAL /LOCA) in the Aux. Instrument Room 708- CI and Computer Room 708-C3 and Battery Board Room 692-C4 due to sensible load changes. There has been a descripancy found for Room 708-Cl maximum temperature in LOCA condition vs. the environmental drawing (47E235-17) and Environmnetal calculation WBNAPS4-004, The PER (CHPER980147) has been written for corrective action needed to revise environmental drawing and successor calculation.

The computer Room 708-C3 and Battery Board Room 692 -C4 temperatures have no impact on environmental drawings.

Also additional existing non-conservative methodology for certain rooms were found and corrected and resulted in no increase in NORMAL/ LOCA temperatures condition.

Thus these changes have no adverse affect on Electric Board rooms HVAC system.Pages Added: 2g (Revision log), 4e (IR Form).Pages Deleted: None Pages Changed: Ic, 5, 5a, 6,, 12, 13, 20, 21, 22, 23,28,29, 38, 39, 59, 60, 73, 74, 75, 76, 77, 78, 80. 81, 82, 83, 84, 93, 95, 96. -97, 98, 99,100,101,102 103, Appendix B pages 103 h, 103 1 and 103 j, This Revision log contains 4z. pages.Prepared by .date 12-i- Checked by date 12-.

Therefore, revision bars were not added.Revision 14 incorporated changes per DCN D51656A which lowered each AHU bypass damper controller setpoint to 68*F to decrease the environmental temperature limits in the spaces served by the Electrical Board Room (EBR) air conditioning subsystem.

Also the design flow rate to Secondary Alarm Station Room (692.0 -C1 2) was reduced to 200 cfm for personnel comfort reasons.In addition, this revision corrected the analysis to Include changes per DCN M02693-A.This DCN removed EBR AHUs face damper(s) prior to initial start-up of the unit.Rev. 14 calculated steady state room temperatures and cooling loads during normal (summer & winter) operating conditions and LOCA (summer) and LOOP (winter)accident conditions and evaluated adequacy of the coils and chillers.

Rev.14 reduced the lower limit of the environmental temperature from 60 0 F to 55 F in all areas served by EBR subsystem with the exception of the Unit1 Auxiliary Instrument Room.

This involved increasing the cooling load in the 250V Battery Board Room (C4) at El. 692.0, but the difference in room temperature was within the margin originally introduced in the calculation.

The conclusions are not affected, thus it was not necessary to rerun the AIRCOOL model. Also, the environmental drawings for the rooms are not affected and no successor calculations are impacted, so no revisions are required.CCRIS was corrected in response to PER 158531: Calculation MDQ00003120010065 was changed from a successor to a predecessor.

This revision Incorporated new heat loads from the Electrical Heat Loads Calculations (WBNEEBMSTI090022 R12, WBNEEBMSTI090042 R14 and WBNEEBMSTI090058 R8) which were revised recently to meet the new methodology and engineering guidelines.

The cooling load calculation WBNMEBMDQ0031000065 data is applicable to Unit 1 operation only. The heat load from Electrical Heat Load Calculations will be directly used for dual unit operation.

As a result of the update of new heat load, the Excel spreadsheet has been reiterated and the steady state temperatures in the Control Building -Electrical Board Room Areas (EL.692.0 and 708.0) for the dual unit operation are established and listed in Appendix 11.Revision 016 adds an unverified assumption for Unit 2 only. It assumes that Stage 3 of DCN 51656 will be cancelled for dual unit operation.

The unverified assumptions are discussed in Appendix 11 in Section 2.2 on page I of 194 Affected engineering judgments and assumptions were reviewed and were revised as necessary to ensure adequacy.Ultimate heat sink (UHS) temperature was not used as an input to the calculation analyses.

Therefore, existing calculation results will not be affected by changing the UHS technical specification temperature.

The installation of this equipment increases the heat load in 708.0-CO1 by 1,260 Watts, which results in a total theoretical electrical equipment heat load of 53,812 watts as reported in predecessor calculation WBNEEBMSTI090042 R01 6.This calculation documents the electrical equipment loads in the Ul Aux Instr. Rm from predecessor calculation WBNEEBMSTI090042, R016; however, the electrical equipment loads from predecessor calculation MDQ00003120010065 are utilized in the analysis (see Section 6.9, Item 3). Therefore, no computations, results, or conclusions are impacted, and no successor calculations are impacted.Appendix 11, which was developed to address dual unit operation, utilizes total design heat loads from predecessor calculation WBNEEBMSTI090042, R014 (67,176 W), which are higher than those documented in WBNEEBMSTI090042, R016 (64,132 W) for the Ul Aux. Instr. Rm.Therefore, no changes are made to Appendix 11. This is conservative.

/Component Performance Analysis for the Control Building -Electrical Board Room Areas (El. 692.0 and 708.0)Revision DESCRIPTION OF REVISION No.18 This revision incorporates the results of air flow measurements recorded in support of stage 3 of DCN 51656-A which were outside the G-37 acceptance criteria of +/-10%. PIC 52252-A is being issued for stage 3 of the DCN and revision 18 to the analysis provides the necessary documentation to adjust the design basis relative to normal and post LOCA temperature and relative humidity values accordingly.

Specifically, the measured air flow rates were as follows: The 24V and 48V Battery Board and Charger Room (692.0-C8) supply air flow rate was 724 cfm as compared to 1,000 cfm (as required by DCN 51656-A).The Secondary Alarm Station (692.0-C12) supply air flow rate was 346 cfm as compared to 200 cfm (as required by DCN 51656-A).The 250V Battery Board Room #1 (692.0-C4) supply air flow rate was 3,297 cfm as compared to 2,700 cfm (as required by DCN 51656-A).The Battery Room Exhaust Fan Room (692.0-C2) supply air flow rate was 419 cfm as compared to 255 cfm (as required by DCN 51656-A).These air flow rates were incorporated into the analysis and factored into each of the six cases associated with both normal plant operation and post LOCA conditions.

Overall, the changes had very minimal impact on the existing room temperatures and relative humidity values.Also, the 70% of design air flow case included in Appendix 9 was revised in consideration of the measured flows. Appendix 10 was deleted since stage 3 of DCN 51656-A is implemented.

It should be noted that the existing unverified assumption relative to Unit 2 / dual unit operation will not be valid since this revision does incorporate changes resulting from stage 3 of DCN 51656-A and PIC 52252-A. Revision of Appendix 11 to consider the measured air flow rates was outside the scope of revision 18.Impacts to the WBN UFSAR and Technical Specifications are reviewed under PIC 52252-A.Pages Revised/Replaced:

These changes significantly increase the cooling load within this room and require a change in supply airflow. More than adequate flow exists in the subsequent room, the Communications Room (692.0-C9).

The design flow rate in the SAS will be increased and the design flow in the Communications Room decreased.

The calculation was updated in revision 16 to address Unit 2 / Dual Unit Operation.

An unverified assumption for Unit 2 only assumes that stage 3 of DCN 51656-A will be cancelled.

Stage 3 of DCN 61656-A is not cancelled as evident by revision 18. Revision of the Appendix 11 analysis for Unit 2 / Dual Unit Operation was not within the scope of revision 19 and was not changed.Revision Bars have not been included on the pages showing the various Case computations.

The cooling load reported in predecessor calculation MDQ00003120010065 increased in the Unit 1 Auxiliary Instrument Room and was unchanged for the Computer Room. The change in cooling load in the Unit 1 Auxiliary Instrument Room caused an increase above the design temperature at the previously analyzed airflow, which was a measured value. This revision shows a requirement to increase the airflow to the Unit 1 Auxiliary Instrument Room to its design flow.DCN 58262 supports the security upgrades being made to the Secondary Alarm Station (692.0-C12).

The cooling load reported in predecessor calculation MDQ00003120010065 increased for the Secondary Alarm Station (SAS). The cooling load increased significantly and caused an increase above the design temperature at the previously analyzed airflow. This revision shows a requirement to increase the design flow to the SAS. More than adequate flow exists in the adjacent room, the Communications Room (692.0-C9).

The design flow rate in the SAS is increased and the design flow in the Communications Room decreased.

The theoretical loads reported on pages 6.5 and 6.6 have been updated to reflect the most recent revisions to the Electrical calculations.

The calculation was updated in revision 16 to address Unit 2 / Dual Unit Operation.

An unverified assumption for Unit 2 only assumes that stage 3 of DCN 51656-A will be cancelled.

Stage 3 of DCN 61656-A is not cancelled as evident by revision 18. Revision of the Appendix 11 analysis for Unit 2 / Dual Unit Operation was not within the scope of revision 20 and was not changed.Revision Bars have not been included on the pages showing the various Case computations.

Appendix 12 was added to provide the humidity for the Unit 2 Auxiliary Instrument Room. The calculation was updated on Revision 16 to address Unit 2 / Dual Unit Operation.

An unverified assumption for Unit 2 only assumes this stage 3 of DCN 51656-A will be cancelled.

Stage 3 of DCN 51656-A is not cancelled as evident by Revision 18. Revision of the Appendix 11 analysis for Unit 2 / Dual Unit Operation was not changed in support of stage 3 of DCN 51656-A and PIC 52252-A.Revision of the Appendix 11 analysis for Unit 2 Operation was not within the scope of Revision 021 and was not changed. Therefore; UVA was not removed.Successor calculations have been reviewed and the successor calculation WBNAPS4004 needs to be revised to reflect the minimum relative humidity for abnormal condition.

PL-1 1-4230 has been initiated to track this item.Ultimate heat sink (UHS) temperature was not used as an input to the calculation analyses.

Therefore, existing calculation results will not be affected by changing the UHS technical specification temperature.

The effect of Unit 2 dual operation on Unit I margins have been reviewed with no impact.Successor calculations have been reviewed and are not impacted by this revision.FSAR AND TECHNICAL SPECIFICATIONS HAVE BEEN REVIEWED AND ARE NOT AFFECTED BY THIS REVISION OF THE CALCULATION.

/ Component Performance Analysis for the Control Building Electrical Board Room Areas (EL. 692.0 and 708.0)Rev. 18 Prepared By: RAS Date: 8/11/2010 Rev. 18 Checked By: LRN Date: 8/11/201010 1.0 Purpose The purpose of this calculation is: To determine the steady state room temperatures and humidities for the spaces served by the Electrical Board Room (EBR) air conditioning (AC) system located on elevations 692.0 and 708.0 of the WBN Control Building.

Steady state temperatures and humidities were determined for normal plant operating conditions (summer & winter) and Design Basis Event (DBE) accident conditions of Loss of Coolant Accident (LOCA) during the summer and Loss of Offsite Power (LOOP) during the winter.The accident scenario for EBR AC system which results in minimum room temperatures is one which minimizes the cooling loads within the rooms served. This will occur during DBE LOOP (winter) without a concurrent LOCA since only safety-related loads would be present and additional loads required for LOCA event mitigation within certain rooms such as Unit 1 Auxiliary Instrument Room would be not present.The accident scenario for the EBR AC system which results in maximum room temperature is one which maximizes the cooling loads within the rooms served. This will occur during DBE LOCA (summer) without a concurrent LOOP since safety- and non-safety-related loads would be present.To evaluate the cooling loads and cooling capacities of both the AHU cooling coils and chiller.The temperature controller setpoint used in this evaluation for each of the AHUs is 68 0 F as changed by DCN D51656-A (Ref. 5.32) and PIC 52252-A (Ref. 5.63). This new setpoint RiB temperature is addressed in calculation EPM-WVC-101089 (Ref. 5.45).

Technical Justification:

The supply and the exhaust air to each room was balanced using information from reference 5.2 and in consideration of the air flow changes required by DCN D51656-A and PIC 52252-A. Also see Assumption 4.1.1 for use of exfiltration.

I 4.1.4 The abnormal maximum & minimum temperatures defined on the Environmental Data Drawings (EDDs) for the Turbine building were used as boundary temperatures when modeling the LOCA (summer) & LOOP (winter) DBE conditions.

Technical Justification:

Equipment in the Turbine Building is non-safety related, thus LOCA temperatures have not been specified on the EDDs for these areas (Ref. 5.8). The abnormal maximum & minimum temperatures specified were based on a postulated outside air temperature excursion of 102°F or 6 0 F, respectively.

In consideration of the DBE LOCA duration of 100 days, use of the abnormal maximum & minimum temperatures is considered to be conservative.

4.1.5 For calculation purposes the latitude of Watts Bar Nuclear Plant will be 35o.Technical Justification:

Per reference 5.12, page 24.13 the latitude of Athens, TN (the closest listing in Tennessee to WBNP) is 350. A latitude for Spring City, TN (i. e. WBNP) is not listed, so the closest latitude of 35 0 was chosen.4.1.6 The electrical cooling loads computed for the East and West Stairwells, 692 -C1 & C2, 708 -C1 &C2 were based on lighting only.Technical Justification:

The cooling loads in the stairwells were not computed in reference 5.26 or 5.28. Other than lighting, there are no significant sources of heat within the stairwell areas of the control building.

A conservative assumed heat load of 2 watt/ft was used based on information contained in Appendix B of Ref. 5.35.4.1.7 The temperature of the chilled water supplied to each AHU was assumed to range from as low as 42 0 F to as high as 48 0 F.Technical Justification:

A copy of SSD-0-ITC-31-51 1A-S is included as Attachment number 15. 0-ITC-31-51 1A controls the supply water temperature to each train A AHU. The setpoint temperature is specified as 45°F on this document with low and high "AS FOUND" limits of 42 0 F and 48 0 F, respectively.

Therefore, the analysis conservatively uses a 42°F supply water temperature when evaluating wintertime conditions.

Both 42 and 48 0 F setpoints were considered when evaluating summertime conditions in combination with the minimum and maximum chilled water flow rates (also see Assumption 4.1.8). Use of these values conservatively minimizes the computed space temperatures during winter cases and maximizes space temperatures during the summer cases. In addition, using these extremes conservatively maximizes the predicted cooling load for the chiller.

/ Component Performance Analysis for the Control Building Electrical S Board Room Areas (EL. 692.0 and 708.0)Rev. 18 Prepared By: RAS Date: 8/11/2010 Rev. 18 Checked By: LRN Date: 8/11/2010 4.0 Assumptions (cont'd)4.1 Justified Assumptions (cont'd)4.1.8 Chilled water flow rate to the AHUs was assumed to vary from a minimum of 216 gpm to a maximum of (284 gpm +10%).Technical Justification:

Table 9.6, "Design Parameters for Primary Safety-Related HVAC System Components" of the Control Building HVAC System Description (reference 5.1) specifies a minimum flow rate to each AHU of 216 gpm. Reference 5.1 is referred to in note 7 of the chilled water flow diagram (reference 5.41) as the source for minimum flow rates. Since a minimum flow rate to each AHU minimizes the heat removed from the spaces, 216 gpm was used for the normal and LOCA during summer cases to predict maximum room temperatures.

A second set of summer time normal/LOCA cases were modeled which consider the maximum flow rates in combination with the minimum chilled water temperature in order to compute the maximum chiller load under these conditions.

For the winter time cases, the flow rate to each AHU was considered to be 10% greater than the values currently shown on reference 5.41. This results in flow rates of 216

• 1.1 = 238 gpm for one AHU and 284

• 1.1 = 312 gpm for the other. Use of these max/min flow rates for the specific case under consideration supports a conservative estimation of the resulting space temperatures.

4.1.9 Assumed the Secondary Alarm Station (SAS) & Unit 2 Auxiliary Instrument rooms are occupied by one person, Unit 1 Auxiliary Instrument Room, Computer Room and Communications Room are populated by two people, and the remaining rooms are unoccupied.

Technical Justification:

The number of people in the rooms used in the previous revisions (to calculate the latent load) was unrealistically high. Only the SAS, room C12-E1.692.0' has one person stationed there permanently.

The remaining rooms are normally unoccupied.

Conservatively, consider Unit 1 Auxiliary Instrument Room, Computer Room and Communications Room are populated by 2 people and Unit 2 Auxiliary Instrument Room by one person.4.1.10 The internal loads during LOOP (winter) conditions are defined only for the following rooms: 692.0-C1, 692.0-C10, 708.0-Cl, 708.0-C3 & 708.0-C4, as shown in Table 6.8. For the remaining rooms @El. 692.0 & 708.0 the internal loads were assumed to be zero.Technical Justification:

It is conservative to consider no internal loads for the remaining rooms @ El.692.0 & 708.0 since this results in the lowest environmental temperature limits for the rooms served by the EBR air conditioning subsystem.

4.2 Unverified Assumptions (UVAs): The calculation was updated on revision 16 to address Unit 2 / Dual Unit Operation.

An unverified assumption for Unit 2 only assumes that stage 3 of DCN 51656-A will be cancelled.

Stage 3 of DCN 51656-A (as modified by PIC 52252-A) is not cancelled and is incorporated into the analysis for Unit 1 on revision 18. Revision of Appendix 11 for Unit 2 / Dual Unit Operation was not within the scope of revision 18 and was not changed.

1. Simplified Flow Diagrams depicting conservative air flow rates for normal (summer & winter)operating conditions and LOCA (summer) & LOOP (winter) accident conditions are shown in Appendixes 2 and 3, respectively.

Also see Assumptions 4.1.1,4.1.2

& 4.1.3.2. The outdoor design minimum wintertime temperature is 13 0 F for normal operating and LOOP accident conditions per Reference 5.13. This value represents the 99% winter design dry bulb for Athens, Tennessee as listed in Reference 5.12.3. Cooling loads associated with equipment located in all areas other than the stairwells are based on Reference 5.29, Table 8.1.4. Overall heat transfer coefficients

("U" factors) were obtained from Ref. 5.20.5. Room dimensions were taken from architectural drawings Refs. 5.14, 5.15, 5.16 and 5.18.Also see note 16.6. During all but the LOOP condition in winter, the full equipment cooling loads are considered.

Refer to Sections 6.5 through 6.8 for electrical loads.7. This note deleted on revision 14.8. During LOCA (summer) and LOOP (winter) accident conditions, heaters and/or humidifers are not considered since neither are classified as safety related nor backed by diesel power (Ref.5.39). A failure of one non-safety related heater in the "On" position concurrent with LOCA is addressed in Ref. 5.55.9. During normal plant operation, the duct heaters will operate intermittently as required in response to their respective thermostat controller.

Duct heaters were credited during the normal operational winter case. They also would be available to function during warmer months depending on the thermostat setpoint chosen, thus "NORMAL (SUMMER CASE 2)" credited heaters 0-HTR-31-85

& -87 (see pg. 7.9.1).10. This note deleted on revision 14.11. Relative humidity for each room was obtained from the psychrometric chart data using the calculated humidity ratio and the dry bulb air temperature for each room.12. Calculated temperatures/humidity during the normal cooling and heating modes of operation were compared to the criteria values.

Cooling / Heating Load and Equipment

/ Component Performance Analysis for the Control Building Electrical Board Room Areas (EL. 692.0 and 708.0)Rev 14 Prepared By: 4 Date: 03/11/04 Rev. 14 Checked By: Re1S Date: 03/18/04 6.9 Methodology (cont'd)13. The supply air temperature is controlled by a by-pass damper system (formally a face and bypass damper until the face damper portion was deleted by DCN M02693-A, Ref. 5.33). A thermostat, which is mounted in the return air duct to each AHU, senses the mixed return air temperature to the AHUs and modulates the bypass damper in each AHU in an attempt to maintain a constant temperature.

If the return air temperature is greater than 68 0 F, the by-pass damper may be fully closed. If the return air temperature is less than 68 0 F, the bypass damper may be fully open. Therefore, even during the LOOP (winter) case with the bypass damper fully open, a significant portion of the total air flow will continue to flow through the cooling coils. A methodology was developed on revision 14 to estimate the air flow rate through the coil during this condition and is detailed in Appendix 7. During the normal plant operation and LOCA condition cases concurrent with the maximum outside design temperature, full flow is required through the coil since the return air temperature to the AHU is greater than the controller set point temperature of 68 0 F. During the normal plant operation case concurrent with the minimum outside air temperature, the bypass dampers will be in a throttled position with the majority of the flow continuing through each coil (see Section 7.12 for specifics).

During the LOOP case concurrent with the minimum outside design temperature, the bypass damper was determined to be fully open (see Section 7.13 for specifics).

14. All average earth temperatures were taken from Reference 5.17, page 12.9.15. Calculation EPM-GEB-061290 (Ref. 5.38), page 14 lists the required ventilation flow rate to maintain the hydrogen concentration under 2%. This value is much less than the measured flow rate to each battery room. Therefore, the airflow rates used in this calculation are more than adequate for hydrogen removal.16. The wall, ceiling and floor materials, and thickness of the structures were taken from the drawing references listed in Section 5.0. Also see note 5.17. The summertime humidity ratio (specific humidity) used was 0.0133 # moisture/#

dry air based on 95 OF DB, 74 OF WB, Ref. 5.13.18. The winter outdoor air humidity ratio during the LOOP condition (specific humidity is 0.0003 #moisture/#

dry air) was based on 13 OF DB, 20% Relative Humidity.

Since Ref. 5.12 does not indicate a wet bulb temperature, 20 % Relative Humidity was used based on Ref. 5.13 which reflects a normal minimum temperature of 13 OF DB and normal minimum relative humidity of 20 %. Since the rooms are not required to maintain a defined humidity range during a LOOP, this specific humidity was only used to provide a general humidity estimate in each room.18a. The winter outdoor air humidity ratio during normal plant operation (specific humidity is 0.0003 # moisture/#

dry air) was based on 60 OF DB, 5% Relative Humidity since the 144 KW outside air duct heater raised the outside air temperature from 13 OF DB to 60 OF DB, with no moisture added.

During normal plant operation in the winter, the specific humidity leaving the AHU was considered the same as during the normal cooling mode (.0084 # moisture/#

dry air-See Section 7.3) since the cooling coils operate during both summer and winter conditions.

19. The EBR AHUs are equipped with temperature controllers (0-TC-31-335, -336, -337 & -338)with their associated temperature elements located in the return air duct of each AHU. These temperature controllers govern the position of the cooling coil bypass damper associated with each AHU such that the return air temperature entering the air handling unit remains at the required setpoint value. Note that the cooling coil face dampers were removed as discussed previously (See Ref. 5.33 & Attachment 12).Each of the Excel spreadsheets presented in Sections 7.8 through 7.13 uses the same basic methodology in determining the steady state temperatures for each of the rooms served by the EBR air conditioning system. The process involves a trial and error iterative solution until assumed room temperatures (which feed into the heat transmission portion of the spreadsheet) and computed room temperatures (computed from the summation of the transmission loads with the internal loads, and the supply air temperature) are within a fraction of a degree (approximately 0.1 0 F). At the same time, the mixed EBR AHUs return air temperature and relative humidity are used as input to the AIRCOOL program to compute an off-coil air temperature from each EBR AHU. The supply air temperature to each room from the AHUs is then calculated based on this off-coil temperature, heat addition from the supply fans/motors, and the effects of steam injection, if applicable.

Only copies of the final iterations are included in the calculation.

Sections 7.8, 7.9, and 7.11 include AIRCOOL models of the supplemental cooling AHUs serving the computer room. Since these units are non-safety-related, they were only credited in the normal summertime cases (Section 7.8 & 7.9) & LOCA (Section 7.11) summertime case which maximizes the cooling loads on the chiller.20. Performance of each EBR AHU was predicted by the AIRCOOL program. Required coil data for the program are listed in Attachments 6 and 7. The EBR AHU coils were replaced via DCN M-02693-A (Ref. 5.33) with identical TRANE type DD coils as those manufactured in 1976 per information contained in contract 75678C (Ref. 5.34). A benchmarking case was run based on the performance data listed on dwg. 47A373-1 (Ref.5.22 and Attachment 14).The minimum sensible heat removal capacity of each AHU is specified as 715,000 Btu/hr and the total (sensible

+ latent) minimum heat removal capacity is 890,000 Btu/hr at the conditions specified on Ref. 5.22. The AIRCOOL model performance prediction at these same conditions is 738,023 Btu/hr (sensible) and 836,543 Btu/hr (total) which agrees well with the requirement.

The sensible heat removal capability predicted by AIRCOOL is within approximately 3% of the value specified on Ref. 5.22. A copy of the AIRCOOL report for this benchmark case is included as Appendix 6.

In a similar manner (see note 20), an AIRCOOL benchmarking case was run for the computer room supplemental cooling AHUs based on data presented in Attachment

5. A copy of the AIRCOOL results is presented in Appendix 8. Drawing 47A373-26 (DCA-P05297-109) indicates a minimum sensible heat removal capacity of 127,910 Btu/hr. The AIRCOOL model conservatively predicts 118,186 Btu/hr for the same entering water, air temperature conditions and air flow rate. These AHUs are not safety related, however, they do receive chilled water from the EBR chillers.

Therefore, they can contribute to the total EBR chiller load for certain cases.22. Adequacy of the coils is based on computed steady state room temperatures and humidities being within the design parameters of the EDDs (Ref. 5.5 to 5.7). Also the heat removal capability (Total / Sensible / Latent) from the AIRCOOL Program was compared to the final iterated cooling load (Total / Sensible / Latent) to determine if there is adequate coil capability.

23. The EBR AHUs (Contract 77K38-821350

-Ref.5.23 & Attachment

6) were purchased for 90 gpm per coil or 180 gpm of chilled water per AHU. However, flow diagram 1-47W865-7 (Ref.5.41) shows that AHUs A-A & C-B each receive 216 gpm, and AHUs B-A & D-B each receive 284 gpm. The computer room supplemental AHU (Contract 79K38-825328

-Attachment 5 &11) receives 22 gpm of chilled water per 1-47W865-12 (Ref. 5.46). These flow rates are used in the AIRCOOL program (see Sections 7.8 to 7.13).I CALCULATION SHEET Calculation Number: EPM-MCP-071689 WBN / Units 1 & 2 Page: 7Z L-/L

The brake horsepower is 34.5.The heat released from the fan and the 34.5 BHP motor is 98,435 Btuh (Ref. 5.12, pg 26.8).For normal & LOCA summer operating conditions, the minimum evaluated air flow rate is 32,063 / 2 or 16,032 CFM per AHU (See Appendix 2).Therefore, ATFAN = 98,435 / (1.08 x 16,032 CFM) = 5.69°F In order to determine the leaving air temperature of the AHU, 5.69 OF was added to the leaving air temperature of the coil to account for motor and fan heat addition.

Therefore, the AHU supply air temperature (at guaranteed vendor data entering air temperature conditions) is 50.9 + 5.69 = I 56.59°F or 56.6 0 F. Since only heat (no moisture) is added to the air stream, the relative humidity i decreases with an increase in wet bulb temperature.

Therefore, from the psychrometric chart the final leaving supply AHU temperature is 56.6 F DB, 51.5 OF WB (.0069 # moist/# dry air).

h2 = Enthalpy of Air (after humidification)

From the psychrometric chart, the air volume (specific volume) @ 50.9 °FDB, 49.0 °FWB is 13.00 ft 3 per pound of dry air.Air Mass (ma) = 32,063 CFM x 1 # / 13.00 ft 3 = 2466 # / min dry air (REF. 5.2) )gig Enthalpy of Dry Air (hi) = 19.8 Btu / # of dry air before humidification (at 50.9 0 FDB, 49.O 0 FWB leaving coil temperature)

Note: The steam generator supplies a total of 226 # of steam / hr or 113 # / hr to each AHU.Since 32,063 CFM is the total airflow rate for both AHU's operating, then 226 # of steam / hr lm, is used as the mass flow rate.Water Mass Flow @ Saturation (mw) = 226 # of steam / hr x 1 hr / 60 min = 3.77 # / min of steam (Ref. 5.19)Humidity Ratio (w 1) = 0.0069 # of water / # of dry air (at 50.9 °FDB, 49.0 °FWB)Note: This humidity level is applicable for LOCA (summer) and LOOP (winter) conditions since the humidifiers are non-safety-related and considered as not operating during this modes.Enthalpy of Saturated Water vapor (steam) (hw) = 1163 Btu / # of steam (at 15 psi steam press +14.7096 psia = 29.7096 psia) (Ref. 5.12 Chapter 6.11)

Note: This value is used also during normal (winter) operating condition since the steam injection system will be in service during this condition.

7.4 Determination of the Final Leaving Air Temperature at the AHU after Steam Iniection for Normal Plant Operation (summer and winter) Based on the Guaranteed Vendor Data 7.4.1 Normal Operation (Summer): As discussed above, the fan and motor heat raises the temperature of the leaving air by 5.69 0 F.Since the air leaving the AHU is 50.9 OF + 5.69°F = 56.6 OF, this temperature will be used to I determine the final supply air temperature to the rooms (See Ref. 5.58).Note: The coil leaving air is humidified before entering the fan. For the purpose of establishing the final temperature, it does not make any difference if the fan heat is added before or after humidification.

See Psychrometric Chart (Ref. 5.30) -Appendix 5.Plot w 2 = 0.0084 # of water / # of dry air (See Section 7.3) on the Psychrometric Chart and draw a straight line across the chart. This is the specific humidity of the coil leaving air temperature after steam injection.

Plotting the leaving air temperature of the cooling coil (50.9 OF DB, 49 OF WB) and adding 5.69 OFI DB, draw line straight across (since no moisture is being added at this point) until it reaches 56.6 OF DB. Read 51.5 OF WB. From Section 7.3, the enthalpy of the steam is 1163 BTU / # of steam.Thus, according to Eq. (44) (see Section 7.3), the condition line on the Psychrometric Chart connecting States I and 2 must have a direction of (Ah / AW) = 1163.

This second line is the condition line. State 2 is established at the intersection of the condition line with the horizontal line extended from 0.0084 # of water / # of dry air. At that intersection read 57.0 OF DB, 54'F WB. Therefore, the final leaving temperature of the AHU is 57.0 OF DB*, 54 OF WB*, 0.0084 # of water /# of dry air. This is a 6.1 OF DB rise (57 OF DB minus 50.9 OF DB) from the cooling coil to the discharge of the AHU. Thus, the total air temperature rise through each EBR AHU, including the addition of steam is 6.1 OF. A 6.1 0 F temperature rise was used in each of the normal summertime cases (sections 7.8 and 7.9).*Note: Based on the guaranteed vendor data 7.4.2 Normal Ooeration (Winter): Since there is less steam in the air because of the greater assumed air flow rate of 40,632 cfm (Appendix 3), then for the simplification of this calculation the temperature rise during this operating condition is calculated as follows: From Section 7.2, the leaving air temperature from the coil is 50.9 OF DB, 49 OF WB. The temperature rise through the fan is 5.69 OF (from above). Therefore 5.69 OF + 50.9 OF = 56.59 OF. I From this Section the AHU final leaving dry bulb temperature (including fan heat and steam injection) is 57 OF. Therefore 57 OF- 56.59 OF = 0.41 OF is the temperature rise due to the steam injection.

This I is used in Section 7.12 for normal operation during winter conditions.

7.5 Supply Air Temperature Rise through the Fan and Fan Motor for LOCA (summer) and LOOP (winter) Conditions The supply air temperature leaving the AHU can be estimated using the following equation: Ts = Tz + q/(1.08 x Q)where Ts = Supply Air Temperature Tz = Air Temperature leaving the cooling coil q = Heat released from motor in -mach in 1.08 = Conversion Coefficient Q = Air Flow Rate CFM The electrical board room AHU is a draw through type with the fan and the motor in the air stream.The AHU motor is a 50 HP (Ref. 5.31). The brake horsepower is 34.5.The heat released from the fan and the 34.5 BHP motor is 98,435 Btuh (REF. 5.12, pg 26.8).For LOCA (summer) condition, the air flow rate is 32,063 / 2 or 16,031 CFM per AHU (See Appendix I 2).

Since the steam injection system could also be in service during this mode (no concurrent LOOP), the same total temperature rise as in the normal cooling mode of 6.1 0 F was used (see Section 7.4 above). The spreadsheets of Sections 7.10 and 7.11 both reflect a temperature rise of 6.10 F.For the LOOP winter operating condition, the steam injection system was not modeled as functioning since it is non-safety-related and not backed by diesel power. Therefore, ATfan = 98,435 / (1.08 x 20,316 CFM) = 4.5 0 F.

Communication room supplemental cooling is provided by two air conditioning units (See Attachment

4) located within the room. See N3-30CB-4002, Section 3.1.11 (Ref. 5.1). The computer room has supplemental cooling provided by two AHUs (See Attachment 5), located in the corridor which receive chilled water from the EBR chillers (See N3-30CB-4002, Section 3.1.12, Ref. 5.1). Only the computer room supplemental AHUs were integrated into the Excel spreadsheets.

See Attachments 5 and 11 and Appendix 4 for the computer room supplemental AHU coil parameter used in AIRCOOL Program. The computer room supplemental cooling units were credited in spreadsheet sections 7.8, 7.9, and 7.11. A 2.63°F temperature rise (see below) was added to the AIRCOOL predicted off-coil temperature to account for motor and fan heat addition.

This is based on assuming both the AHU fan and motor are within the air stream and are both downstream of the cooling coil. (It should be noted that each computer room supplemental cooling AHU motor is mounted externally to the unit. Therefore, heat from the motor will not go directly into the air stream. Assuming the motor heat is within the air stream is conservative since it results in a slightly higher supply air temperature).

The temperature rise was computed based on the equation presented in Section 7.2 as follows: Motor BHP = 7.5 hp = 22,700 Btu/hr (motor in driven equipment in) (Atts. 5, 11, and table 24, page 26.25 of Ref. 5.24)Air flow rate = 8,000 cfm (Ref. 5.2)Air density factor = 1.08 (density factor for air at approximately 70 OF)Temp Rise = 22,700 Btu/hr/(1.08*8,000)

This case also conservatively maximizes the predicted room temperatures.

The EXCEL spreadsheet (see pg.7.8.2 to.7.8.24) and AIRCOOL models (see pg.7.8.25 to 7.8.30) were iterated until the mixed return air temperature (both dry and wet bulb) to the AHU coils calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were approximately equal. This equates to approximately Tr = 76.1'F (see pgs. 7.8.24 & 7.8.27) which is I significantly greater than the controller setpoint of 68 0 F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: Tz = 51.07 OF (estimated air side outlet temperature for each EBR AHLU based on the AIRCOOL model; see pg. 7.8.27)At = 6.1 OF (total air temperature rise thru AHU including steam injection temperature rise; see Section 7.4)Ts=Tz+At=

57.2 OF Since the computer room supplemental AHU is also credited in this normal cooling mode, an AIRCOOL model of this unit is included in this section (see pg. 7.8.28 to 7.8.30). This model was also iterated until the assumed entering air conditions used in the AIRCOOL model were approximately equal to the room temperature I humidity conditions computed in the speadsheet.

These values are approximately 70'F and 50% relative humidity.

LOAD AS SHOWN IN TABLE 6.5 S95°F PRESSURIZING AIR i COMPUTER ROOM SUPPLEMENTAL AHU RUNNING go HEATERS 0-HTR-31-83 (SUPPLY AIR TO ROOMS @ EL. 692) AND 0-HTR-31-85 (COMPUTER ROOM)ARE RUNNING SINCE THE PRELIMINARY ANALYSIS INDICATED THAT TEMPERATURE IN ROOM C9, EL. 692.0 AND ROOM C3, EL. 708.0 WILL FALL BELOW THE TEMPERATURE SWITCHES SETPOINT TEMPERATURE OF 68 OF, THUS THE HEATERS WILL BE RUNNING.This case conservatively maximizes the cooling capability of the EBR AHUs by modeling the maximum chilled water flow rate concurrent with minimum chilled water temperature.

This case was performed to conservatively predict the maximum load on the chillers during normal summer time operation since this value is reported in the system description (Ref. 5.1) Table 9.6.The EXCEL spreadsheet (see pg.7.9.2 to.7.9.24) and AIRCOOL models (see pg. 7.9.25 to 7.9.30) were iterated until the return mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were approximately equal. This equates to approximately Tr = 73.8 0 F (see pg.7.9.24) which is significantly greater than the controller setpoint of 68°F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: TZ(B-A) = 45.79 OF (estimated air side outlet temperature for EBR AHU B-A based on the AIRCOOL model; see pg. 7.9.30)TZ(A-A) = 46.13 OF (estimated air side outlet temperature for EBR AHU A-A based on the AIRCOOL model; see pg. 7.9.27)Tz = 46.0 OF (calculated average air temperature just downstream of coil)At = 6.1 OF (total air temperature rise thru AHU including fan/motor and steam injection temperature rise; see Section 7.4)Ts=Tz+At=

52.1 °F Since the computer room supplemental AHU is also credited in this normal cooling mode, an AIRCOOL model of this unit is included in this section (see pg. 7.9.31 to 7.9.33). This model was also iterated until the assumed entering air conditions used in the AIRCOOL model were approximately equal to the room temperature I humidity conditions computed in the speadsheet.

These values are approximately 65.7°F and 59.3% relative humidity.I This page replaced by Revision 20.

LOAD AS SHOWN IN TABLE 6.6 (9 95 0 F PRESSURIZING AIR 99 COMPUTER ROOM SUPPLEMENTAL AHU IS NOT RUNNING (6 STEAM INJECTION SYSTEM IN SERVICE (SEE SECTION 7.5)This case conservatively minimizes the cooling capability of the EBR AHUs by modeling the minimum chilled water flow rate concurrent with maximum chilled water temperature.

This case also conservatively maximizes the predicted room temperatures by assuming no concurrent LOOP. The EXCEL spreadsheet (see pg.7.10.2 to 7.10.24) and AIRCOOL models (see pg. 7.10.25 to 7.10.27) were iterated until the mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were approximately equal. This equates to approximately 83.9 0 F (see pg. 7.10.24) which is significantly greater than the controller setpoint of 68 0 F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: Tz = 50.97 OF (estimated air side outlet temperature for each EBR AHU based on the AIRCOOL model; see pg.7.10.27)

At = 6.1 OF (total air temperature rise thru AHU including steam injection temperature rise; see Section 7.5)Ts=Tz+At=

57.1 °F Since the computer room supplemental AHUs are not safety-related and this case is predicting maximum LOCA room temperatures, these were not credited.

For this scenario, the computer room is only cooled by air supplied by EBR AHUs as reflected in the spreadsheet.

LOAD AS SHOWN IN TABLE 6.6 9- 95 0 F PRESSURIZING AIR (go COMPUTER ROOM SUPPLEMENTAL AHU IS RUNNING (a STEAM INJECTION SYSTEM IN SERVICE (SEE SECTION 7.5)This case conservatively maximizes the cooling capability of the EBR AHUs by modeling the maximum chilled water flow rate concurrent with minimum chilled water temperature.

This case was performed to conservatively predict the maximum load on the chillers during accident conditions since this value is reported in the system description (Ref. 5.1) Table 9.6.The EXCEL spreadsheet (see pg.7.11.2 to 7.11.24) and AIRCOOL models (see pg. 7.11.25 to 7.11.33) were iterated until the mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were approximately equal. This equates to approximately 78.4°F (see pg.7.1 1.24) which is significantly greater than the controller setpoint of 68 0 F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: TZ(B.A) = 45.71 °F (estimated air side outlet temperature for EBR AHU B-A based on the AIRCOOL model; see pg.7.11.27)

TZ(A.A) = 45.96 OF (estimated air side outlet temperature for EBR AHU A-A based on the AIRCOOL model; see pg. 7.11.30)Tz = 45.835 OF (calculated average air side outlet temperature for each EBR AHU)At = 6.1 OF (total air temperature rise thru AHU including steam injection temperature rise; see Section 7.5)Ts =Tz + At= 51.9 OF Since the computer room supplemental AHUs are also credited in this LOCA cooling mode, an AIRCOOL model of one of these units is included in this section (see pg. 7.11.31 to 7.11.33).

This model was also iterated until the assumed entering air conditions used in the AIRCOOL model were approximately equal to the room temperature I humidity conditions computed in the speadsheet.

These values are approximately 65 0 F and 47% relative humidity.This page replaced by Revision 20.

LOAD AS SHOWN IN TABLE 6.7 (a 60'F PRESSURIZING AIR (g COMPUTER ROOM SUPPLEMENTAL AHU IS NOT RUNNING A- LATENT LOADS DUE TO PERSONNEL CONSERVATIVELY NOT CONSIDERED This case conservatively evaluates the cooling capability of the EBR AHUs by modeling the minimum chilled water temperature.

Since the normal summertime Case 2 (discussed in Section 7.9) already considered concurrently both minimum chilled water temperature and maximum chilled water flow in an effort to maximize the chiller load, this combination was not run in the spreadsheet below. Increasing the chilled water flows to 10% would only slightly reduce the room temperatures beyond what has been computed below.The EXCEL spreadsheet (pg.7.12.2 to 7.12.24) and AIRCOOL models (pg.7.12.25 to.7.12.55) were iterated until the mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were both equal to 68.8'F.In order to achieve this condition, the following non-safety related heaters (see Section 7.6) were credited as running @ 100% capacity.

0-HTR-31-83, 1-HTR-31-87

& 2-HTR-21-89.

It is recognized that control of these heaters is via local thermostats, but it is reasonable to credit their operation on order to maintain comfortable temperatures (i.e., greater that 64 0 F).Iterations between the speadsheet and AIRCOOL indicated that full flow through the coils would not exist during this winter time condition because the mixed return air temperature would be greater than the controller setpoint of 68 0 F. Therefore, the bypass damper would modulate open to a throttled position.

An additional spreadsheet was developed on the previous Rev. 13 which accounts for various bypass flow rates in computing a mixed off-coil temperature.

This same speadsheet was utilized In Rev. 20 with the following modifications:

1) The controller setpoint was changed from 75°F to 68OF (Originally done in Revision 14)2) The total flow rate through each AHU was changed to 20,253 cfm to agree with the flow rates as shown on the simplified flow diagram Appendix 3 Otherwise, the equations remained unchanged.

The results indicate approximately 25,000 cfm of the total flow will continue to flow through the coils and approximately 15,506 cfm will bypass (see pg.7.12.25).

Calculated EBR AHU supply temperature Ts: Tz = 53.3 OF (resulting mixed air AIRCOIL temperature upstream the fans;see this section, pg. 7.12.25)q = 98435 Btuh (see Section 7.2)Q = 20,253.0 cfm (See Appendix 3; one fan only)At = 0.41 OF (steam injection temperature rise; see Section 7.2 & 7.4)Ts = Tz + At + q I (1.08 x Q) = 58.2 OF This page replaced by Revision 20.

LOAD AS SHOWN IN TABLE 6.813 0 F PRESSURIZING AIR (144 KW HEATER NOT ENERGIZED) i99 COMPUTER ROOM SUPPLEMENTAL AHU IS NOT RUNNING A- LATENT LOADS DUE TO PERSONNEL CONSERVATIVELY NOT CONSIDERED This spreadsheet (see pg. 7.13.2 to 7.13.24) and AIRCOOL model (see pg.7.13.25 to 7.13.30) were iterated until the mixed return air temperature (both dry and wet bulb) to the EBR AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL program were approximately equal.This equates to approximately 57 0 F which is significantly lower than the controller setpoint of 68'F. Unlike the normal winter operating condition evaluated in Section 7.14, the bypass damper will be fully open during this operating condition.

Since the face dampers were removed, a significant portion of the return air flow will continue through the EBR AHU coils. A trial and error solution based on the relative pressure drop associated with the flow through the coil and around the coil through the bypass damper was performed and documented in Appendix 7.Results indicate that approximately 30% of the total flow will continue go through the coil, and the remaining 70%will flow through the bypass damper. In this flow contition, calculated EBR AHU supply temperature Ts: LAT = 42.3 OF (average temperature based on AIRCOOL results for 57 0 F EAT;see pg. 7.13.27 & 7.13.30)Tr = 57.0 OF (based on the weighted average; see pg. 7.13.24)Total return flow to one AHU Q = 20,252.8 cfm (see Appendix 3)Considered that 30% of the total flow passes through the coils, Tz = ([0.3Q x LAT) + (0.7Q x Treturn)]/Q Tz = 52.6 OF (weighted average temperature downstream of coil/damper) q = 98435 Btuh (see Section 7.2)Ts =Tz + q / (1.08 x Q) = 57.1 OF Since the computer room & communications room supplemental AHUs are not safety-related, they will not be energized during this LOOP scenario.

ii m Page le.2 STATEMENT OF PROBLEM/ABSTRACT (CON'T)Cooling -LOCA Conditions:

All rooms, during LOCA cooling mode, are maintained below the maximum temperatures as shown on the Environmental Data Drawings except for the Mechanical Equipment Room C2, 24V& 48V Battery Board Room C8, Secondary Alarm Station C12 on EL 692, and U1 Aux Instrument Room C1 on EL 708. Since the calculated room temperatures are based on theoretical loads, the calculated room temperatures are artificially high. However, walkdown package # WDP-WBN-O-LMN-008 is being prepared to measure the temperatures (supply, return, transfer air temperatures), along with a work order to measure the airflow rates so that the actual cooling loads can be computed for both normal and LOCA conditions.

Subsequently this calculation will be revised to determine the actual room temperatures which are expected to be lower.During Cooling Mode (LOCA Conditions), the coils are adequate since the Aircool Program determined that the coils can achieve an AHU leaving air temperature of 53.06 OF as compared to the iterated leaving AHU of 53 IF while maintaining all rooms within the temperature limits of the Environmental Data Drawings, except C2, C8 and C12 on EL 692, and C1 on EL 708 which are above the temperature limits (See Chart above "Cooling Load -LOCA Operation).

Comparing both AHUs total capacity of 1,578,658 BTUH to the total cooling load 1,087,377 BTUH, the coils have more than adequate capacity.Heating -Normal Conditions:

All rooms, during the normal heating mode, are maintained above the minimum temperature and humidity limits as shown on the Environmental Data Drawings.

This is based on the modulating face and bypass dampers in full bypass position (full heating).

The calculated retum air temperature is 77.1 'F. The return air temperature controller is set for 75 OF. Therefore, since the calculated return air temperature is greater than 75 °F, the face and bypass dampers will modulate to cool the rooms to a lower temperature until the return air temperature is 75 OF. This will lower the calculated room temperatures slightly, however all are expected to remain above the minimum values shown on the applicable Environmental Data Drawings.

The computed relative humidity for rooms C4, C5, C8 and C12 on EL 692, and C3 on EL 708 are slightly below the values shown on the Environmental Data Drawings.Heating -LOCAJLOOP Conditions:

All rooms, during the LOCA heating mode, are maintained above the minimum temperatures limits as shown on the Environmental Data Drawings.

This is based on the modulating face and bypass dampers in the full bypass position (full heating).

The calculated return air temperature is 76.3 OF. The return air temperature controller is set for 75 OF. Therefore, since the calculated return air temperature is greater than 75 OF, the face and bypass damper will modulate to cool the rooms to a slightly lower temperature until the retum air temperature is 75 OF. This will lower the calculated room temperatures slightly, but they are expected to remain above the minimum values shown on the Environmental Data Drawings.

Rooms' steady state temperatures and humidity results were or Environmental Data Drawings to determine whether the rooms meet the design parameters as defined int The resultant data are as follows: 116 Cooling -Normal Conditions:

All rooms, during the normal cooling mode, are maintained below the maximum temperatures and humidities as shown on the Environmental Data Drawings except for the Computer Room C3 on EL 708, which has calculated relative humidity of 25.94%. This is below the minimum relative humidity of 40% relative humidity currently shown on the applicable Environmental Data Drawings.During Cooling Mode (Normal Conditions), the cooling coils are adequate since the Aircool Program determined that the coils can achieve a lower AHU leaving air temperature of 52.56 OF than the iterated leaving AHU air temperature of 55 OF while maintaining the rooms within the design temperature limits of the Environmental Data Drawings (See chart above "Cooling Load, Normal Operation").

They were transferred to Watts Bar Nuclear Plant, transfer contract 75746A, for use as supplemental AHUs for the Computer Room, EL 708, in the Control Building.

The original YCN UNID #'s were IVC-MAHU-126-A for item #143 and IVC-MAHU-127-B for item # 141 under the original contract 79K36-825328.

They were tagged with Mark #'s 47A373-102 and 103 for use in the Computer room at Watts Bar.American Air Filter's coil division was purchase by the MlQuay. The Replacement Parts division of M!Quay (phone 763-553-5403) faxed all the information for that particular coil part number AFF part #20-60-3W5-8 (See Attachment 11). The part number was obtained from the transfer contract 75746A vendor drawing R107D1189398-D corresponding to YCN AHU UNID numbers IVC-MAHU-126-A and IVC-MAHU-127-B.

EPMMCP071689 Rev.20 Page: I of 10 I APPENDIX 7 LOCA I LOOP CONDITION (WINTER)Determine the ratio of air flowing through the bypass damper to the air which will continue to flow through the coil during this condition.

This is a trial and error solution.Assume 25% of the total flow through the AHU passes through the coil and the remaining passes through the bypass damper when it is in full open position.

The pressure drop through each flow path will be computed and the iteration process continued until each is approximately equal.Total flow rate for this scenario is: 40506 cfm per train (see Appendix 3), or 20253.0 cfm per AHU.25% of AHU flow rate Q: 5063 cfm A = 35 ft 2 (coil cross-sectional area from calc. EPM-MCP-090589 R3, pg. 23 -copy included in this Appendix)V=Q/A= 145 ft/min Attachment 5 to calc. EPM-MCP-090589 provides coil pressure drop as a function of coil face velocity.Since the chart only ranges from 300 to 800 fpm, a AP at 143 fpm was linearly extrapolated based on available data: Velocity (fpm) AP / 2 rows 300 0.060 400 0.092 145 X X = 0.060 -(0.092 -0.060) (300 -145) = 0.0104 in w.g.(400- 300)AP = 0.0104 x 4 (8 rows total) = 0.042 in w.g. or 0.04 in w.g Thus AP across coil = 0.04 in w.g. ]Now look at AP associated with the remaining 75% flow passing through bypass damper.Use Section 7-7 of ASHRAE Chapter 33, Appendix B "Damper, Rectungular, Opposed Blades" (copy included in this Appendix).

L / R = NW / 2 (H + W)where H = 18 " W = 108 " See Dwg. SDC-73-08 Contract75K35-8 N = 3 (page 6 of this Appendix)j.3119-01 Thus L / R =1.29 This page replaced by Revision 20.I Calculation Identifier:

-Co' = 0.41 APt' = Co x Pvo = 0.0324 in w.g.Total pressure drop associated with 75% of the total flow passing through the bypass damper in the full open position: p 0.0410 + 0.0324 = 0.0734 in w.g. (damper)0.0734 / 0.04 (damper) (coil)Thus, greater flow will exist through the coil.This page replaced by Revision 20.

(damper)0.0639 approximately equal to 0.0787 (damper) (coil)This indicates that slightly greater than 70% of the total flow will pass through the bypass damper. Using 70%is conservative for purposes of evaluating a LOOP wintertime condition.

Also shown are the total and static pressure gradients referenced to atmospheric pressure.For all constant-area sections, the total and static pressure losses are equal. At diverging sections 3 and 7, the velocity pressure decreases, the absolute total pressure decreases and the absolute static pressure can increase.

The static pressure increase at these sections is known as static regain.At converging sections 2 and 6, the velocity pressure in-creases in the direction of air flow, and the absolute total and absolute static pressures decrease.At the exit, section 8, total pressure loss depends on the shape of the fitting and the flow characteristics.

Exit loss coef-ficients can be greater than, less than or equal to one (see Table B-2). The total and static pressure grade lines for the various coefficients are shown in Fig. 2. Note that for a loss coefficient less than one, static pressure upstream of the exit is less than atmospheric pressure (negative).

The static pressure just upstream of the discharge fitting can be calculated by substracting the upstream velocity pressure from the upstream total pressure.At section 1, the total pressure loss depends on the shape of the entry. The total pressure immediately downstream of the entrance equals the difference between the upstream pressure, which is zero (atmospheric pressure), and the loss through the fitting. The static pressure of the ambient air is zero; several diameters downstream, static pressure is negative, algebraically equal to the total pressure (negative) and the velocity pressure (always positive).

System resistance to airflow is noted by the total pressure grade line in Fig. 2. The fan inlet and outlet system effect factors caused by the fan and system interactions are not shown; only system resistances are shown. To obtain thefan static pressure requirement for fan selection where the fan total pressure is known, use: i~14.I p, =p+p, where p 1 = total pressure, in. H 2 0 p -static pressure, in. H2 0 Instruments Instruments for measuring pressure and velocity discussed in Chapter 13, with respect to range, precisiot limitations.

The manometer is a simple and useful meat measuring partial vacuum and low pressure.

It is a prima strument and often is used as a standard for calibrating instruments.

The static, velocity and total pressures in a system relative to the atmospheric pressure are measured a Pitot tube connected to a manometer.

Pitot tube cons tion and locations for traversing round and rectangular, are presented in Chapter 13.SYSTEM ANALYSIS The pressure losses for each section of a duct system calculated by Eq. (15).

[see Eq. (24) and (25))Frictional Losses for Duct Liners SwimIO conducted tests on duct liners of varying densities, surface treatments, transverse joints (workmanship) and methods of attachment to sheet metal ducts. As a result of these tests, Swim recommends for design the absolute roughness values in Table 2, 0.015 ft for spray-coated liners and 0.005 ft for liners with a facing material cemented onto the air side. In both cases, the roughness factor includes the resistance offered by mechanical fasteners and assumes good joints. Liners cut too long and fastened to the duct cause much more loss than a liner cut too short; therefore, any fabrication error in liner length should be on the short side.Liner density does not significantly influence flow resistance.

Frictional Losses for Fibrous Glass Ducts Based on limited manufacturers' data, rigid fibrous glass duct is in the medium rough category (see Table 2). More ex-tensive data are necessary to establish the range of absolute roughness factors for various fibrous glass boards commer--ýally available.

DYNAMIC LOSSES Dynamic losses result from flow disturbances caused by fit-tings that change the airflow path's direction and/or area.These fittings include entries, exits, transitions and junctions.

Local Loss Coefficients The following dimensionless coefficient is used for fluid resistance, since this coefficient has the same value in dynamically similar streams, i.e., streams with geometrically similar stretches, equal values of Reynolds number and equal values of other criteria necessary for dynamic similarity.

The fluid resistance coefficient represents the ratio of total pressure loss to velocity pressure at the referenced cross sec-tion o. _1 I II', Ii (36)0 It.IL z 0 0 0 (LU where Co = local loss coefficient for section o, dimensionless Ap, fitting total pressure loss, in.

For ease of calculation, dynamic losses are assumed to be concentrated at a section Oocal) and to exclude friction.

Frictional losses must be con-sidered only for relatively long fittings.

Generally, fitting fric-tion losses are accounted for by measuring duct lengths from the centerline of one fitting to that of the next fitting. For fit-tings closely coupled (less than six hydraulic diameters apart), the flow pattern entering subsequent fittings differs from the flow pattern used to determine loss coefficients.

Adequate data for these situations are unavailable.

LOAD AS SHOWN IN TABLE 6.6 i 95F PRESSURIZING AIR TEMP AND STEAM INJECTION IN SERVICE (SEE SECTION 7.5)This case conservatively minimizes the cooling capability of the EBR AHUs by modeling the minimum chilled water flow rate concurrent with maximum chilled water temperature.

This case also conservatively maximizes the predicted room temperatures by assuming no concurrent LOOP. The EXCEL spreadsheet (see pg. 2 to 25) and AIRCOOL model (see pg. 26) were iterated until the mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were approximately equal. This equtes to approximately 88.4°F (see pg. 24) which is significantly greater than the controller setpoint of 68 0 F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: Tz = 49.91 OF (estimated air side outlet temperature for each EBR AHU based on the AIRCOOL model; see pg. 28)At = 6.1 °F (total air temperature rise thru AHU including steam injection temperature rise; see Section 7.5)Ts =Tz + At = 56.0 °F Since the computer room supplemental AHUs are not safety-related and this case is predicting maximum LOCA room temperatures, these were not credited.

For this scenario, the computer room is only cooled by air supplied by EBR AHUs as reflected in the spreadsheet.

Appendix 11 -Dual Unit Operation Analysis APPENDIX 11 -Dual Unit Operation Analysis 1. PURPOSE The purpose of this Appendix is:* Determination of the steady state room temperatures and humidity for dual unit operation.

As part of the WBN Unit 2 Construction Completion Project, electrical heat load calculations referenced by this calculation were revised not only to reflect Dual Unit Operation (newly energized cables, lights, and equipment) but also to more accurately reflect actual electrical heat loads during different normal and off-normal conditions.

The heat load from electrical heat load calculations (Ref. 3.1, 3.2 and 3.3) are directly used as design input in this appendix.* To determine potential impact for completing stage 3 of DCN 51656 for dual unit operation.

Calculation EPMMCP071689 Rev.016 assesses the proposed changes to be performed by DCN 51656. Stage 3 of this DCN was not completed since Systems Engineering was unable to get the air flows adjusted to within the G-37 requirements.

Section 6.5 of Appendix 11 provides the potential impact on the EQ design room temperatures if the air flow to the Secondary Alarm Station was reduced from 695 cfln to 200 cfm.The detailed updated electrical load calculations used in Appendix 11 are listed in Section 3.2. Assumption 2.1 Justified Assumption 2.1.1 For dual unit operation, 90% of current design flow rates based on the flow diagram was used for the summertime normal plant operation and a LOCA, while 110% of current design flow rates was used for the wintertime normal plant operation and a DBE LOOP. Table I in Appendix 11, Page 9, lists the 90% of current design flow rate and 110% of current design flow rates, respectively.

Technical Justification:

Currently, the Stage 3 of DCN 51656 has not been implemented yet. Using the flows listed in Table 1 is conservative since lower airflow rates in summertime will result in higher room temperature while higher airflow rates will reduce the room temperature in winter time.The other justified assumptions for this appendix are identical to that in Section 4.1.2.2 Unverified Assumption 2.2.1 Stage 3 of DCN 51656 will be cancelled for dual unit operation.

According to preliminary analysis, the implementation of Stage 3 of DCN 51656 will result in very high room temperature in Secondary Alarm Station (EL.692-C12) which is over 104 TF.This page is added by Rev.016 I I lCalculation sheet Document:

Appendix 11 -Dual Unit Operation Analysis The other DCNs and Unit 1 civil and mechanical drawings associated with previous revisions of this calculation have been reviewed and determined to not merit the inclusion of an unverified assumption for the purpose of dual unit operation.

This case also conservatively maximizes the predicted room temperatures.

The EXCEL spreadsheet (see pg.1 Ito 33) and AIRCOOL models (see pg.34 to 39) were iterated until the mixed return air temperature (both dry and wet bulb) to the AHU coils calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were approximately equal. This equtes to approximately Tr = 83.3oF(see pg.33) which is significantly greater than the controller setpoint of 68 0 F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU.At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: Tz = 51.48 OF (estimated air side outlet temperature for each EBR AHU based on the AIRCOOL model; see pg.36)At = 6.1 OF (total air temperature rise thru AHU including steam injection temperature rise; see Section 7.4)Ts =Tz+ At = 56.8 OF Since the computer room supplemental AHU is also credited in this normal cooling mode, an AIRCOOL model of this unit is included in this section (see pg.37 to 39). This model was also iterated until the assumed entering air conditions used in the AIRCOOL model were approximately equal to the room temperature I humidity conditions computed in the speadsheet This page replaced by Revision 016.

THE PRELIMINARY ANALYSIS INDICATED THAT TEMPERATURE IN ROOM C3, EL. 708.0 WILL FALL BELOW THE TEMPERATURE SWITCHES SETPOINTTEMPERATURE OF 68 OF, THUS HE HEATER FOR COMPUTER ROOM WILL BE RUNNING. THE HIEATR FOR EL.692 ARE CONSIDERED AS RUNNING FOR CONSERVATIVE PURPOSE.This case conservatively maximizes the cooling capability of the EBR AHUs by modeling the maximum chilled water flow rate concurrent with minimum chilled water temperature.

This case was performed to conservatively predict the maximum load on the chillers during normal summer time operation since this value is reported in the system description (Ref. 5.1) Table 9.6.The EXCEL spreadsheet (see pg.41 to 63) and AIRCOOL models (see pg. 64 to 72) were iterated until the return mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) Input to the AIRCOOL models were approximately equal. This equates to approximately Tr = 81.56F (see pg.63) which is significantly greater than the controller setpoint of 68 0 F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: TZ(4-AI = 46A8 OF (estimated air side outlet temperature for EBR AHU B-A based on the AIRCOOL model; see pg.69)TZ(A.A) = 46.85 OF (estimated air side outlet temperature for EBR AHU A-A based on the AIRCOOL model; see pg.66)Tz = 46.7 OF (calculated average air temperature just downstream of coil)At = 6.1 OF (total air temperature rise thru AHU including fanimotor and steam injection temperature rise; see Section 7.4)Ts :Tz + At: 52.8 OF Since the computer room supplemental AHU is also credited in this normal cooling mode, an AIRCOOL model of this unit is included in this section (see pg.70 to 72). This model was also iterated until the assumed entering air conditions used in the AIRCOOL model were approximately equal. to the room temperature I humidity conditions computed in the speadsheet.

EVALUATED FOR INFORMATION ONLY go MINIMUM CHILLED WATER FLOW RATES OF 216 GPM TO EACH EBR AHU r. MAXIMUM CHILLED WATER SUPPLY TEMPERATURE OF 48°F g LOCA CONDITION INTERNAL (ELECTRICAL)

LOAD IN PAGE 4 IN APPENDIX 11 S95°F PRESSURIZING AIR Cm COMPUTER ROOM SUPPLEMENTAL AHU IS NOT RUNNING di STEAM INJECTION SYSTEM IN SERVICE (SEE SECTION 7.5)This case conservatively minimizes the cooling capability of the EBR AHUs by modeling the minimum chilled water flow rate concurrent with maximum chilled water temperature.

This case also conservatively maximizes the predicted room temperatures by assuming no concurrent LOOP. The EXCEL spreadsheet (see pg.74 to 96) and AIRCOOL models (see pg. 97 to 99) were iterated until the mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) Input to the AIRCOOL models were approximately equal. This equtes to approximately 88°F (see pg. 96) which is significantly greater than the controller setpoint of 68°F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: Tz = 51.6 0 F (estimated air side outlet temperature for each EBR AHU based on the AIRCOOL model; see pg.99)At = 6.1 OF (total air temperature rise thru AHU including steam Injection temperature rise; see Section 7.5)Ts=Tz+At=

57.7 OF Since the computer room supplemental AHUs are not safety-related and this case Is predicting maximum LOCA room temperatures, these were not credited.

For this scenario, the computer room is only cooled by air supplied by EBR AHUs as reflected in the spreadsheet.

LOAD AS SHOWN IN PAGE 5 IN APPENDIX 11 go 95°F PRESSURIZING AIR g COMPUTER ROOM SUPPLEMENTAL AHU IS RUNNING& STEAM INJECTION SYSTEM IN SERVICE (SEE SECTION 7.5)This case conservatively maximizes the cooling capability of the EBR AHUs by modeling the maximum chilled water flow rate concurrent with minimum chilled water temperature.

This case was performed to conservatively predict the maximum load on the chillers during accident conditions since this value is reported In the system description (Ref. 5.1) Table 9.6.The EXCEL spreadsheet (see pg.101 to 123) and AIRCOOL models (see pg.124 to 132) were iterated until the mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry andwet bulb) input to the AIRCOOL models were approximately equal. This equtes to approximately 83PF (see pg.123) which is significantly greater than the controller setpoint of 68 0 F. This simply means that the bypass damper will be fully closed and the entire air flow (with the exception of any leakage) will pass through the cooling coil of each EBR AHU. At this condition, the calculated mixed supply air temperature from the EBR AHU (Ts) is: Tz(B-A) = 45.75 OF (estimated air side outlet temperature for EBR AHU B-A based on the AIRCOOL model; see pg.126)TZ(A-) = 46.18 OF (estimated air side outlet temperature for EBR AHU A-A based on the AIRCOOL model; see pg. 129)Tz = 45.97 OF (calculated average air side outlet temperature for each EBR AHU)At = 6.10 OF (total air temperature rise thru AHU including steam injection temperature rise; see Section 7.5)Ts =Tz +,At 52.1 OF Since the computer room supplemental AHUs are also credited in this LOCA cooling mode, an AIRCOOL model of one of these units is Included in this section (see pg.130 to 132). This model was also iterated until the assumed entering air conditions used in the AIRCOOL model were approximately equal to the room temperature I humidity conditions computed in the speadsheet.

NORMAL OPERATION INTERNAL (ELECTRICAL)

LOAD AS SHOWN IN PAGE 6 IN APPENDIX 11 fib 60°F PRESSURIZING AIR r COMPUTER ROOM SUPPLEMENTAL AHU IS NOT RUNNING rE LATENT LOADS DUE TO PERSONNEL CONSERVATIVELY NOT CONSIDERED This case conservatively evaluates the cooling capability of the EBR AHUs by modeling the minimum chilled water temperature.

Since the normal summertime Case 2 (discussed in Section 5.2, Appendix 11 ) already considered concurrently both minimum chilled water temperature and maximum chilled water flow In an effort to maximize the chiller load, this combination was not run In the spreadsheet below. Increasing the chilled water flows to 10% would only slightly reduce the room temperatures beyond what has been computed below.The EXCEL spreadsheet (pg.134 to 156) and AIRCOOL models (pg.157) were iterated until the mixed air temperature (both dry bulb and wet bulb) to the AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb) input to the AIRCOOL models were both equal to 68 0 F.In order to achieve this condition, the following non-safety related heaters (see Section 7.6) were credited as running @ 100% capacity:

0-HTR-31-83, 1-HTR-31-87

& 2-HTR-21-89.

It is recognized that control of these heaters is via local thermostats, but It is reasonable to credit their operation on order to maintain comfortable temperatures (i.e., greater that 64 0 F). I(Note)ote: The AIRCOOL model was not re-run for this case and the final mixinci temperature was obtained by extrapolatlon with using current atL Iterations between the speadsheet and AIRCOOL Indicated that full flow through the coils would not exist during this winter time condition because the mixed return air temperature would be greater than the controller setpolnt of 68 0 F. Therefore, the bypass damper would modulate open to a throttled position.

An additional spreadsheet was developed on the previous Rev. 13 which accounts for various bypass flow rates In computing a mixed off-coil temperature.

This same speadsheet was utilized in Rev. 14 with the following modifications:

1) The controller setpoint was changed from 75 0 F to 68OF 2) The total flow rate through each AHU was changed to 20,020.5 cfm to agree with the flow rates as shown on the simplified flow diagram Appendix 3 Otherwise, the equations remained unchanged.

The results Indicate approximately 36,000 cfm of the total flow will continue to flow through the coils (see pg.157).Calculated EBR AHU supply temperature Ts: Tz = 47.6 OF (resulting mixed air AIRCOIL temperature upstream the fans;see this section, pg. 157)q = 98435 Btuh (see Section 7.2)Q = 20,020.5 cfm (See Appendix 3; one fan only)At = 0.45 OF (steam injection temperature rise; see Section 7.2 & 7.4)Ts Tz + At +q I(1.08 x Q) 52.6 OF This page replaced by Revision 016.

LOAD AS SHOWN IN IN PAGE 7 IN APPENDIX 11 Cm 13 0 F PRESSURIZING AIR (144 KW HEATER NOT ENERGIZED) b COMPUTER ROOM SUPPLEMENTAL AHU IS NOT RUNNING r LATENT LOADS DUE TO PERSONNEL CONSERVATIVELY NOT CONSIDERED This spreadsheet (see pg. 159 to 181) and AIRCOOL model (see pg.182 to 187) were Iterated until the mixed return air temperature (both dry and wet bulb) to the EBR AHU coils (calculated in the spreadsheet) and the assumed entering air temperature (dry and wet bulb). input to the AIRCOOL program were approximately equal.This equates to approximately 50OF which Is significantly lower than the controller setpoint of 68 0 F. Unlike the normal winter operating condition evaluated in Section 5.5 in Appendix 11, the bypass damper will be fully open during this operating condition.

Since the face dampers were removed, a significant portion of the return air flow will continue through the EBR AHU coils. A trial and error solution based on the relative pressure drop associated with the flow through the coil and around the coil through the bypass damper was performed and documented in Appendix 7.Results Indicate that approximately 30% of the total flow will continue go through the coil, and the remaining 70%will flow through the bypass damper. In this flow contition, calculated EBR AHU supply temperature Ts: LAT = 42.4 OF (average temperature based on AIRCOOL results for 64.5 0 F EAT;see pg.184 & 187)Tr = 64.5 OF (based on the weighted average; see pg.184)Total return flow to one AHU Q = 20020.5 cfm (see Appendix 3)Considered that 30% cools off by AHU.Tz = ([0.3Q x LAT) + (0.7Q x Treturn)]/Q Tz = 57.9 OF (weighted average temperature downstream of coil/damper) q = 98435 Btuh (see Section 7.2)Ts =Tz + q 1 (1.08 x Q) = 62.4 OF Since the computer room & communications room supplemental AHUs are not safety-related, they will not be energized during this LOOP scenario.

SUMMARY

997,178 1,600 As shown in Table 6.1-1, calculated temperatures and relative humidities in each room are less than the values currently shown on the applicable EDDs (Ref. 5.5 through 5.7).As shown in Table 8.1-1A, at a controller setpoint of 68OF, the following cooling loads and cooling.capacities were computed.

Final cooling loads are less than cooling capacities, thus adequate cooling capacity exists during this NORMAL (summer) cooling scenario.TABLE.6.1-1A (Cooling Loads & AHU Heat Duty -Normal Summer -Case 1)Cooling Final Computer AHU A-A AHU B-A TOTAL Load Cooling Room (216 gpm) (216 gpm) three (3)Name Load AHU ** AIRCOOL AIRCOOL

Appendix 11 -Dual Unit Operation Analysis 6.5 Evaluation of DCN 51656 Potential Impact on Dual Unit Operation Calculation EPMMCP071689 Rev.016 assesses the proposed changes to be performed by DCL 51656.Stage 3 was included in this DCN to rebalance the air flow of the Control Building Electrical Board Room Areas HVAC system such that air flow to the Secondary Alarm Station was reduced from 695 cfm to 200 cfm. Systems Engineering was unable to get the air flows adjusted to within the G-37 requirements specified in stage 3. As a result, PIC 52252 was initiated to disposition the measured air flows.The calculation concluded that this reduction in air flow did not result in excessive temperatures because the calculation at that time used electrical heat loads from MDQ00003120010065 (field measured heat loads for single unit operation) rather than the theoretical heat loads from the Electrical Engineering Branch electrical heat loads calculations.

An analysis was performed to determine potential impact on the design room temperature for dual unit operation if stage 3 of DCN 51656 was implemented.

In this preliminary analysis, the airflow rate used in this spread sheet is the same as Revision 15 with implementation of Stage 3 of DCN 51656. Based on the result of this analysis, the room temperature in Secondary Alarm Station (EL.692-C12) with issued electrical heat loads for dual unit operation is 106 'F for Normal Operation (Summer Case 1) and 107 OF for LOCA Operation (Summer Case 1) operating case, which are much higher than the design limits for normal (90 0 F) and LOCA (79 OF) conditions.

The spread sheet for this preliminary analysishas been uploaded to FILEKEEPER (EPMMCP071689R16_Preliminary.xls, # 313161).Considering that the room temperature in Secondary Alarm Station (EL.692-C

12) will be over 104 'F for normal and LOCA cases with rebalanced flow rate data, it is recommended that the Stage 3 of DCN 51656 should be cancelled for dual unit operation.

Appendix 12- Evaluation of Relative Humidity in Unit 2 Auxiliary Instru ent Room during LOCA Condition 1. Purpose This Appendix is to determine the maximum relative humidity in Unit 2 Aux Instrument Room durng the LOC conditions.

According to environmental drawing 2-47E235-17 and -19 Revision 0 (Reference 2.1 & 2.2), the maximum temperature uring a LOCA is 91 OF for elevation 692.0 and 94 OF for elevation 708.0 with a specific humidity of 140 grains of moisture per pound of dry air (0.02 pound of moisture per pound dry air). The Electrical Board Room (EBR) Air Handling Units (AHUs) provides 36,400 cfm air (30,665 cfm return air plus 5,735 cfm outside air) to the various rooms on Elevation 692.0 and 708.0. The Unit 2 Auxiliary Instrument Room is located on elevation 708.0 and receives 8425 cfm of the 36,400 cfm from the EBR AHUs.2.

Design Input Data 3.1 LOCA Condition Auxiliary Equipment Room (Reference 2.2)IsElevation 708.0 -Temperature, F 88 Specific Humidity, pound of moisture per pound dry air 0.02 3.2 For the normal operation, the intake flow rate from outside to Electrical Board Room air conditioning unit is 5,735 cfm and the total return air flow is 30,665 cfm (Reference 2.4).3.3 The air temperature, humidity ratio, and relative humidity for Unit 2 Auxiliary Instrument Room with normal maximum temperature are 84.77F, 0.0084 lb water vapor/lb dry air (58.8 grains) and 33%; respectively. (Reference Appendix 11, Page 30 of 194).3.4 For LOCA condition, the Unit 2 Auxiliary Instrument Room humidity ratio is 0.0069 lb water vapor/lb dry air (48.3 grains) and the steady state room temperature (dry bulb) is 88.4 °F (Appendix 11, Page 93 of 194).Humidity in Main Control Room and Auxiliary Instrument Room is desired to be higher than 20% as lower than 20% humidity may affect function of touch screens and will affect operability of Unit 2 QPAMS.For the Electrical Board Room AHUs, the total return airflow from is 30,665 cfm and the intake flow rate from outside is 5,735 cfm, which is about 16 % of total return flow rate.Considering that the amount of intake flow rate from outside is relatively small, the impact of the variation of outside conditions from normal maximum condition (95 'F with specific humidity of 0.0133 lb moisture/lb air- Section 6.9.17) to LOCA maximum condition (88 "F with specific humidity of 0.02 lb moisture/lb air) on cooling coil performance is not significant.

Referring to Psychometric Chart for Air-Steam Mixtures (Reference 2.5), relative humidity for LOCA steady state room conditions temperature 88.4 OF and humidity ratio 0.0069 lb water vapor / lb of dry air (48.3 grains) is about 24% for the Unit 2 Auxiliary Instrument Room. The humidity ratio and the steady state room temperature were retrieved from Page193 of the Appendix 11 of this calculation.

Note that this humidity ratio is for condition when the heaters are assumed to be not operating.

If the heaters are assumed in operation, the humidity ratio is 0.0084 lb water vapor/ lb of dry air (58.8 grains) the relative humidity in the room is about 29% at 88.4 OF.4.0 Conclusion Based on the above analysis, the temperature and relative humidity in Unit 2 Auxiliary Instrument Room still remains as 88.4°F and 24% RH during LOCA condition and humidifiers not in operation.
