The degree of change in the electrical loads for the above mentioned area was found to be less than 1 percent. The previous electrical load for El. 755.0-C12 during normal and LOCA operation was 100,931 watts. The present calculated electrical load is 101,003 watts.Therefore, the increase in load will have no impact on the results presented in this calculation. Consequently, the numerical values in Revision 10 of this calculation do not reflect the changes in the electrical loads presented in WBN EEB-MS-TI09-0042, Revision 11.

This calculation is applicable to Unit 2 based on the following: .Appendix C of this calculation was added to present calculation results for dual unit operation.

An unverified assumption has been added as part of this revision.

The unverified assumption only applies to the Unit 2 portions of this calculation. Refer to section 4.2 of this calculation for further information. When review of Revision 12 was performed for Unit 2 applicability, the following needed to be changed for support of both Units 1 and 2:* Revision 12 utilizes calculation MDQ00003120010065 for electrical heat load values. The results of calculation MDQ00003120010065 are applicable only for single unit operation. Calculation MDQ00003120010065 is not being revised for dual unit operation. Revision 13 of EPMLCP072489 directly utilizes design inputs to calculation MDQ00003120010065 for electrical heat load values. The design inputs are specifically dual unit operation applicable revisions of calculations WBNEEBMSTI090022, WBNEEBMSTI090058 and UVA 4:2.1.A review of DCNs listed in the revision log prior to Revision 013 revealed no DCNs of impact to dual unit operation. This revision also makes a correction to the heat loads used for Room 755-C1 for the purposes of the Single Unit Operation heating load analysis. Previous revisions had erroneously transposed the heat loads for this room and had also not corrected the heat loads for equipment that is mounted in the duct work. This had resulted in non-conservative results for minimum room temperatures for this room. This issue is documented in PER 207043. Both the Single Unit Operation (Section 9.4) and Dual Unit Operation (Appendix C) summaries conclude that the Environmental Data Drawing for Room 755-Cl (Ref. 5.3.7) warrant revision.This revision concludes that the Environmental Data Drawing for Room 755-C3 (ref. 5:3.4) needs to be revised to reflect higher temperatures in this room during Dual Unit Operation. 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 total heat load for MCR (EL.755 -C12) is 136,598 watts, which is bounded by the value (148,032 watts) used in Revision 013. The results in this calculation are conservative. Thus, no change needs to be made in this revision and the UVA listed in Section 4.2.1 of Revision 013 was removed.Existing design margins are not adversely affected by this revision; therefore, existing design inputs and previously made engineering judgments and assumptions are not invalidated. The effect of Unit 2/dual unit operation on Unit 1 margins has been reviewed with no impact.Successor calculations have been reviewed and the successor calculation WBNAPS4004 needs to be revised to reflect the minimum relative humidity for abnormal condition. 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.

4.1 Justified

Assumptions

4.1.1 Infiltration

load will not be considered. TECHNICAL JUSTIFICATION: Control Building Rooms are pressurized to prevent infiltration of contaminated air from surrounding rooms. Therefore, the possibilities of infiltration is minimal and it will not be considered. 4.1.2 For calculation purposes the latitude used for the Watts Bar Nuclear (WBNP) Plant will be 320.TECHNICAL JUSTIFICATION: Per reference 5.7, page 24.13 the latitudes of cities in TN is 350. However, per ASHRAE Handbook of Fundamentals (Ref. 5.7) closest latitude is R12 320 for data on solar effects. Use of 320 latitude is conservative (i.e. provides more heat).4.1.3 AHU flow rates TECHNICAL JUSTIFICATION: The design air flow data specified per ref. 5.2.1 have +/-10%margin as stated in General Engineering Specification G-37.For conservatism, a (-10%) margin, i.e. 90% flow rate, was analyzed to obtain AHUs' total cooling loads, and a (+10%) margin, i.e. 110% flow rate, was analyzed to obtain total heating loads.Measured flow rates for rooms C4 to C10 (data in parentheses per ref. 5.2.1) are higher than design flow rates. These rates were not considered for the heating (normal & LOCA)conditions since they'll generate less conservative results in relation to the projected rooms'temperatures. 100% design flow rates are depicted at DIAGRAM I to 4 on pg. 30 & 31. Notes on pg. 30& 31 provide an additional information how the balanced flow rates have been used in R12 this calculation. 4.1.4 Not Used THIS PAGE REPLACED BY REV.12 LTVAN CALCULATION SHEET Calculation Identifier: EPM-LCP-072489 Rev.: 12 Plant: WBN / 1 & 2 Page: /3#

4.1 Justified

Assumptions (cont'd)4.1.5 Heating & Cooling Load Evaluation. TECHNICAL JUSTIFICATION: Non-safety related equipment is not considered operational during LOCA. Thus, duct heaters will not be operable during LOCA heating, and steam humidifiers also are not operable during LOCA heating and cooling. Also conservatively, during winter condition (normal & LOCA heating operations), heat load from people and lighting is not considered, and only 25%(1) of the generated equipment heat is taken into account.Also see Notes on pages 18 & 18A. R12 4.1.6 LOCA Temperature in Turbine Building TECHNICAL JUSTIFICATION: Equipment in the Turbine Building is non-safety related, thus LOCA temperature is not specified in the Turbine Building rooms (ref. 5.3.5 & 5.3.6).Conservatively, used abnormal temperatures for LOCA cooling & heating conditions. 4.1.7 G -Line Wall between Auxiliary Building & Control Building (North wall)TECHNICAL JUSTIFICATION: G -Line wall is 36" thick up to elevation 765.17" and then gradually increases to 60" thickness (ref. 5.1.15). For the calculation purposes the entire wall height was considered as 36" thick. It is conservative for the establishing transmission cooling loads. The impact on the transmission heating load is insignificant; use of the lower U-factor (for the thicker wall) can reduce room temperature by less than 0.2 0 F.4.1.8 LOCA Minimum Temperature TECHNICAL JUSTIFICATION: For adjacent auxiliary and turbine building rooms use R12 normal minimum temperatures when LOCA minimum temperatures were not identified in EDD 47E235-Series drawings.(1) Except mechanical equipment, main control and relay rooms; see Note in italic font on pg. 19 THIS PAGE REPLACED BY REV.12 lU] TVAN CALCULATION SHEET Calculation Identifier: EPM-LCP-072489 Rev.: 11 Plant: WBN / 1 & 2 Page:.

9.0 CONCLUSION

(cont'd)9.4

SUMMARY

(cont'd)As shown in sections 9.1 & 9.2, calculated rooms' steady state temperatures and humidity levels for the Control Building Main Control Room and associated rooms are acceptable for Normal and Accident (LOCA) heating operating mode at 110% air flow rates except for Mechanical Equipment Room 755.0-Cl. With the corrected heating mode heat loads for Room 755.0-Cl utilized in this revision, the steady state temperatures for both Normal and LOCA operation are found to be approximately 3YF below the respective minimum temperature limits for this room. Room 755.0-Cl contains no equipment such as batteries that could be affected by temperatures lower than 60'F. Therefore, Environmental Data Drawing 47E235-24 (Ref. 5.3.7) should be revised to reflect a Normal operating mode minimum temperature of 60'F and a LOCA operating mode minimum temperature of 59°F for Room 755.0-Cl.This page added by Revision 013 Calculation Identifier:

Cooling and Heating Load Analysis, Main Control Room HVAC Appendix C -Dual Unit Operation Analysis The purpose of this appendix is to determine the dual unit operation cooling load in the Main Control Room and associated rooms of the Control Building el. 755.0. The room conditions for each individual room of el. 755.0 of the control building will also be determined. The tables found in this appendix are available from Excel spreadsheet EPMLCP072489REV13.xls that can be retrieved from File Keeper (Document ID #313149).Room Electrical Heat Loads This Appendix utilizes electrical heat loads from the relevant dual unit operation applicable revisions of electrical heat load calculations WBNEEBMSTI090022 and WBNEEBMSTI090058 (References 5.8.8 and 5.8.9 respectively) and UVA 4.2.1. A room-by-room explanation of electrical heat loads is provided below-Mechanical Equipment Room (755.0-Cl) Reference

5.8.8 accounts

for a lighting heat load of 1,462 Watts for this room for either Normal or LOCA conditions. There are no electrical cable heat loads for this room.Reference 5.8.8 also accounts for 18,178 Watts and 22,430 Watts for Normal and LOCA conditions respectively for equipment heat loads. However, many of these equipment heat loads are either not running or the heat generating equipment is mounted within the airstream of the ductwork or equipment housing. The main body of this calculation identifies the equipment that is located in the airstream on pages 22 and 23. Subtracting out these heat loads results in heat load reductions of 13,200 Watts and 17,700 Watts for Normal and LOCA conditions respectively. Additionally, Reference 5.8.8 also accounts for heat generated from Control Building Pressurization Fans that are abandoned per Reference 5.2.1. This results in a further 600 Watt reduction for both Normal and LOCA conditions. Lastly, an additional 187.5 watts can be eliminated for LOCA conditions for taking credit that the Spreading Room Supply Fan is not running concurrent with a CRI signal (Reference 5.6). The resulting equipment heat loads are 4,378 Watts and 3,943 Watts for Normal and LOCA conditions respectively. Adding the lighting heat loads of 1,462 Watts, the total electrical heat load is 5,840 Watts (19,927 Btu/hr) and 5405 Watts (18,443 Btu/hr) for Normal and LOCA conditions respectively. These heat loads are far less than the heat load of 32,002 Btu/hr that was used for the single unit operation only part of the calculation. The 32,002 Btu/hr amount was determined by analysis of actual measured temperatures and HVAC system flow rates. Therefore, for conservatism, the 32,002 Btu/hr value will be retained for the Normal and LOCA conditions cooling load analysis part of this appendix. The heating load analysis part of this calculation will use the 4378 Watts (14,938 Btu/hr) and 3943 Watts (13,454 Btu/hr) values because those values will be conservative for that purpose.This Appendix added by Revision 013.

Cooling and Heating Load Analysis, Main Control Room HVAC Women's Toilet (755.0-C2) Reference

5.8.9 states

a reduced electrical heat load amount of 160 Watts (546 Btu/hr)for this room. However, the higher 992 Btu/hr value used by the single unit operation only part of the calculation will be retained for conservatism for the cooling load analysis part of this appendix. For conservatism, a value of 0 Btu/hr will be used for the heating load analysis part of this appendix. The same also goes for Corridor 755.0-C15, the West Stair, and the East Stair in the heating load analysis.Corridor, Locker Rm & Showers, Conference Rm, Technical Support Center, NRC Offices and Corridor (755.0-C3, -C6, -C7, -C8, -C9, -C14, -C18, and -C19)All of these rooms have higher electrical heat loads from References 5.8.8 and 5.8.9 than those used in the single unit operation only part of this calculation. Therefore, for the purposes of the cooling load analysis part of this appendix and conservatism, the new higher electrical heat loads from References 5.8.8 and 5.8.9 will be utilized.For the heating load analysis, only 25% of the heat loads from equipment is utilized for these rooms. The new equipment heat loads from References 5.8.8 and 5.8.9 for these rooms are the same or lower than those used in the single unit operation only part of this calculation except for 755.0-C14. Therefore, for conservatism, the lower heat loads are always used.Kitchen, Men's Toilet, Shift Engineer's Office, Conference Rm & Telephone (755.0-C4, -C5, -C10, -C16, and -C17)Reference

5.8.9 demonstrates

heat load reductions for these rooms. Therefore, for the sake of conservatism in the cooling load analysis part of this appendix, the electrical heat loads used in the single unit operation only part of this calculation are retained.For the heating load analysis, again only 25% of the heat loads from equipment is utilized. The equipment heat loads in Reference 5.8.9 for these rooms are the same as was used in the single unit operation only part of this calculation. Relay Room, & DPSO Shop (755.0-C13 and -C20)References 5.8.8 and 5.8.9 account for a higher electrical heat load that that used in the single unit operation only part of this calculation. Therefore, for the sake of conservatism in the cooling load analysis part of this appendix, the new electrical heat loads totaled from References 5.8.8 and 5.8.9 for rooms C13 and C20 are utilized.For the heating load analysis, only 50% of the heat loads from equipment is utilized for these rooms. The equipment heat loads total from Reference 5.8.8 and 5.8.9 for these rooms is the same as was used in the single unit operation only part of this calculation. This Appendix added by Revision 013.

Subject:

Cooling and Heating Load Analysis, Main Control Room HVAC Main Control Room (MCR) (755.0-C12) The methodology of this calculation treats the MCR as two separate but related spaces the division of which is demarcated by the suspended ceiling (See Section View B7-B7 of Reference 5.1.3). The lower 10 feet of the space is the MCR proper (i.e. the MCR), and the upper 7.75 feet is the MCR plenum. Previous revisions of this calculation accounted for all electrical heat loads, including lighting heat loads, to be located in the MCR proper. In reality, all of the lighting heat load originates and mostly remains in the MCR plenum. This is due to the fact that both the fluorescent and emergency incandescent lights are suspended about 18" above the suspended ceiling (Section View A3-A3 of Reference 5.1.16) with the suspended ceiling at El. 765.0 and the lights at approximately El. 766.5. This is possible due to the fact that the suspended ceiling is of a "luminous ceiling panel" type of suspended ceiling (Note 2 on Reference 5.1.2).Conditioned air is delivered directly to the lower MCR proper space by triangular duct and grilles (Section View C3-C3 of Reference 5.1.2) that are mounted flush with the suspended ceiling. The mixed and heated air in the MCR proper rises and enters the MCR plenum via natural convection. Little or no air should fall from the MCR plenum back into the MCR proper because the return ductwork and grilles are located in the MCR plenum. Therefore, most of the lighting heat load leaves the MCR plenum before ever having the chance to transfer to the MCR proper.This appendix will account for half of the MCR lighting heat loads to be in the MCR plenum. This is a deviation from the previous revision methodology and is not as conservative as the previous methodology but is still conservative since only a small fraction of the lighting heat actually transfers to below the suspended ceiling. Another deviation from the previous revision methodology is the treatment of transfer air from the Relay Room (755.0-C13). Per Section View D3-D3 of Reference 5.1.12, the wall penetration for fire damper 0-XFD-31-153 is above the MCR suspended ceiling.Therefore, the air is transferred to the MCR plenum instead of the MCR proper. This is conservative for the purposes of analyzing cooling loads because the air in 755.0-C 13 is demonstrated to be cooler than the air in either of the MCR spaces (i.e. the MCR proper will not have the benefit of cooling air from 755.0-C 13).UVA 4.2.1 states MCR electrical heat loads that are higher than those used by the single unit operation only part of this calculation. Even with half of the lighting load moved to the MCR plenum (27,016 Watts or 92,182 Btu/hr), the electrical heat load in the MCR proper is significantly higher than the value used in the single unit operation only part of this calculation (121,016 Watts or 413,000 Btu/hr vs. 316,241 Btu/hr for Normal conditions and 334,003 Btu/hr for LOCA conditions). For the heating load analysis, only 50% of the heat loads from equipment in the MCR is utilized. This amounts to about 160,000 Btu/hr. This value is lower (more conservative for heating load analysis) than the value (172,362 Btu/hr) used in the This Appendix added by Revision 013.

The required relative humidity levels are within the design limits for all rooms of concern. The Environmental Data Drawing for Corridor C3 (Ref. 5.3.4) should be revised to reflect a maximum Normal Operation room temperature of 94°F for Room 755.0-C3.For LOCA Operation cooling of the 755.0 elevation of the Control Building, all steady state room temperatures are at least slightly below the Maximum Design Room Temperatures for LOCA Operation conditions except for Corridor C3 which is almost a single degree Fahrenheit higher than its Maximum Design Room Temperature for LOCA Operating conditions. The Environmental Data Drawing for Corridor C3 (Ref. 5.3.4) should be revised to reflect a maximum LOCA Operation room temperature of 99°F for Room 755.0-C3.This Appendix added by Revision 013.

Subject:

Cooling and Heating Load Analysis, Main Control Room HVAC For Normal Operation heating of the 755.0 elevation of the Control Building, all rooms have steady state room temperatures that are lower then the Minimum Design Room Temperatures for Normal Operating conditions except for the Corridor C3 and the Locker Room & Showers.However, most of the rooms that do not have high enough steady state temperatures miss the minimum design temperature by less than a single degree Fahrenheit (MCR, Relay Room, and Corridor C15). This was generally the same results determined by past revisions of this calculation. Therefore, revision of the Minimum Design Room Temperatures for Normal Operation on the Environmental Data Drawings for the MCR, Relay Room, and Corridor C 15 is not required.The Mechanical Equipment Room C1 has a steady state temperature that is about 3.5°F below its Minimum Design Room Temperatures for Normal Operating heating conditions. This is essentially the same result that was determined in the corrected Single Unit Operation heating analysis performed in this revision. Therefore, the proposed revision of reference

5.3.7 discussed

in Section 9.4 is also applicable to Dual Unit Operation. The Mechanical Equipment Room Cl and Corridor C15 both have relative humidity levels higher than the design limit range for Normal Operating conditions during heating mode. The evaluation of high humidity levels is provided in Note 1 of Section 9.2 of the main body of the calculation. This evaluation applies to these two rooms.For LOCA Operation heating of the 755.0 elevation of the Control Building, all rooms have steady state room temperatures that are higher then the Minimum Design Room Temperatures for LOCA Operating conditions except for the Mechanical Equipment Room C 1. The Mechanical Equipment Room Cl has a steady state temperature that is about 3.5°F below its Minimum Design Room Temperatures for LOCA Operating heating conditions. Again, this is essentially the same result that was determined in the corrected Single Unit Operation heating analysis performed in this revision. Therefore, the proposed revision of reference

5.3.7 discussed

in Section 9.4 is also applicable to Dual Unit Operation. Conclusion Summary Results of this Appendix require that reference 5.3.4 be revised to reflect higher temperatures in Corridor C3 during cooling mode for both Normal and LOCA operation. The Maximum Design Room Temperatures should be raised by 1 degree Fahrenheit for Room 755.0-C3. This change is only applicable to Dual Unit Operation. Reference 5.3.4 is acceptable as is for Single Unit Operation Results of this Appendix concur with the requirement in Section 9.4 that reference 5.3.7 be revised to reflect lower temperatures in Room 755-Cl. Therefore, this change would be applicable to both Single and Dual Unit operation. This Appendix added by Revision 013.

Cooling and Heating Load Analysis, Main Control Room HVAC The total heat loads computed in this appendix do not challenge the capacities of the AHUs nor are the AHU return air temperatures above either the rated Entering Air Dry Bulb or Wet Bulb Temperatures from page 1 of Attachment C. However, since the steady state room temperatures of some rooms do slightly exceed their design limits, the MCR HVAC system as configured does not have excess capacity with regards to air flow (however, excess coil capacity is available). Therefore, a minimum air flow analysis like that performed in Appendices A and B is not performed in conjunction with Revision 013 of this calculation. This Appendix added by Revision 013.

Cooling and Heating Load Analysis, Main Control Room HVAC Appendix D -Evaluation of Relative Humidity in Main Control Room during Outside Abnormal Condition 1. Purpose This white paper is to determine the minimum and maximum relative humidity in Main Control Room (MCR) during the abnormal conditions. According to environmental drawing 2-47E235-36 Rev.0 (Ref.2.1), the maximum abnormal temperature is 102 OF with a specific humidity of 140 grain of moisture per pound of dry air (0.02 pound of moisture per pound dry air).2.

5.1 Minimum

Humidity According to System Operation instruction SOI-31.01 (Ref.2.6, Page 8), the MCR steam generator (humidifier) shall be in service any time the relative humidity in the MCR is <50% as indicated at the MCR AHUs. Humidity levels of less than 20% may affect function of touch screens and will affect operability of Unit 2 Common Q PAMS. If the relative humidity is less than 20%, instrumentation operability must be assessed. Therefore, the use of 20% as the minimum relative humidity in MCR is reasonable.

5.2 Maximum

Humidity Considering that the HVAC system for MCR is safety-related system, the air condition unit will continue to operate during outside abnormal conditions. During the abnormal condition, the entering temperature and humidity ratio to the cooling coil can be calculated as follows: Te = [(QreturnxTreturn)+(QoutsidexToutside)](Qreturn+Qoutside) Te = [(32403 cfm x 77.1 °F)+(3597 cfm x 102 °F)]/(32403 cfm + 3597 cfm) = 79.6 OF, less than 87.8 OF (Vendor data, Ref.2.2)We = [(QreturnxWreturn)+(QoutsidexWoutside)]/(Qreturn+Qoutside) We = [(32403 cfm x 0.0085 pound of moisture per pound dry air) + (3597 cfm x0.02 pound of moisture per pound dry air)Y(32403 cfm + 3597 cfm) = 0.0096 pound of moisture per pound dry air According to Psychometric Chart (Ref.2.4), the wet bulb temperature is 64.5 OF, which is less than 65.4 0 F (Vendor data, Ref.2.2)Since the calculated entering dry and wet bulb temperatures to cooling coil are less than those entering temperatures listed in vendor data, the leaving temperatures and specific humidity from coil are still conservative and the supply air temperature and specific humidity ratio to MCR spaces stay the same. According to Calculation EPMLCP072489 This Appendix added by Revision 014. Appendix D Document: EPMLCP072489 I Rev.: 014 1 Plant: WBN / Units 1,2 I Page: 3 of 3

Subject:

Cooling and Heating Load Analysis, Main Control Room HVAC Rev.13 (Ref.2.3), the air temperature and relative humidity for MCR during the abnormal condition stay the same as those in normal condition, which are 78.1OF and 41% RH, respectively.

6.0 Conclusion

Based on the above analysis, the temperature and relative humidity in MCR still remains as 78.1OF and 41% RH during outside abnormal condition. As shown in Figure 2, the condition in MCR will remain within the range of block 1 (Air Conditioning -Normal) during outside abnormal condition with maximum temperature.

Description:

NRC INFORMATION NOTICE 92-32 PROBLEMS IDENTIFIED WITH EMERGENCY VENTILATION SYSTEMS FOR NEAR-SITE (WITHIN 10 MILES)EMERGENCY OPERATIONS FACILITIES AND TECHNICAL SUPPORT CENTERS -SYSTEM 31 This response is a supplement to the response provided by Technical Support and addresses the design parameters of the HVAC system for the TSC. It also evaluates the adequacy of TSC HVAC system to maintain habitability with 40 people in the TSC area.The environment of the TSC area is controlled by the Main Control Room (MCR) HVAC system. Since this system is a safety related system, the maintenance and test criteria have already been established and are in place. There should be no problems like those identified in IEN 92-032.The subject IEN suggested that 70 people would be a more appropriate number to use in determining the cooling load in the TSC area. It also proposed that the heat load for each person should be 640 BTU/hr instead of 450 BTU/hr.During the investigation of this problem the design basis calculation for the MCR HVAC system, EPM-LCP-072489 RI, was reviewed to identify the design parameters used to determine the adequacy of the system. The calculation is based on 25 people in the TSC, 2 people in the NRC Office and 4 people in the Conference Room. Bill Peggram of Watts Bar Nuclear Plant's Emergency Preparedness Group estimated that there could be as many as 40 people in these three rooms after a Design Basis Accident (DBA). This number is based on exercises conducted at Sequoyah Nuclear Plant and includes up to five people representing the NRC.The existing heat load in the calculation is 450 BTU/hr.This rate is based on the heat produced by a mixed group of males and females "seated, light work, typing" per the 1985 ASHRAE Handbook, page 26.21 Table 18. If all the people are male and the activity is defined as "standing, light work or walking slowly" a more appropriate heat load for each person is 640 BTU/hr. This is broken down into 315 BTU/hr sensible heat and 325 BTU/hr latent heat per person.Calculation EPM-LCP-072489 is being revised as part of the Mechanical Reverification Program and will include 40 people in the TSC area at the 640 BTU/hr load per person. This change has been coordinated with the SERT team leader. A review of this calculation confirms that there is sufficient margin in the cooling capacity of the existing MCR HVAC system to maintain a habitable environment in the MCR and the TSC area with these changes.

Description:

Problems identified with Emergency Ventilation Systems for Near-Site Emergency Operations Facilities and TSC. Called Rick Saputa (Licensing, ext -3828), he says I do not need t6 address those items which deal with the Emergency Operations Facility (EOF).At WBN the Technical Support Center (TSC) is located inside of the Main Control Room Pressure Enclosure, elevation 755 in the Control Building. The TSC is cooled/ventilated by the same system which supports the Main Control Room. This Safety Related ventilation system is required by Tech Specs. The portion of this ventilation system which is dedicated to the TSC was originally designed to support 25 people at 250 BTU/Hr (latent) and 250 BTU/Hr (sensible) per person. Reference Calc EPM LCP 072489, ALSO Revision 1 B26910419215. Bill Peggram (Emergency Preparedness Section) says that no more than 40 people will be in the TSC area which includes the NRC office and the conference room.On 07/14/92 discussed this NER item with Don Sokol (Site Engineering). He is confident that the existing system is adequate to support 45 people located in the TSC area which includes the NRC office and the conference room. He makes this statement based on 250 BTU/Hr (latent) and 250 BTU/Hr (sensible) per person. This reflects approximately the same 640 BTU/Hr per person as referenced in NRC Information Notice 92-32. This determination based on the 1985 ASHRAE Handbook, page 26.21, Table 18 (Rates of Heat Gain from Occupants of Conditioned Spaces).Based on the above information, WBN does not have similar conditions as those identified by IE Notice 92-032.

The. air. on the other side of the wail/roof was at :he sol-air temper-atures listed in Table I of the ASH-R.4E Handbook and thus varied with time. In some runs, higher. sol-ai: temperatures were also used. In-side and outside air film heat-transfer coefficients were varied in the range that may be expected in practice. The heat :ransferred from the wall to the room air was calcu-lated at each instant; the CLTD at each instant was then calculated using Equation 1. Computer runs were continued until calculated ICLTDs were repeated in 24-hr cy-'c.es.In Table l.. a summary of some typical calculations for walls and roofs is presented. The mean sol-air teMp eratures and mean CLTD s are 24-hr mean values. hi and h. are in-side and outside air film heat-transfer coefficients, respectively. In Table 2, the calculated CLTD s for various horizontal roofs are listed. All of these.are for dark roofs and the sol-air temperatures listed in Table I in the ASHRAE Handbook. Note that all CLTDs listed in the Handbook for various roofs and walls were also calculated using the sol-air temperatures from this source.All calculations were done for heavyweight concrete of 140 lb per cu .ft density.. The insulation con-sidered had a density of 15 lb per cu ft, thermal conductivity of 0.024 Btuh per ft per deg F, and specific heatof 0.17 Btu per lb per deg F.Results The results listed in Table 1 show that: Mean CLTD = Mean room temperature and outside ai: Sa , 2 temperatures. where -sal-air Calculation procedure J temoerature For heavyweight concrete wails 2 h ickc=room air ft thick or thicker. with or witnou: temperature insulation. use the followin 'Thus, the 24-hr mean heat Yain corrected CLTDs (in accordance /can be calculated with Equation I with Footnote ' of Tabie : n using the rean Cr TD from Eoua- ASHR!AE Handbook): N. 11: N7.tion 21. 7;E .1711; S- .1 ',- S .1 -'7.
