Assum tions 4,1 High temperatures may develop in. the battery rooms if'a SBO event occurs during hot weather. The loss of HVAC due to SBO can result in a temperature rise in the battery rooms to 107'F according to Ref. 3.8. This temperature increase will not degrade the. battery capacity (see Ref.
3.3) or result in any anomalaus battery performance in either the charge or discharge mode of operation. Certain authors (Ref. 3.9) recommend. maintaining operating battery temperatures below 110 F. Xt is therefore assumed that no battery capacity degradation occurs at the high temperature limit of this event.
4.2 The battery chargers and inverters are designed to operate in the temperature range -10'C to 40 C (14 F TO 104'F)
(see Refs. 3.6 and 3.7). The peak temperature of 107'F is above this design range hut is acceptable under the requirements of Ref. 3.2. Zt is shown in this analysis however that the heat capacity of the batteries, which was not accounted for in Ref. 3.8, significantly moderates battery room temperature transients. The lower extreme of the ambient temperature design range for the chargers and inverters is well belaw the lawest temperature that would occur in the battery room in an SBO according to this analysis. Xt is therefore assumed that ambient temperature will not prevent or degrade battery charger function as designed at the end, of the four hour SBO, or inverter function during the entire period of the event.
4.3 The vital battery load during the SBG is specified in Ref.
3.1. See Sections 1.4 and 7.2 for SBO details.
4.4 Heating for the battery rooms was installed in 1987.
Prior to this time the heat sources in the rooms were the battery chazgers, inverters, and. lights. The battery rooms, with the air handling zoom, make up the lowest level of the Control. Building. This'.space has exterior walls on. three sides and. the floor which are below grade.
The Turbine Building is on the fourth side. The Relay Room is on the floor above. Ref. 3.4 shows this arrangement. A thermal madel for this space is developed which consists of the battery room air, the batteries, and the exterior walls and floor. Heat transfer from the air to the hattezies, walls, and flaor is by natural convection. Heat transfer through the walls and floor to exterior soil is hy conduction.
4.5 The battery room temperature control system is designed. to maintain temperature at 75'F + 2 F. For the low sign Analysis Revision 0 Page 2 re 3341 Date 11/30/90
temperature SBO transients the initial temperature is assumed to be 73 F.
- 4. 6' search of surveillance records showed that the lowest battery room temperature documented prior to the installation of heating was 60'F. Using this steady state temperature and the heat sources available (no external heat) it is'ossible to estimate the effective exterior ambient soil temperature (34 F). This calculation is shown in Section 6. Material thermal properties for air, water, and concrete were obtained from Ref. 3.10.
4.7 Battery charger efficiency is assumed to be 90 percent (Ref. 3.7). Under normal operating conditions with the chargers supplying 100 amps (normal) this will result in approximately 1200 watts of heat dissipated into the room.
The chargers do not function during SBO.
4.8 Inverter efficiency is assumed to be 80 per cent (Ref.
3.6). The inverters operate close to their rating (7.5 KVA) normally. This results in approximately ts of dissipated heat. The inverters function de ng O.
4.9 There are 6, 40 watt fluorescent light units in A battery room and 8, 40-watt units in B battery room. Xt will be assumed. that about 300 watts of heat is due to lighting.
This lighting is lost during SBO.

- 11.9 = 61 14F 6.1. 6 Computer Code Development A FORTRAN program was written, using the state equations from Section 6.1.2. The difference equations were developed using the modified Euler-Gauss method. which provides reasonable ((10~) accuracy for this type of calculation. The source code for this program is given in Appendix 1.
6.2 Battery Capacity Evaluation 6.2.1 The effect of battery room caoldown during SBO on battery capacity is evaluated using the methads developed for battery sizing analyses (Ref.. 3.1) and. electrolyte temperature correction factars (Ref. 3.3). The temperature correction factors are used to madify (increase) the actual battery load ta create a temperature corrected, load.. These connected loads are then used. in the battery sizing analysis.
6.2.2 s.n order to simplify battery capacity calculations, cooling is modeled as a step function. Xt is assumed. that temperature daes not change during the first hour of the SBO, and then drops to a lower, constant value, for the last three hours. The value of the final temperature is lowered until the battery capacity is exceeded. This is then considered. to be the limiting temperature for operation. The conservatism of this approach is evaluated by comparing the "step" temperature model with the continuous temperature drop data from the thermal analysis.
6.2.3 The battery capacity calculation is performed. using the Load Change Report Spreadsheet. This program is written in the Symphony environment and is maintained: in the Electrical Engineering Central File. The primary use of esign Analysis Revision 0 Page 8 ERR 3341 Date 11/30/90

7.0 Results 7.1 Tables 1, 2, and, 3 show the temperature of battery room air, battery cells, and exterior walls. during one minute, ten minute, and five hour periads after initiation af Station Blackout. The battery temperature after four hours is about 71.&'F.
7.2 The temperature correction factar fram Ref. 3.3 for 71.8 is ahaut 1.034. The battery sizing analyses yield maximum cell "B" size correction factars of 1.64 and. 1.10 for the "A" and. batteries respectively (see Ref. 3.'1). Since bath of these results exceed the required temperature correction of 1.034, it is concluded. that the battery capacity meets the SBO 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> caping requirement. The cell sizing calculations are shawn in. Tables A5A and BSA.
7.3 The transient thermal respanse of the battery room environment predicted hy this analysis is significantly slower than the predicted in. Ref. 3.8. Since Ref. 3.8 acMresses loss of HVAC and resulting heating ia. hat weather, the results do not directly conflict with those presented here. Hawever applicatian. of the heat transfer model used. in this analysis, to the heatup problem results in a much slower, response.
7.4 Although outside the formal. scope of this analysis, the model developed. here is applied. to battery room heat up for the case in which external soil temperature is. 75 F and the initial steady state battery raom temperature is 75'F. Both SBO and loss of offsite power are considered.
Although refinements to the model would increase the accuracy, the physical processes which cantrol the temperature transient aze made cleaz. The battery raom temperature remains below 90'F in either case (Tables 4-9).

To give the users the orocedure and documentation reouirepents for using the Load Change Report Spreadsheet. This spreadsheet calculates the reouired cell size of Ginna S".ation Vital battery 8 based on present loads. Syaphonv version 2.0 gas used to perform the calculations. The Svaohony file is LCR 81B ~ MRl.
PROCEDURE'.
Load Svaohonv, then retrieve LCR BIB. Enter eacn load addition or deletion as a separate line iten on page 2. using the referenced Electrical Load Change (ELC) form as the source docuaent. Attach ail referenced ELC fores to this report.
".. To obtain the hard copies of Load Change Reoort pages 1. ". and 3. ;old doun the ALT kev while striy, ng tne P key. ..'.: updated report ui!l be autooaticallv saved. Next, :he screen vill shou the form in the Alluays Application. Hit F19. select P for orint, ano G for go.
- 3. To exit Alluavs. hit F10. select ". to cuit. After it has returned :o Svaohonv, exit Symphony. The Svaonony Access Svstem menu snould apoear on the screen.
?'.esse keep in mind, ALT-P can onlv be used once. .'he user vishes :- get another printout. he aust use ALT-N instead of ALT-PE because the Alluavs Aoolication need onlv te sttacneo ores. ALT-N vi I} ." nc:icr. the same as ALT-P except . 'on t .tach Allvays
