PURPOSE The design basis for cooling the Electrical Penetration room 5

containing Essential Electrical equipment during a LOCA event uses Essentials Air Cooling Units (ACU) and the Essential Chilled Water System (ECWS) for cooling. In the event that either the ACU or ECWS fails during a LOCA, the room temperature will rise rapidly.

10 The purpose of this study is to determine the transient air

'I 2 temperature for 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months in the limiting case for the two 13 Electrical Penetration rooms containing Essential equipment and 14 receiving Essential Cooling. Transient response within the first 98 minutes is of primary concern to support ANPP's program to respond to EER 88-EC-818.

17

'I 8 Standard room heat-up (RMHTUP) comput: er program, ME284, Rev. Al 19 is used to study the room ambient air heat-up by the equipment 20 in the East Electrical Penetration room located on the Aux.

21 188'levation. This room contains "B" safety train 22 equ ipment.

23 24 The heat generated in the, room is transf erred to the room air f 25 stored in the room enclosure concrete (heat sink), and 26 transferred to the air outside the room. The transient

, 27 temperature for the room air is studied for a time period of 24 28 hours3.240741e-4 days 0.00778 hours 4.62963e-5 weeks 1.0654e-5 months without any HVAC.

1. The initial temperature inside the Electrical Penetration 0

room is 92 F. This is based on the actual measurements made by ANPP in the operating unit (Ref. 28).

2. The initial temperature outside the Electrical Penetration room 0 is 92 F. This is based on actual measurements made by 10 ANPP in the operating unit (Ref . 28) .

12

3. Neither essential chilled water or normal HVAC is available 13 during time period of this study. This is the principle failure assumed at the onset of this study as discussed in section I.

16 17 4. Initially, steady state temperature conditions exist in the 18 Electrical Penetration Room and outside the rooms.'.

19 20 With the exception of the containment building interface, 21 the walls, ceiling, and floor are used for a heat sink.

22 All heat sinks will be modeled using a thickness equal to 23 one half the thickness of the floor slab. This value is less than the actual thickness of the thinnest wall or ceiling boundary of the considered room. Use of only one 26 half the thickness of'he floor slab as a heat sink for the 27 Electrical Penetration room is based on the consideration 28 that the Mechanical Penetration room directly below is 29 heating rapidly during the IOCA event.

30 31 Experience with results of the RMHTUP computer runs suggest that for short time periods (i.e. 98 minutes), heating from 34 36

Because heating from below is demonstrated to have negligible effect on the upper half of the floor thickness during the time period of interest, (98 minutes), this 10 portion of the floor slab is available to act as a heat sink for the 188'levation Electrical Penetration room.

12 With time, loss of this slab as a heat sink is expected/

13 and actual 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months room temperatures are likely to be 14 somewhat higher than the model predicts.

Use of this value for the thickness for the entire boundary 17 does not affect the short time (98 minute) accuracy of this 18 study. As can be seen by review of the computer output/

19 heat generated within the room does not have sufficient 20 time to penetrate and thereby utilize the full heat capacity of thicker heat sinks.

22

6. /he Containment Building wall which interfaces with the 24 Electrical Penetration rooms is 4 ft thick concrete.

25 Because the containment building is normally operating at 26 approximately 128 0 F, this wall is actually a small heat 27 source during the initial phase of room heat up based on an 28 initial Penetration room temperature of 92 F and is 29 reflected as such in the heat load tabulation.

30 31 In the longer term, (24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ), it is expected that this wall will become a larger heat source because internal 34 35 36

U containment heat generated by the initiating LOCA event has had time to penetrate the containment wall. Because the focus of this calculation is for short term results, (98 minutes), long term heat gain from the LOCA within containment is not considered. The validity of this assumption is evident from Figure 7-5 of Topical Report BC-TOP-5-A, Prestressed Concrete Nuclear Reactor Containment Structures (Ref. 22). Figure 7-5 is a plot of 10 temperature distribution across the containment vessel wall for varying times after a Design Basis Accident.

12 After the longest period shown, 182 minutes, heat resulting 13 from the D.B.A.-has penetrated approximately 12 inches into-the thick concrete containment wall.

16 The heat generated within the room is considered as being

'17 constant.

18 19 8. The dimensions of the Electrical Penetration rooms for all 20 three units are essentially identical. In addition, the 21 equipment and lighting are virtually the same for all of 22 these rooms. This study is performed for the Electrical 23 Penetration rooms in Unit 1 and is applicable to the 24 Electrical Penetration rooms in all three units.

25 26 9. Per assumption 3 above, the Essential Chilled Water is not 27 available during the time period of this study. For a 28 conservative approach, the ACU fan will be assumed running 29 without chilled water through the essential coils. 81%

30 efficiency of the ACU fan motor is assumed for calculation 31 room heat load. This is a typical motor efficiency for 3 hp motors as shown in reference 14, chapter 22, table 38, page 417.

ll. The room walls are requ ired to be divided into a number of layers for computation of temperature distribution in the 10 concrete walls by the computer model.'he required input for the thickness of the first layer and the multiplication 12 factor for thickness of other layers are selected as 8.81 ft (approximately 1/8") and 1.41 respectively.

16 18 A. Density 144 lbs/f t 3 (Ref 16) 19 B. Thermal conductivity 8.54 (Ref 16) 20 C. Specif ic heat 8.2 .btu/lb- P (Ref 16) 21 22

13. Gaps occurring between penetration room walls and the containment building are closed and sealed by flashing as 24 shown on references 24 and 25.

25 26 14. Personnel and equipment doors are considered massless and 27 perfect insulators, therefore non-contributory toward a heat sink.

30 15. Room volumes do not exclude installed hardware such as 31 electrical cabinets panels, and switchgear. Sensitivity runs indicate that the room heat up time vs. temperature plots are not sensitive to changes of net room volume as much as 18% (Ref 23).

After longer times, it is 27 likely that temperatures will be higher than these results indicate. Loss of the East Penetration room floor as a heat 28 sink in the long term is likely due to anticipated high 29 30 temperatures building up in the Mechanical Penetration room 3 'I below.

A. Model

Description:

The room heat-up computer program, RMHTUP, program number ME284, version Al, can be used to study the room ambient air heat-up by the equipment heat or any other. heat sources in the room.

10 The temperature of room ambient air increases with time, 2

due to the heat released from the equipment and other 13 sources. The heat generated within the room is transferred Ia to the ambient room air, stored in the room enclosure (walls, ceiling, and floor) and transf erred to the air outside the room.

'17 18 The room walls are divided into a number of layers with

'I 9 incremental thicknesses for numerical computation by the 20 computer program. In this study, the value of imaginary 21 thickness of first layer of concrete wall is selected as 22 8.81 ft and the multiplication factor of imaginary 23 thickness of other layers is taken as 1.41. In other words 2a the first concrete layer thickness is 8.81 ft (approx.

25 1/8"), the second layer thickness is 8.8141 ft (approx.

26 3/16"), third layer 8.81 X (1.41) ft, etc.

27 28 The transient room temperature is determined from the heat 29 balance equation, which balances the heat generated within 30 the room and the heat transf erred to the ambient room air, 31 stored in the room enclosure and transferred to the outside air, as shown below:

VINGT Results The transient temperature for the Train "B" Electrical Penetration Room air obtained from the computer output, is shown in Figure 1. The transient temperature output, Appendix A, shows that without any normal HVAC or Essential Chilled water and with the door closed, the calculated temperature in the pump room will be as follows:

10 Time Period Temper atu re 0 F 12 8 min 92.88 13 2 min 94.66 4 min 96.58 12 min 99.78 16 36 min 181.47 68 min 182.21

'IS 84 min 182.78 19 96 min 183.83 20 2 hr 183.49 21 4 hr 185.25 22 6 hr 186.58 23 8 hr 187.78 2d 12 hr 189.58 25 24 hr 113.88 26 27 Computer program input has been selected .to best model the 28 29 initial 98 minutes of room heat up. After longer times, it 30 is likely that temperatures will be higher than these 31 results indicate. Doss of the East Penetration room floor as a heat sink in the long term is likely due to anticipated high temperatures building up in the Mechanical 3d Penetration room below. See assumption 5.
