SUMMARY
OF RESULTS:
- 1. The installed chiller capacity of 450 tons per train is sufficient to maintain adequate chilled water return temperatures during the worst case transient conditions following LOCA. The worst case transient occurs immediately after the Air Handling Units are actuated on a Safety Injection signal, assuming all rooms served by air handling ,
units are initially at the design temperature, the EAB is the lineup resulting in maximum return air temperatures, and the control room envelope are at its maximum temperature. The maximum load occurs on Train C. The maximum load as a function of chilled water supply temperature is: l i TRAIN C CHILLER LOAD, TONS CHILL WATER SUPPLY TEMPERATURE

- 2. The chilled water system can meet required safety functional !
requirements with only the 300 ton essential chiller , operable in one or more operable train (s). There are limits on room temperatures and system operation which must be met in this case:
. ECW flow will be secured through any non operable 150 ton essential chiller. This is required because heat j can be transferred from the ECW to chilled water through the' idle chiller (by natural convention of the !
refrigerate) if flow is maintained on both sides. ,
- Any non operable 150 ton essential chiller in an .
operable chilled water train will be locked out ) electrically. J Chilled flow will be maintained through the D2D ' operable 150 ton chiller in an operable chilled water ; j train. This lineup is adopted to avoid disturbing the L} flow balance of the chilled water system. (The j advantages of increased chilled water flow through the
- j 1
300 ton chiller have not been fully explored. This lineup may be changed in the future.) i
. The chilled water temperature control of the operable :
300 ton chiller must be set to control at 48 *F ( i 1 >
*F ) at maximum chiller load. This will result in a chilled water supply temperature of about 52 *F after !
4 l mixing with the flow through the idle 150 ton chiller.
' This will maintain reasonable EAB temperatures without ;
l requiring throttling of chilled water.
+ The temperature control loops for the EAB cooling coils j
must be defaulted to the accident condition. This is ! necessary to eliminate the transient load caused by , diverting full flow through the coils on an SI signal. l The outlet air of the cooling coils will be kept reasonably close to the design value by the higher i chilled water temperature. h e i 4 I l

SYSTEM DESCRIPTION: i The EAB has three 50% fan / cooling trains and three major air distribution headers which correspond' closely to the power trains. However, the fan / cooling trains do not match exactly A limited amount of mixing i with the air distribution systems. between trains occurs as a consequence of the air distribution duct work. This mixing and resulting air temperatures affect the cooling load on each train. While the system was designed for only 2 fan / cooling trains operating, a Safety Injection signal will start all 3 trains. Thirty minutes is assumed for operator action to restore the normal lineup and/or respond to a single failure. With one fan / cooling train not operating, the heat load from the associated distribution header is shared by the remaining trains, but not equally. Due to the number of combinations it was necessary to model the EAB air flow in a simple spreadsheet. Those single failures which result in 2 fan trains running are accurately modeled using flow rates measured during the final air balance for each Unit. Flow rates in the t case with 3 fan trains running (failure of a chilled water train) are estimated using the fan curves and system resistances implied from the air balance data. The Control Room Envelope also has 3 50% fan / cooling trains, however, the air distribution system has a common supply and return duct. Two of the three single' failures result in 3 fan trains running (for the 30 minutes allowed for operator action). Air flow rates are estimated for these cases using fan curves and implied system resistances. Actual flow rates recorded during final air balancing are used for the single failure of a SI train. The single failure of one Control Room fan train is clearly not a limiting case regarding chiller capacity. A variety of individual air handling units served by the essential chilled water system provide safety related cooling in rooms normally served by the non-safety related MAB or FHB ventilation system. Most of these air handling units are started. by a Safety Injection signal. The Radwaste Control Room (MAB 217) air handling units are served by the essential chilled water system even though this room contains no safety related i equipment. . l The control of chilled water outlet temperature functions as a l proportional controller.

The proportional band can be adjusted between 0 & 10 *F. (Ref. 57} , B. HISTORICAL PERSPECTIVE The calculations of building and room heat loads for areas cooled by the essential chilled water system, performed for original ; design purposes, vere highly conservative. Electrical and I & C calculations of heat losses from lighting, cables, electrical equipment, control panels, etc., used conservative methods and/or conservative vendor data. In some cases arbitrary margins were added (i.e. for cable tray losses) for future additions or additional conservatism. Calculations for mechanical components frequently used the rated motor horsepower instead of the actual brake horsepower required by the component, and added arbitrary , margin to piping heat losses. An additional margin was added to the total heat load. The result ensured the chilled water system would not be undersized. This was appropriate for original design purposes. However, actual chiller loads experienced in normal operation are only a fraction of the calculated normal chiller loads. If post accident heat loads are conservative to a similar degree, then perhaps the 300 ton essential chillers are sufficient to meet ; post accident requirements. In addition to conservative methods to obtain room heat loads, the original design calculation took combinations of events which were mutually exclusive. For example, emergency heat loads were calculated assuming no non-safety HVAC systems were operating, but no non-class lE heat loads were lost. The original design calculations also included several non- i conservative methods or assumptions. These included not accounting for the inexact match between EAB HVAC Trains and the , train related air distribution headers, not analyzing single I failures other than loss of one Safety Injection train, not accounting for heat added by the chilled water pump, not , accounting for latent heat loads in rooms in the Fuel Handling i Building, not considering the transient affects of diverting full chill water flow through the EAB and Control Room coils, and not considering actual cooling coil performance when calculating EAB
& Control Room latent heat loads.
Since the calculated normal and post accident heat loads in the 1 original design calculations were so much higher than actual ; loads, the capability of the system to meet minimum chiller loads j 1 I l

SUMMARY
OF METHODS Steady state heat loads were calculated for two scenarios, and the range of applicable single failures. P The initiating events studied in this analysis are Loss of and Coolant Accident (LOCA) withoutLOOP, LOCA without Loss of Off-Site where Power normal (LOOP) operating loads LOCA with LOOP. not tripped by SI signal or lost as a consequence of the LOCA conditions are assumed to continue to operate, is the limiting event with respect to maximum steady state chiller load. In the LOCA with loss of non-class 1E power, only components with diesel or battery backed power are assumed to operate (and generate heat). Conditions are assumed consistent with LOCA, , soon after initiating recirculation from the RCB emergency sump, and before operator action is taken to shed unnecessary loads. In the LOCA without loss of non-class lE power case, conditions i are assumed consistent with LOCA, soon after initiating recirculation from the RCB emergency sump, and before operator action is taken to shed unnecessary loads. Normal lighting and other non-safety related equipment is assumed to continue to operate (and generate heat). ; The single failures which affect area heat loads and/or heat , removal capacity are 1) loss of one EAB supply fan, 2) loss of one chilled water train, and 3) loss of one Safety Injection system train. It is not obvious a priori which of these single > failures is limiting. The steady state heat load is useful in providing insight into effects of single failures but does not represent a condition which is actually expected to occur. The thermal lag of the i building structure insures that transient conditions will dominate the heat load past the time that operators would have ' secured unnecessary equipment. The dynamic effects which are non-conservative and which therefore must be considered are: l j
+ The room temperature with the air handling unit running will be lower than design, and lower than the normal temperature in many cases. The AHU will be removing more heat than the room heat loads until equilibrium is achieved.

The l rate of heat removal immediately after the AHU is started is i higher than the steady state room load, in some cases,much higher. .
. The Control Room and EAB cooling coil outlet temperature is '
controlled by temperature control valves which control chilled water flow through the coils during normal operation. A safety injection signal diverts full chilled. j water flow through the coil. This will immediately increase the heat removal through the coil.

The chiller will remove heat up to its maximum l

SUMMARY
OF SPREADSHEETS: ' t The QUATTROPRO spreadsheets in Appendices B and C (and attached , computer files A:\B and A:\C) were used to determine actual i cooling coil performance for the actual air flow rates (from l Final Air Balance test results) for Units 1 and 2 respectively. Design water flow rates and other coil data were taken from coil } data sheets listed in Reference 32. Methods and equations are j explained in Appendix A. The coil thermal effectiveness "THEFF" l is calculated for use in other. spreadsheets. i i The QUATTROPRO spreadsheet in Appendix D uses the' same heat i transfer model as B & C, using the design specifications for each ! coil. In virtually every case the calculation model predicts a ! I higher thermal effectiveness "THEFF" than the ' design specification requires ("EFFSPEC"). For those coils purchased ! for the current conditions, this is the expected result of ; selecting an available vendor model to meet or exceed specified conditions. Several of the coils were originally purchased for l much different conditions than the current design specifications f reflect, and in some of these cases the coil capability calculated herein is much greater than the design specification , indicates. The higher thermal effectiveness calculated by this calculation lLs conservative for purposes of determining maximum chiller loads. This is evident particularly in the transient j analysis of room Air Handling Units, wherein the maximum load is directly proportional to thermal effectiveness. A higher thermal i ( effectiveness is not conservative in the portion of this ,

- 1. EAB HVAC MODEL The EAB HVAC system is shown schematically in Figure A1. The air flow rates measured during final air balance testing at selected points are shown in Appendix H. The flow in the air handling unit train could not be measured during final air balancing, so
- the flows were assumed to be equally split between trains. This is also assumed in this calculation. The small variation in header flows between different fan lineups indicates fan train performance does not vary significantly between trains.
The input data required for each case includes identification of which EAB fan trains, chilled water trains, and safety injection . trains are in operation; air flow rates in the train supply ducts ! and train battery supply ducts from Appendix H; heat loads added by EAB supply and return fans from Appendix F; and thermal ( effectiveness of the EAB coils at the' actual air flow rate. I Each coil starts with an initial trial EAB coil outlet temperature of about 58 *F for each train, and the spreadsheet : calculates a coil outlet temperature. If chilled water supply temperature is below 52 *F, the calculated outlet temperature will be below 58 *F, and the calculated EAB load higher than the load calculated at the final iteration. For the single failure of one train of chilled water, the affected EAB coil outlet and return header are set at temperatures determined by hand l calculation. Some of the hotter air mixes with the adjacent train, increasing supply and/or return air temperatures in that , train, and thus increasing the heat removed by the coil in the ! adjacent train. The operable trains are iterated until the calculated temperature equals the trial temperature. This < converges after several iterations. l Failure of a set of EAB fans or failure of an entire Safety Injection train (i.e. failure of the initiation signal) resultIfin one of the tested configurations during air balance testing. , all 3 trains of fans are running, as in the case of failure of a chilled water train, then header flows and battery room i ventilation flows are estimated using fan curves and air balance data.

- 2. CONTROL ROOM ENVELOPE MODEL The Control Room Envelope HVAC system has a common supply and return header, so the temperature to and from the distribution system does not depend of the combination of fans running. The recirculation and makeup flow rates are based on final air balance data for the case of failure of one Safety Injection The other two train, which results in two fan trains running.
single failures result in three trains of fans running until operator action is taken to stop the unnecessary fans. . The input data identifies which fan trains are running; whether or not the system is in the Recirculation Mode (this is for future use, no recirc. case is included in this calculation); makeup, cleanup, and return air flow rates; and heat loads to air stream and room for all fans. This Data data is taken from final air for the third fan is taken balance for the two fan case. from another mode of the final air balance. Flow rates and fan heat loads are adjusted based on fan curves for the three fan Cases. (
- 3. MODELS OF ROOMS WITH AIR HANDLING UNITS i Several rooms combine ventilation flow with one totalorroom two cooling air handling units with cooling coils. Thus the load is shared between two or more items. We are interested in l the load to the essential chilled water system. The method of determining the load to the chilled water system is demonstrated using the CCW/ ESSENTIAL CHILLER rooms as an example.
The CCW/ ESSENTIAL CHILLER rooms each contain two air handling The : units, one cooled by ECW and one cooled by Chilled Water. heat load taken by each cooler depends on the room temperature, As a ECW inlet temperature and Chilled Water inlet temperature. each further complication, if normal MAB HVAC flow is not lost, room has a significant ventilation flow. In the case of LOCA without loss of non-essential power, most of the rooms with air handling units receive significant ventilation flows. These rooms are handled in the same manner. (
