This maximum limit also assures that single l failure criteria are met. I 2.0 SCOPE The scope of this Engineering Analysis is to: 2.1 Define the worst case load and load profile. 2.2 Establish the engine / generator outputs based on the outdoor ambient a l temperature, diesel generator operational effects on room ambient BA temperature, results of radiator cleaning and re:;ults of engine coolant changeout. 2.3 Establish the capability of the generator / exciter to operate in the l diesel generator room environment based on the exciter cooling ' modification, MR-FC-90-073, as well as with the cabinet doors off in the event of cooler failure. 2.4 Establish the margin available to allow operator restart of l equipment to enhance shutdown, i.e. an air compressor. , 2.5 Determine maximum ambient temperatures for which the DG's are 4 operable. 110'F has been established as a goal for diesel ambient !
. air operating limits, based on review of meteorological data for i i

l OFFICIAL we r l l EA-FC-90-062 Rev. 2 Page No. 14 eas. ; f _ I k: t . p is complete within approximately 60 seconds and will not be considered here. 5.2 Station Blackout analysis requires that the loss of offsite power and diesel generator onsite power must be assumed. This Design Basis Event (DBE) is outside the bounds of this EA. 5.3 Limitorque motor operated valves are not considered long term loads. Cycling time is insignificant compared to long term loads. 5.4 For radiator performance analysis, a design jacket water flow of 1100 gpm (minimum) is assumed for all cases. This flow rate is the 6 discharge capacity of the engine water pumps per EMD and has been confirmed by test during full coolant flow operation. 5.5 For radiator performance analysis, Young Radiator Company utilizes uniform air velocities measured immediately downstream of radiator core to determine required SCFM for heat removal at various temperatures. All air velocities (converted to flows) obtained during FCS diesel tests were measured at the closest convenient point downstream of the radiator core. Due to flow restrictions present in system, the actual core face velocities would not be uniform, but the overall radiator capability would not be i significantly degraded. 5.6 At elevated ambient temperatures (>95'F), it is assumed that inlet air to the radiator fan is the same temperature as outdoor ambient. This assumption based on test data taken 7/17/90, per Reference 4.11, Attachment 8.11, page 9 and 10 of 15. 5.7 Instrument uncertainties from past data collection will be utilized in the turbo charger inlet air and JW analyses and heat-up rate projections and are considered conservative. See Reference 4.3 and 4.8. 6.0 ANALYSIS This analysis will establish the temperature limits at which the a engine / generator can operate the worst case safety-related loads in response 1 to a Design Basis Accident with a loss of offsite power. To accomplish this, accident loading will be compared to elevated ambient air temperature i engine performance determined by analysis of the expected DG cooling system i performance and test data to project DG room temperature rise above outside ambient air. .The analysis also demonstrates that the static exciter and generator can operate at the analyzed higher temperatures. l l

'The-analysis is organized to:
- 1. Determine the Worst Case accident load and peak load on the diesel generator.
- 2. Define the Test Data Reduction Criteria for use in the analysis.
- 3. Define the Engine / Generator Power Output criteria.
- 4. Define the engine, exciter and Generator Derating Methodology.
- 5. Define Test Data Instrument uncertainty for use in this analysis.

6.1 Worst Case Load and Load Profile , l The Fort Calhoun Station is required to have sufficient onsite i electrical generation capacity to safely shutdown the reactor and j maintain it in a safe shutdown condition under all Design Basis
- Events (DBE) which could result in a loss of offsite power or requiretheassumptionofalossofoffsitepower(exceptstation blackout). In addition, single failure criteria must be met. The
- following discussions review the expected electrical /DG system
- requirements under specific DBEs to define the worst case load and load profile.
6.1.1 Worst Case Load
- A process of elimination is used to determine the worst case load by looking at the equipment required to respond to a DBE. This is i discussed below. -
6.1.1.1 Reactor Trip and Coincident Loss of Offsite Power A reactor trip and coincident loss of offsite power where the Reactor Coolant System (RCS) and the Steam Generator secondary

system remain intact require a minimal amount of equipment for safe shutdown. The basic systems required are raw water, component-cooling water, auxiliary feedwater, charging, containment cooling, andlowpressuresafetyinjection(shutdowncooling). In addition the operators would be expected to have the instrument air system in operation. 6.1.1.2 Uncontrolled Heat Extraction i The most limiting Uncontrolled Heat Extraction case would be a main steam line break in containment which would require automatic In this case the Raw initiation Water of Component (RW), Engineered Safety (Features. Cooling CCW), Charging (CH), Auxiliary Feedwater (AFW) sequential start of FW-6, Containment Filtering and Cooling (VA) Containment Spray (CS), High Pressure Safety Injection (HPSI), and Low Pressure Safety Injection (LPSI) systems will be i automatically aligned and sequentially loaded on the diesel generator. The initial loading is expected to be nearl y the same ) as a large break LOCA, however, once the RCS invente y has been i restored, the HPSI and LPSI pumps will operate on minimum I recirculation resulting in a reduced load to the diesel generators. l 6.1.1.3 LOCA The ESF response to a LOCA automatically aligns and loads the ESF l and auxiliary systems on the diesel generator. In the small break LOCA case, the LPSI pumps are expected to be on minimum i recirculation and not running at full load. In the case of a tube ~ rupture, containment spray is not required resulting in a smaller load on the diesel generator. In the large break LOCA scenario, the LPSI and HPSI pumps are expected to run at full flow until the SIRW Tank is emptied. This represents the largest load for the longest time. The large break LOCA loads will be used in all further discussions. 6.2 OG Peak Load and Load Profile The expected load is based on a large break LOCA for DG-1 2551 KW l and for DG-2 is 2421 KW (calculation #FC03382 Rev. 3, Attachment A 8.1). The peak loads are expected to occur after the final loads P have automatically sequenced on the diesel and accelerated to full i speed. I 6.3 . Worst Case Load Profile The large break LOCA load profile is based on loads which either , reduce over time as a result of accident mitigation or receive l automatic trip signals some time into the event. l

'6.3.1- Load Reduction Due to Containment Depressurization -
Load reduction over time occurs on the containment filtering'and - cooling fans (VA-7C, VA-70, VA-3A and VA-38).- These fans are initially loaded to 100% power when the containment air / steam , mixture is near 60 PSIG. As the steam in containment is condensed by the ' containment spray system and containment- filtering 'and cooling units, the containment atmospheric density is reduced causing the fans to unload. [ 6.3.2 Automatic Trip h The LPSI pumps meet the automatic trip criteria (no operator action rec uired). These pumps are tripped on RAS at which minimum safety 3 injection occurs at approximately 3740. seconds (USAR Section 1 6.2.5). l 6.3.3 Load Profile l The load profile is graphed in Attachment 8.8 for each diesel. l This load profile is based on the large break LOCA, as defined in ] Calculation FC03382 Rev. 3, Attachment 8.1 (Figure 1 and 2). 6.4 Test Data Reduction { ^ Due to the room specific configuration for each engine, testing wits !- used to establish the relation between outdoor ambient air and the
- room air temperature dependant functions of the diesel generators, '
i e.g., turbo charger inlet air temperature. 6.4.1 ThetestdatafromRev.Oofthisanalysis(usedinthisanalysis ! (See References 4.4 - 4.7)) was compiled using a thermocouple datalogger. The test data used in this analysis concerning the i exciters was obtained in the test procedures of MR-FC-90-073 discussed in the next section. The critical parameters used in this analysis are outside ambient air temperature, combustion inlet ! air temperature (turbocharger intake air temperature), generator
- inlet temperature and jacket water temperature. The analysis is i based on the following:
1
- a. Thermocouple average temperature for ambient air temperature.
- b. Thermocouple average temperature for turbocharger inlet temperature.
- c. Thermocouple for generator inlet air temperature. i s
Data reduction was accomplished in two steps. First, it was 1 determined that the data required could be compiled at 15 minute 1 4 J d

- temperatures. Second, averages were taken at each time interval where more than one thermocouple was used to measure the same temperature area.
6.4.2 The test data used for the exciter temperature discussion is based
, on MR-FC-90-073 and was obtained with RTD temperature detectors 4
with
- 1'F accuracy. The following temperatures were measured:
a. ! b. Avera! Sing 1 eof 3centermountedexcitercabinetRTDs. hand-held RTD temperature detector for room ' ambient temperature.
- c. Weather tower or the hand-held probe was used for outdoor ambient temperatures.
! 6.5 Enaine/ Generator Power Outout Criteria l l 6.5.1 Engine Capability L l The deration of engine capability limit based on temperature is to ensure that the ESF loads do not result in unacceptable engine wear and potential decreased reliability of the engine. This is ! interpreted as the engine 2000 Hr/Yr capability rating. To t quantify the engine reliability, Electro-Motive Division, General Motors Corporation (EMD) has established output ratings for its engines based on potential engine degradation over a specified
- 3eriod of time. The time intervals specified are 30 minutes, 4 4'
1ours, and 2000 hours. The time ratings provide a measure of' stress on the engine. Operation at the 30 minutes and 4 hour ' ratings should be minimized, however, the engines are expected to provide reliable performance even with brief excursions into the
- 30 minute and four hour rating range. EMD has developed these d I ratings based on detailed knowledge of the temperature related &L l engine stress caused by operation at elevated loads, and operating l experience with the engines (refer to Attachment 8.7). Following 4
an engine run that exceeds one of the interval ratings it should ! be inspected for abnormal wear and refurbished if required to j achieve the highest possible reliability for future use. 1 The 2000 hour rating is a guide to schedule maintenance frequency.
- 0)eration at the 2000 hour rating for 2000 hours would indicate t1at an inspection be performed at the end of the run.
l The acceptance' criterion is based on the 2000 hour rating, the goal ! being not to exceed this rating which is consistent with Technical
- Specification 3.7. .
i
EA-FC-90-062 Rev. 2 Page No. 19 eas The published engine ratings are based on turbo charger intake {0I 3 temperatures of 90*F. provided de-rating curves (Attachment 8.2).For These intake temperatures are straight line curves showing intake air temperatures versus percent of full load rating. The curve used is based on jacket water outlet temperature (JWOT) of either 190'F or less, or 200*F to 210*F. For the- purposes of this analysis where test data shows JWOT above 190'F, the 200*F to 210*F curve will be used. When jacket water outlet temperature and turbocharger inlet temperatures are known while the engine is heating up during the initial stages of operation, a time versus engine / generator output - limit can be plotted for the 2000 hour engine rating. Past test-data (used in Rev. O of this analysis) gathered during the initial stages of engine operation allow a heat-up rate to be determined. From this, jacket water temperatures vs. time can be predicted for other outdoor ambient temperature. In the highly unlikely event that a large break LOCA'were to occur shortly after the engine has completed its monthly surveillance, the 30 minute rating curve would be applied to the initial LOCA loads in excess of the 2000 hour rating. This would assure operation of the ESF loads based on EMD's expectations for engine performance. 6.6 Deratina Methodoloav 6.6.1 Engine Derating The limiting parameters for engine / generator power output (in kilowatts) are jacket water temperature and turbo charger air inlet temperature. The jacket water outlet temperature (JWOT) determines what turbocharger air intake temperature de-rating curve is applicable. The percent of standard rating versus elevated inlet temperature curves (based on jacket water temperatures) are shown in Attachment 8.2. The graph shows two deratings, the upper right curve is based on a JWOT of 190*F, the lower curve on a JWOT in the range of 200*F to 210'F. In this analysis, engine / generator power output is based on the 190*F curve when JWOT is 190*F or less, and the curve of 200'F to 210*F when JWOT is above 190*F. For purposes of this analysis, 208'F will be used as the maximum JWOT, based on A cylinderheadlife(refertoAttachment8.2). lM 6.6.2 Generator and Exciter Derating 6.6.2.1 The temperature limit for the generator is determined by taking the known upper limit of the generator and reducing it by the rise between ambient outside and the generator inlet temperature. 4

Instrument uncertainty will be included in a conservative manner.
' ' 6.6.2.2 Modification MR-FC-90-073 installed cooling in the exciter housing.
The testing done by the modification will be analyzed to determine the adequacy of the newly installed A/C units (VA-759A, VA-7598) g at outdoor ambient temperatures of 110*F. 6.7 Instrument Uncertainty This section discusses the expected uncertainties of the instrumentation used to measure the critical parameters of-ambient air into the diesel generator rooms, turbocharger inlet temperatures, generator ai' - cooling temperatures, and exciter g cabinet air temperatures. 6.7.1 Outside Ambient Air Temperature Test Data Uncertainty i Ambient Air entering the room was measured using 6 thermocouples g mountedattheroomairintakeandrecordedonadatalogger(this information was not used for the exciter discussion in this revision). Each of these type J thermocouples has an uncertainty of 2.2*C or 3.96*F. The data logger has a .72*F uncertainty, however, post calibration testing indicated an uncertainty of
.22'F. Using the square root of the sum of the squares method, the loop uncertainty for each thermocouple is 2 3.97'F.
The use of six thermocouples to measure the ambient air temperature will result in a more accurate reading. Using the error analysis method for multiple inputs of equal uncertainty as defined in Chapter 5 of " Data Reduction and Error Analysis for the Physical Sciences", reference 4.3, the overall uncertainty of the average temperature is reduced to the individual loop uncertainty divided
- by the square root of the total number of channels. For the ambient air case, the uncertainty would be 2 3.97'F//6 =
- 1.62*F.
3 The actual outdoor ambient air temperature will be the average reading minus 1.62*F, which is conservative. The outdoor ambient air temperature calculated in this manner is conservative because this temperature is used to calculate delta Ts between the outdoor i i ambientandothertemperaturesgreaterthanambient(jacketwater ' 4 outlet, turbo intake air, and generator intake air temperatures) i which produces larger delta Ts.

' 6.7.2 Turbocharger Intake Air Temperature Uncertainty The turbocharger intake air (combustion ' air) temperature 1 -
uncertainty was determined using the same method and equipment as the outside ambient air temperature. In the case of the i turbocharger air intake, nine thermocouples were used. The l expected uncertainty is
- 3.97'F//9 =
- 1.32*F. For the purposes
- of engine derating due to turbocharger intake temperature, any
- temperature rise of the turbocharger intake over ambient will be 4
increased by 1.32*F, resulting in a conservative derating. 6.7.3 Exciter Cabinet Internal Air Temperature Uncertainty i MR-FC-90-073 installed air conditioning units on each exciter i panel. Testing was performed by the modification to determine the effects of a failed A/C unit on the ambient temperature limits of ' the exciters. The test used 9 platinum RTDs which were mounted < l inside the exciter cabinet and connected to a datalogger. The A l above measuring devices have a 1*F uncertainty'for each RTD. as Only the center 3 RTDs will be used for determining the enclosure temperature wit.h the door open because these are located in the l 9 area of the most heat sensitive components. This provides an ! , uncertainty of
- 1*F/(3 = 0.58'F.
3 6.7.4 Generator Cooling Air Inlet Temperature Uncertainty , The generator cooling air inlet temperature was meosured using one thermocouple and the same datalogger as outside ambient air. The 4 expected uncertainty is
- 3.97'F. The 3.97'F uncertainty will be subtracted from the upper generator operating temperature limit, j which is a conservative application.

As a result of temperature limitations on the diesel generators imposed in 1990, steps were taken during the first quarter of 1991 [
.to improve the heat removal capabilities of the diesel generator radiators. Access doors installed in the exhaust duct above the radiator core allowed for steam cleaning and maintenance of the radiator cooling fins. Post maintenance testing confirmed a significant improvement in air flow across/the radiator cores. See

savings of 180 bhp can be assumed if the Ethylene Glycol engine coolant is replaced by treated water.

, 6.11 DG-1 and DG-2 Generator Temcerature Limits 1 4 ; j 6.11.1 Generator Peaking Duty Temperature Rating * ' i J _The generators' upper temperature limits can be derived from;the nameplate data of the generators which specify the rotor and stator insulation temperature rise limits. See Attachment 8.3 and the EMD Generator Characteristic Data, Attachment 8.4. The peaking stator rise limit rating is 105'C and the rotor rise limit is 70*C abeve 40*C(acommondesignnumber). From the generator data sheet,'the i load based rise at 2500 KW (which represents the peak DG loading by0 PPD)is56*Cforthestatorand50*Cfortherotorabove40'C. f The rotor is limiting which equates to a limit of. 60*C maximum A temperature (40*Cambient,plusa20*Cmarginintherotorbetween (S
- j. the 70*C limit and the 50'C load induced temperature rise).
i The operating temperature limits would be 60*C (140'F) minus'the i room inlet to the generator inlet temperature rise and correcting for uncertainty as shown in Equation 6.8 C and D. Attachments 8.19 i- through 8.22 provide plots of the generator inlet temperature rise. Using the data in Attachment 8.22-1 to determine generator air A > i inlet tem erature rise a limit of 120*F can be calculated for DG-1 m (140-(fl02.6+3.97) - (88.8 - 1.62))). Using the data from Attachment 8.21-1 to determine generator inlet air temperature rise, a limit of 114*F can be calculated for DG-2 (140 - ((110 + 3.97)-(90-1.62))). ! Please note that when using the data, or graphs in Attachments 8.19 i' through 8.21 the data taken when the room fan is off should be used, since fans VA-52A and VA-528 are not to be in operation. l 6.11.2 This judgement is supported by the ratings of the Class H insulated j stator and Class F insulated rotor. Looking at motor insulation ratings (which can provide information on the insulation systems), Class F insulation is capable of 105'C rise above a 40'C ambient i and Class H insulation is capable of 125'C rise above a 40*C A ambient.

EA-FC-90-062 Rev. 2 1 Page No. 26 eas ; i- t l 1 , t. 6.12.1 Exciter Limit with Left Door Open, Air Conditioner Off Modification MR-FC-90-073 installed an air conditioning unit on l each diesel generator exciter cabinet to provide cooling for the I components inside the cabinet. The temperature ratings for this configuration will be analyzed and discussed later. This section will develop temperature limits for each exciter with the A/C unit off and the left door open. 6.12.2 Exciter Test Data EDG test data obtained in MR-FC-90-073 will be used to ' develop exciter ambient temperature limits with the A/C unit off and the lef t door open. This will establish a set of limits for the exciter if the A/C units were to fail. 6.12.2.1 Testing Procedure T-1 for_ DG-1 from MR-FC-90-073 (5/30/91) . l This test ran the diesel at approximately 2500 KW throughout the A test. RTDs(9)weremountedinsidetheexcitercabinettomeasure e the internal cabinet temperature. The average of the center 3 temperatures will be used as the ambient air temperature which will be used to calculate the delta T between outside ambient and cabinet temperature. Attachment 8.15 shows that at 15:46:05 the cabinet temperature stabilized with the left door open and the A/C unit (VA-759A)off. The average of the 3 center cabinet readings is: T3yg = 99.9 + 100.1 + 100.2 = 100.1*F 3 ! .The outside ambient temperature at this time was 80*F (T3 from page 9 of T-1 from MR-FC-90-073 is the weather tower thermistor). Therefore, the delta T between the outside ambient and the cabinet , temperature is calculated with instrument uncertainty as follows < (refertoequation6fromSection6.8): i AT = T3yg + 1*F - T m = 100.1 + .58 - 80 = 20.68'F (3 The outdoor ambient could reach 101'F (122*F - 20.68'F) and the
- exciter would still be expected to function with no A/C and the

The delta T between the outside ambient.and the cabinet temperature is calculated with instrument uncertainty for the cabinet temperature as follows (refer to equation F from Section 6.8): AT = T3ya + 1*F - Tm = 92.3'F +. 58 - 76.9'F = 16*F (3 The outdoor ambient could reach 106*F (122'F - 16*F) and the exciter would still be expected to function with no A/C and the left door open. ; 6.12.3 Exciter Test Data (A/C On, Door Closed) This section will demonstrate that the VA-759A and VA-759B exciter air conditioners will maintain the internal exciter cabinet air temperature below the 122*F limit. The exciter A/C unit on each diesel generator was tested by MR-FC-90-073. The testing obtained A/C duty cycles at known temperature differentials (betweencabinetinteriorandexterior). 6.12.3.1 DG-1 Exciter A/C Test The diesel generator was run at approximately 2520 KW for 1 hour with the A/C unit (VA-759A) cooling the exciter cabinet. At the beginning of the test, the A/C unit duty cycle was approximately 56% while removing primarily the heat generated internal to the i exciter cabinet. The average internal cabinet temperature averaged I around 80*F. The room ambient temperature rose from 81*F to 100'F i within 1 hour. At the end of this part of the test, the A/C unit ! duty cycle increased to approximately 64% to maintain a 20*F delta l T between the room ambient and the internal cabinet temperature. ' Predicting the A/C unit duty cycle at 110'F outside' ambient is
~
accomplished a's follows: For a 20*F increase in delta T between internal cabinet and room ambient, the A/C unit duty cycle increased 8% based on a 100% duty i

.i EA-FC-90-062 Rev. 2 '
Page No. 28 eas i cycle. Therefore, there is a 8%/20*F = 0.40 percent increase in , duty cycle per 'F increase in. delta T between room ambient and internal cabinet air temperature. At the time of the test, the outdoor ambient temperature will be assumed to be 74*F which is' I conservative (actual temperature went from 74'F to 78'F during the ' test). An outside ambient of 110*F is an increase of 36*F over 74*F. At 0.40% per 'F this gives a 14.4% increase in duty cycle which when added to 64% cuty cycle gives a duty cycle of approximately 78%. The above does not account for the increased A/C unit efficiency from approximately 70% to 92% at higher g operating temperatures as discussed in Attachment 8.18. Since the above discussion is based on maintaining the cabinet internal temperature at 80*F with a 110*F outdoor ambient at a 78% duty cycle at reduced efficiency, it is judged that there is enough margin to assure an internal cabinet temperature of less than the : required 122'F upper limit with an outdoor ambient of 110*F. 6.12.3.2 DG-2 Exciter A/C Test The analysis for the A/C unit (VA-7598) for DG-2 will be discussed different from that of DG-1 since the room ambient at the start of the A/C unit test was approximately 7'F higher than the internal cabinet temperature. The A/C unit test ran for about I hour with the A/C unit cooling the exciter cabinet at a diesel generator load i of 2540 KW. At the end of the test the A/C unit duty cycle was approximately 50%. The average internal cabinet temperature was 80*F and the room ambient was 89'F. . Therefore, the A/C unit A maintained a 9'F differential between the room ambient and the C6 internal cabinet temperature with a 50% duty cycle. From
~
- Attachment 8.18, the A/C unit efficiency was approximately 60%. .
- Therefore, it is judged that the A/C unit would be able to maintain !
! a 9'F differential or better between room ambient and the cabinet 4 internal temperature due to the available margin in the A/C unit by the increase in duty cycle and efficiency as temperatures rise.
. From Revision 1 of this analysis, it was found that there was a l
17'F delta T between the outdoor ambient and the room temperature. , Therefore, the room ambient could reach 127'F with a 110'F outdoor ambient temperature. It is judged that the A/C unit would be able to maintain an A . enclosure temperature of less than 122'F at an outdoor ambient of Le , 110*F. i 1 k l

These temperatures allow each diesel generator to operate within its 2000 hour rating for the LOCA analyzed here. Additionally, the generator and exciter cabinet (with A/C running) are not expected to see temperatures which would exceed their limits at an outdoor ambient temperature of 110*F. The VA-52A and B fans shall be "0FF" when the respective diesel is run. Through the course of the accident (LOCA) the diesel generator will unload such that the load will always be below the 2000 hour rating of the engine. The KW margin between the actual load and the 2000 hour rating is available for addition equipment starts, for the large break LOCA analyzed here. Actual margin is dependant on the pump loads and ambient air temperature. The conclusions of this EA have been superseded by calculation FC5916 Rev 3. Some of the . information provided in this EA were used as input for the new calculation. [

SUMMARY
SHEET Rev. No. 3 METHODS The load information for equipment dead loaded on the j I diesel generators will be calculated and summarized using the ELMS printout and the ELDL data base (See Inputs). d
- The Load Shed Information Summary will include the load l shed status and electrical load in KW for each item i listed.
, The load (in KW) for each motor can be determined by: P (in KW) = IRated HP1 x 0.746 KW/MP
% efficiency l The load (in KW) for each load given in KVA can be
, determined by: P (in KW) = [ load (in KVA)] x [ power factor] The Load Shed Information Summary for DG-1 includes 4.16KV Bus lA3 and all 480V Buses fed from 1A3. These 480V Buses are 1B3A, 1B3A-4A, 1B3B, 1B3C and 1B3C-4C. Also included in the summary is any 480V MCC that is fed from one of the aforementioned 480V Buses and is not load l
- shed. These MCC's are MCC-3Al, MCC-3A2, MCC-3B1, MCC-3C1 l
! and MCC-3C2. l l - . The Load Shed Information Summary for DG-2 includes ] 4.16KV Bus lA4 and all 480V Buses fed from 1A4. These l l 480V Busos are 1B4A, 1B4B, 1B3B-4B and IS4C. Also
- included in the summary is any 480V MCC that is fed from l one of the aforementioned 480V Buses and is not load
- shed. These MCC's are MCC 4Al, MCC-4A2, MCC-4B1, 1
MCC-4B2, MCC-4C1, MCC-4C3 and MCC-4C4. Please note that load shed means 4.16KV load shed, 480V i under voltage breaker trip, ESF 480V load shed, OPLS load shed and those control circuits which drop out as a result of loss of offsite power and require manual starting. The value (in KW) of the load for each device which is load shed or is sequentially loaded'will be placed in the
" LOAD (KW)" column of the Load Shed Information Summary.
Each device which is not load shed needs to be examined 4 to determine whether it is a continuous or intermittent load (such as valve cycling). _ i 1 m PED-QP-3.31

SUMMARY
SHEET Rev.No. g METHODS The value (in KW) of a continuous load will be placed in the " LOAD (KW)" column while the value of a intermittent load will be placed in the " INT LOAD" column of the Load Shed Information Summary. Also included in the summary will be the cycle time (in i seconds) for any applicable valve listed. Once the Load Shed Information Summary is completed, a total will be determined for non-load shed continuous . loads, non-load shed intermittent loads and sequential ) As noted in the assumptions, the inte mittent loads. l i loads are not considered part of the total long time j running load on the diesel generators. The total load on each diesel generator is equal to the sum of the total not load shed continuous load (dead load) and the total sequential load. The ' expected containment cooling fan load will be estimated based on 100% load at maximum containment pressure and 50% load during " normal" condition - no i steam / air atmosphere. It will be limited for the purpose of this calculation to a minimum long term load of 75% of motor name plate rating. Horsepower used for the sequential loads are based on the
- brake horsepower requirements of the driven pumps.
Operating points are shown on the pump curves included in this c'alculation. g ! A separate table has been added to calculate the expected power factor of the diesel generator load. KVAR is based on nameplate horsepower rating. KVAR based on nameplate rating will be used for both lightly loaded and overloaded cases. KVAR will be determined by: KVAR = KW( ( 1/pf2)-1 1 1/2 E PED-QP-3.31

SUMMARY
SHEET Rev.No. 3 ASSUMPTIONS
- 1. Non-load shed loads which are used intermittently
-are not considered to be part of the total longer term load on the diesel generators.
- 2. Equipment which is used infrequently, such as welding receptacles and stress gallery disconnect'~
switch, are assumed to have no load.
- 3. When % efficiency or power factor information is not i available, a power factor = 0.80 and a % efficiency =
0.95 will be used as typcial values for electrical equipment.
- 4. The diesel generator model assumes that the sequenced load group has accelerated to full speed and is running at expected load.
- 5. RAS is assumed to occur with minimum safeguard actuation maintaining the highest diesel loading for the maximum expected time on each diesel generator.
- 6. This model assumes that no manual restart of equipment such as air compressors, turbine plant cooling pump, and Auxiliary Building ventilation fans occurs.
, 7. The calculation represents the worst case in that equipment which could be running (not intermittent) is running on each safeguard train at the time of !, the loss of offsite power and DBA.
- 8. For conservatism, the battery chargers are assumed at full load.
- 9. SI-3A, 3B, and 3C motors are assumed at 92%
efffciency since the motor nameplate states full l load amps at 340 amps. When 92% eff and .90% pf are used to calculate the above SI motor amps, 339.2 amps is obtained as follows: - 300 ho x.746KW/ho = 339.2 amps.

SUMMARY
SHEET Rev.No. 3 ASSUMPTIONS
- 10. KVAR for an induction motor will not change significantly from the nameplate value with either a lightly loaded motor or motor loaded into its service factor, see reference 16 section 6.4.
- 11. For the purposes of determining the load losses of-the unit substation transformers it is assumed that the dead load is equally distributed between the transformers connected to each diesel generator.
Since the dead load is small when compared to the sequenced load this assumption little effect on the results.
- 12. Certified test reports could not be retrieved for unit substation transformers T1B-4A and T1B-4C. For i the purposes of determining the transformer losses '
the no load and load loss values for these transformers will be assumed to be . equal to the highest values of the other transformers. This assumption is reasonable because the variance in measured losses of the six transformers in the test report is 1% and the losses of T1B-4A & T1B-4C will be comparable. a J i PED-QP-3.32

SUMMARY
SHEET Rev.No. 3 i CONCLUSIONS 1 Attached are the Load Shed Information Summaries for DG-1 and
- DG-2. These summaries note the load shed status for each
- device, the load in KW, the intermittent load (if
- applicable), and the cycle time (in seconds) for appropriate j valves.
] ! To determine the loading on each diesel generator, the total sequential load and the total non-load shed continuous load are needed. The total non-load shed intermittent load will l also be found. i Reference the attached Load Shed Information Summary for DG-1
- for load information on individual equipment loaded on DG-1.
i The load totals for DG-1 are as follows: Total Non-Load Shed Intermittent Load: 61.3 KW. l Total Non-Load Shed Continuous Load: 302.1 KW
- Total Sequential Load
- 2248.9 KW i
Therefore, the total load which would be loaded on DG-1 as a l result of LOCA coincident with a loss of offsite power is I 302.1 KW + 2248.9 KW = 2551.0 KW After approximately 2000 seconds into the event, the l ventilation fans VA-3A and VA-7C would be expected to unload 4 by approximately 25% of rated KW or 73.6 KW and SI-3A will be at 336.8 hp which is a 17.8 hp increase over the 319 hp (17.8 l hp = 14.4 KW for SI-3A). This would reduce the load to
- approximately 2549.1 - 73.6 + 14.4 = 2491.8 KW.
1 1 At RAS 3740 seconds into the event (minimum safety injection), SI-1A trips reducing the load by 256.1 KW. SI-3A's bhp increases to 338.8 hp which is a further 2.0 hp increase over the 336.8 hp (2.0 hp = 1.6 KW for SI-3A). These two events reduce the load a further (256.1 - 1.6)KW to
- 2491.8 - 254.5 = 2237.3 KW.
I For the lona term loadina (based on automatic load reduction , only and no operator action to reduce the load - refer to 1 OPPD calc. FC05522 for long term loading based on operator ' action), SI-3A will be assumed to' be at 343 hp (0 psig , containment pressure) for conservatism (refer to Attachments
- A & B). Therefore, the load will increase another (343 hp -
338.8 hp) = 4.2 hp which for SI-3A is equal to 3.4 KW. Long term KW load = 2237.3 + 3.4_n 2240.7 KW. This final long , term loading is assumed to occur at 5000 seconds for conservatism (Ref. USAR Figure 14.16-2, Attachment A). m.1 PED-QP-3.34 i

SUMMARY
SHEET Rev.No. 3 CONCLUSIONS Reference the attached Load Shed Information Summary for DG-2 for load information on individual equipment loaded on DG-2. The load totals for DG-2 are as follows: Total Non-Load Shed Intermittent Load: 208.6 KW Total Non-Load Shed Continuous Load: 594 4 KW Total Sequential Load: 1826.2 KW Therefore, the total load which would be loaded on DG-2 as a result of LOCA coincident with a loss of offsite power is 594.4 KW + 1826.2 KW = 2420.6 KW After approximately 2000 seconds into the event, the ventilation fans VA-3B and VA-7D would be expected to unload by approximately 25% of rated KW or 73.6 KW and g48 pf SI-3AC & 3B bhp would increase to 325 hp each (total ggjql increase of 40.5 KW). These two events reduce the load further (73.6 KW - 40.5 KW) to 2420.6 KW - 33.1 KW = 2387.5 KW, At RAS 3740 seconds into the event (minimum safety injection), SI-1B trips, reducing the load a further 256.1 KW to 2131.4 KW. - The calculated power factor for the diesel generators
- are:
DG-1 0.87 pf DG-2 0.85 pf i ! These power factors are larger than the nameplate rating l j of .80 at 2500 KW and demonstrate that the LOCA loads are
- expected to operate within the generator and exciter i ratings.
Diesel Generator loading 'has a direct effect on diesel i generator fuel oil consumption, reference FCS Tech Spec. 3 2.7, and the following calculations should be reviewed for affects of load changes any time this calculation is revised.

PRODUCTION ENGINEERING DMSION CALCULATION SHEET Rev.No. 3 REF. i NO. 2.0 EXPECTED CONTAINMENT FAN LOADING f ! The expected percentage (%) of nameplate loading for the ! containment ventilation fans VA-3A, VA-3B, VA-7C, and VA-7D is a function of atmospheric density within containment. The loading is expected to follow the containment pressure. The graph on the next page shows the expected 2 profile.
- containment profile (two cases are shown) and an expected
- time load curve. The curve loading extremes are bounded by I
full load at maximum DBA pressure and 50% load at normal pre-DBA environmental conditions. For the purposes of this
- calculation, the minimum post-DBA load will be assumed to 1 be 75% for conservatism.
i Fan curves are available from the vendors test report, Joy Manufacturing Performance an Sound Level Test of Joy j Axivane Fans, 07/24/70. This document can be retrieved 1 from the DBD database, WIP 61095. Quality of the document
- is too poor to be reproduced and included in this calculation. The curves show that motor nameplate horsepower exceeds the maximum fan required bhp.
Therefore, this calculation uses the motor nameplate for conservatism. i e i i l 1 I q..

FROM: B. J. Van Sant l l TO: R. F. Mehaffey
SUBJECT:
Motor Horsepower Estimate for SI-3B and C pump operation 1 i Per your request, DEN-Mechanical has performed an informal calculation to determine the motor horsepower requriements for the containment spray pumps. We have analyzed the performance of the B and C pumps operating through two j heat exchangers and two spray headers. l The results of the analysis show the pumps to supply 2650 GPM each at 0 psig
- in containment. At 60 psig the pumps will suppyh 2125 GPM each. The motor
- horsepower per pump is 325 and 295, respectively, i'
The analysis assumed the SIRWT was at Technical Specification minimum. This j is conservative since the level will drop during the accident. The analysis
- also assumed nominal pump performance. This is also conservative since the actual pump performance is slightly degraded.
i Although the analysis was informal, it has been checked. The analysis was
- based on resistance values derived in the Combustion Engineering's (C-E) calculation for Spray Pump performance. Those resistance values were used to develop system curves for the two header, two pump hydraulic model. The head
. curves for the two pumps were combined, and the intersection with the system curves for 0 psig and 60 psig containment pressure were plotted. C-E is perfoming a design basis calculation to verify the values given here. DEN-Electrical will be notified of any changes at that time. If you have any questions, contact Jon Ressler at extension 2426. B. J. Van Sant Supervisor - Mechanical Engineering i Production Engineering c: R. L. Phelps J. L. Skiles R. E. Lewis R. G. Eurich R.
