This maximum limit also assures that single l failure criteria are met. 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 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 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 equipment to enhance shutdown, i.e. an air compressor. 2.5 Determine maximum ambient temperatures for which the DG's are operable. 110'F has been established as a goal for diesel ambient 4 . air operating limits, based on review of meteorological data for i i this area predicts that 110*F will not be exceeded as an outdoor ambient air temperature. 3.0 INPUTS TO THE ANALYSIS 3.1 Calculation number FC03382 Rev. 3, Diesel Generator LOCA Loads 3.2 Power Systems Analysis of FCS Generator Capabilities 3.3 EMD Specification Sheet.for the Generator 3.4 Diesel Generator Nameplate data 3.5 Tables from the " Standard Handbook for Electrical Engineers" 3.6 ES-87-12, FCS Weather Tower Uncertainty Calculation #FC01381, Rev.

OFFICIAL we r 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 engine / generator can operate the worst case safety-related loads in response a 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 performance and test data to project DG room temperature rise above outside i ambient air..The analysis also demonstrates that the static exciter and generator can operate at the analyzed higher temperatures.

EA-FC-90-062 Rev. 2 Page No. 15 eas 0, :D '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. Perform an Engine Derating Analysis and establish Operating Temperature Limits based on Jacket Water and Turbocharger inlet air temperature. 7.

Determine margin for additional loads. 6.1 Worst Case Load and Load Profile l The Fort Calhoun Station is required to have sufficient onsite electrical generation capacity to safely shutdown the reactor and i 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 'l i

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 initiation of Engineered Safety (Features.In this case the Raw Water (RW), Component 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 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 restored, the HPSI and LPSI pumps will operate on minimum recirculation resulting in a reduced load to the diesel generators. 6.1.1.3 LOCA l The ESF response to a LOCA automatically aligns and loads the ESF and auxiliary systems on the diesel generator. In the small break LOCA case, the LPSI pumps are expected to be on minimum 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 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. 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 automatic trip signals some time into the event.

EA-FC-90-062 Rev. 2 Page No.'17 L eas-ra m f l u_. v. ;) '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: 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 4 J d

This-was done due to the relatively slow rate of change of the observed 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 with

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 quantify the engine reliability, Electro-Motive Division, General t 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 ratings based on detailed knowledge of the temperature related &L engine stress caused by operation at elevated loads, and operating experience with the engines (refer to Attachment 8.7). Following an engine run that exceeds one of the interval ratings it should 4 be inspected for abnormal wear and refurbished if required to j achieve the highest possible reliability for future use. 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 {0I 3 The published engine ratings are based on turbo charger intake provided de-rating curves (Attachment 8.2).For intake temperatures temperatures of 90*F. These 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

The testing done by the modification will be analyzed to determine g the adequacy of the newly installed A/C units (VA-759A, VA-7598) 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 g

temperatures, generator ai' - cooling temperatures, and exciter cabinet air temperatures. 6.7.1 Outside Ambient Air Temperature Test Data Uncertainty i Ambient Air entering the room was measured using 6 thermocouples mountedattheroomairintakeandrecordedonadatalogger(this g 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.

The actual outdoor ambient air temperature will be the average 3 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 ambientandothertemperaturesgreaterthanambient(jacketwater outlet, turbo intake air, and generator intake air temperatures) 4 i which produces larger delta Ts. A larger delta T will give a larger temperature rise above ambient for the system being analyzed yielding a conservatively lower upper temperature limit for that i system. l i i i i l S b

i i l' Rev. 2 EA-FC-90-062 Page No. 21 eas r '. a. - rP 4 is ' 6.7.2 Turbocharger Intake Air Temperature Uncertainty The turbocharger intake air (combustion ' air) temperature uncertainty was determined using the same method and equipment as 1 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 panel. Testing was performed by the modification to determine the i 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 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 area of the most heat sensitive components. This provides an 9 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 expected uncertainty is

• 3.97'F.

The 3.97'F uncertainty will be 4 subtracted from the upper generator operating temperature limit, j which is a conservative application. 6.7.5 Weather Tower Outside Ambient Temperature Uncertainty ~ The weather tower 10 meter air temperature can be used to determine the margin available to manually load additional equipment on the diesel generators. ES-87-12, Weather Tower Instrument Uncertainty Calculation FC01381 (Input 3.6), established a temperature uncertainty for the ERF computer readout of * .71*F. This uncertainty is not considered significant, the reading alone without correction can be applied.

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

• 091Rev.0)receivedfromMKPowerSystems,OPPD'srepresentative for EMD stationary diesel generating units, a net horsepower savings of 180 bhp can be assumed if the Ethylene Glycol engine 4

coolant is replaced by treated water. This can be converted to an J l additional 130 Kli to be applied to offset the diesel generator ,\\ deration curve. The addition of 130 KW to the rated capacity of 3 2654 yields 2784 KW available. The diesels will satisfy the post-LOCA loads if this 2784 KW power available is applied to the 2000 hr. deration curve. The combined benefits of a "near new" cleaned condition of the radiator in conjunction with efficiency savings associated with changing coolant from Ethylene Glycol to treated water result in 3 higher output capacity such that the temperature 1imit could be Oi raised.

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 the 70*C limit and the 50'C load induced temperature rise). j. 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 inlet tem erature rise a limit of 120*F can be calculated for DG-1 m i (140-(fl02.6+3.97) - (88.8 - 1.62))). Using the data from !.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.

These exciters were. part of the origin ~al EDG installation and ar'e approximately 20 years old. G.E. (Letter dated July 20, 1990,.6) has stated that the open exciter panel will have 'd no problem operating at 50*C (122*F). i

EA-FC-90-062 Rev. 2 Page No. 26 eas t i-t. 1, 6.12.1 Exciter Limit with Left Door Open, Air Conditioner Off Modification MR-FC-90-073 installed an air conditioning unit on 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). 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..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 left door open. l 6.12.2.2 Testing Procedure T-2 for DG-2 from MR-FC-90-073 (5/15/91) 4 l This test was performed identical to the test for DG-1. Attachment 8.16 shows that at 14:57:27 the exciter cabinet temperature 4 o

The average of the 3 center cabinet readings is: Tag = 91.3 + 92.0 + 93.6 = 92.3*F 3 The outside ambient temperature at this time was 76.9'F which was measured using MT-00014 which was post-mod tested at better than 1*F uncertainty (per Attachment 8.17) and therefore will be used with no uncertainty. 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 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 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' 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 g A/C unit efficiency from approximately 70% to 92% at higher 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 ~.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

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 diesel generators will be calculated and summarized using d I the ELMS printout and the ELDL data base (See Inputs). 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 shed. These MCC's are MCC-3Al, MCC-3A2, MCC-3B1, MCC-3C1 and MCC-3C2. l The Load Shed Information Summary for DG-2 includes ] 4.16KV Bus lA4 and all 480V Buses fed from 1A4. These 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 under voltage breaker trip, ESF 480V load shed, OPLS load i 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 to determine whether it is a continuous or intermittent 4 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 loads.

As noted in the assumptions, the inte mittent 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 g this c'alculation. 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: 1/2 KVAR = KW( ( 1/pf2)-1 1 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 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. = .92eff. x.90 x 1.73 x.46KV M PED-QP-3.32

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 by approximately 25% of rated KW or 73.6 KW and SI-3A will be 4 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 p SI-3AC & 3B bhp would increase to 325 hp each (total f 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 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. 2.7, and the following calculations should be reviewed 3 for affects of load changes any time this calculation is revised.

The loading is expected to follow the containment pressure. 2 profile. The graph on the next page shows the expected 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.

SUBJECT:

Motor Horsepower Estimate for SI-3B and C pump operation 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.

Dear Mr. Schwartz:

1 GE Nuclear Energy has forwarded Omaha Public Power District's (OPPD) request per the referenced letter to the appropriate GE Business Operation. GE Drive System, Sales, Virginia, technically responsible for the subject static exciter. following: GE Drive System after review of OPPD's request offers the The subject Exciter System was originally manufactured and o shipped by the Wayneboro. Virginia Plant 20 years aoo. This business moved to Sales, Virginia le years ago. No technical data folder is available for this exciter in the o files. It is most likely the esciter was a special application for this o diesel generator vendor, i The excitar panel supplied by GE was placed in an enclosure along o with other support equipment to comprise the Emergency Diesel Generator (EDG) vendor's total systas. Because of the aforementioned. GE cannot provide OPPD with a cost quotation as requested irr the referenced letter, since we have no technical data upon which to base an investigation. However, it is our opinion the open a 50 degrees C ambient temperature.emetter panel as originally supplie GE recommands OPPD contet the EDG vendor and obtain heat 'run total system to get tr.e appropriate answers they seek.

F reency Diesel C;;;rators at FCS Telecen Summary: (IncludingDecisionsandCommitments) I called Marty to discuss in more detail why EMD judged that operation of OPPD's Emergency Diesel Generators above the 2000 hr. KW output rating was acceptable. Marty stated that these ratings were developed in and came into effect in 1966 in response to requests for information about the output capabilities of these engines in emergency applications. The ratings were based on a knowledge and i review of temperature within the engine and at the cylinder head. This is j supported by experience with the engine. i 2 l l Action Reouired: i None 1 Distribution: e J l i e 1 c,_

The lower ambient air temperature to the radiator (110*F) will also result in lower DG water jacket outlet temperatures. The lower DG water jacket outlet temperature would be offset slightly by the 2.1% increased heat rejection of DG-1. Therefore it can be concluded from the Young Radiator analysis model and actual test parameters that 208'F DG water jacket temperature can be achieved with 110'F ambient outside air temperature.

SUMMARY

(Including Decisions & Consnents) Dan called Wes Batchelor to pursue Rich Ronning's concern of whether or not the 33 Btu / MIN./ BHP heat rate used in the Young Radiator heat transfer analysis included heat input from the lube oil cooler. Wes confirmed that this number includes all engine related heat loads (including l L. O. Cooler) and is the number used for sizing radiators. ACTION REOUIRED: None i 4 DISTRIBUTION: ~ c: R. R.

• This comparison also reveals that both units are essentially performing the same, i.e., measured flows are nearly equal.

Radiator fan' output at test conditions was adjusted to a standard condition of 70*F to determine base SCFM delivered by the unit. Temperature correction factors were then applied to account for decreased air density at elevated temperature and compared to required flows to maintain jacket water temperatures at or below 208'F. As can be seen from Attachment 8.9d-2 and 8.9d-3, the radiator vendor predicts that the FCS diesel generator radiator configuration is adequate for operation at up to 114*F ambient temperature for DG-1 and 117'F for DG-2.

1. Engineering Analysis FC-90-062 Rev. 1 " Diesel Generator Upper Temperature Operating Limits" i 2. Engineering Analysis FC-90-091 Rev. O " Improving the Performance of the Emergency Diesel Generator Jacket Water i Cooling System" The purpose of this memo is to provide high confidence level results of the changes made to the DG cooling systems to raise the ambient air temperature limit. The recent installations of local air conditioning units.on the exciter cabinets will allow operation of the exciter at 110'F ambient conditions. The ambient air temperature limitations on the engine, previously l established in EA-90-062 Rev. 1 (Ref. 1) are 103'F for DG-1 and 100'F for DG-2 to ensure that the 2000 hr. deration curve was not exceeded. The engine ambient air temperature limits are increased to 110*F based upon 4 reduction of mechanical load and improved heat transfer associated with changing coolant to treated water together with benefits achieved by cleaning I the radiators on both diesels. Specific details regarding the actions taken to increase the ambient air temperature limitation on DG-1 and DG-2 is provided in attachment "A" to this memorandum. I i Based on the information that DEN has obtained from MK Power Systems, Young i + Radiator, Station Engineering and Stone & Webster Engineering, DEN concludes, with a high degree of confidence, that the diesel generators will not be limited by jacket water or turbo charger temperatures at ambient temperatures 4 below 110'F if treated water is used in the Jacket Water system. While this is a high confidence level conclusion, EA-90-062 Rev. 1 must be revised, reviewed and independently reviewed per the requirements of QP-5 " Engineering Analysis Preparation, Review, and Approval" to fully document this conclusion. Although an elevated ambient air condition test is not required due to the i documented test data recorded in EA-90-062 Rev. 1 and EA-90-091 Rev. O, it would lend further credibility to the engineering analysis and ensure that it withstood regulatory scrutiny. Warm weather testing is strongly recommended by DEN to validate the revision to EA-90-062 Rev. 1. Recommended maintenance and construction activities associated with the near and long term operation of the diesels are provided in Attachment "B". 4s-sto-

In the interim, this memo is considered as support for establishment of diesel generator operability at or below 110'F, if. treated water is used in the Jacket Water system.- If ethylene gycol is used as a cooling medium, the ambient temperature limit will not increase above the previously established values of 100*F for DG-2 and 103*F for DG-1.

O concluded that there was no improvement',in lowering jacket a 4 water temperature by replacing 50/50 Glycol coolant medium with a treated water medium. OPPD DEN has since obtained Young Radiator data relating to performance of different coolants. The conclusion in EA-90-091 Rev. O is.in conflict with anticipated jacket water temperature performance normally 3 expected in this type of equipment. Young Radiator has performed calculations which indicate that the coolant temperature will be maintained at 208'F (using treated water as a coolant) with a design heat input of 120,970 BTV/ MIN, a j coolant flow of 1100 gpm, and with cooling air entering the radiator at 115'F at a flow rate of 104,852 CFM (93,000 scfm, standard conditions). Because 1 water has a higher specific heat (C ) (1.0 BTU /lb *F) than 50/50 Glycol (.85 BTU /lb'F)andalowerdensityand$iscositythanEthyleneGlycol,ahigher temperature limit of 115'F vs. (EA-90-091 Rev. 0) 100*F and 103'F should have been predicted due to improved heat transfer and reduced pumping requirements. l Test data collected in EA-90-062 Rev. I was reevaluated by DEN and it has been con.cluded that the test data collected during operating runs on DG-1 confirms i there is a substantial reduction in jacket water temperature when treated i water is utilized as a coolant medium. In reevaluation of the test data, data points collected during the first 30 minutes of a diesel run were excluded to ensure that the diesel had reached a steady state condition.

This data is summarized in Table II. Table 11 COMPARISON OF JACKET WATER TEMPERATURES TO AMBIENT AIR TEMPERATURES DG-2 Test. Ambient Jacket Water AT Jacket Water Coolant Coolant pitg Air Temo *F Temo *F to Ambient Air Flow Medium 7/16/90 87 192 105 1096 Glycol 7/17/90 89.5 194 105 975 Water 9/6/90 89 195 106 Water During testing of DG-2 on July 17, 1990, the coolant flow fluctuated repeatedly and was considerably below its expected value of >1100 gpm. DEN suspects that the coolant system may not have been adequately vented following the coolant change, an AMOT valve did not perform as designed during this j test, or the flowmeter malfunctioned. As no jacket water flow data is available for subsequent DG-2 tests conducted at elevated ambient air temperatures, this problem may have persisted. It should also be noted that the radiator for DG-1 was not as severely fouled as the radiator for DG-2, and that the fouling factor for DG-2 could have been the dominant element in DG-2's reduced heat transfer capability. Removal of Debris from Diesel Radiators l DEN has evaluated the benefits of the cleaning that was performed by Fort i Calhoun Station maintenance on air flows through the diesel generator radiators. To aid in this evaluation, Station Engineering performed extensive testing of air flows in the diesel radiator exhaust ductwork and supplied DEN with the results. Using raw data, there was no apparent measurable improvement in air flow, however, in order to compare fan flows taken under varying air temperature conditions, the delivered air flow must be corrected to indicate the air flow that would be delivered if the inlet air was at a temperature of 70*F. This correction is required because fan output is a function of air density, i.e., less fan SCFM output occurs at higher temperatures. Table III sumarizes the data collected from testing performed before and after cleaning the radiators on diesel generators DG-1 and DG-2. I 1

EA-90-091 Rev. O concludes that a l'F gain in ambient allowable temperature corresponds to each 1000 SCFM of additional air. This infers that an additional 2'F ambient allowable is gained by cleaning DG-1 and a 7'F gain was t j achieved on DG-2. This is a very rough correlation, but supports the predicted jacket water temperatures supplied by Young Radiator. The difference in air flows correlates well to the measured difference in jacket i water temperature and ambient air temperatures shown in Table I and Table II. t DG-2 showed a 7'F higher AT than DG-1, because of loss of air flow and combined with reduction of heat transfer surface area because of fouling. Efficiency Savinos Resultino From Coolant Chance According to literature (documented in EA-90-062 Rev. 1 and EA-90-091 Rev. 0) i received from MK Power Systems, OPPD's representative for EMD stationary j diesel generating units, a net horsepower savings of 180 bhp can be assumed if the Ethylene Glycol engine coolant is replaced by treated water. This can be converted to an additional 130 KWe to be applied to offset the diesel generator deration curve. The addition of 130 KWe to the rated capacity of 2654 yields 2784 KWe available. In a trial run performed by the DEN Electrical Group with the computer program used to graph attachments 8-6-3 and 8-10-1 of EA-90-091 Rev. O, the diesels will satisfy the post-LOCA loads if this 2784 KWe power available is applied to the 2000 hr. deration curve. This computer program utilizes t.he assumptions of EA-90-062 Rev. 1 that the demand occurs only while~the diesel is,in a cold standby condition and not immediately following a planned surveillance test run of the diesel operating considerations. d

a EA 90-062 ex-Fc-90-os2 Rev."T 3 q,g,qf.10-6 R &,. 3 ATTACHMENT "A" (Continued) Although it is satisfactory to operate the diesels at elevated jacket water temperatures when required to meet emergency demands, it is not recommended that this be done for normal surveillance testing. The jacket water temperature alarm sounds at 200*F, with diesel trip occurring at 208'F. This places the operator in the position of operating equipment in an alarmed 4 condition, which may not be desirable. i l l

EA-FC-90-062 ga-g0-062 Ree. n.10-7 gr # ^ qq-99 4 : " RE\\' 3 ATTACHMENT "B" RECOMMENDED MAINTENANCE AND CONSTRUCTION ACTIVITIES FOR DG-1 AND DG-2 DEN Mechanical also recommends that these maintenance and construction activities be performed as scheduled: 1. Replace the AMOT valve thermostatic elements to ensure reliability at elevated jacket water temperatures. 2. Replace the radiator cooling fans with units designed for higher output at the differential pressures observed. 3. Upgrade the instrumentation associated with the diesel generator jacket water cooling system (MR-FC-90-005). 4. Establish a Preventive Maintenance Procedure for cleaning the finned surface of the radiators. 5. Change coolant back to 50/50 Glycol to prevent freeze damage after October 15 each year and run treated water from May 15 through October 15 of each year. Until other improvements in cooling air flow can be implemented, the coolant should be changed to treated water in May and returned to 50/50 Glycol in October of every year. ( 4 e 9

A l REV.3 J j 1 i ? j l The purpose of this memo is to help explain why air conditionur capacity is reduced as enclosure tasape rature is. reduced, und to provide Marketing with a " rule-of-thumb" se to the extent of tho i. reduction. i As you know. McLean Midwest air conditioners are normally rated at i 125 r ambient and itS F enciumure return air temperatures. Typically, this condition imposes the highest load on the air. conditioner. The basic rulv tu ressembe r is that any re d.n e t i e ri in the return ai r j teenavature will e n u m., a c riqgtion in the emumeite or tlw air l conditioner, This tw because s reduction in the return Air temperature requires a reduc tion in the evaporator coil temperaturn, which in turn requires u l lower auction pressuro in the refrigeration system. A lower muction i pressure, in turn, reduces the density of Lse muction gas beinig pumped i by the compressor. Since the pumping capa::ity of the compressor is fixed by volume, this reduction in muetion gas density means that the coaspressor is pumping less weight of refrignemnt, With a corrouponding i loss in air conditioning capacit.y. I The less of sapscity with a reduction in suction pressure (or eneleaure return air temperature) is extre.ely rapid. For best capacity performance and operating officiency, it is important that the air conditioner operate at the highest suction pressure possible. A decrease in the ambians temperature will seult in un increase i s. air conditioner, capacity, due to the reduction of the head pressure, i However, this capacity increase is small compared to the loss ot' capacity due to the decramme in the auction pressure. For this i roamon. the not result-o f veriuc i tw both tne naibt.nt t e mrer ra t u re atut the enclosure return mir temonruture by t h a. m.- anunt sa n reduction in hir enhdi t i ott i n e e n ts n e s t y, I k i ' 4000 83rs menue ewin Dewe.m Pan siamnwevis SSee. f!;: :o t. n.eori. tvies *0-0 03. a Ast ec st SCO OW.
