1. OBJECTIVE The objective of this calculation is to determine the maximum ambient air temperature limits for operation of the Fort Calhoun Station Emergency Diesel Generators within the bounds of the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> deration curve.

2. METHODS 1 Determine the KW capacity of the diesel generator without considering the effects of elevated air temperature on jacket water temperature or turbocharger intake temperature.

2 Predict the turbocharger intake tempcrature at elevated conditions.

3 Predict jacket water temperatures at elevated conditions:

i. Determine fan flow rates at elevated temperatures.

ii. Compare fan flows to required flows to maintain jacket water at 190 *F and 208'F.

4 Determine deration factors from the predicted jacket water and turbocharger temperatures.

5 Compare derated power to post LOCA demands from calculation FC03382.

3. ASSUMPTIONS 1 Ambient air pressures are considered constant.

2 The diesels are in a cold shutdown condition with thejacket water at a temperature of 125 *F prior to the start of the accident. Test results indicate that the temperature is 120

• F at the time of start. This assumption is conservative.

3 Turbocharger inlet air temperature delta T with ambient air does not change dramatically with outside air temperature increases, ie. the outside air temperature to turbocharger intake delta T from 95'F ambient can be used to predict turbocharger intake temperature at 110* F ambient conditions.

4 The radiator fan intake is equivalent to outdoor temperature + 1 "F. This is validated by test data gathered during the last test performed on DG-2.

5 The maximum amount of emergency safeguards equipment started by SIAS is considered to be the required load for the diesels. Additional optional loads that may be desired to assist operations in accident response, such as station air compressors, I are not included in the required electrical load calculations. j 6 Although the new fans draw more air, the air flow in the room is such that the turbocharger inlet air temperature is assumed to be unaffected.

Calc FC05916 Rev 3 Page 7 Discussion:

DG-1 Above 10l*F ambient air temperature, DG-l's jacket water temperature is expected to exceed 190*F. Per conversations with Morrison Knudsen, the 200-210 curve must then be -

~

used for determining the deration factor. This accourits for approximately 7% reduction in diesel generator derated capacity, If the present turbocharger inlet temperatures predicted for this ambient air temperature condition are used while requiring the emergency load to be maintained less than the 2000 hr rating,110*F becomes the upper ambient air temperature limit for DG-1. Per figure 2 it can be seen that the estimated load does not

exceed the Diesel Generator 2000 hr rating. In addition significant margin exists if the event is initiated from the prewarmed condition (ie. JWOT at 125*F). If the event is initiated 2 immediately following a surveillance test and the diesel is already heated up to a steady state condition, the margin is 1 KW, This has been determined to be acceptable based on the conservatism associated with calculation FC03382 and the likelihood of event initiation during this period.

EA-FC-90-062 evaluates the ambient temperature limits based on generator rating and

] cooling temperatures as well as exciter cabinet cooling limits. The results of this EAjustify d

operation at 110*F.

' Previous revisions of this calculation resulted in a limiting ambient temperature of 107*.F.

This value has been revised based on the results of hot weather testing performed on July 11,1995 at 96*F.

l One identified method for achieving a higher limiting temperature is to replace the 50%

4 Ethylene Glycol / Water mixture with treated water which result in a higher heat removal rate. I Based on existing historical information it is not expected that these measures will be required.

1 Calc FC05916 Rev 3 Page 8 DG-2 Due to the load reduction performed during the 1992 Refueling outage, DG-2 is in a satisfactory configuration up to 115'F with 50% Ethylene Glycol / Water Mixture as a i

coolant media. Above 105'F ambient air temperature, DG-2's jacket water temperature is -

expected to exceed 190*F. Per conversations with Morrison Knudsen, the 200-210 curve must then be used for determining the deration factor. This accounts for approximately 7%

reduction in diesel generator derated capacity. Although the jacket water temperature exceeds 190*F it remains below 208'F in this temperature range. Because the demand was reduced on this diesel generator, the derated power, even with the 7% reduction based on thejacket water temperature, exceeds the most severe accident demand load.

EA-FC-90-062 evaluates the ambient temperature limits based on generator rating and cooling temperatures as well as exciter cabinet cooling limits. The results of this EAjustify operation at 114*F based on the rating of the generator and the associated cooling limits.

~

The ambient temperature limit associated with the exciter cabinet cooling was established

) at 110*F. This limit was based on a 9'F delta with the air conditioning unit operating at a i 50% duty cycle and 89'F room temperature. Based on the analytical method used for DG-1 cooling unit, the duty cycle for VA-759B is 67.2% with an ambient temp = 114*F, Room

! Temp. = 132*F. (50%+(132-89)*0.40) [ref. 4.11, Paragraph 6.12.3.1&2] This duty cycle I

is considered adequate to maintain the exciter cabinet within the required temperature range

(80*F to 122*F). Based on these results, the temperature limit for operation of DG-2 will be established at 114*F. The tables and figures associated with DG-2 will therefore be revised in revision 2 of this calculation to reflect an ambient temperature of 114*F.

Previous revisions of this calculation resulted in a limiting ambient temperature of 110

deg F. This value was increased based on the results of hot weather testing performed July j 12,1995 e. 99'F.

Instrument uncertainty Post test calibration was conducted on equipment used in gathering data 'for the July,1995 testing.

The results of these calibrations showed that the instrumentation used for temperature measurement

. during the testing were in error. Jacket water temperature readings used in the evaluation of this data (see tables 7 and 8) were adjusted to account for the instrument error. All other instrumentation was found to be accurate. No additional error corrections were made based on this information.

1 ILGd Turbo Inlet Temperature This temperature is based on the ambient air temperature. The differential temperature is determined using data from the July 11,1995 testing. The test results indicate that the initial inlet temperature is l'F above the outside temperature and increases to 5'F above over the first 50 minutes. The remainder of the test the 5"F differential was maintained. The temperatures between zero and fifty minutes were linearly interpolated.

JW Outlet Temperature This temperature is based on the ambient air temperature. The differential temperature is determined using data fmm the July 11,1995 testing. The test results indicate that the initial inlet teinperature is 120*F (125'F used, see assumption 3.2) and increases to 89'F above -

ambient over the first 10 minutes. The remainder of the test the 89"F differential was maintained. The temperatures between zero and 10 minutes were linearly interpolated. ]

Initial KW (2000 Hr)

The initial KW available is 2627 KW as previously calculated.

Initial KW (4 Hr)

The initial KW available is 2771KW as previously calculated.

Derate Factor

, The derating factor is determined based on the Turbocharger inlet temperature and the

engine coolant outlet temperature. (see Derating Curve attached)

! Demand KW I The demand KW value was taken from calculation FC03382 Rev 8 Margin j Margin is the derated KW available from the diesel minus the demand value.

determined using data from the July 12,1995 testing. The test results indicate that the initial inlet temperature is 2*F above the outside temperature and increases to 16* F above over the first 60 minutes. The remainder of the test the 16*F differential was maintained. The temperatures between zero and 60 minutes were linearly interpolated.

JW Outlet Temperature This temperature is based on the ambient air temperature. The differential temperature is determined using data from the July 12,1995 testing. The test results indicate that the initial inlet temperature is 120*F (125*F used, see assumption 3.b) and increases to 85'F above ambient over the first 30 minutes. The remainder of the test the temperature varied with load. Under the conditions of the emergency scenario the differential temperature would be less than 85*F due to the reduction ofload. A differential temperature of 85*F will be used in this calculation to be conservative. The temperatures between zero and 30 minutes were linearly interpolated.

Initial KW The initial KW available is 2627 KW as previously calculated.

Derate Factor The derating factor is determined based on the Turbocharger inlet temperature and the engine coolant outlet temperature. (see Derating Curve attached)

h On Marcn 16-and 18 1992, field measurements were performed to determine the power requirement of the' cooling fan at various blade pitch settings. The power is delivered to the fan by a-take-off shaft through a gear reducer. One end of the take-off shaft.is' coupled to the free end of the crankshaft of the Emergency Diesel Generator, the other end is coupled to a gear reducer. The Diesel engine is a General Motors Model 20-645-E4.

The. generator is rated at 3250 kVA.

The take-off shaft was instrumented using strain gages to serve as a torque transducer. Using radio telemetry, the torque signal was transmitted to a data acquisition system. Prior to the 1 tests, the entire measuring system was calibrated and to end by applying known torque inputs to the shaft and recording the

. output of the data acquisition system.

Tests were performed at 500 rpm and 900 rpm engine speeds and at four blade pitch settings ranging from 12 to 26 degrees. In each test, the data acquisition system recorded the torque measurements and using the known rotational speed of the take-off shaft computed the engine power delivered to the fan drive. The results obtained show good repeatability and are reliable. This is a factual report to present the test results.

2.0 CALIBRATION AND MEASUREMENT PROCEDURES The take-off shaft was instrumented with mental-foil strain gages arranged on the shaft in a manner to provide an output proportional to torsional strain and to be unaffected by bending or axial forces.

The following instrumentation was used in the tests:

Description Make & Model M&TE No. Calibration Due Date Strain Gages Micro-Measurement CEA-06-187UV-350, Strain Amplifier Vishay 2310 AMS02 10/02/92 Force Transducer HBM USB-500 LCOO9 04/30/93 Radio Transmitter PMD T-20/T-201 TELO7 CBU Radio Receiver.

The torque measurement system is. illustrated in Figure 1. An FM/FM radio transmitter equipped with strain gage conditioning circuitry was' mounted on the take-off shaft and connected to the strain sensors. The transmitted radio signal was captured and demodulated in a receiver. The receiver provided a voltage output proportional to the torsional strain in the shaft. That output was connected to a data acquisition card in a portable computer for quantitative measurement. A spectrum analyzer and an oscilloscope were used for monitoring the quality of the received signal and that of the receiver output respectively.

Both functions were qualitative. On command from the keyboard, the data acquisition was performed at a set sampling rate to obtain a desired number of data samples. The data collection parameters were preset in the data acquisition software to 2 samples /sec and 36 samples total for the static calibration and .

10 samples /sec and 310 samples total for the fan test.

The torque measuring system was calibrated end to end, treating the instrumented shaft, the telemetry and data acquisition equipment as one system. The coupling between the take-off shaft and the gear reducer driving the fan was broken, and a rigid i

r %7M n 2-

pago 3 lever arm was attached to'the coupling flange of the take-off shaft. The torque input to the shaft was applied by suspending dead weight from the end of the lever arm. The distance from the centerline of the shaft to the point of weight attachment, measured to reflect to effective moment arm, was 42.0". A precision force transducer was used as a link between the lever arm and the suspended dead weight and served to provide a -

precision measurement of the applied force. Figure 2 is a .

schematic illustration of the calibration set-up.

TheLoutput of the force measuring system was connected to a data acquisition channel. The force measuring system was also calibrated end-to-end. The calibration was performed using the precision' shunt method to' simulate'i'nput to the transducer and recording the output of the data acquisition system. The torque was applied in four increments up to 720 lb-ft, which was the

-anticipated torque range of the test. The actual maximum torque seen in the subsequent tests was 880 lb-ft. Both increasing and decreasing loads were applied. The output of the telemetry-based torque measuring system and that of the force measuring system were recorded simultaneously at'each load. The calibration procedure was performed twice. At the completion of the calibration, the data acquisition software combined the two sets of results to compute the input-output relationship of the torque '

measuring system. The calibration data are given in Table 1 and have been plotted in Figure 3.

Before each test, the pitch of the fan blades was adjusted to the desired angle and before the engine was started up a set of zero torque readings were recorded. The engine was brought up to 500 rpm'and then to 900 rpm and torque readings were taken. At each speed two to four sets of torque readings were taken. Taking the zero readings and the known engine. speed into account, the torque i

and power flowing through the take-off shaft were determined for each set of data. Tests were performed at blade pitch settings of 12, 18, 22 and 26 degrees.

3.0 TEST RESULTS i

The results of the torque measurements and the shaft power data j '

computed from them have been summarized in Table 2. Ir. Figure 4 the shaft power data have been plotted against blade pitch for both engine speeds.
