ATTACHMENT 1 Supplemental Information for Request for License Amendment to Dresden Nuclear Power Station Technical Specification 3.8.1, "AC Sources - Operating" Following are the NRC's requests in bold italicized font, followed by Exelon Generation Company, LLC's (EGC's) responses.

RA/ EPNB-1:

On Page 4 of Attachment 1 to the license amendment request (LAR), the licensee states that "Ultra Low Sulfur Fuel Oil (ULSD) has been in use at DNPS since 2007; therefore, this confirmation of fuel oil consumption rates also accounts for the use of ULSD." ASTM D 975, "Standard Specification for Diesel Fuel Oils," allows for up to 5 percent biodiese/ in the fuel oil without labeling.

Discuss whether or not the actual fuel oil consumption rate, and the fuel oil consumption rate curve provided by the manufacturer, take into account up to 5 percent biodiesel allowed by ASTM D 975. If fuel oil is received without biodiese/

at DNPS, explain how that is ensured.

Exelon Generation Company. LLC CEGC) Response:

At Dresden Nuclear Power Station (DNPS), Units 2 and 3, new diesel fuel oil for the diesel generators (DGs) is tested in accordance with ASTM D7371-07, "Standard Test Method for Determination of Biodiesel (Fatty Acid Methyl Esters) Content in Diesel Fuel Oil Using Mid Infrared Spectroscopy ([Fourier Transform Infrared Spectroscopy] FTIR-ATR-PLS Method)," to verify the bio-diesel content is less than(<) 0.1 %.

While the actual fuel oil consumption rates as determined by surveillance tests, and the fuel oil consumption rate curve provided by the manufacturer do not take into account the effects of up to five (5) percent (%) biodiesel allowed by ASTM D 975, the biodiesel content in diesel fuel oil utilized at DNPS, Units 2 and 3 is controlled to be <0.1 %. This assures that there will no appreciable effects from biodiesel fuel oil on DNPS DG performance, including engine power and fuel oil consumption rates. Sample results for biodiesel are required within 31 days. If new fuel oil sample results are found to be outside of biodiesel acceptance criteria, DNPS stored fuel oil will be restored to within limits in accordance with DNPS Chemistry Department procedures.

RA/ EPNB-2:

On Page 4 of Attachment 1 to the LAR, it is stated that Table 1, "Comparison of Volumetric Gross Heat Content at American Petroleum Institute (AP/) Gravities of 32 and 39," demonstrates the relationship of volumetric gross heat to AP/ gravity.

For the gross heat values in Table 1, discuss how the use of ULSD is factored into the gross heat values in the table.

EGC Response:

EGC has utilized ultra low sulfur diesel fuel oil (ULSD) for the DNPS, Units 2 and 3 DGs since 2007. Fuel oil test results for ULSD samples gathered across the EGC nuclear Page 1of4

ATTACHMENT 1 Supplemental Information for Request for License Amendment to Dresden Nuclear Power Station Technical Specification 3.8.1 , "AC Sources - Operating" fleet over a three-year period is shown in Figure 1 below. The heating values of typical diesel fuel published by the National Bureau of Standards (NBS) in Miscellaneous Publication No. 97 , "Thermal Properties of Petroleum Products," in 1933 have also been plotted for visual comparison.

30 35 40 45 API Gravity Figure 1: HHV of ULSD Fuel Oil Samples from Across the EGC Fleet The collected ULSD gross heat content data showed some variations for the similar American Petroleum Institute (API) gravity. The data scatter is likely due to differences in base oil stock and refining processes among fuel oil refineries , as well as testing inaccuracies. This data validates the claim that the heat content of ULSD fuel is only marginally different than that of the fuels with higher sulfur content. The data shows the heat values of the ULSD fuel correlates very well with S500 (i.e. , legacy fuel oil with a maximum sulfur content of 500 parts per million by weight) fuel oil of similar API gravity, and is about 1 % lower when compared to heat values published in NBS Publication No. 97 . This is consistent with the literature published by Marathon, Chevron , and the API that report that ULSD is expected to have approximately a 1% lower British Thermal Unit (BTU) per gallon heat content when compared to S500 fuel.

The heating values shown in Table 1 of the license amendment request (LAR) are based solely on typical S500 fuel oil as published in the NBS Miscellaneous Publication No. 97 .

As such , the gross heat values in Table 1 would be approximately 1% lower for ULSD.

Further, as discussed in the LAR, the actual fuel consumption rates for the DNPS DGs are determined from surveillance testing and are based on the ULSD fuel used at DNPS.

Page 2 of 4

ATTACHMENT 1 Supplemental Information for Request for License Amendment to Dresden Nuclear Power Station Technical Specification 3.8.1, "AC Sources - Operating" Acceptance tests have shown the fuel oil received at Dresden has API gravity (@60°F) values of 32 to 34, and the station fuel oil test acceptance criteria have an API range greater than or equal to(<::) 27 and less than or equal to (S) 39. The information in Table 1 is used to conservatively adjust the observed fuel consumption rates which are based on an API gravity of 32 to an API gravity of 39 due to the difference in the gross heat values.

RAJ EPNB-3:

On Page 5 of Attachment 1 to the LAR, the licensee states that "the fuel oil consumption rate provided by the [diesel generator] DG engine manufacturer adequately covers the fuel consumption for the Unit 2, Unit 3, and Unit 213 DGs over the range of AP/ gravity values allowed by the Dresden Diesel Fuel Oil Testing Program."

Provide the related manufacturers engine data which supports the fuel oil consumption rate being adequate for the DNPS DGs for the range of AP/ gravity values allowed by DNPS Diesel Fuel Oil Testing Program.

EGC Response:

A copy of the fuel oil consumption rate curve provided by the manufacturer of the DNPS DGs is included as Figure 2 below. Fuel consumption rates for DG output greater than that shown on the curve were linearly interpolated. Fuel oil consumption rates from surveillance tests are conservatively adjusted based on API gravity and compared to the manufacturer's fuel oil consumption rate curve to verify that the manufacturer's curve continues to bound actual EOG fuel oil consumption rates.

This includes the impact of a potentially higher fuel consumption rate (from the use of fuel oil at the maximum allowable API gravity (lowest density) and if the EDGs operate at a 2% higher frequency, as allowed by the Tech Spec tolerance on EOG frequency. The calculation of the time the EDGs will run at 50% load was removed since this is no longer described in the Tech Spec Bases.

Revision 03 of this calculation is to evaluate the fuel consumption with the EDGs operating at 110%

rating and at frequency of 60.5 Hz (Ref. 4.13) or 61.2 Hz (Ref. 4.12). This is to address an NRC inspection finding (Ref. 4.14) .

2.1 Technical Specification Surveillance Requirement (SR) 3.B.1.4 (Reference 4.1) requires each day tank contains greater than or equal to 205 gallons of fuel oil and each bulk fuel storage tank contains greater than or equal to 10,000 gallons of fuel oil.

2.2 The bases for Tech Spec SR 3.B.1.4 are to: a) ensure adequate fuel oil in the day tank for a minimum of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of DG operation at full load plus 10%, and b) ensure adequate fuel oil in the bulk fuel storage tank*for approximately 2 days at full load (Reference 4.2}.

2.3 New fuel oil samples must have an API gravity at 60°F of~ 27 and s 39 (Reference 4.3) 2.4 SR 3.8.1.8 (Reference 4.12) requires the EDG to maintain steady state frequency;:: 58.8 Hz and s 61.2 Hz. Ttiis represents a tolerance of+/- 2% from the base frequency of 60 Hz.

The methodology to determine the operating time consists of dividing the available volume by the fuel consumption rate.

The pump affinity laws are used to adjust the pump power to account for the increase in EOG frequency (speed) because the Tech Spec tolerance of +2%. Pump affinity laws (see page 14-23 of Reference 4.7) state that pump power (P) is proportional to the cube of the pump speed (N):

P1/P2 = N1 3/Nl The methodology to determine if margin is available to accommodate the lower heating value of fuel with an API gravity of 39 consists of comparing the margin between actual fuel consumption rates as determined during plant surveillances and fuel consumption rates stated in the UFSAR to the margin reduction from using a fuel with an API gravity at the Tech Spec minimum of 39.

EDG fuel oil consumption rates are discussed in UFSAR Section 9.5.1 and UFSAR Figure 9.5-3 shows diesel fuel consumption versus load. At the 10% overload condition (2860 kW) each DG will consume 205 gallons of fuel per hour; at a rated load of 2600 kW, each DG wlll consLir:rir;:t 192 gaVhr, and at 50%

rated load, 105 gal/hr.

Day Tank Surveillance procedure DOS 6600-14 (Reference 4.5) has an acceptance criterion to ensure that 350 gallons or more remains in the day tank when the low level alarm is received. 350 gallons Is very conservative compared to Tech Spec SR 3.8.1.4 requirement of> 205 gallons in the day tank. The 145 gallons or 71 % margin is sufficient to accommodate a +2o/o frequency tolerance of the EDGs, if the frequency tolerance is interpreted as applicable to this SR.

The fuel consumption rate with the EDGs at 110% rated loading and at 60.5 Hz or 61.2 Hz is evaluated in Attachment E Bulk Fuel Oil Tank The pump affinity laws are used to adjust the pump power to account for the increase in EOG frequency (speed} because the Tech Spec tolerance of +2%. Pump affinity laws (see page 14-23 of Reference 4. 7) state that pump power (P) is proportional to the cube of the pump speed (N):

P1/P2 = N, 3/Nl Therefore, if the pump speed increases by 2% (N2 =1.02

  • N,), then pump power increases by 6.1 %

(P2 = 1.061 " P1).

Multiplying the rated EOG load of 2600 kW by 1.061 yields 2,759 kW ..

The fuel consumption with the EDGs at rated loading and at 60.5 Hz or 61.2 Hz is evaluated in Attachment E.

  • This data point 1s an outlier and 1s not included m the average to ensure the results are conseivatlve for the purposes of this calculation One purpose of the test Is to demonstrate that the'tuel oil day tank has sufficient capacity remaining at the low-level alarm setpoint to run the diesel at 110% for one hour before the fuel supply in the day tank is exhausted. DOS 6600-14 also has an acceptance criterion of verifying a minimum of 350 gallons of fuel remains in the day tank when the low level alarm Is received. 350 gallons is conservative compared to the acceptance criterion In Tech Spec SR 3.8.1.4 of >205 gallons in the day tank.

The results in the above table show a 4.5% or higher margin between the fuel consumption rate average measured during DOS 6600-14 surveillances (for both the average of the last two and last five suiveillances) and the nominal fuel consumption rate from UFSAR Figure 9.5-3.

The transition to ULSD fuel oil began in 2007. There is no discernible increase in fuel oil consumption after this date.

The diesel fuel oil in the EOG bulk fuel oil tanks is sampled monthly per DOS 0040-02 under pre-defines PMRQ 11845-03 (U2}, 370-02 (U2/3), and 5976-04 (U3) to comply with the Diesel Fuel Oil Testing Program and the results are sent to a laboratory for analysis. The results are trended by the EOG System Engineer. The results since 2007 are provided in Attachments B, C, and D.

There is no vendor information available to substantiate the API gravity of the fuel oil that was used to make UFSAR Figure 9.5-3. Therefore, the average fuel consumption rate and average API gravity during the last two fuel consumption rate surveillances will be used. The high heating values (HHVs) were obtained from a linear interpolation of the values In Attachment A.

With the EOG operating continuously at 11 Oo/o overload at with 60.5 Hz or 61.2 Hz, the fuel consumption rate of 208 gallons/hr or 211 gallons/hr is not bounded by the current Tech Spec SR 3.8.1.4 minimum requirement of 205 gallons in the day tank.

The fuel consumption rates averaged over the past 2 and 5 surveillances show a 4.5% or higher margin to the nominal fuel consumption rate from UFSAR Figure 9.5-3. The percent reduction in the HHV between the average API gravity of the fuel oil used since the beginning of 2007 and the HHV of fuel oil with an API gravity of 39 is 2.7% or less. Therefore, there is margin to accommodate the lower HHV of fuel oil at the Tech Spec minimum API gravity of 39. To ensure margin remains, the Diesel System Engineer has changed the upper API gravity limit from 39 to 34. If the API gravity trends above 34, then the System Engineer will generate an Issue Report for further evaluation.

Revision 8 Analysis No. 10553-CALC-07 Revision 003A Page 15 of 15 ATTACHMENT E EOG Fuel consumption at 60.5 Hz:

110% EDG loading= 2860 kW At 60.5 Hz, the EDG is operating at (60.5 Hz/60 Hz)+ 0 .83% of the nominal frequency Using the pump affinity laws, the EDG loading is proportional to the cube of the speed EDG _loading =2860kW x (1.0083) 3 = 2932kW From UFSAR Figure 9.5-3, the fuel consumption rate at 2932 kW is approximately 208 gallons/hr.

Tech Spec SR 3.8.1.4 (Ref. 4 . 1) is to verify that the fuel storage tank contains adequate inventory of fuel oil to support the EDG operation for approximately 2 days at full load.

EDG full loading = 2600 kW At 60.5 Hz EDG _loading = 2600k W x (1.0083) 3 =2666kW From UFSAR Figure 9.5-3, the fuel consumption rate at 2666 kW is approximately 197 gallons/hr.

Total fuel consumption for 2 days= (208 gallons/hr x 1 hr)+ (197 gallons/hr x 47 hrs)= 9467 gallons.

EDG Fuel consumption at 61.2 Hz:

110% EDG loading= 2860 kW At 61.2 Hz, the EDG is operating at (61.2 Hz/60 Hz)+ 2% of the nominal frequency Using the pump affinity laws, the EDG loading is proportional to the cube of the speed EDG _loadirig == 2860kW x(l.02) 3 =3035kW From UFSAR Figure 9.5-3, the fuel consumption rate at 3035 kW is approximately 211 gallons/hr.

EDG full loading =2600 kW At 61.2 Hz EDG _loading =2600kW x (1.02) 3 = 2759kW From UFSAR Figure 9 .5-3, the fuel consumption rate at 2759 kW is approximately 202 gallons/hr.

Total fuel consumption for 2 days= (211 gallons/hr x l hr)+ (202 gallons/hr x 47 hrs)= 9705 gallons.

Note the total fuel consumption is very conservative since it is based on the EDG operating at 60.5 or 61.2 Hz for the entire 2 day period.
