James A. FitzPatrick Nuclear Power Plant Response to RAI Questions
ATTACHMENT I to JAFP-08-0086 Questions from Component Performance and Testing Branch RAI Question:
- 1) "On Page 3 of 9 of Attachment 1, it is stated that "The fuel consumption calculation was performed assuming the worst parameter values allowed by the diesel'fuel oil sampling program." ULSD fuel can have an API gravity as high as 42. What API gravity value was used in your fuel consumption calculation?"
Response
Surveillance Requirement Bases 3.8.3.3 limits API gravity to 39 (range of 27 to 39). The JAF Fuel Oil Program requires sampling of fuel oil at the time of receipt. Portions of the fuel oil analysis are required to be complete prior to allowing fuel to be added to the fuel oil storage tanks. The test for API gravity is one of the initial acceptance tests, fuel oil with an API gravity greater that 39 would be rejected. Therefore, API gravity values of 27 - 39 were used in JAF-CALC-07-00020 Rev. 0.
RAI Question:
- 2) "On Page 5 of 9 of Attachment 1, it is stated that "The 7 day supply was calculated for API Gravity Values over the range allowed by ASTM-D975-95." Please provide a copy of ASTM-D975-95, indicating the specific location of the allowable API gravity range referenced."'
Response
The source of the API Gravity Range was misstated in Reference 1. Appendix C of ANSI/ANS-59.51 provides the API Gravity Range used as acceptance criteria for receiving fuel. This range is also specified in JAF's Technical Specification Bases for Surveillance Requirement 3.8.3.3.
RAI Question:
- 3) "Please submit your fuel consumption calculation and calculation JAF-CALC-07-00020, Revised Emergency Diesel Generator (EDG) Fuel Oil Storage Quantities for 7 Day and 6 Day Supplies."
Response
JAF-CALC-07-00020 Revision 0, "Revised Emergency Diesel Generator (EDG) Fuel Oil Storage Quantities for 7 Day and 6 Day Supplies" is supplied as Attachment 2 to this correspondence. This calculation includes the information related to fuel consumption.
Page 1 of 4
ATTACHMENT 1 to JAFP-08-0086 RAI Question:
- 4) "On Page 6 of 9 of Attachment 1, it is stated that "The specific volume of lube oil equivalent to a 7 and 6 day supply is based on'the Emergency Diesel Generator (EDG) manufacturer's consumption values for the run time of the EDG." Please confirm that these volumes are for a lube oil that the EDG manufacturer has confirmed is compatible with ULSD fuel."ý
Response
JAF has confirmed with EMD (the diesel engine manufacturer) that the lube oil in use at JAF is not affected by the use of ULSD fuel oil and the volume for a 7-day and 6-day supply is unchanged.
RAI Question:
- 5) "Tables B3.8.3-1 and B3.8.3-2 provide 7-day and 6-day (respectively) fuel oil storage tank quantities for API gravity values of 27, 30, 33, 36, and 39. If the API gravity of the fuel in a storage tank is in between these values or above 39, how are the 7-day and 6-day storage quantities determined?"
Response
The Diesel Fuel Oil Testing Program only allows acceptance of fuel oil with an API Gravity between 27 and 39. Therefore, the API gravity of fuel in the storage tankscannot exceed
.39. Linear interpolation of the information presented in Tables B3.8.3-1 and B3.8.3-2 will be used for determining fuel oil volumes when the actual API Gravity is between the values specified in the tables.
RAI Question:
- 6) "Surveillance Requirement 3.8.1.4 states "Verify each day tank contains 327 gal of fuel oil." Please confirm that the minimum quantity of 327 gallons pertains to ULSD fuel."
Response
The 327 gallons of fuel oil specified as acceptance criteria in SR 3.8.1.4 does pertain to ULSD fuel.

ATTACHMENT I to JAFP-08-0086 Questions from Steam Generator Tube Integrity and Chemical Engineering Branch RAI Question:
- 1) "2.0 Proposed Changes The licensee modified Surveillance Requirement (SR) 3.8.3.1 by changing the maximum amount of fuel in storage tank from volume (in gallons) to the amount required to operate the Emergency Diesel Generators for 7 days and have a 6-day supply in the storage tank. This modification required a revision to the bases of SR 3.8.3.1 by adding the volume equivalent of a 7-day supply, which is tabulated in B3.8.3-1 and was calculated using Regulatory Guide:(RG) 1.137, Rev. 1 (1979) ANIS/ANS-59.51-1997, and JAF-CALC-07-00020. The licensee is asked to [Please] describe the specific methods and procedures used for calculating these values."
Response
The specific methodology used in the calculation is documented in JAF-CALC-07-00020 Rev. 0 (Attachment 2).
RAI Question:
- 2) "TS 5.5.10 and 4.2 Diesel Fuel Oil Testing Program Currently, the standard test method for determining free water and particulate contamination in diesel fuel oil is the "Clear and. Bright Method" (ASTM D4176) providing "Iaclear and bright appearance with proper color". However, this method has several disadvantages: it produces only subjective pass/fail results and it cannot be used with fuel oil having low light transmission due to either large amount of contaminants, or tinting used to specify the fuel oil grade (amount of sulfur). In order to overcome these shortcomings, the licensee proposes to modify the procedure by including one of the two additional tests for determining water and sediment content: ASTM D1796 or D2709. The modified procedure "will have a clear and bright appearance with proper color or water and sediment content within limits."
Since the proposed procedure is more complex and requires additional testing, [Please provide the detailed information as to how the procedure would be implemented,] does the licensee plan to use the "Clear and Bright" method only when the anticipated contamination of fuel oil is low, and the modified procedure when the anticipated amount of the impurities is high?"
.Response:
JAF will continue to use the "Clear and Bright" Test method as the preferred test method during diesel fuel oil receipt testing. The water and sediment testing would be used as a back-up method when a clear and bright test cannot be performed. Since the water and sediment test is not currently an approved test method for JAF, the equipment and procedures necessary to perform the testing are not available. JAF will obtain the appropriate test equipment and develop the necessary procedural guidance as part of the implementation of this amendment if approved. As documented in Attachment 4 to this letter the development of a water and sediment testing procedure in accordance with ASTM-D1796 or ASTM-D2709 is a commitment.

- 3) "3.0 Background In the submittal the licensee made a statement implying that removal of sulfur and aromatics from the fuel oil will have an insignificant effect as long as the API gravity does not change significantly., The licensee is asked to [Please] provide the basis for this statement."
Response
The basis for the statement is documented in Calculation JAF-CALC-06-00114 Rev. 1 (Attachment 3).

Fuel Oil Storage quantities in light of the density (API gravity) and vortex critical submergence issues raised with CR-JAF-2007-02392 and CR-JAF-2007-02490. The basic method is similar to that used for the Operability Evaluations prepared for the related CRs except that a more appropriate critical submergence correlation has been e mployed (Attachment 1 provides a comparison of critical submergencecorrelations) and calculation JAF-CALC-07-00019 is used to determine unavailable volume.
Conclusion The following tabulated results for API Gravity values and limiting quantities (page 9) will be used to support the proposed Technical Specification amendment. At limiting fuel conditions (API:39) the new 7-day quantities are 33898, 34226, 34153 and 34197 gallons and the new 6-day quantities are 29260, 29588, 29515.and 29560 gallons for the A, B" C and D EDGs, respectively.

Entergy Nuclear JAF-CALC-07-00020, Rev. 0 Prepared by: P. Swinburne J.A. FitzPatrick N.P.P. Revised EDG Fuel Oil Storage Quantities for Reviewed by: D. Burch 7 Day and 6 Day Supplies Assumptions
- 1. Assume limiting fuel conditions per D 975 for S500 fuel. EC Markup 551 showed that at the same API gravity S500 (low sulfur fuel oil) actually had a slightly lower heat content than S15 (ultra low sulfur fuel oil). Limiting conditions means the maximum sulfur, ash and moisture/
sediment contents permitted by D 975 as these factors all tend to reduce heat content.
- 2. Assume a temperature of 590 F or 150 C for underground stored fuel. This is the reference temperature for density used in D 4868 and this is reasonable for underground tanks. At depths below four feet ground temperatures stay at a constant 50 to 55' F year-round so density at 590 F is conservative.
- 3. Assume that the ASTM D 4868 method provides a good method to determine heat content in lieu of specific calorimeter testing. The method is supported by the Fairbanks Morse Owners' Group report (input 8).
Method of Analysis This analysis will determine 7 day and 6 day gross volume of EDG diesel fuel based on API gravity with S500 (low sulfur diesel) fuel. The limiting sulfur content for S500 will be used as a conservatism since it will be a long time before existing sulfur levels are diluted to the S1 5 limit. The unusable fuel oil tank volumewill include a vortex prevention submergence using the Chang 1979 correlation (as presented by Knauss). The unusable tank volume will be determined from calculation JAF-CALC-07-00019. The day tank volume will not be credited since the new Technical Specification requires that the entire 7 or 6 day supply be located within the underground storage tanks. The ASTM D 4868 method for heat content estimation will be used but will also include a 95% confidence interval (0.35 MJ/kg). The vendor provided specific fuel consumption curve (EMD 20-645 E4) will be used as basis for fuel consumption rate.

Burch 7 Day and 6 Day Supplies Note that the water and sediment is reported as percent volume vs. percent weight for D4868 thus divided by SG to correct (water has greater density so weight percentage will be greater than volume percentage). This correction effectively considers that the specific gravity of the water and sediment fraction is 1. While this will be true for water "sediment" may have a higher specific gravity. Since the fraction of both water and sediment is generally very low (usually much less than D 975 limit) this is reasonable.

Density (d) in D4868 is at 15' C or 590 F. From Crane 410, A-7 graph there is an approximate 3.9% increase in specific gravity or density for a 100 F° temperature decrease (applies between 0' F and 1000 F). Thus the increase in density from 60' F to 59' F (150 C) is given by..

Entergy Nuclear Critical Submergence Correlation Attachment 1 to J.A. FitzPatrick N.P.P. Comparison JAF-CALC-07-00020 Required submergence to prevent air-entraining vortex formation as a function of flow velocity can be determined using a number of methods.

The testing supporting this limit was done with a 24" nominal diameter suction pipe with flow rates between 3000 gpm and 12000 gpm and submergences of 2 ft, 3.5 ft and 5 ft. This corresponds to Froude numbers between 0.29 and 1.15 when pipe diameter is used as the defining length.

To allow comparison between the correlations, the Reddy-Pickford definition sketch is chosen to provide common definitions. Furthermore, the Froude number used in all of the equivalent correlations will use pipe diameter as the length dimension. Using this sketch, the correlations can be transformed to yieldexpressions to determine equivalent critical submergences to allow direct comparison of the correlations.

Comparison JAF-CALC-07-00020 Comparing the Sanders et al. and Reddy-Pickford definition sketches, the submergence in Sanders is equivalent to the submergence in Reddy-Pickford plus one pipe diameter. The transformation is then made as follows:
c2 S = cl(Fr) 2 2
H = D.cl(Fr) 2 s + d = d-cl(Fr)c ScS(v) = d- cI(Fr(v))2 1) where c1=2.087, c 2=0.670 when 0 <= Fr <= 0.35 and c 1=1.363, c2 =0.261 when 0.35 <= Fr <= 1.40:

Conclusion:
While either the correlations of Sanders, et al., or that derived from NUREG/CR-2772 allow less submergence over a suction before air-entraining vortices form, it is questionable whether they provide reasonable results for the EDG fuel oil storage tank suctions and should not be used for the purpose of determining required submergence. This conclusion is based on the lack of geometric similarity compounded by flow conditions.for which viscous, forces may require consideration. While the question of whether viscous forces could affect the result are also S.. applicable to the correlation presented in Knauss for suctions oriented vertically upwardit is the best available information and should be used to evaluate the potential for formation of-;:
air-entraining vortices at the EDG fuel oil suctions. The required submergence at the suctioh using the correlation from Knauss is:

API gravity eP us provideifree content t6 the,orld by donating From Wikipedia, the free encyclopedia The American Petroleum Institute gravity, or APIgravity, is a measure of how heavy or light a petroleum liquid is compared to water. If its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API gravity is thus a measure of the relative density of a petroleum liquid and the density of water, but it is used to compare the relative densities of petroleum liquids. For example, if one petroleum liquid floats on another and is therefore less dense, it has a greater API gravity. Although mathematically API gravity has no units (see the formula below), it is nevertheless referred to as being in "degrees". API gravity is graduated in degrees on a hydrometer instrument and was designed so that most values would fall between 10 and 70 API gravity degrees.
Contents 1History of development 2 API gravity formulas 3 Classifications or grades
- 4 External links History of development.
'The U.S. National Bureau of Standards in 1916 established the Baum6 scale (see degrees Baum6) as the standard for measuring specific gravity of liquids less dense than water. Investigation by the U.S.
National Academy of Sciences found major errors in salinity and temperature controls that had caused serious variations in published values. Hydrometers in the U.S. had been manufactured and distributed widely with a modulus of 141.5 instead of the Baum6 scale modulus of 140. The scale was so firmly established that by 1921 the remedy, implemented by the American Petroleum Institute was to create the API Gravity scale recognizing the scale that was actually being used.
API gravity formulas The formula used to obtain the API gravity of petroleum liquids is thus:
141.5 API gravity - at 60'F - 131.5 SG Conversely, the specific gravity of petroleum liquids can be derived from the API gravity value as SG at 60 0F-141.5 APIGravity + 131.5 (Further tables give adjustments for temperature).
(See ASTM D1298) http://en.wikipedia.org/wiki/APIgravity 9/20/2007
API gravity - Wikipedia, the free encyclopedia Page 2 of 3
- 7-r'9c,*i,," 3 Y*F-cL-o7- oOO Thus, a heavy oil with a specific gravity of 1.0 (i.e., with the same density as pure water at 60'F) would have an API gravity of:
141.5 131.5 = 10.0 degrees API.
1.0 Classifications or grades Generally speaking 40 to 45 API gravity degree oils have a greatest commercial price and values outside this range have lower commercial Price. Above 45 degrees API gravity the molecular chains become shorter and less valuable to a refinery.
(
Crude oil is classified as light, medium or heavy, according to its measured API gravity.
Light crude oil is defined as having an API gravity higher than 31.1 'API Medium oil is defined as having an API gravity between 22.3 0API and 31.1 'API Heavy oil is defined as having an API gravity below.22.3 AJPI.
Not all parties use the same grading.[l] (http://www.crudemonitor.ca/quickfacts/miscigrades.pdf) The
$JS Geological Society uses slightly different definitions at [2]
. .(http://pubs.usgs.gov/fs/2006/3133/pdf/FS2006-3133 508.pdf) Simply put, bitumeri, sihksin fresh-water, while oil floats.
Oil which will not flow at normal temperatures or without dilution is named bitumen and the API gravity is generally less than 10 °API. Bitumen derived from the oil sands deposits in the Alberta, Canada area has an API gravity of around 8 'API. It is 'upgraded' to an API gravity of 31 °API to 33 0 API and the upgraded oil is knownas synthetic crude.

Entergy Nuclear JAF-CALC-06-00114 Rev. 1 (EC 551) Prepared by: P. Swinburne J.A. FitzPatrick N.P.P. EC Markup Reviewed by: T. Andersen PURPOSE The purpose of this EC Markup is to replace the 4.5% assumed heat content reduction of calculation JAF-CALC-06-00114 with analysis using ASTM D4868 to show that at the same API gravity, there is no degradation in volumetric heat content associated with a change from low sulfur (S500) to ultra low sulfur (S15) fuel. Technical Specification Bases for SR 3.8.3.3 stipulates an API gravity range at 60 F from 27 degrees to 39 degrees. Thus any change in API gravity (density) associated with a change from S500 to S15 EDG fuel oil will be bounded by existing Technical Specification requirements. The acceptablity of the present Technical Specification EDG Fuel Oil Storage requirements with the permitted API gravity range will be addressed with response to CR-JAF-2007-02392.

Entergy Nuclear JAF-CALC-06-00114 Rev. 1 (EC 551) Prepared by: P. Swinburne J.A. FitzPatrick N.P.P. EC Markup Reviewed by: T. Andersen Density (d) in D4868 is at 150 C or 59' F. From Crane 410, A-7 graph there is an approximate 3.9% increase in specific gravity or density for a 100 F° temperature decrease (applies between 00 F and 1000 F). Thus the increase in density from 600 F to 590 F (15° C) is given by..

When adjusted for API gravity there is virtually no change in heat content associated with a change from S500 to ULSD (S15) fuel. It is incorrect to compare fuels with different API gravity readings and associate a loss of volume based heat content on the change is sulfur content. The primary source of difference is the typical change.in API gravity.
