==SUMMARY==

The purpose of this report is to document the results of the testing of Surveillance Capsule V from the Joseph M. Farley Unit 2 nuclear power plant. Capsule V was removed at the end of cycle (EOC) 18 and post-irradiation mechanical tests of the Charpy V-notch and tensile specimens were performed. A fluence evaluation utilizing the recently released neutron transport and dosimetry cross-section libraries was derived from the ENDF/B-VI data-base. Capsule V received a fluence of 8.73E+19 n/cm 2 after 21.82 Effective Fuel Power Years (EFPY) of plant operation. The peak clad/base metal interface vessel fluence after 21.82 EFPY of plant operation was 2.43E+ 19 n/cm2 .
This evaluation concluded the following:
: 1.       The measured 30 ft-lb shift in transition temperature values of the plate material contained in Capsule V (longitudinal and transverse orientations) is less than the Regulatory Guide 1.99, Revision 2, predictions.
: 2.       The measured 30 ft-lb shift in transition temperature value of the weld metal contained in Capsule V is less than the Regulatory Guide 1.99, Revision 2, prediction.
: 3.       The measured percent decrease in upper shelf energy (USE) for all the plate and weld surveillance materials in Capsule V are less than the Regulatory 1.99, Revision 2, predictions.
: 4.       The beltline materials exhibit a more than adequate USE level for continued safe plant operation and are predicted to maintain an upper shelf energy greater than 50 ft-lb throughout the life of the vessel (54 EFPY) as required by 10CFR50, Appendix G.
: 5.       The surveillance weld data was found to be not credible, while the surveillance plate data was found to be credible. This evaluation can be found in Appendix D.
: 6.       The service period of applicability for the Pressure-Temperature Limit Curves labeled for 33.8 EFPY in WCAP-14689, Revision 4, must be reduced to account for the updated neutron fluence projections and vessel material chemistry factors calculated as part of the Surveillance Capsule V analysis. The new service period for these Pressure-Temperature Limit Curves is 32.8 EFPY.
Lastly, a brief summary of the Charpy V-notch testing can be found in Section 5.0. All Charpy V-notch data was plotted using a symmetric hyperbolic tangent curve fitting program.

==SUMMARY==
OF RESULTS The analysis of the reactor vessel materials contained in Surveillance Capsule V, the sixth and final capsule removed and tested from the Joseph M. Farley Unit 2 reactor pressure vessel, led to the following conclusions:
Capsule V received an average, fast neutron fluence (E> 1.0 MeV) of 8.73E+19 n/cm 2 after 21.82 EFPY of plant operation.
Irradiation of the reactor vessel intermediate shell plate B7212-1 Charpy specimens, oriented with the longitudinal axis of the specimen parallel to the major working direction (longitudinal orientation), resulted in an irradiated 30 ft-lb transition temperature of 196.0&deg;F and an irradiated 50 ft-lb transition temperature of 240.1 F. This results in a 30 ft-lb transition temperature increase of 218.3'F and a 50 ft-lb transition temperature increase of 230. 1F for the longitudinal orientation specimens. See Table 5-9.
Irradiation of the reactor vessel intermediate shell plate B7212-1 Charpy specimens, oriented with the longitudinal axis of the specimen perpendicular to the major working direction (transverse orientation), resulted in an irradiated 30 ft-lb transition temperature of 207.8&deg;F and an irradiated 50 ft-lb transition temperature of 234.37F. This results in a 30 ft-lb transition temperature increase of 215.3&deg;F and a 50 ft-lb transition temperature increase of 200.7&deg;F for the transverse orientation specimens. See Table 5-9.
Irradiation of the surveillance weld metal Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 22.0&deg;F and an irradiated 50 ft-lb transition temperature of 61.8&deg;F. This results in a 30 ft-lb transition temperature increase of 56.5&deg;F and a 50 ft-lb transition temperature increase of 77.2&deg;F. See Table 5-9.
Irradiation of the weld heat-affected-zone (HAZ) metal Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 26.2&deg;F and an irradiated 50 ft-lb transition temperature of 52.4&deg;F. This results in a 30 ft-lb transition temperature increase of 322.4&deg;F and a 50 ft-lb transition temperature increase of 257.7&deg;F. See Table 5-9.
The average USE of the intermediate shell plate B7212-1 Charpy specimens (longitudinal orientation) resulted in an average energy decrease of 44 ft-lb after irradiation. This results in an irradiated average USE of 86 ft-lb for the longitudinal orientation specimens. See Table 5-9.
The average USE of the intermediate shell plate B7212-1 Charpy specimens (transverse orientation) resulted in an average energy decrease of 26 ft-lb after irradiation. This results in an irradiated average USE of 69 ft-lb for the transverse orientation specimens. See Table 5-9.
The average USE of the surveillance weld metal Charpy specimens resulted in an average energy decrease of 20 ft-lb after irradiation. This results in an irradiated average USE of 124 ft-lb for the weld metal specimens. See Table 5-9.
WCAP-16918-NP                                                                                        April 2008 Revision 1

1-2 The average USE of the weld HAZ metal Charpy specimens resulted in an average energy decrease of 40 ft-lb after irradiation. This results in an irradiated average USE of 118 ft-lb for the weld HAZ metal. See Table 5-9.
A comparison, as presented in Table 5-10, of the Farley Unit 2 reactor vessel surveillance material test results with the Regulatory Guide 1.99, Revision 2113 predictions led to the following conclusions:
        -       The measured 30 ft-lb shift in transition temperature values of the intermediate shell plate B7212-1 specimens contained inCapsule V (longitudinal and transverse orientations) are less than the Regulatory Guide 1.99, Revision 2E3, predictions.
        -       The measured 30 ft-lb shift in transition temperature value of the surveillance weld metal specimens contained in Capsule V is less than the Regulatory Guide 1.99, Revision 2El3, prediction.
        -       The measured percent decrease in Upper Shelf Energy (USE) for all the plate and weld surveillance materials in Capsule V are less than the Regulatory 1.99, Revision 2E[l, predictions.
The calculated end-of-license (54 EFPY) neutron fluence (E> 1.0 MeV) at the core midplane for the Joseph M. Farley Unit 2 reactor vessel using the Regulatory Guide 1.99, Revision 2[1I attenuation formula (i.e., Equation #3 in the guide) are as follows:
2 Calculated:     Vessel inner radius*    =5.76E+19 n/cm 2
Vessel 1/4 thickness    = 3.59E+19 n/cm Vessel 3/4 thickness    = 1.40E+19 n/cm 2
                *Clad/base metal interface (From Table 6-2).
All beltline materials are expected to have an USE greater than 50 ft-lb through end of license (EOL, 54 EFPY) as required by 10CFR50, Appendix G[21.
The service period of applicability for the Pressure-Temperature Limit Curves labeled for 33.8 EFPY in WCAP-14689, Revision 4[3], must be reduced to account for the updated neutron fluence projections and vessel material chemistry factors calculated as part of the Surveillance Capsule V analysis. The new service period for these Pressure-Temperature Limit Curves is 32.8 EFPY.

2-1 2         INTRODUCTION This report presents the results of the examination of Capsule V, the sixth and final capsule removed from the reactor, as part of Southern Nuclear Operating Company's surveillance program for monitoring the effects of neutron irradiation on the Joseph M. Farley Unit 2 reactor pressure vessel materials under actual operating conditions.
The surveillance program for the Farley Unit 2 Nuclear Plant reactor pressure vessel materials was designed and recommended by the Westinghouse Electric Corporation. A description of the surveillance program and the pre-irradiation mechanical properties of the reactor vessel materials are presented in WCAP-8956, "Alabama Power Company Joseph M. Farley Nuclear Plant Unit No. 2 Reactor Vessel Radiation Surveillance Program''143. The surveillance program was planned to cover the 40-year design life of the reactor pressure vessel and was based on ASTM E185-73, "Standard Recommended Practice for Surveillance Tests for Nuclear Reactor Vessels"'51 . Capsule V was removed from the reactor after 21.82 EFPY of exposure and shipped to the remote metallographic facility (RMF) at the Westinghouse science and technology department (STD), where the post-irradiation mechanical testing of the Charpy V-notch impact and tensile surveillance specimens was performed.
This report summarizes the testing of and the post-irradiation data obtained from Surveillance Capsule V removed from the Southern Nuclear Operating Company Farley Unit 2 reactor vessel and discusses the analysis of the data.

3-1 3         BACKGROUND The ability of the large steel pressure vessel containing the reactor core and its primary coolant to resist fracture constitutes an important factor in ensuring safety in the nuclear industry. The beltline region of the reactor pressure vessel is the most critical region of the vessel because it is subjected to significant fast neutron bombardment. The overall effects of fast neutron irradiation on the mechanical properties of low alloy, ferritic pressure vessel steels such as SA533 Grade B Class 1 (base material of the Farley Unit 2 reactor pressure vessel beltline) are well documented in the literature. Generally, low alloy ferritic materials show an increase in hardness and tensile properties and a decrease in ductility and toughness during high-energy irradiation.
A method for ensuring the integrity of reactor pressure vessels has been presented in "Fracture Toughness Criteria for Protection Against Failure," Appendix G to Section XI of the ASME Boiler and Pressure Vessel Code16 3. The method uses fracture mechanics concepts and is based on the reference nil-ductility transition temperature (RTNDT).
RTNDT   is defined as the greater of either the drop weight nil-ductility transition temperature (NDTT per ASTM E208[7') or the temperature 60'F less than the 50 ft-lb (and 35-mil lateral expansion) temperature as determined from Charpy specimens oriented perpendicular (transverse) to the major working direction of the plate. The RTNDT of a given material is used to index that material to a reference stress intensity factor curve (Kic curve) which appears in Appendix G to the ASME Code[63. The Klc curve is a lower bound of static fracture toughness results obtained from several heats of pressure vessel steel. When a given material is indexed to the K1c curve, allowable stress intensity factors can be obtained for this material as a function of temperature. Allowable operating limits can then be determined using these allowable stress intensity factors.
RTNDT   and, in turn, the operating limits of nuclear power plants can be adjusted to account for the effects of radiation on the reactor vessel material properties. The changes in mechanical properties of a given reactor pressure vessel steel, due to irradiation, can be monitored by a reactor vessel surveillance program, such as the Farley Unit 2 reactor vessel radiation surveillance program 4 ], in which a surveillance capsule is periodically removed from the operating nuclear reactor and the encapsulated specimens tested. The increase in the average Charpy V-notch 30 ft-lb temperature (ARTNDT) due to irradiation is added to the initial RTNDT, along with a margin (M) to cover uncertainties, to adjust the RTNDT (ART) for radiation embrittlement. This ART (RTNDT initial + M + ARTNDT) is used to index the material to the K1 , curve and, in turn, to set operating limits for the nuclear power plant that take into account the effects of irradiation on the reactor vessel materials.

4-1 4        DESCRIPTION OF PROGRAM Six surveillance capsules for monitoring the effects of neutron exposure on the Farley Unit 2 reactor pressure vessel core region (beltline) materials were inserted in the reactor vessel prior to initial plant start-up. The six capsules were positioned in the reactor vessel between the neutron pads and the vessel wall as shown in Figure 4-1. The vertical center of the capsules is opposite the vertical center of the core.
Capsule V was removed after 21.82 EFPY of plant operation. This capsule contained Charpy V-notch, tensile, and 1/2T-compact tension (CT) fracture mechanics specimens made from intermediate shell plate B7212-1 (Heat #C7466-1) and manual metal arc weld metal identical to intermediate shell longitudinal weld seam 19-923B (Heat #BOLA). In addition, this capsule contained Charpy V-notch specimens from the weld heat-affected zone (HAZ) metal of intermediate shell plate B7212-l and pre-cracked bend bar specimens from intermediate shell plate B7212-1.
Test material obtained from intermediate shell plate B7212-1 (after the thermal heat treatment and forming of the plate) was taken at least one plate thickness from the quenched ends of the plate. All test specimens were machined from the 1/44 thickness locations of the plate after performing a simulated post-weld stress-relieving treatment on the test material. Specimens from weld metal and heat-affected-zone metal were machined from a stress-relieved weldment joining intermediate shell plate B7212-1 and intermediate shell plate B7203-1. All heat-affected-zone specimens were obtained from the weld heat-affected-zone of intermediate shell plate B7212-1.
Charpy V-notch impact specimens from intermediate shell plate B7212-1 were machined both in the longitudinal orientation (longitudinal axis of the specimen parallel to the major rolling direction) and transverse orientation (longitudinal axis of the specimen perpendicular to the major rolling direction).
The core region weld Charpy impact specimens were machined from the weldment such that the long dimension of each Charpy specimen was perpendicular to the weld direction. The notch of the weld metal Charpy specimens was machined such that the direction of crack propagation in the specimen was in the welding direction.
Tensile specimens from intermediate shell plate B7212-1 were machined in both the longitudinal and transverse orientation. Tensile specimens from the weld metal were oriented with the long dimension of the specimen perpendicular to the weld direction.
Bend bar specimens from plate B7212-1 were machined with the longitudinal axis of specimens oriented normal to the rolling direction of the plate such that the simulated crack would propagate in the rolling direction of the plate. All specimens were fatigue pre-cracked according to ASTM E3991' 1.
Compact tension test specimens from plate B7212-1 were machined in both the longitudinal and transverse orientations. Compact tension test specimens from the weld metal were machined perpendicular to the weld direction with the notch oriented in the direction of the weld. All specimens were fatigue pre-cracked according to ASTM E3991' 1.
The chemical composition measurements and heat treatment of the surveillance material is presented in Tables 4-1 through 4-2. The chemical analysis reported in Table 4-1 was obtained from unirradiated material used in the surveillance program[4] and from irradiated capsule W specimens[ 91.

4-2 Capsule V contained dosimeter wires of pure copper, iron, nickel, and aluminum-0.15 weight percent cobalt (cadmium-shielded and unshielded). In addition, cadmium-shielded dosimeters of neptunium (Np237) and uranium (U 238) were placed in the capsule to measure the integrated flux at specific neutron energy levels.
The capsule contained thermal monitors made from two low-melting-point eutectic alloys and sealed in Pyrex tubes. These thermal monitors were used to define the maximum temperature attained by the test specimens during irradiation. The composition of the two eutectic alloys and their melting points are as follows:
2.5% Ag, 97.5% Pb                        Melting Point: 579&deg;F (304'C) 1.75% Ag, 0.75% Sn, 97.5% Pb             Melting.Point: 590&deg;F (310&deg;C)
The arrangement of the various mechanical specimens, dosimeters, and thermal monitors contained in Capsule V is shown in Figure 4-2.

5-1 5         TESTING OF SPECIMENS FROM CAPSULE V 5.1       OVERVIEW The post-irradiation mechanical testing of the Charpy V-notch impact specimens and tensile specimens was performed in the remote metallographic facility (RMF) at the Westinghouse Science and Technology Center.
Upon receipt of the capsule at the laboratory, the capsule was opened per Procedure RMF 8804[003. The specimens and spacer blocks were carefully removed, inspected for identification number and checked against the master list in WCAP-8956, Revision 041. All items were in their proper locations.
Examination of the thermal monitors indicated that the 97.5% Pb, 2.5% Ag monitor melted, while the other did not. Based on this examination, the maximum temperature to which the specimens were exposed was greater than 579&deg;F (304'C) and less than 590'F (310&deg;C).
The testing of the Charpy V-notch and tensile specimens was performed in accordance with ASTM Specification E 185-821"] and Westinghouse Procedures RMF 8402[121 as detailed by Westinghouse Procedures RMF 8102[131 and RMF 8103[141.
The Charpy impact tests were performed per ASTM Specification E23-06 [1 51and Procedure RMF 8103[ 41 on a Tinius-Olsen Model 74, 358J machine. The tup (striker) of the Charpy machine is instrumented with an Instron Impulse instrumentation system, feeding information into a computer. With this system, load-time and energy-time signals can be recorded in addition to the standard measurement of Charpy energy (ED). From the load-time curve, the load of general yielding (PGY), the time to general yielding (Toy), the maximum load (PM), and the time to maximum load (TM) can be determined. Under some test conditions, a sharp drop in load indicative of fast fracture was observed. The load at which fast fracture was initiated is identified as the fast fracture load (PF). If the fast load drop terminates well above zero load, the termination load is identified as the arrest load (PA).
The energy at maximum load (EM) was determined by comparing the energy-time record and the load-time record. The energy at maximum load is approximately equivalent to the energy required to initiate a crack in the specimen. Therefore, the propagation energy for the crack (Ep) is the difference between the total energy to fracture (ED) and the energy at maximum load (EM).
The yield stress (ry)   was calculated from the three-point bend formula having the following expression[161:
L
                                             '3Y =PGY              2                                   (Eq. 5-1)

The constant C is dependent on the notch flank angle ((P), notch root radius (p),

5-2 and the type of loading (i.e., pure bending or three-point bending). In three-point bending, for a Charpy specimen in which y = 450 and p = 0.010 in., Equation 5-1 is valid with C = 1.21.
Therefore, (for L = 4W),
GY =PGY            L        - 3.305P   YW2                          (Eq. 5-2)

For the Charpy specimen, B = 0.394 in., W = 0.394 in., and a = 0.079 in. Equation 5-2 then reduces to:
7y = 33.3 PGy                                        (Eq. 5-3) where uy is in units of psi and PGY is in units of lb. The flow stress was calculated from the average of the yield and maximum loads, also using the three-point bend formula.
Symbol A in columns 4, 5, and 6 of Tables 5-5 through 5-8 is the cross-section area under the notch of the Charpy specimens:
A = B(W-a) = 0.1241 sq. in.                                   (Eq. 5-4)
Percent shear was determined from post-fracture photographs using the ratio-of-areas methods in compliance with ASTM E23-060l"' and A370-071"]I. The lateral expansion was measured using a dial gage rig similar to that shown in the same specifications.
Tensile tests were performed on a 20,000 pound Instron, split console test machine (Model 1115) per ASTM Specification E8-04[18 ] and E21-05[191 and Procedure RMF 81021"]1. Extension measurements were made with a linear variable displacement transducer (LVDT) extensometer. The extensometer gage length was 1.00 inch. Elevated test temperatures were obtained with a three-zone electric resistance split-tube furnace with a nine-inch hot zone. All tests were conducted in air.
The yield load, ultimate load, fracture load, total elongation, and uniform elongation were determined.
directly from the load-extension curve. The yield strength, ultimate strength and fracture strength were calculated using the original cross-sectional area. The final diameter was determined from post-fracture photographs. The fracture area used to calculate the fracture stress (true stress at fracture) and percent reduction in area were computed using the final diameter measurement.
5.2      RESULTS The results of the Charpy V-notch impact tests performed on the various materials contained in Capsule V, which received a fluence of 8.73E+19 n/cm 2 (E> 1.0 MeV) in 21.82 EFPY of operation, are presented in Tables 5-1 through 5-10 and are compared with unirradiated results shown in Figures 5-1 through 5-12.

5-3 The transition temperature increases and USE decreases for the Capsule V materials are summarized in Table 5-9 and led to the following results:
Irradiation of the reactor vessel intermediate shell plate B7212-1 Charpy specimens, oriented with the longitudinal axis of the specimen parallel to the major working direction (longitudinal orientation), resulted in an irradiated 30 ft-lb transition temperature of 196.0'F and an irradiated 50 ft-lb transition temperature of 240.1PF. This results in a 30 ft-lb transition temperature increase of 218.3&deg;F and a 50 ft-lb transition temperature increase of 230.1 F for the longitudinal orientation specimens. See Table 5-9.
Irradiation of the reactor vessel intermediate shell plate B7212-1 Charpy specimens, oriented with the longitudinal axis of the specimen perpendicular to the major working direction (transverse orientation), resulted in an irradiated 30 ft-lb transition temperature of 207.8&deg;F and an irradiated 50 ft-lb transition temperature of 234.3&deg;F. This results in a 30 ft-lb transition temperature increase of 215.3&deg;F and a 50 ft-lb transition temperature increase of 200.7&deg;F for the transverse orientation specimens. See Table 5-9.
Irradiation of the surveillance weld metal Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 22.0&deg;F and an irradiated 50 ft-lb transition temperature of 61.8&deg;F. This results in a 30 ft-lb transition temperature increase of 56.5&deg;F and a 50 ft-lb transition temperature increase of 77.2&deg;F. See Table 5-9.
Irradiation of the weld heat-affected-zone (HAZ) metal Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 26.2&deg;F and an irradiated 50 ft-lb transition temperature of 52.4&deg;F. This results in a 30 ft-lb transition temperature increase of 322.4&deg;F and a 50 ft-lb transition temperature increase of 257.7&deg;F. See Table 5-9.
The average USE of the intermediate shell plate B7212-1 Charpy specimens (longitudinal orientation) resulted in an average energy decrease of 44 ft-lb after irradiation. This results in an irradiated average USE of 86 ft-lb for the longitudinal orientation specimens. See Table 5-9.
The average USE of the intermediate shell plate B7212-1 Charpy specimens (transverse orientation) resulted in an average energy decrease of 26 ft-lb after irradiation. This results in an irradiated average USE of 69 ft-lb for the transverse orientation specimens. See Table 5-9.
The average USE of the surveillance weld metal Charpy specimens resulted in an average energy decrease of 20 ft-lb after irradiation. This results in an irradiated average USE of 124 ft-lb for the weld metal specimens. See Table 5-9.
The average USE of the weld HAZ metal Charpy specimens resulted in an average energy decrease of 40 ft-lb after irradiation. This results in an irradiated average USE of 118 ft-lb for the weld HAZ metal. See Table 5-9.
WCAP-16918-NP                                                                                        April 2008 Revision 1

5-4 A comparison, as presented in Table 5-10, of the Farley Unit 2 reactor vessel surveillance material test results with the Regulatory Guide 1.99, Revision 2[1] predictions led to the following conclusions:
         -       The measured 30 ft-lb shift in transition temperature values of the intermediate shell plate B7212-1 specimens contained in Capsule V (longitudinal and transverse orientations) are less than the Regulatory Guide 1.99, Revision 2, predictions.
         -       The measured 30 ft-lb shift in transition temperature value of the surveillance weld metal contained in Capsule V is less than the Regulatory Guide 1.99, Revision 2EI), prediction.
         -       The measured percent decrease in upper shelf energy (USE) for all the plate and weld surveillance materials in Capsule V are less than the Regulatory 1.99, Revision 21",
predictions.
All beltline materials are expected to have an USE greater than 50 ft-lb through end of license (EOL, 54 EFPY) as required by 10CFR50, Appendix G The service period of applicability for the Pressure-Temperature Limit Curves labeled for 33.8 EFPY in WCAP-14689, Revision 4[3], must be reduced to account for the updated neutron fluence projections and vessel material chemistry factors calculated as part of the Surveillance Capsule V analysis. The new service period for these Pressure-Temperature Limit Curves is 32.8 EFPY.
The fracture appearance of each irradiated Charpy specimen from the various surveillance Capsule V materials is shown in Figures 5-13 through 5-16 and shows an increasingly ductile or tougher appearance with increasing test temperature.
The load-time records for individual instrumented Charpy specimen tests are shown in Appendix B.
Appendix C presents the individual CVGRAPH, Version 5.3, Charpy V-notch plots for each surveillance capsule and the program input data. The credibility evaluation of the Farley Unit 2 surveillance program is presented in Appendix D of this report. The evaluation concluded that the Farley Unit 2 surveillance data is deemed not credible for the weld specimens and credible for the plate specimens.
5.3      TENSILE TEST RESULTS The results of the tensile tests performed on the intermediate shell plate specimens (longitudinal and transverse orientations) and weld metal contained in Capsule V irradiated to 8.73E+19 n/cm2 (E> 1.0 MeV) are presented in Table 5-11 and are compared with unirradiated results[43 as shown in Figures 5-17 through 5-19.
The results of the tensile tests performed on the intermediate shell plate B7212-1 (longitudinal orientation) specimens at 550'F indicated that irradiation to 8.73E+19 n/cm 2 (E> 1.0 MeV) caused approximately a 25 ksi increase in the 0.2 percent offset yield strength and approximately a 19 ksi increase in the ultimate tensile strength when compared to unirradiated dataE4 ]. See Figure 5-17.

See Figure 5-18.
The results of the tensile tests performed on the surveillance weld metal specimens at 550'F indicated that irradiation to 8.73E+19 n/cm 2 (E> 1.0 MeV) caused approximately a 12 ksi increase in the 0.2 percent offset yield strength and approximately a 7 ksi increase in the ultimate tensile strength when compared to unirradiated data[4 ]. See Figure 5-19.
The fractured tensile specimens for the surveillance plate material are shown in Figures 5-20 and 5-21, while the fractured tensile specimens for the surveillance weld metal are shown in Figure 5-22. The engineering stress-strain curves for the tensile tests are shown in Figures 5-23 through 5-25.

6-1 6        RADIATION ANALYSIS AND NEUTRON DOSIMETRY

==6.1      INTRODUCTION==

This section describes a discrete ordinates Sn, transport analysis performed for the Farley Unit 2 reactor to determine the neutron radiation environment within the reactor pressure vessel and surveillance capsules.
In this analysis, fast neutron exposure parameters in terms of fast neutron fluence (E > 1.0 MeV) and iron atom displacements (dpa) were established on a plant and fuel cycle specific basis. An evaluation of the most recent dosimetry sensor set from Capsule V, withdrawn at the end of the eighteenth plant operating cycle, is provided. In addition, to provide an up-to-date data base applicable to the Farley Unit 2 reactor, sensor sets from previously withdrawn capsules (U, W, X, Z, and Y) are presented in Appendix A of this report. Comparisons of the results from these dosimetry evaluations with the analytical predictions served to validate the plant specific neutron transport calculations. These validated calculations subsequently formed the basis for providing projections of the neutron exposure of the reactor pressure vessel for operating periods extending to 60 effective full power years (EFPY).
The use of fast neutron fluence (E > 1.0 MeV) to correlate measured material property changes to the neutron exposure of the material has traditionally been accepted for the development of damage trend curves as well as for the implementation of trend curve data to assess the condition of the vessel. In recent years, however, it has been suggested that an exposure model that accounts for differences in neutron energy spectra between surveillance capsule locations and positions within the vessel wall could lead to an improvement in the uncertainties associated with damage trend curves and improved accuracy in the evaluation of damage gradients through the reactor vessel wall.
Because of this potential shift away from a threshold fluence toward an energy dependent damage function for data correlation, ASTM Standard Practice E853, "Analysis and Interpretation of Light-Water Reactor Surveillance Results,"[20 1recommends reporting displacements per iron atom (dpa) along with fluence (E > 1.0 MeV) to provide a database for future reference. The energy dependent dpa function to be used for this evaluation is specified in ASTM Standard Practice E693, "Characterizing Neutron Exposures in Iron and Low Alloy Steels in Terms of Displacements per Atom." 2 11 The application of the dpa parameter to the assessment of embrittlement gradients through the thickness of the reactor vessel wall has already been promulgated in Revision 2 to Regulatory Guide 1.99, "Radiation Embrittlement of 1
Reactor Vessel Materials."''
All of the calculations and dosimetry evaluations described in this section and in Appendix A were based on the latest available nuclear cross-section data derived from ENDF/B-VI and made use of the latest available calculational tools. Furthermore, the neutron transport and dosimetry evaluation methodologies follow the guidance and meet the requirements of Regulatory Guide 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence"'' 22 . Additionally, the methods used to develop the calculated pressure vessel fluence are consistent with the NRC approved methodology described in WCAP-14040-NP-A, Revision 4 "Methodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves," May 2004[23].
WCAP-16918-NP                                                                                       April 2008 Revision 1

6-2 6.2      DISCRETE ORDINATES ANALYSIS A plan view of the Farley Unit 2 reactor geometry at the core midplane is shown in Figure 6-1. Six irradiation capsules attached to the neutron pad are included in the reactor design that constitutes the reactor vessel surveillance program. The capsules are located at azimuthal angles of 107', 2870, 3430 (17' from the core cardinal axes) and 1100, 2900, 3400 (200 from the core cardinal axes). The stainless steel specimen containers are 1.182-inch by 1-inch and are approximately 56 inches in height. The containers are positioned axially such that the test specimens are centered on the core midplane, thus spanning the central 5 feet of the 12-foot high reactor core.
From a neutronic standpoint, the surveillance capsules and associated support structures are significant.
The presence of these materials has a marked effect on both the spatial distribution of neutron flux and the neutron energy spectrum in the water annulus between the neutron pads and the reactor vessel. In order to determine the neutron environment at the test specimen location, the capsules themselves must be included in the analytical model.
In performing the fast neutron exposure evaluations for the Farley Unit 2 reactor vessel and surveillance capsules, a series of fuel cycle specific forward transport calculations were carried out using the following three-dimensional flux synthesis technique:
0(r, 0, z) = 4)(r, 0)
* 4(r,
                                                                    &#xa2;(r)z) where 0(r,0,z) is the synthesized three-dimensional neutron flux distribution, 0(rO) is the transport solution in r,0 geometry, 0(r,z) is the two-dimensional solution for a cylindrical reactor model using the actual axial core power distribution, and 0(r) is the one-dimensional solution for a cylindrical reactor model using the same source per unit height as that used in the r,0 two-dimensional calculation. This synthesis procedure was carried out for each operating cycle'at Farley Unit 2.
For the Farley Unit 2 transport calculations, two octant-symmetric rO models were developed and are depicted in Figure 6-1. The first model contained the extended neutron pad (26' span) including the surveillance capsules, while the second contained the shortened neutron pad (150 span) with no surveillance capsules. The former model was used to perform surveillance capsule dosimetry evaluations and subsequent comparisons with calculated results, while the latter model was used to generate the maximum fluence at the pressure vessel wall. In developing these analytical models, nominal design dimensions were employed for the various structural components. Likewise, water temperatures, and hence, coolant densities in the reactor core and downcomer regions of the reactor were taken to be representative of full power operating conditions. The coolant densities were treated on a fuel cycle specific basis. The reactor core itself was treated as a homogeneous mixture of fuel, cladding, water, and miscellaneous core structures such as fuel assembly grids, guide tubes, et cetera. The geometric mesh description of the rO reactor models consisted of 185 radial by 92 azimuthal intervals. Mesh sizes were chosen to assure that proper convergence of the inner iterations was achieved on a point-wise basis. The point-wise inner iteration flux convergence criterion utilized in the r,O calculations was set at a value of 0.001.
WCAP- 16918-NP                                                                                       April 2008 Revision 1

6-3 The r,z model used for the Farley Unit 2 calculations is shown in Figure 6-2 and extends radially from the centerline of the reactor core out to a location interior to the primary biological shield and over an axial span from an elevation 1-foot below the active fuel to approximately one-foot above the active fuel. As in the case of the r,0 models, nominal design dimensions and full power coolant densities were employed in the calculations. In this case, the homogenous core region was treated as an equivalent cylinder with a volume equal to that of the active core zone. The stainless steel former plates located between the core baffle and core barrel regions were also explicitly included in the model. The rz geometric mesh description of these reactor models consisted of 149 radial by 178 axial intervals. As in the case of the r,0 calculations, mesh sizes were chosen to assure that proper convergence of the inner iterations was achieved on a point-wise basis. The point-wise inner iteration flux convergence criterion utilized in the r,z calculations was also set at a value of 0.001.
The one-dimensional radial models used in the synthesis procedure consisted of the same 149 radial mesh intervals included in the r,z models. Thus, radial synthesis factors could be determined on a mesh-wise basis throughout the entire geometry.
The core power distributions used in the plant specific transport analysis were taken from the appropriate Farley Unit 2 fuel cycle design reports. The data extracted from the design reports represented cycle-dependent fuel assembly enrichments, bum-ups, and axial power distributions. This information was used to develop spatial and energy dependent core source distributions averaged over each individual fuel cycle. Therefore, the results from the neutron transport calculations provided data in terms of fuel cycle averaged neutron flux, which when multiplied by the appropriate fuel cycle length, generated the incremental fast neutron exposure for each fuel cycle. In constructing these core source distributions, the energy distribution of the source was based on an appropriate fission split for uranium and plutonium isotopes based on the initial enrichment and bum-up history of individual fuel assemblies. From these assembly-dependent fission splits, composite values of energy release per fission, neutron yield per fission, and fission spectrum were determined.
The transport calculations supporting this analysis were carried out using the DORT discrete ordinates code Version 3.2[24] and the BUGLE-96 cross-section library.[25 3 The BUGLE-96 library provides a 67 group coupled neutron-gamma ray cross-section data set produced specifically for light water reactor (LWR) applications. In these analyses, anisotropic scattering was treated with a P 5 legendre expansion and angular discretization was modeled with an S1 6 order of angular quadrature. Energy and space dependent core power distributions, as well as system operating temperatures, were treated on a fuel cycle specific basis.
Selected results from the neutron transport analyses are provided in Tables 6-1 through 6-7. In Table 6-1, the calculated exposure rates and integrated exposures, expressed in terms of both neutron fluence (E > 1.0 MeV) and dpa, are given at the radial and azimuthal center of the two azimuthally symmetric surveillance capsule positions (170 and 200). These results, representative of the axial midplane of the active core, establish the calculated exposure of the surveillance capsules withdrawn to date as well as projected into the future. Similar information is provided in Tables 6-2 and 6-3 for the reactor vessel inner radius. The vessel data given in Table 6-2 are representative of the axial location of the maximum neutron exposure at each of the four azimuthal locations, while Table 6-3 provides neutron exposure data for the intermediate shell course to nozzle shell course weld. It is also important to note that the data for WCAP- 16918-NP                                                                                       April 2008 Revision 1

6-4 the vessel inner radius were taken at the clad/base metal interface, and thus, represent the maximum calculated exposure levels of the vessel plates and welds.
Both calculated fluence (E > 1.0 MeV) and dpa data are provided in Table 6-1 through Table 6-3. These data tabulations include both plant and fuel cycle specific calculated neutron exposures at the end of the 18th operating fuel cycle as well as future projections to 25, 32, 40, 48, 54, and 60 EFPY The projections were based on the assumption that the core power distributions and associated plant operating characteristics from Cycle 19 were representative of future plant operation. The future projections are also based on the current reactor power level of 2775 MWt.
Radial gradient information applicable to fast (E > 1.0 MeV) neutron fluence and dpa are given in Tables 6-4 and 6-5, respectively. The data, based on the cumulative integrated exposures from Cycles 1 through 19, are presented on a relative basis for each exposure parameter at several azimuthal locations.
Exposure distributions through the vessel wall may be obtained by multiplying the calculated exposure at the vessel inner radius by the gradient data listed in Tables 6-4 and 6-5.
The calculated fast neutron exposures for the six surveillance capsules withdrawn from the Farley Unit 2 reactor are provided in Table 6-6. These assigned neutron exposure levels are based on the plant and fuel cycle specific neutron transport calculations performed for the Farley Unit 2 reactor.
Updated lead factors for the Farley Unit 2 surveillance capsules are provided in Table 6-7. The capsule lead factor is defined as the ratio of the calculated fluence (E > 1.0 MeV) at the geometric center of the surveillance capsule to the corresponding maximum calculated fluence at the pressure vessel clad/base metal interface. In Table 6-7, the lead factors for capsules that have been withdrawn from the reactor (U, W, X, Z, Y, and V) were based on the calculated fluence values for the irradiation period corresponding to the time of withdrawal for the individual capsules.
6.3      NEUTRON DOSIMETRY The validity of the calculated neutron exposures previously reported in Section 6.2 is demonstrated by a direct comparison against the measured sensor reaction rates and via a least squares evaluation performed for each of the capsule dosimetry sets. However, since the neutron dosimetry measurement data merely serves to validate the calculated results, only the direct comparison of measured-to-calculated results for the most recent surveillance capsule removed from service is provided in this section of the report. For completeness, the assessment of all measured dosimetry removed to date, based on both direct and least squares evaluation comparisons, is documented in Appendix A.
The direct comparison of measured versus calculated fast neutron threshold reaction rates for the sensors from Capsule V, withdrawn from Farley Unit 2 at the end of the 18th fuel cycle, is summarized below.

This direct comparison falls well within the
 +/- 20% criterion specified in Regulatory Guide 1.190[22]; furthermore, it is consistent with the full set of comparisons given in Appendix A for all measured dosimetry removed to date from the Farley Unit 2 reactor. These comparisons validate the current analytical results described in Section 6.2; therefore, the
,calculations are deemed applicable for Farley Unit 2.
6.4       CALCULATIONAL UNCERTAINTIES The uncertainty associated with the calculated neutron exposure of the Farley Unit 2 surveillance capsule and reactor pressure vessel is based on the recommended approach provided in Regulatory Guide 1.190.[221 In particular, the qualification of the methodology was carried out in the following four stages:
: 1.        Comparison of calculations with benchmark measurements from the pool critical assembly (PCA) simulator at the Oak Ridge National Laboratory (ORNL).
: 2.        Comparisons of calculations with surveillance capsule and reactor cavity measurements from the H. B. Robinson power reactor benchmark experiment.
: 3.       An analytical sensitivity study addressing the uncertainty components resulting from important input parameters applicable to the plant specific transport calculations used in the neutron exposure assessments.
: 4.        Comparisons of the plant specific calculations with all available dosimetry results from the Farley Unit 2 surveillance program.
The first phase of the methods qualification (PCA comparisons) addressed the adequacy of basic transport calculation and dosimetry evaluation techniques and associated cross-sections. This phase, however, did not test the accuracy of commercial core neutron source calculations nor did it address uncertainties in operational or geometric variables that impact power reactor calculations. The second phase of the qualification (H. B. Robinson comparisons) addressed uncertainties in these additional areas that are WCAP-16918-NP                                                                                         April 2008 Revision I

6-6 primarily methods related and would tend to apply generically to all fast neutron exposure evaluations.
The third phase of the qualification (analytical sensitivity study) identified the potential uncertainties introduced into the overall evaluation due to calculational methods approximations as well as to a lack of knowledge relative to various plant specific input parameters. The overall calculational uncertainty applicable to the Farley Unit 2 analysis was established from results of these three phases of the methods qualification.
The fourth phase of the uncertainty assessment (comparisons with Farley Unit 2 measurements) was used solely to demonstrate the validity of the transport calculations and to confirm the uncertainty estimates associated with the analytical results. The comparison was used only as a check and was not used in any way to modify the calculated surveillance capsule and pressure vessel neutron exposures previously described in Section 6.2. As such, the validation of the Farley Unit 2 analytical model based on the measured plant dosimetry is completely described in Appendix A.
The following summarizes the uncertainties developed from the first three phases of the methodology qualification. Additional information pertinent to these evaluations is provided in Reference 22.

The net calculational uncertainty was determined by combining the individual components in quadrature.
Therefore, the resultant uncertainty was random and no systematic bias was applied to the analytical results.
The plant specific measurement comparisons described in Appendix A support these uncertainty assessments for Farley Unit 2.

A-I APPENDIX A VALIDATION OF THE RADIATION TRANSPORT MODELS BASED ON NEUTRON DOSIMETRY MEASUREMENTS A.1      NEUTRON DOSIMETRY Comparisons of measured dosimetry results to both the calculated and least squares adjusted values for all surveillance capsules withdrawn from service to date at Farley Unit 2 are described herein. The sensor sets from these capsules have been analyzed in accordance with the current dosimetry evaluation methodology described in Regulatory Guide 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence" [A-I] One of the main purposes for presenting this material is to demonstrate that the overall measurements agree with the calculated and least squares adjusted values to within +/- 20% as specified by Regulatory Guide 1.190, thus serving to validate the calculated neutron exposures previously reported in Section 6.2 of this report. This information may also be useful in the future, in particular, as least squares adjustment techniques become accepted in the regulatory environment.
A.1.1    Sensor Reaction Rate Determinations In this section, the results of the evaluations of the six neutron sensor sets withdrawn to date as part of the Farley Unit 2 Reactor Vessel Materials Surveillance Program[A-2] are presented. The capsule designation, location within the reactor, and time of withdrawal of each of these dosimetry sets were as follows:

: 1. The cobalt-aluminum measurements include both bare and cadmium-covered sensors.
Since all the dosimetry monitors were accommodated within the dosimeter block centered at the radial, azimuthal, and axial center of the material test specimen array, gradient corrections were not required for these reaction rates. Pertinent physical and nuclear characteristics of the passive neutron sensors are listed in Table A- 1.
The use of passive monitors such as those listed above do not yield a direct measure of the energy dependent neutron flux at the point of interest. Rather, the activation or fission process is a measure of the integrated effect that the time and energy dependent neutron flux has on the target material over the course of the irradiation period. An accurate assessment of the .average neutron flux level incident on the various monitors may be derived from the activation measurements only if the irradiation parameters are well known. In particular, the following variables are of interest:
* The measured specific activity of each monitor 0        The physical characteristics of each monitor
* The operating history of the reactor
* The energy response of each monitor 0        The neutron energy spectrum at the monitor location Results from the radiometric counting of the neutron sensors from Capsules U, W, X, Z, Y, and V are documented in References A-3 through A-7. The radiometric counting of the sensors from Capsule Y and V was carried out by Pace Analytical Services, Inc., located at the Westinghouse Waltz Mill Site. In all cases, the radiometric counting followed established ASTM procedures. Following sample preparation and weighing, the specific activity of each sensor was determined by means of a high-resolution gamma spectrometer. For the copper, iron, nickel, and cobalt-aluminum sensors, analyses were performed by direct counting of each of the individual samples. In the case of the uranium and neptunium fission sensors, the analyses were carried out by direct counting preceded by dissolution and chemical separation of cesium from the sensor material.
WCAP- 16918-NP                                                                                      April 2008 Revision 1

A-3 The irradiation history of the reactor over the irradiation periods experienced by Capsules U, W, X, Z, Y, and V was based on the reported monthly power generation of Farley Unit 2 for Cycles 1 through 18. For the sensor sets utilized in the surveillance capsules, the half-lives of the product isotopes are long enough that a monthly histogram describing reactor operation has proven to be an adequate representation for use in radioactive decay corrections for the reactions of interest in the exposure evaluations. The irradiation history applicable to Capsules U, W, X, Z, Y, and V is given in Table A-2.
Having the measured specific activities, the physical characteristics of the sensors, and the operating history of the reactor, reaction rates referenced to full-power operation were determined from the following equation:
A R=
NoFYZ-, j Cj[1-e-ItIj][e-I'td]
Pref where:
R      =   Reaction rate averaged over the irradiation period and referenced to operation at a core power level of Pref (rps/nucleus)
A      =   Measured specific activity (dps/gm)
No     =   Number of target element atoms per gram of sensor F      =   Atom fraction of the target isotope in the target element Y      =   Number of product atoms produced per reaction Pj     =   Average core power level during irradiation period j (MWt)
Pref   =   Maximum or reference power level of the reactor (MWt)
Cj     =   Calculated ratio of O(E > 1.0 MeV) during irradiation period j to the time weighted average O(E > 1.0 MeV) over the entire irradiation period.
                =   Decay constant of the product isotope (1/sec) tj     =   Length of irradiation period j (sec) td     =   Decay time following irradiation period j (sec) and the summation is carried out over the total number of monthly intervals comprising the irradiation period.
WCAP- 16918-NP                                                                                       April 2008 Revision 1

A-4 In the equation describing the reaction rate calculation, the ratio [Pj]/[Pref] accounts for month-by-month variation of reactor core power level within any given fuel cycle as well as over multiple fuel cycles. The ratio Cj, which was calculated for each fuel cycle using the transport methodology discussed in Section 6.2, accounts for the change in sensor reaction rates caused by variations in flux level induced by changes in core spatial power distributions from fuel cycle to fuel cycle. For a single-cycle irradiation, Cj is normally taken to be 1.0. However, for multiple-cycle irradiations, particularly those employing low leakage fuel management, the additional Cj term should be employed. The impact of changing flux levels for constant power operation can be quite significant for sensor sets that have been irradiated for many cycles in a reactor that has transitioned from non-low leakage to low leakage fuel management or for sensor sets contained in surveillance capsules that have been moved from one capsule location to another.
The fuel cycle specific neutron flux values along with the computed values for Cj are listed in Table A-3.
These flux values represent the cycle dependent results at the radial and azimuthal center of the respective capsules at the axial elevation of the active fuel midplane.
Prior to using the measured reaction rates in the least-squares evaluations of the dosimetry sensor sets, additional corrections were made to the 238U and 237Np measurements to account for the presence of 235U impurities in the sensors as well as to adjust for the build-in of plutonium isotopes over the course of the 238 irradiation. Corrections were also made to the       U sensor reaction rates to account for gamma ray induced fission reactions that occurred over the course of the capsule irradiations. The correction factors applied to the Farley Unit 2 fission sensor reaction rates for Capsule V are summarized as follows:
Capsule Correction                 U            W             X              Z           Y           V 235 U  Impurity/Pu Build-in         0.861        0.818         0.777          0.714       0.663       0.618 238 Photo-fission,     U(y,f)          0.976        0.978         0.976          0.978       0.978       0.976 Net  238U Correction               0.840        0.800         0.758          0.698       0.648       0.603 Photo-fission, 237 Np(y,f)         0.994        0.994         0.994          0.994       0.994       0.994 These factors were applied in a multiplicative fashion to the decay-corrected uranium fission sensor reaction rates.
Results of the sensor reaction rate determinations for Capsules U, W, X, Z, Y, and V are given in Tables A-4a through A-4f, respectively. The measured specific activities, decay corrected saturated specific activities, and computed reaction rates for each sensor indexed to the radial center of the capsule are listed in these tables. The fission sensor reaction rates are listed both with and without the applied corrections for 238U impurities, plutonium build-in, and gamma ray induced fission effects.
A.1.2     Least Squares Evaluation of Sensor Sets Least squares adjustment methods provide the capability of combining the measurement data with the corresponding neutron transport calculations resulting in a Best Estimate neutron energy spectrum with associated uncertainties. Best Estimates for key exposure parameters such as O(E > 1.0 MeV) or dpals along with their uncertainties are then easily obtained from the adjusted spectrum. In general, the least squares methods, as applied to surveillance capsule dosimetry evaluations, act to reconcile the measured sensor WCAP-16918-NP                                                                                        April 2008 Revision 1

A-5 reaction rate data, dosimetry reaction cross-sections, and the calculated neutron energy spectrum within their respective uncertainties. For example, Ri +/-    Ri =     (Gig +/- 8g)O@i g +/-  0g) g relates a set of measured reaction rates, Ri, to a single neutron spectrum, Og, through the multigroup dosimeter reaction cross-section, Gig, each with an uncertainty 6. The primary objective of the least squares evaluation is to produce unbiased estimates of the neutron exposure parameters at the location of the measurement.
For the least squares evaluation of the Farley Unit 2 surveillance capsule dosimetry, the FERRET code[A-S8 was employed to combine the results of the plant specific neutron transport calculations and sensor set reaction rate measurements to determine best-estimate values of exposure parameters (O(E > 1.0 MeV) and dpa) along with associated uncertainties for the six in-vessel capsules withdrawn to date.
The application of the least squares methodology requires the following input:
: 1.      The calculated neutron energy spectrum and associated uncertainties at the measurement location
: 2.       The measured reaction rates and associated uncertainty for each sensor contained in the multiple foil set
: 3.       The energy dependent dosimetry reaction cross-sections and associated uncertainties for each sensor contained in the multiple foil sensor set For the Farley Unit 2 application, the calculated neutron spectrum was obtained from the results of plant specific neutron transport calculations described in Section 6.2 of this report. The sensor reaction rates were derived from the measured specific activities using the procedures described in Section A. 1.1. The dosimetry reaction cross-sections and uncertainties were obtained from the SNLRML dosimetry cross-section library [A-9]. The SNLRML library is an evaluated dosimetry reaction cross-section compilation recommended for use in LWR evaluations by ASTM Standard El018, "Application of ASTM Evaluated Cross-Section Data File, Matrix E 706 (1IB)."
The uncertainties associated with the measured reaction rates, dosimetry cross-sections, and calculated neutron spectra were input to the least squares procedure in the form of variances and covariances. The assignment of the input uncertainties followed the guidance provided in ASTM Standard E 944, "Application of Neutron Spectrum Adjustment Methods in Reactor Surveillance."
The following provides a summary of the uncertainties associated with the least squares evaluation of the Farley Unit 2 surveillance capsule sensor sets.
Reaction Rate Uncertainties The overall uncertainty associated with the measured reaction rates includes components due to the basic measurement process, irradiation history corrections, and corrections for competing reactions. A high WCAP- 16918-NP                                                                                       April 2008 Revision 1

A-6 level of accuracy in the reaction rate determinations is assured by utilizing laboratory procedures that conform to the ASTM National Consensus Standards for reaction rate determinations for each sensor type.
After combining all of these uncertainty components, the sensor reaction rates derived from the counting and data evaluation procedures were assigned the following net uncertainties for input to the least squares evaluation:
These uncertainties are given at the 1 level.
Dosimetry Cross-Section Uncertainties The reaction rate cross-sections used in the least squares evaluations were taken from the SNLRML library. This data library provides reaction cross-sections and associated uncertainties, including covariances, for 66 dosimetry sensors in common use. Both cross-sections and uncertainties are provided in a fine multi-group structure for use in least squares adjustment applications. These cross-sections were compiled from the most recent cross-section evaluations and they have been tested with respect to their accuracy and consistency for least squares evaluations. Further, the library has been empirically tested for use in fission spectra determination as well as in the fluence and energy characterization of 14 MeV neutron sources.
For sensors included in the Farley Unit 2 surveillance program, the following uncertainties in the fission spectrum averaged cross-sections are provided in the SNLRML documentation package.
WCAP- 16918-NP                                                                                     April 2008 Revision 1

A-7 These tabulated ranges provide an indication of the dosimetry cross-section uncertainties associated with the sensor sets used in Light Water Reactor (LWR) irradiations.
Calculated Neutron Spectrum The neutron spectra input to the least squares adjustment procedure were obtained directly from the results of plant specific transport calculations for each surveillance capsule irradiation period and location. The spectrum for each capsule was input in an absolute sense (rather than as simply a relative spectral shape). Therefore, within the constraints of the assigned uncertainties, the calculated data were treated equally with the measurements.
While the uncertainties associated with the reaction rates were obtained from the measurement procedures and counting benchmarks and the dosimetry cross-section uncertainties were supplied directly with the SNLRML library, the uncertainty matrix for the calculated spectrum was constructed from the following relationship:
2 Mgg, =R        +Rg *Rg, *Pgg, where Rn specifies an overall fractional normalization uncertainty and the fractional uncertainties Rg and Rg, specify additional random group-wise uncertainties that are correlated with a correlation matrix given by:
Pgg, = [lP - 0gg, + 0 e-H where:
H-= (g -g),)
2y 2 The first term in the correlation matrix equation specifies purely random uncertainties, while the second term describes the short-range correlations over a group range y (0 specifies the strength of the latter term). The value of 8 is 1.0 when g = g', and is 0.0 otherwise.
The set of parameters defining the input covariance matrix for the Farley Unit 2 calculated spectra was as follows:
Flux Normalization Uncertainty (Rn)                           15%

In Table A-5, measured, calculated, and best-estimate values for sensor reaction rates are given for each capsule. Also provided in this tabulation are ratios of the measured reaction rates to both the calculated and least squares adjusted reaction rates.
These ratios of M/C and M/BE illustrate the consistency of the fit of the calculated neutron energy spectra to the measured reaction rates both before and after adjustment. In Table A-6, comparison of the calculated and best estimate values of neutron flux (E > 1.0 MeV) and iron atom displacement rate are tabulated along with the BE/C ratios observed for each of the capsules.
A distinction should be made between the Best Estimate/Calculation, or [BE]/[C], ratios and the Measurement/Calculation, or [M]/[C], ratios. In this case, Best Estimate values refer to the combination of calculation and measurement via a least squares adjustment procedure to arrive at the best estimate of the neutron flux (E > 1.0 MeV) with an associated uncertainty. The least squares procedure provides a weighting of calculated and measured input based on the energy response and uncertainty associated with each input parameter. The [BE]/[C] ratios, therefore, represent a comparison of the results of the least squares adjustment with the analytical prediction of the neutron flux (E > 1.0 MeV). The [M]/[C] ratios, on the other hand, provide a direct comparison of actual calculated and measured individual foil reaction rates. Using the [M]/[C] data, a direct comparison of calculated and measured neutron flux (E > 1.0 MeV) can not be made without a suitable weighting of the individual foil results.
The data comparisons provided in Tables A-5 and A-6 show that the adjustments to the calculated spectra are relatively small and well within the assigned uncertainties for the calculated spectra, measured sensor reaction rates, and dosimetry reaction cross-sections. Further, these results indicate that the use of the least squares evaluation results in a reduction in the uncertainties associated with the exposure of the surveillance capsules. From Section 6.4 of this report, it may be noted that the uncertainty associated with the unadjusted calculation of neutron fluence (E > 1.0 MeV) and iron atom displacements at the surveillance capsule locations is specified as 12 percent at the I1a level. From Table A-6, it is noted that the corresponding uncertainties associated with the least squares adjusted exposure parameters have been reduced to 6 percent to 8 percent for neutron flux (E > 1.0 MeV) and 8 percent to 10 percent for iron atom displacement rate. Again, the uncertainties from the least squares evaluation are at the 1a level.
WCAP-16918-NP                                                                                       April 2008 Revision 1

A-9 Further comparisons of the measurement results with calculations are given in Tables A-7 and A-8. These comparisons are given on two levels. In Table A-7, calculations of individual threshold sensor reaction rates are compared directly with the corresponding measurements. These threshold reaction rate comparisons provide a good evaluation of the accuracy of the fast neutron portion of the calculated energy spectra. In Table A-8, calculations of fast neutron exposure rates in terms of O(E > 1.0 MeV) and dpa/s are compared with the best estimate results obtained from the least squares evaluation of the capsule dosimetry results. These two levels of comparison yield consistent and similar results with all measurement-to-calculation comparisons falling well within the 20 percent limits specified as the acceptance criteria in Regulatory Guide 1.190.
In the case of the direct comparison of measured and calculated sensor reaction rates, the MIC comparisons for fast neutron reactions range from 0.79 to 1.16 for the 27 samples included in the data set.
The overall average M/C ratio for the entire set of Farley Unit 2 data is 0.94 with an associated standard deviation of 9.7 percent.
In the comparisons of best estimate and calculated fast neutron exposure parameters, the corresponding BE/C comparisons for the capsule data sets range from 0.85 to 1.04 for neutron flux (E > 1.0 MeV), and from 0.87 to 1.04 for iron atom displacement rate. The overall average BE/C ratios for neutron flux (E > 1.0 MeV) and iron atom displacement rate are 0.91 with a standard deviation of 7.8 percent and 0.93 with a standard deviation of 6.9 percent, respectively.
Based on these comparisons, it is concluded that the calculated fast neutron exposures provided in Section 6.2 of this report are validated for use in the assessment of the condition of the materials comprising the beltline region of the Farley Unit 2 reactor pressure vessel.

: 2. The average 238U (n,f) reaction rate of 3.51E-14 includes a correction factor of 0.714 to account for plutonium build-in and an additional factor of 0.978 to account for photo-fission effects in the sensor.
: 3. The average 237Np (n,f) reaction rate of 2.56E-13 includes a correction factor of 0.994 to account for photo-fission effects in the sensor.
: 4. The reaction rate for 237Np (n,f) 137Cs (Cd) for Capsule Z was not used in the FERRET least square evaluation due to inconsistency of 237Np (n,f) 137Cs measurement relative to the 3-loop neutron pad data base'.

C-1 APPENDIX C CHARPY V-NOTCH PLOTS FOR EACH CAPSULE USING SYMMETRIC HYPERBOLIC TANGENT CURVE-FITTING METHOD Contained in Table C-I are the USE values used as input for the generation of the Charpy V-notch plots using CVGRAPH, Version 5.3. The definition for USE is given inASTM E185-82[c-'], Section 4.18, and reads as follows:
          "upper shelf energy level - the average energy value for all Charpy specimens (normally three) whose test temperature is above the upper end of the transition region. For specimens tested in sets of three at each test temperature, the set having the highest average may be regarded as defining the upper shelf energy."
If there are specimens tested in sets of three at each temperature, Westinghouse reports the set having the highest average energy as the USE (usually unirradiated material). If the specimens were not tested in sets of three at each temperature, Westinghouse reports the average of all Charpy data (> 95% shear) as the USE. Hence, the USE values reported in Table C-i, which were used to generate the Charpy V-notch curves, were determined utilizing this methodology.
The lower shelf energy values were fixed at 2.2 ft-lb for all cases.

D-1 APPENDIX D JOSEPH M. FARLEY UNIT 2 SURVEILLANCE PROGRAM CREDIBILITY EVALUATION D.1      INTRODUCTION Regulatory Guide 1.99, Revision 2 [Reference D-1] describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of the low-alloy steels currently used for light-water-cooled reactor vessels. Positions 2.1 and 2.2 of Regulatory Guide 1.99, Revision 2, describe the method for calculating the adjusted reference temperature and Charpy USE of reactor vessel beltline materials using surveillance capsule data. The methods of Positions 2.1 and 2.2 can only be applied when two or more credible surveillance data sets become available from the reactor in question.
To date there have been six surveillance capsules removed from the Farley Unit 2 reactor vessel. To use these surveillance data sets without additional margin, they must be shown to be credible. In accordance with the discussion of Regulatory Guide 1.99, Revision 2, there are five requirements that, must be met for the surveillance data to be judged credible.
The purpose of this evaluation is to apply the credibility requirements of Regulatory Guide 1.99, Revision 2, to the Farley Unit 2 reactor vessel surveillance data and determine if that surveillance data is credible.
D.2      EVALUATION Criterion 1 Materials in the capsules should be those judged most likely to be controlling with regard to radiation embrittlement.
The beltline region of the reactor vessel is defined in Appendix G to 10 CFR Part 50, "Fracture Toughness Requirements,'[D-2] as follows:
          "the reactor vessel (shellmaterial including welds, heat affected zones, andplates orforgings) that directly surrounds the effective height of the active core and adjacentregions of the reactor vessel that are predictedto experience sufficient neutron radiationdamage to be consideredin the selection of the most limiting materialwith regardto radiationdamage."
The Farley Unit 2 reactor vessel consists of the following beltline region materials:
* Intermediate Shell Plates B7203-1 and B7212-1
* Lower Shell Plates B7210-1 and B7210-2
* Intermediate to Lower Shell Circumferential Weld Seam 11-923 (Heat #5P5622)
* Intermediate Shell Axial Weld Seams 19-923A (Heat #HODA) and 19-923B (Heat #BOLA) 0        Lower Shell Axial Weld Seams 20-923A and 20-923B (both Heat #83640)
WCAP- 16918-NP                                                                                      April 2008 Revision 1

D-2 The Farley Unit 2 surveillance program utilizes longitudinal and transverse test specimens from intermediate shell plate B7212-1. The surveillance weld metal was fabricated with weld wire heat #
BOLA.
Per Reference D-3, the Farley Unit 2 surveillance program was based on ASTM E 185-73, "Standard Recommended Practice for Surveillance Tests for Nuclear Reactor Vessels" [Ref. D-4]. Per Section 4.1 of ASTM E 185-73, "The base metal and weld metal to be included in the program should represent the material that may limit the operation of the reactor during its lifetime. The test material should be selected on the basis of initial transition temperature, upper shelf energy level and estimated increase in transition temperature considering chemical composition (copper (Cu) and phosphorus (P)) and neutron fluence." At the time when the Farley Unit 2 surveillance program material was developed, intermediate shell plate B7212-1 was judged to be the most limiting and was therefore utilized in the surveillance program.
The Farley Unit 2 surveillance program weld was fabricated using the shielded metal arc welding process and E8018 stick electrodes, in a manner similar to that used to fabricate middle shell axial seams 19-923A (heat HODA) and 19-923B (heat BOLA). These electrodes were not copper-coated and do not exhibit the chemical variability found in copper-coated submerged arc weld wire. Although the surveillance weld material does not represent the limiting reactor vessel beltline weld, the results of mechanical property tests performed on the surveillance weld are considered to be representative of the property changes expected in the reactor vessel beltline seams. The NRC explicitly approved the selection of the Farley Unit 2 surveillance weld material on the basis that the limiting beltline material (i.e., intermediate plate B7212-1) was included in the surveillance program and conservative methods of analysis contained in Regulatory Guide 1.99 were available to predict the radiation characteristics of the limiting beltline weld.
The NRC incorporated an exemption to the requirements of Appendix H to 10CFR50 in the Farley Unit 2 Operating License, thereby approving the selected surveillance weld material based on the NRC evaluation.
Although the Farley Unit 2 surveillance weld material does not meet the requirements of Criterion 1, conservative methods of analysis are available to predict the radiation characteristics of the limiting beltline weld. The limiting beltline material is intermediate plate B7212-1 which is more limiting than any of the reactor vessel beltline welds and is included in the reactor vessel material surveillance program. Therefore, the Farley Unit 2 reactor vessel material surveillance program provides assurance that the radiation damage to the vessel can be adequately determined and the integrity of the Farley Unit 2 reactor vessel will be ensured during normal plant operations and anticipated operational occurrences.
Therefore, the Farley Unit 2 surveillance program meets this criterion.
Criterion 2 Scatter in the plots of Charpy energy versus temperature for the irradiated and unirradiated conditions should be small enough to permit the determination of the 30 ft-lb temperature and USE unambiguously.
WCAP- 16918-NP                                                                                       April 2008 Revision I

D-3 All of the Farley Unit 2 Charpy energy versus temperature surveillance program data can be found in Appendix C, including data for the unirradiated material. Charpy V-Notch test data for the Farley Unit 2 Surveillance Capsule V specimens is tabulated in Tables 5-1 through 5-4, with scatter that falls within the expected variance of test results for these materials. Based on engineering judgment, the scatter in the data presented in these plots is small enough to permit the determination of the 30 ft-lb temperature and the USE of the Farley Unit 2 surveillance materials unambiguously. Hence, the Farley Unit 2 surveillance program meets this criterion.
Criterion 3 When there are two or more sets of surveillance data from one reactor, the scatter of ARTNDT values about a best-fit line drawn as described in Regulatory Position 2.1 normally should be less than 28&deg;F for welds and 17'F for base metal. Even if the fluence range is large (two or more orders of magnitude), the scatter should not exceed twice those values. Even if the data fail this criterion for use in shift calculations, they may be credible for determining decrease in USE if the upper shelf can be clearly determined, following the definition given in ASTM E1 8 5 - 8 2 ID-4.
The functional form of the least squares method as described in Regulatory Position 2.1 is utilized to determine a best-fit line for this data and to determine if the scatter of these ARTNDT values about this line is less than 28&deg;F for welds and less than 177F for the plate.
The Farley Unit 2 plate and weld specimens are both evaluated for credibility. The weld is made from weld wire heat #BOLA; no other plant has this weld wire heat in their surveillance program and, thus, this assessment does not utilize data from other surveillance programs.
Credibility Assessment Since all surveillance data is from one vessel (Farley Unit 2), the measured ARTNDT and fluence factor (FF) should be used to calculate the chemistry factor to determine if the surveillance material test results are credible.
The chemistry factors for the Farley Unit 2 surveillance plate and weld material contained in the surveillance program were calculated per Regulatory Guide 1.99, Revision 2, Position 2.1, including the negative shifts in RTNDT as determined from the curve fit data. These chemistry factor calculations, used to calculate ARTNDT scatter between the measured and predicted values, are provided in Table D- 1. The credibility calculations are presented in Table D-2.
Plate Evaluation Table D-2 indicates that two of the measured ARTNDT values are slightly below the lower bound of lI (171F) by less than 57F. This indicates that the best fit line would slightly over-predict these measured ARTNDT values. Table D-2 also indicates that one of the measured ARTNDT values is slightly above the upper bound of 1lT (17&deg;F) by approximately 37F.

D-6 From a statistical point of view, +/- ly (171F) would be expected to encompass 75 percent of the data. It is still statistically acceptable to have 3 of 12 points fall outside the +/- 1Ii bound. The fact that 3 measured ARTNDT values are slightly outside the bound of 17&deg;F can be attributed to several factors, such as: 1) the inherent uncertainty in the Charpy test data, 2) the use of symmetric hyperbolic tangent Charpy curve fitting program versus an asymmetric hyperbolic tangent Charpy curve fitting program or a hand drawn curve using engineering judgment, and/or 3) rounding errors.
Looking at the data given in Table D-2, eight of the measured ARTNDT values are within 7&deg;F of the predicted values for the plates. Hence, based on the arguments above, the plate data meets the intent of this criterion. (Note that this approach is consistent with the previous evaluation of the Capsule Y data.)
Weld Evaluation Table D-2 indicates that four of the six surveillance data points are outside the +/- I a of 28&deg;F scatter band for the surveillance weld material; therefore, the surveillance weld data is deemed "not credible" per the third criterion.
Criterion 4 The irradiation temperature of the Charpy specimens in the capsule should match the vessel wall temperature at the cladding/base metal interface within +/- 25&deg;F.
The capsule specimens are located in the reactor between the neutron pad and the vessel wall and are positioned opposite the center of the core. The test capsules are in baskets attached to the neutron pad.
The location of the specimens with respect to the reactor vessel beltline provides assurance that the reactor vessel wall and the specimens experience equivalent operating conditions such that the temperatures will not differ by more than 25&deg;F. Hence, this criterion is met.
Criterion 5 The surveillance data for the correlation monitor material in the capsule should fall within the scatter band of the database for that material.
The Farley Unit 2 surveillance program does not contain correlation monitor material. Therefore, this criterion is not applicable to the Farley Unit 2 surveillance program.
D.3        CONCLUSION Based on the preceding responses to all five criteria of Regulatory Guide 1.99, Revision 2, Section B, the Farley Unit 2 surveillance data is deemed credible for the plate specimens and non-credible for the weld specimens. Credibility of surveillance data is used to determine the appropriate margin term for calculation of adjusted reference temperature in accordance with Reference D-1. Credible plate surveillance data may utilize a reduced oT.term of 8.5&deg;F, while the non-credible weld surveillance data must utilize the full (T.term of 28TF, in calculation of the margin term for determining the respective vessel materials' Position 2.1 adjusted reference temperatures.
