==SUMMARY==
The purpose of this report is to document the testing results of surveillance Capsule Z from Vogtle Unit 2.Capsule Z was removed at 18.48 effective full power years (EFPY) and post-irradiation mechanical tests of the Charpy V-notch and tensile specimens were performed, along with a fluence evaluation.
Capsule Z received a fluence of 4.16 x 1019 n/cm 2 (E > 1.0 MeV) after irradiation to 18.48 EFPY. The peak clad/base metal interface vessel fluence after 18.48 EFPY of plant operation was 1.00 x 1019 n/cm 2 (E >1.0 MeV).This evaluation led to the following conclusions: 
: 1) The measured percent decreases in upper-shelf energy for all the surveillance materials contained in Vogtle Unit 2 Capsule Z are less than the Regulatory Guide 1.99, Revision 2 [Ref. 1] predictions. 
: 2) The Vogtle Unit 2 surveillance plate data is judged to be not credible; however, the weld data is judged to be credible.
This credibility evaluation can be found in Appendix D. 3) All beltline materials exhibit a more than adequate upper-shelf energy level for continued safe plant operation and are predicted to maintain an upper-shelf energy greater than 50 ft-lb through end-of-license (36 EFPY) and end-of-license renewal (57 EFPY) as required by 10 CFR 50, Appendix G [Ref. 2]. The upper-shelf energy evaluation is presented in Appendix E.Lastly, a brief summary of the Charpy V-notch testing can be found in Section 1. All Charpy V-notch data was plotted using a symmetric hyperbolic tangent curve-fitting program.WCAP-17343-NP March 20 1 Revision 0 Westinghouse Non-Proprietary Class 3 1-1 1 

==SUMMARY==
OF RESULTS The analysis of the reactor vessel materials contained in surveillance Capsule Z, the fifth capsule removed and tested from the Vogtle Unit 2 reactor pressure vessel, led to the following conclusions: " Charpy V-notch test data were plotted using a symmetric hyperbolic tangent curve-fitting program.Appendix C presents the CVGRAPH, Version 5.3, Charpy V-notch plots for Capsule Z and previous capsules, along with the program input data.* Capsule Z received an average fast neutron fluence (E > 1.0 MeV) of 4.16 x 1019 n/cm 2 after 18.48 EFPY of plant operation.
* Irradiation of the reactor vessel Lower Shell Plate B8628-1 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 67.8'F and an irradiated 50 ft-lb transition temperature of 106.8 0 F. This results in a 30 ft-lb transition temperature increase of 59.0&deg;F and a 50 ft-lb transition temperature increase of 61.4&deg;F for the longitudinally oriented specimens.
* Irradiation of the reactor vessel Lower Shell Plate B8628-1 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 103.9&deg;F and an irradiated 50 ft-lb transition temperature of 140. I&deg;F. This results in a 30 ft-lb transition temperature increase of 75.3&deg;F and a 50 ft-lb transition temperature increase of 70.0'F for the transversely oriented specimens.
* Irradiation of the Surveillance Program Weld Metal (Heat # 87005) Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 2. I&deg;F and an irradiated 50 ft-lb transition temperature of 48.3&deg;F. This results in a 30 ft-lb transition temperature increase of 21.3&deg;F and a 50 ft-lb transition temperature increase of 37.2'F." Irradiation of the Heat-Affected Zone (HAZ) Material Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of -75.1 F and an irradiated 50 ft-lb transition temperature of-41.2&deg;F.
This results in a 30 ft-lb transition temperature increase of 8.6&deg;F and a 50 ft-lb transition temperature increase of 11.2'F." The average upper-shelf energy of Lower Shell Plate B8628-1 (longitudinal orientation) did not change after irradiation.
This results in an irradiated average upper-shelf energy of 89.0 ft-lb for the longitudinally oriented specimens.
* The average upper-shelf energy of Lower Shell Plate B8628-1 (transverse orientation) resulted in an average energy decrease of 2.0 ft-lb after irradiation.
This results in an irradiated average upper-shelf energy of 68.0 ft-lb for the transversely oriented specimens." The average upper-shelf energy of the Surveillance Program Weld Metal Charpy specimens resulted in an average energy decrease of 2.0 ft-lb after irradiation.
This results in an irradiated average upper-shelf energy of 90.0 ft-lb for the weld metal specimens.
WCAP- 17343-NP March 2011 Revision 0 1-2 Westinghouse Non-Proprietary Class 3* The average upper-shelf energy of the HAZ Material Charpy specimens resulted in an average energy increase of 6.0 ft-lb after irradiation.
This results in an irradiated average upper-shelf energy of 112.0 ft-lb for the HAZ Material.* Comparisons of the measured 30 ft-lb shift in transition temperature values and upper-shelf energy decreases to those predicted by Regulatory Guide 1.99, Revision 2 [Ref. 1] for the Vogtle Unit 2 reactor vessel surveillance materials are presented in Table 5-10.* Based on the credibility evaluation presented in Appendix D, the Vogtle Unit 2 surveillance plate data is not credible but the surveillance weld data is credible." Based on the upper-shelf energy evaluation in Appendix E, all beltline materials exhibit a more than adequate upper-shelf energy level for continued safe plant operation and are predicted to maintain an upper-shelf energy greater than 50 ft-lb through end-of-license (36 EFPY) and end-of-license renewal (57 EFPY) as required by 10 CFR 50, Appendix G [Ref. 2]." The calculated 36 EFPY (end-of-license) and 57 EFPY (end-of-license renewal) neutron fluence (E > 1.0 MeV) at the core mid-plane for the Vogtle Unit 2 reactor vessel using the Regulatory Guide 1.99, Revision 2 attenuation formula (i.e., Equation #3 in the guide) are as follows: Calculated (36 EFPY): Calculated (57 EFPY): Vessel inner radius* = 2.00 x 1019 n/cm 2 (Taken from Table 6-2)Vessel 1/4 thickness 
= 1.192 x 1019 n/cm 2 Vessel inner radius* = 3.19 x 1019 n/cm 2 (Interpolated from Table 6-2)Vessel 1/4 thickness 
= 1.901 x 1019 n/cm 2* Clad/base metal interface.
WCAP- 17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 2-1 2 INTRODUCTION This report presents the results of the examination of Capsule Z, the fifth capsule removed and tested in the continuing surveillance program, which monitors the effects of neutron irradiation on the Southern Nuclear Operating Company Vogtle Unit 2 reactor pressure vessel materials under actual operating conditions.
The surveillance program for the Vogtle Unit 2 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-1 1381[Ref. 3], "Georgia Power Company Alvin W. Vogtle Unit No. 2 Reactor Vessel Radiation Surveillance Program." The surveillance program was planned to cover the 40-year design life of the reactor pressure vessel and was based on ASTM E185-82 [Ref. 4], "Standard Practice for Conducting Surveillance Tests for Light-Water Cooled Nuclear Power Reactor Vessels." Capsule Z was removed from the reactor after 18.48 EFPY of exposure and shipped to the Westinghouse Research and Technology Unit (RTU) Hot Cell Facility, where the post-irradiation mechanical testing of the Charpy V-notch impact and tensile surveillance specimens was performed.
This report summarizes the testing of the post-irradiation data obtained from surveillance Capsule Z removed from the Vogtle Unit 2 reactor vessel and discusses the analysis of the data.WCAP-17343-NP March 2011 Revision 0 

Westinghouse Non-Proprietary Class 3 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 Vogtle 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 Code [Ref. 5]. 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 [Ref. 6]) 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 (K 1 c curve) which appears in Appendix G to Section XI of the ASME Code[Ref. 5]. The KI, 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 K 1 c 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 Vogtle Unit 2 reactor vessel radiation surveillance program, in which a surveillance capsule is periodically removed from the operating nuclear reactor and the encapsulated specimens are 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 (initial RTNDT + M + ARTNDT) is used to index the material to the Kic 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.
WCAP-17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 4-1 4 DESCRIPTION OF PROGRAM Six surveillance capsules for monitoring the effects of neutron exposure on the Vogtle Unit 2 reactor pressure vessel core region (beltline) materials were inserted in the reactor vessel prior to initial plant startup. 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.The capsules contain specimens made from the following:
* Lower Shell Plate B8628-1 (longitudinal orientation)
* Lower Shell Plate B8628-1 (transverse orientation)
* Weld metal fabricated with 3/16-inch Mil B-4 weld filler wire, Heat Number 87005 Linde Type 124 flux, Lot Number 1061, which is identical to that used in the actual fabrication of the intermediate to lower shell circumferential weld seam* Weld heat-affected zone (HAZ) material of Lower Shell Plate B8628-1 Test material obtained from the lower shell plate (after thermal heat treatment and forming of the plate)was taken at least one plate thickness from the quenched edges of the plate. All test specimens were machined from the '/4 and 3/4 thickness locations of the plate after performing a simulated post-weld stress-relieving treatment on the test material.
Test specimens were also removed from weld and heat-affected zone metal of a stress-relieved weldment joining Lower Shell Plate B8628-1 and adjacent Lower Shell Plate B8825-1. All heat-affected zone specimens were obtained from the weld heat-affected zone of Lower Shell Plate B8628-1.Charpy V-notch impact specimens from Lower Shell Plate B8628-1 were machined in the longitudinal orientation (longitudinal axis of the specimen parallel to the major rolling direction) and also in the 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 (normal) 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 Lower Shell Plate B8628-1 were machined in both the longitudinal and transverse orientations.
Tensile specimens from the weld metal were oriented perpendicular to the welding direction.
Compact Test (CT) specimens from Lower Shell Plate B8628-1 were machined in the longitudinal and transverse orientations.
CT specimens from the weld metal were machined with the notch oriented in the direction of welding. All specimens were fatigue pre-cracked according to ASTM E399 [Ref. 7].All six capsules contained dosimeter wires of pure iron, copper, nickel, and aluminum-0.
15 weight percent cobalt (cadmium-shielded and unshielded).
In addition, cadmium-shielded dosimeters of Neptunium (2 3 7 Np) and Uranium (2 3 8 U) were placed in the capsules to measure the integrated flux at specific neutron energy levels.WCAP- 17343-NP March 2011 Revision 0 4-2 Westinghouse Non-Proprietary Class 3 The capsules contained thermal monitors made from two low-melting-point eutectic alloys, which were 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 1.5% Ag, 1.0% Sn, 97.5% Pb Melting Point: 579'F (304'C)Melting Point: 590'F (310 0 C)The chemical composition of the unirradiated surveillance materials is presented in Tables 4-1 and 4-2.Also contained in Tables 4-1 and 4-2 is the chemical composition of the surveillance materials that were irradiated in Capsule Y. The unirradiated data in Tables 4-1 and 4-2 was obtained from the original surveillance program report, WCAP-1 1381 [Ref. 3], Appendix A. The irradiated data in Tables 4-1 and 4-2 was obtained from the latest surveillance capsule report, WCAP-16382-NP 
[Ref. 8], and was originally documented in the Capsule Y report, WCAP-14532 
[Ref. 9].The heat treatment of the unirradiated surveillance materials is presented in Table 4-3. The data in Table 4-3 was obtained from the unirradiated surveillance program report, WCAP-1 1381 [Ref. 3], Appendix A.Capsule Z was removed after 18.48 EFPY of plant operation.

The specimens and spacer blocks were carefully removed, inspected for identification number, and checked against the master list in WCAP-11381 
[Ref. 3]. All items were in their proper locations.
Examination of the thermal monitors indicated that none of the melting point monitors had melted. Based on this examination, the maximum temperature to which the specimens were exposed was less than 579&deg;F (304-C).The Charpy impact tests were performed per ASTM Specification E23-07a [Ref. 10] 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.
Note that the instrumented Charpy data is for information only. The Instron Impulse system has not been calibrated to ASTM Standard E2298-09 [Ref. 11 ], so the instrumented energy, load, time, and stress data are considered for information only. With this system, load-time and energy-time signals can be recorded in addition to the standard measurement of Charpy energy. The load signal data acquisition rate was 819 kHz with data acquired for 10 ms. For some of the tests, a low-pass filter was used to condition the load signal. From the load-time curve, the load of general yielding (Fgy), the time to general yielding, the maximum load (Fm), and the time to maximum load 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 brittle fracture load (Fbf). The termination of the fast load drop is identified as the arrest load (Fa). Fgy, Fm, Fbf, and Fa were determined per the guidance in ASTM Standard E2298-09.
Note that some of the signals were filtered for the instrumented Charpy testing. Although this is not recommended in ASTM Standard E2298-09, the instrumented Charpy data is reported for information only; thus, there is no significant effect on the results contained in this report.The energy at maximum load (Win) was determined by integrating 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 (Wp) is the difference between the total energy to fracture (W,) and the energy at maximum load (Win).WCAP- 17343-NP March 2011 Revision 0 5-2 Westinghouse Non-Proprietary Class 3 The yield stress (ay) was calculated from the three-point bend formula having the following expression 
[Ref. 12]: L SF B(WLa)2 C (Eqn. 5-1)where L = distance between the specimen supports in the impact testing machine; B = the width of the specimen measured parallel to the notch; W = height of the specimen, measured perpendicularly to the notch; a = notch depth. The constant C is dependent on the notch flank angle (tp), notch root radius (p)and the type of loading (i.e., pure bending or three-point bending).
In three-point bending, for a Charpy specimen in which 9 = 450 and p = 0.010 in., Equation 5-1 is valid with C = 1.21.Therefore, (for L = 4W), L 3.305 F,W S B(W-a)2 1.21 B(W-a)2  (Eqn. 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: crY = 33.3 FV (Eqn. 5-3)where Oy is in units of psi and Fgy 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.Normalized energies for Wt, Win, and Wp were calculated per the cross-sectional area (A) under the notch of the Charpy specimens:
A = B(W -a) = 0.1241 sq. in. (Eqn. 5-4)Percent shear was determined from post-fracture photographs using the ratio-of-areas methods in compliance with ASTM E23-07a [Ref. 10] and A370-09 [Ref. 13]. 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 model 4400 screw-driven tensile machine (Model 1115). Testing met ASTM Specifications E8-09 [Ref. 14] and E21-09 [Ref. 15] except for some minor deviations that do not have any significant effect on the results provided in this report.Elevated test temperatures were obtained with a three-zone electric resistance split-tube furnace with a 9-inch hot zone. Specimens were soaked at temperature 
(+/-5&deg;F) for a minimum of 20 minutes before testing. All tests were conducted in air. The specimens were round 0.25-inch diameter with a 1.25-inch reduced section. Load was applied through a clevis and pin connection.
WCAP-17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 5-3 The yield load, ultimate load, fracture load, uniform elongation, and elongation at fracture were determined directly from the load-extension curve. The yield strength, ultimate tensile 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 CHARPY V-NOTCH IMPACT TEST RESULTS The results of the Charpy V-notch impact tests performed on the various materials contained in Capsule Z, which received a fluence of 4.16 x 10'9 n/cm 2 (E > 1.0 MeV) in 18.48 EFPY of operation, are presented in Tables 5-1 through 5-8 and are compared with the unirradiated and previously withdrawn capsule results as shown in Figures 5-1 through 5-12. The unirradiated and previously withdrawn capsule results were taken from WCAP-11381 
[Ref. 3], WCAP-13007 
[Ref. 16], WCAP-14532 
[Ref. 9], WCAP-15159 
[Ref. 17], and WCAP-16382-NP 
[Ref. 8].The transition temperature increases and changes in upper-shelf energies for the Capsule Z materials are summarized in Table 5-9 and led to the following results:* Irradiation of the reactor vessel Lower Shell Plate B8628-1 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 67.8&deg;F and an irradiated 50 ft-lb transition temperature of 106.8&deg;F. This results in a 30 ft-lb transition temperature increase of 59.0&deg;F and a 50 ft-lb transition temperature increase of 61.4&deg;F for the longitudinally oriented specimens." Irradiation of the reactor vessel Lower Shell Plate B8628-1 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 103.9&deg;F and an irradiated 50 ft-lb transition temperature of 140. I&deg;F. This results in a 30 ft-lb transition temperature increase of 75.3&deg;F and a 50 ft-lb transition temperature increase of 70.0&deg;F for the transversely oriented specimens.
* Irradiation of the Surveillance Program Weld Metal (Heat # 87005) Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 2.1 lF and an irradiated 50 ft-lb transition temperature of 48.3&deg;F. This results in a 30 ft-lb transition temperature increase of 21.3&deg;F and a 50 ft-lb transition temperature increase of 37.2&deg;F.* Irradiation of the Heat-Affected Zone (HAZ) Material Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of -75.1 &deg;F and an irradiated 50 ft-lb transition temperature of -41.2&deg;F.This results in a 30 ft-lb transition temperature increase of 8.6&deg;F and a 50 ft-lb transition temperature increase of 11.2&deg;F.* The average upper-shelf energy of the Lower Shell Plate B8628-1 (longitudinal orientation) did not change after irradiation to 4.16 x 1019 n/cm 2 (E > 1.0 MeV). This results in an irradiated average upper-shelf energy of 89.0 ft-lb for the longitudinally oriented specimens.
WCAP-17343-NP March 2011 Revision 0 5-4 Westinghouse Non-Proprietary Class 3* The average upper-shelf energy of the Lower Shell Plate B8628-1 (transverse orientation) resulted in an average energy decrease of 2.0 ft-lb after irradiation to 4.16 x 101 9 n/cm 2 (E > 1.0 MeV). This results in an irradiated average upper-shelf energy of 68.0 ft-lb for the transversely oriented specimens.
* The average upper-shelf energy of the weld metal Charpy specimens resulted in an average energy decrease of 2.0 ft-lb after irradiation to 4.16 x 10'9 n/cm 2 (E > 1.0 MeV). This results in an irradiated average upper-shelf energy of 90.0 ft-lb for the weld metal specimens.
* The average upper-shelf energy of the HAZ Material Charpy specimens resulted in an average energy increase of 6.0 ft-lb after irradiation to 4.16 x 1019 n/cm 2 (E > 1.0 MeV). This results in an irradiated average upper-shelf energy of 112.0 ft-lb for the HAZ Material." Comparisons of the measured 30 ft-lb shift in transition temperature values and upper-shelf energy decreases to those predicted by Regulatory Guide 1.99, Revision 2 [Ref. 1] for the Vogtle Unit 2 reactor vessel surveillance materials are presented in Table 5-10.The fracture appearance of each irradiated Charpy specimen from the various materials is shown in Figures 5-13 through 5-16. The fractures show an increasingly ductile or tougher appearance with increasing test temperature.
Load-time records for the individual instrumented Charpy specimens are contained in Appendix B.All beltline materials exhibit a more than adequate upper-shelf energy level for continued safe plant operation and are predicted to maintain an upper-shelf energy greater than 50 ft-lb through end-of-license (36 EFPY) and end-of-license renewal (57 EFPY) as required by 10 CFR 50, Appendix G [Ref. 2]. This evaluation can be found in Appendix E.WCAP-17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 5-5 5.3 TENSILE TEST RESULTS The results of the tensile tests performed on the various materials contained in Capsule Z irradiated to 4.16 x 10'9 n/cm 2 (E > 1.0 MeV) are presented in Table 5-11 and are compared with unirradiated results as shown in Figures 5-17 through 5-19.The results of the tensile tests performed on the Lower Shell Plate B8628-1 (longitudinal orientation) indicated that irradiation to 4.16 x 101 9 n/cm 2 (E > 1.0 MeV) caused increases in the 0.2 percent offset yield strength and the ultimate tensile strength when compared to unirradiated data [Ref. 3]. See Figure 5-17 and Table 5-11.The results of the tensile tests performed on the Lower Shell Plate B8628-1 (transverse orientation) indicated that irradiation to 4.16 x l0o9 n/cm 2 (E > 1.0 MeV) caused increases in the 0.2 percent offset yield strength and the ultimate tensile strength when compared to unirradiated data [Ref. 3]. See Figure 5-18 and Table 5-11.The results of the tensile tests performed on the surveillance weld metal indicated that irradiation to 4.16 x 10"9 n/cm 2 (E > 1.0 MeV) caused increases in the 0.2 percent offset yield strength and the ultimate tensile strength when compared to unirradiated data [Ref. 3]. See Figure 5-19 and Table 5-11.The fractured tensile specimens for the Lower Shell Plate B8628-1 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 5-28.5.4 1/2T COMPACT TENSION SPECIMEN TESTS Per the surveillance capsule testing contract, the 1/2T Compact Tension Specimens were not tested and are being stored at the Westinghouse Research and Technology Unit.WCAP- 17343-NP March 2011 Revision 0 5-6 Westinghouse Non-Proprietary Class 3 Table 5-1 Charpy V-notch Data for the Vogtle Unit 2 Lower Shell Plate B8628-1 Irradiated to a Fluence of 4.16 x 10'9 n/cm 2 (E > 1.0 MeV) (Longitudinal Orientation)

==6.1 INTRODUCTION==

This section describes a discrete ordinates S. transport analysis performed for the Vogtle 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 Z, withdrawn at the end of the fourteenth plant operating cycle, is provided.
In addition, to provide an up-to-date data base applicable to the Vogtle Unit 2 reactor, the sensor sets from the previously withdrawn capsules (U, Y, X, and W) 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 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 E853-01, "Analysis and Interpretation of Light-Water Reactor Surveillance Results," [Ref. 18] recommends 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 E693-01, "Standard Practice for Characterizing Neutron Exposures in Iron and Low Alloy Steels in Terms of Displacements per Atom" [Ref. 19]. 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 Reactor Vessel Materials" [Ref. 1].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 of Regulatory Guide 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence" [Ref. 20]. Additionally, the methods used to develop the calculated pressure vessel fluence are consistent with the NRC-approved methodology described in WCAP-14040-A, Revision 4, "Methodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves," May 2004 [Ref. 21].WCAP-17343-NP March 2011 Revision 0 6-2 Westinghouse Non-Proprietary Class 3 6.2 DISCRETE ORDINATES ANALYSIS The arrangement of the surveillance capsules in the Vogtle Unit 2 reactor vessel is shown in Figure 4-1.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 58.50, 61.00, 121.5', 238.5', 241.00, and 301.50 as shown in Figure 4-1. These full-core positions correspond to the following octant symmetric locations represented in Figures 6-2 and 6-3: 290 from the core cardinal axes (for the 61.0' and 241.0' dual surveillance capsule holder locations found in octants with a 22.50 neutron pad segment) and 31.5' from the core cardinal axes (for the 121.5' and 301.50 single surveillance capsule holder locations found in octants with a 20.00 neutron pad segment, and for the 58.5' and the 238.5' dual surveillance capsule holder locations found in octants with a 22.50 neutron pad segment).
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 Vogtle 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: (p(r,0, z) = (p(r,0)
* p((r, z) (Eqn. 6-1)(p(r)where 4(r,O,z) is the synthesized three-dimensional neutron flux distribution, &#xfd;(r,0) is the transport solution in r,0 geometry, 4(rz) is the two-dimensional solution for a cylindrical reactor model using the actual axial core power distribution, and 4(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 Vogtle Unit 2.For the Vogtle Unit 2 transport calculations, the r,0 models depicted in Figures 6-1 through 6-3 were utilized since, with the exception of the neutron pads, the reactor is octant symmetric.
These r,0 models include the core, the reactor internals, the neutron pads -including explicit representations of an octant not containing surveillance capsules and octants with surveillance capsules at 29.00 and 31.50, the pressure vessel cladding and vessel wall, the insulation external to the pressure vessel, and the primary biological shield wall. These models formed the basis for the calculated results and enabled making comparisons to the surveillance capsule dosimetry evaluations.
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, WCAP-17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 6-3 water, and miscellaneous core structures such as fuel assembly grids, guide tubes, et cetera. The geometric mesh description of the r,0 reactor models consisted of 183 radial by 99 azimuthal intervals.
Mesh sizes were chosen to assure that proper convergence of the inner iterations was achieved on a pointwise basis. The pointwise inner iteration flux convergence criterion utilized in the r,0 calculations was set at a value of 0.001.The rz model used for the Vogtle Unit 2 calculations is shown in Figure 6-4 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 below the lower core plate to above the upper core plate. 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 153 radial by 188 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 pointwise basis.The pointwise inner iteration flux convergence criterion utilized in the rz calculations was also set at a value of 0.001.The one-dimensional radial model used in the synthesis procedure consisted of the same 153 radial mesh intervals included in the rz model. Thus, radial synthesis factors could be determined on a meshwise basis throughout the entire geometry.The core power distributions used in the plant-specific transport analysis were provided by the Nuclear Fuels Division of Westinghouse for each of the first fifteen fuel cycles at Vogtle Unit 2. Specifically, the data utilized included cycle-dependent fuel assembly initial enrichments, burnups, 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 burnup 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.
All of the transport calculations supporting this analysis were carried out using the DORT discrete ordinates code Version 3.2 [Ref. 22] and the BUGLE-96 cross-section library [Ref. 23]. 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 S 1 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 6-6. 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 octant symmetric surveillance capsule positions, i.e., for the 29.00 dual capsule, 31.5' dual capsule, and 31.50 single capsule. These WCAP-17343-NP March 2011 Revision 0 6-4 Westinghouse Non-Proprietary Class 3 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 Table 6-2 for the reactor vessel inner radius at four azimuthal locations.
The vessel data given in Table 6-2 were taken at the clad/base metal interface, and thus, represent maximum calculated exposure levels on the vessel.From the data provided in Table 6-2 it is noted that the peak clad/base metal interface vessel fluence (E > 1.0 MeV) at the end of the fourteenth fuel cycle (i.e., after 18.48 EFPY of plant operation) was 1.00 x 1019 n/cm 2 at the 450 azimuthal location.
This peak clad/base metal interface vessel fluence of 1.00 x 10'9 n/cm 2 was also reported in the Vogtle Unit 2 Cycle 14 ex-vessel neutron dosimetry analysis report [Ref. 24].Both calculated fluence (E > 1.0 MeV) and dpa data are provided in Tables 6-1 and 6-2. These data tabulations include both plant- and fuel-cycle-specific calculated neutron exposures at the end of the fourteenth fuel cycle as well as future projections to 19.94, 24, 28, 32, 36, 40, 44, 48, 54, and 60 EFPY.The calculations account for uprates from 3411 MWt to 3565 MWt that occurred at the onset of Cycle 4 and from 3565 MWt to 3626 MWt that occurred at the onset of Cycle 14. The projections were based on the assumption that the core power distributions and associated plant operating characteristics from Cycle 15 were representative of future plant operation.
The future projections are also based on the current reactor power level of 3626 MWt.Radial gradient information applicable to fast (E > 1.0 MeV) neutron fluence and dpa are given in Tables 6-3 and 6-4, respectively.
The data, based on the cumulative integrated exposures from Cycles 1 through 14, 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 6-3 and 6-4.The calculated fast neutron exposures for the five surveillance capsules withdrawn from the Vogtle Unit 2 reactor are provided in Table 6-5. These assigned neutron exposure levels are based on the plant- and fuel-cycle-specific neutron transport calculations performed for the Vogtle Unit 2 reactor.From the data provided in Table 6-5, Capsule Z received a fluence (E > 1.0 MeV) of 4.16 x 1019 n/cm 2 after exposure through the end of the fourteenth fuel cycle (i.e., after 18.48 EFPY of plant operation).
Updated lead factors for the Vogtle Unit 2 surveillance capsules are provided in Table 6-6. 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 6-6, the lead factors for capsules that have been withdrawn from the reactor (U, Y, X, W, and Z) were based on the calculated fluence values for the irradiation period corresponding to the time of withdrawal for the individual capsules.
The lead factor for Capsule V, which was withdrawn at the end of Cycle 14 and stored in the spent fuel pool, corresponds to the calculated fluence values at the end of Cycle 14, the last completed fuel cycle for Vogtle Unit 2.WCAP- 17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 6-5 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 serve 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 Z, that was withdrawn from Vogtle Unit 2 at the end of the fourteenth fuel cycle, is summarized below.j~v ~Reaction Raites (rps/atom)

The measured-to-calculated (M/C) reaction rate ratios for the Capsule Z threshold reactions range from 0.80 to 1.01, and the average M/C ratio is 0.93 +/- 9.1% (1o). This direct comparison falls well within the+/- 20% criterion specified in Regulatory Guide 1.190; furthermore, it is consistent with the full set of comparisons given in Appendix A for all measured dosimetry removed to date from the Vogtle Unit 2 reactor. These comparisons validate the current analytical results described in Section 6.2; therefore, the calculations are deemed applicable for Vogtle Unit 2.6.4 CALCULATIONAL UNCERTAINTIES The uncertainty associated with the calculated neutron exposure of the Vogtle Unit 2 surveillance capsule and reactor pressure vessel is based on the recommended approach provided in Regulatory Guide 1.190.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.

: 4. Comparisons of the plant-specific calculations with all available dosimetry results from the Vogtle Unit 2 surveillance program.The first phase of the methods qualification (PCA comparisons) addressed the adequacy of basic transport calculation and dosimetry evaluation techniques andassociated 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 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 Vogtle Unit 2 analysis was established from results of these three phases of the methods qualification.
The fourth phase of the uncertainty assessment (comparisons with Vogtle 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 Vogtle 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.

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" [Ref. A-1]. 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.A.1.1 Sensor Reaction Rate Determinations In this section, the results of the evaluations of the five neutron sensor sets analyzed to date as part of the Vogtle Unit 2 Reactor Vessel Materials Surveillance Program are presented.
The capsule designation, location within the reactor, and time of withdrawal of each of these dosimetry sets were as follows: Capsule ID AzimuthalLocation, Tinmei :Irradiation Time U 31.5' Dual End of Cycle 1 1.20 Y 29.00 Dual End of Cycle 4 4.98 X 31.50 Dual End of Cycle 6 7.78 W 31.50 Single End of Cycle 10 13.29 Z 31.50 Single End of Cycle 14 18.48 The azimuthal locations included in the above tabulation represent the first octant equivalent azimuthal angle of the geometric center of the respective surveillance capsules.The passive neutron sensors included in the evaluations of surveillance Capsules U, Y, X, W, and Z are summarized as follows: WCAP-17343-NP March 2011 Revision 0 A-2 Westinghouse Non-Proprietary Class 3 A-2 Westinghouse Non-Proprietary Class 3 Since all of the dosimetry monitors were located at the radial center of the material test specimen array, radial 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 does 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: 0 the measured specific activity of each monitor,* the physical characteristics of each monitor,* the operating history of the reactor,* the energy response of each monitor, and 0 the neutron energy spectrum at the monitor location.Results from the radiometric counting of the neutron sensors from Capsules U, Y, X, and W are documented in References A-2 through A-5, respectively.
The radiometric counting of the sensors from Capsule Z was carried out by Pace Analytical Services, Inc. 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, these 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.The irradiation history of the reactor over the irradiation periods experienced by Capsules U, Y, X, W, and Z was based on the monthly power generation of Vogtle Unit 2 from initial reactor criticality through the end of the dosimetry evaluation period. 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, Y, X, W, and Z is given in Table A-2.WCAP-17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 A-3 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 No F Y Z P1 Cj [V -e'l/] [e-d"']P,.ef 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/g).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.Pi = Average core power level during irradiation period j (MW).Pref = Maximum or reference power level of the reactor (MW).CJ = Calculated ratio of 4(E > 1.0 MeV) during irradiation period j to the time weighted average 4(E > 1.0 MeV) over the entire irradiation period.= Decay constant of the product isotope (1/sec).= Length of irradiation period j (sec).td = Decay time following irradiation periodj (sec).and the summation is carried out over the total number of monthly intervals comprising the irradiation period.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 WCAP- 17343-NP March 2011 Revision 0 A-4 Westinghouse Non-Proprietary Class 3 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 2 3 8 U measurements to account for the presence of 2 3 5 U impurities in the sensors as well as to adjust for the build-in of plutonium isotopes over the course of the irradiation.
Corrections were also made to the 2 3 8 U and 2 3 7 Np 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 Vogtle Unit 2 fission sensor reaction rates are summarized as follows: KJCorrecionr Capsule U CapsuleXY Capsule Xj ICapsule W Capsule Z 235U Impurity/Pu Build-in in 2 3 8 U 0.870 0.841 0.817 0.777 0.737 2 3 8 U(y,f) 0.966 0.967 0.966 0.969 0.969 Net 2 3 8 U Correction 0.841 0.813 0.789 0.753 0.714 2 3 7 Np(y,f) 0.990 0.990 0.990 0.991 0.991 These factors were applied in a multiplicative fashion to the decay corrected uranium and neptunium fission sensor reaction rates.Results of the sensor reaction rate determinations for Capsules U, Y, X, W, and Z are given in Table A-4.In Table A-4, 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. The fission sensor reaction rates are listed both with and without the applied corrections for 2 3 8 U 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 &#xfd;(E > 1.0 MeV) or dpa/s 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 reaction rate data, dosimetry reaction cross sections, and the calculated neutron energy spectrum within their respective uncertainties.
For example, Rj_++/-6R., =-g +8g. )((Pg _+86 )g relates a set of measured reaction rates, Ri, to a single neutron spectrum, k' through the multigroup dosimeter reaction cross section, mig, 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.
WCAP- 17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 A-5 For the least squares evaluation of the Vogtle Unit 2 surveillance capsule dosimetry, the FERRET code [Ref. A-6] 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 (4(E > 1.0 MeV) and dpa) along with associated uncertainties for the five in-vessel capsules analyzed 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 Vogtle 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 [Ref. A-7]. The SNLRML library is an evaluated dosimetry reaction cross-section compilation recommended for use in LWR evaluations by ASTM Standard E1018, "Application of ASTM Evaluated Cross-Section Data File, Matrix E706 (1IB)" [Ref. A-8].The uncertainties associated with the measured reaction rates, dosimetry cross sections, and calculated neutron spectrum 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 E944,"Application of Neutron Spectrum Adjustment Methods in Reactor Surveillance" [Ref. A-9].The following provides a summary -of the uncertainties associated with the least squares evaluation of the Vogtle Unit 2 surveillance capsule sensor sets.WCAP-17343-NP March 2011 Revision 0 A-6 Westinghouse Non-Proprietary Class 3 A-6 Westinghouse Non-Proprietary Class 3 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 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:

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 multigroup 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 Vogtle Unit 2 surveillance program, the following uncertainties in the fission spectrum averaged cross sections are provided in the SNLRML documentation package.WCAP- 17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 A-7 Westinghouse Non-Proprietary Class 3 A-7 Reactionua Unlcertainty 6 3 Cu(n,u)6&deg;Co 4.08-4.16%

These tabulated ranges provide an indication of the dosimetry cross-section the sensor sets used in LWR irradiations.
uncertainties associated with Calculated Neutron Snectrum 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:-R 2 +Rg *RgP where Rn specifies an overall fractional normalization uncertainty and the fractional uncertainties Rg and Rg, specify additional random groupwise uncertainties that are correlated with a correlation matrix given by: P [gIf-Olg,, + +/-Oe-H where H = (g -g')2 27,2 WCAP-17343-NP March 2011 Revision 0 A-8 Westinghouse Non-Proprietary Class 3 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 Vogtle Unit 2 calculated spectra was as follows: Flux Normalization Uncertainty (Rn) 15%Flux Group Uncertainties (Rg, Rg,)(E > 0.0055 MeV) 15%(0.68 eV < E < 0.0055 MeV) 25%(E < 0.68 eV) 50%Short Range Correlation (0)(E > 0.0055 MeV) 0.9 (0.68 eV < E < 0.0055 MeV) 0.5 (E < 0.68 eV) 0.5 Flux Group Correlation Range (y)(E > 0.0055 MeV) 6 (0.68 eV < E < 0.0055 MeV) 3 (E < 0.68 eV) 2 A.1.3 Comparisons of Measurements and Calculations Results of the least squares evaluations of the dosimetry from the Vogtle Unit 2 surveillance capsules withdrawn to date are provided in Tables A-5 and A-6. 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.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% at the 1 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% for neutron flux (E > 1.0 MeV) and 7-8% for iron atom displacement rate. Again, the uncertainties from the least squares evaluation are at the l level.WCAP- 17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 A-9 Further comparisons of the measurement results (from Tables A-5 and A-6) 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&#xfd;(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% 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 M/C comparisons for fast neutron reactions range from 0.80 to 1.27 for the 25 samples included in the data set.The overall average M/C ratio for the entire set of Vogtle Unit 2 data is 1.07 with an associated standard deviation of 11.6%.In the comparisons of best-estimate and calculated fast neutron exposure parameters, the corresponding BE/C comparisons for the capsule data sets range from 0.92 to 1.20 for neutron flux (E > 1.0 MeV) and from 0.92 to 1.18 for iron atom displacement rate. The overall average BE/C ratios for neutron flux (E > 1.0 MeV) and iron atom displacement rate are 1.06 with a standard deviation of 10.2% and 1.05 with a standard deviation of 9.7%, 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 Vogtle Unit 2 reactor pressure vessel.WCAP- 17343-NP March 2011 Revision 0 A-10 Westinghouse Non-Proprietary Class 3 Table A-I Nuclear Parameters Used in the Evaluation of Neutron Sensors Reaction ofR TargetAtoM 90% Rsn P Fission Yield-Monitor'NMaterial.

Westinghouse Non-Proprietary Class 3 C-1 APPENDIX C CHARPY V-NOTCH PLOTS FOR EACH CAPSULE USING SYMMETRIC HYPERBOLIC TANGENT CURVE-FITTING METHOD Contained in Table C-1 are the upper-shelf energy (USE) values that are used as input for the generation of the Charpy V-notch plots using CVGRAPH, Version 5.3. The definition for USE is given in ASTM E 185-82 [Ref. C-I], 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 typically 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, excluding any values that are deemed outliers using engineering judgment.
Hence, the Capsule Z USE values reported in Table C-I were determined by applying this methodology to the Charpy data tabulated in Tables 5-1 through 5-4 of this report. USE values documented in Table C-I for the unirradiated material, as well as Capsules U, Y, X, and W, were imported directly from Reference C-2.The USE values reported in Table C-I were used in generation of the Charpy V-notch curves.The lower-shelf energy values were fixed at 2.2 ft-lb for all cases. The lower-shelf Lateral Expansion values were fixed at 0.0 mils in order to be consistent with the previous capsule analysis [Ref. C-2].Table C-1 Upper-Shelf Energy Values (ft-lb) Fixed in CVGRAPH>Capsule Unirradiated U y X' W ~z Lower Shell Plate B8628-1 89 99 100 86 84 89 Longitudinal Orientation Lower Shell Plate B8628-1 70 79 73 65 69 68 Transverse Orientation Surveillance Program Weld Metal 92 98 86 87 87 90 (Heat # 87005)HAZ Material 106 122 114 99 100 112 CVGRAPH Version 5.3 plots of all surveillance data are provided in this appendix, on the pages following the reference list.WCAP-17343-NP March 2011 Revision 0 C-2 Westinghouse Non-Proprietary Class 3 C.1 REFERENCES C-1 ASTM E185-82, Standard Practice for Conducting Surveillance Tests for Light-Water Cooled Nuclear Power Reactor Vessels, E706(IF), ASTM, 1982.C-2 WCAP-16382-NP, Revision 0, Analysis of Capsule Wfrom the Southern Nuclear Operating Company, Vogtle Unit 2 Reactor Vessel Radiation Surveillance Program, T.

Westinghouse Non-Proprietary Class 3 D-1 APPENDIX D VOGTLE UNIT 2 SURVEILLANCE PROGRAM CREDIBILITY EVALUATION D.1 INTRODUCTION Regulatory Guide 1.99, Revision 2 [Ref. 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 upper-shelf energy 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 five surveillance capsules removed from the Vogtle Unit 2 reactor vessel and tested. To use these surveillance data sets, they must be shown to be credible.
In accordance with Regulatory Guide 1.99, Revision 2, the credibility of the surveillance data will be judged based on five criteria.The purpose of this evaluation is to apply the credibility requirements of Regulatory Guide 1.99, Revision 2, to the Vogtle 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" [Ref. D-2], as follows: "the region of the reactor vessel (shell material including welds, heat affected zones, and plates orforgings) that directly surrounds the effective height of the active core and adjacent regions of the reactor vessel that are predicted to experience sufficient neutron radiation damage to be considered in the selection of the most limiting material with regard to radiation damage." WCAP- 17343-NP March 2011 Revision 0 D-2 Westinghouse Non-Proprietary Class 3 The Vogtle Unit 2 reactor vessel consists of the following beltline region materials: " Intermediate Shell Plates R4-1, R4-2, and R4-3" Lower Shell Plates B8825-1, R8-1, and B8628-1* Intermediate Shell Longitudinal Weld Seams 101-124 A, B, and C (fabricated with weld wire Heat # 87005, Linde 0091 flux, Lot # 0145)" Lower Shell Longitudinal Weld Seams 10 1-142 A, B, and C (fabricated with weld wire Heat # 87005, Linde 0091 flux, Lot # 0145)* Intermediate to Lower Shell Circumferential Weld Seam 101-171 (fabricated with weld wire Heat # 87005, Linde 124 flux, Lot # 1061)The Vogtle Unit 2 surveillance program utilizes longitudinal and transverse test specimens from Lower Shell Plate B8628-1. The surveillance weld metal was fabricated with weld wire Heat # 87005, Linde 124 flux, Lot # 1061.At the time when the surveillance program material was selected, it was believed that copper and phosphorus were the elements most important to embrittlement of reactor vessel steels. Lower Shell Plate B8628-1 had the highest initial RTNDT and one of the lowest initial USE values of all plate materials in the beltline region. In addition, Lower Shell Plate B8628-1 had approximately the same copper and phosphorus content of the other beltline plate materials.
Based on the highest initial RTNDT and one of the lowest initial USE values of all plate materials in the beltline region, Lower Shell Plate B8628-1 was chosen for the surveillance program.The circumferential weld has the same heat number as all the beltline longitudinal welds, but a different flux. The circumferential weld had the lower initial RTNDT of the two flux types. However, both welds had low initial RTNDT values and approximately the same copper and phosphorus content. the initial USE of the circumferential weld was approximately 60 ft-lbs lower than the initial USE of the beltline longitudinal weld seams. Thus, the circumferential weld was selected based on the lower USE value.Based on the above discussion and the methodology in use at the time the program was developed, the Vogtle Unit 2 surveillance material meets the intent of Criterion 1.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.
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 Vogtle Unit 2 surveillance materials unambiguously.
Hence, the Vogtle Unit 2 surveillance program meets this criterion.
WCAP- 17343-NP March 2011 Revision 0 Westinghouse Non-Proprietary Class 3 D-3 Westinghouse Non-Proprietary Class 3 D-3 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 should normally 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 E185-82 [Ref. D-3].The functional form of the least squares method as described in Regulatory Position 2.1 will be 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 17'F for the plate.The Vogtle Unit 2 Lower Shell Plate B8628-1 and surveillance weld material will be evaluated for credibility.
The weld is made from weld wire Heat # 87005; Vogtle Unit 2 does not have a sister plant that shares the same weld wire heat and thus does not utilize data from other surveillance programs.Therefore, the method of Regulatory Guide 1.99, Revision 2 will be followed for determining credibility of the weld as well as the plate material.WCAP- 17343-NP March 2011 Revision 0 D-4 Westinghouse Non-Proprietary Class 3 Credibility Assessment:
Since all surveillance data is from one vessel (Vogtle Unit 2), the measured ARTNDT and fluence factor (FF) should be used to calculate the chemistry factors to determine if the Vogtle Unit 2 surveillance material test results are credible.The chemistry factors for the Vogtle Unit 2 surveillance plate and weld material contained in the surveillance program were calculated in accordance with Regulatory Guide 1.99, Revision 2, Position 2.1 and are presented in Table D-1. The scatter of ARTNDT values about the functional form of a best-fit line drawn as described in Regulatory Position 2.1 is presented in Table D-2.Table D-1 Calculation of Interim Chemistry Factors for the Credibility Evaluation using Vogtle Unit 2 Surveillance Capsule Data MaeilCpue Capsule f F, ARTNDT FFI*ARTNDT F (x 11 9 n/cm FF (I U 0.356 0.715 2.0 1.43 0.511 Y 1.12 1.032 5.8 5.98 1.064 Lower Shell Plate B8628-1 (Longitudinal)

Table D-2 indicates that six of the ten surveillance data points fall outside the +/- 1(y of 17F scatter band for surveillance base metals; therefore, the plate data is deemed "not credible" per the third criterion.
Table D-2 indicates that zero of the five surveillance data points falls outside the +/- lcr of 28&deg;F scatter band for surveillance weld materials; therefore, the surveillance weld data is deemed "credible" per the third criterion.
Note that although Lower Shell Plate B8628-1 did not meet Criterion 3, both materials (Lower Shell Plate B8628-1 and the surveillance weld material) may still be used in determining the upper-shelf energy decrease in accordance with Regulatory Guide 1.99, Revision 2, Position 2.2.WCAP-17343-NP March 2011 Revision 0 D-6 Westinghouse Non-Proprietary Class 3 D-6 Westinghouse Non-Proprietary Class 3 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 pads.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 Vogtle Unit 2 surveillance program does not contain correlation monitor material.
Therefore, this criterion is not applicable to the Vogtle 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 Vogtle Unit 2 surveillance data is deemed credible for the weld specimens and non-credible for the plate specimens.

E-l], the Charpy upper-shelf energy (USE) is assumed to decrease as a function of fluence and copper content as indicated in Figure 2 of the Guide (Figure E-I of this appendix) when surveillance data is not used. Linear interpolation is permitted.
In addition, if surveillance data is to be used, the decrease in upper-shelf energy may be obtained by plotting the reduced plant surveillance data on Figure 2 of the Guide (Figure E-I of this appendix) and fitting the data with a line drawn parallel to the existing lines as the upper bound of all the data. This line should be used in preference to the existing graph.The 36 EFPY (end-of-license) and 57 EFPY (end-of-license renewal) upper-shelf energy of the vessel materials can be predicted using the corresponding 1/4T fluence projection, the copper content of the beltline materials and/or the results of the capsules tested to date using Figure 2 in Regulatory Guide 1.99, Revision 2. The maximum vessel clad/base metal interface fluence value was used to determine the corresponding l/4T fluence value at 36 and 57 EFPY. Note that the maximum fluence value associated with 57 EFPY was calculated based on the linear interpolation of the maximum fluence values at 54 EFPY and 60 EFPY.The Vogtle Unit 2 reactor vessel beltline region minimum thickness is 8.625 inches. Calculation of the 1/4T vessel surface fluence values at 36 and 57 EFPY for the beltline materials is shown as follows: Maximum Vessel Fluence @ 36 EFPY 2.00 x 1019 n/cm 2 (E > 1.0 MeV)1/4T Fluence @ 36 EFPY = (2.00 x 1019 n/cm 2)
