SUMMARY

The purpose of this report is to document the testing results of surveillance Capsule V from Braidwood Unit 1. Capsule V was removed at 17.69 effective full-power years (EFPY) and stored in the spent fuel pool. Post-irradiation mechanical tests of the Charpy V-notch and tensile specimens were performed during Cycle 19 to satisfy license renewal commitments. A fluence evaluation utilizing the neutron transport and dosimetry cross-section libraries was derived from the Evaluated Nuclear Data File (ENDF) database (specifically, ENDF/B-VI). Capsule V received a fluence of 3.71 x 10 19 n/crrl (E > 1.0 MeV) after irradiation to 17 .69 EFPY. The peak clad/base metal interface vessel fluence after 57 EFPY (end-of-license extension) of plant operation is projected to be 3.22 x 10 19 n/cm2 (E > 1.0 MeV). This evaluation led to the following conclusions:. 1) The measured percent decreases in upper-shelf energy for the surveillance forging and weld materials contained in Braidwood Unit 1 Capsule V are less than the U.S. NRC Regulatory Guide 1.99, Revision 2 [Ref. 1] predictions. 2) With consideration of surveillance data, all beltline and extended beltline materials exhibit adequate upper-shelf energy levels for continued safe plant operation and are predicted to maintain an upper-shelf energy greater than 50 ft-lb through end-of-license extension (57 EFPY) as required by 10 .CFR 50, Appendix G [Ref. 2]. The upper-shelf energy evaluation is presented in Appendix D. 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-18092-NP May2016 Revision 1

SUMMARY

OF RESULTS The analysis of the reactor vessel materials contained in surveillance Capsule V, the fourth capsule removed and tested from the Braidwood Unit 1 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 6.02, Charpy V-notch plots for Capsule V and previous capsules, along with the program input data.

Capsule V received an average fast neutron fluence (E > 1.0 MeV) of 3.71 x 1019 n/cm2 after 17 .69 effective full-power .years (EFPY) of plant operation.
Irradiation of the reactor vessel Lower Shell-Forging [49D867/49C813]-1-1 Charpy specimens, oriented with the longitudinal axis of the specimen parallel to th~ major working direction (tangential orientation), resulted in an irradiated 30 ft-lb transition temperature of -24.6°F and an irradiated 50 ft-lb transition temperature of 6.7°F. This results in a 30 ft-lb transition temperature increase of 5L3°F and a 50 ft-lb transition temperature increase of 47.8°F for the tangentially oriented specimens.
Irradiation of the reactor vessel Lower Shell Forging [49D867/49C813]-1-1 Charpy specimens, oriented with the longitudinal l:J.Xis of the specimen perpendicular to the major working direction (axial orientation), resulted in an irradiated 30 ft-lb transition temperature of -8.0°F and an irradiated 50 ft-lb transition temperature of 26.9°F. This results in a 30 ft-lb transition temperature increase of 39.7°F and a 50 ft-lb transition temperature increase of 42.7°F for the axially oriented specimens.
Irradiation of the Surveillance Program Weld Material (Heat# 442011) Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 36.7°F and an irradiated 50 ft-lb transition temperature of 104.3°F. This results in a 30 ft-lb transition temperature increase of 62.8°F and a 50 ft-lb transition temperature increase of79.1°F.
Irradiation of the Heat-Affected Zone (HAZ) Material Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of -66.0°F and an irradiated 50 ft-lb transition temperature of -16.6°F.

This results in a 30 ft-lb transition temperature increase of l 71.0°F and a 50 ft-lb transition temperature increase of 119.1°F.

The average upper-shelf energy .of Lower Shell Forging [49D867/49C813]-1-1 (tangential orientation) resulted in an average energy decrease of 3 ft-lb after irradiation. This decrease results in an irradiated average upper-shelf energy of 163 ft-lb for the tangentially oriented specimens.
The average upper-shelf energy of Lower Shell Forging [49D867/49C813]-1-1 (axial orientation) resulted in an average energy decrease of 26 ft-lb after irradiation. This decrease results in an irradiated average upper-shelf energy of 126 ft-lb for the axially oriented specimens.
The average upper-shelf energy of the Surveillance Program Weld Material (Heat # 442011) Charpy specimens resulted in an average energy increase of 1 ft-lb after irradiation. Although physically WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 1-2 unreasonable, this increase results in an irradiated average upper-shelf energy of 70 ft-lb for the weld metal specimens.

The average upper-shelf energy of the HAZ material Charpy specimens resulted in an average energy decrease of 3 ft-lb after irradiation. This decrease results in an irradiated average upper-shelf energy of 125 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 U.S. NRC Regulatory Guide 1.99, Revision 2 [Re£ 1] for the Braidwood Unit 1 reactor vessel surveillance materials are presented in Table 5-10.
Based on the upper-shelf energy evaluation in Appendix D, all beltline and extended beltline materials contained in the Braidwood Unit 1 reactor vessel exhibit adequate upper-shelf energy levels for continued safe plant operation and are predicted to maintain an upper-shelf energy greater than 50 ft-lb through end-of-license extension (57 EFPY) as required by 10 CFR 50, Appendix G [Ref. 2].
The maximum calculated 57 EFPY (end-of-license extension) neutron fluence (E > 1.0 MeV) for the Braidwood Unit 1 reactor vessel beltline using the U.S. NRC Regulatory Guide 1.99, Revision 2 attenuation formula (i.e., Equation# 3 in the Guide) is as follows:

Westinghouse Non-Proprietary Class 3 2-1 2 INTRODUCTION This report presents the results of the examination of Capsule V, the fourth capsule removed and tested in the continuing surveillance program, which monitors the effects of neutron irradiation on the Exelon Generation (Exelon) Braidwood Unit 1 reactor pressure vessel materials under actual operating conditions. The surveillance program for the Braidwood Unit 1 reactor pressure vessel materials was designed and recommended by Westinghouse Electric Company, LLC. A detailed description of the surveillance program and the pre-irradiation mechanical properties of the reactor vessel materials are presented in WCAP-9807 [Ref. 3], "Commonwealth Edison Company Braidwood Station Unit No. 1 Reactor Vessel Radiation Surveillance Program." The surveillance program was originally planned to cover the 40-year design life of the reactor pressure vessel and was based on ASTM E185-73 [Ref. 4], "Standard Recommended Practice for Surveillance Tests for Nuclear Reactor Vessels." Capsule V was removed from the reactor after 17.69 EFPY of exposure and stored in the spent fuel_ pool. During Cycle 19, it was shipped to the Westinghouse Materials Center of Excellence 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 and post-irradiation data obtained from surveillance Capsule V removed from the Braidwood Unit 1 reactor vessel and discusses the analysis of the data. WCAP-18092-NP May2016 Revision 1

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 SA508 Class 3 (base material of the Braidwood Unit 1 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 (axial) to the major working direction of the forging. The RTNDT of a given materfar kiised to index thaf materiaffo a reference stress intensity factor curve (Krc curve) that appears in Appendix G to Section XI of the ASME Code [Ref. 5]. The Krc 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 Kic curve, allowable stress intensity factors can be obtained for this m11terial as a function of temperature. Then, allowable operating limits can be determined using these allowable stress intensity factors. RTNDr 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 Braidwood Unit 1 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 (Lill.TNDr) due to irradiation is added to the initial RTNDT, along with a margin (M) to cover uncertainties, to adjust the RTNDr (ART) for radiation embrittlement. This ART (initial RTNDT + M + Lill.TNDT) 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.

Westinghouse Non-Proprietary Class 3 4-1 4 DESCRIPTION OF PROGRAM Six surveillance capsules for monitoring the.effects of neutron exposure on the Braidwood Unit 1 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, as shown in Figure 4-1, between the core barrel and the vessel wall, at various azimuthal locations. The vertical center of the capsules is opposite the vertical center of the core. The capsules contain specimens made from the following:

Lower Shell Forging [49D867/49C813]-l-1 (tangential orientation)
Lower Shell Forging [49D867/49C813]-l-1 (axial orientation)
Weld metal fabricated with weld wire Heat Number 442011, Linde Type 80 flux, which is equivalent to the .heat number and Flux Type used in the actual fabrication of the intermediate shell to lower shell circumferential weld seam
Weld heat-affected zone (HAZ) material of Lower Shell Forging [49D867/49C813]-l-l Test material obtained from the lower shell forging (after thermal heat treatment and. forming of the forging) was taken at least one forging thickness from the quenched edges of the forging. All test specimens were machined from the Y4 thickness location of the forging after performing a simulated post-weld stress-relieving treatment on the test material. Weld test specimens were removed from the weld metal of a stress.:.relieved weldment joining Lower Shell Forging [49D867/49C813]-1-l and adjacent Intermediate Shell Forging [49D383/49C344]-l-1. All heat-affected zone specimens were obtained from the weld heat-affected zone of Lower Shell Forging [49D867/49C813]-1-1.

Charpy V-notch impact specimens from Lower Shell Forging [49D867/49C813]-1-1 were machined in the tangential orientation (longitudinal axis of the specimen parallel to the major working direction) and also in the axial orlentltlon- (longitudinal a.Xis of the specifilen perpendicular to the major working direction). *The cor~regi.on weld Charpy impact specimens were machined from the weldment such that the long dimension of each Ch.3.rpy 8pecimen 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 Forging [49D867/49C813]-J.,.1 were machined both in the tangential and axial orientation. Tensile specimens from the weld metal were oriented perpendicular to the welding direction. Compact tension test specimens (1/2T) from forging [49D867/49C813]-1-l were machined in both the tangential and axial 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 precracked according to ASTM E399 [Ref. 7]. All six capsules contain dosimeter wires of pure iron, copper, nickel, and aluminum-0.15 weight percent cobalt (cadmium-shielded and unshielded). Additionally, cadmium-shielded dosimeters of neptunium {237Np) and uranium (238U) were placed in the capsules to measure the integrated flux at specific neutron energy levels. WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 . 4-2 The capsules contain thermal monitors made from two low-melting-point eutectic alloys, which were sealed in Pyrex 1 tubes. These thermal monitors were located in three different positions in the capsule. These thermal monitors are 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: 2.5% Ag, 97 .5% Pb Melting Point: 579°F (304°C) 1.75% Ag, 0.75% Sn, 97.5% Pb Melting Point: 590°F (310°C) The chemical composition and the heat treatment of the various mechanical specimens in Capsule V are presented in Tables 4-1 and 4-2, respectively. The data in Tables 4-1 and 4-2 was obtained from the original surveillance program report, WCAP-9807 [Ref. 3], Appendix A. Capsule V was removed after 17 .69 EFPY of plant operation. This capsule contained Charpy V-notch specimens, tensile specimens, compact tension specimens, dosimeters, and thermal monitors. The arrangement of the various mechanical specimens, dosimeters and thermal monitors contained in Capsule V is shown in Figure 4-2. 1 Pyrex is a registered trademark of Corning Incorporated.

Westinghouse Non-Proprietary Class 3 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 at the Westinghouse Materials Center of Excellence Hot Cell Facility. Testing was performed in accordance with 10 CFR 50, Appendix H [Ref. 2] and ASTM Specification E185-82 [Re£ 8]. Capsule V was opened upon receipt at the hot cell laboratory. The specimens and spacer blocks were carefully removed, inspected for identification number, and checked against the master list in WCAP-9807 [Ref. 3]. All of the items were in their proper locations. Examination of the thermal monitors indicated that at least two of the three temperature monitors had melted. The third temperature monitor could not be properly examined due to the opacity of the Pyrex tube. Based on this examination, the maximum temperature to which the specimens were exposed was greater than 590°F (310°C). The Charpy impact tests were performed per ASTM Specification El85-82 [Ref. 8] and E23-12c [Ref. 9] on a Tinius-Olsen Model 74, 358J machine. The Charpy machine striker was instrumented with an lnstron 1 Impulse syst~m. Instrumented testing and calibration were performed to ASTM E2298-13a [Ref. 10]. The instrumented striker load signal data acquisition rate was 819 kHz with data acquired for 10 ms. From the load-time cm-Ve, the load of general yielding (Fgy), the maximum load (Fm) and the time to maximum load were 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 initiation/load at initiation of unstable crack propagation (Fbr). The termination load after the fast load drop is identified as the arrest load/load at. end of wistable crack propagation (Fa). Fgy, Fm, Fbr. and Fa were determined per the guidance in ASTM Standard E2298-13a [Re£ 10].

The pre-maximum load energy (Wm) was determined by integrating the load-time record to the maximum load point via the instrumented Charpy software. The pre-maximum load energy is approximately equivalent t~ the *~nergy reqttlre{i_ to icl.tiate a era.Ck: in the specinlen'. Therefore, the propagation energy for the c~k (Wp) is the -difference betWeen -the totai inipict energy CWt) and the pre-maximum ioad energy (Wm). Wt is compared to the absorbed energy measured from the dial energy (KV). Percent shear was determined from post-fracture photographs using the ratio-of-areas method in compliance with ASTM E23-12c [Ref. 9] and A370-14 [Ref. 11]. The lateral expansion was measured using a dial gage rig similar to that shown in the same ASTM Standards. Tens.ile tests were performed on a 250 kN Instron screw driven tensile machine (Model 5985) per ASTM E185-82 [Re£ 8]. Testing met ASTM Specifications E8/E8M-15a [Re£ 12] for room temperature or met ASTM Specification E21-09 [Ref. 13] for elevated temperatures. 1 Instron is a registered trademark of lnstron* Corporation. WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 5-2 The tensile specimens were, nominally, 4.230 inches long with a 1.000 inch gage length and 0.250 inch in diameter, per WCAP-9807 [Ref. 3]. Strain measurements were made using an extensometer, which was attached to the 1.00 inch gage section of the tensile specimen. The strain rate obtained met the requirements of ASTM E8/E8M-15a [Ref. 12] and ASTM E21-09 [Ref. 13]. Elevated test temperatures were obtained with a three-zone electric resistance split-tube Instron SF-16 furnace with an 11-inch hot zone. For the elevated tests, temperature was measured by two Type N thermocouples in contact with the gage section of the specimen per ASTM E21-09 [Ref. 13]. Tensile specimens were soaked at temperature (+/-5°F) for a minimum of 20 minutes before testing. All tests were conducted in air. The yield load, ultimate load, fracture load, uniform elongation, and elongation at fracture were determined directly from the load-extension curve. The yield strength (0.2% offset method), ultimate tensile strength and fracture strength were calculated using the original cross-sectional area. Yield point elongation (YPE) was calculated as the difference in strain between the upper yield strength and the onset of uniform strain hardening using the methodology described inASTM E8/E8M-15a . [Ref. 12]. The final diameter and final gage length were determined from post-fracture photographs. This final diameter measurement was used to calculate the fracture stress (fracture true stress) and the percent reduction in area. The final and original gage lengths were used to calculate total elongation after fracture. 5.2 CHARPYV-NOTCH IMPACT TEST RESULTS The results of the Charpy V-notch impact tests performed on the various materials contained in Capsule V, which received a fluence of 3.71 x 1019 Dlcm2 (E > 1.0 MeV) in 17.69 EFPY of operation, are presented in Table 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-9807 [Ref. 3], WCAP-12685 [Ref. 14], WCAP-14241 [Ref. 15], and WCAP-15316, Revision 1 [Ref. 16].. The previous capsules, along with the original program unirradiated material input data, were updated using CVGRAPH, Version 6.02. The transition temperature increases and decreases in upper-shelf energies for the Capsule V materials are summarized in Table 5-9 and led to the following results:

Irradiation of the reactor vessel Lower Shell Forging [49D867/49C813]-1-1 Charpy specimens, oriented with the longittidinal axis of the specimen parallel to the major working direction (tangential orientation), resulted in an irradiated 30 ft-lb transition temperature of -24.6°F and an irradiated 50 ft-lb transition temperature of 6. 7°F. This results in a 30 ft-lb transition temperature increase of 51.3°F and a 50 ft-lb transition temperature increase of 47.8°F for the tangentially oriented specimens.
Irradiation of the reactor vessel Lower Shell Forging [49D867/49C813]-1-1 Charpy specimens, oriented with the longitudinal axis of the specimen perpendicular to the major working direction (axial orientation), resulted in an irradiated 30 ft-lb transition temperature of -8.0°F and an irradiated 50 ft-lb transition temperature of 26.9°F. This results in a 30 ft-lb transition temperature increase of 39.7°F and a 50 ft-lb transition temperature increase of 42.7°F for the axially oriented specimens.

WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 5-3

Irradiation of the Surveillance Program Weld Material (Heat # 442011) Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of 36.7°F and an irradiated 50 ft-lb transition temperature of 104.3°F. This results in a 30 ft-lb transition temperature increase of 62.8°F and a 50 ft-lb transition temperature increase of 79 .1°F.
Irradiation of the HAZ material Charpy specimens resulted in an irradiated 30 ft-lb transition temperature of -66.0°F and an irradiated 50 ft-lb transition temperature of -16.6°F. This decrease results in a 30 ft-lb transition temperature increase of 171.0°F and a 50 ft-lb transition temperature increase of 119.1°F.
The irradiated upper-shelf energy of Lower Shell Forging [49D867/49C813]-l-1 (tangential orientation) resulted in an average energy decrease of 3 ft-lb after irradiation. This decrease results in an irradiated average upper-shelf energy of 163 ft-lb for the tangentially oriented specimens.
The average upper-shelf energy of Lower Shell Forging [49D867/49C813]-1-1 (axial orientation) resulted in an average energy decrease of 26 ft-lb after irradiation. This decrease results in an irradiated average upper-shelf energy of 126 ft-lb for the axially oriented specimens.
The average- upper--shelf energy of the Surveillance Program Weld Material (Heat # 442011) Charpy specimens resulted in an average energy increase of 1 ft-lb after irradiation. Although physically unreasonable, this increase results in an irradiated average upper-shelf energy of 70 ft-lb for the weld metal specimens.
TJ:te ayerage upper-shelf energy of the HAZ Material Charpy specimens resulted in an average energy decrease of 3 ft-lb after irradiation. This decrease results in an irradiated average upper-shelf energy of 125 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 U.S. NRC Regulatory Guide 1.99, Revision 2 [Ref. 1] for the Braidwood Unit 1 reactor vess~l slirveillance materials are presented in Table 5-10.

The fracture appearances of each irradiated Charpy specimen from the various materials are 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. With consideration of the surveillance data, all beltline and extended beltline materials exhibit adequate upper-shelf energy levels for continued safe plant operation and are predicted to maintain an upper-shelf energy greater than 50 ft-lb through end-of-license extension (57 EFPY), as required by 10 CFR 50, Appendix G [Ref. 2]. This evaluation is contained in Appendix D. WCAP-18092-NP May2016 Revision 1

The results of the tensile tests performed on the Lower Shell Forging [49D867/49C813]-1-1 (tangential orientation) indicated that irradiation to 3.71 x 1019 n/cm2 (E > 1.0 MeV) caused increases in the 0.2% 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 Forging [49D867/49C813]-l-1 (axial orientation) indicated that irradiation to 3.71 x 1019 n/cm2 (E > 1.0 MeV) caused increases in the 0.2% 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 Program Weld Material (Heat # 442011) indicated that irradiation to 3.71 x 10 19 n/cm2 (E > 1.0 MeV) caused increases in the 0.2% 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 Forging [49D867/49C813]-1-1 (tangential orientation) material are shown in Figure 5-20, the fractured tensile specimens for the Lower Shell Forging [49D867/49C813]-1-1 (axial orientation) are shown in Figure 5-21, and the fracture tensile specimens for the Surveillance Program Weld Material (Heat# 442011) 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 Materials Center of Excellence Hot Cell Facility.

Westinghouse Non-Proprietary Class 3 6-1 6 RADIATION ANALYSIS AND NEUTRON DOSIMETRY

6.1 INTRODUCTION

This section describes a discrete ordinates (S 0 ) transport analysis performed for the Braidwood Unit 1 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 14th plant operating cycle, is provided. In addition, the sensor sets from the previously withdrawn and analyzed capsules (U, X, and W) were re-analyzed and are presented. 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 form the basis for 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. However, in recent years, 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 E853-13, "Standard Practice for Analysis and Interpretation of Light-Water Reactor Surveillance Results," [Ref. 17] recommends reporting displacements per iron atom (dpa) along with tluence (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 E693-94, "Standard Practice for Characterizing Neutron Exposures in Iron and Low Alloy Steels in Terms of Displacements per Atom" [Ref. 18]. 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 U.S. NRC Regulatory Guide 1.99, "Radiation Embrittlement of Reactor Vessel Materials" [Ref. l]. All of the calculations and dosimetry evaluations described in this section and in Appendix A were based on nuclear cross-section data derived from ENDF/B-VI and used the latest available calculational tools. Furthermore, the neutron transport and dosimetry evaluation methodologies follow the guidance of U.S. NRC Regulatory Guide 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence" [Ref. 19]. 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" [Ref. 20]. WCAP-18092-NP May 2016 Revision 1

Westinghouse Non-Proprietary Class 3 6-2 6.2 DISCRETE ORDINATES ANALYSIS The arrangement of the surveillance capsules in the Braidwood Unit 1 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 58.5°, 61.0°,

121.5°, 238.5°, 241.0°, and 301.5°, as shown in Figure 4-1. These full-core positions correspond to the octant symmetric locations shown in Figures 6-2 and 6-3: 29.0° from the core cardinal axes (for the 61.0° and 241.0° capsules) and 31.5° from the core cardinal axes (for the 58.5°, 121.5°, 238.5°, and 301.5° capsules). The stainless steel specimen containers are 1.63-inch by 1.25-inch and are approximately 60 inches in height. The containers are positioned axially such that the test specimens are centered on the core midplane, thus spanning the approximate 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 significant effect on both the spatial distribution of neutron fluence rate and the neutron spectrum in the vicinity of the capsules. However, the capsules are far enough apart that they do not interfere with one another. 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 Braidwood Unit 1 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: cp(r, 0, z) = cp(r, 0)

cp~~r;) (Equation. 6-1) where cj>(r,9,z) is the synthesized three-dimensional neutron flux distribution, cj>(r,9) is the transport solution in r,9 geometry, cj>(r,z) is the two-dimensional solution for a cylindrical reactor model using the actual axial core power distribution, and cj>(r) is the one-dimensional solution for a cylindrical reactor model using the same source per unit height as that used in the r,9 two-dimensional calculation. This synthesis procedure was carried out for each operating cycle at Braidwood Unit I.

For the Braidwood Unit I transport calculations, the r,0 models depicted in Figures 6-1 through 6-3 were utilized because, 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 octants not containing surveillance capsules and octants with surveillance capsules at 29° and 31.5°), 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, water, and miscellaneous core structures, such as fuel assembly grids, guide tubes, etc. The geometric mesh description of the r,9 reactor model in Figure 6-1 consisted of 257 radial by 131 azimuthal intervals. The geometric mesh description of the r,0 reactor models in Figure 6-2 and Figure 6-3 consisted of 255 radial WCAP-18092-NP May 2016 Revision 1

Westinghouse Non-Proprietary Class 3 6-3 by 143 azimuthal intervals. Mesh sizes were chosen to ensure that proper convergence of the inner iterations was achieved on a pointwise basis. The pointwise inner iteration flux convergence criterion utilized in the r,9 calculations was set at a value of 0.001. The r,z model used for the Braidwood Unit 1 calculations, shown in Figure 6-4, extends radially from the centerline of the reactor core out to the primary biological shield and over an axial span from an elevation below the lower core support to several feet above the upper core plate. As in the case of the r,9 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 r,z geometric mesh description of these reactor models consisted of 153 radial by 216 axial intervals. As in the case of the r,9 calculations, mesh sizes were chosen to ensure that proper convergence of the inner iterations was achieved on a pointwise basis. The pointwise inner iteration flux convergence criterion utilized in the r,z 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 r,z 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 for each of the first 19 fuel cycles at Braidwood Unit 1 included cycle-dependent fuel assembly initial enrichments, burnups, and axial power distributions (note that Cycles 1 through 18 have been completed; Cycle 19 is based on the expected core design for this cycle and an assumed cycle length of 1.5 EFPY). 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 the fuel cycle-averaged neutron fluence rate, 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 235U 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 [Ref. 23] and the BUGLE-96 cross-section library [Ref. 22]. The BUGLE-96 library provides a coupled 47-neutron, 20-gamma-group cross-section data set produced specifically for light-water reactor (LWR) applications. In these analyses, anisotropic scattering was treated with a P5 Legendre expansion, and angular discretization was modeled with an S16 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 Table 6-1 through Table 6-12. In Table 6-1 and Table 6-2, the calculated exposure rates and integral exposures expressed in terms of fast neutron fluence rate (E > 1.0 MeV) and fast neutron fluence (E > 1.0 MeV), respectively, are given at the radial and azimuthal center of the surveillance capsule positions (i.e., for the 29 .0° and 31.5° dual capsule holder locations and 31.5° single capsule holder location). In Table 6-3 and Table 6-4, the calculated WCAP-18092-NP May 2016 Revision 1

Westinghouse Non-Proprietary Class 3 6-4 exposure rates and integral exposures expressed in terms of iron atom displacement rate (dpa/s) and iron atom displacements (dpa), respectively, are given at the radial and azimuthal center of the surveillance capsule positions (i.e., for the 29.0° and 31.5° dual capsule holder locations and 31.5° single capsule holder location). All surveillance capsules have been removed from Braidwood Unit l; therefore, results are not presented beyond Cycle 14 (as there are no capsules receiving fluence). These results, representative of the average axial exposure of the material specimens, establish the calculated exposure of the surveillance capsules. Similar information in terms of calculated fast neutron fluence rate (E > 1.0 MeV), fast neutron fluence (E > 1.0 MeV), dpa/s, and dpa, are provided in Table 6-5 through Table 6-8, for the reactor vessel inner radius at four azimuthal locations, as well as for the maximum exposure observed within the octant. The vessel data given in Table 6-5 through Table 6-8 were taken at the clad/base metal interface and represent maximum calculated exposure levels on the vessel. From the data provided in Table 6-6, it is noted that the peak clad/base metal interface vessel fluence (E > 1.0 MeV) at the end of the 18th fuel cycle (i.e., after 23.33 EFPY of plant operation) was 1.26E+19 n/cm2

Table 6-6 and Table 6-8 include both plant- and fuel-cycle-specific calculated neutron exposures at the end of the 18th fuel cycle, at the end of projected Cycle 19, and further projections to 60 EFPY. The calculations account for the uprate from 3411 MWt to 3586.6 MWt that occurred during Cycle 9, and incorporate an uprate from 3586.6 MWt to 3658 MWt that occurred during Cycle 18. The projections are based on the assumption that the core power distributions and associated plant operating characteristics from the design of Cycle 19 are representative of future plant operation. The future projections are based on the uprated reactor power level of 3658 MWt.

The calculated fast neutron exposures for all six surveillance capsules withdrawn from the Braidwood Unit 1 reactor are provided in Table 6-9. These neutron exposure levels are based on the plant- and fuel cycle-specific neutron transport calculations performed for the Braidwood Unit 1 reactor. From the data provided in Table 6-9, Capsule V received a fast neutron fluence (E > 1.0 MeV) of 3.71E+19 n/cm2 after exposure through the end of the 14th fuel cycle (i.e., after 17 .69 EFPY). Updated lead factors for the Braidwood Unit 1 surveillance capsules are provided in Table 6-10. The capsule lead factor is defined as the ratio of the calculated fast neutron fluence (E > 1.0 MeV) at the geometric radial and azimuthal center of the surveillance capsule to the corresponding maximum calculated fast neutron fluence at the pressure vessel clad/base metal interface. In Table 6-10, the lead factors for capsules that have been withdrawn from the reactor (Capsules U, X, W, V, Y, and Z) were based on the calculated fluence values for the irradiation period corresponding to the time of withdrawal for the individual capsules. Table 6-11 presents the maximum fast neutron fluences (E > 1.0 MeV) and Table 6-12 presents the maximum iron atom displacements for pressure vessel materials. 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 WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 6-5 serve to validate the calculated results, only the direct comparison of measured-to-calculated results for the most recent surveillance capsule analyzed is provided in this section. 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, which was withdrawn from Braidwood Unit 1 at the end of the 14th fuel cycle, is summarized below. Reaction Rate (rps/atom) Reaction MIC Measured (M) Calculated (C) Cu-63(n,a)Co-60 4.02E-17 3.66E-17 1.10 Fe-54(n,p )Mn-54 3.81E-15 3.97E-15 0.96 U-23 8(Cd)(n,f)Cs-13 7 2.37E-14 2.12E-14 1.12 Np-237(Cd)(n,f)Cs-l 37 l.99E-13 2.06E-13 0.97 Average 1.04

                % standard deviation                                               8.1 The measured-to-calculated (M/C) reaction rate ratios for the Capsule V threshold reactions range from 0.96 to 1.12, and the average M/C ratio is 1.04 +/- 8.1% (lcr). This direct comparison falls within the

+/- 20% criterion specified in U.S . NRC Regulatory Guide 1.190. This comparison validates the current analytical results described in Section 6.2; therefore, the calculations are deemed applicable for Braidwood Unit 1. 6.4 CALCULATIONAL UNCERTAINTIES The uncertainty associated with the calculated neutron exposure of the Braidwood Unit 1 surveillance capsule and reactor pressure vessel is based on the recommended approach provided in U.S. NRC 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.

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 Braidwood Unit 1 surveillance program.

WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 6-6 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 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 Braidwood Unit 1 analysis was established from results of these three phases of the methods qualification. The fourth phase of the uncertainty assessment (comparisons with Braidwood Unit 1 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 described in Section 6.2. As such, the validation of the Braidwood Unit 1 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 21. Description Capsule and Vessel IR PCA Comparisons 3% H. B. Robinson Comparisons 3% Analytical Sensitivity Studies 11% Additional Uncertainty for Factors not Explicitly 5% Net Calculational Uncertainty 13% The net calculational uncertainty was determined by combining the individual components in quadrature. Therefore, the resultant uncertainty was treated as 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 Braidwood Unit 1. WCAP-18092-NP May2016 Revision 1

No testing or analysis has been performed on these capsules. (b) The capsule lead factors are slightly different from those determined in Reference 24 (for example, 4.01 vs 4.02 for Capsule U). These differences could be attributed to the change from RadTrack Version 1.1.1 to 2.0 or some input data may now carry more significant figures. RadTrack is a graphical user interface (GUI) that encompasses Westinghouse's currently-approved fluence calculation and dosimetry analysis methodology. WCAP-18092-NP May2016 Revision 1

(b) EFPY from plant startup. (c) Updated in Capsule V dosimetry analysis; see Table 6-9. (d) Capsule Z was removed and placed in the spent fuel pool. Capsule Z could be reinserted into the Braidwood Uajt 1 :i;eaj:of _V~!!el to provide meairingful metallurgical data for 80 years of plant operation. If Capsule Z were reinserted ~to either v~can'tji.5~-dwtl-capSui~-lo~~tlon, it would receive the projected 80-year (76 EFPY)_ fluence_of 4.36_x 1019 n/~m2 _ji;t 6.8 EFPY. Capsu1e Z would exceed two times the projected 80-year (76 EFPY) fluence of 8.72 x 1019 n/cm2 in 25.7 EFPY. However, since the Braidwood Unit 1 surveillance capsule positions have relatively high fast flux, reinsertion of this capsule can be revisited at a later date if an additional 20-year license extension is sought (e) Capsule Y should remain in the spent fuel pool. Potential reinsertion and/or testing of this capsule can be revisited at a later date if additional metallurgical data are needed for Braidwood Unit 1. (f) The neutron fluence exposure of Capsule V is greater than once, but less than twice the peak vessel fluence (3.22 x 1019 n/cm.2) at 57 EFPY; therefore, Capsule V satisfies the requirements for a license renewal capsule for 60 years of plant operation.

Westinghouse Non-Proprietary Class 3 A-1 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 and ex-vessel neutron dosimetry (EVND) withdrawn and analyzed to date at Braidwood Unit 1 are described herein. The sensor sets have been analyzed in accordance with the current dosimetry evaluation methodology described in U.S. NRC 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 U.S. NRC 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 four surveillance capsules analyzed to date as part of the Braidwood Unit 1 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 Azimuthal Withdrawal Time Irradiation Time (EFPY) Location Surveillance Capsule U 58.5° End of Cycle 1 1.16 Surveillance Capsule X 238.5° End of Cycle 4 4.30 Surveillance Capsule W 121.5° End of Cycle 7 7.79 Surveillance Capsule V 61° End of Cycle 14 17.69 WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 A-2 The passive neutron sensors included in the evaluations of surveillance Capsules U, X, W, and V are summarized as follows: Sensor Material Reaction of Interest Capsule u Capsule x Capsule w CapsuleV Copper 63 Cu(n,a.)6°Co x x x x Iron S4Fe(n,p)S4Mn x x x x Nickel 5 8Ni(n,p) 58Co x x x Note (a) Uranium-238(Cd) 238 U(n,t)FP x x x x Neptunium- 237 Np(n,t)FP x x x x 237(Cd) Cobalt- s9Co(n,y)60Co x x x x Aluminum.Cb) Notes: (a) The nickel monitors were not considered for Capsule V. The reaction product has a relatively short half-life (70.82 days, see Table A-1), and decayed beyond utility in the intervening period between when Capsule V was pulled (March 2009) and when it was counted (September 2015). (b) The cobalt-aluminum monitors for this plant include both bare and cadmium-covered sensors. This section also includes the results of the evaluations of the four midplane EVND capsules and two off-midplane EVND capsules analyzed to date. The EVND was irradiated during Cycle l4, then removed and analy2:ed. The capsule designation, aznnuthal location outside the vessel, and axial location were as follows: Capsule Azilnuthal Location Axial Location from Cardinal Axis EVND Capsule A 050 Core Midplane EVND Capsule B 14.5° Core Midplane EVND Capsule C 29.5° Core Midplane EVND Capsule E 445° Core Midplane EVND Capsule D 44.5° Top of Active Core EVND Capsule F 445° Bottom of Active Core WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 A-3 The passive neutron sensors included in the evaluations of EVND Capsules A, B, C, D, E, and F are summarized as follows: Sensor Reaction Of Capsule Capsule Capsule Capsule Capsule Capsule Material Interest A B c D E F Copper 63 Cu(n,a) 6°Co x x x x x x Titanium 46Ti(n,p)46Sc x x x x x x Iron 54Fe(n,p)54Mn x x x x x x Nickel 58Ni(n,p)58 Co x x x x x x Niobium 93Nb(n,n.')93~ x x x x x x Cobalt- 59Co(n,y)6°Co x x x x x x Aluminum(a) Note: (a) The cobalt-aluminum monitors for this plant include both bare and cadmium-covered sensors. Pertinent physical and nuclear characteristics of the passive neutron sensors analyzed 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 fluence rate 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 fluence rate has on the target material over the course of the irradiation. period. An accurate assessment of the average neutron fluence rate 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,
the physical characteristics of each monitor,
the operating history of the reactor,
the energy response of each monitor, and
the neutron energy spectrum at the monitor location..

Results from the radiometric counting of the neutron sensors from Capsules U, X, and W are documented in References A-2, A-3, and A-4, respectively. The radiometric counting of the sensors from Capsule V was carried out by Pace Analytical Services, Inc. The radiometric counting followed established ASTM procedures. Results from the radiometric counting of EVND irradiated during Cycle 14 are documented in Reference A-5. The irradiation history of the reactor over the irradiation periods experienced by Capsules U, X, Wand V was based on the monthly thermal power generation of Braidwood Unit 1 from initial reactor criticality through the end of the dosimetry evaluation period. Analysis of the EVND used Cycle 14 monthly thermal generation data. For the sensor sets utilized in the surveillance capsules and EVND, 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 WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 A-4 exposure evaluations. The irradiation history applicable to surveillance Capsules U, X, W, and V and EVND irradiated during Cycle 14 is given in TableA-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 =------------ N0FYL: pj Cj[l-e-).ti][e-M11,i] 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/g). N0 = 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 (MW). Pref Maximum or reference power level of the reactor (MW). c; Calculated ratio of cl> (E > 1.0 MeV) during irradiation period j to the time weighted average cl> (E > 1.0 MeV) over the entire irradiation period. A. Decay constant of the product isotope (I/sec). tj Length of irradiation periodj (sec). 1cl,j = Decay time following irradiation period j (sec). 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]l[Pred 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 fluence rate level induced by changes in core spatial power distributions from fuel cycle to fuel cycle. For a single-cycle WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 A-5 irradiation, Cj is normally taken to be 1.0. However, for multiple-cycle irradiations, the additional q term should be employed. The impact of changing tluence rate 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 tluence rates and the computed values for Cj are listed in Tables A-3 and A-4, respectively, for Capsules U, X, W, and V. These tluence rates represent the capsule- and cycle-dependent results at the radial and azimuthal center of the respective capsules at core 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 cadmium-covered measurements to account for the presence of 235 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 238U and 237Np sensor reaction rates to account for gamma ray-induced fission reactions that occurred over the course of the surveillance capsule irradiations. The correction factors corresponding to the Braidwood Unit 1 fission sensor reaction rates are summarized as follows: Correction Capsule U CapsuleX CapsuleW CapsuleV 235 U Impurity/Pu Build-in 0.869 0.839 0.810 0.752 23sU(y,f) 0.966 0.967 0.970 0.968 Net 238U Correction 0.839 0.811 0.786 0.728 238Np(y,f) Correction 0.990 0.990 0.991 0.991 The correction factors for surveillance Capsules U, X, W, and V were applied in a multiplicative fashion to the decay-corrected cadmium-covered uranium and neptunium fission sensor reaction rates. Results of the sensor reaction rate determinations for surveillance Capsules U, X, W, and V are given in Tables A-5 through A-8. In Tables A-5 through A-8, the measured specific activities, decay-corrected saturated specific activities, and computed reaction rates for each sensor are listed. The cadmium-covered fission sensor reaction rates are listed both with and without the applied corrections for 235U impurities, plutonium build-in, and gamma ray-induced fission effects. Results of the sensor reaction rate determinations for midplane EVND Capsules A, B, C, and E are given in Tables A-9 through A-12. Results of the sensor reaction rate determinations for off-midplane EVND Capsules D and F are given in TaJ>les A-13 and A-14, respectively. In Tables A-9 through A-14, the measured specific activities, decay-corrected saturated specific activities, and computed reaction rates for each sensor are listed. 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 WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 A-6 associated uncertainties. Best-estimates for key exposure parameters such as fluence rate (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 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, Ri +/-oR; = :LCuig +/-oa;,)(cpg +/-ocp.) g relates a set of measured reaction rates, Rt, to a single neutron spectrum, ~g. through the multigroup dosimeter reaction cross-sections, O"ig, each with an uncertainty o. 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 Braidwood Unit 1 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 paranieters [fast neutron fluence rate (E > 1.0 MeV) and iron atom displacement rate] along with associated uncertainties for the four in-vessel capsules and six ex-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 Braidwood UniU application, the. calculated neutron spectrum was obtained from the results of plant-specific neutron !Fa~pt:>rt_ c~l~ul~tion~ described in Section 6.2 of thls report. The sensor reaction rates were derived from ~e nieasure<;i specific activities usfug 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 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 AS1M Standard E944, "Standard Guide for Application of Neutron Spectrum Adjustment Methods in Reactor Surveillance" [Ref. A-8]. The following provides a summary of the uncertainties associated with the least-squares evaluation of the Braidwood Unit 1 surveillance capsule and EVND sensor sets. WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 . A-7 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 ensured 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: Reaction Uncertainty 63 Cu(n,a.)6°co 5% 46 Ti(n,p )46 Sc 5% s4Fe(n,p)s4Mn 5% 58Ni(n,p)5 8Co 5% 93Nb(n,n')93°Nb 5% 238U(n,t)FP 10% 237Np(n,t)FP 10% 59Co(n,y)6°Co 5% These uncertainties are given at the lcr 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 multigroup structure for use in least-squares adjustment applications. These cross-sections were compiled from recent cross-section evaluations, and they have been tested for 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 Braidwood Unit 1 surveillance program, the following uncertainties in the fission spectrum averaged cross-sections are provided in the SNLRML documentation package.

Calculated Neutron Spectrum The neutron spectra inputs to the least-squares adjustment procedure were obtained directly from the results of plant-specific transport calculations for each surveillance capsule and EVND 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: 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: Where: (g-g')2 H=-- 2y2 WCAP-18092-NP May2016 Revision 1

Westinghouse Non-Proprietary Class 3 A-9 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 (9 specifies the strength of the latter term). The value of C5 is 1.0 when g = g', and is 0.0 otherwise. The set of parameters defining the input covariance matrix for the Braidwood Unit 1 calculated spectra was as follows: Fluence Rate Normalization Uncertainty (Rn) 15% Fluence Rate 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 (9) (E > 0.0055 MeV) 0.9 (0.68 eV < E < 0.0055 MeV) 0.5 (E < 0.68 eV) 0.5 Fluence Rate 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 Braidwood Unit 1 surveillance capsules withdrawn to date are provided in Tables A-15, A-16, A-17, andA-18 for surveillance Capsules U, X, W, and V, respectively. Results of the least-squares evaluations of the EVND midplane capsules withdrawn to date are provided in 1'.ables A-19, A-20, A-21, and A-22 for EVND Capsules A, B, C, and E, respectively. Results of the least-squares evaluations of the EVND off-midplane capsules withdrawn to date are provided in Tables A-23 and A-24 for EVND Capsules D and F, respectively. In these tables, measured, calculated, and best-estimate values for sensor reaction rates are given for each capsule. Also provided in these tabulations are ratios of the measured reaction rates to both the calculated and least-squares adjusted reaction rates. These ratios of MIC 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. Additionally, comparisons of the calculated and best-estimate values of neutron fluence rate (E > 1.0 MeV) and iron atom displacement rate are tabulated along with the BE/C ratios observed for each of the capsules. Note that for surveillance Capsule V, nickel foils were omitted due to their lack of meaningful information. The reaction product has a relatively short half-life (70.82 days, see Table A-1 ), and decayed beyond utility in the intervening period between when Capsule V was pulled (March 2009) and when it was counted (September 2015). The data comparisons provided in Tables A-15 through A-22 show that the adjustIDents to the calculated spectra are relatively small and within the assigned uncertainties for the calculated spectra, measured sensor reaction rates, and dosimetry reaction cross-sections. Furthermore, these results indicate that the WCAP-18092-NP May2016 Revision 1

                                                                                                              - _J

Westinghouse Non-Proprietary Class 3 A-10 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, the calculational uncertainty is specified as 13% at the lcr level. Further comparisons of the measurement results with calculations are given in Tables A-25 through A-27 for in-vessel surveillance capsules, EVND midplane capsules, and EVND o:ff-midplane capsules. In these tables, 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 spectr~. Calculations of fast neutron exposure rates in terms of fast neutron fluence rate (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 in Tables A-28 and A-29 for in-vessel surveillance capsules and EVND midplane capsules, respectively. These comparisons yield consistent and similar results with all measurement-to-calculation comparisons falling within the 20% limits specified as the acceptance criteria in U.S. NRC Regulatory Guide 1.190 [Ref. A-l]. The measurement-to-calculation comparisons based on individual sensor reactions without recourse to the least-squares adjustment procedure are summarized in Table A-30. A similar comparison for exposure rates expressed in terms of fast neutron fluence rate (E > 1.0 MeV) and iron atom displacement rate is summarized in Table A-31. These data comparisons show similar and consistent results with the linear average MIC ratio of 0.99 in excellent agreement with the resultant least-squares BE/C ratios of 0.97 and 0.99 for fast neutron fluence rate (E > 1.0 MeV) and iron atom displacement rate, respectively. The comparisons demonstrate that the calculated results are validated within the context of the assigned 13% (lcr) uncertainty. Based on these comparisons, it is concluded that the calculated fast neutron exposures provided in Section 6.2 of this report-- are - validated for -lise in the assessment of the condition of the materials comprising the beltline region of the Braidwood Unit 1 reactor pressure vessel.

Westinghouse Non-Proprietary Class 3 C-1 APPENDIXC CHARPY V-NOTCH PLOTS FOR EACH CAPSULE USING SYMMETRIC HYPERBOLIC TANGENT CURVE-FITTING l\'IETHOD C.1 METHODOLOGY 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 6.02. The definition for USE is given in ASTM E185-82 [Ref. C-1], 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."

Westinghouse reports the average of all Charpy data (2: 95% shear) as the USE, excluding any values that are deemed outliers using engineering judgment. Hence, the Capsule V USE values reported in Table C-1 were deterinined 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-1 for the uni.rfadiated material, as well as Capsules U, X, and W, were also determined by applying the methodology described above to the Charpy impact data reported in WCAP-9807 [Ref. C-2], WCAP-12685 [Ref. C-3], WCAP-14241 [Ref. C-4], and WCAP-15316, Revision 1 [Ref. C-5]. The USE values reported in Table C-1 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 1.0 mil in order to be consistent with the previous capsule analysis [Ref. C-5].

Westinghouse Non-Proprietary Class 3 D-1 APPENDIXD BRAIDWOOD UNIT 1 UPPER-SHELF ENERGY EVALUATION D.1 EVALUATION Per U.S. NRC Regulatory Guide 1.99, Revision 2 [Ref. D-1], 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 D-1 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 USE may be obtained by plotting the reduced plant surveillance data on Figure 2 of the Guide (Figure D-1 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 end-of-license extension (57 effective full-power years [EFPY]) USE of the vessel materials can be predicted using the corresponding quarter-thickness (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 U.S. NRC Regulatory Guide 1.99, Revision 2 [Re£ D-1]. The Braidwood Unit I reactor vessel beltline region thickness is 8.5 inches per Reference D-3. Calculation of the 1/4T vessel fluence values at 57 EFPY for the beltline and extended beltline materials is shown in Table D-1. The following pages present the Braidwood Unit 1 USE evaluation. Figure D-1, as indicated above, is used in making predictions in accordance with U.S. NRC Regulatory Guide 1.99, Revision 2 [Ref. D-1 ]. Table D-2 provides the predicted USE values for 57 EFPY (end-of-license extension). WCAP-18092-NP May2016 Revision 1

(b) Consistent with the time-limited aging analysis (TLAA) evaluation as documented in Reference D-3, the maximum fluence values for the extended beltline materials at 57 EFPY were less than the minimum fluence value displayed on Figure 2 of U.S. NRC Regulatory Guide 1.99, Revision 2. The minimum fluence value (2 x 1017 n/cm2) displayed on Figure 2 of U.S. NRC Regulatory Guide 1.99, Revision 2 was conservatively used to determine the projected USE decrease; see Table D-2.

In calculating Position 1.2 percent USE decreases, the base metal and weld Cu weight percentages were conservatively rounded up to the nearest line in U.S. NRC Regulatory Guide l.99, Revision 2, Figure 2. (b) Calculated using surveillance capsule measured percent decrease in USE from Table 5-10 and U.S. NRC Regulatory Guide 1.99, Revision 2, Position 2.2; see Figure D-1. (c) The minimum fluence value (2 x 10 17 n/cm2) displayed on Figure 2 of U.S . NRC Regulatory Guide l.99, Revision 2 was conservatively used to determine the projected USE decrease.
