Conclusions and Recommendations Because the representative plate material is the same heat number as the target plate in the Cooper vessel, and because there are two irradiated data sets for this plate that fall within the 1-sigma scatter band, the ISP surveillance data in Appendix A-2 should be used to determine the projected ART value for the target vessel plate. Recommended guidelines for use of ISP surveillance data are provided in Section 3 of this Data Source Book.

Page 5 of45 An archival plate heat from the Cooper vessel, Plate Heat C2331-2, was included in the Supplemental Surveillance Program (SSP), and irradiated data from SSP Capsules D, G, E, I, A, and Bare provided in Appendix A-19. The credible surveillance data should be considered when a revised ART is calculated for vessel heat C233 l-2.

Conclusions and Recommendations I

Because the representative weld material is not the same heat number as the target weld in the Cooper vessel, the utility should use the chemistry factor from the Regulatory Guide 1.99, Rev. 2 tables to determine the projected ART value for the target vessel weld. Cooper surveillance weld heat 20291 is not in the Cooper vessel beltline. Recommended guidelines for evaluation of ISP surveillance data are provided in Section 3 of this Data Source Book.

The CVN test data for each set taken from the references noted above are presented in Tables A-2-7 through A-2-9. The BWRVIP ISP uses the hyperbolic tangent (tanh) function as a statistical curve-fit tool to model the transition temperature toughness data. Tanh curve plots for each data set have been generated using CVGRAPH, Version 5 [A-2-3] and the plots are provided in Figures A-2-1 through A-2-3.

Best Estimate Chemistry Table A-2-2 details the best estimate average chemistry values for plate heat C2307-2 surveillance material. Chemical compositions are presented in weight percent. If there are multiple measurements on a single specimen, those are first averaged to yield a single value for that specimen, and then the different specimens are averaged to determine the heat best estimate.

Page 7 of45 The radiation induced transition temperature shifts for heat C2307-2 are shown in Table A-2-3.

The T30 [30 ft-lb Transition Temperature], T50 (50 ft-lb Transition Temperature], and T35mu

[35 mil Lateral Expansion Temperature] have been determined for each Charpy data set, and each irradiated set is compared to the baseline (unirradiated) index temperatures. The change in Upper Shelf Energy (USE) is also shown. The unirradiated and irradiated values are taken from the CVGRAPH fits presented at the back of this sub-appendix (only CVN energy fits are presented).

Comparison of Actual vs. Predicted Embrittlement A predicted shift in the 30 ft-lb transition temperature (~T30) is calculated for each irradiated data set using the Reg. Guide 1.99, Rev. 2, Regulatory Position 1.1 method. Table A-2-4 compares the predicted shift with the measured ~T30 (°F) taken from Table A-2-3.

Comparison of Actual vs. Predicted Decrease in USE Table A-2-5 compares the actual percent decrease in upper shelf energy (USE) to the predicted decrease. The predicted decrease is estimated from USNRC Regulatory Guide 1.99, Rev. 2, Figure 2; the measured percent decrease is calculated from the values presented in Table A-2-3.

Credibility of Surveillance Data The credibility of the surveillance data is determined according to the guidance of Regulatory Guide 1.99, Rev. 2 and 10 CFR 50.61, as supplemented by the NRC staff [A-2-6]. The following evaluation is based on the available surveillance data for irradiated plate heat C2307-2. The applicability of this evaluation to a particular BWR plant must be confirmed on a plant-by-plant basis to verify there are no plant-specific exceptions to the following evaluation.

Page 10 of 45 Per Regulatory Guide 1.99, Revision 2 and 10 CFR 50.61, there are 5 criteria for the credibility assessment.

Criterion 1: Materials in the capsules should be those judged most likely to be controlling with regard to radiation embrittlement.

In order to satisfy this criterion, the representative surveillance material heat number must match the material in the vessel.

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 upper shelf energy unambiguously.

Plots of Charpy energy versus temperature for the unirradiated and irradiated condition are presented in this sub-appendix. Based on engineering judgment, the scatter in these plots is small enough to permit the determination of the 30 ft-lb temperature and the upper shelf energy. Hence, this criterion is met.

Criterion 3: When there are two or more sets of surveillance data from one reactor, the scatter of ~RTNoT values about a best-fit line drawn as described in Regulatory Position 2.1 normally should be less than l 7°F for plates. Even if the fluence range is large (two or more orders of magnitude), the scatter should not exceed twice that value. Even if the data fail this criterion for use in shift calculations, they may be credible for determining decrease in upper shelf energy if the upper shelf can be clearly determined, following the definition given in ASTM E185-82

[A-2-8]

For plate material C2307-2, there are 2 surveillance capsule data sets currently available.

The functional form of the least squares fit method as described in Regulatory Position 2.1 is utilized to determine a best-fit line for this data and to determine if the scatter of these ~TNoT values about this line is less than l7°F for plates. Figure A-2-4presents the best-fit line as described in Regulatory Position 2.1 utilizing the shift prediction routine from CVGRAPH, Version 5.0.2.

The scatter of ~T NDT values about the functional form of the best-fit line drawn as described in Regulatory Position 2.1 is presented in Table A-2-6.

(( (( }} Yes C2307-2 { } 300° 0.211 52.20 (( }} (( }} Yes Table A-2-6 indicates that the scatter is within acceptable range for credible surveillance data. Therefore, plate heat C2307-2 meets this criterion. Criterion 4: The irradiation temperature of the Charpy specimens in the capsule should match the vessel wall temperature at the cladding/base metal interface within+ I - 25°F. .2 EC 16-046, Rev 1 Page 42 of76 Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 11 of 45 BWRVIP-78 [A-2-9] established the similarity of BWR plant environments in the BWR fleet. The annulus between the wall and the core shroud in the region of the surveillance capsules contains a mix of water returning from the core and feedwater. Depending on feedwater temperature, this annulus region is between 525°F and 535°F. This location of specimens with respect to the reactor vessel beltline is designed so that the reactor vessel wall and the specimens experience equivalent operating conditions such that the temperature will not differ by more than 25°F. Any plant-specific exceptions to this generic.analysis should be evaluated. 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. Few ISP capsules contain correlation monitor material. Generally, this criterion is not applicable. For plate heat C2307-2, these criteria are satisfied (or not applicable). The surveillance data are nominally credible because the scatter criterion is met. Prior to application of the data, a plant should verify that no plant-specific exceptions to these criteria exist.

The T30 [30 ft-lb Transition Temperature], T50[50 ft-lb Transition Temperature], and T35mil [35 mil Lateral Expansion Temperature] have been determined for each Charpy data set, and each irradiated set is compared to the baseline (unirradiated) index temperatures. The change in Upper Shelf Energy (USE) is also shown. The unirradiated and irradiated values are taken from the CV GRAPH fits presented at the end of this sub-appendix (only CVN energy fits are presented). Comparison of Actual vs. Predicted Embrittlement A predicted shift in the 30 ft-lb transition temperature (~T30) is calculated for each irradiated data set using the Reg.

.2 EC 16-046, Rev 1 Page 55 of 76 Credibility of Surveillance Data Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 24 of45 The credibility of the surveillance data is determined according to the guidance of Regulatory Guide 1.99, Rev. 2 and 10 CFR 50.61, as supplemented by the NRC staff [A-19-8]. The following evaluation is based on the available surveillance data for irradiated plate heat C233 l-2. The applicability of this evaluation to a particular BWR plant must be confirmed on a plant-by-plant basis to verify there are no plant-specific exceptions to the following evaluation. Per Regulatory Guide 1.99, Revision 2 and 10 CFR 50.61, there are 5 criteria for the credibility assessment. Criterion 1: Materials in the capsules should be those judged most likely to be controlling with regard to radiation embrittlement. In order to satisfy this criterion, the representative surveillance material heat number must match the material in the vessel. 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 upper shelf energy unambiguously. Plots of Charpy energy versus temperature for the unirradiated and irradiated condition are presented in Figures A-19-1 through A-19-7. Based on engineering judgment, the scatter in these plots is small enough to permit the determination of the 30 ft-lb temperature and the upper shelf energy. Hence, this criterion is met. Criterion 3: When there are two or more sets of surveillance data from one reactor, the scatter of L1RTNDT values about a best-fit line drawn as described in Regulatory Position 2.1 normally should be less than l 7°F for plates. Even if the fluence range is large (two or more orders of magnitude), the scatter should not exceed twice that value. Even if the data fail this criterion for use in shift calculations, they may be credible for determining decrease in upper shelf energy if the upper shelf can be clearly determined, following the definition given in ASTM E185-82 [A-19-9]. For plate material C2331-2, there are 6 surveillance capsule data sets currently available. The functional form of the least squares fit method as described in Regulatory Position 2.1 is utilized to determine a best-fit line for this data and to determine if the scatter of these L1RTNDT values about this line is less than l 7°F for plates. Figure A-19-8 presents the best-fit line as described in Regulatory Position 2.1 utilizing the shift prediction routine from CVGRAPH, Version 5.0.2. The scatter of L1RTNDT values about the functional form of the best-fit line drawn as described in Regulatory Position 2.1 is presented in Table A-19-6. .2 EC 16-046, Rev 1 Page, 56 of 76 Table A-19-6 Best Fit Evaluation for Surveillance Plate Heat C2331-2 Measured Material Fitted Capsule FF ARTNDT CF (°F) (30 ft-lb) (°F) SSP D 0.419 62.0 SSPG 0.551 92.0 SSP E 0.534 76.1 C2331-2 { }} SSPI 0.644 93.7 SSPA 0.252 41.5 SSP B 0.286 34.7 Best Fit ARTNDT (oF) (( }} (( }} (( }} (( }} (( }} (( }} Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 25 of45 Scatter of <17°F (Base Metal) ARTNDT <28°F (oF) (Weld metal) (( }} Yes (( }} Yes (( }} Yes (( }} Yes (( }} Yes (( }} Yes Table A-19-6 indicates that the scatter is within acceptable range for credible surveillance data. Therefore, plate heat C2331-2 meets this criterion. Criterion 4: The irradiation temperature of the Charpy specimens in the capsule should match the vessel wall temperature at the cladding/base metal interface within+ I - 25°F. BWRVIP-78 [A-19-11] established the similarity of BWR plant environments in the BWR fleet. The annulus between the wall and the core shroud in the region of the surveillance capsules contains a mix of water returning from the core and feedwater. Depending on feedwater temperature, this annulus region is between 525°F and 535°F. This location of specimens with respect to the reactor vessel beltline is designed so that the reactor vessel wall and the specimens experience equivalent operating conditions such that the temperature will not differ by more than 25°F. Any plant-specific exceptions to this generic analysis should be evaluated. 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. Few ISP capsules contain correlation monitor material. Generally, this criterion is not applicable. For plate heat C2331-2, these criteria are satisfied (or not applicable). The surveillance data are nominally credible because the scatter criterion is met. Prior to application of the data, a plant should verify that no plant-specific exceptions to these criteria exist. .2 EC 16-046, Rev 1 Page 57 of76 Table A-19-7 Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 26 of45 Unirradiated Charpy V-Notch Results for Surveillance Plate C2331-2 (TL) Spec ID Temp (°F) CVN (ft-lb) LE (mils) %Shear SSP 1 -80 12.0 5.0 3 SSP2 -60 15.5 5.0 0 SSP3 -40 24.5 12.5 19 SSP4 -20 20.0 13.0 16 SSP5 -20 31.5 20.0 20 SSP6 0 43.5 28.5 23 SSP7 20 46.0 29.5 30 SSP8 40 52.5 32.5 49 SSP9 60 53.5 37.0 47 SSP 10 60 49.5 37.0 44 SSP 11 80 91.5 67.5 87 SSP12 100 86.0 63.0 89 SSP13 180 97.0 70.0 100 SSP14 300 97.0 73.0 100 SSP15 400 106.0 73.5 100 Table A-19-8 Charpy V-Notch Results for C2331-2 (TL) in SSP Capsule D Spec ID Temp (°F) CVN (ft-lb) LE (mils) %Shear 1 0 9 8 5 2 25 24.5 21 10 3 50 28 19 15 4 75 50.5 39 20 5 100 49 37 40 6 150 68 51 90 7 200 83.75 57 100 8 250 92.5 65 100 9 300 94 71 100 10 400 87 71 100 .2 EC 16-046, Rev 1 Page 58 of 76 Table A-19-9 Charpy V-Notch Results for C2331-2 (TL) in SSP Capsule G Spec ID Temp (°F) CVN (ft-lb) LE (mils) %Shear 1 25 18.5 15 5 2 75 33.5 24 20 3 100 35.5 27 10 4 125 41.5 35 35 5 140 51.5 37 40 6 150 63.5 47 70 7 200 76 57 100 8 250 84.5 58 100 9 300 83 70 100 10 400 83 65 100 Table A-19-10 Charpy V-Notch Results for C2331-2 (TL) in SSP Capsule E Spec ID Temp (°F) CVN (ft-lb) LE (mils) %Shear EP130C 0 10.5 1 0 EP130E 40 28.0 12 15 EP130A 70 27.5 17 30 EP130H 100 49.0 27 55 EP130D 125 54.5 32 50 EP130F 150 68.5 43 90 EP130B 200 80.0 55 100 EP130G 225 82.0 54 100 EP130I 250 81.5 61 100 EP130J 300 85.5 59 100 Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 27 of45 .2 EC 16-046, Rev 1 Page 59 of76 Table A-19-11 Charpy V-Notch Results for C2331-2 (TL) in SSP Capsule I Spec ID Temp ( 0 f) CVN (ft-lb) LE (mils) %Shear IP130B 0 8.5 2.0 0 IP130J 30 20.0 8.0 5 IP130A 70 27.5 14.0 20 IP130H 100 30.0 18.0 30 IP130G 125 50.5 37.0 55 IP130C 150 60.0 46.0 65 IP130D 200 71.5 54.0 85 IP1301 250 77.5 59.0 100 IP130E 300 83.0 69.0 100 IP130F 400 80.5 64.0 100 Table A-19*12 Charpy V-Notch Results for C2331-2 (TL) in SSP Capsule A Spec ID Temp ( 0 f) CVN (ft-lb) LE (mils) %Shear AP1-30-10 . -40.36 10.07 10.5 8.3 AP1-30-8 -20.56 15.78 16.0 11.9 AP1-30-7 19.94 30.17 28.5 21 AP1-30-9 19.94 33.14 30.5 20.7 AP1-30-1 67.64 39.22 39.0 26.9 AP1-30-2 110.84 57.99 52.0 47.4 AP1-30-3 160.70 85.95 73.0 99 AP1-30-4 250.88 88.94 77.0 100 AP1-30-5 300.74 90.17 73.0 100 AP1-30-6 399.56 99.00 76.5 100 Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 28 of45 .2 EC 16-046, Rev 1 Page 60 of76 Table A-19-13 Charpy V-Notch Results for C2331-2 (TL) in SSP Capsule B Spec ID Temp (°F) CVN (ft-lb) LE (mils) %Shear BP1-30-8 -20.20 10.03 10.0 9.3 BP1-30-10 0.32 27.15 26.0 16.6 BP1-30-7 20.48 35.30 31.0 19 BP1-30-1 68.00 46.36 39.5 36.2 BP1-30-9 89.60 60.70 55.5 37.7 BP1-30-2 120.74 82.25 66.0 73.8 BP1-30-3 180.32 90.96 72.0 100 BP1-30-4 249.44 100.08 81.0 100 BP1-30-5 299.66 99.12 77.0 100 BP1-30-6 400.28 100.70 74.5 100 Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 29 of45 .2 EC 16-046, Rev 1 Page 61 of 76 Tanh Curve Fits of CVN Test Data for Plate Heat C2331-2 UNIRRADIATED PLATE HEAT C2331-2 Appendix B, ER 2016-042 Cooper PTLR (Non-Proprietary) Page 30 of45 CV GRAPH 5.0.2 Hyperbolic Tangent Curve Printed on 06/23/2003 03:05 PM Page I 300 250 ~ 200
