Guide 1.99, Rev. 2. The maximum scatter in the fitted data is (( }} which is well within the 1-sigma value of l 7°F for plates as given in Reg. Guide 1.99, Rev. 2. 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 I-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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 5 of 45 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 B are provided in Appendix A-19. The credible surveillance data should be considered when a revised ART is calculated for vessel heat C2331-2. Summary of Available Surveillance Data: Weld The representative weld material 20291 is contained in the following ISP capsules: Cooper Capsules SSP Capsule C Specific surveillance data related to weld heat 20291 are presented in Appendix B-2 and the results are summarized below. Three capsules containing weld heat 20291 have been tested. The Charpy V-notch surveillance results are as follows: Table 2-24 T 30 Shift Results for Weld Heat 20291 Cu Ni Fluence Capsule 11 tiTao(°F) (wt%) (wt%) (10 n/cm2, E > 1 MeV) Cooper 30° 2.4 60.9 Cooper 300° 0.23 0.75 2.8 63.8 SSPC 3.29 73.0 The results given in Appendix B-2 show a fitted chemistry factor (CF) of (( } }, as compared to a value of 194.5°F from the chemistry tables in Reg. Guide 1.99, Rev. 2. The maximum scatter in the fitted data is well within the I-sigma value of28°F for welds as given in Reg. Guide 1.99, Rev. 2. Conclusions and Recommendations 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 ofISP surveillance data are provided in Section 3 of this Data Source Book.

   'From Reference [A-2-1 ], which updated and superseded the fluence provided by Reference [A-2-2] for this capsule.

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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 7 of 45 Effects of Irradiation The radiation induced transition temperature shifts for heat C2307-2 are shown in Table A-2-3. The T30 [30 ft-lb Transition Temperature], T 50 [50 ft-lb Transition Temperature], and T35 mil [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 (LlT30 ) 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 LlT30 (°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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 10 of45 Per Regulatory Guide 1.99, Revision 2 and IO 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 t1RTNoT 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 El85-82 [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 t1RTNoT values about this line is less than 17°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 ~RTNoT 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.

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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 11 of45 BWRVIP-78 [A-2-9] established the similarity ofBWR 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 feed water. 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 source documents for the data are provided, and the capsule designation and fluence values are also provided for irradiated data sets. Table A-19-1 ISP Capsules Containing Plate Heat C2331-2 17 Capsule Fluence (E> 1 MeV, 10 n/cm') Reference Unirradiated Baseline Data - Reference A-19-1 SSPD 10.118 Reference A-19-2 SSPG 18.487 SSP E 17.192 Reference A-19-3 SSPI 27.085 SSPA 3.82 Reference A-1 9-12 SSP B 4.79 Reference A-19-12 The CVN test data for each set taken from the references noted above are presented in Tables A-19-7 through A-19-13. 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-19-4] and the plots are provided in Figures A-19-1 through A-19-7. Best Estimate Chemistry Table A-19-2 details the best estimate average chemistry values for plate heat C2331-2 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.

The T 30 [30 ft-lb Transition Temperature], T 50 [50 ft-lb Transition Temperature], and T 35 mu [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 unitrndiated and irradiated values are taken from the CVGRAPH 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 (L1T30) is calculated for each irradiated data set using the Reg. Guide 1.99, Rev. 2, Regulatory Position 1.1 method. Table A-19-4 compares the predicted shift with the measured L1T30 (°F) taken from Table A-19-3. Decrease in USE Table A-19-5 shows the percent decrease in upper shelf energy (USE). The measured percent decrease is calculated from the values presented in Table A-19-3.

Margin= 2-J(a, +at!), where er,= the standard deviation on initial RTNoT (which is taken to be 0°F), and er,. is the standard deviation on iiRTNor (28°F for welds and 17°F for base materials, except that er,. need not exceed 0.50 times the mean value of iiRTN 0 ,). Thus, margin is defined as 34°F for plate materials and 56°F for weld materials, or margin equals shift (whichever is less), per Reg. Guide 1.99, Rev. 2.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 24 of 45 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-19-8]. The following evaluation is based on the available surveillance data for irradiated plate heat C2331-2. 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 I: 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 ~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 El 85-82 [A-19-9]. For plate material C233 l-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 ~RTNoT values about this line is less than 17°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 .ilRTNoT 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.

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 feed water. 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 IS.P capsules contain correlation monitor material. Generally, this criterion is not applicable. For plate heat C233 l-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.

Guide 1.99, Rev. 2. The maximum scatter in the fitted data is (( }} which is well within the 1-sigma value of l 7°F for plates as given in Reg. Guide 1.99, Rev. 2. 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 I-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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 5 of 45 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 B are provided in Appendix A-19. The credible surveillance data should be considered when a revised ART is calculated for vessel heat C2331-2. Summary of Available Surveillance Data: Weld The representative weld material 20291 is contained in the following ISP capsules: Cooper Capsules SSP Capsule C Specific surveillance data related to weld heat 20291 are presented in Appendix B-2 and the results are summarized below. Three capsules containing weld heat 20291 have been tested.

Guide 1.99, Rev. 2. The maximum scatter in the fitted data is well within the I-sigma value of28°F for welds as given in Reg. Guide 1.99, Rev. 2. Conclusions and Recommendations 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 ofISP 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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 7 of 45 Effects of Irradiation The radiation induced transition temperature shifts for heat C2307-2 are shown in Table A-2-3. The T30 [30 ft-lb Transition Temperature], T 50 [50 ft-lb Transition Temperature], and T35 mil [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 (LlT30 ) 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 LlT30 (°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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 10 of45 Per Regulatory Guide 1.99, Revision 2 and IO 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 t1RTNoT 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 El85-82 [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 t1RTNoT values about this line is less than 17°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 ~RTNoT 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.

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.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 11 of45 BWRVIP-78 [A-2-9] established the similarity ofBWR 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 feed water. 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 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-19-4] and the plots are provided in Figures A-19-1 through A-19-7. Best Estimate Chemistry Table A-19-2 details the best estimate average chemistry values for plate heat C2331-2 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.

The T 30 [30 ft-lb Transition Temperature], T 50 [50 ft-lb Transition Temperature], and T 35 mu [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 unitrndiated and irradiated values are taken from the CVGRAPH 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 (L1T30) is calculated for each irradiated data set using the Reg. Guide 1.99, Rev. 2, Regulatory Position 1.1 method. Table A-19-4 compares the predicted shift with the measured L1T30 (°F) taken from Table A-19-3. Decrease in USE Table A-19-5 shows the percent decrease in upper shelf energy (USE). The measured percent decrease is calculated from the values presented in Table A-19-3.

ER 15-019, Supplement 1 Cooper PTLR (Non-Proprietary) Page 24 of 45 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-19-8]. The following evaluation is based on the available surveillance data for irradiated plate heat C2331-2. 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 I: 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 ~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 El 85-82 [A-19-9]. For plate material C233 l-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 ~RTNoT values about this line is less than 17°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 .ilRTNoT 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.

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 feed water. 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 IS.P capsules contain correlation monitor material. Generally, this criterion is not applicable. For plate heat C233 l-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.
