Westinghouse Non-Proprietary Class 3 D-1 APPENDIX D ST. LUCIE UNIT 2 SURVEILLANCE PROGRAM CREDIBILITY EVALUATION D.1 INTRODUCTION Regulatory Guide 1.99, Revision 2 [Ref, D- 1] describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of the low-alloy steels currently used for light-water-cooled reactor vessels. Positions 2.1 and 2.2 of Regulatory Guide 1.99, Revision 2, describe the method for calculating the adjusted, reference temperature and Charpy upper-shelf energy of reactor vessel beltline materials using surveillance capsule data. The methods of Positions 2.1 and 2.2 can only be applied when two or more credible surveillance data sets become available from the reactor in question. To date there have been three surveillance capsules removed and tested from the St. Lucie Unit 2 reactor vessel. To use these surveillance data sets, they must be shown to be credible. In accordance with Regulatory Guide 1.99, Revision 2, the credibility of the surveillance data will be judged based on five criteria. The purpose of this evaluation is to apply the credibility requirements of Regulatory Guide 1.99, Revision 2, to the St. Lucie Unit 2 reactor vessel surveillance data and determine if that surveillance data is credible. D.2 EVALUATION Criterion 1: Materials in the capsules should be those judged most likely to be controlling with regard to radiation embrittlement. The beltline region of the reactor vessel is defined in Appendix G to 10 CFR Part 50, "Fracture Toughness Requirements" [Ref. D-2], as follows:

         "the region of the reactor vessel (shell material including welds, heat affected zones, and plates orforgings) that directly surrounds the effective height of the active core and adjacent regions of the reactor vessel that are predicted to experience sufficient neutron radiation damage to be considered in the selection of the most limiting materialwith regardto radiationdamage."

WCAP- 17939-NP May 2015 Revision 0

Westinghouse Non-Proprietary Class 3 D-2 The St. Lucie Unit 2 reactor vessel beltline region consists of the following materials:

1. Intermediate Shell Plates M-605-1, M-605-2, and M-605-3

2. Lower Shell Plates M-4116-1, M-4116-2, and M-4116-3

3. Intermediate Shell Axial Welds (Heat # 83642, Flux Type Linde 0091)

4. Intermediate Shell Axial Weld Repair (Heat # 83637, Flux Type Linde 0091)

5. Intermediate to Lower Shell Girth Weld (Heat # 83637 and 3P7317, Flux Type Linde 124)

6. Lower Shell Axial Welds (Heat # 83637, Flux Type Linde 0091)

Per WCAP-1 5040, Revision 1 [Ref. D-3], the St. Lucie Unit 2 surveillance program was developed to the requirements of ASTM El185-73. Intermediate shell plate M-605-1 had the highest initial RTNDT value and the second highest Cu wt. % value. This plate is also the same heat of material as the intermediate shell plate M-605-3; therefore, it is also representative of a second beltline plate. Intermediate shell plate M-605-2 has a higher wt. % Cu value; however, it has superior fracture toughness properties (Initial USE and RTNDT) as compared to plate M-605-1. Lastly, all three lower shell plates, while having less than or equivalent initial USE values, have lower initial RTNDT values and significantly better wt. % Cu values when compared to plate M-605-1. Hence, the intermediate shell plate M-605-1 was chosen as the most limiting plate material. The surveillance weld metal was selected as Heat # 83637, Flux Type Linde 124, Lot # 0951. The selection of this weld material was the general practice for Combustion Engineering surveillance programs because it was considered representative material, even though this material is not directly applicable to any of the reactor vessel beltline welds. The vessel welds fabricated using the same weld wire heat, 83637, are the intermediate shell axial weld repair, and the lower shell axial welds. However, these welds all used a different Flux Type: Linde 0091 for the reactor vessel and Linde 124 for the surveillance weld. The intermediate to lower shell girth weld seam used the same heat and flux type; however, this weld was made with a second weld wire, heat # 3P7317, making the surveillance weld only partially applicable to the vessel. Hence, weld wire Heat # 83637, Flux Type Linde 124 (flux lot # 0951) was utilized in the surveillance program. Based on the above discussion and the methodology in use at the time the program was developed, the St. Lucie Unit 2 surveillance material meets the intent of Criterion 1. Criterion 2: Scatter in the plots of Charpy energy versus temperature for the irradiated and unirradiated conditions should be small enough to permit the determination of the 30 ft-lb temperature and upper-shelf energy unambiguously. Based on engineering judgment, the scatter in the data presented in these plots is small enough to permit the determination of the 30 ft-lb temperature and the USE of the St. Lucie Unit 2 surveillance materials unambiguously. Hence, the St. Lucie Unit 2 surveillance program meets this criterion. WCAP-17939-NP May 2015 Revision 0

Westinghouse Non-Proprietary Class 3 D-3 Criterion 3: When there are two or more sets of surveillance data from one reactor, the scatter of ARTNDT values about a best-fit line drawn as described in Regulatory Position 2.1 should normally be less than 28 0 F for welds and 17°F for base metal. Even if the fluence range is large (two or more orders of magnitude), the scatter should not exceed twice those values. Even if the data fail this criterion for use in shift calculations, they may be credible for determining decrease in USE if the upper shelf can be clearly determined, following the definition given in ASTM E185-82 [Ref. D-4]. The functional form of the least-squares method as described in Regulatory Position 2.1 will be utilized to determine a best-fit line for this data and to determine if the scatter of these ARTNDT values about this line is less than 287F for welds and less than 177F for the plate. Following is the calculation of the best-fit line as described in Regulatory Position 2.1 of Regulatory Guide 1.99, Revision 2. In addition, the recommended NRC methods for determining credibility will be followed. The NRC methods were presented to industry at a meeting held by the NRC on February 12 and 13, 1998 [Ref. D-5]. At this meeting the NRC presented five cases. Of the five cases, Case 1 ("Surveillance data available from plant but no other source") most closely represents the situation for the St. Lucie Unit 2 surveillance plate and weld material. Furthermore, per ASTM E185-82, only transverse orientation base metal is required to be included in surveillance capsules. In addition, ASME Code requires that initial RTNDT and USE be determined via testing of Charpy V-notch specimens oriented in the transverse direction. Therefore, even though 10 CFR 50.61 states that "Surveillance program results means any data that demonstrates the embrittlement trends for the limiting beltline material, including but not limited to data from test reactors or from surveillance programs at other plants with or without surveillance program integrated per 10 CFR Part 50, Appendix H," ASTM E185-82 suggests inclusion of a greater quantity of Charpy V-notch test specimens, whenever possible (which was done for St. Lucie Unit 2). The longitudinal orientation Charpy V-Notch test results do demonstrate embrittlement trends for the limiting beltline plate material. Consistent with 10 CFR 50.61, the longitudinal and transverse orientation plate data are all considered in Tables D-1 and D-2. As an altemative presentation of the plate data, an interim chemistry factor and credibility conclusion is presented in Tables D-3 and D-4 using only the transverse orientation base metal Charpy V-notch test results. WCAP-17939-NP May 2015 Revision 0

Westinghouse Non-Proprietary Class 3 D-4 Case 1: Intermediate Shell Plate M-605-1 and Weld Heat # 83637 Following the NRC Case 1 guidelines, the St. Lucie Unit 2 surveillance plate and weld metal (Heat # 83637) will be evaluated using the St. Lucie Unit 2 data. This evaluation is contained in Table D-1. Note that when evaluating the credibility of the surveillance weld data, the measured ARTNTDT values for the surveillance weld metal do not include the adjustment ratio procedure of Regulatory Guide 1.99, Revision 2, Position 2.1, since this calculation is based on the actual surveillance weld metal measured shift values. In addition, only St. Lucie Unit 2 data is being considered; therefore, no temperature adjustment is required.

Table D-4 indicates that only one of the three surveillance data points falls outside the +/- 1ca of 17'F scatter band for surveillance base metals. With consideration of the three points, 67% of the data is within the 17'F scatter band. The one data point that falls outside of the scatter band is by 2.40 F, which is a small amount considering that the scatter band is 34°F (+/- 17°F). Furthermore, the two data points that are at fluence levels closer to the actual current vessel fluence and projected end of 40-year life fluence have very minimal scatter (2.6°F and 5.5°F). Since comparisons of the measured and predicted shifts for the two most recent data points have minimal scatter, it is reasonable to state that the transverse plate data only is deemed "credible" per the third criterion. WCAP- 17939-NP May 2015 Revision 0

Westinghouse Non-Proprietary Class 3 D-7 Criterion 4: The irradiation temperature of the Charpy specimens in the capsule should match the vessel wall temperature at the cladding/base metal interface within +/- 25'F. The surveillance materials are contained in capsules positioned near the reactor vessel inside wall so that the irradiation conditions (fluence, flux spectrum, temperature) of the test specimens resemble, as closely as possible, the irradiation conditions of the reactor vessel. The capsules are bisected by the midplane of the core and are placed in capsule holders positioned circumferentially about the core at locations near the regions of maximum flux. The location of the specimens with respect to the reactor vessel beltline provides assurance that the reactor vessel wall and the specimens experience equivalent operating conditions such that the temperatures will not differ by more than 25 0 F. Hence, Criterion 4 is met for the St. Lucie Unit 2 surveillance program. Criterion 5: The surveillance data for the correlation monitor material in the capsule should fall within the scatter band of the database for that material. The St. Lucie Unit 2 surveillance program does contain Standard Reference Material (SRM). The material was obtained from an A533 Grade B, Class 1 plate (HSST Plate 01). NUREG/CR-6413, ORNL/TM-13133 [Ref. D-6] contains a plot of Residual vs. Fast Fluence for the SRM (Figure 11 in the report). This Figure shows a 2cr uncertainty of 50'F. The data used for this plot is contained in Table 14 in the report. However, the NUREG Report does not consider the recalculated fluence and ARTNDT values for Capsule 2630. Thus, Table D-5 contains an updated calculation of Residual vs. Fast fluence, considering the recalculated capsule fluence and ARTNDT values for Capsule 2630.

(c) Residual = Absolute Value [Measured Shift - RG 1.99 Shift]. Table D-5 shows a 2a uncertainty of less than 50°F, which is the allowable scatter in NUREG/CR-6413, ORNL/TM-13133. Hence, Criterion 5 is met for the St. Lucie Unit 2 surveillance program. May 2015 WCAP- 17939-NP WCAP- 17939-NP May 2015 Revision 0

Westinghouse Non-Proprietary Class 3 D-8 D.3 CONCLUSION Based on the preceding responses to all five criteria of Regulatory Guide 1.99, Revision 2, Section B, the St. Lucie Unit 2 surveillance plate, with consideration of all surveillance data or considering only the transverse orientation Charpy data points, and weld data are both deemed credible.

Westinghouse Non-Proprietary Class 3 E-1 APPENDIX E ST. LUCIE UNIT 2 UPPER-SHELF ENERGY EVALUATION E.1 EVALUATION Per Regulatory Guide 1.99, Revision 2 [Ref. E-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 E- 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 upper-shelf energy may be obtained by plotting the reduced plant surveillance data on Figure 2 of the Guide (Figure E- 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 55 EFPY (end-of-license) upper-shelf energy of the vessel materials can be predicted using the corresponding I/4T fluence projection, the copper content of the beltline materials and/or the results of the capsules tested to date using Figure 2 in Regulatory Guide 1.99, Revision 2. The maximum vessel clad/base metal interface fluence value was used to determine the corresponding 1/4T fluence value at 55 EFPY. The St. Lucie Unit 2 reactor vessel beltline region minimum thickness is 8.625 inches. Calculation of the 1/4T vessel fluence values at 55 EFPY for the beltline materials is shown as follows: Maximum Vessel Fluence @ 55 EFPY - 4.53 x 1019 n/cm 2 (E > 1.0 MeV) 1/4T Fluence @ 55 EFPY = 2 (4.53 x 1019 n/cm )

e(-0.24 * (8.625 / 4))

                                            =     2.700 x 1019 n/cm 2 (E > 1.0 MeV)

The following pages present the St. Lucie Unit 2 upper-shelf energy evaluation. Figure E-1, as indicated above, is used in making predictions in accordance with Regulatory Guide 1.99, Revision 2. Table E- 1 provides the predicted upper-shelf energy values for 55 EFPY (EOL). May 2015 17939-NP WCAP- 17939-NP May 2015 Revision 0

In calculating the Position 1.2 percent USE decreases, the copper weight percent values were conservatively rounded up to the next highest line for each plate and weld material. (b) Calculated using surveillance capsule measured percent decrease in USE from Table 5-10 and Regulatory Guide 1.99, Revision 2, Position 2.2; see Figure E-I. Consistent with Criterion I of Appendix D, the surveillance weld percent USE decrease was not applied to the reactor vessel weld materials because none of the actual reactor vessel welds directly match both the heat and flux type used for the surveillance weld material.
