| | |
| ==Dear Sir or Madam:==
| |
| On February 11, 2010, Entergy Nuclear Operations, Inc. (ENO) and the Nuclear Regulatory Commission (NRC) had a conference call to discuss ENO plans to revise the Palisades Nuclear Plant (PNP) pressurized thermal shock (PTS) analysis.
| |
| During the conference call, a future meeting at the NRC was proposed to discuss in more detail ENO plans to revise the PTS analysis.
| |
| Subsequently, a meeting was scheduled between ENO and the NRC on June 22, 2010. The attached documentation is provided in support of the meeting. Attached you will find (1) a PNP reactor vessel fluence evaluation, (2) a preliminary PTS screening criteria assessment, (3) a documented review of the PTS screening criteria assessment, (4) a list of ENO representatives planning to attend the meeting, and (5) a meeting agenda. The attachments contain no proprietary information.

Planned Meeting Agenda cc: Administrator, Region III, USNRC Project Manager, Palisades, USNRC Resident Inspector, Palisades, USNRC ATTACHMENT 1 Background Information 3 pages follow Background Information On March 22, 2005 (ADAMS accession no. ML050940446), Nuclear Management Company, LLC (former plant operator) submitted a license renewal application (LRA) to the Nuclear Regulatory Commission (NRC) to renew the operating license for the Palisades Nuclear Plant (PNP). The LRA included discussion of a time limiting aging analysis (TLAA) for pressurized thermal shock (PTS) of the PNP reactor pressure vessel (RPV). NRC issued a safety evaluation report (SER) related to the license renewal of the PNP on September 28,2006 (ML06271 0068). In January 2007, NRC issued NUREG-1871, "Safety Evaluation Report Related to the License Renewal of Palisades Nuclear Plant" (ML070600578).
| |
| In the SER, it is noted that the RPV is projected to exceed the PTS screening criteria in 2014. The axial welds at the 60° locations, fabricated with weld wires of heat W5214, are the limiting materials in the beltline region of the PNP RPV. The SER states that if an RPV is projected to exceed the PTS screening criteria, 10 CFR 50.61(b)(3) requires flux reduction be implemented reasonably practicable to avoid exceeding the PTS screening criteria.
| |
| If the flux reduction program does not prevent the RPV from exceeding the PTS screening criteria before the end of the operating license, the applicant, in order to meet PTS requirements, can choose in 10 CFR 50.61 between two options: 1. Submittal of a plant-specific safety analysis, pursuant to 10 CFR 50.61 (b)(4), to determine what, if any, modifications to equipment, systems, and plant operation are necessary to prevent failure of the RPV from a postulated PTS event. This analysis must be submitted at least three years before RT PTS is projected to exceed the PTS screening criteria.
| |
| : 2. Perform a thermal annealing treatment of the RPV, pursuant 10 CFR 50.61 (b )(7), to recover fracture toughness.
| |
| However, recognizing that the RPV welds are expected to exceed 10 CFR 50.61 PTS screening criteria during the period of extended operation, Entergy Nuclear Operations (ENO)(current plant owner) has chosen the 10 CFR 54.21 (c)(1 )(iii) option for managing the PTS TLAA. Per Section 4.2.2.2 of the SER, this option involved the following activities:
| |
| a) An assessment of the current licensing basis TLAA for PTS, b) A discussion of the flux reduction program implemented in accordance with 10 CFR 50.61 (b )(3), and c) An identification of viable options for managing the aging effect in the future ("Pressurized Thermal Shock Analyses for Renewal of Certain Nuclear Power 1 of 3 Plant Operating Licenses," Executive Director Memo to Commissioners, dated May 27, 2004, ML041190564).
| |
| The license renewal SER states that, prior to exceeding the PTS screening criteria limit, PNP will select the best option to manage PTS in accordance with NRC regulations and make required submittals to obtain NRC review and approval.
| |
| Subsequent to NRC approval of the LRA, the NRC issued 10 CFR 50.61 a to provide an alternative method for evaluating PTS for plants projected to exceed the screening criteria limit. ENO intends to use this alternative method for evaluating PTS for the PNP RPV at the appropriate time to meet the regulation.
| |
| The purpose of the scheduled June 22, 2010, meeting with the NRC is to discuss the status of activities recently completed and planned in the near future; under 10 CFR 54.21 (c)(1 )(iii), involving the PTS analysis.
| |
| Activities recently completed include: . 1. An update of Westinghouse Report, WCAP-15353, "Palisades Reactor Pressure Vessel Neutron Fluence Evaluation," Revision 0, January, 2000, to account for actual capacity factors and core loading patterns since that time. The update is documented in WCAP-15353-Supplement 1-NP, "Palisades Reactor Pressure Vessel Fluence Evaluation," Revision 0, April 2010 (Attachment 2). 2. An assessment of embrittlement for the limiting axial weld heat number W5214 relative to the PNP RPV. A new preliminary assessment for the RPV projecting RT PTS and the revised date when weld heat W5214 will exceed the PTS screening criteria of 270°F is contained in Structural Integrity Associates (SIA) Report No. 0901132.401, "Evaluation of Surveillance Data for Weld Heat No. W5214 for Application to Palisades PTS Analysis," Revision 0, April 2010 (Attachment 3). This new preliminary assessment uses the updated fluence evaluation performed by Westinghouse and all available surveillance data relevant to the PNP RPV limiting axial weld heat number W5214 as permitted by 10 CFR 50.61 (c)(2). A review of this report was performed by Westinghouse (Attachment 4). The preliminary SIA PTS screening assessment report indicates that, based on the new information, the revised projected date for the PNP RPV to reach the PTS screening criteria limit of 270°F would be approximately April 2017 or later. 2 of 3 10 CFR 50.61 (c)(3) states that any information believed to improve the accuracy of the RT PTS value significantly must be reported to the NRC and any value or RT PTS that has been modified using the procedures of 10 CFR 50.61 (c)(2) is subject to NRC approval.
| |
| In accordance with 10 CFR 50.61 (c)(3), at a later date, END plans to report new information that improves the accuracy of the RT PTS value to the NRC and to submit the updated fluence evaluation and the new PTS screening assessment report for NRC review and approval.
| |
| Based upon this new projection when the PNP RPV will reach the PTS screening criteria, ENG has identified the need for the following future activities:
| |
| : 1. Reschedule of the volumetric inspection for the PNP RPV from the fall 2010 refueling outage to the spring 2012 refueling outage. 2. Update and submit the PNP RPV heatup and cooldown curves located fn the PNP Technical Specifications for operation through spring 2017. 3. Following inspection of the PNP RPV in spring 2012, perform an assessment of the PNP RPV in accordance with 10 CFR 50.61 a. 4. Following NRC review and approval of the PTS assessment of the PNP RPV under 10 CFR 50.61 a, update and transmit the PNP RPV heatup and cooldown curves located in the PNP Technical Specifications for operation through the balance of the extended licensed life of the plant. The ultrasonic inspection of the PNP RPV planned in the spring of 2012 and subsequent evaluation and submittal in accordance with 10 CFR 50.61a will satisfy the PTS regulatory requirements through the remaining period of extended operation.

| ==SUMMARY==
| |
| Calculations of the neutron exposure of the Palisades reactor pressure vessel were previously completed and documented in WCAP-15353, Revision 0, "Palisades Reactor Vessel Neutron Fluence Evaluation," January 2000Y] This evaluation was submitted for review by the NRC Staff and, after consideration of RAI's addressed in Reference 4, the fluence methodology as well as the final results were approved by the Staff. The f1uence' analysis described in WCAP-15353, Revision 0[3] included cycle specific evaluations through Cycle 14 (the then current operating cycle). This supplement to WCAP-15353 provides an updated neutron fluence assessment for the Palisades pressure vessel beltline region that includes cycle specific analysis for additional operating cycles for which the design has been finalized (Cycles 15 through 21) and includes projections for future operation through approximately 44 effective full power years (EFPY). Updated evaluations of surveillance capsule credibility analysis and determination of material chemistry factors are being completed in parallel with this fluence calculation and will be documented elsewhere.
| |
| Based on the cycle specific analysis through Cycle 21 (approximately 23.4 EFPY) and the projection scenario for future operation provided by Entergy, the maximum neutron exposure of the pressure vessel beltline materials through 44 EFPY is summarized as follows.

| |
| | |
| In the assessment of the state of embrittlement of light water reactor (LWR) pressure vessels, an accurate evaluation of the neutron exposure of each of the materials comprising the beltline region of the vessel is required.
| |
| In Appendix G to 10 CFR 50[1], the beltline region is defined as "the region of the reactor vessel shell material (including welds, heat affected zones, and plates or forgings) that directly surrounds the effective height of the reactor core and adjacent regions of the reactor vessel that are predicted to experience sufficient neutron radiation damage to be considered in the selection of the most limiting material with regard to radiation damage". Each of the materials comprising the beltline region must be considered in the overall embrittlement assessments for the pressure vessel. Therefore, plant-specific exposure assessments must include evaluations as a function of position over the beltline region. Regulatory Guide 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence" [2], describes state-of-the-art calculation and measurement procedures that are acceptable to the NRC staff for determining pressure vessel fluence. Also included in Regulatory Guide 1.190 is a discussion of the steps required to qualify and validate the methodology used to determine the neutron exposure of the pressure vessel wall. One important step in the validation process is the comparison of plant-specific neutron calculations with available measurements.
| |
| In early 2000, WCAP-15353, Revision 0[3] describing the methodology used in the fluence evaluations for the Palisades plant was submitted to the NRC staff for review. Subsequent to that review and a further exchange of information documented in Reference 4, the methodology described in WCAP-15353, Revision 0 was approved for application to the Palisades reactor pressure vessel. Subsequent to that approval additional submittals[7,B]
| |
| in support of the benchmarking of this fluence methodology were reviewed and approved by the NRC Staff. , The fluence analysis described in WCAP-15353, Revision 0[3] included cycle specific evaluations through Cycle 14 (the then current operating cycle). This supplement to WCAP-15353 provides an updated neutron fluence assessment for the Palisades pressure vessel beltline region that includes cycle specific analysis for additional operating cycles for which the design has been finalized (Cycles 15 through 21) and includes projections for future operation through approximately 44 effective full power years (EFPY). The results of this evaluation are intended for use as input to vessel materials analyses (to be documented elsewhere) that include updates to surveillance capsule credibility analysis and material chemistry factor determination.

| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 1-2 Since the PTS screening criterion determination for the Palisades pressure vessel requires the evaluation of all weld heat W5214 surveillance capsule data from Palisades and other PWR's, this report also includes the latest fluence evaluation from capsules containing the W5214 material.
| |
| This compilation of capsule fluence values is based on the same fluence methodology described in this report. In subsequent sections of this supplement, the methodologies used to perform neutron transport calculations and dosimetry evaluations are described in some detail, the updated results of the plant specific transport calculations are given for the beltline region of the Palisades pressure vessel. Comparisons of calculations and measurements demonstrating that the transport calculations meet the requirements of Regulatory Guide 1.190 that were previously included in Reference 3 are also included in this supplement for completeness.
| |
| Finally, a listing of updated neutron fluence values based on the use of an approved Regulatory Guide 1.190 compliant fluence methodology for several previously withdrawn surveillance capsules that contain Palisades vessel materials is provided for use in data correlation studies. WCAP-15353

| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 2-1 SECTION 2.0 NEUTRON TRANSPORT CALCULATIONS As noted in Section 1.0 of this report, the exposure of the Palisades pressure vessel was developed based on a series of fuel cycle-specific neutron transport calculations validated by comparison with plant-specific measurements.
| |
| Measurement data used in the validation process were obtained from both in-vessel and ex-vessel capsule irradiations.
| |
| In this section, the neutron transport methodology is discussed in some detail, and the calculated results applicable to the in-vessel surveillance capsules and the pressure vessel beltline materials are presented.
| |
| A discussion of the Palisades dosimetry evaluations and measurement to calculation comparisons is included in Section 3.0 of this supplement.
| |
| 2.1 -Method of Analysis In performing the fast neutron exposure evaluations for the Palisades reactor, plant-specific forward transport calculations were carried out using the three-dimensional flux synthesis technique described in Section 1.3.4 of Regulatory Guide 1.190. In particular, the following single channel synthesis approach was employed for all fuel cycles: <P(r, z) <P(r, 8, z) = <P(r, 8) * <P(r) where is the synthesized three-dimensional neutron flux distribution, is the transport solution in r,e geometry, is the two-dimensional solution for a cylindrical reactor model using the actual axial core power distribution, and is the one-dimensional solution for a cylindrical reactor model using the same source-per-unit height as that used in the r,e two-dimensional calculation.
| |
| For the Palisades analysis, all of the transport calculations were carried out using the DORT two-dimensional discrete ordinates code Version 3.2[5] and the BUGLE-96 cross section library[6].
| |
| The BUGLE-96 library provides a 67-group coupled neutron-gamma ray cross-section data set produced specifically for light water reactor applications.
| |
| In these analyses, anisotropic scattering was treated with a P 5 legendre expansion and the angular discretization was modeled with an S16 order of angular quadrature.
| |
| The geometry used for the Palisades transport analysis is discussed in some detail in Reference 3 and the geometric model established for Cycle 15 and beyond was also used for the current evaluations.
| |
| A plan views of the r,e model of the reactor geometry at the core midplane is shown in Figure 2.1-1. This model depicts a single quadrant of the reactor. A section view of the r,z model of the Palisades reactor is shown in Figure 2.1-2. The model WCAP-15353
| |
| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 2-2 extended radially from the centerline of the reactor core out to a location interior to the primary biological shield and over an axial span from an elevation one foot below the active fuel to an axial elevation one foot above the active fuel. The one-dimensional radial model used in the synthesis procedure consisted of the same 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 the reactor were provided by Entergy.[15]
| |
| The data used in the source generation included fuel assembly-specific initial enrichments, beginning-of-cycle burnups and end-of-cycle burnups. Appropriate axial distributions were also obtained.
| |
| For each fuel cycle of operation, the fuel assembly-specific enrichment and burnup data were used to generate the spatially-dependent neutron source throughout the reactor core. This source description included the spatial variation of isotope dependent (U-235, U-238, Pu-239, Pu-240, Pu-241, and Pu-242) fission spectra, neutron emission rate per fission, and energy release per fission based on the burnup history of individual fuel assemblies.
| |
| These fuel assembly-specific neutron source strengths derived from the detailed isotopics were then converted from fuel pin cartesian coordinates to the [r,e], [r,z], and [r] spatial mesh arrays used in the DORT discrete ordinates calculations.
| |
| This same qualified methodology was used along with reactor specific input in the determination of the surveillance capsule fluence values discussed in Section 4.0 of this report. WCAP-15353

| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 2-5 2.2 -Calculated Neutron Exposure of Pressure Vessel Beltline Materials The plant-and fuel cycle-specific calculated fast neutron (E > 1.0 MeV) flux and fluence experienced by the materials comprising the beltline region of the Palisades pressure vessel is given in Tables 2.2-1 and 2.2-2, respectively, for plant operation through the conclusion of the twenty-first fuel cycle. Cycle 21 represents the last fuel cycle for which final fuel loading patterns have been designed.
| |
| As presented, the data in Tables 2.2-1 and 2.2-2 represent the maximum neutron exposures at the pressure vessel clad base metal interface at azimuthal angles of 0°, 15°, 30°, 45°, 60°, 75°, and 90° relative to the core major axes. The limiting weld material for the Palisades pressure vessel occurs along the 60° azimuth (Heat W5214, Weld IDs 2-112A/C and 3-112A1C).
| |
| All of the data provided in Tables 2.2-1 and 2.2-2 were taken at the axial location of the maximum exposure experienced at each azimuth based on the results of the dimensional synthesized neutron fluence evaluations.
| |
| In Table 2.2-3, projections of neutron (E > 1.0 MeV) fluence beyond the end of Cycle 21 are provided.
| |
| These projections were based on assumed future operating conditions provided by Entergy. In particular the following assumptions were applied to the analysis:
| |
| 1 -For Cycle 22, the nominal calculated neutron flux based on the average of the prior uprated fuel cycles (18 through 21) was used. This approach is a realistic representation of the neutron flux that would be expected based on existing preliminary designs for Cycle 22. 2 -For Cycles 23 and beyond, the Cycle 21 neutron flux distribution was applied for all fuel cycles. This is a conservative assumption in that, considering Cycles 15 through 21, the Cycle 21 power distribution results in the highest calculated flux at the location of the critical pressure vessel weld (60°). 3 -Projected fuel cycle lengths were provided by Entergy as follows: Design 95% Capacity 22 525 EFPD 499 EFPD Cycle 23 525 EFPD 499 EFPD Cycle 24 502 EFPD 477 EFPD Cycles 25+ 530 EFPD 504 EFPD Fuel cycles were assumed to operate with a breaker to breaker capacity factor of 95%. In completing the projections beyond the end of Cycle 21, operation was assumed to a total of 44 EFPY. Given the assumed operating scenario, this would cover a calendar time period extending to 2033.

| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 3-1 SECTION 3.0 NEUTRON DOSIMETRY EVALUATIONS During the first 14 operating fuel cycles at the Palisades plant, five sets of in-vessel surveillance capsule dosimetry and three sets of ex-vessel dosimetry were irradiated, withdrawn, and analyzed.
| |
| The results of these dosimetry evaluations provide a measurement data base that can be used to demonstrate that the neutron fluence calculations completed for the Palisades reactor meet the uncertainty requirements described in Regulatory Guide 1.190P1 That is, the calculations and measurements should agree within 20% at the 1 cr level. These calculation/measurement comparisons were previously completed and documented in Reference
| |
| : 3. However, for completeness, a brief description of the measurement program, dosimetry evaluation procedure, and final results are also included in this supplement to Reference
| |
| : 3. In addition to the Palisades dosimetry evaluations, this general methodology was also used in the determination of capsule exposures from the other PWR's included in Section 4.0 of this report. 3.1 -Method of Analysis Evaluations of neutron sensor sets contained in the in-vessel and ex-vessel dosimetry capsules withdrawn to date from the Palisades reactor were completed using current state-of-the art least-squares methodology that meet the requirements of Regulatory Guide 1.190[81.
| |
| These least-squares adjustment methods provide the capability of combining the measurement data with the neutron transport calculations resulting in a best estimate neutron energy spectrum with associated uncertainties.
| |
| Best estimates for key exposure parameters such as > 1.0 MeV) and iron atom displacement rate (dpa/s) along with their uncertainties are then c easily obtained from the adjusted spectrum.
| |
| In general, the least-squares methods, as applied to reactor 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, R; +/- 6 R , =
| |
| +/- 6(T)(¢g +/- 6¢) g relates a set of measured reaction rates, Rj, to a single neutron spectrum, through the multigroup dosimeter reaction cross section, crig, each with an uncertainty

| |
| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 3-2 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 Palisades dosimetry, the NRC approved methodology based on the use of the FERRET adjustment code[8] was employed to combine the results of the plant-specific neutron transport calculations and sensor set reaction rate measurements to determine best estimate values of exposure parameters along with associated uncertainties at the measurement locations.
| |
| 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 rate 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 Palisades application, the calculated neutron spectrum at each measurement location was obtained from the results of plant-specific neutron transport calculations based on the methodology described in section 2.0 of this report. The calculated spectrum at each sensor set location was input to the adjustment procedure 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.
| |
| The sensor reaction rates were derived from the measured specific activities of each sensor set and the operating history of the respective fuel cycles. The dosimetry reaction cross sections were obtained from the SNLRML dosimetry cross-section library. [9] e In addition to the magnitude of the calculated neutron spectra, the measured sensor set reaction rates, and the dosimeter set reaction cross sections, the least-squares procedure requires uncertainty estimates for each of these input parameters.
| |
| The following provides a summary of the uncertainties associated with the least-squares evaluation of the Palisades dosimetry.
| |
| Reaction Rate Uncertainties The overall uncertainty associated with the measured reaction rates includes components due to the basic measurement process, the irradiation history corrections, and the corrections for competing reactions.
| |
| A high level of accuracy in the reaction rate determinations is assured by utilizing laboratory procedures that conform to the ASTM national consensus standards for reaction rate determinations for each sensor type. WCAP-15353
| |
| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 3-3 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:

Dosimetry Cross-Section Uncertainties As noted above, 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 squares adjustment applications.
| |
| These cross sections were compiled from the most recent cross-section evaluations and they have been tested with respect to their accuracy and consistency for least-squares evaluations.
| |
| Further, the library has been empirically tested for use in fission spectra determination as well as in the f1uence and energy characterization of 14 MeV neutron sources. Detailed discussions of the contents of the SNLRML library along with the evaluation process for each of the sensors is provided in Reference

| -Supplement 1-NP, Revision 0 May 2010 Westinghouse Non-Proprietary Class 3 3-4 These tabulated ranges provide an indication of the dosimetry cross-section uncertainties associated with the sensor sets used in LWR irradiations.
| |
| Calculated Neutron Spectrum Uncertainties 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 R g , and Rg specify additional random groupwise uncertainties that are correlated with a correlation matrix given by: where H = (g_g')2 2r2 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 (8 specifies the strength of the latter term). The value of 0 is 1.0 when g = g' and 0.0 otherwise.
| |
| The set of parameters defining the input covariance matrix for the Palisades calculated spectra was as follows: Flux Normalization Uncertainty (Rn) c Flux Group Uncertainties (R g , R g ,) (E > 0.0055 MeV) (0.68 eV < E < 0.0055 MeV) (E < 0.68 eV) Short-Range Correlation (8) (E > 0.0055 MeV) (0.68 eV < E < 0.0055 MeV) (E < 0.68 eV) WCAP-15353

| |
| These comparisons are provided on two levels. In the first instance, calculations of individual sensor reaction rates are compared directly with the measured reaction rates derived from the counting data obtained from the radiochemical laboratories.
| |
| In the second case, the calculated values of neutron exposure expressed in terms of <I>(E > 1.0 MeV), <I>(E > 0.1 MeV), and iron atom displacements (dpa) are compared with the results of the least squares adjustment procedure described in Section 3.1. It is shown that these two levels of comparison yield consistent and similar results which demonstrate that the transport calculations for Palisades reactor produce neutron exposure results that meet the requirements of Regulatory Guide 1.190.[2]
| |
| In Table 3.2-1, measurement/calculation (M/C) ratios for each fast neutron sensor reaction from surveillance capsule and reactor cavity irradiations are listed. This comparison provides a direct comparison, on an absolute basis, of calculation and measurement prior to the application of the least squares adjustment procedure.
| |
| In Table 3.2-2, comparisons of measured and adjusted neutron exposures are given in terms of adjusted/calculated ratios for the five surveillance capsule dosimetry sets withdrawn to date as well as for the three cycles of reactor cavity midplane dosime\ry sets irradiated during Cycles 8, 9, and 10/11.

| Details of the analysis methodology as applied to each of the four host reactors are given in References 3, 12, 13, and 14. In providing the data listed in Table 4-1, no new fluence calculations were performed.
| |
| The data were obtained either from Palisades specific documents[10, 11] or from public domain documents[3, 12, 13, 14] that have been submitted to the NRC and are available on the ADAMS document system. It should be noted that, relative to the Palisades data listed in Table 4-1, References 3, 10, and 11 did not explicitly report fluence (E > 1.0 MeV) values for the individual capsules.
| |
| Rather, the irradiation environment was reported in terms of irradiation time and calculated neutron flux (E > 1.0 MeV) averaged over the irradiation period. The fluence values listed in Table 4-1 were computed as the product of the irradiation time and the average neutron flux reported in these documents.
| |
| Relative to the data in Table 4-1 and the listed references, it should also be noted that, in addition to the Reg. Guide 1.190 derived fluence values for Indian Point Unit 2, Table 3 of , Reference 12 also lists fluence values for H. B. Robinson Unit 2 and Indian Point Unit 3 that were extracted from older references.
| |
| These older values have been updated and superseded by the fluence values documented in References 13 and 14, respectively.

| ==SUMMARY==
| |
| This evaluation was perfonned as part of a review of the Palisades Pressurized Thermal Shock (PTS) re-evaluation.
| |
| A previous analysis perfonned for the Palisades vessel in 2000 determined that the PTS screening criteria limit of 270°F for weld heat No. W5214 would not be reached until January 2014. That evaluation was based on the fluence projections and weld material chemistry for weld heat No. W5214 available at that time; no credit was given for surveillance data to improve the RT PTS projection.
| |
| In the fall of 2009 it became apparent to Entergy that new infonnation was available that could affect the RTNDT of the limiting Palisades vessel beltline material.
| |
| The new data included revised fluence calculations and a total of eleven irradiated surveillance capsules that contain Charpy V -notch data for weld heat No. W5214. This report examines the updated fluence calculations perfonned by Westinghouse and all the available surveillance data relevant to the Palisades reactor pressure vessel weld heat No. W5214. Using the revised fluences and chemistry factors based on the refitted surveillance data for this weld heat, this re-evaluation shows that the projected date to reach the PTS screening criteria limit using the surveillance weld data would be approximately April 2017 or later.

| EVALUATION OF SURVEILLANCE DATA FOR WELD HEAT NO. W5214 FOR APPLICATION TO PALISADES PTS ANALYSIS
| |
| | |
| ==1.0 INTRODUCTION==
| |
| | |
| The Palisades Nuclear Plant submitted to NRC a Pressurized Thermal Shock (PTS) evaluation in 2000 that projected the value for RTpTs, or maximum Adjusted Reference Temperature (ART) of the limiting vessel weld or plate, based on the calculated fluences and material properties available at that time [1]. The limiting vessel belt1ine material was determined to be weld heat No. W5214, and the projected ART value was based on the method in the PTS Rule given in 10CFR50.61, Paragraph (c)(l) [2] using the best estimate chemistry for this weld, the corresponding chemistry factor, CF, and the fluence values from the vessel fluence evaluation in WCAP-15353
| |
| [3]. These inputs to the PTS Rule equations were used to calculate RT PTs , and the Palisades vessel was projected to reach the screening criterion limit of 270°F for the limiting weld in January 2014. Since the time that the previous PTS evaluation was performed for the Palisades vessel, ten years have passed and more data and information are available now to update the projected RTNDT value for the limiting Palisades vessel beltline material.
| |
| In particular, this evaluation considers all the available surveillance data for weld heat No. W5214 that can be used to refme the projected RTNDT in accordance with 10CFR50.61, Paragraph (c)(2) [2]. This evaluation is being updated now because there is new information that changes the projected values ofRT pTs for the Palisades vessel. The new information was generated by performing a survey of all relevant surveillance data for weld heat No. W5214. Eleven irradiated surveillance capsule reports were found containing this weld, and the Charpy data contained in these capsules was compiled and refitted consistently using the CVGRAPH hyperbolic tangent curve-fitting methodology
| |
| [4]. Also, the eleven capsule fluence values have been updated (over time) by Westinghouse using their NRC approved fluence methodology for implementing the Regulatory Guide 1.190 benchmarking procedure
| |
| [5]. AU data was evaluated in accordance with the PTS Rule approach to determine the shift values, fitted CF from the surveillance data, scatter from the mean predicted shift, and credibility of the data. It was determined that this new evaluation provides the most technically complete and sound assessment for the Palisades weld heat No. W5214 and allows for more accurate life projections of the limiting material in the Palisades vessel. The latest W5214 life projection provides improvement (i.e., more time) from the previous prediction to reach the PTS screening criterion limit. 2.0 APPLICABILITY This evaluation is applicable to the Palisades Reactor vessel PTS analysis relative to intermediate shell axial welds 2-112A1B/C fabricated from weld heat No. W5214 [1]. The results of this evaluation are used to revise the RTPTs projection to determine the maximum fluence, or Report No. 0901132.401, Rev. 0 1 '"'''''OnE'''''

| equivalent date, to reach the PTS screening criteron of 270°F for the limiting axial weld at the 60° azimuthal location.
| |
| Evaluation of other beltline region materials not performed at this time because they are not projected or expected to exceed the PTS screening criterion over the next several years. A complete PTS analysis for all of the vessel beltline materials will be performed at a later time per IOCFR50.61.
| |
| 3.0 METHODOLOGY 3.1 Charpy TANH Curve-Fitting Method All Charpy data has been re-evaluated to assure that the Charpy curve fits and the 30 ft-lb shift values from the surveillance capsule reports are performed in a consistent manner. The general shape of Charpy test data (energy versus temperature, or lateral expansion versus temperature) is that of an "S", generally with definable lower and upper shelves and a connecting region between the shelves called the transition region. The hyperbolic tangent (TANH) function has been used for some time as a simple statistical curve-fit tool to describe this "S"-shaped response [25]. Other functional relationships could have been used to produce a similar shape (e.g., an error function), but the benefit of the TANH function is that the curve fit parameters defining the "S" shape have physical meaning relative to what is generally evaluated from the test results. As a result, the hyperbolic TANH curve fitting ofCharpy V-notch (CV) impact energy data has been a standard practice within the industry.
| |
| The TANH model used for modeling Charpy V-notch curves is given by Equation (1) [25]: where, C v = A + B tanh [(T -To) / C] C v = Charpy V-notch impact energy T test temperature A = the'mean energy level between the upper and lower shelves B = the + or -deviation from the mean energy level To = a parameter that represents the mid-energy transition temperature (1) C = the + or -deviation of the intercepts of the tangent to the transition of To and the upper and lower shelves The lower shelf (A -B) was fixed at 2.2 ft-lb, and the upper shelf (A + B) was fixed III accordance with standard practice for applying hyperbolic tangent fits to Charpy V -notch data [24].

| |
| 3.2 Fluence Analysis Method The surveillance capsule fluence values were re-evaluated by Westinghouse using the DORT neutron transport calculation method which has been benchmarked to meet the criteria in NRC Regulatory Guide 1.190 [5], shows close agreement between calculations and neutron dosimetry measurements, and has been approved for use by NRC. The capsule fluence values were provided as design inputs by Westinghouse
| |
| [18]. 3.3 10CFR50.61 (PTS Rule) Embrittlement Prediction Methods The PTS Rule in lOCFR50.61
| |
| [2] provides two methods for determining the reference temperature.
| |
| The first method considers only the copper and nickel chemistry, fluence, and initial RTNDT of the weld, plate, or forging material in the reactor vessel beltline.
| |
| For those beltline materials, Equation (2) is used to determine the adjusted RTNDT for comparison to the PTS screening criteria limits. RTNDT = Initial RTNDT +
| |
| + Margin (2) where is the mean value of the transition temperature due to irradiation, and must be calculated using the Equation (3):
| |
| = (CF)f(o.28-0.101o g t) (3) where CF (OF) is the chemistry factor, which is a function of the copper and nickel content. CF is determined by using Table 1 (from lOCFR50.61) for welds and by using Table 2 (from 1 OCFR50.61) for base metals (plates and forgings). "Wt % copper" and "Wt % nickel" are the best-estimate values for the material, which will normally be the mean of the measured values for a plate or forging. For a weld, the best estimate values will normally be the mean of the measured values for a weld deposit made using the same weld wire heat number as the critical vessel weld. For weld heat number W5214, the best-estimate chemistry, as determined by the industry best-estimate results from the CEOG report [20], is Cu = 0.213 wt%, Ni = 1.007 wt%. The best-estimate chemistry values for the C-E fabricated welds are shown in Appendix A. The corresponding chemistry factor for this weld heat is CF = 230.73°F.
| |
| This value for best-estimate nickel content varies slightly from the value used previously in the PTS submittal (Ni = 1.01 %) [1]. It is noted that the basis for the best estimate Cu and Ni values came from the CEOG report [20] which is considered to be the industry standard for the C-E fabricated welds, but Palisades chose to round up the nickel content from 1.007% to 1.01 % in the 1998 RAI response to Generic Letter 92-01 [19]. For the current analysis we have also used the CEOG determined actual nickel best estimate chemistry which gives a CF value of230.73°F for comparison to a CF value of 231.08 of for the rounded up nickel content. Report No. 0901132.401, Rev. 0 3 :srl'l'!ffUII'JU InttH"JiI'ihl Associates, Inc.
| |
| The Initial RT NDT for weld heat No. WS214 is detennined from the generic value of -S6°F for C-E fabricated Linde 1092 flux type welds [31], and the margin tenn is detennined from Equation 4: Margin = 2
| |
| + (J"2 I (4) where aI is the standard deviation for the initial RT NDT. If the generic mean Initial RT NDT value for a Linde 1092 weld is used, then aI = 17°F [2]. The (I-sigma) standard deviation for i1RTNDT' at, , is 28°F for welds, so the margin tenn for this case is 6S.S0F. Using this approach to detennine the RT PTS at the screening criteria limit for axial welds (i.e., 270°F) yields a maximum allowable fluence at the 60° azimuthal weld location of: RTpTS = 270°F = Initial RTNDT + i1RTNDT + Margin = -S6 + L1RTNDT + (S) i1RTNDT = 260.soF = (CF) f(0.28-0.10 logf) = (230.73) f(0.28-0.10 logf) (6) (7) The second method for detennining the chemistry factor and the RT NDT states that, "To verify that R T NDT for each vessel beltline material is a bounding value for the specific reactor vessel, licensees shall consider plant-specific infonnation that could affect the level of embrittlement.
| |
| This infonnation includes but is not limited to the reactor vessel operating temperature and any related surveillance program results." 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 SO, appendix H. This is the case for Palisades; eleven previously tested surveillance capsules are now available that contain the limiting vessel weld heat No. WS214. The axial weld in the Palisades vessel made from weld heat No. WS214 was determined to C be the limiting vessel beltline material [1]. Results from the plant-specific surveillance program must be integrated into the RTNDT estimate if the plant-specific surveillance data has been deemed credible as judged by the following criteria [2]: (A) The materials in the surveillance capsules must be those which are the controlling materials with regard to radiation embrittlement, (B) Scatter in the plots of Charpy energy versus temperature for the irradiated and unirradiated conditions must be small enough to pennit the detennination of the 30-foot-pound temperature unambiguously, (C) Where there are two or more sets of surveillance data from one reactor, the scatter of RTNDT values must be less than 28°F for welds and 17°F for base metal. Even if the range Report No. 0901132.401, Rev. 0 4 Stflllctllfal, .. t'''1tll'i'f" Associates, Inc.
| |
| in the capsule fluences is large (two or more orders of magnitude), the scatter may not exceed twice those values (i.e., 56°F), (D) The irradiation temperature of the Charpy specimens in the capsule must equal the vessel wall temperature at the claddinglbase metal interface within 25°F, and (E) The surveillance data for the correlation monitor material in the capsule, if present, must fall within the scatter band of the data base for the material.
| |
| Surveillance data deemed credible according to these criteria must be used to determine a material-specific value of CF for use in Equation (2). A material-specific value of CF is determined from Equation (8) [19]. '£ [AI x

(8) If there is clear evidence that the copper and nickel content of the surveillance weld differs from the vessel weld (i.e. differs from the average for the weld wire heat number associated with the vessel weld and the surveillance weld), the measured values of Ll T 30 must be adjusted for differences in copper and nickel content by multiplying them by the ratio of the chemistry factor for the vessel material to that for the surveillance weld [2]. For cases in which the results from a credible plant-specific surveillance program are used, the value of (J to be used in the margin term of Equation (4) is 14°F for welds; this is called a reduced margin tehn. The value of (J need not exceed one-half of LlRT NDT [2]. The use of results from the plant-specific surveillance program method may result in a RT NDT that is higher or lower than that determined from the first ( chemistry table) method. If the resulting RTNDT from using the surveillance data gives a higher value it must be used. If the resulting RTNDT from using the surveillance data gives a lower value it may be used. NRC provided additional guidance for evaluation and use of surveillance data in Reference

| : 19. The guidance provides examples of Case 4 that may be used for evaluating the Palisades related surveillance data, as shown in Appendix B. Two cases are considered, Case 4a considers surveillance data from the plant of interest, and Case 4b for use of surveillance capsule data from both the plant of interest and also from its sister plants containing the same weld heat.

| |
| Also, if there is clear evidence that the copper or nickel content of the surveillance weld differs from that of the vessel weld, i.e., differs from the average of the weld wire heat number associated with the vessel weld and the surveillance weld, the measured values of i1RTNDT should be adjusted by multiplying them by the ratio of the chemistry factor of the vessel weld to that of the surveillance weld using the equation [19]: (9) According to the NRC guidance [19], further adjustment to the L1RT NDT data from other sources is needed if there is a difference between the capsule temperature from the other plant and the plant of interest.
| |
| A temperature correction of 1°F;oF is made to the i1RT NDT values to account for this difference; a positive temperature adjustment is made to capsules exposed to (time-weighted average) temperatures below the mean vessel temperature, and a negative temperature adjustment is made to capsules exposed to (time-weighted average) temperatures above the mean vessel temperature.
| |
| The mean vessel temperature for the Palisades vessel, using a time-weighted average for the plant operating cycles, is determined to be 535.2°F, as shown in Table 8. Guidance from Reference 19, Case 4, "Surveillance Data from Plant and Other Sources," and 10CFR50.61, method 2 for inclusion of plant-specific surveillance data, has been applied to evaluation of the W5214 surveillance data as described in Section 5.0. 4.0 DATA EVALUATION RESULTS In 1998, Consumers Energy provided a response to a Request for Information from NRC regarding pressure vessel integrity for the Palisades vessel [26]. That response evaluated seven surveillance capsules containing weld heat No. W5214 which were available at that time (two capsules from H. 13. Robinson 2, two capsules from Indian Point 2, and three capsules from Indian Point 3) and determined those data were not credible and, therefore, the data was not used to improve the projected RT pTs for the Palisades vessel. Since then, four more capsules containing this weld heat can be included in the analysis for use of surveillance data related to the Palisades limiting weld material.
| |
| An evaluation of these data starts with the original capsule reports. The new data survey was performed to gather all the unirradiated and irradiated capsule test results for the Palisades limiting weld material.
| |
| The data from all related surveillance capsules containing weld heat No. W5214 were compiled and the results were reviewed for applicability to the Palisades vessel weld. New data were discovered in the process of compiling these capsule reports. For example, there are two capsules from the Palisades supplemental Report No. 0901132.401, Rev. 0 6 Associates, Inc.
| |
| surveillance program that were previously unreported (References 14 -17). In addition, three capsules from the H. B. Robinson 2 surveillance program (References 12), two capsules from the Indian Point 2 surveillance program (References 6 -8), and four capsules from the Indian Point 3 surveillance program (References 9, 10, 11 and 13) were compiled and the Charpy V-notch test results were reviewed.
| |
| These reports include surveillance capsule fluences and comparisons between the unirradiated and irradiated Charpy V -notch curves to determine the L1RT NDT (or L1 T 30) shifts. The reported fluence values from these capsule reports, the average of measured surveillance weld copper and nickel chemistries, and the (measured and reported)
| |
| L1T30 shift results for these eleven capsules are shown in Table 1. The capsule reports are included in Appendix C (Palisades), Appendix D (Indian Point Unit 2), Appendix E (Indian Point Unit 3) and Appendix F (H. B. Robinson Unit 2). These are considered to be the reported data (or original data), with the exception of the Palisades capsule reports that were considered to be supplemental capsule test results. It is useful to fIrst combine these data without any adjustments for chemistry or irradiation temperature to determine the mean trend in irradiation damage behavior.
| |
| The mean trend, or average chemistry factor, can be calculated directly from a least squares fIt to the data using Equation (8). The least squares fIt method was used and a best fIt chemistry factor (CF) of 217.67°F was determined from these data, as shown in Table 1. The results are plotted in Figure 1 and are shown here for information only. The scatter in the measured -predicted results show that the scatter exceeds the 28°F (I-sigma) margin for two out of eleven points, but these two points are within the 56°F (2-sigma) margin. The average copper content for these surveillance materials is Cu = 0.243 wt%, and the average nickel content for these surveillance materials is Ni = 0.965 wt%. The predicted (average) chemistry factor for the surveillance specimens based on chemistry (from the PTS Rule Table 1) is CF = 234.37°F.
| |
| The mean fIt to the data shows that the CF value and the fItted trend for these data is well below that predicted by the PTS Rule method 1 (i.e., surveillance data not available).
| |
| 4.1 Original Re-evaluated Surveillance Capsule Fluence Westinghouse recalculated the capsule fluences from Palisades, Indian Point 2, Indian Point 3, and H. B. Robinson 2 using a consistent methodology to establish a common basis for the fluence values. This was an essential step so that all the surveillance capsule data could be evaluated properly for credibility and applicability to the Palisades vessel limiting weld material.
| |
| The revised fluence values for capsules containing weld heat No. W52I4 are shown in Table 2 [18]. It is noted that there were changes in the fluences from the originally calculated fluence values (shown in Table 1), and the new calculated fluence results (shown in Table 2) that were used to re-evaluate all the relevant surveillance data. The same Westinghouse fluence methodology was used to calculate fluence in the wall of the Palisades vessel for prediction of the vessel embrittlement.

| : 33. 4.3 Original and Re-evaluated Charpy V-notch Surveillance Data The surveillance capsule test results for weld heat No. W5214 from the Palisades supplemental capsules SA-60-1 and SA-240-1 are provided in Appendix C. The supplemental capsules with this weld heat were irradiated for a number of cycles, and removed and tested; capsule SA-60-1 was removed at the end of cycle 13, and capsule SA-240-1 was removed at the end of cycle 14. The specimens containing weld metal inserts were reconstituted to full size Charpy V -notch specimens.
| |
| The capsule materials were tested by Framatome in 2001 [14, 15]. The unirradiated Charpy energy values for the weld metals are documented in a letter from John R. Kneeland to Matthew J. DeVan dated February 2, 1999 [16]. The baseline (unirradiated) curve and weld metal chemistry data for these specimens are also provided in Appendix C. The surveillance capsule test results for weld heat No. W5214 from the Indian Point Unit 2 reactor surveillance capsule program are provided in Appendix D. The unirradiated data is contained in a Westinghouse report [8]. Southwest Research Institute tested two irradiated capsules, capsule Y [7] and capsule V [6]. The Indian Point 2 surveillance weld metal chemistry is also contained in these reports. There are four irradiated surveillance capsules containing weld heat No. W5214 and one baseline test report for the Indian Point Unit 3 plant, as shown in Appendix E. The baseline capsule report from Westinghouse contains the unirradiated data and one chemistry measurement for the surveillance weld [9]. The results for the four irradiated capsules are also given in one Westinghouse (WCAP-16251-NP) report [13]. This WCAP report contains the surveillance weld Charpy V-notch test results and measured chemistry data for the Indian Point Unit 3 plant. The surveillance capsule test results for weld heat No. W5214 from the H. B. Robinson Unit 2 reactor surveillance capsule program are provided in Appendix F. The unirradiated data is contained in a Westinghouse report [27]. There are three irradiated capsules from H. B. Robinson Unit 2 which contain weld heat No. W5214, capsule T, capsule V, and capsule X. The Charpy V-notch test results from these three capsules are contained in one Westinghouse (WCAP-15805) report [12]. This WCAP report also documents the measured surveillance weld chemistry for H.

| |
| [32]. The results presented here are considered to be "new data" because of the updated fluences and refitted values and because several additional capsules containing weld heat No. W5214 were uncovered in this survey that had not been previously evaluated together with the other data. The results from these new data were evaluated for applicability to the prediction of the RT PTS value for weld heat No. W5214 per 10CFR50.61

| 5.0 DATA CREDIBILITY ASSESSMENT AND FLUENCE EVALUATION The purpose of this evaluation is to apply the credibility requirements in 10CFR50.61 to the Palisades, H.B Robinson Unit 2, Indian Point Unit 2, and Indian Point Unit 3 surveillance capsule data and to determine if the surveillance capsule data is credible and can be used to improve the RTNDT predictions for the limiting vessel weld heat No. W5214. lOCFR50.61 describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of low-alloy steels currently used for light-water-cooled reactor vessels. lOCFR50.61 provides two methods for calculating the adjusted reference temperature of the reactor vessel beltline materials.
| |
| The first method is described in paragraph (c)(1). The second method is described in paragraphs (c)(2) and (c)(3). The procedures in paragraphs (c)(2) and (c)(3) can only be applied when two or more credible surveillance data sets become available.
| |
| These tests of surveillance data credibility are also stated in Section 3.3. NRC provided additional guidance for evaluation and use of surveillance data in Attachment 3 of Reference
| |
| : 19. The evaluation presented herein is organized like Case 4 from this guidance document, the case for plants with surveillance data for their plant and from other sources. 5.1 Credibility Evaluation:
| |
| Criterion 1: The materials in the surveillance capsules must be those which are the controlling materials with regard to radiation embrittlement.
| |
| The beltline region of the reactor vessel is defmed in Appendix G to 10 CFR 50, "Fracture Toughness Requirements" as follows: "the reactor vessel (shell material including welds, heat affected zones, and plates or forgings) that directly surrounds the effective height of the active core and adjacent regions of The reactor vessel that are predicted to experience sufficient neutron radiation damage to be considered in the selection of the most limiting material and regard to radiation damage." The Palisades reactor vessel consists of the following beltline region materials
| |
| [1, 31]: e Intermediate Shell, Axial Welds 2-112 AlBIC, material heat No. W5214, e Lower Shell, Axial Welds 3-112 AlBIC, material heat No. W5214 and 34B009, e Intermediate to Lower Shell, Circumferential Weld 9-112, material heat No. 27204, e Intermediate Shell, Plate D-3803-1, material heat No. C-1279, e Intermediate Shell, Plate D-3803-2, material heat No. A-0313, e Intermediate Shell, Plate D-3803-3, material heat No. C-I279, Report No. 0901132.401, Rev. 0 13 l::#rJI11'fillfi4i IntG.'nri:til Associates, Inc.

| 19 Lower Shell, Plate D-3804-1, material heat No. C-1308A, 19 Lower Shell, Plate D-3804-2, material heat No. C-1308B, 19 Lower Shell, Plate D-3804-3, material heat No. B-5294. The Palisades reactor vessel was designed and fabricated in accordance with the ASME Boiler and Pressure Vessel Code, Section III, 1965 Edition, including all addenda through Winter 1965 [21]. The Palisades reactor vessel surveillance program was originally developed with the intent to comply, where possible, with the guidance of ASTM EI85-66, "Recommended Practice for Surveillance Tests on Structural Materials in Nuclear Reactors" [22]. At the time that the Palisades surveillance capsules were built, 10 CFR50 Appendices G and H did not exist. 5.1.1 Description of Original Palisades Surveillance Capsule Program ASTM E 185-66 [22] describes the requirements for test specimens.
| |
| ASTM E 185-66 requires the base metal specimen be from " ... one heat with the highest initial ductile-brittle transition temperature", also known as the nil-ductility transition temperature (NDTT). Drop weight tests of Palisade's beltline samples identified five of the plates in contention for the highest initial NDTT at -30°F. The base material from shell plate D-3803-1 was selected over the other base metal specimens for the capsule base metal because it had the highest initial RT NDT temperature
| |
| [31]. ASTM E 185-66 requires a sample to represent one vessel weld if a weld occurs in the irradiated region. The original Palisades surveillance weld specimens were fabricated with the same procedure used to fabricate the reactor vessel axial welds, and were fabricated with a similar filler wire and fluxes as the reactor vessel beltline welds. However, the original Palisades surveillance capsules did not contain limiting axial weld heat No. W5214. 5.1.2 Description of Supplemental Surveillance Capsules SA-60-1 and SA-240-1 At the end of Cycle 11, the Palisades surveillance capsule program was augmented to contain two supplemental surveillance capsules, designated as SA-60-1 and SA-240-1, installed in the , capsule holders located on the core support barreL The new surveillance capsules, SA-60-1 and SA-240-1, included welds fabricated with weld wires of identical heats to those of the Palisades reactor vessel beltline welds. Surveillance capsule SA-60-1 and SA-240-1 contained test specimens from the following material heat No.'s: W5214, 34B009, 27204, and standard reference material HSST -02. All of these materials are the same heats as the materials used to fabricate portions of the reactor vessel that surround the active core and adjacent regions of the reactor vesseL Table 4 provides a tabulation of the specimens included in the Palisades supplemental surveillance capsules SA-60-1 and SA-240-1.

| * number of specimens in SA 1 capsule [15] Capsules SA-60-1 and SA-240-1 were removed from the Palisades reactor vessel at the end of cycles 13 and 14, respectively.
| |
| Twelve Charpy V-notch specimens made from weld heat No. WS214 were tested in capsule SA-60-1 [IS], and twelve Charpy specimens from heat No. WS214 were tested in capsule SA-240-1 [14]. Twelve Charpy V-notch specimens made from the HSST-02 correlation monitor material were tested from capsule SA-240-1 [14]. Because weld heat No. WS214 in the supplemental capsules matches the limiting axial welds, Criterion 1 is met for the Palisades reactor 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.
| |
| Criterion 2 is satisfied if the Charpy energy data for the surveillance capsules containing weld heat No. WS214 can be fitted to determine the 30 ft-lb temperature (T30) and upper shelf energy (USE) unambigudilsly.
| |
| An accurate determination of the 30 ft-Ib shift values is the reason these data were re-evaluated.
| |
| The TANH curve fit method provides an accurate and reproducible determination of these values and can be used to establish the T 30 and USE values for a given Charpy data set [24]. Unirradiated and irradiated Charpy energy versus temperature data for the weld metal were fitted and plotted using the CVGRAPH hyperbolic tangent curve fitting program [4]. The Charpy energy fitted results for the eleven surveillance capsules, including the calculated 30 ft-lb temperatures and upper shelf energy values, are shown in the Appendix G and summarized in Table 3. Based on engineering judgment by looking at the fitting parameters and the plots, the scatter in the data is small enough, and the correlation coefficients are high enough, to permit the determination of the 30 ft-lb temperature and upper shelf energy of the surveillance weld materials unambiguously.
| |
| Hence, Criterion 2 is met for all the surveillance capsules evaluated here which contain weld metal heat No. WS214. Report No. 0901132.401, Rev. 0 IS Stfltfctllrall!lIj.mrlhi Associates, Inc.
| |
| Criterion 3: When there are two or more sets of surveillance data from one reactor, the scatter of values about a best-fit line drawn as described in Position 2 (surveillance data available) normally should be less than 28°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 fails 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 in ASTM E185. The functional form of the least squares method as described in paragraph (c)(2) of 10CFR 50.61 will be utilized.
| |
| A best-fit line is generated for this data to determine if the scatter of the values about this line is less than 28°F for weld metal heat No. W5214. The Palisades limiting weld metal will be evaluated for credibility.
| |
| This weld is made from weld heat No. W5214. This weld metal is also contained in the Indian Point Unit 2, Indian Point Unit 3, and H. B. Robinson Unit 2 surveillance programs.
| |
| Since the welds in question utilized data from other surveillance programs, the recommended NRC methods for determining creditability will be followed.
| |
| Of the recommended methods, Case 4 most closely represents the situation listed above for the Palisades surveillance weld metal. Case 4a Credibility Assessment
| |
| -Palisades W5214 Data Only The data most representative for the Palisades limiting vessel weld are the supplemental surveillance capsules containing weld heat No. W5214 since the irradiation environment of the surveillance capsules and the reactor vessel are the same. The data requires the least adjustment.
| |
| An adjustment can be made for the difference between the chemistry of the capsule specimens (CF = 266.5°F) and the best estimate chemistry of the vessel (CF = 230.73°F) using the ratio procedure.
| |
| The updated fluence and ratio adjusted shift values were used to calculate a new least-squares fitted chemistry factor. The Palisades capsule data are shown in Table 5 along with the fitted solution (i.e., mean shift prediction) result, and the comparison of the predicted scatter from the fitted CF of 198.8°F. A plot of the measured vs. fluence results for the Palisades supplemental capsule weld (W5214) is shown in Figure 2 along with the +/-lcr bounds for credible data scatter. The data clearly fall within the I-sigma scatter band for credible surveillance data and the margin term can be reduced when using credible data. Based on criterion 3, the Palisades surveillance data is credible since the scatter is less than 28°F for both of these surveillance capsules.

| |
| -All W5214 Surveillance Capsule Data Following the guidance in Case 4 [19], the data from all sources should also be considered.
| |
| For weld heat No. W5214 there are a total of eleven surveillance capsules from Palisades, Indian Point Unit 2, Indian Point Unit 3, and H.B. Robinson Unit 2. Since data are from multiple sources, the data must be adjusted first for chemical composition differences and then fbr irradiation temperature differences before determining the least-squares fit. For a credibility determination, the measured and refitted T30 shift data for all the relevant plant data was normalized to the mean chemistry factor of the vessel (230.73°F) using the ratio procedure and then to the mean operating temperature (535.2°F) for the Palisades vessel (see Table H-7). The fitted CF value, shown in Table 6, is determined to be 227.74°F for this case. The results for (measured
| |
| -predicted) scatter for all the W5214 surveillance data results are shown in Table 7. The results for all the surveillance capsule data are plotted in Figure 3 along with the +/-2cr scatter bands. The scatter in the measured -predicted values exceeds 28°F (1-sigma) for a few points. Four of the measured -predicted LlRTNDT values are outside the I-sigma hand of 28°F, but all data points are within the 56°F (2-sigma) scatter band for welds. According to 10CFR50.61 paragraph (c)(2)(iv), the use of results from the plant-specific surveillance program may result in an RTNDT that is higher or lower than that determined from the chemistry of the weld and a chemistry factor using the tables. If the CF value is higher, it must be used for RT PTS predictions, if the CF value is lower, it may be used. The chemistry factor from paragraph (c)(1) is 230.73°F, and the adjusted chemistry factor using the Palisades surveillance capsule data is 227.74°F.
| |
| It is noted that per NRC guidance that it is possible to use a lower value of chemistry factor based upon all sources of surveillance capsule data with a full margin term (i.e., 56°F) if the data is credible in all other ways but the scatter. In summary, the (measured
| |
| -predicted) scatter for all the W5214 weld data is within the acceptable range of 56°F for a wide range of fluence. For this case, the surveillance capsule fluence ranges between 2.63xlO 18 n/cm 2 to 4.49xlO 19 n/cm 2. Therefore, the weld data meets this criterion, and the Palisades surveillance program weld metal chemistry factor to be used for determining RT pTs and RTNDT is 227.74°F in combination with a full (2-sigma) margin term.

| The location of the specimens with respect to the reactor vessel beltline assured that the reactor vessel wall and the specimens have experienced equivalent operating conditions such that the temperatures did not differ by more than 2S0F. Therefore, this criterion is satisfied for the Palisades capsules.

| |
| 5.2 Palisades Vessel Fluence Evaluation Fluence in the Palisades vessel beltline has been tracked to manage the PTS issue. The fluence projections are important to be able to predict the future levels of embrittlement in the vessel beltline materials.
| |
| Calculations of the neutron exposure of the Palisades reactor pressure vessel were previously completed and documented in WCAP-I5353, Revision 0 [3]. That evaluation, along with the benchmarking method, was submitted for review by the NRC Staff and the methodology and the final results were approved as part of the PTS evaluation in 2000 [1]. The previous evaluation determined that the peak fluence at the clad-to-base-metal interface at the 60° limiting axial weld was 1. 158xl0 19 n1cm 2 (E > 1 MeV) at the end of Cycle 14 (i.e., October 1999) [34]. Since then, ten more years of plant operation has occurred and, as a result, the vessel has accumulated additional fluence. Recently, Westinghouse provided an updated fluence assessment for the Palisades vessel beltline region that includes cycle specific analysis for additional operating cycles for which the design has been finalized and operations are known (Cycles 15 through 21) and projections for future operation based on the best available knowledge as a function ofEFPY and estimated calendar dates [18]. The calculated and projected neutron fluence values for the limiting 60° weld location are given in Table 11. Note: the cycle specific projections for the designs of Cycles 21 and beyond were provided by Entergy and include an assumed load factor of95% for future plant operation

The refitted Charpy data results have been incorporated along with updates to the average capsule irradiation temperatures, corrections to account for chemistry differences, and results of the revised fluence calculations for the capsules and for the Palisades vessel have been included.
| |
| Four cases are considered for prediction of the date to reach the PTS screening criteria limit. The first case is Position 1 of the PTS Rule using the current licensing basis method and considering the revised fluence calculations and projections, as shown in Table 11. The chemistry factor for the weld heat No. W5214 was based on best-estimate Cu = .213%, Ni = 1.01 %, and a CF = 231.08°F.
| |
| The maximum fluence limit was calculated to be 1.584xl0 19 nlcm 2 according to the embrittlement prediction method when surveillance data is not available.
| |
| That prediction ofRT NDT shift is shown in Table 12, and the corresponding date to reach the PTS screening criteria limit of 270°F for axial welds is March 2014 using the fluence interpolation given in Table 16. The current licensing basis date to reach the PTS screening criteria date is Report No. 0901132.401, Rev. 0 23 StrJ'mtlm'lllntlt.'firi:fll Associates, Inc.
| |
| January 2014 as given in Reference
| |
| : 1. It has been determined that the Palisades plant is still operating within that licensing basis. The second case follows Position 1 of the PTS Rule but considers that the actual best-estimate chemistry for weld heat No. W5214 has slightly lower nickel as determined by the CEOG report in 1998 [20]. This evaluation was performed after the initial PTS submittal in 1995 and, using this information, the revised Ni = 1.007% which gives a new value ofCP = 230.73°P.
| |
| It is permitted under the PTS Rule in 10CPR50.61 to use the best-estimate values for Cu and Ni, however there is only a slight difference in the maximum fluence to reach the PTS screening criteria limit (i.e., 1.595xl0 19 nlcm 2) as shown in Table 13. The projected date to reach that limit using the interpolated fluence projections is July 2014 as shown in Table 16. Although this case does not show much additional margin from the January 2014 date, it is provided here to show that there is still slightly more time to be gained within the Position 1 approach of the PTS Rule method before the vessel reaches the 270 0 P screening criteria limit. The third case considered plant-specific surveillance data from the Palisades supplemental capsules containing weld heat No. W5214. This case is labeled as Case 4a per the guidance document for use of surveillance data [19]. The Case 4a credibility assessment calculated a fitted chemistry factor of 198.8°P from the two Palisades capsule data points., The data were deemed to be credible based on meeting all the credibility criteria including scatter within the I-sigma (i.e., 28°P) scatter bounds. The limiting fluence for the vessel for this case is shown in Table 14. Using these results and a reduced margin term to account for credible data, the projected date to reach the PTS screening criteria limit would be beyond 2034 for the limiting vessel weld heat No. W5214, as shown in Table 18. Note: It is likely that some other beltline material would become limiting if this case was used for weld heat No. W5214. However, this case demonstrates that surveillance data can provide significant improvement in determining the effects of embrittlement on the limiting vessel beltline weld material.
| |
| The fourth case, pe:l:1nitted under the PTS Rule, is to use all sources of surveillance data that match the limiting weld heat No. W5214. This is designated as Case 4b, and the credibility assessment determined the fitted CP = 227.74°P.
| |
| The data meet credibility criteria 1,2,4, & 5, and the scatter of the (measured
| |
| -predicted) data was within 2-sigma (i.e., 56°P) such that it can be considered to be credible data for the chemistry factor, however the margin term, (J 11, cannot be reduced in half. Use of Case 4b for the Palisades vessel is acceptable because the (measured
| |
| -predicted) scatter in the weld data is within the acceptable range of 56°P for a wide range of fluence. The limiting fluence for Case 4b is 1.685xl0 19 nlcm 2 (E > 1 MeV) as shown in Table 15. Table 17 interpolates the vessel fluence and shows the projected date to reach the screening criteria limit is April 2017, a difference of three years compared to the first case using the current licensing basis and Position 1 approach.

| ==SUMMARY==
| |
| AND CONCLUSIONS The results for all a v ailable surveillance capsules containing weld heat No. W5214 ha v e been evaluated for applicability to the Palisades limiting vessel weld. Updates to the surveillance capsule fluences and the projected fluence in the Palisades v essel were also reviewed and included in these analyses.
| |
| The methods of 10CFR50.61 were applied including options for considering the effects of surveillance data on the projected RT NDT values. Using Position 1 of the PTS Rule (without the use of surveillance data) shows a projected date to reach the PTS screening criteria limit as late as July 2014. Ho w ever, use of the weld heat No. W214 surveillance data can improve the projections of embrittlement and significantly changes the date to reach the screening criteria limit. Since weld heat no. W5214 is currently identified as the limiting material, the projections using Case 4a with the credible Palisades supplemental surveillance data show that the PTS screening criteria limit of 270°F would not be reached until after 2034; however , other vessel beltline materials would become limiting and that would change that date. For Case 4b, the surveillance data for weld heat No. W5214 were shown to be credible for determination of the CF value , but the scatter in the data would not permit a reduction in the margin term. Howe v er , use of the *fitted chemistry factor for Case 4b with the revised fluence projections and the full margin term provides a better determination of the vessel embrittlement prediction for the limiting vessel weld. Using all the a v ailable weld heat No. W5214 surveillance data, a CF value of 227.74°F was determined for Case 4b and a projected date to reach the screening criteria limit of approximately April 2017 was estimated using the updated fluence proje c tions from Westinghouse.

Box 10935 Lynchburg, Virginia 24506-0935 BAW-2398 May 2001 fRAMATOME AHP Executive Summary This report describes the results of the tests performed on the specimens contained in the second supplemental reactor vessel surveillance capsule (Capsule SA-240-1) from the Consumers Energy Palisades Nuclear Plant. The objective of the program is to mom tor the effects of neutron irradiation on the mechanical properties of the reactor vessel materials by testing and evaluation of Charpy impact specimens.
| |
| Supplemental Capsule SA-240-1 was removed from the Palisades reactor vessel at the cycle 14 (EOC-14) for testing and evaluation.
| |
| The test specimens included modified 18mm Charpy V-notch inserts for three weld metals fabricated with weld wire heats W5214, 34B009, and 27204 and standard Charpy V -notch specimens fabricated from the correlation monitor plate material, HSST Plate 02. The weld metal Charpy inserts were reconstituted to full size Charpy V-notch specimens.
| |
| The reconstituted weld metals along with HSST Plate 02 material were Charpy*impact tested. The results of these tests are presented in this document.

| |
| : 1. Observation of the Capsule SA-240-1 thermal monitors indicated that the irradiated test specimens were exposed to a maximum irradiation temperature less than 558°P. 2. Thirty-six pre-machined irradiated 18mm Charpy inserts were successfully reconstituted and machined to Type A Charpy impact specimens.
| |
| The reconstituted Charpy specimens were subsequently impact tested. 3. The 30 ft-lb and 50 ft-Ib transition temperatures for the weld metal W5214 increased 280.1 °P and 390.1 °P, respectively.
| |
| In addition, the CvUSE for this material decreased 48.9%. 4. The 30 fr-lb and 50 ft-Ib transition temperatures for the weld metal 34B009 increased 259.4°P and 325.8°P, respectively.
| |
| In addition, the CyUSE for this material decreased 49.6%. 5. The 30 ft-lb and 50 ft-Ib transition temperatures for the weld metal 27204 increased 267 .8°P and 399.7°P, respectively.
| |
| In addition, the CvUSE for this material decreased 50.4%. 6. The correlation monitor plate demonstrated similar behavior with an increase in the 30 ft-Ib and 50 ft-Ib transition temperatures of 140.9°P and 145.9°P, respectively.
| |
| The percent decrease in the CvUSE for this material is 29.8%. 6-1 ERAMATOME ANP J o o o TJ L.

Box 10935 Lynchburg, Virginia 24506-0935 FRAMATOME ANP f\ U o u o o D o D o o tJ o o [J D Executive Summary This report describes the results of the test specimens from the first supplemental capsule (Capsule SA-60-1) of the Consumers Energy Palisades Nuclear Plant as part of their reactor vessel surveillance program. The objective of the program is to monitor the effects of neutron irradiation on the mechanical properties of the reactor vessel materials by testing and evaluation of Charpy impact specimens.
| |
| Supplemental Capsule SA-60-1 was removed from the Palisades reactor vessel at the cycle 13 (EOC-13) for testing and evaluation.
| |
| The capsule contents were removed from Capsule SA-60-1 for testing and examination.
| |
| The test specimeps included modified 18mm Charpy notch inserts for three weld metals fabricated with weld wire heats W5214, 34B009, and 27204 and standard Charpy V -notch specimens fabricated from the correlation monitor plate material, HSST Plate 02. The weld metal Charpy inserts were reconstituted to full size Charpy V-notch specimens.
| |
| The reconstituted weld metals along with HSST Plate 02 material were Charpy impact tested. Following the initial Charpy V-notch impact testing, the laboratory perfonned-a calibration of the temperature indicator used in the Palisades Capsule SA-60-1 testing. The results of the laboratory calibration indicated the instrument was out-of-tolerance.
| |
| Based on the results of this calibration test, the laboratory revised the Charpy impact test temperatures accordingly.
| |
| Revision 1 corrects the test temperatures for the Supplemental Capsule SA-60-1 reconstituted weld metal Charpy V-notch impact specimens and the HSST Plate 02 Charpy V-notch impact specimens.
| |
| Revision 2 provides an update to the hyperbolic tangent.curve fits of the Charpy impact curves by restraining the upper-shelf energy. For these curve fits, the lower-shelf energy was fixed at 2.2 ft-Ibs for all cases, and for each materials the upper-shelf energy was fixed at the average of all test energies exhibiting 100% shear, consistent with ASTM Standard E 185-82. ii FRAMATOME ANP 2 r] LJ [J [J o o [1 o J o [] II u u o u q L. o Table 3-2.

| E. Landerman Westinghouse Electric Corporation Nuclear Energy Systems Division Box 355 Pittsburgh, Pa. 15230 SECTION 4 POST-IRRADIATION TESTING Specimen capsules will be removed from the reactor only during normal refueling periods. The recommended scbedule for removal of capsules is as follows: Capsule Capsule Type Identification Exposure Time I T (Replacement of 1st Region) II S (Replacement of 2nd Region) I Z (Replacement of 4th Region) II V 10 years I U I I W Extra capsules for complementary I X testing or additional exposure II Y Each specimen capsule upon removal after radiation exposure will be ferred to a post-irradiation test facility for disassembly of the capsule and testing of all specimens.
| |
| 4.1 CHARPY V-NOTCH IMPACT TESTS The testing of the eight Charpy impact specimens from each of the IPP vessel plates, the weld and HAZ metal, and the correlation monitor material in the capsules can be -done singulary, possible the performanGe of Charpy imp.act tests at five different temperatures, with three extra specimens to provide an optimum curve for each plate. Tbe initial Charpy specimen from the first capsule removed shpu1d be tested at room temperature.
| |
| The impact energy value for this te$t temperature should be compared with irradiation test data. The testing temperatures for the remaining specimen should then be appropriately raised or lowered. The test temperatures of 9 7 specimens from capsules exposed to longer irradiation periods should be determined by the test results for the previous capsule. 4.2 TENSILE TESTS The two tensile specimens per plate or weld from each of the capsules should be tested at room temperature and the approximate operating temperature of the reactor (550 0 P). 4.3 WEDGE OPENING LOADING TESTS The WOL specimens from each individual capsule should be tested at a ature based on the transition temperature shift obtained from the associated Charpy impact specimens.
| |
| fA. mean temperatur.e of -200 "'F plus the transition temperature shift should be the initial test temperature.
| |
| 4.4 POST-IRRADIATION TEST EQUIPMENT
| |
| : 1. Milling machine or special wheel for capsules and dosimeter blocks. 2. Hot-cell tensile testing machine with: a. pin-type adapter for pulling tensile tests b. clevis and extensometer for pulling WOL specimens.

REACTOR VESSEL MATERIAL SURVEILLANCE PROGRAM FOR lNDIAN POINT UNIT NO.2 ANALYSIS OF CAPSULE V FINAL REPORT SwRI Project No. 17*2108 Prepared for Consolidated Edison Company of New York, Inc. 4 Irving Place New York, New York 10003 October 1988 Approved by B.

| * I ,'. , . i ' t.". ( "', U ; '-..-' \i u '-:, l SUlIlMARY OF RESULTS AND CONCLUSIONS The analysis of the fourth material smveillance capsule removed from the Indian Point Unit No. 2 reactor pressure vessel led to the following conclusions:
| |
| (1) Based on a. calculated neutron spectral distribution, Capsule V received a fast fiuence of . -5.3.x 10 18 n/em 2 (E > 1 MeV) at its radial center line, (2) The surveillance specimens of the core beltline plate materials experienced shifts in RTNDT (50 ft-Ib. values) over the range of *79°F (Plate B2002*2) to 239°F (Weld) as a result of fast neutron exposure up to the 1987 refueling outage. (3) The core beltline weld exhibited the largest shift in RTNDT and is projected to control the heatup and cooldown limitations throughout the 'design lifetime of the pressure vessel. (4) . From the previous capsule, Z, the estimated maximum neutron fiuence of 3.33 x lOIS'" neutrons/cm 2 (E > 1 MeV) was received by the vessel wall in 5.17 effective full power years (EFPY) through Cycle 5, which is equal to a fiuence rate of 6.44 x 10 17'" per EFPY. At the end of Cycle 8 (8.6 EFPY) the neutron fiuence was 4.45 .x 10 18 n/cm 2 giving 3.26 x lOF n/cm 2 per ErFY for Cycles 6 through 8. This calculated value for the decrease in fiuence per EFPY agrees well with the experimental value for the decrease in fiuence rate; i.e., 50.6% vs. 48.9%. The use of a low leakage core loading pattern beginning with Cycle 6 did significantly reduce the fIuence rate on the pressure vessel wall. $Revised from Capsule Z report using the la.test plant specific lea.d factors. 1-1

| ==SUMMARY==
| |
| OF RESULTS The analysis of the reactor vessel materials contained in surveillance Capsule X, the fourth capsule removed and tested from the Indian Point Unit 3 reactor pressure vessel, led to the following conclusions:
| |
| I) The Charpy V-notch data presented in WCAP-8475[31, WCAP-9491
| |
| [4], WCAP-] 0300[5], and WCAP-J 1815[6] were based on hand-fit Charpy curves using engineering judgment.
| |
| However, the results presented in this report are based on a re-plot of all applicable capsule data using CVGRAPH, Version 5.0.2, which is a byperbolic tangent curve-fitting program. Appendix C presents the CVGRAPH, Version 5.02, Charpy V-notch plots and the program input data. Capsule X received an average fast neutron fluence (E> 1.0 MeV) of 0.874 x 10 19 n/cm" after 15.5 effective full power years (EFPY) of plant operation.
| |
| Irradiation of the reactor vessel lower shell plate B2803-3 Charpy specimens, oriented with the longitudinal axis oftbe specimen parallel to tbe major working direction (longitudinal orientation), resulted in an irradiated 30 ft-Ib transition temperature of 191.6°F and an irradiated 50*ft-Ib transition temperature of 223. 8°F. This results in a 30 ft-lb transition temperature increase of 159.6°F and a 50 ft-Ib transition temperature increase of 1 61.7°F for the longitudinal oriented specimens.
| |
| See Table 5-9. Irradiation of the reactor vessel lower shell plate B2803-3 Charpy specimens, oriented with the longitudinal axis ofthe specimen perpendicular to the major working direction (transverse orientation), resulted in an irradiated 30 ft-Ib transition temperature of216.5°F and an ilTadiated 50 ft-Ib transition temperature of 327.4°F. This results in a 30 ft-Ib transition temperature increase of 158.2°F and a 50 ft-lb transition temperature increase of2l7.9°F for the longitudinal oriented specimens.
| |
| See Table 5-9. Irradiation of the weld metal (heat number W52J4) Charpy specimens resulted in an irradiated 30 ft-Ib transition temperature of 128.5°F and an irradiated 50 ft-Ib transition temperature of 196.8°F. This results in a 30 ft-Ib transition temperature increase of 193.2°F and a 50 ft-Ib transition temperature increase of 242.8°F. See Table 5-9. Irradiation of the reactor vessel intermediate shell plate B2802-2 Charpy specimens, oriented with the longitudinal axis ofthe specimen parallel to the major working direction (longitudinal orientation), resulted in an irradiated 30 ft-lb transition temperature of 98.1 OF and an irradiated 50 ft-lb transition temperature of 145.0°F. This results in a 30 ft-Ib transition temperature increase of 152.6°F and a 50 ft-lb transition temperature increase of 166.5°F for the longitudinal oriented specimens.
| |
| See Table 5-9. The average upper shelf energy of the lower shell plate B2803-3 (longitudinal orientation) resulted in an average energy decrease of 24 ft-lb after irradiation.
| |
| This results in an irradiated average upper shelf energy of 81 ft-Ib for the longitudinal oriented specimens.
| |
| See Table 5-9. Summary of Results 1-2 The average upper shelf energy of the lower shell plate B2803-3 (transverse orientation) resulted in an average energy decrease of 16 ft-lb after irradiation.
| |
| This results in an irradiated average upper shelf energy of 52 ft-Ib for the longitudinal oriented specimens.
| |
| See Table 5-9. The average upper shelf energy of the weld metal Charpy specimens resulted in an average energy decrease of 46 ft-lb after irradiation.
| |
| This results in an irradiated average upper shelf energy of 74 ft-Ib for the weld metal specimens.
| |
| See Table 5-9. The average upper shelf energy of the intermediate shell plate B2802-2 (longitudinal orientation) resulted in an average energy decrease of 20 ft-Jb after irradiation.
| |
| This results in an irradiated average upper shelf energy of 105 ft-Ib for the longitudinal oriented specimens.
| |
| See Table 5-9. A comparison, as presented in Table 5-10, of the Indian Point Unit 3 reactor vessel surveillance material test results with the Regulatory Guide 1.99, Revision 2 fJ] predictions led to the following conclusions:
| |
| The measured 30 ft-lb s}rift in transition temperature values of the lower shell plate B2803-3 contained in capsule X (longitudinal
| |
| & transverse) are greater than the Regulatory Guide 1.99, Revision 2, predictions.
| |
| However, each shift value is less than the two sigma allowance by Regulatory Guide 1.99, Revision 2. The measured 30 ft-lb shift in transition temperature value of the weld metal contained in capsule X is less than the Regulatory Guide 1.99, Revision 2, prediction.
| |
| The measured 30 ft-lb shift in transition temperature values of the intermediate shell plate B2802-2 contained in capsule X (longitudinal) is greater than the Regulatory Guide 1.99, Revision 2, prediction.
| |
| However, the shift value is Jess than the two sigma allowance by Regulatory Guide 1.99, Revision 2. The measured percent decrease in upper shelf energy for all the surveillance materials of Capsules X contained in the Indian Point Unit 3 surveillance program are in good agreement with the Regulatory Guide 1.99, Revision 2 predictions.
| |
| All beltline materials exhibit a more than adequate upper shelf energy level for continued safe plant operation and are predicted to maintain an upper shelf energy greater than 50 ft-lb throughout the life ofthevessel (27.1 EFPy) as required by I OCFR50, Appendix G [2]. SUlmnary of Results 2 INTRODUCTION This repOli presents the results of the examination of Capsule X, the fourth capsule removed from the reactor in the continuing surveillance program which monitors the effects of neutron irradiation on the hldian Point Unit 3 reactor pressure vessel materials under actual operating conditions.
| |
| 2-1 The surveillance program for the Indian Point Unit 3 reactor pressure vessel materials was designed and recommended by the Westinghouse Electric Corporation.
| |
| A description of the surveillance program and the pre-irradiation mechanical properties ofthe reactor vessel materials are presented in WCAP-8475, "Consolidated Edison Co. of New York Indian Point Unit No.3 Reactor Vessel Radiation Surveillance Program,,[3
| |
| : 1. The surveillance program was planned to cover the 40-year design life of the reactor pressure vessel and was based on ASTM E185-62, "RecOlmnended Practice for Surveillance Tests on Structural Materials for Nuclear Reactors." Capsule X was removed from the reactor after 15.5 EFPY of exposure and shipped to the Westinghouse Science and Technology Department Hot Cell Facility, where the irradiation mechanical testing of the Charpy V-notch impact and tensile surveillance specimens was performed.
| |
| This report summarizes the testing of and the post-irradiation data obtained from surveillance capsule X removed from the Indian Point Unit 3 reactor vessel and discusses the analysis of the data.

| ==SUMMARY==
| |
| OF RESULTS The analysis of the reactor vessel materials contained in surveillance capsule X the fourth capsule to be removed from the H.B, Robinson Unit 2 reactor pressure vessel, led to the following conclusions: (General Note: Temperatures are reported to two significant digits only to match CVGraph output.) 1-1 e The capsule received an average fast neutron calculated fluence (E> 1.0 MeV) of 4.49 x 10 19 nlcm 2 after 20.39 effective full power years (EFPy) of plant operation.
| |
| Irradiation of the reactor vessel intermediate shell plate WI0201-4 Charpy specimens, oriented with the longitudinal axis of the specimen parallel to the major working direction of the plate (longitudinal orientation), to 4.49 x 10 19 nlcm 2 (E> 1.0MeV) resulted in a 30 ft-Ib transition temperature increase of 104. 73°P and a 50 ft-Ib transition temperature increase of98.68°P.
| |
| This results in an irradiated 30 ft-Ib transition temperature of 86.55°P and an irradiated 50 ft-lb transition temperature of 116.04°P for the longitudinally oriented specimens Irradiation of the weld metal Charpy specimens to 4.49 x 10 19 n/cm 2 (E> l.OMeV) resulted in a 30 ft-lb transition temperature increase of 265.93°P and a 50 ft-lb transition temperature increase of 251. 74°P. This results in an irradiated 30 ft-Ib transition temperature of 179.64°P and an irradiated 50 ft-lb transition temperature of 211.38°F.
| |
| Irradiation of the weld Heat-Affected-Zone (HAZ) metal Charpy specimens to 4.49 x 10 19 nlcm 2 (E > 1.0 MeV) resulted in a 30 ft-Ib transition temperature increase of 210. I3 0 P and a 50 ft*lb transition temperature increase of216.59°P.
| |
| This results in an irradiated 30 ft-lb transition temperature of l00.47°F and an irradiated 50 ft-Ib transition temperature of 150.54°P.
| |
| Irradiation of the correlation monitor material Charpy specimens to 4.49 x 10 19 nlcm 2 (E > 1.0 MeV) resulted in a 30 ft-Ib transition temperature increase of 125.21 OF which resulted in an irradiated 30 ft-lb transition temperature of 188.1SoP.
| |
| The tested specimens did not reach the 50 ft-Ib transition temperature.
| |
| The average upper shelf energy ofllie intermediate shell plate WI0201-4 (longitudinal orientation) resulted in an average energy decrease of 1 flAb after irradiation to 4.49 x 10 19 n/cm 2 (E> 1.0 MeV). This results in an irradiated average upper shelf energy of 94 ft-lb for the longitudinally oriented specimens.
| |
| The average upper shelf energy of the weld metal Charpy specimens resulted in an average energy decrease of 33 ft-Ib after irradiation to 4.49 x 10 19 nlcm 2 (E> 1.0 MeV). Hence, this results in an irradiated average upper shelf energy of 80 ft-lb for the weld metal specimens.
| |
| The average upper shelf energy of the weld HAl metal Charpy specimens resulted in an average energy decrease of 24 ft-lb after irradiation to 4.49 x 10 19 nlcm 2 (E> 1,0 MeV). Hence, this results in an irradiated average upper shelf energy of 105 ft-lb for the weld HAZ metal.

| Robinson Unit 2 Capsule X 5-3 5.2 CHARPY V-NOTCH IMPACT TEST RESULTS The results of the Charpy V -notch impact tests performed on the various materials contained in capsule X, which received a fluence of 4.49 x 10 19 nlcm 2 (E > 1.0 MeV) in 20.39 EFPY of operation, are presented in Tables 5-1 through 5-8, and are compared with unirradiated results as shown in Figures 5*1 through 5-12. The transition temperature increases and upper shelf energy decreases for the capsule X materials are summarized in Table 5-9. These results led to the following conclusions:
| |
| Irradiation of the reactor vessel intermediate shell plate WI 020 1-4 Charpy specimens, oriented with the longitudinal axis of the specimen parallel to the major working direction of the plate (longitudinal orientation), to 4.49 x 10 19 nJcm 2 (E> l.OMeV) resulted in a 30 ft-Ib transition temperature increase of 104.73°F and a 50 ft-Ib transition temperature increase of 98.68°F. This results in an irradiated 30 ft-Ib transition temperature of 86.55°F and an irradiated 50 ft-Jb transition temperature of 1 16.04°F for the longitudinally oriented specimens Irradiation of the weld metal Charpy specimens to 4.49 x 10 19 nJcm 2 (E> l.OMeV) resulted in a 30 ft-Ib transition temperature increase of265.93°F and a 50 ft-Ib transition temperature increase of 251.74°F.
| |
| This results in an irradiated 30 ft*lb transition temperature of 179.64°F and an irradiated 50 ft-Ib transition temperature of211.38°F.
| |
| Irradiation of the weld Heat-Mected-Zone (HAZ) metal Charpy specimens to 4.49 x 10 19 n/cm 2 (E > 1.0 MeV) resulted in a 30 ft-Ib transition temperature increase of210.13°F and a 50 ft-lb transition temperature increase of 216.59°F.
| |
| This results in an irradiated 30 ft-Ib transition temperature of . 100.47°F and an irradiated 50 ft-Ib transition temperature of 150.54°F.
| |
| Irradiation of the correlation monitor material Charpy specimens to 4.49 x 10 19 n/cm 2 (E > 1.0 MeV) resulted in a 30 ft-lb transition temperature increase of 125.21 OF which resulted in an irradiated 30 ft-Ib transition temperature of 188 .1soF. The tested specimens did not reach the 50 ft-Ib transition temperature.
| |
| The average upper shelf energy of the intermediate shell plate WI 020 1-4 (longitudinal orientation) resulted in an average energy decrease of 1 ft-Ib after irradiation to 4.49 x 10 19 n/cm 2 (E> 1.0 MeV). This results in an irradiated average upper shelf energy of94 ft-Ib for the longitudinally oriented specimens.
| |
| The average upper shelf energy of tlie weld metaJ Charpy specimens resulted in an average energy decrease of 33 ft-lb after irradiation to 4.49 x 10 19 n/cm 2 (E> 1.0 MeV). Hence, this results in an irradiated average upper shelf energy of 80 ft-Ib for the weld metal specimens.
| |
| The average upper shelf energy of the weld HAZ metal Charpy specimens resulted in an average energy decrease of 24 ft-lb after irradiation to 4.49 x 10 19 n/cm 2 (E > 1.0 MeV). Hence, this results in an irradiated average upper shelf energy of 105 ft-Ib for the weld HAZ metal. The average upper shelf energy of the correlation monitor material Charpy specimens resulted in no energy decrease after irradiation to 4.49 x 10 J9 n/cm 2 (E> 1.0 MeV). Hence, this results in an irradiated average upper shelf energy of 42 ft-Ib for the correlation monitor material.
| |
| Analysis ofH.B. Robinson Unit 2 Capsule X 5-4 A comparison of the H.B. Robinson Unit 2 reactor vessel beltline material test results with the Regulatory Guide 1.99, Revision i!J, predictions led to the following conclusions:
| |
| The measured 30 ft-Ib shift in transition temperature values of the intermediate shell plate Wi 0201-4 contained in capsule X (longitudinal) is greater than the Regulatory Guide 1.99, Revision 2, predictions.
| |
| However, the shift value is less than two sigma allowance by Regulatory Guide 1.99, Revision 2. The measured 30 ft*lb shift in transition temperature values of the weld metal contained in capsule X (longitudinal) is less than the Regulatory Guide 1.99, Revision 2, predictions.
| |
| The measured percent decrease in upper shelf energy of the Capsule X surveillance material is less than the Regulatory Gtride 1.99, Revision 2, predictions.
| |
| The fracture appearance of each irradiated Charpy specimen from the various surveillance capsule X materials is shown in Figw-es 5-13 through 5-16 and show an increasingly ductile or tougher appearance with increasing test temperature.
| |
| The load-time records for individual instrumented Charpy specimen tests are shown in Appendix A The Charpy V -notch data presented in this report is based on a re-plot of all capsule data using CVGRAPH, Version 4.1, which is a hyperbolic tangent curve-fitting program. Hence, Appendix C contains a comparison of the Charpy V-notch shift results for each surveillance material (hand-fitting versus hyperbolic tangent curve-fitting).

(e) If further material data is desired, then it is reconunended that these capsules be moved to a higher lead factor location and then removed once their accumulated neutron fluence equals the license renewal (50 EFPy) fluence on the vessel inner surface. (f) Moved to Capsule "S" Location (280°) at Cycle 8, eg) Capsule Z was inadvertently removed from the H.B. Robinson 2 Reactor VesseL At this time jt is unconfumed that Capsule Z was re-installed into the vessel or placed in the spent fuel pool.

| Calculation of Time-weighted Average Temperatures for Surveillance Capsules Containing Weld Heat No. W5214 The irradiation temperatures for the various surveillance capsules have been reviewed and verified in support of the credibility analysis for all sources ofW52l4 weld metal [33]. The Palisades time-weighted average capsule and vessel temperatures were determined from plant operating history data [23]. The weighted average temperatures considered that the capsules were inserted for only two and three cycles. The resulting time weighted temperature for capsule SA-60-1 and SA-240-1 is 535.0°F and 535.7°, respectively, as determined from the values shown in Table 8. The vessel time-weighted average temperature is determined to be 535.2°F, as shown in Table H-7. Discussions with staff at H. B. Robinson 2 indicate that the values for irradiation temperature ofHB2 T, HB2 V, and HB2 X are 547°F, which is consistent with the temperature values, listed in Table D-5 ofWCAP-15085
| |
| [12]. Cycle by cycle Tcold temperatures were reviewed for Indian Point Unit 2 and Indian Point Unit 3 in order to generate time weighted temperatures corresponding to each of the surveillance capsules which contain W5214 weld metal. For Indian Point Unit 2 the data was reviewed from Calculation Number FCX-00538
| |
| [29]. For Indian Point Unit 3 the data was reviewed from Calculation Number IP3-CALC-RV-03720
| |
| [30]. The radiation exposure and temperature history ofIndian Point Unit 2 relative to Capsule Y and Capsules V is shown below.

| Listing of Design Inputs for Weld Heat No. W5214 Surveillance Data Re-evaluation A roadrnap to the references used in this report is provided in this Appendix.
| |
| This roadmap provides a snapshot of the various references used to obtain the design inputs for chemistry factor, unirradiated and irradiated Charpy V-notch (CVN) data, the TANH methodology used to fit the CVN data, capsule fluences, the regulatory guidance documents and codes used, and the inputs used for the estimation of the time weighted average temperatures for the various surveillance capsules.
| |
| It is to be noted that several of the inputs used in this report have been superseded by more recent reports based on the availability of new data (such as re-evaluation of capsule reports and updated fluence calculations).
| |
| The measured chemistries for the surveillance capsule materials were obtained from the respective surveillance capsule reports that contain the weld heat No. W5214. Fhience data that were historically used in previous reports and submittals were also obtained from the respective capsule reports. More recent fluence values for the surveillance capsules were obtained from an updated fluence calculation by Westinghouse
| |
| [18]. It is to be noted that even though the design inputs used in this capsule re-evaluation may be available in more than one source, the roadmap points to specific references in order to use the most current and valid inputs in the analysis.

U.S. Nuclear Regulatory Commission, 10 CFR 50.61, "Fracture Toughness Requirements for Protection against Pressurized Thermal Shock Events," 60 FR 65468, December 19, 1995, as amended at 61 FR 39300, July 29, 1996; 72 FR 49500, August 28,2007; 73 FR 5722, January 31, 2008. 2. Structural Integrity Associates Report, 0901132.401, Rev. 0, "Evaluation of Surveillance Data for Weld Heat No. W5214 for Application to Palisades PTS Analysis," April 20, 2010. Executive Summary The purpose of this letter is to document a review of the SIA report [2] that updated the pressurized thermal shock (PTS) screening criteria assessment for the Palisades reactor pressure vessel. A chemistry factor (CF) value of 227.4°F was determined in [2] based on post-irradiation surveillance test results specific to the Palisades vessel weld 2-112 NC, that contains weld wire heat number W5214 with Ni-200 wire addition.
| |
| The CF evaluation incorporates data from four different surveillance programs, and applies a conservative methodology to normalize the data for differences in chemistry and irradiation temperature.
| |
| The calculated 227.4°F CF value is more precise than a CF derived only from Cu and Ni content and more conservative than the results from the plant-specific surveillance capsules.
| |
| RT PTS projections for Palisades weld 2-112 NC were made using the 227.4°F CF. The 270°F PTS screening criterion
| |
| [1] for this axial weld is projected to be reached at a neutron fluence of 1.685E19 n/cm 2 (E> 1 MeV), which will be attained during the first quarter of 20 17. The assessment performed in [2] is reasonably and conservatively based. Therefore, it is conservative to project that the PTS screening criterion will not be reached in the Palisades reactor vessel until the first quarter of the year 2017. This projection is based on the assumption that the neutron fluence Page 2 of3 LTR-RIDA-1O-107-NP, Rev. 0 May l3, 2010 accumulation rate will continue as expected such that the 60° weld location fluence will reach 1.685E19 n/ cm 2 (E > 1 MeV) in the March 2017 -April 2017 time-frame.
| |
| Review and Discussion The integrity of the Palisades reactor pressure vessel is determined in part through an evaluation of the limiting RTPTS for the beltline materials.
| |
| The RT pTs is determined in accordance with 10 CFR 50.61 [1] and compared to screening criteria specific to the orientation of an assumed flaw. The Palisades reactor pressure vessel beltline consists of the lower and intermediate shell courses that are fabricated from six low-alloy steel plates and the adjoining welds. The focus of the evaluation is the limiting weld fabricated using wire heat number W5214 with Ni-200 wire addition.
| |
| The chemistry factor determined for this weld from Table 1 of [1] using best estimate copper (Cu) and nickel (Ni) content is stated in [2] as 231.08°F.
| |
| In [2], an update is provided to an earlier evaluation of data from reactor vessel surveillance capsules irradiated in Palisades and from three other reactor vessels. The data are specific to submerged arc weldments produced using wire heat number W5214 with Ni-200 wire addition.
| |
| The data specific to Palisades are from supplemental capsules SA-60-1 and SA-240-1.
| |
| The weld material was obtained from the Palisades retired steam generator and irradiated in the Palisades vessel. The three other sources of weld data applicable to wire heat number W5214 plus Ni-200 wire are H.B. Robinson Unit 2, Indian Point Unit 2, and Indian Point Unit 3. These other sources represent three unique surveillance program welds. The transition temperature shift measurements were determined using a consistent curve-fitting methodology.
| |
| The neutron fluence calculated for each evaluated surveillance capsule is obtained from recent sources. The surveillance data credibility analysis followed the criteria in [1], (c)(2)(i).

| Each of the five criteria were addressed subject to the extent of the information available from each of the four sources. The evaluation of surveillance data follows the approach described in [1], (c)(2) and (c)(3) with the addition of other considerations.
| |
| Those considerations include differences in best estimate weld chemistry and irradiation temperature.
| |
| Determination of chemistry factor (CF) given differences in copper and nickel content between the surveillance program weld and the Palisades reactor vessel weld is addressed in accordance with [1], (c)(2)(ii).
| |
| Accounting for the effect of differences in the irradiation temperature between the individual plant-specific surveillance capsules and the Palisades reactor vessel is performed using informal guidance provided by the NRC Staff and included in the referenced report. (For each 1°F that the capsule temperature exceeds the mean vessel temperature, the transition temperature shift is decreased by 1 OF. Likewise, a positive adjustment was applied to the shift for capsule temperatures lower than that of the vessel.) The two measured transition temperature shifts from Palisades (supplemental capsules SA-60-1 and SA-240-1) and the combined set of twelve measured shifts from the four sources, including adjustments for differences in copper and nickel content and for differences in irradiation temperature, were then analyzed using Equation 5 from [1]. The resultant CF Page 3 on LTR-RIDA-lO-l07-NP, Rev. 0 May 13, 2010 value was then assessed for predictability relative to each of the twelve adjusted transition temperature shifts. The evaluation of the two measured transition temperature shifts from Palisades resulted in a CP of 198.8°F. When assessed for predictability, the SA-60-1 and SA-240-1 measured shifts are within approximately 3°P of the prediction (within the one-sigma scatter of 28°P). An additional evaluation of the correlation monitor material from those Palisades supplemental capsules demonstrated the correlation monitor shift measurements to also be consistent with predictions.
| |
| Therefore, the plant-specific measurements are fully consistent with predictions.
| |
| The evaluation of the combined twelve measured tranSItion temperature shifts for four separate weldments produced using wire heat number W5214 with Ni-200 wire addition resulted in a CP of 227.4°P. When assessed for predictability, the twelve measured shifts are within approximately 46°P of the prediction (within the two-sigma scatter of 56°P). The 227.4°P CP value was used to project the RT PTS for the Palisades reactor vessel weld 2-112 AlC. The 270 0 P PTS screening criterion
| |
| [1] is projected to be reached at a neutron fluence of 1.685E19 n/cm 2 (E> 1 MeV). That fluence will be attained during the first quarter of 2017. The RT PTS projection is based on the assumption that the neutron fluence accumulation rate will continue as expected such that the 60° weld location fluence will reach 1.685E19 n/cm 2 (E > 1 MeV) in the March 2017 -April 2017 frame. In conclusion, this review finds that the assessment performed in [2], including the CP evaluation and the RT PTS projection, is reasonably and conservatively based.
