Westinghouse Non-Proprietary Class 3 A-1 APPENDIX A VALIDATION OF THE RADIATION TRANSPORT MODELS BASED ON NEUTRON DOSIMETRY MEASUREMENTS A.1 NEUTRON DOSIMETRY Comparisons of measured dosimetry results to both the calculated and least-squares adjusted values for all surveillance capsules withdrawn from service to date at St. Lucie Unit 2 are described herein. The sensor sets from these capsules have been analyzed in accordance with the current dosimetry evaluation methodology described in Regulatory Guide 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence" [Reference A-1]. One of the main purposes for presenting this material is to demonstrate that the overall measurements agree with the calculated and least-squares adjusted values to within +/- 20% as specified by Regulatory Guide 1.190, thus serving to validate the calculated neutron exposures previously reported in Section 6.2 of this report.A.1.1 Sensor Reaction Rate Determinations In this section, the results of the evaluations of the three surveillance capsules analyzed to date as part of the St. Lucie Unit 2 Reactor Vessel Materials Surveillance Program are presented.

The capsule designation, location within the reactor, and time of withdrawal of each of these dosimetry sets were as follows: Capsule Azimuthal Withdrawal Time Irradiation Time Location [EFPY]830 End of Cycle 1 1.11 2630 End of Cycle 9 11.07 970 End of Cycle 20 25.55 The passive neutron sensors- included in the evaluations of surveillance Capsules 83', 2630, and 970 are summarized as follows: WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-2 Reaction Of Capsule Capsule Capsule Sensor Material Interest 830 2630 970 Copper (Cd) 6 3 Cu(nu())6°Co X X X Titanium 4 6 Ti(n,p)4 6 Sc X X X Iron 5 4 Fe(n,p)5 4 Mn X X X Nickel (Cd) 5 8 Ni(n,p)5 8 Co X X X Uranium-238*

59C0(n Y)60 X X X Note:* The cobalt-aluminum and uranium monitors for this plant include both bare and cadmium-covered sensors.The capsules also contained sulfur monitors, which were not analyzed because of the short half-life of the activation product isotope (3 2 p, 14.3 days). Pertinent physical and nuclear characteristics of the passive neutron sensors analyzed are listed in Table A-1.The use of passive monitors such as those listed above do not yield a direct measure of the energy-dependent neutron fluence rate at the point of interest.

Rather, the activation or fission process is a measure of the integrated effect that the time- and energy-dependent neutron fluence rate has on the target material over the course of the irradiation period. An accurate assessment of the average neutron fluence rate level incident on the various monitors may be derived from the activation measurements only if the irradiation parameters are well known. In particular, the following variables are of interest:* the measured specific activity of each monitor,* the physical characteristics of each monitor,* the operating history of the reactor, a the energy response of each monitor, and* the neutron energy spectrum at the monitor location.The radiometric counting of the sensors from Capsule 970 was carried out by Pace Analytical Services, Inc. The radiometric counting followed established ASTM procedures.

The irradiation history of the reactor over the irradiation periods experienced by Capsules 830, 2630, and 970 was based on the monthly power generation of St. Lucie Unit 2 from initial reactor criticality through the end of the dosimetry evaluation period. For the sensor sets utilized in the surveillance capsules, the half-lives of the product isotopes are long enough that a monthly histogram describing reactor operation has proven to be an adequate representation for use in radioactive decay corrections for the reactions of interest in the exposure evaluations.

The irradiation history applicable to Capsules 830, 263', and 970 is given in Table A-2.WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-3 Having the measured specific activities, the physical characteristics of the sensors, and the operating history of the reactor, reaction rates referenced to full-power operation were determined from the following equation: A N o F Y Y P' Cj [1- e- t j] [e-Xt&J]Pref where: R = Reaction rate averaged over the irradiation period and referenced to operation at a core power level of Pref (rps/nucleus).

A = Measured specific activity (dps/g).No = Number of target element atoms per gram of sensor.F = Atom fraction of the target isotope in the target element.Y = Number of product atoms produced per reaction.Pi = Average core power level during irradiation period j (MW).Pref = Maximum or reference power level of the reactor (MW).C -= Calculated ratio of 4i(E > 1.0 MeV) during irradiation period j to the time weighted average f(E > 1.0 MeV) over the entire irradiation period.= Decay constant of the product isotope (1/sec).tj = Length of irradiation period j (sec).tdj = Decay time following irradiation period j (sec).The summation is carried out over the total number of monthly intervals comprising the irradiation period.In the equation describing the reaction rate calculation, the ratio [Pj]/[Pref]

accounts for month-by-month variation of reactor core power level within any given fuel cycle as well as over multiple fuel cycles. The ratio Cj, which was calculated for each fuel cycle using the transport methodology discussed in Section 6.2, accounts for the change in sensor reaction rates caused by variations in fluence rate level induced by changes in core spatial power distributions from fuel cycle to fuel cycle. For a single-cycle irradiation, Cj is normally taken to be 1.0. However, for multiple-cycle irradiations, the additional Cj term should be employed.

The impact of changing fluence rate levels for constant power operation can be quite significant for sensor sets that have been irradiated for many cycles in a reactor that has transitioned from WCAP- 1 7939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-4 non-low-leakage to low-leakage fuel management or for sensor sets contained in surveillance capsules that have been moved from one capsule location to another. The fuel-cycle-specific neutron fluence rate values along with the computed values for Cj are listed in Table A-3. These fluence rate values represent the capsule- and cycle-dependent results at the radial and azimuthal center of the respective capsules at core midplane.Prior to using the measured reaction rates in the least-squares evaluations of the dosimetry sensor sets, additional corrections were made to the 2 3 8 U cadmium-covered measurements to account for the presence of 2 3.U impurities in the sensors, as well as to adjust for the build-in of plutonium isotopes over the course of the irradiation.

Corrections were also made to the 2 3 8 U sensor reaction rates to account for gamma-ray-induced fission reactions that occurred over the course of the capsule irradiations.

The correction factors corresponding to the St. Lucie Unit 2 fission sensor reaction rates are summarized as follows: Correction Capsule 830 Capsule Capsule 970 2630 2 3 5 U Impurity/Pu Build- 0.8786 0.8459 0.8010 in 2 3 8 U(,,f) 0.8725 0.8757 0.8771 Net 2 3 8 U Correction 0.7666 0.7407 0.7026 The correction factors for Capsules 830, 2630 and 970 were applied in a multiplicative fashion to the decay-corrected cadmium-covered uranium fission sensor reaction rates.Results of the sensor reaction rate detenninations for Capsules 830, 263', and 970, are given in Table A-4.In Table A-4, the measured specific activities, decay-corrected saturated specific activities, and computed reaction rates for each sensor are listed. The cadmium-covered fission sensor reaction rates are listed both with and without the applied corrections for 2 3 5 U impurities, plutonium build-in, and gamma-ray-induced fission effects in the cases of Capsule 830 and 97'.A.1.2 Least-Squares Evaluation of Sensor Sets Least-squares adjustment methods provide the capability of combining the measurement data with the corresponding neutron transport calculations resulting in a best-estimate neutron energy spectrum with associated uncertainties.

Best-estimates for key exposure parameters such as fluence rate (E > 1.0 MeV)or dpa/s along with their uncertainties are then easily obtained from the adjusted spectrum.

In general, the least-squares methods, as applied to surveillance capsule 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 i +/-6 Ri ~(Cyig i p +/-~ )Qg 6 ,p g WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-5 relates a set of measured reaction rates, Ri, to a single neutron spectrum, kg, through the multigroup dosimeter reaction cross sections, c~ig, each with an uncertainty

5. The primary objective of the least-squares evaluation is to produce unbiased estimates of the neutron exposure parameters at the location of the measurement.

For the least-squares evaluation of the St. Lucie Unit 2 surveillance capsule dosimetry, the FERRET code [Reference A-2] 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 (fluence rate (E > 1.0 MeV) and dpa) along with associated uncertainties for the three in-vessel capsules analyzed to date.The application of the least-squares methodology requires the following input: 1. The calculated neutron energy spectrum and associated uncertainties at the measurement location.2. The measured reaction rates and associated uncertainty for each sensor contained in the multiple foil set.3. The energy-dependent dosimetry reaction cross sections and associated uncertainties for each sensor contained in the multiple foil sensor set.For the St. Lucie Unit 2 application, the calculated neutron spectrum was obtained from the results of plant-specific neutron transport calculations described in Section 6.2 of this report. The sensor reaction rates were derived from the measured specific activities using the procedures described in Section A. 1.1.The dosimetry reaction cross sections and uncertainties were obtained from the SNLRML dosimetry cross-section library [Reference A-3]. The SNLRML library is an evaluated dosimetry reaction cross-section compilation recommended for use in LWR evaluations by ASTM Standard E1018,"Application of ASTM Evaluated Cross-Section Data File, Matrix E706 (IEB)" [Reference A-4].The uncertainties associated with the measured reaction rates, dosimetry cross sections, and calculated neutron spectrum were input to the least-squares procedure in the form of variances and covariances.

The assignment of the input uncertainties followed the guidance provided in ASTM Standard E944,"Application of Neutron Spectrum Adjustment Methods in Reactor Surveillance" [Reference A-5].The following provides a summary of the uncertainties associated with the least-squares evaluation of the St. Lucie Unit 2 surveillance capsule sensor sets.Reaction Rate Uncertainties The overall uncertainty associated with the measured reaction rates includes components due to the basic measurement process, irradiation history corrections, and corrections for competing reactions.

A high level of accuracy in the reaction rate determinations is ensured by utilizing laboratory procedures that conform to the ASTM National Consensus Standards for reaction rate determinations for each sensor type.WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-6 After combining all of these uncertainty components, the sensor reaction rates derived from the counting and data evaluation procedures were assigned the following net uncertainties for input to the least-squares evaluation:

Reaction Uncertainty 63Cu(nl,(,)6°Co 5%5 4 Fe(n,p)5 4 Mn 5%5 8 Ni(n,p)5 8 Co 5%4 6 Ti(n,p)4 6 Sc 5%2 3 8 U(n,f)FP 10%5 9 Co(n,y)6°Co 5%These uncertainties are given at the l level.Dosimetry Cross-Section Uncertainties The reaction rate cross sections used in the least-squares evaluations were taken from the SNLRML library. This data library provides reaction cross sections and associated uncertainties, including covariances, for 66 dosimetry sensors in common use. Both cross sections and uncertainties are provided in a fine inultigroup structure for use in least-squares adjustment applications.

These cross sections were compiled from recent cross-section evaluations, and they have been tested for accuracy and consistency for least-squares evaluations.

Further, the library has been empirically tested for use in fission spectra determination, as well as in the fluence and energy characterization of 14 MeV neutron sources.For sensors included in the St. Lucie Unit 2 surveillance program, the following uncertainties in the fission spectrum averaged cross sections are provided in the SNLRML documentation package.Reaction Uncertainty 6 3 Cu(nct)6 0 Co 4.08-4.16%

5 4 Fe(n,p)" 4 Mn 3.05-3.11%

5 8 Ni(n,p)5 8 Co 4.49-4.56%

4 6 Ti(n,p)4 6 5c 4.50-4.87%

2 3 8 U(n,f)1 3 7 Cs 0.54-0.64%

5 9 Co(n,y)6 0 Co 0.79-3.59%

These tabulated ranges provide an indication of the dosimetry cross-section uncertainties associated with the sensor sets used in LWR irradiations.

Calculated Neutron Snectrum WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-7 The neutron spectra inputs to the least-squares adjustment procedure were obtained directly from the results of plant-specific transport calculations for each surveillance capsule irradiation period and location.

The spectrum for each capsule was input in an absolute sense (rather than as simply a relative spectral shape). Therefore, within the constraints of the assigned uncertainties, the calculated data were treated equally with the measurements.

While the uncertainties associated with the reaction rates were obtained from the measurement procedures and counting benchmarks and the dosimetry cross-section uncertainties were supplied directly with the SNLRML library, the uncertainty matrix for the calculated spectrum was constructed from the following relationship:

Mgg, +Rg *Rgn *Pgg, where &1 specifies an overall fractional normalization uncertainty and the fractional uncertainties Rg and Rg, specify additional random groupwise uncertainties that are correlated with a correlation matrix given by: Pg9, =[1-0169g, +0eH where H (g-g')2 2y 2 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 (0 specifies the strength of the latter term). The value of 6 is 1.0 when g = g', and is 0.0 otherwise.

The set of parameters defining the input covariance matrix for the St. Lucie Unit 2 calculated spectra was as follows: Fluence Rate Normalization Uncertainty (R 1) 15%Fluence Rate Group Uncertainties (Rg, Rg,)(E > 0.0055 MeV) 15%(0.68 eV < E < 0.0055 MeV) 25%(E < 0.68 eV) 50%Short Range Correlation (0)(E > 0.0055 MeV) 0.9 (0.68 eV < E < 0.0055 MeV) 0.5 WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-8 (E < 0.68 eV) 0.5 Fluence Rate Group Correlation Range (y)(E > 0.0055 MeV) 6 (0.68 eV < E < 0.0055 MeV) 3 (E < 0.68 eV) 2 A.1.3 Comparisons of Measurements and Calculations Results of the least-squares evaluations of the dosimetry from the St. Lucie Unit 2 surveillance capsules withdrawn to date are provided in Tables A-5, A-6, and A-7 for Capsules 830, 2630, and 970, respectively.

In these tables, measured, calculated, and best-estimate values for sensor reaction rates are given for each capsule. Also provided in this tabulation are ratios of the measured reaction rates to both the calculated and least-squares adjusted reaction rates. These ratios of M/C and M/BE illustrate the consistency of the fit of the calculated neutron energy spectra to the measured reaction rates both before and after adjustment.

Additionally, comparisons of the calculated and best-estimate values of neutron fluence rate (E > 1.0 MeV) and iron atom displacement rate are tabulated along with the BE/C ratios observed for each of the capsules.For Capsule 2630, the cadmium-covered uranium monitor was discarded.

For all three capsules, both bare and cadmium-covered cobalt-aluminum monitors were discarded.

For Capsule 970, the copper monitor was discarded.

The data for these dosimetry reactions were discarded because they were outside the expected values. For all capsules, the bare uranium monitors were not included because the U-235 impurity content and the thermal fluence rate on the capsule are not known with enough accuracy to correct the measurement readings.The data comparisons provided in Tables A-5 through A-7 show that the adjustments to the calculated spectra are relatively small and well within the assigned uncertainties for the calculated spectra, measured sensor reaction rates, and dosimetry reaction cross sections.

Further, these results indicate that the use of the least-squares evaluation results in a reduction in the uncertainties associated with the exposure of the surveillance capsules.

From Section 6.4 of this report, the calculational uncertainty is specified as 13% at the 1cy level.Further comparisons of the measurement results with calculations are given in Tables A-8 and A-9. These comparisons are given on two levels. In Table A-8, calculations of individual threshold sensor reaction rates are compared directly with the corresponding measurements.

These threshold reaction rate comparisons provide a good evaluation of the accuracy of the fast neutron portion of the calculated energy spectra. In Table A-9, calculations of fast neutron exposure rates in terms of fluence rate (E > 1.0 MeV) and dpa/s are compared with the best-estimate results obtained from the least-squares evaluation of the capsule dosimetry results. These two levels of comparison yield consistent and similar results with all measurement-to-calculation comparisons falling well within the 20% limits specified as the acceptance criteria in Regulatory Guide 1.190.In the case of the direct comparison of measured and calculated sensor reaction rates, for the individual threshold foils considered in the least-squares analysis, the average M/C comparisons for fast neutron WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-9 reactions range from 0.77 to 1.24 in the data set. The overall average M/C ratio for the entire set of St. Lucie Unit 2 data is 1.07 with an associated standard deviation of 13.8%.In the comparisons of best-estimate and calculated fast neutron exposure parameters, the corresponding BE/C comparisons for the capsule data sets range from 0.96 to 1.09 for neutron fluence rate (E > 1.0 MeV) and from 0.97 to 1.09 for iron atom displacement rate. The overall average BE/C ratios for neutron fluence rate (E > 1.0 MeV) and iron atom displacement rate are 1.02 with a standard deviation of 6.4% and 1.03 with a standard deviation of 5.9%, respectively.

Based on these comparisons, it is concluded that the calculated fast neutron exposures provided in Section 6.2 of this report are validated for use in the assessment of the condition of the materials comprising the beltline region of the St. Lucie Unit 2 reactor pressure vessel.WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-10 Table A-I Nuclear Parameters Used in the Evaluation of Neutron Sensors 90%Reaction Atomic Weight Target Product Fission Response of A tomi Atom Half-life Yield Range(a)Interest [g/g-atomJ Fraction [days] [%] RneVa 6 3 Cu (na) 6 0 Co 63.546 0.6917 1925.5 n/a 4.53- 11.0 4 6 Ti (n,p) 4 6 Sc 47.867 0.0825 83.79 n/a 3.70 -9.43 5 4 Fe (n,p) 5 4 Mn 55.845 0.05845 312.11 n/a 2.27-7.54 5 8 Ni (n,p) 5 8 Co 58.693 0.68077 70.82 n/a 1.98 -7.51 2 3 8 U (n,f) 1 3 7 Cs 238.051 0.99958 10983.07 6.02 1.44-6.69 5 9 Co (n,y) 6 0 Co 58.933 0.0017 1925.5 n/a non-threshold Notes: (a) The 90% response range is defined such that, in the neutron spectrum characteristic of the St. Lucie Unit 2 surveillance capsules, approximately 90% of the sensor response is due to neutrons in the energy range specified with approximately 5% of the total response due to neutrons with energies below the lower limit and 5% of the total response due to neutrons with energies above the upper limit (Reference A-6).WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-]lI Table A-2 Monthly Thermal Generation during the First 20 Fuel Cycles of the St. Lucie Unit 2 Reactor Cycle 1 Cycle 2 Cycle 3 Cycle 4 Month MWt-h Month MWt-h Month MWt-h Month MWt-h Jun-83 77926.4 Nov-84 92205 Jun-86 1944000 Nov-87 44010 Jul-83 449305.6 Dec-84 1137132 Jul-86 1767420 Dec-87 1717686 Aug-83 1776204.8 Jan-85 1980612 Aug-86 1809675 Jan-88 2004831 Sep-83 712576 Feb-85 1732374 Sep-86 1805706 Feb-88 1876149 Oct-83 1759590.4 Mar-85 1668411 Oct-86 1940733 Mar-88 2005047 Nov-83 1896012.8 Apr-85 1208763 Nov-86 504603 Apr-88 1968381 Dec-83 1814732.8 May-85 1879416 Dec-86 1937385 May-88 1942731 Jan-84 1525376 Jun-85 1944000 Jan-87 2001213 Jun-88 1988577 Feb-84 1671398.4 Jul-85 1876581 Feb-87 1809918 Jul-88 1940463 Mar-84 1903718.4 Aug-85 636444 Mar-87 1839456 Aug-88 1996110 Apr-84 1843200 Sep-85 636471 Apr-87 1881387 Sep-88 1986417 May-84 1834828.8 Oct-85 1921941 May-87 1880118 Oct-88 1844235 Jun-84 1843200 Nov-85 1944000 Jun-87 2000862 Nov-88 1985391 Jul-84 1840819.2 Dec-85 1767420 Jul-87 1708263 Dec-88 1943757 Aug-84 1901286.4 Jan-86 1809675 Aug-87 1904904 Jan-89 2007369 Sep-84 1216230.4 Feb-86 1805706 Sep-87 1942947 Feb-89 185814 Oct-84 854195.2 Mar-86 1940733 Oct-87 224100 Mar-89 0 Apr-86 504603 May-86 0 WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 A-12 Table A-2 (Continued)

The definition for USE is given in ASTM E185-82 [Ref. C-I], Section 4.18, and reads as follows: "upper shelf energy level -the average energy value for all Charpy specimens (normally three)whose test temperature is above the upper end of the transition region. For specimens tested in sets of three at each test temperature, the set having the highest average may be regarded as defining the upper shelf energy." Westinghouse reports the average of all Charpy data (>_ 95% shear) as the USE, excluding any values that are deemed outliers using engineering judgment.

Hence, the Capsule 970 USE values reported in Table C-1 were determined by applying this methodology to the Charpy data tabulated in Tables 5-1 through 5-4 of this report. USE values documented in Table C-I for the unirradiated material, as well as Capsules 830 and 263', were also determined by applying the methodology described above to the Charpy impact data reported in BAW-1880, Revision 0 [Ref. C-2], and WCAP-15040, Revision I[Ref. C-3]. The USE values reported in Table C-I were used in generation of the Charpy V-notch curves.The lower-shelf energy values were fixed at 2.2 ft-lb for all cases. The lower-shelf lateral expansion values were fixed at 1.0 mils in order to be consistent with the previous capsule analysis [Ref. C-3].Upper-shelf L.E. is not typically fixed in CVGRAPH; however, due to excessive data scatter for select capsule materials, the upper shelf L.E. value will be fixed in the summary plots, as documented in Section 5 of this report, for T-L and SRM materials in Capsule 263* and L-T and T-L materials in Capsule 97*. The individual L.E. plots for these materials, as documented in this Appendix, will still allow the upper-shelf L.E. to float for comparison between the two methods. The fixed upper-shelf L.E. values were determined using the same Charpy V-Notch test specimens that were used for the upper-shelf energy determinations and are shown in Table C-2.WCAP- 17939-NP May 2015 WCAP- 17939-NP May 2015 Revision 0 Westinghouse Non-Proprietary Class 3 C-2 Westinghouse Non-Proprietary Class 3 C-2 Table C-1 Upper-Shelf Energy Values (ft-lb) Fixed in CVGRAPH Intermediate Shell Plate M-605-1 Longitudinal Orientation 134 119 N/A 108 Intermediate Shell Plate M-605-1 103 102 79 78 Transverse Orientation Surveillance Program Weld Metal 115 100 105 95 (Heat # 83637)Heat-Affected Zone (HAZ) Material 105 119 130 93 Standard Reference Material (SRM) 122 N/A 86 N/A Table C-2 Upper-Shelf L.E.
