Westinghouse Non-Proprietary Class 3A-1APPENDIX AVALIDATION OF THE RADIATION TRANSPORTMODELS BASED ON NEUTRON DOSIMETRYMEASUREMENTSA.1 NEUTRON DOSIMETRYComparisons of measured dosimetry results to both the calculated and least-squares adjusted values for allsurveillance capsules withdrawn from service to date at St. Lucie Unit 2 are described herein. The sensorsets from these capsules have been analyzed in accordance with the current dosimetry evaluationmethodology described in Regulatory Guide 1.190, "Calculational and Dosimetry Methods forDetermining Pressure Vessel Neutron Fluence" [Reference A-1]. One of the main purposes for presentingthis material is to demonstrate that the overall measurements agree with the calculated and least-squaresadjusted values to within +/- 20% as specified by Regulatory Guide 1.190, thus serving to validate thecalculated neutron exposures previously reported in Section 6.2 of this report.A.1.1 Sensor Reaction Rate DeterminationsIn this section, the results of the evaluations of the three surveillance capsules analyzed to date as part ofthe St. Lucie Unit 2 Reactor Vessel Materials Surveillance Program are presented. The capsuledesignation, location within the reactor, and time of withdrawal of each of these dosimetry sets were asfollows:Capsule Azimuthal Withdrawal Time Irradiation TimeLocation [EFPY]830 End of Cycle 1 1.112630 End of Cycle 9 11.07970 End of Cycle 20 25.55The passive neutron sensors- included in the evaluations of surveillance Capsules 83', 2630, and 970 aresummarized as follows:WCAP- 17939-NPMay 2015Revision 0 Westinghouse Non-Proprietary Class 3A-2Reaction Of Capsule Capsule CapsuleSensor Material Interest 830 2630 970Copper (Cd) 63Cu(nu())6°Co X X XTitanium 46Ti(n,p)46Sc X X XIron 54Fe(n,p)54Mn X X XNickel (Cd) 58Ni(n,p)58Co X X XUranium-238* 238U(n,f)FP X X XCobalt-Aluminum* 59C0(n Y)60 X X XNote:* 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 theactivation product isotope (32p, 14.3 days). Pertinent physical and nuclear characteristics of the passiveneutron 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 ameasure of the integrated effect that the time- and energy-dependent neutron fluence rate has on the targetmaterial over the course of the irradiation period. An accurate assessment of the average neutron fluencerate level incident on the various monitors may be derived from the activation measurements only if theirradiation 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, and970 was based on the monthly power generation of St. Lucie Unit 2 from initial reactor criticality throughthe end of the dosimetry evaluation period. For the sensor sets utilized in the surveillance capsules, thehalf-lives of the product isotopes are long enough that a monthly histogram describing reactor operationhas proven to be an adequate representation for use in radioactive decay corrections for the reactions ofinterest in the exposure evaluations. The irradiation history applicable to Capsules 830, 263', and 970 isgiven in Table A-2.WCAP- 17939-NPMay 2015Revision 0 Westinghouse Non-Proprietary Class 3A-3Having the measured specific activities, the physical characteristics of the sensors, and the operatinghistory of the reactor, reaction rates referenced to full-power operation were determined from thefollowing equation:ANo F Y Y P' Cj [1- e- tj] [e-Xt&J]Prefwhere:R = Reaction rate averaged over the irradiation period and referenced to operationat 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 timeweighted 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 irradiationperiod.In the equation describing the reaction rate calculation, the ratio [Pj]/[Pref] accounts for month-by-monthvariation of reactor core power level within any given fuel cycle as well as over multiple fuel cycles. Theratio Cj, which was calculated for each fuel cycle using the transport methodology discussed inSection 6.2, accounts for the change in sensor reaction rates caused by variations in fluence rate levelinduced by changes in core spatial power distributions from fuel cycle to fuel cycle. For a single-cycleirradiation, Cj is normally taken to be 1.0. However, for multiple-cycle irradiations, the additional Cj termshould be employed. The impact of changing fluence rate levels for constant power operation can be quitesignificant for sensor sets that have been irradiated for many cycles in a reactor that has transitioned fromWCAP- 1 7939-NP May 2015Revision 0 Westinghouse Non-Proprietary Class 3A-4non-low-leakage to low-leakage fuel management or for sensor sets contained in surveillance capsulesthat have been moved from one capsule location to another. The fuel-cycle-specific neutron fluence ratevalues along with the computed values for Cj are listed in Table A-3. These fluence rate values representthe capsule- and cycle-dependent results at the radial and azimuthal center of the respective capsules atcore midplane.Prior to using the measured reaction rates in the least-squares evaluations of the dosimetry sensor sets,additional corrections were made to the 238U cadmium-covered measurements to account for the presenceof 23.U impurities in the sensors, as well as to adjust for the build-in of plutonium isotopes over the courseof the irradiation. Corrections were also made to the 238U sensor reaction rates to account for gamma-ray-induced fission reactions that occurred over the course of the capsule irradiations. The correction factorscorresponding to the St. Lucie Unit 2 fission sensor reaction rates are summarized as follows:Correction Capsule 830 Capsule Capsule 9702630235U Impurity/Pu Build- 0.8786 0.8459 0.8010in238U(,,f) 0.8725 0.8757 0.8771Net 238U Correction 0.7666 0.7407 0.7026The correction factors for Capsules 830, 2630 and 970 were applied in a multiplicative fashion to thedecay-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 computedreaction rates for each sensor are listed. The cadmium-covered fission sensor reaction rates are listed bothwith and without the applied corrections for 235U impurities, plutonium build-in, and gamma-ray-inducedfission effects in the cases of Capsule 830 and 97'.A.1.2 Least-Squares Evaluation of Sensor SetsLeast-squares adjustment methods provide the capability of combining the measurement data with thecorresponding neutron transport calculations resulting in a best-estimate neutron energy spectrum withassociated 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, theleast-squares methods, as applied to surveillance capsule dosimetry evaluations, act to reconcile themeasured sensor reaction rate data, dosimetry reaction cross sections, and the calculated neutron energyspectrum within their respective uncertainties. For example,R i +/-6Ri ~(Cyig i p +/-~ )Qg6,pgWCAP- 17939-NP May 2015Revision 0 Westinghouse Non-Proprietary Class 3A-5relates a set of measured reaction rates, Ri, to a single neutron spectrum, kg, through the multigroupdosimeter 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 ofthe measurement.For the least-squares evaluation of the St. Lucie Unit 2 surveillance capsule dosimetry, the FERRETcode [Reference A-2] was employed to combine the results of the plant-specific neutron transportcalculations and sensor set reaction rate measurements to determine best-estimate values of exposureparameters (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 multiplefoil set.3. The energy-dependent dosimetry reaction cross sections and associated uncertainties for eachsensor contained in the multiple foil sensor set.For the St. Lucie Unit 2 application, the calculated neutron spectrum was obtained from the results ofplant-specific neutron transport calculations described in Section 6.2 of this report. The sensor reactionrates 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 dosimetrycross-section library [Reference A-3]. The SNLRML library is an evaluated dosimetry reactioncross-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 calculatedneutron spectrum were input to the least-squares procedure in the form of variances and covariances. Theassignment 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 theSt. Lucie Unit 2 surveillance capsule sensor sets.Reaction Rate UncertaintiesThe overall uncertainty associated with the measured reaction rates includes components due to the basicmeasurement process, irradiation history corrections, and corrections for competing reactions. A highlevel of accuracy in the reaction rate determinations is ensured by utilizing laboratory procedures thatconform to the ASTM National Consensus Standards for reaction rate determinations for each sensortype.WCAP- 17939-NP May 2015Revision 0 Westinghouse Non-Proprietary Class 3A-6After combining all of these uncertainty components, the sensor reaction rates derived from the countingand data evaluation procedures were assigned the following net uncertainties for input to the least-squaresevaluation:Reaction Uncertainty63Cu(nl,(,)6°Co 5%54Fe(n,p)54Mn 5%58Ni(n,p)58Co 5%46Ti(n,p)46Sc 5%238U(n,f)FP 10%59Co(n,y)6°Co 5%These uncertainties are given at the l level.Dosimetry Cross-Section UncertaintiesThe reaction rate cross sections used in the least-squares evaluations were taken from the SNLRMLlibrary. This data library provides reaction cross sections and associated uncertainties, includingcovariances, for 66 dosimetry sensors in common use. Both cross sections and uncertainties are providedin a fine inultigroup structure for use in least-squares adjustment applications. These cross sections werecompiled from recent cross-section evaluations, and they have been tested for accuracy and consistencyfor least-squares evaluations. Further, the library has been empirically tested for use in fission spectradetermination, 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 thefission spectrum averaged cross sections are provided in the SNLRML documentation package.Reaction Uncertainty63Cu(nct)60Co 4.08-4.16%54Fe(n,p)"4Mn 3.05-3.11%58Ni(n,p)58Co 4.49-4.56%46Ti(n,p)465c 4.50-4.87%238U(n,f)137Cs 0.54-0.64%59Co(n,y)60Co 0.79-3.59%These tabulated ranges provide an indication of the dosimetry cross-section uncertainties associated withthe sensor sets used in LWR irradiations.Calculated Neutron SnectrumWCAP- 17939-NPMay 2015Revision 0 Westinghouse Non-Proprietary Class 3A-7The neutron spectra inputs to the least-squares adjustment procedure were obtained directly from theresults of plant-specific transport calculations for each surveillance capsule irradiation period andlocation. The spectrum for each capsule was input in an absolute sense (rather than as simply a relativespectral shape). Therefore, within the constraints of the assigned uncertainties, the calculated data weretreated equally with the measurements.While the uncertainties associated with the reaction rates were obtained from the measurement proceduresand counting benchmarks and the dosimetry cross-section uncertainties were supplied directly with theSNLRML library, the uncertainty matrix for the calculated spectrum was constructed from the followingrelationship:Mgg, +Rg *Rgn *Pgg,where &1 specifies an overall fractional normalization uncertainty and the fractional uncertainties Rg andRg, specify additional random groupwise uncertainties that are correlated with a correlation matrixgiven by:Pg9, =[1-0169g, +0eHwhereH (g-g')22y2The first term in the correlation matrix equation specifies purely random uncertainties, while the secondterm describes the short-range correlations over a group range y (0 specifies the strength of the latterterm). 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 wasas follows:Fluence Rate Normalization Uncertainty (R1) 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) 0.5WCAP- 17939-NP May 2015Revision 0 Westinghouse Non-Proprietary Class 3A-8(E < 0.68 eV) 0.5Fluence Rate Group Correlation Range (y)(E > 0.0055 MeV) 6(0.68 eV < E < 0.0055 MeV) 3(E < 0.68 eV) 2A.1.3 Comparisons of Measurements and CalculationsResults of the least-squares evaluations of the dosimetry from the St. Lucie Unit 2 surveillance capsuleswithdrawn 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 eachcapsule. Also provided in this tabulation are ratios of the measured reaction rates to both the calculatedand least-squares adjusted reaction rates. These ratios of M/C and M/BE illustrate the consistency of thefit of the calculated neutron energy spectra to the measured reaction rates both before and afteradjustment. 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 foreach of the capsules.For Capsule 2630, the cadmium-covered uranium monitor was discarded. For all three capsules, both bareand cadmium-covered cobalt-aluminum monitors were discarded. For Capsule 970, the copper monitorwas discarded. The data for these dosimetry reactions were discarded because they were outside theexpected values. For all capsules, the bare uranium monitors were not included because the U-235impurity content and the thermal fluence rate on the capsule are not known with enough accuracy tocorrect the measurement readings.The data comparisons provided in Tables A-5 through A-7 show that the adjustments to the calculatedspectra are relatively small and well within the assigned uncertainties for the calculated spectra, measuredsensor reaction rates, and dosimetry reaction cross sections. Further, these results indicate that the use ofthe least-squares evaluation results in a reduction in the uncertainties associated with the exposure of thesurveillance capsules. From Section 6.4 of this report, the calculational uncertainty is specified as 13% atthe 1cy level.Further comparisons of the measurement results with calculations are given in Tables A-8 and A-9. Thesecomparisons are given on two levels. In Table A-8, calculations of individual threshold sensor reactionrates are compared directly with the corresponding measurements. These threshold reaction ratecomparisons provide a good evaluation of the accuracy of the fast neutron portion of the calculatedenergy 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-squaresevaluation of the capsule dosimetry results. These two levels of comparison yield consistent and similarresults with all measurement-to-calculation comparisons falling well within the 20% limits specified asthe acceptance criteria in Regulatory Guide 1.190.In the case of the direct comparison of measured and calculated sensor reaction rates, for the individualthreshold foils considered in the least-squares analysis, the average M/C comparisons for fast neutronWCAP- 17939-NP May 2015Revision 0 Westinghouse Non-Proprietary Class 3A-9reactions range from 0.77 to 1.24 in the data set. The overall average M/C ratio for the entire set ofSt. 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 correspondingBE/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 ratiosfor neutron fluence rate (E > 1.0 MeV) and iron atom displacement rate are 1.02 with a standard deviationof 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 inSection 6.2 of this report are validated for use in the assessment of the condition of the materialscomprising the beltline region of the St. Lucie Unit 2 reactor pressure vessel.WCAP- 17939-NPMay 2015Revision 0 Westinghouse Non-Proprietary Class 3A-10Table A-I Nuclear Parameters Used

The definition for USE is given in ASTME185-82 [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 insets of three at each test temperature, the set having the highest average may be regarded asdefining the upper shelf energy."Westinghouse reports the average of all Charpy data (>_ 95% shear) as the USE, excluding any values thatare deemed outliers using engineering judgment. Hence, the Capsule 970 USE values reported inTable C-1 were determined by applying this methodology to the Charpy data tabulated in Tables 5-1through 5-4 of this report. USE values documented in Table C-I for the unirradiated material, as well asCapsules 830 and 263', were also determined by applying the methodology described above to theCharpy 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 expansionvalues 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 selectcapsule materials, the upper shelf L.E. value will be fixed in the summary plots, as documented inSection 5 of this report, for T-L and SRM materials in Capsule 263* and L-T and T-L materials in Capsule97*. The individual L.E. plots for these materials, as documented in this Appendix, will still allow theupper-shelf L.E. to float for comparison between the two methods. The fixed upper-shelf L.E. valueswere determined using the same Charpy V-Notch test specimens that were used for the upper-shelf energydeterminations and are shown in Table C-2.WCAP- 17939-NP May 2015WCAP- 17939-NPMay 2015Revision 0 Westinghouse Non-Proprietary Class 3C-2Westinghouse Non-Proprietary Class 3 C-2Table C-1 Upper-Shelf Energy Values (ft-lb) Fixed in CVGRAPHIntermediate Shell Plate M-605-1Longitudinal Orientation134119N/A108Intermediate Shell Plate M-605-1 103 102 79 78Transverse OrientationSurveillance Program Weld Metal 115 100 105 95(Heat # 83637)Heat-Affected Zone (HAZ) Material 105 119 130 93Standard Reference Material (SRM) 122 N/A 86 N/ATable C-2 Upper-Shelf L.E.
