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 Capsules U, V, W, X, and Y are provided in this appendix. The sensor sets 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" [A-1]. One of the main purposes for providing 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 reported in Section 6.2.

A.1.1 Sensor Reaction Rate Determinations In this section, the results of the evaluations of Capsules U, V, W, X, and Y are presented. The capsules designation, locations within the reactor, and time of withdrawal are as follows:

Cobalt-AluminumCl) Co-59 (n,y) Co-60 X X X X X Notes:

1. The cobalt-aluminum sensors include both bare and cadmium-covered sensors.
2. These dosimeter sensor results are rejected due to large statistical scattering in the measurement data.

Since all of the dosimetry monitors were located at the radial center of the material test specimen array, gradient corrections were not required for these reaction rates. Pertinent physical and nuclear characteristics of the passive neutron sensors analyzed are listed in Table A-1.

The use of passive monitors does not yield a direct measure of the energy-dependent neutron exposure 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 exposure rate has on the target material over the course of the irradiation period. An accurate assessment of the average neutron exposure rate 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,
  • the energy response of each monitor, and
  • the neutron energy spectrum at the monitor location.

The radiometric counting of the sensors from Capsule Y was carried out by Pace Analytical Services, Inc.

The radiometric counting followed established ASTM procedures. The prevously withdrawn in-vessel Capsules U, V, W, and X were re-evaluated using the RAPTOR-M3G models described in Section 6.

The operating history of the reactor over the irradiation periods was based on the monthly power generation of Beaver Valley 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 for Cycle 1 through Cycle 11 is in [A-2]. The irradiation history for Cycle 12 through Cycle 20 is given in Table A-2.

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 R=---R~--------

NaFYI-1 e-[ 1 1 - e-Ati][e-Atct,i]

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.

P*J Average core power level during irradiation period j (MW).

Pref Maximum or reference power level of the reactor (MW).

C-J Calculated ratio of (E > 1. 0 Me V) during irradiation period j to the time weighted average (E > 1.0 MeV) over the entire irradiation period.

Decay constant of the product isotope (I/sec).

t-J Length of irradiation periodj (sec).

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]/[Pred 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 q , 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 exposure 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 q term should be employed. The impact of changing exposure 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 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.

Westinghouse Non-Proprietary Class 3 A-4 values are used to compute cycle-dependent values for q values 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 U-238 measurements to account for the presence of 235U 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 U-238 and Np-237 sensor reaction rates to account for gamma-ray-induced fission reactions that occurred over the course of the surveillance capsule irradiations. The correction factors corresponding to the Beaver Valley Unit 2 fission sensor reaction rates are summarized as follows:

Correction Capsule U Capsule V Capsule W Capsule X Capsule Y U-235 Impurity/Pu Build-in 0.8606 0.7888 na na na U-238 (y,f) 0.9779 0.9787 na na na Net U-238 Correction 0.8416 0.7720 na na na Np-237 (y,f) 0.9939 0.9940 0.9944 0.9940 na The correction factors were applied in a multiplicative fashion to the decay-corrected cadmium-covered fission sensor reaction rates.

Results of the sensor reaction rate determinations for the in-vessel Capsules U, V, W, X, and Y are given in Table A-3 through Table A-7. In Table A-3 through Table A-7, the measured specific activities, decay-corrected saturated specific activities, and computed reaction rates for each sensor are listed.

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 method, as applied to 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, Ri +/- 8Ri = ~)crig +/- 8a)(cp g +/- 8 cp) g relates a set of measured reaction rates, Ri, to a single neutron spectrum, <pg, through the multigroup dosimeter reaction cross-sections, CTig, each with an uncertainty 8. The primary objective of the least-squares evaluation is to produce unbiased estimates of the neutron exposure parameters at the location of the measurement.

Westinghouse Non-Proprietary Class 3 A-5 For the least-squares evaluation of the Beaver Valley Unit 2 dosimetry, the FERRET code [A-3] was employed to combine the results of the plant-specific neutron transport calculations and sensor set reaction rate measurements to determine the best-estimate values of exposure parameters (fluence rate (E > 1.0 MeV) and dpa) and their associated uncertainties.

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 Beaver Valley Unit 2 application, the calculated neutron spectrum was obtained from the results of plant-specific neutron transport calculations described in Section 6.2. 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 [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 E944, "Standard Guide for Application of Neutron Spectrum Adjustment Methods in Reactor Surveillance" [A-5].

The following provides a summary of the uncertainties associated with the least-squares evaluation of the Beaver Valley 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.

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:

58 Ni (n,p) 58 Co 5%

59 Co (n,y) 6°Co 5%

238 U (n,f) FP 10%

23 7 Np (n,f) FP 10%

These uncertainties are given at the 1cr 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 multigroup 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 Me V neutron sources.

For sensors included in the Beaver Valley Unit 2 surveillance program, the following uncertainties in the fission spectrum averaged cross-sections are provided in the SNLRML documentation package.

Reaction Uncertainty Cu-63 (n,a) Co-60 4.08--4.16%

Fe-54 (n,p) Mn-54 3.05-3.11 %

Ni-58 (n,p) Co-58 4.49--4.56%

Co-59 (n,y) Co-60 0.79-3.59%

U-238 (n,f) 0.54-0.64%

Np-237 (n,f) 10.32-10.97%

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

Calculated Neutron Spectrum 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).

Westinghouse Non-Proprietary Class 3 A-7 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:

where Rn 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:

Where:

(g- g')2 H=--

2y2 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 8 is 1.0 when g = g', and is 0.0 otherwise.

The set of parameters defining the input covariance matrix for the Beaver Valley Unit 2 calculated spectra was as follows:

Exposure Rate Normalization Uncertainty (Rn) 15%

Exposure Rate Group Uncertainties (Rg, Rg,)

(E > 0.0055 MeV) 15%

Westinghouse Non-Proprietary Class 3 A-8 A.1.3 Comparisons of Measurements and Calculations Results of the least-squares evaluations are provided in Table A-8 through Table A-12. In these tables, measured, calculated, and best-estimate values for sensor reaction rates are given. Also provided in these tabulations are ratios of the measured reaction rates to both the calculated and least-squares adjusted reaction rates. These ratios of measured-to-calculated (MIC) and measured-to-best estimate (MIBE) 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 best estimate-to-calculated (BEIC) ratios observed for each of the capsules.

The data comparisons provided in Table A-8 through Table A-12 show that the adjustments to the calculated spectra are relatively small and 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, the calculational uncertainty is specified as 13% at the lcr level.

Further comparisons of the measurement results with calculations are given in Table A-13 and Table A-14.

In Table A-13 , 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-14, calculations of fast neutron exposure rates in terms of fast neutron (E > 1.0 MeV) fluence rate and dpals are compared with the best-estimate results obtained from the least-squares evaluation of the capsule dosimetry results. These comparisons yield consistent and similar results with all measurement-to-calculation comparisons falling within the 20% limits specified as the acceptance criteria in Regulatory Guide 1.190.

In the case of the direct comparison of the measured and calculated sensor reaction rates, for the individual threshold foils considered in the least-squares analysis, the MIC comparisons of the fast neutron threshold reactions range from 0.88 to 1. 10. The overall average MIC ratio is 0.96 with an associated standard deviation of 6.6%.

In the case of the comparison of the best-estimate and calculated fast neutron exposure parameters, the BEIC comparisons are 0.93 and 0.95 for fast neutron (E > 1.0 MeV) fluence rate and iron atom displacement rate, respectively.

Based on these comparisons, it is concluded that the calculated fast neutron exposures provided in Section 6.2 are valid for use in the assessment of the condition of the materials comprising the beltline region of the Beaver Valley Unit 2 reactor pressure vessel.
