.. _sec-data: SCALE Cross Section Libraries ============================= *A. Holcomb, D. Wiarda, C. Celik, K. S. Kim, M. L. Williams, M. E. Dunn, B. T. Rearden* ABSTRACT The cross section data libraries available in the SCALE code system are briefly described in this section. All libraries were processed from ENDF/B-VII.1 and -VIII.0 evaluated data files using the AMPX code system. Continuous-energy libraries as well as several multigroup libraries for a variety of applications are included in SCALE. Several fine-group and broad-group structures are available so that a user may select the nuclear data library based on considerations of application, accuracy, and execution time. ACKNOWLEDGMENTS We would like to acknowledge all those who participated in developing and implementing the SCALE cross section libraries for their assistance in preparing previous versions of this document. Special thanks go to S. Goluoglu, N. M. Greene, and L. M. Petrie for their contributions to SCALE data processing efforts, and to C. R. Daily and W. J. Marshall for their extensive validation testing of the libraries described here. Introduction ------------ SCALE includes both multigroup (MG) and pointwise continuous energy (CE) nuclear data libraries, which were processed using the AMPX code system :cite:`XSL-wiarda_ampx_2015`. Libraries are available for neutron and for coupled neutron-photon transport calculations. The CE libraries are used for Monte Carlo calculations with CE-KENO (criticality) and CE-Monaco (shielding), and are also used by the pointwise (PW) discrete ordinates code CENTRM to obtain PW flux spectra for computing self-shielded MG cross sections. The MG libraries are used in the MG-KENO and MG-Monaco Monte Carlo codes, and in the deterministic transport codes XSDRNPM, NEWT, and DENOVO. All cross section libraries in SCALE 6.3 and later versions are based strictly on ENDF/B-VII.1 :cite:`XSL-chadwick_endfb-vii_2011` and ENDF/B-VIII.0 :cite:`XSL-brown_endfb-viii_2018`, while earlier SCALE releases included libraries processed from ENDF/B-VI.8, V, and IV. The ENDF/B-VII.1 CE and MG libraries include the 423 nuclides shown in :numref:`table10-1-1`, and the ENDF/B-VIII.0 CE and MG libraries contain data for 556 nuclides (Note that while ENDF/B-VIII.0 contains data for neutron-as-a-target, this data is not useful for SCALE calculations and is thus the processed data is not released with SCALE.). ENDF does not have evaluated data for several isotopes in the SCALE Standard Composition Data; therefore the libraries do not include cross sections for these nuclides, which are listed in :numref:`table-10-1-2`. If one of these isotopes is explicitly requested or if the natural element containing the isotope is requested in the SCALE input, a warning message is written saying that the nuclide is being omitted from the calculations. The most commonly encountered example of this is O-18 which has an abundance of approximately 0.2% in elemental oxygen (Note that O-18 data are available in ENDF/B-VIII.0, but not ENDF/B-VII.1.). The ENDF/B-VII.1 libraries include 21 thermal-scattering moderators for which bound-scattering kernels [e.g., S(:math:`\alpha`,\ :math:`\beta`)] are provided as given in :numref:`table-10-1-3`. This table also lists the temperatures available in MG and CE libraries for the materials with bound kernels. The ENDF/B-VIII.0 libraries include 34 thermal-scattering moderators for which bound-scattering kernels are provided; of particular interest are updated thermal scatter laws for HinH2O and multiple graphite compositions. The thermal scattering kernels for all other materials are based on the free-gas kernel. On the MG libraries, these nuclides have 2D scattering matrices processed from the free-gas kernel evaluated at the temperatures of 293 K, 565 K, 600 K, 900 K, 1200 K, 2000 K, and 2400 K. SCALE 6.3 includes routines that automatically interpolate the CE cross section data, as well as thermal scattering kernels to any arbitrary temperature for Monte Carlo calculations :cite:`XSL-hart_creation_2016`. Analogous procedures are available for MG data. The CE libraries do not include free gas kernel data because the transport codes internally evaluate the free gas scattering information at the specified temperature. For each reaction and nuclide, CE data were processed from ENDF/B in the manner described in :numref:`10-1-2-5`. The CE data were further processed into several generic MG libraries focused on different applications. CE data are stored as individual files for each nuclide, and an associated cross section directory file contains the names of the individual files. Furthermore, the MG libraries each contain data for all nuclides. AMPX master libraries are very general and contain essentially all reaction data available in ENDF/B, as well as several specialized cross sections used in SCALE. The master libraries also include Bondarenko shielding factors tabulated as a function of background cross section and temperature for all nuclides and groups, and the master libraries may contain intermediate resonance parameters for self-shielding. A much improved methodology in AMPX was used to process more accurate shielding factors for the most important resonance absorbers.\ :sup:`1` The CE and MG libraries available in SCALE 6.3 are given in :numref:`table-10-1-4`, which also lists the main source of data for each library. The desired MG or CE library for a computation is typically selected by specifying the appropriate mnemonic name from :numref:`table-10-1-4`. The CE library mnemonic corresponds to the actual name of the cross section directory file, and the MG mnemonic is an alias for the file containing the actual master library, shown in the third column of :numref:`table-10-1-4`. SCALE control modules recognize the mnemonics in the first column, or the standard MG library name in the third columns of the table. Users also may supply their own MG library by specifying the file name as the library name in the control module input (only lower case alphanumeric characters are allowed in the filename, and the filename must be eight characters or less in length). The library must be an AMPX master library and must be located in the SCALE data directory or the temporary working directory where the problem is run. The CE data libraries do not require additional processing prior to their use in transport computations. However the MG libraries distributed with the SCALE code system contain problem-\ *independent* cross sections processed with generic weighting functions appropriate for a specified type of application (e.g., criticality safety, shielding, etc.). These data must be further processed into problem-\ *dependent* libraries by performing resonance self-shielding and other modifications. This is done by the :ref:`XSProc module ` during the execution of a SCALE control sequence prior to executing a transport solver. .. tabularcolumns:: | m{2cm} | m{2cm} | m{2cm} | m{2cm} | m{2cm} |

The 252-group structure was developed to adequately capture spectral and temperature effects important for reactor systems and was processed with newer, improved procedures. The SCALE control sequences for criticality safety and reactor physics applications normally perform self-shielding of the fine-group libraries using the BONAMI module for the unresolved resonance range; and the CENTRM/PMC modules for the resolved resonance/thermal range. However the 252-group libraries include Bondarenko self-shielding factors for the entire energy range, which provides the option of using the Bondarenko method to self-shield both the resolved and unresolved resonance ranges, as an alternative to the more rigorous (and computationally intensive) CENTRM/PMC approach. As discussed in the following section, one objective of the ENDF/B-VII.1 and ENDF/B-VIII.0 252-group and 56-group libraries was to provide a more accurate Bondarenko treatment for the resolved resonance range. Differences in the 238-group and 252-group libraries ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The standard weighting function described in :numref:`table-10-1-6` is typically used to create MG data for all materials in a library, and Bondarenko shielding factors can be computed using the narrow resonance (NR) approximation for the flux spectrum: :math:`\sigma`\ :sub:`t`\ + :math:`\sigma`\ :sub:`0`)*C(E) where :math:`\sigma`\ :sub:`0` is the background cross section, and C(E) is the standard weight function. Bondarenko factors are tabulated at temperatures of at 293 K, 565 K, 600 K, 900 K, 1200 K, 2000 K, and 2400 K in the 252-group library. .. table:: Standard weighting function for processing MG data. :class: longtable :name: table-10-1-6 +-----------------------------------+-----------------------------------+ | **Energy Range** | **Standard Weight Function** | +===================================+===================================+ | 10\ :sup:`-5` eV - 0.1 eV | Maxwellian, with peak at 0.025 eV | +-----------------------------------+-----------------------------------+ | 0.1 eV - 80 keV | 1/E | +-----------------------------------+-----------------------------------+ | 80 keV - 10 MeV | Watt Fission spectrum at | | | temperature of 1.273 MeV | +-----------------------------------+-----------------------------------+ | 10 MeV -20 MeV | 1/E | +-----------------------------------+-----------------------------------+ Several enhancements were made in the MG processing procedures used to produce the 252-group library so that it would be more applicable to reactor physics as well as criticality safety applications. Some of the improvements in the 252-group library compared to the SCALE-6.2 238-group library are given below (a) The base weighting function for processing MG data of actinide materials (Z>89) was computed by the PW transport code CENTRM for a PWR lattice at 300 K. This approach provides more representative weighted 2D scattering matrices for most cases of interest. The standard weighting function is still used for materials with Z<90. (b) The thermal energy range which includes up-scattering reactions was extended to 5 eV, compared to 3 eV in the SCALE 6.2 238-group library (c) Temperature-dependent thermal-scattering matrices for water-bound H, O-16, and actinide materials were processed with temperature-dependent thermal flux spectra obtained from CENTRM calculations for a PWR pincell. Actinide and O-16 MG thermal scattering kernels were weighted with the fuel zone flux at temperatures of 293 K, 600 K, 900 K, 1200 K, and 2400 K, and the water scatter kernels were weighted with the moderator flux at 293 K, 500 K, 600 K, 650 K, 900 K, and 1200 K. In the SCALE 6.2 238-group library, thermal scattering matrices at all temperatures were weighted with a temperature-independent Maxwellian spectrum. (d) Group-dependent IR parameters ("lambdas") were calculated for all materials and are included in the 252-group libraries. This allows the Bondarenko self-shielding method in SCALE to use the IR approximation for the 252-group libraries, while the SCALE 6.2 238-group library was limited to the NR approximation. (e) A number of improvements were made in processing of Bondarenko self-shielding data. - The number of temperatures for the Bondarenko factors was increased. Shielding factors are tabulated at temperatures 292 K, 600 K, 900 K, 1200 K, and 2400 K for the 252-group libraries. - In addition to the Bondarenko factors normally included for capture, fission, elastic, and total cross sections, self-shielding factors are also included for the multigroup elastic within-group cross section to address the impact of resonance reactions on the scattering distribution. - In the unresolved resonance range, self-shielding factors were calculated using probability tables. - Bondarenko factors for nuclides with atomic masses Z>39 were calculated with CENTRM PW flux spectra rather than the analytical NR approximation. Two types of CENTRM models were used. Heterogeneous models of water-moderated lattices spanning the range of expected self-shielding were used to calculate shielding factors for :sup:`235`\ U, :sup:`238`\ U, :sup:`239`\ Pu, :sup:`240`\ Pu, :sup:`241`\ Pu, :sup:`90`\ Zr, and :sup:`96`\ Zr. The CENTRM transport calculations were performed using the method of characteristics method for 2D unit cell models. Homogeneous models were used to compute shielding factors for the remaining nuclides with Z>39. These CENTRM calculations were performed for homogeneous media containing the absorber material mixed with hydrogen, and the hydrogen concentration was varied to obtain the desired set of background cross sections. :numref:`table-10-1-7` summarizes the processing options for the 252-group library. .. table:: Standard weighting functions for processing 252-group library data library. :class: longtable :name: table-10-1-7 +-----------------------+-----------------------+-----------------------+ | **Nuclide** | **Base Weight | **Bondarenko Factor** | | | Function** | | +=======================+=======================+=======================+ | U-238, -235; Pu-239, | PWR spectrum | CENTRM heterogeneous | | -240, -241 | | calculations | +-----------------------+-----------------------+-----------------------+ | Other actinides Z>90 | PWR spectrum | CENTRM homogeneous | | | | calculations | +-----------------------+-----------------------+-----------------------+ | 39
