ENDF/B-VII Nuclear Data Libraries for SCALE-6.0
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
Version 6 of the SCALE (Standardized Computer Analyses for Licensing Evaluation) code system was released in February 2009. SCALE provides a comprehensive, integrated package of modular programs and nuclear data for a wide range of applications, including reactor physics, criticality safety, shielding, sensitivity/uncertainty analysis, and isotopic transmutation and radiation source term determination. SCALE computational modules are executed by automated control sequences that prepare input and call the desired modules in a particular order, linking output from one calculation to the next in series. The SCALE lattice physics sequence TRITON generates few-group, assembly-homogenized cross sections, as a function of burnup and branch states, which can be input to core simulator codes. TRITON couples the ORIGEN-S depletion module with either the NEWT (NEW Transport algorithm) twodimensional (2D) arbitrary-geometry transport code or the three-dimensional Monte Carlo KENO code. Fluxes from the transport solution, along with self-shielded multigroup (MG) cross sections, are passed to ORIGEN-S, which computes the time-dependent isotopic concentrations of more than 1400 nuclides. One of the major advancements in SCALE 6 is the availability of new nuclear data libraries based on ENDF/BVII for neutron transport calculations. In this paper we describe the SCALE ENDF/B-VII (designated here as V7) libraries and present some validation results for critical benchmarks and isotopic depletion experiments.
