SCALE 6.2.4 Validation: Reactor Physics

Abstract

This report is the third volume in a report series documenting the validation of SCALE 6.2.4, which is used herein with ENDF/B-VII.1 libraries, for nuclear criticality safety, reactor physics, and radiation shielding applications. This report focuses on validating SCALE capabilities that affect reactor physics applications. The experimental data used as basis for validation consists of measurement data for nuclide inventory, decay heat, and full-core experiments and include the following: NuclideNo. of samples Application a

SCALE 6.2.4: Validation Overview

“…It is optimized for thermal systems. This neutron cross section library is used in reactor physics [4] and nuclear criticality safety [3] validation with the CSAS, TRITON, and Polaris applications. However, it should not be relied upon for criticality safety analyses.…”

“…SCALE 6.2 uses these data to track 174 actinides, 1,149 fission products, and 974 activation products. These data are used in reactor physics validation [4] with the ORIGEN 1 and ORIGAMI applications.…”

“…This library contains over 700 materials and 12,000 neutron-induced reactions below 20 MeV. These data are used in reactor physics validation [4] with the ORIGEN and ORIGAMI applications.…”

“…NEWT is restricted to the use of MG cross sections. TRITON is used in the reactor physics validation volume [4].…”

“…This volume of the SCALE 6.2.4 validation reports connects all domain-specific validation volumes, describing the data and the tools used and summarizing the simulation results and their comparisons to measurements. The associated volumes contain additional detailed information on SCALE 6.2.4 validation in criticality safety [3], reactor physics [4], and shielding [5] applications. The range of systems, fuels, and materials in these applications is extensive; SCALE 6.2.4 is well validated for a variety of nuclear applications.…”
