Effect of Anisotropic Scattering in PWR/APWR Radial-Reflector Calculations

摘要

Effect of anisotropic scattering on radial (baffle)-rnreflector calculations of PWR/APWR is evaluatedrnthrough detailed neutron transport calculation using thernAEGIS code. The calculation results indicated that therntransport correction on total cross section givesrnreasonable results, but the discrepancy may depend on therntype of reflector. Though incorporation of the Prnscattering overestimates leakage effect, utilization of thernP scattering almost covers the anisotropic scatteringrneffect in baffle-reflector analyses.
