Few-group baffle and/or reflector constants for diffusion calculation application
Technical Report
·
OSTI ID:6594496
Analysis of critical experiments for cross-section evaluation has been conducted on the basis of one dimensional four-group diffusion theory calculations which explicitly model the homogenized core and reflector in the radial plane. Such analyses require a reflector representation that models the leakage process as accurately as is feasible. This report describes the development and testing of few-group ENDF/B-V based light water reflector constants for use in diffusion theory which have been derived so as to reproduce leakage and other reaction rates from reference multifast group transport calculations. This work has been extended to parameterize similar higher order transport calculations with two- or four-group constants valid for application to typical PWR baffle/reflector configurations as represented in coarse mesh diffusion (PDQ) representations.
