FLUX DISTRIBUTIONS, ADJOINT FUNCTIONS AND WEIGHTING FUNCTIONS FOR TIE HTR WITH 5 x 5 IPADINGS

摘要

The problem of calculating reactivity changes due to small changes in reactor composition or structure may be solved by perturbation methods These solutions require the calculated fast and slow neutron flux and adjoint flux distributions.nThis report presents these flux distributions as calculated for the 5x5 configuration. It also presents the tabulated fuel and poison weighting functions for each of 216 core positions, i.e. each fuel assembly is sub divided into eight vertically distributed cells.
