FLUX DISTRIBJTI0NS, ADJOINT FUNCTIONS AND WEIGHTING FACTORS FOR THS MTR WITH 5 x 6 LOADINGS

摘要

When the operation of the MTR with a 5 x 6 core configuration was proposed it was decided to calculate the fast and slow neutron fluxes and their adjoints. These are needed to give estimates of fluxes, reactivity perturbations, and to calculate fuel requirements to give fixed periods of operation.nThis report presents calculated fast (above thermal) aid slow (thermal) fluxes together with the corresponding adjoint functions for the MTR with a 5x6 core configuration. It tabulates the fuel and poison weighting factors for the core lattice positions and presents a thermal flux map (based on these calculations) of the tank section.
