USE OF THE DISCRETE ORDINATE METHOD FOR DESCRIBING THE TRANSPORT OF FAST NEUTRONS THROUGH IRON SLABS

Abstract

The use of the discrete ordinate method for solving a simplified form of the neutron transport equation as a semi-empirical description of dose transmission through iron slabs was investigated. The basic information to which the model was fitted consists of a detailed set of Monte Carlo results which takes into account the incident energy and direction, the slab thickness and the exit direction. For 0.16-Mev neutrons, the fit was found to be excellent in all respects. At energies of 0.85, 1.2, 2.0 and 4.0 Mev, the total dose transmission was found also to give a good fit but its angular density and the total dose reflection were somewhat in error. (Author)
