Feasibility study for a pulsed cold neutron source at the University of Arizona TRIGA reactor

A computer code that utilizes the consistent energy dependent P1 equations and the multigroup diffusion equations was developed to calculate the cold neutron flux that could be generated if a cold neutron source was built at the University of Arizona TRIGA reactor. The cold neutron current at the surface of the cold neutron source and the energy deposition in the cold neutron source due to neutron-proton interactions were also calculated. The computer code models the cold neutron source as a spherically shaped hydrogen medium embedded in the center of a cylindrical shaped homogenous TRIGA core. The outputs of the computer code were compared for various cold neutron source dimensions
