Title: Some aspects of thermal neutron diffusion in non-uniform temperature moderator.
Authors: Thompson, JJ
Issue Date: Jul-1959
Publisher: Australian Nuclear Science and Technology Organisation
Abstract: The effect of non-uniform temperature on the Maxwellian distribution of thermal neutrons in a non-capturing moderator has been studied, using the heavy gaseous moderator approach. The results indicate that for typical temperature gradients in power reactors, the neutron temperature follows the moderator temperature with a negligible distortion of the spectrum, and that at the boundary between regions of different temperature, perturbations are restricted to a few centimeters.
