Abstract : Nuclear propulsion engines operating in a cluster arrangement are subject to an exchange of neutron radiation. A method is presented of analysis suitable for parametric studies to determine the degree of neutronic coupling and how it affects engine performance and control stability. Results are presented for several representative nuclear engine designs in various cluster arrangements. The calculated reactivity coupling, using the albedo concept to represent the interchange of neutrons, is compared to experimental data for two KIWI B reactors. (Author)
