Abstract
Single (one-section) reactors, containing a neptunium–gallium or uranium–molybdenum alloy core, and coupled two-section systems, consisting of a single pulsed reactor and a driven subcritical assembly, consisting of a uranium–molybdenum alloy or dispersed uranium–graphite material, are studied. Calculations of the neutron and dynamical characteristics of these systems are performed. The information obtained, together with data from previous calculations, made it possible to draw a conclusion about the structure of reactor systems characterized by a short radiation pulse and large-volume cores and cavities for holding specimens. It is shown that a reactor with a single neptunium–gallium alloy core and a coupled cascade-type system consisting of this single driven reactor together with a driven subcritical uranium–graphite assembly have the best pulse parameters.
