Abstract

The paper presents the development of a neutron noise simulator for fast reactors based on diffusion theory with multi-energy groups. The noise sources are modelled via small stationary fluctuations of macroscopic cross sections, and the induced first order noise is solved fully in the frequency domain. The tool is expected to be applicable for monitoring of fast reactor cores and also for other reactor types with hexagonal fuel assemblies. Some numerical calculations of the neutron noise induced by localized perturbations in a sodium-cooled fast reactor are demonstrated.
