Zusammenfassung:The modeling of the neutronics of fuel assemblies on switching research reactors to low-enrichment fuel is examined. The specifications and computational results for three test problems of modeling the isotopic composition of spent nuclear fuel from a research reactor are presented. The test problems simulate fuel burnup in TVS-2M and -4M fuel assemblies of the IRT-1 reactor. It is shown that the contribution of plutonium isotopes to the energy release and their role in the neutron-physical characteristics of TVS-4M with deep burnup increase considerably on switching to low-enrichment fuel.
