Neutron kinetics investigations at the zero-power LR-0 reactor in Czechoslovakia are described. The reactor is fueled with WWER-1000 assemblies. Reactivity perturbations generated by absorber cluster movements are investigated. It can be shown that, under certain conditions, space-dependent effects can be corrected by a simple model. The experimental results are used to verify a nodal three-dimensional, two-group neutron kinetics code.
