Neutron characteristics of models of a cascade two-section blanket

Experiments on cascade-reactor models

“…Such assemblies are structurally simple and compact, and they contain a comparatively small number of fissioning materials and satisfy, without taking any special protective measures, nuclear safety requirements. The calculations of nuclear-physical characteristics of assemblies with low values of k eff have confirmed that such assemblies are acceptable as models for the experiments mentioned above [18] been shown that the difference of the effectiveness of the models of the ordinary and cascade blankets in this case is small, but nonetheless sufficient to be detected in an experiment. The measurements and analysis of the primary results of the experiments were accompanied by comprehensive calculations performed using primarily the S-95 computer code [19] for obtaining a Monte Carlo solution of the equations of neutron and γ-ray transport.…”
