The purpose of the work is to develop and carry out research based on the SCA Neutron Source to ensure its safe operation and conduct research with neutrons in various fields of fundamental science, energy, materials science, biophysics, medicine, ecology, and other areas. The research method is the experimental and industrial operation of the Neutron Source at the NSC KIPT with the aim of developing methods for measuring its neutron-physical characteristics, which were used during the physical start-up (PSU). As a result of this work, methods for measuring the effective neutron multiplication factor and reactivity of the facility were developed and experimentally confirmed. The measurement results were compared with the results of modeling using the MCNPX code. The measurement results were analyzed. Conclusions were made about the results of measuring the neutron characteristics of the Neutron Source nuclear facility in relation to the design values, about ensuring nuclear and radiation safety during the (PSU), and about the possibility of licensing the further operation of the Subcritical Assembly (SCA) “Neutron Source”.
