The nuclear power engineering and safety assurance problems require a great number of neutron-physical experiments to be performed on various plants (including power and research reactors, critical assemblies, exhaust fuel storage, etc.). Those investigations are characterized by the wide range of neutron flux variation (10-12 orders beginning from very low flux levels), the need for taking account of substantial differences in the physics of processes occurring in the objects studied and hence the necessity to use a wide range of measurement techniques. The Russian Scientific Centre "Kurchatov Institute" (RSC KI) has been long involved in construction of automated systems for complex studies of media neutron-physical parameters. The systems developed for this purpose are characterized by a unified approach to their functional structure. A brief outline of one of the latest designs is given.
