Securing nuclear materials is paramount. State physical protection systems provide a single system for planning, coordination, monitoring and implementation of the technical and organizational measures for the timely detection of unauthorized activities and prevent them. Physical protection should be provided at all stages of design, construction, operation and decommissioning of nuclear facilities, as well as any handling of nuclear materials and radioactive substances. The aim of this work is to create a hypothetical object, with which you can get the necessary data to assess the effectiveness with using the software "Vega-2."
