Research on Defense-in-Depth Zone of Low-Altitude Security Area in Nuclear Power Plant

Abstract

AbstractIn recent years, international and domestic public facilities and nuclear facilities have repeatedly intruded by UAV. As a sensitive and important public facility, nuclear power plants need to consider how to against sabotage from UAV. The guidelines and guidance for the physical protection of nuclear facilities suggest that the design requirements for physical protection of nuclear facilities should be based on defense in depth, but there is no clear indication of defense-in-depth of the air. Therefore, in order to against sabotage from UAV, In the quantification of the establishment of air defense in depth according to the grade of nuclear power plants, it is applied to the physical protection design of nuclear power plants at this stage. The article analyzes the land occupation of various types of nuclear power plants, considering the three-factor defense and correlation of physical protection detection, delay and response. At the same time, the paper selects the main technical parameters of some UAVs and detective equipments as the basis of the defense-in-depth zone. Through all above analysis, the time and distance of defense-in-depth are quantified, combined with the function of detection, delay and response of physical protection. It is generalized the concept of a defense-in-depth zone of the air which is corresponded to the defense zone on the ground.KeywordsPhysical protectionDefense-in-depthDefending areaUAV (Unmanned aerial vehicle)DetectionDelayResponseControl areaProtect areaVital area
