Abstract
Physical protection system (PPS) is used to protect nuclear materials and nuclear facilities. The analyst evaluates the ability of the physical protection system to interrupt and neutralize the adversary intrusion by calculating the effectiveness of the physical protection system. The current physical protection effectiveness calculation tools use a constant value to assign the communication probability of the guard on duty to the response force. However, the assignment of communication probability is affected by many factors, such as human factors (information checking, call, etc.) and protection devices factors. Thus, this paper proposed a novel optimization method to optimizes the communication probability and obtained more accurate calculation results of system effectiveness based on the Sandia National Laboratory report. The case study indicates that the optimized method is more accurate and reasonable than the original method.
Highlights
The functions of the physical protection system (PPS) include detection, delay and response, which are used to reduce the possibility of damage and theft of nuclear facilities [1, 15]
By combining the functions of three-dimensional modeling of PPS with automatic twodimensional design drawing generation, an integrated platform for analysis and design (IPAD) of PPS was proposed to provide the designers with comprehensive and visualized information of PPS in one platform, which will enable a quick and convenient design of PPS [8]. The current tools such as SAVI and EASI adopt fixed value equivalents in the communication probability, which means that the on-site guards will notify the armed response force with a fixed communication probability after detecting the intrusion
Based on the Sandia National Laboratory report [1,2,3, 9], the author considers the relationship between the probability of communication and other factors, and adopts a more realistic scenario to simulate and optimize the communication probability of the guards, and compare the impact of the original and optimization on the effectiveness of the physical protection system as shown in figure 1
