Abstract: Based on the nuclear power plant environment and virtual reality engine Unreal Engine4, a simulation platform for physical protection systems is built in this paper. The virtual reality simulation method is used to simulate the layout of the detection and defense devices of the physical protection system of the nuclear power plant under the condition of the closest real environment. In order to improve the defense level of the physical protection system, the security system designer can be assisted to identify the weak links of the detection device layout scheme by analysing the effectiveness of the detection device.

Key words: nuclear security, physical protection system, virtual reality, validity
