Several kinds of indoor wireless location technology are introduced in this paper, such as the Radio Frequency Identification (RFID), Bluetooth, Light Emitting Diode (LED) visible light location, and Ultra Wideband (UWB), which are analyzed and compared. Moreover, the paper also discusses the nuclear facilities physical protection system application of wireless location technology in nuclear power plant by means of collecting the location information of the internal authorized personnel to analyze the internal authorized personnel's behavior furthermore for the analysis of the internal threats with the data. And by using the wireless localization technologies it is expected to manage and control the nuclear materials in the real-time and achieve nuclear materials specified in the security area to prevent nuclear materials from being stolen or illegal transfer.
