Development of Technical Standard through Vehicle Barrier Test

The Nuclear Safety and Security Commission (hereinafter "NSSC") reflected the amended provisions to the Act on Physical Protection and Radiological Emergency (hereinafter "APPRE") in December 2013. In accordance with the revised APPRE, nuclear licensees are implementing strict physical protection and enhancing physical protection system. On the other hand, the vehicle crash has been occurred at national important facilities such as the vehicle crash of Gimpo Police in November 2014, the 1-ton truck crash of Asan City Hall in Aug. 2014, the 1- ton truck crash of Sejong Government Office in Apr. 2014, the drunk driving of Wonju City Hall in Nov. 2012. So, it is urgent to establish measures to provide substantial protection to national important facilities against vehicle crash. In this study, we conducted a field survey, selection of test objects and delayed performance tests for preparing practical countermeasures. The results of the vehicle crash tests on three kinds of delay equipment such as steel bollard, steel barricade, and stone bollard showed that the delayed effect of delaying the vehicle is very limited. Experiences and data obtained from the collision tests learned through this project will be used for establishing delayed car installation and operation standards for vehicle delay equipment in physical protection of national important facilities.
