History And Evaluation Of The Performance Testing On The Physical Protection System Of Nuclear Facilities In Republic Of Korea

The IAEA instituted a series of publications on nuclear security to provide recommendations and guidance that States can use in establishing, implementing and maintaining their national nuclear security regime. The Republic of Korea enacted the Act of the Physical Protection and Radiological Emergency in accordance with the recommendations of the IAEA, Since 2016, force-on-force exercise has been conducted and evaluated as a performance test on the physical protection system of nuclear facilities. This study introduces the history of performance testing and suggests a method for evaluation and the direction of force-on-force exercise in the future. Performance testing of Republic of Korea is conducted by force-on-force exercise at least once a year in accordance with Act Article 9-3 of the Physical Protection and Radiological Emergency. More than 40 performance testing have been conducted since 2016, 18 of which have been conducted by force-on-force exercise. In force-on-force exercise, all respondents are equipped with MILES which includes GPS to collect the location information of the participants, called the training evaluation system. As a result, the moving distance, time, and speed of the adversary can be collected. The training evaluation system can collect location information of training participants in real time through GPS. The location information can be used to measure the distance between the adversary and the sabotage targets, resulting in an adversary time-distance graph of the target. The slope of the time-distance graph can derive the strengths and weaknesses of the physical protection system. By analyzing the movement speed information of the adversary, it was confirmed whether the proper physical protection system was designed for the nuclear facility from sabotage. In addition, this method can also be used to design physical protection systems. As a result of the performance testing conducted since 2016, physical protection system of nuclear facilities could be strengthened. However, in the design method of the physical protection system, it is necessary to study the delay effect according to the characteristics of the physical protection equipment.
