A Study for Implementing Virtual Reality Based Radiological Exercise System

Abstract

After the radiological accident at Fukushima Japan in 2011, national and international requirements for emergency preparedness and response have been strongly enforced. Especially, the number of people subjected to be participated in an emergency exercise was largely increased according to the expansion of an emergency planning zone around nuclear power plants. Along with such changes in the circumstantial conditions it is widely acknowledged that there are great limitations in the varieties of the scenarios, limited numbers of the exercise participation by the general public, difficulties in repetitive conductions of a particular exercise due to limited resource of the current personnel mobilization exercise system, and so on. Therefore, new exercise technology such as the virtual reality based exercise system is required in order to meet the demand of the great soaring of the target participants in the exercises and alleviate the personnel mobilization difficulties through an alternative approach of an exercise system.In the study event tree methodologies are introduced to the employment in setting up the exercise scenario of the VR based radiological exercise system. According to the event tree methodologies, the phases of an emergency exercise are divided into units of major events, and the implementing objects of virtual reality are determined by the individual exercise topics of the major events. And also relevant variables of implementation are itemized for virtualization easily.
