가상현실 기반의 방사능방재 훈련시스템 구현 방법에 관한 연구

A Study for Implementing Virtual Reality Based Radiological Exercise System

2011년 일본 후쿠시마원전 사고 이후 방사능방재 요건이 크게 강화되었고 원전주변 비상계획구역의 확대로 훈련대상 인원도 크게 늘었다. 한편, 현재 진행 중인 인력동원 방사능방재훈련은 시나리오의 다양성 한계, 참여의 한계, 반복성의 한계 등의 문제점이 지적되고 있다. 이와 같은 인력동원의 문제점을 완화하기 위하여 가상현실을 활용한 방사능방재 훈련시스템의 필요성이 요구되고 있다. 본 논문에서는 가상현실 방사능방재 훈련시스템의 훈련시나리오를 구성하는 데 있어 사건수목기법의 활용에 대하여 소개하였다. 사건수목기법은 방사능방재 훈련을 주요 이벤트단위로 나누고, 이들 각각 단위들의 훈련주제를 기초로 가상현실 구현대상을 결정한다. 그리고 가상현실 구현이 용이하도록 관련된 개발 변수들을 목록화 한다.

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.
