초록

후쿠시마 사고와 같은 중대사고에 대비하기 위하여 극한환경 내에서도 동작하여 원자력 발전소 내부 상태에 관련된 계측신호를 취득하고, 사고복구에 필요한 밸브, 펌프 등과 같은 비상기기를 작동시킬 수 있는 극한환경용 제어기기와 발전소로부터 최소 30km 떨어진 곳에서 발전소 내부 상황을 감시하고, 제어할 수 있는 모바일 원격 제어실 등으로 구성된 비상대응시스템이 필요하다. 본 논문에서는 극한환경용 제어기기와 모바일 원격 제어실과의 연계를 위한 비상대응시스템 개념 설계 및 성능분석에 대하여 논의하였다. 비상통신시스템은 IEEE 802.11 기술표준을 이용한 지상망과 천리안 위성을 이용한 위성망의 이중화 시스템으로 구성되고, 각 시스템에 대하여 통신링크 버짓, Throughput, 지연시간을 분석하였다.

To cope with sever accident like Fukushima accident, the emergency response system is needed. It consist of the hardened I&C system and the mobile control station. The hardened I&C system monitors the state in the nuclear power plant and controls the emergency equipment such as valves, pumps and the mobile control station placed at 30km away from nuclear power plant receives the status information from the hardened I&C system and transmits the control data to the hardened I&C system. In this paper, we design the emergency communication system connecting the hardened I&C system to the mobile control station and analyze the performance of the system. This system consists of the terrestrial communication system and the satellite communication. The performance such as a communication link budget, throughput and delay time is analyzed for each system.
