In response to a regulatory mandate, all nuclear licensees are obligated to establish an information system that can provide essential information in the event of a radiation emergency by connecting the monitoring data of the Safety Parameter Display System (SPDS) or equivalent system to the Korea Institute of Nuclear Safety (KINS). Responding to this responsibility, the Korea Atomic Energy Research Institute (KAERI) has established the Safety Information Transmission System (SITS), which enables the collection and real-time monitoring of safety information. The KAERI monitors and collects safety information, which includes data from the HANARO Operation Work Station (OWS) and the HANARO & HANARO Fuel Fabrication Plant (HFFP) Radioactivity Monitoring System (RMS), and the Environmental Radiation Monitoring System (ERMS) & meteorological data. Currently, the transmission of this safety information to the AtomCARE server of the KINS takes place via the SITS server located in the Emergency Operations Facility (EOF). However, the multi-path of transmission through SITS has caused problems such as an increase in data transmission interruptions and errors, as well as delays in identifying the cause and implementing system recovery measures. To address these issues, a new VPN is currently being constructed on the servers of nuclear facilities that generate and manage safety information to establish a direct transmission system of safety information from each nuclear facility to the AtomCARE server. The establishment of a direct transmission system that eliminates unnecessary transit steps is expected to result in stable information transmission and minimize the frequency of data transmission interruptions. As of the improvement progress, a security review was conducted in the second and third quarters of 2022 to evaluate the security of newly introduced VPNs to the nuclear facility server, and based on the results of the review, security measures were strengthened. In the fourth quarter of 2022, the development of a direct transmission system for safety information began, and it is scheduled to be completed by the fourth quarter of 2023. The project includes the construction of the transmission system, system inspection, and comprehensive data stability testing. Afterward, the existing SITS located in the EOF will be renamed as the Safety Information Display System (SIDS), and there are plans to remove any unused servers and VPNs.

존 재난관리시스템은 피해상황을 실시간 입력이 아닌 우편물이나 팩스로 전송하여 입력하는 방식을 사용하여 실시간 처리가 안 되며, 지자체나 정부기관 등 기관이 조사하고 저장하고 있는 문서는 서로 상이한 형태나 내용으로 구성되어 전달 및 통합에 어려움이 있었다. 본 연구에서는 최근 증가하는 기상변동성 및 기후변화에 능동적으로 대처할 수 있도록 관련기관 및 관련자에게 수변구조물 피해정보와 복구지시를 정확하고 신속하게 전달을 위하여 e-문서 표준화 기술을 개발하였다. 기존 피해정보 및 복구지시 문서를 분석하여 가능한 모든 정보를 담고 유사한 항목을 하나의 항목으로 통일하여 중복정보를 제거하였다. 신속한 e-문서 전달을 위하여 e-문서 인터페이스를 구축하여 피해제보 및 피해 상황 보고 그리고 응급복구지시등의 표준 e-문서를 해당 기관에 신속하게 전달하고 해당 기관에 맞는 형태로 변환하여 전달하도록 설계하였다. 본 시스템을 활용하여 통합운영 및 전달 등의 연계기술 확보를 통한 선진국형 시설물 안전관리체계 구축 및 효율적인 재해대응으로 피해를 최소화하는데 도움을 줄 것으로 예상된다.

Since it is very important for an ocean-going vessel to transmit information quickly and accurately to her owner or charterer not only for the ship's safety but for economic operation of the ship, some newly-built automated vessels equipped with automatic information transmission system which consists of INMARSAT-C and specially-designed computer. This system, however, is not applicable to the existing vessel without chaging her equipments and, furthermore, is too expensive for small shipping companies to fit out such a system on their vessels. Therefore, we propose a low-priced information transmission system which consists of a personal computer and communication equipments in the existing vessel, and in this paper, as the groundwork of the proposed system, we have made up the ship's position transmission system which is composed of and IBM AT-compatible, PC, INMARSAT-A and a GPS receiver. As the test result of the system through sea trial on the training ship 'HANBADA', we confirmed that transmission of the ship's position was achieved succesfully and consequently there could be high possibility of cost-effectiveness of the proposed system
