This study aims to propose a conceptual design of information displays for supporting responsive actions under severe accidents in Nuclear Power Plants (NPPs). Severe accidents in NPPs can be defined as accident conditions that are more severe than a design basis accident and involving significant core degradation. Since the Fukushima accident in 2011, the management of severe accidents is increasing important in nuclear industry. Dealing with severe accidents involves several cognitively complex activities, such as situation assessment; accordingly, it is significant to provide human operators with appropriate knowledge support in their cognitive activities. Currently, severe accident management guidelines (SAMG) have been developed for this purpose. However, it is also inevitable to develop information displays for supporting the management of severe accidents, with which human operators can monitor, control, and diagnose the states of NPPs under severe accident situations. It has been reported that Ecological Interface Design (EID) framework can be a viable approach for developing information displays used in complex socio-technical systems such as NPPs. Considering the design principles underlying the EID, we can say that EID-based information displays can be useful for dealing with severe accidents effectively. This study developed a conceptual design of information displays to be used in severe accidents, following the stipulated design process and principles of the EID framework. We particularly attempted to develop a conceptual design to make visible the principle knowledge to be used for coping with dynamically changing situations of NPPs under severe accidents.

ESG 경영은 CSR 경영이나 CSV 경영 등 기업의 자발적인 윤리 경영과는 달리 재무제표와 같은 공시 의무화를 기반으로 한 재무적 투자에 까지 영향을 미치고 있다는 점에서 경영 패러다임의 대전환이라고까지 할 수 있다. 이러한 상황에서 본 연구에서는 글로벌 경영 차원에서의 ESG 경영을 ‘글로벌 ESG 경영’이고 정의하고, 이를 개 도국을 중심으로 한 해외 사업에서의 글로벌 ESG 경영과 글로벌 공급망 관리 차원에서의 글로벌 ESG 경영으로 나누었다. 이러한 글로벌 ESG 경영의 관점에서 한국수력원자력에서 발표한 연도별 지속가능경영보고서와 관련 자료를 분석하고, 한수원 임직원에 대한 심층 인터뷰를 실시해 한국수력원자력의 글로벌 ESG 경영 사례를 분석 했다. 분석 결과 네팔 차멜리야 수력사업에서 현지 주민들에게 교통이나 통신, 수도 등의 인프라를 제공하고, 기술 인력과 기능 인력의 인권과 노동환경 개선을 위해 노력한 사례는 글로벌 ESG 경영의 모델이 될 수 있음을 확인 했다. 또한 한국수력원자력은 국내 ESG 경영 활동과 달리 해외 ESG 활동에서 주로 사회분야(S)에 집중되어 있 어 향후 환경(E)과 거버넌스(G)분야를 포함한 전체 ESG 분야에서 글로벌 경영을 추진할 필요성을 확인했다.

This article examines the consequences of a significant spent fuel management decision or event in the United States, South Korea and Taiwan. For the United States, it is the financial impact of the Department of Energy’s inability to take possession of spent fuel from commercial nuclear power companies beginning in 1998 as directed by Congress. For South Korea, it is the potential financial and socioeconomic impact of the successful construction, licensing and operation of a low and intermediate level waste disposal facility on the siting of a spent fuel/high level waste repository. For Taiwan, it is the operational impact of the Kuosheng 1 reactor running out of space in its spent fuel pool. From these, it draws six broad lessons other countries new to, or preparing for, nuclear energy production might take from these experiences. These include conservative planning, treating the back-end of the fuel cycle holistically and building trust through a step-by-step approach to waste disposal.
