Abstract
The world nuclear industries and regulatory authorities have experienced many significant accidents, such as TMI-2, Chernobyl, and the Fukushima Daiichi accident. They strive to incorporate the lessons learned from these accidents into technologies, organizational operations, and even the behavior of individuals involved. They also continuously study the lessons derived from safety activities, including normal operations and maintenance. And through these reflections and research, they aim to establish a shared, dedicated, and effective "safety culture".
The key concepts, principles, requirements, and measures for nuclear safety established by the many nuclear organizations in the past, including the IAEA, are evident to be all essential to ensuring nuclear safety. However, the underlying concepts and true intentions behind them may not always be clear or easy to understand. To understand nuclear safety accurately and accessibly, it is significant to grasp the position and meaning of important aspects of nuclear safety and to comprehend the overall framework or structure and mechanisms that improve safety. To deeply understand these important matters, the author considers that narrative explanations (or storytelling) and visual aids (or visualizations) are needed, which allow us to go beyond surface-level comprehension and explore its essence to achieve a profound understanding of nuclear safety.
This paper reports some instances where such a lack of clarity exists and proposes measures for improvement.
