Collaborative Risk Assessment in the Arctic: Lessons from the ATOMEX Tabletop Exercise and INCLUS Assessment Tool

Abstract: This paper explores the ATOMEX discussion-based tabletop exercise (TTX) and the experiences of using the INCLUS tool to map and assess risk perception based on different expertise. The study investigates how interactive browser-based assessment tool contributes to a shared understanding of risk evaluation in the Arctic. The paper discusses the importance of incorporating expert knowledge in shaping maritime risk awareness and decision-making processes. It highlights the need for expanded risk evaluation methodologies that prioritize key risk information and utilize visual representations of expert judgments. The survey conducted by the INCLUS tool with Arctic maritime rescue professionals and radiological and nuclear authorities provides insights into risk and preparedness perceptions. The findings emphasize the necessity of predefined guidelines, better training, clear roles and responsibilities, and improved communication systems to mitigate risks effectively. The ATOMEX exercise also emphasizes the complexity of Arctic maritime nuclear preparedness and the critical role of interactive data visualization tools like INCLUS in fostering a shared understanding of risks and enhancing collaborative decision-making.
