Analysis of Human Intrusion Scenarios in the context of Site-Marking Concepts for Deep Geological Repositories — •Yannick Vogt and Friederike Frieß — Universität für Bodenkultur Wien, Institute of Safety and Risk Sciences, Department of Landscape, Water and Infrastructure, Peter-Jordan-Straße 76, 1190 Vienna, Austria

Scientific consensus suggests the disposal of high-level radioactive waste in deep geological repositories. Such repositories are to be protected against human intrusion. Here, a differentiation can be made between intentional and unintentional intrusion scenarios. Where unintentional intrusion describes intrusion by accident, intentional intrusion scenarios refer to the deliberate locating of a storage site, to recover the resource materials contained within, e.g. plutonium or copper.

Based on a comprehensive literature review, pathways are studied by which a repository might be entered. These pathways include drilling and mining activities, infrastructure projects, archaeological excavations, or military operations. Additional methodological approaches are explored, helping to broaden the horizon of scenario development, such as incorporating thematically related literary works or conducting a creative tabletop workshop.

This work aims to present a comprehensive overview of human intrusion scenarios. The presented results are part of a larger project on site-marking concepts for deep geological repositories.
