Modeling, simulations, database, and GUI: Updates on the Digital Twin for Nuclear Verification Project — •Manuel Kreutle1, Katharina Aymanns1, and Irmgard Niemeyer1, 2 — 1Forschungszentrum Jülich, Germany — 2International Atomic Energy Agency (IAEA), Vienna, Austria
Nuclear non-proliferation and disarmament efforts are centered around technical verification of related activities. This is true for bilateral agreements (e.g. New START, Open Skies, etc.) as well as multilateral treaties (e.g. NPT, CTBT, etc.). Past, present and potential future verification regimes are complex socio-technical systems that produce increasing amounts of data, nowadays usually in digital from. In convergence to that, "Digital Twins" have become a popular concept to monitor, predict or plan the behavior of cyber-physical systems. Hence it is just another step to combining the two.
In this talk, we will give an update on the state of a project on digital twins for safeguards in nuclear waste management. We will present a framework of database-enabled systems modeling, validated simulations, and visualization. The related software can produce realistic measurement and inspection data which can be displayed in a graphical user interface (GUI). In its current state it can be utilized to plan and improve monitoring systems, but we will discuss how it can be extended to allow for data processing of incoming real (live) data. We will close with sharing thoughts on how this project can be extended to create digital twins for nuclear verification in general.
