Science for Nuclear Diplomacy

We develop “nuclear archaeology” methods to reconstruct fissile material production and removal. This involves simulations of nuclear fuel cycles and facilities and applying computational techniques and data science methods.

Radiation detection is crucial for nuclear verification. Our group simulates nuclear material detection and reactor operations, complemented by experimental work using gamma and neutron sources and passive detection systems in the group’s laboratory.

Beyond technical research, we engage in interdisciplinary initiatives. The VeSPoTec project explores the connections between technical analyses, nuclear governance, and confidence-building practices. By integrating natural science, social constructivism, strategic studies, and the sociology of knowledge, we aim to address challenges to verification regimes. 

The group is part of the Cluster for Natural and Technical Science Arms Control Research (CNTR). The group also encompasses the junior research group “nuSENTRY” (Neutrino-based Safeguards for Emerging Nuclear Technology and Reactor Types) at TU Darmstadt led by Yan-Jie Schnellbach.
