Material Signatures for Antineutrino-Based Detectability of Covert Fissile Production in Fusion Reactors

This project targets a key safeguards challenge: identifying covert fissile production pathways in nuclear fusion reactor settings using antineutrino observations. We will study whether novel material configurations (blankets, moderators, shielding, and structural composites) create measurable antineutrino-spectrum or time-profile signatures that improve detectability. The approach combines physics-informed simulation of reactor scenarios with statistical detection models and material sensitivity analysis. We expect to produce a ranked set of material candidates and monitoring strategies that improve early-warning capability while quantifying uncertainty and false-alarm risk.
