Safeguards inspectors require reliable information to ensure that nuclear material in heavily shielded casks in dry spent fuel storage facilities is not diverted. In the event that all safeguards-related containment and surveillance measures fail, enhanced verification capabilities are needed. The MUTOMCA project aims to address this necessity by exploring muon tomography as a non-destructive assay method for re-verifying spent fuel casks. A detector setup was developed and tested and two algorithms were designed for reconstructing cask contents from muon absorption and scattering data respectively. A field test was performed with two loaded casks. This talk presents the muon detectors, data collection, preliminary results and future prospects.
