Abstract: Spent fuel stored in thick-walled strongly shielding casks can be indirectly verified through the application ofcontainment and surveillance measures. Assuring Continuity of Knowledge (CoK) of the spent fuel stored in dry spent fuelstorage facilities (SFSFs) for the upcoming decades is a cornerstone of safeguards. In the unlikely event that all Safeguardsrelatedcontainment and surveillance measures fail, a cask would need to be opened in the loading pond of a reactor. Therefore,substantially improved re-verification capabilities applicable to dry SFSFs are to be aimed at. The development of an adequatenon-destructive (re)-verification method for casks, proving the unchanged inventory of the verified spent fuel, would be a realadvantage for safeguards.Muon tomography could be a suitable method for the re-verification of self-shielding thick-walled spent fuel casks.To prove that the technology can detect the diversion of fuel assemblies, a two-modules muon detector has been designed andbuilt. It will be installed in the proximity of a spent fuel cask during a field test at a dry SFSF in Germany. The status of theproject and preliminary results will be presented.
