abstract = {The MUTOMCA (MUon TOMography for shielding CAsks) project
is dedicated to investigate the suitability of muon
tomography for the re-verification of loaded spent fuel
casks. The loss of continuity of knowledge (CoK) in the
hypothetical case that the containment and surveillance
measures of EURATOM/IAEA would temporarily fail during the
decades of dry storage of spent fuel, requires a technology
for re-verification of the spent fuel enclosed in
self-shielding casks. In such a case the inspectorates need
to have a high degree of assurance on the amounts of nuclear
material stored in the dual-purpose casks (casks for
transport and storage). The re-verification is particularly
challenging for conventional non-destructive-assay (NDA)
methods, as the thick-walled CASTOR® V cask considerably
attenuates the radiation emitted by the spent fuel. With the
aim of proving the ability of muon tomography to detect a
diversion of fuel assemblies in closed spent fuel casks, a
two-module muon detector was designed, developed,
constructed and commissioned. The detector, which is based
on drift tube technology, was used in a field trial in the
first months of 2023 in a dry storage facility in Germany to
measure two CASTOR® V casks with different inventories.
During the implementation of the field trial sufficient data
was recorded to secure the evaluation of the capability of
the muon tomography to fulfill the safeguards requirements
for re-verification. Based on the results of the field test,
this contribution will assess the potentials and the
drawbacks of the experimental apparatus for the application
of the reconstruction technique and will present a
preliminary evaluation of the data. The MUTOMCA research
project was established by INFN Padova and Forschungszentrum
Jülich GmbH (FZJ) in collaboration with BGZ Company for
Interim Storage (BGZ Gesellschaft für Zwischenlagerung mbH)
and the European Commission, Directorate-General for
Energy.},
