Query: Detection of Missing Assemblies and Estimation of the Scattering
  Densities in a VSC-24 Dry Storage Cask with Cosmic-Ray-Muon-Based Computed
  Tomography   Highly energetic, cosmic-ray muons can easily penetrate a dry storage cask
and yield information about the material inside it by making use of the physics
of multiple Coulomb scattering. Work by others has shown this information may
be used for verification of dry storage cask contents after continuity of
knowledge has been lost. In our modeling and simulation approach, we use ideal
planar radiation detectors to record the trajectories and momentum of both
incident and exiting cosmic ray muons; this choice allows us to demonstrate the
fundamental limit of the technology for a particular measurement and
reconstruction method. In a method analogous to computed tomography with
attenuation coefficient replaced by scattering density is we apply a filtered
back projection algorithm in order to reconstruct both the geometry and
material information in modeled scenarios for concrete-walled cask VSC-24. A
scenario where one of the middle four spent nuclear fuel assemblies is missing
undetectable with a simple PoCA-based approach is expected to be readily
detectable with CT-based approach. Moreover, a trickier scenario where the one
or more assemblies is replaced by dummy assembly is put forward. In this case,
we expect that this dry storage cask should be found to be not as declared
based on our simulation and reconstruction results. Furthermore, we show that
the material composition can be estimated if the momentum of individual muons
can be precisely measured.
