Dry casks for spent nuclear fuel (SNF) ensure the safe storage of SNF and provide radiation shielding. However, presence thick encompassing several layers steel concrete makes inspection a challenging task. Fast neutron interrogation is viable method nondestructive assay dry casks. In this study, we performed Monte Carlo simulation-based study associated with machine-learning-based image recons...

Cosmic-ray muons can be used for the non-destructive imaging of spent nuclear fuel in sealed dry storage casks. The scattering data after traversing provides information on thereby penetrated materials. Based these properties, we investigate and discuss theoretical feasibility detecting single missing rods a cask first time. We perform simulations vertically standing generic model loaded with a...

The goal of this research is to determine the gamma-ray dose contribution from skyshine. In a transportation accident involving the loss of lead gamma shielding, first responders to the accident will be exposed to both direct gamma radiation streaming from the exposed spent nuclear fuel and atmospherically reflected gamma radiation. The reflected radiation is referred to as skyshine and should ...
