Abstract
  • Instead of expensive and destructive chemical analysis, nondestructive assay (NDA) through radiography and tomography can be a faster, easier, and more appropriate method of analyzing spent nuclear fuel (SNF). As a preliminary study for the future design of a submersible SNF imaging system, this thesis demonstrates the ability of NDA to determine burnup and visualize fuel based on fission product concentrations through simulation with MCNP6.1 and SCALE6.2. This work investigates parameters for active radiographic measurements to study fuel metrology. Finally, this thesis evaluates two sinogram interpolation algorithms, two Algebraic Reconstruction Techniques (ART) and two back-projection algorithms for use in emission tomography image reconstruction. Conclusions include suggested active radiography system parameters and recommended image reconstruction techniques of those studied in this thesis.
