DESCRIPTION:Verification of spent nuclear fuel is a prerequisi
 te for disposal in a geological repository. The ve
 rification method needs to be reliable and quick a
 nd allow non-destructive investigation of the fuel
  assemblies to ensure the integrity of the fuel pr
 ior to disposal. Recently IAEA has approved Passiv
 e Gamma Emission Tomography (PGET) to be used as a
  tool in rod-level examination of assemblies. In t
 his talk\, I&nbsp\;propose a method based on simul
 taneous reconstruction of activity and attenuation
  images with sufficient prior information\, formul
 ating the reconstruction as a constrained minimiza
 tion problem with a data fidelity term and regular
 ization terms.&nbsp\;The approach is shown to&nbsp
 \;produce clear reconstructions which allow for a 
 highly reliable classification of spent\, missing\
 , and fresh fuel rods. Several reconstruction exam
 ples from measured data will be presented in the t
 alk.
