Passive high resolution gamma spectrometry was applied to determine the mass of the nuclear material in the inhomogeneous mixture of broken spent fuel pieces repacked into 72 canisters, following an incident in which 30 VVER-440 spent fuel assemblies became damaged and unusable. The HPGe detector wa...
