TL;DR: In this article, the PGET head consists of two banks of 104 CdTe detectors each with integrated data acquisition electronics, which can be rotated around the fuel element using an integrated stepping motor mounted on a rotating table.

TL;DR: The Passive Gamma Emission Tomography (PGET) as discussed by the authors was developed for the IAEA Safeguards for verification of irradiated nuclear fuel assemblies (SFAs) in 2015-2016 and its performance has been tested on multiple SFA types.

TL;DR: The potential for gamma emission tomography (GET) to detect partial defects within a spent nuclear fuel assembly is assessed through a collaboration of Support Programs to the International Atomic Energy Agency (IAEA) as discussed by the authors.

TL;DR: In this article, the authors used the filtered backprojection algorithm from measurements with a passive gamma emission tomography prototype instrument at Finnish nuclear power plants to reconstruct gamma-ray images of VVER-440 and SVEA-96 spent nuclear fuel assemblies.

TL;DR: In this article, the performance of a passive neutron albedo reactivity (PNAR) instrument to measure neutron multiplication of spent nuclear fuel in borated water is investigated as part of an integrated non-destructive assay safeguards system.
