Abstract [en]

Tomography is a measurement technique that images the inner parts of objects using only externalmeasurement. It is widely used within the field of medicine, and may become important also fornuclear fuel verification where inspectors can obtain information from fuel assemblies’ inner sectionswithout dismantling them.

At Uppsala University, Sweden, a laboratory device has been built for investigating the tomographicmeasurement techniques on nuclear fuel. The device is composed of machinery to position model fuelrods, activated with Cs-137, in a fuel assembly pattern according to the user's choice. The gammaradiation from the model fuel assembly is collimated to a set of detectors that record the radiationintensity in various positions around the fuel model. Reconstruction of the gamma activity distributionwithin the fuel model is performed off-line.

The objective for constructing the laboratory device was to support the development of tomographictechniques for nuclear fuel diagnostics as well as for nuclear safeguards purposes. The device allowsfor evaluating the performance of different data-acquisition setups, measurement schemes andreconstruction algorithms, since the activity content of each fuel rod is well known.

For safeguards purposes, the device is unique in its capability to model various fuel geometries andconfigurations of partial defects. The latter includes removed, empty and substituted fuel rods. It iswell suited for developing tomographic techniques that are optimized for partial defect detection. Italso allows for development of analysis tools necessary to quantify detection limits.

Here, we describe the capabilities of the laboratory device and elaborate on how the device may beused to support the nuc
