Since 2015, the Helsinki Institute of Physics (HIP) has collaborated with the Finnish Radiation and Nuclear Safety Authority (STUK), the International Atomic Energy Agency (IAEA) and the Department of Mathematics and Statistics at the University of Helsinki to implement Passive Gamma Emission Tomography (PGET) of spent nuclear fuel in the nuclear safeguards protocols of the Onkalo geological repository.
The developments of the PGET method over the last few years will be summarized. These include investigations into the use of various gamma ray energy windows, measurements with spent fuel in air instead of water, development of a Serpent-based Monte Carlo simulation framework and the consideration of position-sensitive semiconductor detectors.
The future research directions will be presented. These mainly focus on improving the image reconstruction method and the implementation of position-sensitive semiconductor detectors. This research is embedded in the Flagship of Advanced Mathematics for Sensing, Imaging and Modelling (FAME), approved in 2023 by the Research Council of Finland.
