In May 2021, the SPE-CT facility for computed gamma tomography at the Research Centre Rez underwent its third major upgrade. One of the stated objectives was to assess the possibility of using the SPE-CT equipment for the TA CR TREND ALMARA project, which is the subject of this article. In this project, small cores of irradiated metals were cast into the studied fixation matrices. After matrix hardening, the possibility to determine by a non-destructive method the exact position of these coupons in the matrix was tested with the help of the device. The formation of corrosion products at the contact point between the two materials and the subsequent migration of radioisotopes in the matrix were also studied.
