A tomographic maximum entropy method is used to reconstruct the 3-D distribution of radioactive fission products in irradiated CANDU type fuel pins. The method has been implementated using a system similar to a single photon emission medical tomograph. It is used to study the behaviour of the nuclear fuel during irradiation and also for a Monte-Carlo simulation of the process of emission of gamma rays in order to improve the burn-up estimation. Experimentally results are reported to demonstrate the usefulness of the method in these kind of investigations.
