摘要：

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 implemented 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 burnup estimation. Experimental results are reported to demonstrate the usefulness of the method in this kind of investigations.
