Description

A feasibility study on a high-energy tomograph for radioactive waste examination has been carried out by CEA/SEDFMA (Cadarache, France). After describing the scope of the research (radiation source, detector system, data processing, station mechanics), this final report deals with the work programme which has been followed and gives the results of the research. The conclusion is that such a tomograph is feasible, and its preliminary design is shown. The main points are that: - the detector material will be BGO, - the transmission of gamma rays through concrete (up to 1 625 mm thick) has been measured and a calculation code has been validated, - the radiation source will be an accelerator which has to be carefully optimized, - the system configuration has been determined and the data processors have been chosen, - the algorithms for image reconstruction have been validated through taking a tomogram on a concrete sample
