A tomographic method for experimental verification of the integrity of spent nuclear fuel
A tomographic method for verification of the integrity of spent nuclear fuel assemblies has been developed. The gamma radiation field emanating from emitted radiation from within the assembly is recorded and utilised for reconstructing the internal source distribution. Simulations of an experimental procedure have indicated the ability of detecting the absence of fuel rods with high confidence. The method has been verified experimentally, both for a fuel model in laboratory environment and for spent fuel in a fuel handling pool.
