Abstract
The digital Cerenkov viewing device (DCVD) developed by the Canadian and Swedish Safeguards Support Programs was successfully used to characterize Cerenkov images obtained from fuel and non-fuel assemblies from a Russian designed pressurized water-cooled and water-moderated power reactor (WWER). The fuel assemblies are characterized by their high degree of light collimation and the non-fuel assemblies by their lack of light collimation. Digital data from the images permits quantification of fuels with similar burnup and a range of cooling times and fuel assemblies with the same cooling time and different burnups. The comparison of the experimental with the theoretical data was excellent.
