Nondestructive measurement of the radial two-dimensional distributions of fission products in irradiated fuel materials

OSTI ID:5339789
The radial two-dimensional isotopic distributions of fission products are determined by measuring diametral gamma scans or projections at two or more angular orientations and analytically unfolding these projections. This nondestructive examination technique has been applied to both fast-breeder-reactor and light-water-reactor irradiated fuel materials. It can be used to evaluate the relative migration of volatile fission products (iodine, cesium, tellurium) to the pellet-cladding interaction zone, as well as to determine the relative concentrations of less volatile fission products (ruthenium, niobium) within the fuel material. It is the only technique available to the experimenter for evaluating the distributions of fission and activation products within a fuel rod without destroying its integrity. 5 figures.
