Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

The leaching behavior of real Zircaloy cladding hulls, originating from the pressurized water reactor nuclear power station at Obrigheim, Federal Republic of Germany, was investigated using distilled water; nitric acid; sodium hydroxide solution; Portland, alumina, and Sorel cement lye solutions; and a potassium pyrosulfate melt as leachants. The leached fraction was determined for six gamma-emitting isotopes and two actinides. The distributions of the radionuclides in the hulls were determined using a potassium pyrosulfate melt. The results indicated that actinides (plutonium and curium) were concentrated on the surface; the diffusing species (ruthenium and cesium) had high concentrations at the surface but also appeared in the inner portions of the hulls. The distribution of activation products (cobalt and antimony) was very nearly homogeneous throughout the hulls. It is recommended that, prior to reprocessing, the Zircaloy-clad fuel rods be separated from the fuel assembly to facilitate handling of the alpha-contaminated waste stream. The results of this study show that decontamination with nitric acid should be sufficient for further conditioning prior to disposal if conditioning is required.
