Abstract
The dissolver residues arising from delayed precipitation from light-water reactor fuel solution have been shown to consist of metal colloids. This has been revealed using photographic and X-ray fluorescence analyzes of the dissolver residues incorporating high resolution electron microprobe techniques. Evaluation of a number of microparticles showed the identical chemical composition of the epsilon -phase, known as 'white inclusions' from fast breeder fuel elements. These microanalyzes also indicated that precipitates of oxidic phases of Mo and Tc, previously believed to be almost insoluble metal acids, could also have been formed as radiation-induced oxidation products of primary metallic precipitates. Moreover, segregation of colloidal silver halides has been observed in fission products, their agglomeration as microscopic AgX bodies possessing a crystal symmetry already well established macroscopically.
