Composition and Radioactivity of Reactor Films
The concentration of inert elements and radioisotopes contained by the films on both fuel elements and aluminum process tubes were measured in selected samples taken from specimens of varying in- reactor exposures. The amounts of radioisotopes contained on a unit surface at any particular location on the three tubes increased with longer exposures, however, the differences were less noticeable in the case of isotopes of shorter half-life. Inert element concentrations were quite constant at a given location in the three process tubes, and the linear distributions could be described as an exponential function of distance. The linear distribution of inert elements on a fuel column with sixty days exposure could also be described by this function although higher concentrations were present. A different deposition pattern was exhibited by two fuel columns of lower exposure. Film composition was uniform along the length of the various process channels, with relative values approximating the respective ratios of the parent isotopes in process water. Corrosion of aluminum process tubes was shown to contribute only minor amounts to the radionuclides contained by the films on the tube surfaces. It is therefore concluded that most of the materials comprising the in-reactor film originated as impurities in …
