Abstract

The Arvia Process is being adapted for use in the nuclear industry for the decontamination of oils containing radionuclides. This waste treatment process uses adsorption followed by electrochemical oxidation as an alternative technique to conventional incineration. A study has been carried out on components of the Arvia Process with the aim of understanding the changes in chemistry due to ionizing radiation. Samples of adsorbent in water have been exposed to gamma-rays from a Co-60 irradiator at absorbed doses of 3, 19, and 304 kGy. Preliminary results show that the concentration of inorganic ions and carbon in the water increased as a function of dose. This increase suggests that degradation of the adsorbent may take place at high doses. Further characterization of the microstructure and adsorption studies post-irradiation are planned. (authors)
