| Research Abstract |
As a new method to treat the chloride waste discharged from the future pyrochemical reprocessing we propose the direct vitrification of chloride waste by using oxygen plasma. In this project, to discuss about the scientific feasibility of this direct vitrification, several experimental results has been carried out. in experiments various samples which contain a metal chloride and glass materials are vitrified by the oxygen plasma irradiation. From the analy ses of these samples, the following results were obtained. Cry stal structure of the sample changes into amorphous one by a short time irradiation, a certain amount of metal elements can remainits each element has a characteristic for remaining Chlorine is mostly removed from the samples after a short time irradiation. From these results we can conclude that metal chlorides can be vitrified directly by using oxygen plasma and the method which we suggested is very powerful and has a large potential for practical use.
