Direct Vitrification of Chloride Waste by Micro-Wave Heated OxygenPlasma

作为一种新的处理方法，我们提出了利用氧等离子体直接玻璃化处理含氯废物的方法。在这个项目中，为了讨论这种直接玻璃化的科学可行性，进行了几个实验结果。在实验中，各种含有金属氯化物和玻璃材料的样品被氧等离子体辐照玻璃化。通过对这些样品的分析，得到了以下结果。样品经短时间辐照后，晶体结构转变为无定形结构，可保留一定量的金属元素，每种元素都有其自身的特点，短时间辐照后，样品中的余氯大部分被去除。从这些结果可以看出，金属氯化物可以用氧等离子体直接玻璃化，我们所提出的方法是非常强大的，具有很大的实际应用潜力。

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.
