Direct Vitrification of Chloride Waste by Micro-Wave Heated OxygenPlasma

提出了利用氧等离子体直接玻璃化处理含氯废物的新方法。在本项目中，为了讨论这种直接玻璃化冷冻的科学可行性，已经进行了一些实验结果。在实验中，含有金属氯化物和玻璃材料的各种样品通过氧等离子体照射而玻璃化。从这些样品的分析中，获得了以下结果。短时间辐照使样品的晶体结构转变为非晶态结构，一定量的金属元素能使其各元素具有残留的特性，短时间辐照后样品中的氯被去除得最多。从这些结果可以看出，金属氯化物可以直接用氧等离子体玻璃化，我们提出的方法是非常强大的，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.
