Description

Combustible Radioactive Waste Injection Module and Mobile Radioactive Waste Disposal Apparatus Including It}

The present invention relates to a combustible radioactive waste input module and a mobile radioactive waste treatment apparatus including the same, and more particularly, a combustible radioactive waste input module capable of minimizing the possibility of exposure of workers by automating the process of introducing the combustible radioactive waste, and It relates to an integrated container-type incineration facility equipped with a miniaturized radioactive waste incineration treatment device in a transportable container including the same.

In general, radioactive waste generated when operating a nuclear power plant or nuclear-related facilities is generally stored in a storage facility such as a nuclear power plant or a management facility such as a radioactive waste disposal site. However, by constructing the radioactive waste disposal site, the cost required for the final disposal of radioactive waste is considerable, and in reality, there is a lot of burden.

In particular, in the event of an unexpected accident such as the Fukushima nuclear power plant accident, there are so many radioactive wastes that it is impossible to manage it through a radioactive waste disposal site. Accordingly, there is a method of burning and disposing of radioactive waste by using an incinerator as an example of the prior art for reducing the quantity of radioactive waste and treating it. By incineration of the radioactive waste as described above, the amount of radioactive waste can be reduced, and there is an advantage in that a large amount of radioactive waste can be reduced and treated at once.

However, the above-described radioactive waste incineration treatment also has limitations on the installation space due to the enlarged facility, and generates civil complaints from local residents because it generates incineration ash and exhaust gas contaminated by radioactivity.
