Radioactive Waste Decontamination
Radioactive Metallic Waste Decontamination
Decontamination methods for radioactive wastes include wet and dry treatment.
The existing method is mostly wet treatment method to facilitate desalinization of acids, but it requires a number of nearby facilities, such as decommissioning costs and waste disposal facilities, and requires complicated treatment process and a large number of secondary wastes.
In reality, a single or more complex process is selected depending on the level of radionuclides and waste radiation, form and state, and one of the important criteria is to minimize the effects for waste audits and the ease of radiation exposure.
Therefore, if there is a dry method that can reduce the amount of desalinization facilities and reduce the amount of secondary waste, the amount of radioactive wastes produced by nuclear facilities can be reduced safely and dramatically.
Currently, development of dry decontamination technology is underway worldwide.
Plasma Decontamination Technology
UJU Enertech has developed a plasma dry desalinization technology that was originally developed by Hanyang University's Advanced Nuclear Materials & Plasma Engineering.
The basic principle of plasma contamination technology is to generate plasma gas that contains elements that produce volatile compounds in response to contaminated nuclides, and to remove them by selectively reacting to highly contaminated radioactive nuclides.
Currently, the company completed the optimal decontamination process for uranium, supermanium elements, corrosion products, fission products, cos, and Mo nuclides, which are considered major pollutants.

Plasma Decontamination Technology Demonstration
For demonstration, this technology has designed a plasma dry desalinization facility of the prototype antisalization products, such as uranium and supernic element (TRU, TRANsUranic element)
In particular, it has proven to be a very practical technology, as inducing a pulse type DC voltage or ion injection etching can further enhance the desalinization rate. Currently, this process has been certified as a new technology (NET) in 2010 (authentication no. 0212), and a batch dry desalinization pilot facility that can be applied to the site was developed and the 2nd National Green Technology Economy Award in 2010.
