Ⅱ. Perpose
Environmentally-clean technologies for the decontamination of radioactive contaminants are urgently needed in the future because of stronger environmental law expected. Decontamination using supercritical fluids can eliminate the secondary waste due to the easy recycle process by press

Ⅱ. Perpose
Environmentally-clean technologies for the decontamination of radioactive contaminants are urgently needed in the future because of stronger environmental law expected. Decontamination using supercritical fluids can eliminate the secondary waste due to the easy recycle process by pressure.
In this study, the following decontamination technologies are developed using supercritical fluids. 1) decontamination of actinides, 2) decontamination of radioactive metal ions, and 3) contaminated metal coating removal by emulsion.

Ⅲ. Contents
The technologies to be developed in this study are based on the use of supercritical fluids (supercritical CO₂). The details of each technology are as follows.

1) Decontaminatin of acitinides
- Development of CO₂-philic surfactants for actinide extraction
- Development of processes for actinide decontamination

2) Decontamination of radioactive metal ions
- Development of CO₂-philic surfactants (chelating ligands)
- Development of processes for radioactive metal decontamination

3) Removal of contaminated metal coatings by emulsion
- Development of CO₂-philic surfactants for emulsion formation
- Development of processes for the removal of metal coatings

Ⅳ. Expected contribution
Using the technologies developed in this study, we can reduce the secondary wastes revolutionarily during decontamination processes. In the nuclear industry, this technology can be applicable to the decontamination of metal parts, dresses, filters, and contaminated soil and sludge. And we can apply the same technology to dry cleaning, semiconductor cleaning, optical parts cleaning, and the cleaning of parts of complex geometry. And the surfactants developed in this study will be very competitive because they are rare materials in the market.
