Abstract

Academic interests in ionic liquid (IL) technologies have been extended to the nuclear industry and the applicability of ionic liquids for processing radioactive materials have been investigated by many researchers. A number of studies have reported interesting results with respect to the spectroscopic and electrochemical behaviors of metal elements included in spent nuclear fuels. The measured and observed properties of metal ions in TBP(tri-butyl phosphate) dissolved ILs have led the development of alternative technologies to traditional aqueous processes. On the other hand, the electrochemical deposition of metal ions in ILs have been investigated for the application of the solvents to aqueous as well as to non-aqueous processes. In this work, a review on the application of ILs in nuclear fuel cycle is presented for the purpose of categorizing and summarizing the notable researches on ILs.

이온성 액체 기술에서의 학문적 연구들은 원자력 산업으로 확대되어 왔으며 많은 연구자들에 의해 방사성 물질의 처리에 이온성 액체의 활용이 연구되어 왔다. 다수의 연구들에 의해 사용 후 핵연료에 포함되어 있는 금속 원소들의 분광학적, 전기화학적 거동에 대한 흥미로운 결과들이 보고되었다. TBP(tri-butyl phosphate)를 용해시킨 이온성 액체에서 측정되고 관찰된 금속 이온들의 물성들은 전통적인 수용성 공정에 대한 대안 기술 개발을 유발시켰다. 한편, 수용성 및 비수용성 공정에서의 활용을 위해 이온성 액체에서 금속 이온의 전기화학적 전착이 연구되었다. 본 연구에서는 이온성 액체 연구에서 주목할 만한 내용들을 분류하고 정리하여 핵연료주기에서 이온성 액체의 활용에 대해 고찰하였다.
