- W1998942102 abstract "Abstract In order to evaluate the feasibility of selective sulfidization of uranium and rare-earth(RE) oxides, an analysis on ther-modynamic data, such as M-O 2 -S 2 phase stability diagram and changes of Gibbs free energy for sulfidization of uranium andrare-earth oxides were carried out. Comparing RE-O 2 -S 2 with U-O 2 -S 2 phase stability diagram at wide range of sulfur potential,UO 2 remains unreacted, while RE oxides are sulfidized. The Gibbs free energy change(∆G o ) of sulfidization of RE oxides islower than that of uranium oxides. Thus, the selective formation of RE sulfides is possible during sulfidization of RE and ura-nium oxides at lower temperature. CS 2 was selected as a sulfidizing agent, because it is a stronger sulfidizing agent than otheragents and reacts at lower temperature.Key words :Uranium, Rare-earth, Oxides, Sulfides, Sulfidization 1. 서론 미래형 핵연료 기술개발의 일환으로 원자력발전소에서 타고난 사용후핵연료의 재활용을 위한 건식처리에대한 연구가 활발히 수행되고 있다. 사용후 핵연료에는이산화우라늄(UO 2 ) 외에도 연소 중 핵분열로 생기는 여러 핵분열생성물 원소들이 불순물로 함유되어 있다. 이중 희토류 원소 (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd등, RE: rare earth)들은 중성자 흡수 단면적이 크기때문에 사용후핵연료 전체 중성자 흡수량의 약 50% 정도를 차지한다. 특히 핵분열생성물 중에서 Nd, Sm 및Eu는 중성자 흡수능이 매우 높다" @default.
