Advanced-ORIENT Cycle Project: Summary of Phase I Fundamental Studies

The Advanced Optimization by Recycling Instructive Elements (Adv.-ORIENT) Cycle strategy has been proposed as a basic concept for trinitarian research on the separation, transmutation, and utilization (S, T, & U) of nuclides and elements on the basis of the FBR fuel cycle. Working in this direction, validation of the principal separation methods and related safety research were performed from 2006 through 2011 as the first phase. The separation scheme was composed of four ion exchange (IXC) steps and one catalytic electrolytic extraction (CEE) step. The fundamental technological aspects are summarized as the Phase I program.
