Fuel Cycle and Waste Lab (FCWL) endeavors to find out a solution for radioactive waste and spent nuclear fuel issues, arising from generation to disposal. Our lab interests lie generally in four major areas: 1) radioactive waste decontamination, 2) radioactive waste disposal, 3) spent nuclear fuel recycling, 4) spent nuclear fuel disposal.

Major research field

Radioactive waste decontamination, Radioactive waste disposal, Spent nuclear fuel recycling, Spent nuclear fuel disposal

Desired field of research

Research Keywords and Topics

Molten salt based electrochemical decontamination of radioactive metals (zirconium alloys, stainless steels, nickel alloys)
High degree separation of actinide elements from spent nuclear fuel using liquid metal electrodes
Chemical stability of radioactive waste including hazardous materials (e.g., heavy metal and organic solvent) in radioactive waste repository
Structural safety of radioactive waste disposal packages in normal and seismic conditions of a repository
