Welcome to the
Our laboratory was first established in 2007 at KAIST.
The main thrust of our research activities is concerned with questions
on nuclear waste disposal and spent nuclear fuel issues. Current
efforts focus on better understanding the mechanisms of chemical
reactions in the fields of environmental radiochemistry, actinide
chemistry in aqueous solutions, and electrochemistry in molten salts.
For the safety assessment of nuclear waste disposal, we are studying
thermodynamics and kinetics of radiochemical processes, chemical
speciation, oxidation/reduction reactions, interface interactions,
colloid genesis and stability in geochemical environments. These
are fundamental for elucidating the fate and transport of radionuclides
in geochemical environments.
On the other hand, for recycling spent nuclear fuel and thus reducing
the amount of high-level radioactive waste, a pyrochemical process
in molten salts are under development. It is based primarily on
electrochemical methods such as electrolysis or electrorefining,
or electroreductive extraction in a molten salt solvent at high
temperature.However, there are still critical shortages of thermodynamic
properties of radionuclides in molten eutectic salts. This research
area is also included in our research program.
