APPLICATION

ADS research in SKKU

Actinide Partitioning

Tetraoctyl diglycolamide(TODGA)

is the most promising extractant for the separation

of long lived minor actinides from High Level

Waste and has been investigated extensively for

Actinide Partitioning. [1]

Effect of diluent and ionic strength was investigated

on the extraction behaviour of La(III), Eu(III) and

Yb(III) with TODGA.

Mechanism of extraction of Ln(III) / An(III)/ U(VI)

using DGA-chromatographic resin from nitric acid /

perchloric acid was investigated thermodynamically.

TODGA based EXC resin is capable of remediation

of liquid waste emanating from nuclear fuel cycle

facilities dealing with Pu in the presence of 0.01M

perchlorate[2]. Structure of digycolamides

Thermal analysis for Be target design

Life Cycle Assessment for ADS

LCA is a useful tool to consider life cycle

time scale from various points of view [4].

Developed by United Nations

Environmental Programme (UNEP).

LCA for ADS :

One of the fundamental problems

in nuclear power is the MA burning for waste reduction. Partitioning and transmutation both have

to be correctly evaluated from the LCA.
