Neutron resonance absorption imaging was adapted to observe the Eu band adsorbed in the CMPO/SiO-P column for minor actinide recovery by extraction chromatography. Several wet columns were prepared by either light water or heavy water and compared with the dry column to evaluate the neutron transmission. The neutron transmission spectra showed that 45% was transmitted through the dry column while 20% and 40% were transmitted through the wet columns of light water and heavy water, respectively. The results indicated that heavy water is more applicable than light water to observe the Eu adsorption band in the CMPO/SiO-P column.

-P adsorbent for extraction chromatographyMiyazaki, Yasunori; Watanabe, So; Sano, Yuichi; Kofuji, Hirohide; Takeuchi, Masayuki; Ishigami, Ryoya*

Extraction chromatography has been employed to separate minor actinides (MAs) from spent nuclear fuel for the purpose of reducing environmental impact. In our strategy, the polymer-coated SiO particle with an extractant is packed in a column and utilized for group separation and/or isolation of the specific element (Am and Cm, for example) from high level liquid waste. The safety use of chromatography was assessed by irradiation to the adsorbent with He
beam and 
ray to simulate the high-level nuclear waste. In this study, we focused on a recently developed extractant TODGA and its degradation behavior on top of the SiO-P adsorbent was investigated by a similar experimental manner.

High-level liquid waste generated by reprocessing spent nuclear fuel is geologically disposed after vitrification, and partitioning and transmutation of minor actinide (MA: Am, Cm) is performed to minimize the volume and toxicity of radioactive waste. We have been developing extraction chromatography for selective MA partitioning. The calculation code that simulates partitioning behavior of ions is developed, but the chromatogram is not yet reproduced adequately. The resonance neutron imaging at J-PARC allows us to observe partitioning behavior of ions inside the column undestructively. The obtained diffusion and dispersion data is applied to upgrade the simulation code as well as increase of column partition property.
