Professor / SUZUKI Tatsuya
Prof. Suzuki is specialist in nuclear and radiochemistry. He has been studying on isotope separation science and nuclide separation related with spent nuclear fuel and radioactive waste management. He is often absent from NUT on business trip. However, he is dealing with the student's question kindly and he is a student - minded supervisor.

Research Content

In our laboratory, there are mainly 2 kind of topics; Isotope separation and nuclide separation.
The isotope effects in chemical reaction is studied, and the application of these effects to isotope separations or enrichments are carried out for the nuclear related field; nuclear medicine, fusion fuel, and so on.
Nuclide separation from spent fuels or nuclear fuel debris generated from severe nuclear accidents(like FuKuShiMa accident) have been studying. Spent fuels and debris contain kinds of radioactive fission products (FP) and minor actinides (MA), Our aim of the above studies is a load reduction from radioactive waste into human environments by the suitable separation of FPs and MA. For the realization of this aim, the dissolution studies for spent fuels and debris through the chemical conversion by thermochemical reaction, and the nuclide separation by chromatographic separation using solid extractant are carried out.

Lithium isotope separation

A Day in the Lab

In our laboratory, we are conducting research on schedule decided by each student themself. Such as Literature research, design of experimental scheme, specific experimental progress, data analysis and reporting, there are also many opportunities to participate in the support work with companies, Japan Atomic Energy Agency(JAEA).Since many international students are enrolled in our laboratory,English ability will also be imperceptibly improved.
