Outline Activities
I am studying on nuclear materials especially nuclear fuels and radioactive wastes. For new nuclear fuels, our group are developing sol-gel method to fabricate cermet fuels, ceramic in metal matrix, which will be used in LWR, FBR and ADS. For waste management, our group is researching dissolution of glass waste, sorption of radionuclides on natural minerals and migration of radionuclides in the minerals.

Cement can be used to immobilize and solidify radioactive iodine by fixing it in the form of the iodate ion in the mineral ettringite. Because the half-life of 129I is 15.7 million years, radioactive wastes that contain 129I require disposal by burial deep underground. In the disposal of such wastes, compacted bentonite is used as a buffer material as well as the disposal of high-level radioactive wastes. Because there is a concern that radioactive iodine could leak from disposed wastes by diffusion through compacted bentonite over a long period, the release behavior of iodine from ettringite was examined by means of electromigration studies in compacted bentonite. Most of the calcium and iodine is retained within the structure of iodate-containing ettringite (IO3-AFt), even if the chemical form of iodine changes from iodate to iodide ion as a result of reaction with ferrous ions. However, acid produced by precipitation of ferric hydroxide might destroy the structure of IO3-AFt in cementitious materials and cause release of iodine. It might therefore be necessary to adopt measures to prevent intrusion of acid or ferrous ions into cementitious wastes containing radioactive iodine..

Se is redox-sensitive, and its oxidation state varies from -2 to 6 depending on the redox conditions and pH of the solution. Large quantities of ferrous ions formed in bentonite due to corrosion of carbon steel overpack after the closure of a repository are expected to maintain a reducing environment near the repository. Therefore, the migration behavior of Se in the presence of Fe in bentonite was investigated by electrochemical experiments. Na2SeO3 solution was used as tracer solution. Dry density range of bentonite was from 0.8 to 1.4 ×103 kg/m3.
Results indicated that Se was strongly retained by the processes such as precipitation reaction with ferrous ions in bentonite. Se K-edge X-ray absorption near-edge structure (XANES) measurements were performed at the BL-11 beamline at SAGA Light Source, and the results revealed that the oxidation state of Se in the bentonite remained Se(IV)..
