Outline of Final Research Achievements

In this study, we have been focusing attention on the borate glasses in the way of new immobilization matrices by solidifying radioactive polluted water derived from the Accident at Fukushima Nuclear Power Plant of Tokyo Electric Power Company (TEPCO). In this exam, we have studied thermal behaviors of making borate glasses, and a possibility of making the borate glasses at lower temperature than existing have been suggested. And then, it was found that the addition of Zn to the borate glasses is possible to improve the water resistance. Moreover, it was confirmed that it is possible to immobilize nuclides and the spent adsorbents using the borate glasses.
