Based on the fundamental materials engineering, the strategic outlook of new metallic materials is important. Currently, considering the international competitiveness and environmental harmony, it is necessary to develop advanced steel manufacturing technology with high efficiency and low environmental impact. In the energy industry, nuclear materials technology, particularly the severe accident countermeasures technology is closing up as a problem which Japan should wrestle with. To address these problems, we have paid a lot of attention to the advanced refining and casting technology to produce functional materials in high quality. In addition, the development of durable materials for the severe accident in nuclear reactor plant is underway in our laboratory.
