Securing stable energy sources to establish the affluent society where people can live in comfort is now an important theme. For Japan where resources are scarce, the use of "nuclear power" which can generate great energy from a small quantity of nuclear fuel is essential. To meet this expectation, we have succeeded the research results attained by Mitsubishi group over many years and have participated in the business of manufacturing highly reliable nuclear fuel.
Moreover, in addition to the research and improvements of existing technology, we have also pushed forward the research and development activities of new technology to obtain an even more excellent supply of nuclear fuel. We will continue to make efforts to supply high-quality and cost effective nuclear fuel on safety-first philosophy in order to support people and industry toward a better future.
