Japan Atomic Energy Agency (JAEA) is the only organization in Japan conducting
comprehensive research and development in the field of nuclear energy. Because
result of our research and development activities, various of industrially applicabletechnologies have been developed. Some technologies have a wide range ofapplications beyond the nuclear field. We have compiled a collection of technology
seeds for the industry and other external parties to use.
We hope that all parties involved in companies, universities, and research
institutes will use this technology seeds to understand our technologies andconsider joint research and technology transfer. It would be our greatest pleasure if
this collection of technology seeds could be of some use to you.
