Preface

This report, "Persistent Quest," is published annually to introduce the most recent activities of the Japan Atomic Energy Research Institute, JAERI, to the public. We hope it will be of interest to readers and wish that more interested readers would visit our home page (http://www.jaeri.go.jp) and peruse other technical publications of JAERI.
JAERI, an organization devoted to comprehensive nuclear energy research, was established in June 1956. Since then, JAERI has pioneered nuclear science and engineering by engaging in the most advanced research and development activities.
JAERI has steadily engaged in a wide range of research and development studies in the realm of nuclear energy and radiation applications, while promoting comprehensive research in advanced science including photon and synchrotron radiation science. Through these undertakings, JAERI has originated valuable contributions to nuclear technology and science and technology in general.
Moreover, JAERI has opened its extensive facilities, which include accelerators and test and research reactors, to researchers from universities and other institutions, both domestic and international. This promotes cooperative research and development in many varied fields.
At present, JAERI's major research efforts in the field of nuclear energy consist of, 1) studies of next-generation energy systems, 2) high-temperature reactor technologies through the development
of the High-Temperature engineering
Test Reactor, HTTR, and 3) participation in the International Thermonuclear Experimental Reactor project, ITER. Through these programs, JAERI is aiming to develop leading energy systems for the twenty-first century.
JAERI also engages in comprehensive, fundamental nuclear research, focusing on, 1) neutron science to elucidate the structure and functions of materials by promoting the High-intensity Proton Accelerator Project, 2) radiation applications such as ion-beam irradiation, 3) synchrotron radiation science using
the Super Photon ring 8GeV, SPring-8,
4) advanced photon science like the development of X-ray lasers, and 5) advanced computational science and technology. Thus, JAERI promotes research and development to expedite the progress of science and technology into the future.
Marking its 45th anniversary, JAERI is at the forefront in the domain of nuclear science and technology. We will continue our research and development efforts with the objectives of enhancing the quality of life of our society and gaining the understanding and trust of the public towards our efforts. Your further support and encouragement is highly appreciated.
