About This Publication and the Outline Organization of JAEA
This publication introduces our latest research and development (R&D) results in each field. Each chapter presents theactivities of one R&D Directorate. As shown in the organization chart, the various R&D Directorates perform their activities
through R&D centers or institutes. Some of these consist of only one site, while others are located at two or more sites,
depending on their R&D activities. The R&D centers and institutes are located throughout Japan, as shown in the map below.
The following brief introduction outlines the research undertaken by each R&D Directorate in various R&D centers andinstitutes.

The Headquarters of Fukushima Partnership Operations is engaged in R&D to recover from the accident at theTokyo Electric Power Company, Incorporated Fukushima Daiichi Nuclear Power Station. Partnership operations for plant
restoration have set up Special Teams for Technologies Development at three centers of JAEA: the Nuclear Science
Research Institute, the Nuclear Fuel Cycle Engineering Laboratories, and the Oarai Research and Development Center.
These centers conduct R&D to restore the interior of the nuclear power plant. Fukushima Environmental Safety Center inthe Fukushima prefecture is conducting R&D concerning decontamination technologies to restore the environment,
develop outreach activities concerning radiation, and study measurement of radioactive materials in the human body bywhole-body counters.
The Advanced Nuclear System Research and Development Directorate is carrying out R&D aimed atcommercializing the fast breeder reactor (FBR) and its nuclear fuel cycle. The R&D of plant technology using theprototype fast breeder reactor MONJU is being undertaken at the Tsuruga Head Office (Fast Breeder Reactor Researchand Development Center), R&D for innovative FBR technology is being conducted at the Oarai Research andDevelopment Center, and R&D on manufacturing plutonium fuel and reprocessing spent FBR fuel is being conducted atthe Tokai Research and Development Center (Nuclear Fuel Cycle Engineering Laboratories).
The Geological Isolation Research and Development Directorate is carrying out multidisciplinary R&D aimed at
improving the reliability of geological isolation of high-level radioactive waste in Japan. A particular focus involves
establishing techniques for investigating the deep geological environment through research on crystalline rocks at theTono Geoscience Center and research on sedimentary rocks at the Horonobe Underground Research Center. At the Tokai
Research and Development Center, the focus is on improving technologies for designing disposal facilities and safetyassessment. In addition, work has been ongoing to develop a next generation knowledge management system based on theabove R&D activities.
The Fusion Research and Development Directorate is performing fusion R&D as a domestic agency of the ITER
project and an implementing agency of the Broader Approach (BA) activities. The procurement activity of the ITER
project, the upgrade of JT-60 to a superconducting machine as the BA activity, fusion plasma research, and R&D onJapan Atomic Energy Agency -Outline of OrganizationResearch and Development Directorates

Research Center project and the Engineering Validation and Engineering Design Activities of the International Fusionmaterial Irradiation Facility as the BA activity are performed mainly in the Aomori Research and Development Center.
5. The Quantum Beam Science Directorate is engaged in research using neutron facilities in the Tokai Research andDevelopment Center (Nuclear Science Research Institute) and the J-PARC Center. Work using electron beams, gamma
ray, and ion beam facilities is done in the Takasaki Advanced Radiation Research Institute. Research using lasers andsynchrotron radiation facilities is performed at the Kansai Photon Science Institute.
6. The Nuclear Safety Research Center is in charge of safety research for supporting national nuclear safety regulatory bodies
that regulate nuclear power plants, nuclear fuel cycle facilities, and radioactive waste disposal facilities. This work is doneat the Tokai Research and Development Center (Nuclear Science Research Institute) and at the Tsuruga Head Office.
7. The Advanced Science Research Center conducts pioneering research in basic fields of nuclear power science, mainly
through the Tokai Research and Development Center (Nuclear Science Research Institute) and the Takasaki Advanced
Radiation Research Institute.
8. The Nuclear Science and Engineering Directorate is engaged in key and basic research on various elemental
technologies that support the use of nuclear power. These efforts are carried out in the Tokai Research and Development
Center (Nuclear Science Research Institute) and the Oarai Research and Development Center.
9. The Nuclear Hydrogen and Heat Application Research Center conducts R&D on technology for the use of hightemperature heat supplied from naturally safe, high-temperature, gas-cooled reactors and technology for using this heat toproduce hydrogen. These studies are done in the Oarai Research and Development Center.
