In commemoration of the 15th Anniversary of the Modified Japan Research Reactor-3 (JRR-3), a symposium was held at Techno Community Square RICOTTY (Tokai-mura), December 4, 2006. The operators and users of JRR-3 reported their fruits in science and technology in the past and presented future plans. Dr. K. Sato, a former member of the executive director of Japan Atomic Energy Research Institute, presented a valuable episode in JRR-3 modification works. Mr. N. Kimura, director of "The Office for Quantum and Radiation Research, MEXT," and Emeritus Prof. Y. Endoh, president of "The Japanese Society for Neutron Science," expressed their sincere thanks for a large contribution to science and technology in these 15 years JRR-3 operation, and also their desire for the future contribution. Distinguished scientists reported their fruits in the various research fields at the JRR-3, such as developments of advanced neutron instruments, material sciences, structural analyses of protein focusing on hydrogen positions, water distribution in plants, structural analyses of soft materials and residual stress measurements. We presented the upgrading plan of the JRR-3 to increase the intensity of cold neutron beam to 10 times. This upgrading plan can create new world of science and technology. A desire for this upgrading plan was expressed by scientists and engineers. The consensus in the symposium was as follows. The Japan-Proton Accelerator Research Complex is suitable for experiments requiring high intensity pulse neutron beam. The JRR-3 is suitable for high accuracy experiments using continuous neutron beam. Therefore, both facilities are complementarily indispensable for science and technology using neutron. Total number of participants was about 230 from domestic universities and industries, etc. The lectures and research fruits presented in the symposium are summarized in this report.

The Department of Research Reactors and Tandem Accelerator is responsible for the operation, utilization and technical development of JRR-3(Japan Research Reactor-3), JRR-4(Japan research Reactor-4) and NSRR(Nuclear Safety Research Reactor) as well as Tandem Accelerator. The following services and technical developments were achieved in Japanese Fiscal Year (JFY) 2006: JRR-3 was operated for 156 days in 7 cycles and JRR-4 for 145 days in 37 cycles. They provided neutrons for research and development of internal and external users. (1) JRR-3 and JRR-4 were utilized through deliberate coordination as follows, (a) Neutron irradiations of 633 such as neutron transmutation doping of silicon, (b) Capsule irradiations of 2922 such as neutron activation analyses, (c) Neutron beam experiments of 5511 (cases*workdays). (2) According for the plan increasing cold neutron beam strength 10 times, Integrity of moderator vessel at liquid-hydrogen-evaporation events was confirmed by the stress analyses. Also, it was confirmed by optical tests that glass type carbon plates promising as radiation-resistant neutron guides possesses the same performance of glass plates, and irradiation tests of glass type carbon plates was prepared. (3) In Born Neutron Capture Therapy using JRR-4, an extended collimator that enable clinical trials for head-and-neck cancer were put into practical use. (4) In NSRR, pulse operations of 4 were carried out as planed, to experiment the high burn-up fuel of LWR. The capsule loading facility Type B was completed for to high- plutonium-content and high-burn-up MOX fuel. (5) Tandem accelerator was operated for 182 days to carry out all the scheduled experiments with heavy ions for internal and external users. The multi-charge ion injector in the high voltage terminal was moved to the other side in the terminal so that the beam stability was improved.
