RADIATION-CHEMISTRY RESEARCH AT JAERI - PRESENT AND FUTURE POSSIBILITIES

The Takasaki Radiation Chemistry Research Estabishment(TRCRE) of Japan Atomic Energy Research Institute(JAERI) was founded in 1963 as the center for Research and Development of radiation chemistry in Japan. Using its large facilities for irradiation of gamma rays from Cobalt 60 source and electron beams from accelerators, the TRCRE has been contributed to R&D on technology for industrial application of radiation chemistry. In 1987, the TRCRE started the construction of the ion beam irradiation facilities to promote a new project "Advanced Radiation Technology Study using Ion Beams (ART project)". The ART project is intended to push forwarded with R&D on materials for space and nuclear fusion reactors, biotechnology and new functional materials using ion beams. Two ion accelerators (AVF cyclotron and Tandem type accelerator) are now under construction to be operational in summer of 1991, and other two accelerators (van de Graaff accelerator and ion beam implanter) are further scheduled to be installed in 1993. In this report, the present R&D activities using gamma rays and electron beams are first summarized, and the future program using ion beams is described.
