Funasaka Lab. The study of glass matrix for vitrified waste in advanced fuel cycle.
It is necessary to develop the glass matrix with excellent environ-mental properties for high-level vitrified waste in advanced fuel cycle. As first step, the purpose of this study is to elucidate the relation between the structure and the redox reaction of metal ion in glass. By focusing on the basic reaction of oxygen states in glass (O0 +O2- → 2O-), we aim to elucidate the reaction between those kinds of oxygen and FPs in metallic ion with the results of NMR and EXAFS.
 
Harada Lab. Nuclear data are highly required to be improved for the study of innovative nuclear systems making possible nuclear transmutation of radioactive wastes. To meet the requirements, precise measurement methods will be developed using innovative radiation measurement and computer simulation technologies. Experiments will be performed at J-PARC, JRR-3 etc. Applications of the precise measurement methods are also studied.  
Motobayashi Lab. Using fast beams of radioactive isotopes (RI), we experimentally study the behavior of nuclei far from the stability valley and the nuclear reactions involved in elementsynthesis in the universe. At RIKEN, the new facilities of "RI Beam Factory" have been completed, and we are now in the position where studies of nuclear structure and astrophysical nuclear process can be greatly advanced by exciting unstable nuclei, which otherwise cannot be created, and measuring their gamma- and particle decays. We also plan to study nuclear reactions for transmuting long-lived nuclides.  
Ishihara Lab. Our study on material properties of graphite and ceramics based on the microstructure is a very important research from the view point of the high-performance material development as well as understanding of material behavior for advanced reactors, such as high-temperature gas-cooled reactors. Several material models considering the microstructure, such as grains and voids, are proposed for the quantitative understanding of the macroscopic properties. The irradiation behavior of the materials based on the microstructure change is also being studied by both experimental and analytical approaches.  
Ueno Lab. The research of our group focuses on the study of nuclei themselves, whose knowledge is important for their applications. Recently, anomalous properties of radioactive isotopes (RIs) have been discovered in the region of nuclei far from the beta-decay stability line. Based on the technique of experimental nuclear physics, we have conducted a research on their nuclear structure using the accelerator facility in RIKEN. In particular, we conduct R&D studies for the production of spin-oriented RIs, and apply the technique to the measurement of spin-related observables, such as nuclear moments.
