    The main objective is to understand chemical and atomic properties of superheavy elements (SHEs) placed at the uppermost end of the Periodic Table. This theme will focus on the valence electronic structure of SHEs from the measurements of ionization-energy, electron spin, surface adsorption, ionic radii, redox potentials, and molecular formations. The subjects include development of the measuring system based on an "atom-at-a-time" method. These experiments will be performed at the JAEA Tandem Accelerator Facility.

    Structures and physical properties of materials from single-layer to bulk will be studied by using the advanced beams (neutron, positron and muon) produced at accelerator and reactor based facilities such as J-PARC. Those experiences are not required but high motivation for the researches are preferred.

    Studies on nano-fabrication and characterization will be performed for novel multi-functionalized materials. Molecular beam epitaxial (MBE), scanning tunneling microscopy (STM) and electrochemical methods will be used for the research (e.g. elucidation of surface reaction and structures of surface oxygen sensor in liquid metal for partitioning and transmutation technology).

    In order to reduce the burden of the geological disposal of high level waste (HLW), we are investigating partitioning and transmutation technology. The separation of minor actinides from HLW is particularly important since they have high radiotoxity and long half lives. In this study, the novel extractants which has high selectivity of americium and curium from high level liquid waste will be studied and evaluated applicability for practical separation process, and the minor actinide separation process from HLW will be developed with the novel extractant. The experiments using minor actinides and high level liquid waste will be carried out in glove boxes and hot cells.

    Reasearch on evaluation of meddle and long term soundness for nuclear industry materials in radiation environment will be conducted. Especifically, basic data on corrosion behavior was obtained by immersion test, electrochemical tests and so on under a wide range of environmental conditions taking into consideration the environment in Fukushima Daiichi nuclear power station (1F) where high radiation field was expected. We will elucify corrosion phenomena which can occur during the decommissioning of 1F.

    It is important to develop volume reduction and safety storage for a large amount of solid waste generated from the accident of Fukushima Daiichi Nuclear Power Station. Removal and recovery technology of radioactive material from the solid waste using subcritical water washing, volume reduction and immobilization technology of recovered material by inorganic solids like a functional glass are developed in this research.

    At Fukushima Daiichi, radionuclides in the contaminated water have been removed according to thier physicochemical forms. Posttreatment method for disposal of those radionuclides collected by various materials has yet to be decided. This study aims to develop effective posttreatment methods for mainly long-life anionic radionuclides for which few effective treatment methods for geological disposal are known. The posttreatment methods for them include selective sepatarion (accumulation), conversion to stable inorganic form, and subsequent solidification.

    It is widely known that microorganisms affect the environmental migration behavior of radionuclides in various stiations. This theme performs fundamental research on microbial influence on the chemical states of radionuclides, the response of microorganisms to radionuclides, and microbial influence on interaction amongradionuclides, minerals, and plants. This study aims to discover and elucidate novel phenomena.
