    Non-Radiation WorkerNuclear Nonproliferation and Nuclear Security,
    In consideration of importance and necessity of enhancing nuclear nonproliferation and nuclear security, a post-doctoral fellow is expected to conduct various researches and analyses on nuclear nonproliferation and nuclear security issues, including how to utilize synergy effects when implementing technical measures on nuclear safeguards and security, risk assessment when utilizing such effects, and how to minimize such risks. The fellow is also expected to carry out studies on how to strengthen international regime on both nuclear nonproliferation and nuclear security.

    This research aims at development of analysis models and tools to improve evaluation techniques of severe accident countermeasures. One of the following tasks or that related to the tasks is carried out.
    - Source term analysis of Fukushima daiichi NPS accident using the SA analysis code THALES2/KICHE.
    - Analysis of fluid dynamic behaviors of core melt in containment vessel using the mechanistic FCI code JASMINE.
    - Analysis of thermal-hydraulic and deflagration/detonation behaviors of hydrogen in containment vessel or reactor building using the open CFD code OpenFOAM.

    It is important to establish both the cooling and the criticality control of fuel debris after the severe accident, such as the Fukushima Daiichi accident, where large amount of fuel is damaged and melts. It is difficult, however, to control the situation of fuel debris and the coolant flow path, which leads the difficulty in securing the subcritical condition. Thus, the evaluation of re-criticality risk is necessary. In this research, critical mass, kinetic parameters, etc. of fuel debris will be obtained by computation; and critical experiments to validate the computation will be studied as well.

    Experimental and theoretical studies of unstable nuclei and superheavy elements will be prompted. The research topics include nucler structure, nuclear reaction, and nuclear fission for nuclei far from the stable isotopes. In experimental programs, JAEA facilities and/or external facilities will be used to produce exotic nuclei. In theorey subjects nuclear structure and fission process will be studied by taking advantage of the JAEA supercomputer.

    The purpose of this reseasrch is to clarify the process of national consensus building by adopting social scientific approaches, and refelct it to the formulation of development strategies and policy recommendations. Specifically, analyses are performed on obstructive factors in siting, maintaining and developing facilites facing similar problems even though such facilites are required for maintaining the stable livelihood of the people, as well as the transition of fast reactor development at home and abroad. These analyses can cralify the process of consensus builing including roles of relevant entities to study what actions should be taken.

    Radiation WorkerRadiation,
    To realize advanced safety control of H2 generated in severe accidents in nuclear facilities, subsequent decommissioning and waste management, radiolysis of aqueous solution systems and radiation damage of materials such as adsorbents, catalysis and debris will be studied experimentally and analytically. Then their data will be applied to construction of analysis code for the H2 behavior, and to development of technologies for the reduction and prevention of accidents originated from the H2 generation.
