   	Summary
   J1	Research on measures to strengthen nuclear nonproliferation and nuclear security
   	Integrated Support Center for Nuclear Nonproliferation and Nuclear Security	Policy Research Office	Head Office	Kazunori SUDA Tel:029-282-0495 E-mail: suda.kazunori@jaea.go.jp	Non-Radiation Worker	Other
   	In consideration of importance and necessity of enhancing nuclear nonproliferation and nuclear security, a post doctorial fellow is expected to conduct various researches and analyses on nuclear nonproliferation and nuclear security, including assesment of nuclear proliferation and nuclear security risks, measures to reduce such risks as well as how to manage such risks, and possible mechanisms to strengthen existing international frameworks for nuclear nonproliferation and nuclear security.
   J3	Study on feasibility and effectiveness evaluation for severe accident countermeasures
   	Nuclear Safety Research Center	Severe Accident Analysis Research Group	Tokai Research and Development Center Nuclear Science Research Institute	Tomoyuki Sugiyama Tel:+81-29-282-5253 E-mail: sugiyama.tomoyuki@jaea.go.jp	Non-Radiation Worker	Physics Chemistry Mechanics Material Applied Physics Computer and Information Other
   	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.
   J13	Research on Criticality Safety/Management of Damaged- or Molten-Fuel formed by Severe Accidents
   	Nuclear Safety Research Center	Criticality Safety Research Group	Tokai Research and Development Center Nuclear Science Research Institute	Kotaro Tonoike Tel:+81-29-284-3762 E-mail: tonoike.kotaro@jaea.go.jp	Radiation Worker	Physics Computer and Information Applied Physics Other
   	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.
   J14	Nuclear reaction and structure study for exotic nuclei
   	Sector of Nuclear Science Research Advanced Science Research Center	Research Group for Heavy Element Nuclear Science	Tokai Research and Development Center Nuclear Science Research Institute	Katsuhisa Nishio Tel:+81-29-282-5454 E-mail: nishio.katsuhisa@jaea.go.jp	Radiation Worker	Physics Applied Physics Mathematics Measurements and Instruments Other
   	Experimental nuclear physics programs dedicated to exotic nuclei such as neutron-rich, proton-rich and super-heavy nuclei will be promoted. Challenge to find a new phenomenon in nuclear structure, nuclear reaction and fission processes will be highly encouraged. Experiments will be carrieod out using JAEA facility and also other facilities inside and outside Japan to produce exotic nuclei and unique states in nuclei.
