Although JENDL-4.0 was released in 2010, the high-energy cross sections of about 40 FP nuclides were not re-examined due to the time limit. Gallium is one of such data which were not revised in the high-energy region. Considering the significance of gallium as semiconductor material, the present work was undertaken to evaluate the neutron cross sections of stable isotopes in the energy from 10
eV to 20 MeV. The statistical model code POD, which was based on the Hauser-Feshbach theory, was used to evaluate cross sections above several keV. Parameters required as input tithe POD code were determined by reflecting the latest knowledge on nuclear physics. As for the neutron optical model parameters, we used the values obtained by Kunieda 
using the coupled-channel method. The evaluated results reproduce existing experimental data very well.

Outline of International Nuclear Human Resource Development Program (Instructor Training Program: ITP), which is sponsored by MEXT, for Asian ten countries by JAEA will be reported. ITP consists of three major activities, i.e. Instructor Training Course, Follow-up Training Course and Nuclear Safety seminars. 16 years training activity from 1996 at JAEA and Asian countries has developed around 160 of instructors and more than 2,000 of trainees in Asian countries.

Actinides (Th, U, Np, Pu, Am, Cm) are important nuclides for the analysis of radioactive wastes from nuclear facilities. In order to achieve simple and rapid analysis of actinides, capillary electrophoresis-laser-induced fluorescent detection method (CE-LIF) is one of the potential candidates. In this study, new emissive probes of uranium suitable for CE-LIF were developed. The detection and separation of uranyl ions were examined using several new emissive complexing probes, each of which possessed a fluorophore and a different chelating moiety. Using acyclic tetradentate probes, the highly sensitive fluorescent detection of uranyl ions was successfully achieved. The detection limit of mid-ppt levels was determined.

Excitation functions of Pb(C,x) fragmentation reactions are measured in 10-400 MeV/u energy range and compared with simulation by PHITS (JQMD+GEM). Fragments within mass range 20-60 and those within 110-130 are underestimated by a factor of 10. This suggests reaction model not considered in conventional Monte-Carlo radiation transport simulation codes (e.g. percolation model) are necessary to reproduce production of fragments lighter or heavier than fission fragments.

For spent fuels cooling, sodium-cooled fast reactor has the ex-vessel fuel storage tank (EVST) and the spent fuel storage pool which have the huge amount of nuclear materials. This mainly reports the cooling characteristics of these equipments in case of the station black out due to the earthquake and subsequent tsunami.

In this study, measurement was conducted for the sliced MOX pellets containing 30% of Pu prepared by a conventional powder metallurgy technology. The thermal diffusivities of these samples were measured at temperature up to 2150 K with the laser flash method. Thermal diffusivities of the near-stoichiometric samples obtained in the cooling process were greatly lower than those in the heating process unlike measurement below 1770 K. On the other hand, they were almost identical for the sample of 1.946 in O/M. It was also shown that thermal diffusivity decreased with the temperature but increased with the O/M.
