Photonuclear data are required in the field for, e.g., shielding design of high-energy electron linear accelerator, high-energy -ray therapy, and non-destructive assay. This work aims at developing photonuclear reaction data file with a wide range of nuclides for more extensive use. In order to perform evaluation in the -ray energy up to 140 MeV, nuclear reaction model calculation code CCONE was used. The modified Lorentzian model was applied to describe giant dipole resonance. The resonance parameters were fixed by reproducing photoabsorption data. The quasi-deuteron model was also taken into account in this present code. The nuclear level density was adopted from Gilbert-Cameron formalism with Mengoni-Nakajima Fermi-gas model. The evaluated results were compared with the measured data, JENDL/PD-2004 and KAERI data and showed good agreements with the measured data. These evaluated data are planned to be included into the next photonuclear data file.

Neutron- and proton-induced evaluated nuclear data are required in a wide energy range for the design of accelerator applications. New evaluations are performed with recent progresses in the optical and pre-equilibrium model calculations. We also evaluated cross-sections for p + 
Li and p + 
Be which are highly requested from medical field. Our present high-energy nuclear data library, JENDL-4.0/HE, includes cross-sections for 132 nuclei up to 200 MeV. In this talk, we present the evaluation methods, evaluated double-differential cross-sections and results of benchmark calculations.

Silicon carbide is a candidate nuclear materials because of low-activation and superior irradiation resistance as well as perceived various characteristics inherently featured as prominent engineering ceramics and a continuous fiber reinforced composite has generally been developed due to brittleness of SiC itself. Of many material parameters for design, validation of high temperature durability at approximately 1000
C is essential. Understanding of anisotropy of woven composite strength is also very important. Besides, developing comprehensive model to predict composite strength by various modes with a limited data set. This study aims to summarize the features of fracture behavior by tensile, compressive and shear at elevated temperatures. With consideration of the prediction model, we finally obtain the high temperature strength anisotropy map.

JAEA continues to carry out the development of the ADS(Double-strata). Mutual separation of MA and Ln is important for the development of the partitioning process. The separation is particularly difficult, because they have the analogous chemical behavior. New reagent was synthesized and examined. The results of separation factors (SF) of Am against Eu are more than 25, SFAm/Cm = 5.5. The reagent is very stable chemically, high extraction capacity, fully miscible with hydrocarbon diluents, fast chemical kinetics, and following the CHON-principle.

The basic matrices were compiled structurally which contain transport and exposure processes in the surface environment. And the method was shown to construct the steady-state biosphere model by combination of the basic matrices. To confirm applicability of the method, a dry run of the biosphere modeling for the hypothetical site was conducted.
