米国アルゴンヌ国立研究所の開発した高速炉と乾式サイクル施設を統合した統合型高速炉は受動的安全性，核不拡散性，放射性廃棄物の減容化において優れた核燃料サイクル方式である。またこのシステムは福島第一原子力発電所事故で生じた燃料デブリの処理に適用可能な技術と考えられる。実際にこの技術を使った場合，デブリ処理に要する時間，施設の安全性，建設コストを試算するとともに今後の技術的課題などの技術的可能性を検討した。
In order to obtain optimized forging forming process parameters, multi-objective optimization strategy of process parameters based on response surface method (RSM) was put forward. Taking strain uniformity and forming force of large-scale arc-shaped forging as the evaluation index, the analysis model of combining fini…
High frequency dielectric spectroscopy has been used to investigate the dielectric behavior of the pure as well as the aqueous solutions of 2-ethyl-1-hexanol at 270 and 300 K. It was found that the strength of Debye peak decreases systematically with increasing concentration of water. This behavior has been explained…
The effects of twin boundary spacing and angle between loading axis and twin boundary on the mechanical behavior of nano-twinned Fe under the uniaxial tensile load were studied by molecular dynamic simulation. The results indicate that the yield stress of nano-twinned Fe increases with the increase of twin boundary sp…

A detailed local analysis of the impact of water coverage on the density of surface states in In 0.5 Ga 0.5 As surface nanostructures is reported by spectroscopy monitoring the surface conductivity at the nanometer-scale.
Die Untersuchung des Ermüdungsverhaltens von Asphalt erfolgt im Rahmen dieser Forschungsarbeit anhand von Spaltzug-Schwellversuchen. Um den Zusammenhang des Ermüdungsverhaltens und des Hohlraumgehalts zu ermitteln, wurden Proben mit unterschiedlichen Hohlraumgehalten hergestellt und durch die Betrachtung der Asphalt-M…
we studied the mechanism of original n-and p-type "intrinsic" organic films 8-Hydroxyquinoline aluminum (Alq 3 ) and N, N'-bis-1-naphthyl-N, N'-diphenyl-1, 1'-biphenyl-4, 4'-diamine (NPB) via using molybdenum trioxide (MoO 3 ) as a p-type dopant. It is found that the conductivities extracted from "holes-only" devices…
The IPMCs with various thicknesses were manufactured by a hot-pressed method and their actuations in terms of tip force and displacement when being reused with different treatments were investigated. Three selected treatments are no treatment, treatment in deionized water or 2M NaCl solution. To achieve the great tip…
Dense composites of silver and Sc-stabilized ZrO 2 (Ag-ScSZ) are manufactured from ScSZ sub-micrometric particles coated with silver using Tollens' reagent. A composite with 8.6 vol % of silver exhibits metallic conductivity of 186 S cm −1 and oxygen flux of 0.014 μmol cm −2 s −1 at 600°C for a 1-mm thick membrane whe…
One of the factors that determine reliable operation of fuel elements in a nuclear reactor is maximum temperature of fuel pellets. This paper presents the computational study results of the effect of the pellet’s central hole on its maximum temperature when using different types of fuel.
回転ディスク電極は，回転速度を変化させることによって電極近傍に向かう物質輸送量を制御することができるため，酸化還元反応の機構解明や燃料電池の触媒評価などに利用されてきた．一方で，回転ディスク電極を材料合成の反応場として利用した例は，有機，無機問わず，数例しか報告されておらず，研究の拡充が必要である．そこで本研究では，回転ディスク電極を用いてアニリンの電解重合反応を行い，電極上に生成するポリアニリン膜の構造制御法の可能性について検証した．その結果，ポリアニリン膜は回転ディスク電極の回転速度の増加に伴い，表面構造が平滑化され，また，膜の緻密化が達成されることがわかった．このように回転ディスク電極は電解重合膜の構造制御を実施する上で，極…
イアコーンサイレージ（ECS）給与が，肥育牛の増体性および産肉性に及ぼす影響を検討した．黒毛和種去勢牛を，濃厚飼料の可消化養分総量（TDN）として40％相当をECSで代替した飼料を給与した区（ECS区）および市販濃厚飼料給与区（対照区）に各6頭ずつ配置し，10～27ヵ月齢まで肥育して増体性と産肉性を調査した．その結果，ECS区の体重および増体量（865kg, 0.93kg/日）は，対照区（790kg, 0.83kg/日）を上回り，TDN要求量はECS区が対照区よりも少なかった（P<0.05）．枝肉重量やバラの厚さはECS区で対照区よりも良好であったが（P<0.05），肉質や肉の理化学的分析値に差は認められなかった．このように，肥育…
Three dimensional nanostructured silicon based electrodes are promising for high capacity anodes in lithium ion battery. Though the specific capacity of silicon is very high compared to the conventional graphite anode, its large volume changes in cycling results in poor cycle life, which eventually restricts Si use in…
