The Analysis of Mechanical Behavior for UMo/Al Dispersion Fuel on Different Fuel Volume and Burnup Xiao Liu1, a, Dazhi Qian1,b ,Zhihua Zhang1,a ,Bin Tang1,c 1 Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang, 621900, China aliuxiao6161@163.com, bqiandazhi@126.com, ctangbin_e@163.com Keywords: UMo/Al dispersion fuel, finite element, mechanical behavior Abstract.
Good thermal conductivity, small thermal expansion coefficient, stable structure.
Therefore, for convenience, the distribution of fuel grain in the fuel is considered as simple cubic cyclic structure.
The structure can be seen in figure 1.
This also indicates that the risk of rupture of fuel plate increases with corresponding fuel density rising. 3 Conlusion Basing on the characteristics of dispersion fuel structure, model for the cyclic unit structure between grains and between grain and cladding are established.

For example, ZnO can form rectifying electrical contact with silicon to form a solar cell structure.
One can observe two peaks corresponding to the (100) and (002) reflections of ZnO in the Wurtzite structure.
It is interesting to note that the improvement of crystal structure correlates with the I-V results and the higherrectification.
The post-deposition heat treatment at 400�C results in an improvement of the crystal structure along the caxis.

X-ray diffraction result showed that LiFePO4/C composite has an order olivine structure with space group of Pnma.
The structure and phase of the LiFePO4 were identified by a D/MAX 2500PC X-ray diffraction using Cu Kα radiation with a step size of 8°/min from 10° to 80°.
The as-prepared material reveal a single-phase LiFePO4 with an ordered olivine structure indexed by orthorhombic Pnma (JCPDS card No. 83-2092).
The result of XRD pattern shows that as-prepared material reveals a single-phase LiFePO4 with an ordered olivine structure and the presence of carbon does not influence the structure of LiFePO4.
The defect chemistry of LiFePO4 prepared by hydrothermal method at different ph values, J.

Conductivity measurements were carried out on Mn-doped PZT ceramics in order to investigate the changes in defect chemistry with annealing, by identifying the charge carriers such as lead or oxygen vacancies.
In a modified model, Eyraud et al (2007) [4] considered that donor and acceptor sites are not ions but rather vacancies (lead and oxygen ones) in the perovskite structure.
Defect dipoles may also form due to interaction of  OV with trace impurities e.g, Al and Fe in perovskite structure and thus presents a slight hardening effect in Mn-doped samples.
It is suggested that nitrogen annealing introduces oxygen vacancies which formed stable defect dipoles, which may align along the domain wall with applied field in perovskite structure and thus presents hardening effect in Mn-doped samples.
The constricted P-E loops may be due to presence of trace impurities e.g, Al and Fe in the structure, which may interact with oxygen vacancies.  OV .

Micro-alloyed steels are widely used in the manufacture of critical welded structures operating under extreme conditions of the North.
In both cases, in the heat affected zone, there are an overheating zone with a Widmanstetto structure and a normalization zone with a characteristic fine-grained ferritic-pearlite structure (Fig. 2).

The hollow structure possesses low density, high specific surface area and non-toxic [8].
However, the elongation at break was going down owing to the hollow structure of the filler.
Therefore, HSiO2 does not form a new chemical structure with PP and exists agglomerates.

For the individual grains from polycrystalline samples, the crystal structure was solved and refined using the SHELXTL program.
Introduction Many physical properties of polycrystalline materials are determined by the structure of individual grains of samples.
For the individual grains from polycrystalline samples, the crystal structure of TTF-CA was solved and refined using the SHELXTL program.
After the structure refinement for grains, the average R1 value was 2.06%.
It appears that multigrain approaches allow a structure solution of grains from polycrystalline samples at a level of resolution, such as single crystal diffraction.

A necessary and sufficient condition for the occurrence of this phenomenon is the charging with hydrogen the structure of the materials.
This should be related to the fact that niobium is an element stabilizing the local structure of Finemet-type alloys [14, 15].
Effectively, upon heating and progressively during a first step, nuclei or ultra-fine structure, which atom coordination take place within the “bulk” of the ribbon corresponding well to the Fe3Si cubic-type structure.
