[en] As a clean, green and efficient energy form, nuclear power is a good energy choice for China with a large population, rapid development and huge environmental pressure. In the post-Fukushima era, nuclear power has returned to rational development. Chinese government has formulated and promulgated regulations for risk assessment of social stability before approval of construction projects to ensure the implementation of the people's right to know, participate and supervise. However, there are still many problems in the depth, breadth and form of public participation in the construction of China's nuclear power projects. The main reasons are unclear subjects of public participation responsibility, inadequate publicity of public science, inadequate publicity of information, inadequate channels, unfavorable response to network public opinion, lack of public opinion response plans, inaccurate positioning of public participation and so on. In order to promote the smooth progress of China's nuclear power projects and ensure that the public's right to know is guaranteed, we should first do a good job in the top-level design of public communication in nuclear power; secondly, establish a tripartite information disclosure mechanism among the public, enterprises and the government; thirdly, construct multiple participants and various forms of communication; and finally, guide the network public opinion in the era of all-media.

[en] The author introduced a micro-controller-based CTS communication interface in nuclear logging, which provided convenience for the overhaul and regulation of the logging tool in CTS communication system. The use of micro-controller simplified the hardware structure of the interface, made the soft structure more rational and the whole system more flexible to control

[en] The new analyzing method and software and applications of inelastic spectra from carbon/oxygen spectrometry log is reported. Inelastic γ-ray spectra (256 channels) obtained by NaI(Tl) detector were analyzed quantitatively based on standard inelastic spectra, the methods to calculate the ratio of elements yields and new ratio of C to O and of Ca to Si are obtained. The yield ratio of C to O and the weight ratio of C to O and the atoms ratio of C to O were found, and the corresponding ratio of Ca to Si were found simultaneously by using the new analyzing method. The difference-value of the atoms ratio of C to O between 100% oil saturation and 100% water saturation in sandstone with 35% porosity is greater than 0.33. The difference-values between oil and water increase by a factor of 60%. In addition oil saturations curves changed with the depth were calculated. (authors)

[en] Nanoindentation-induced deformation and fracture of thin polystyrene (PS) films on glass substrates were characterized using visible-light microscopy and atomic force microscopy (AFM). Two film thicknesses, 2 and 3.5 μm were studied. It was difficult to induce delamination in the 2-μm film while the 3.5-μm film delaminated easily under indentation loads of 150 mN and higher. AFM cross-section analysis of the deformation and fracture geometry revealed that the ratio of the delamination radius to contact radius was between 3 and 4. Analysis of the fracture surface on the glass side indicates that substrate cracking acts as a trigger for initiation and propagation of interfacial cracks. Crack-arrest marks and process-zone marks were also observed by AFM imaging. The interfacial fracture toughness, or practical work of adhesion, was evaluated following two methods based on the indentation-induced delamination and a process-zone analysis. The fracture toughness was found to be approximately 0.6 J/m² for the 3.5-μm PS film on glass. AFM examination of the glass surface after indentation also showed fine flow lines around the indentation impression, indicating plastic deformation of glass

[en] The structural and magnetic properties of the two sources deposited Fe/Pd superlattices were studied. The samples were prepared by keeping the thickness of Pd layers d_Pd at 30 A and varying d_Fe from 5.7 to 56 A. The reduced saturation magnetization of Fe/Pd superlattices, σ_s increased with the decreasing of d_Fe, this was due to the polarization effect of Pd. The effective thickness of polarization effect was found as about 10 A at 0 K. The temperature dependence of magnetization followed Bloch T^3/2 law in the range of 7 - 300 K and the spin-wave stiffness constant B increased with the decreasing of d_Fe. The Curie temperature, T_c, decreased with d_Fe. The ⁵⁷Fe conversion electron Moessbauer spectrum illustrated that the polarization effect existed among the layers, and there were no magnetic enhancing effect and 'dead layer effect' on the Fe atoms at the interfaces

[en] The surface and structural properties of tungsten after cumulative helium bombardments have been investigated using molecular dynamics simulations. Helium atoms at 80 eV were injected into tungsten (0 0 1), (1 1 0) and (1 1 1) surfaces. The retention and distribution of helium atoms, the formation and growth of helium clusters and the surface evolution of tungsten substrates are found to be influenced by surface orientations and temperatures

[en] Molecular dynamics simulations were performed to study the interactions between low-energy (⩽100 eV) helium (He) projectiles and helium bubbles pre-existing near tungsten (W) surfaces. It is observed that with increasing bubble size, the reflection coefficient of the He projectiles was reduced, and the channelling effect that could be observed with no pre-existing He bubble was depressed. The He projectiles can be captured by pre-existing He bubbles and also knock He atoms out of the bubbles. The spatial distribution of the single He atoms, including both the slowed-down projectiles and the knocked-out He atoms, was extracted. The single He atoms were found distributed around the bubbles in a region with the width of 3–5.5 in lattice lengths of W. Although the results were obtained for the interaction of He projectiles with isolated He bubbles pre-existing in W, they suggest that the reflection and retention status of He projectiles would change during the irradiation of high flux/fluence He on W surfaces due to the change of He bubbles coverage near W surfaces. The results can be coupled with Monte Carlo modelling in conditions closer to that in experiments of high flux/fluence He bombardments on W surfaces.
