Nuclear security culture enhancement: the role of culture coordinators at Russian nuclear sites

In 2002, a Nuclear Security Culture (NSC) Enhancement Program with the mission to raise the level of the NSC at sites and facilities in Russia's nuclear complex was launched under the guidance of the Russian State Corporation “ROSATOM” and with support from the US Department of Energy. A Joint Working Group for NSC with both Russian Federation and US members was formed and charged with the design and implementation of the program. The program was implemented at sites and facilities on a pilot basis. Nine sites participated in the Pilot Project. The key program component was an establishment of Culture Coordinators (CCs) with the authority to coordinate and implement NSC enhancement activities at sites and facilities. The CCs have served as the force that has maintained the momentum of the Pilot Project and continuously steered the site NSC enhancement efforts. The contribution of the CCs in achieving the positive outcomes of the program cannot be overstated.     

基于粗糙集理论的军队代储应急物资品种选择

从军队对应急物资的需求特点及应急物资的特征属性出发,构建了军队代储应急物资品种选择的指标体系。在此基础上,通过部队调研和专家经验获得了一组军队代储应急物资品种选择的样本数据并形成了决策表,运用基于可辨识矩阵的属性频率约简算法对决策表进行属性约简,并对约简属性集进行属性值约简,提取出军队代储应急物资品种的选择规则。提取的规则简洁合理,能够为军队代储应急物资品种选择提供决策支持。

碳氢化合物的红外光谱识别

碳氢化合物红外光谱特征吸收主要为甲基、亚甲基等结构基团的振动吸收,特征性不强,但C—C主链红外光谱振动吸收能表达不同碳氢化合物的分子结构特征。应用碳氢化合物红外光谱指纹区谱图形貌特征,建立了根据C—C主链红外光谱识别碳氢化合物的方法。研究结果表明,采用指纹区提供的特征信息能够实现对不同结构碳氢化合物的识别,准确率高达99%,优于采用碳氢化合物甲基、亚甲基等结构基团的红外光谱振动吸收信息获得的识别结果。

Shock-induced reaction behaviors of functionally graded reactive material

In this paper, the ballistic impact experiments, including impact test chamber and impact double-spaced plates, were conducted to study the reaction behaviors of a novel functionally graded reactive material (FGRM), which was composed of polytetrafluoroethylene/aluminum (PTFE/Al) and PTFE/Al/bismuth trioxide (Bi₂O₃). The experiments showed that the impact direction of the FGRM had a significant effect on the reaction. With the same impact velocity, when the first impact material was PTFE/Al/Bi₂O₃, compared with first impact material PTFE/Al, the FGRM induced higher overpressure in the test chamber and larger damaged area of double-spaced plates. The theoretical model, which considered the shock wave generation and propagation, the effect of the shock wave on reaction efficiency, and penetration behaviors, was developed to analyze the reaction behaviors of the FGRM. The model predicted first impact material of the FGRM with a higher shock impedance was conducive to the reaction of reactive materials. The conclusion of this study provides significant information about the design and application of reactive materials.
