项目摘要

Thermal conductivity is an important parameter influencing the performance of variety of materials. Laser Flash Analyzer can provide us with the accurate data on thermal diffusivity and conductivity of materials in a wide range of temperatures. At present, similar equipment is not available at the universities in Canada. The requested equipment is necessary in several different areas of the research outlined by the applicants; this includes innovative safe nuclear fuels, thermal stress effect on the failure of Zircaloys and pipeline steels, the thermal properties of nanomaterials, solid catalysts used in the chemical reaction studies, thermal conductivity of photoconductor alloys, thermal protective clothing and consumer products, the thermal conductivity of membranes used in liquid-to-air energy exchangers, the thermal conductivity of materials used in building envelopes, thermal conductivity and thermal diffusivity of the soils and the studies of thermal shock resistance of the novel synthesized materials at high service temperatures. At present, 13 research programs of 6 professors at the University of Saskatchewan were identified. This equipment will be essential for the applicants to realize objectives of their present and planned research. Here, it is necessary to point out that at present, the study of novel nuclear fuel is vital for the development of Canadian nuclear energy and the Laser Flash Analyzer will be also used to verify our ab initio calculations of thermal conductivity of thorium oxides with additives of UO2 and PuO2. This research is supported by Candu Industry Inc. that is involved in the design of Canadian thorium nuclear reactor. Such reactor will be safe and reliable source of thermal and electrical energy.

导热系数是影响各种材料性能的重要参数。激光闪光分析仪可以为我们提供材料在较宽温度范围内的热扩散率和电导率的准确数据。目前加拿大的大学还没有类似的设备。所请求的设备在申请人概述的几个不同研究领域是必需的；这包括创新的安全核燃料、热应力对锆合金和管线钢失效的影响、纳米材料的热性能、化学反应研究中使用的固体催化剂、光电导合金的导热性、热防护服和消费品、导热性液体-空气能量交换器中使用的膜的研究、建筑围护结构中使用的材料的导热性、土壤的导热性和热扩散性以及新型合成材料在高使用温度下的抗热震性研究。目前，萨斯喀彻温大学6名教授的13个研究项目已确定。该设备对于申请人实现其当前和计划的研究目标至关重要。这里需要指出的是，目前新型核燃料的研究对于加拿大核能的发展至关重要，激光闪光分析仪也将用于验证我们对添加添加剂的氧化钍导热系数的从头计算UO2 和 PuO2。这项研究得到了参与加拿大钍核反应堆设计的Candu Industry Inc.的支持。这种反应堆将成为安全可靠的热能和电能来源。
