Advanced Ceramic Structures and Coatings for Corrosion Protection and Thermal Insulation for Generation IV SCWRs

正如加拿大2008-2009年第四代能源技术研究和开发重点国家计划中所述，为堆芯内和堆外部件确定合适的化学物质和材料将是发展超临界水反应堆(SCWR)的主要挑战之一。根据现有的数据，目前还没有一种合金得到足够的研究来明确地确保其在SCWR中的性能。加拿大致力于SCWR系统国际开发的主要重点将是研发一种出口温度高达625摄氏度的压力管式反应堆。这项研究方案解决了识别和测试新型多孔绝缘材料的要求，这些材料是设计高效CANDU-SCWR燃料通道的关键部件之一。

As stated in the Canadian National Program on Generation IV Energy Technologies Research and Development Priorities for 2008-09, the identification of appropriate chemistry and materials for in-core and out-of-core components will be one of the major challenges for the development of the supercritical water reactor (SCWR). Based on available data, there is no single alloy that has currently received enough study to unequivocally ensure its performance in an SCWR. The primary focus of the Canadian effort toward the international development of the SCWR system will be R&D to develop a pressure tube reactor operating at an outlet temperature of up to 625oC. This research proposal addresses the requirement to identify and test new porous insulation materials, which are one of the key components in the design of high efficiency CANDU-SCWR fuel channel.
