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

正如加拿大2008- 2009年国家第四代能源技术研究和开发优先项目所述，为堆芯内和堆芯外组件确定合适的化学物质和材料将是超临界水反应堆（SCWR）发展的主要挑战之一。根据现有的数据，目前还没有一种合金得到足够的研究，可以明确地保证其在超临界水堆中的性能。加拿大对SCWR系统国际发展的主要努力重点将是研发一种压力管反应堆，在出口温度高达625摄氏度的情况下运行。作为高效CANDU-SCWR燃料通道设计的关键部件之一，新型多孔绝热材料的识别和测试是本课题研究的重点。

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.
