本文讨论了使用液体硅浸渍（LSI）碳-碳复合材料开发紧凑且廉价的热交换器，管道，容器和泵，能够在800至1100°C的温度范围内使用高压氦气，熔融氟化物盐和硫碘热化学制氢的工艺流体进行操作。LSI复合材料具有几个潜在的吸引人的特征，包括在接近1400°C的温度下保持几乎全部机械强度的能力，廉价且可商购的制造材料，以及碳-碳预制件的简单成形、加工和接合的能力，这允许制造高度复杂的组件几何形状。在短期内，这些材料可能被证明是有吸引力的使用与熔融盐中间回路的演示与气冷高温反应堆的氢生产。从长远来看，这些材料可以用于熔盐冷却的先进高温反应堆，熔盐反应堆和聚变发电厂。
This paper discusses the use of liquid-silicon-impregnated (LSI) carbon-carbon composites for the development of compact and inexpensive heat exchangers, piping, vessels and pumps capable of operating in the temperature range of 800 to 1100°C with high-pressure helium, molten fluoride salts, and process fluids for sulfur-iodine thermochemical hydrogen production. LSI composites have several potentially attractive features, including ability to maintain nearly full mechanical strength to temperatures approaching 1400°C, inexpensive and commercially available fabrication materials, and the capability for simple forming, machining and joining of carbon-carbon performs, which permits the fabrication of highly complex component geometries. In the near term, these materials may prove to be attractive for use with a molten-salt intermediate loop for the demonstration of hydrogen production with a gas-cooled high temperature reactor. In the longer term, these materials could be attractive for use with the moltensalt cooled Advanced High Temperature Reactor, molten salt reactors, and fusion power plants.
