在深入分析相关领域研究发展状况的基础上,提出了具有较好技术可行性的聚变高温制氢反应堆概念(称之为FDS-Ⅲ),包括具有先进等离子体物理和技术水平的聚变堆芯、先进高温锂铅包层(HTL)、可减少热流分布密度的“垂直靶板”偏滤器以及相应的功率转换系统。尤其是提出了HTL包层新概念,其特点是选用技术基础相对成熟的低活化铁素体/马氏体钢作结构材料,在锂铅流道中使用可耐高温的多层流道插件,实现约1000℃的出口温度,可应用于制氢。初步性能分析表明FDS-Ⅲ制氢堆及其包层概念具有较好的技术可行性。
Based on the in-depth analysis of the research and development in related fields, the concept of fusion high-temperature hydrogen reactor (called FDS-III) with good technical feasibility is proposed, including the fusion reactor core with advanced plasma physics and technology, Advanced High Temperature Lithium Lead Cladding (HTL), “Vertical Targets” divertor to reduce heat flux density, and corresponding power conversion systems. In particular, a new concept of HTL cladding is proposed, which is characterized by the use of a low-activation ferrite / martensitic steel of relatively mature technology as a structural material, a multi-layer flow channel insert that can withstand high temperatures in lithium lead flow paths, The outlet temperature of about 1000 ° C can be applied to hydrogen production. Preliminary performance analysis shows that the FDS-III hydrogen reactor and its cladding concept has good technical feasibility.
