低活化铁素体/马氏体（RAFM）钢，例如，F82 H是聚变包层的主要候选结构材料。在众多的包层方案中，水冷陶瓷增殖包层由于其结构紧凑，与传统轻水堆中使用高温水作为冷却剂的技术相兼容，是一个很有吸引力的方案。对于氚增殖，有必要通过控制冷却水中的氢和氧而不是化学物质来管理F82 H的腐蚀。因此，需要了解氧和氢对腐蚀性能的影响，用于包层设计。研究了F82 H钢在高温氢水中的腐蚀行为。根据腐蚀试验的结果，可以推测，氢气的加入预计不会显著改变流动加速腐蚀（FAC）。与此相反，发现与在空气中室温下的疲劳试验相比，在高温水中的断裂循环次数减少。
Reduced activation ferritic/martensitic (RAFM) steel, e.g., F82H, is the leading candidate structural material for fusion blanket. Of many blanket concepts, the water-cooled ceramic breeder blanket is an attractive concept because of its compactness and its compatibility with the technologies which using high-temperature water as coolant in conventional light water reactor. For tritium breeding, it is necessary to manage the corrosion of F82H by controlling not chemicals but hydrogen and oxygen in the cooling water. Understanding the effects of oxygen and hydrogen on corrosion property was therefore required for the blanket design. This work aims to investigate the corrosion behavior of F82H in high-temperature water with hydrogen added. Based on the results of the corrosion test, it is speculated that hydrogen addition expected no considerable change of the flow-accelerated corrosion (FAC). In contrast, it was found that the number of cycles to fracture was decreased in the high-temperature water in comparison to the fatigue test at room temperature in air.
