摘要 液态锂与低活化铁素体/马氏体钢(RAFM)的组合是早期ITER阶段测试毯模块(TBM)和早期DEMO毯的选择之一,也是迈向Li/V DEMO毯的中间步骤。本文对 Li/RAFM 毯进行了表征,并从中子学和相容性的角度与 Li/V 毯进行了比较。虽然从 Li/V 到 Li/RAFM 的改变会使局部氚增殖比 (TBR) 降低~0.1,但从氚自给自足的角度来看,随着中子屏蔽的增强,Li/RAFM 似乎仍然可行。 Li/V 和 Li/RAFM TBM 的氚生产率相似,表明 Li/RAFM TBM 很好地模拟了 Li/V TBM 的氚生产,因此适用于 Li/V DEMO 包层设计以及 Li/RAFM 包层。根据现有数据,当锂中的杂质含量较低时,V合金被认为与锂高度相容。 RAFM 与 Li 的新相容性实验显示,除了腐蚀损失之外,马氏体相也转变为铁素体相。然而,对于 ITER-TBM 条件,兼容性问题估计很小。本研究表明,在 ITER 运行的早期阶段开始使用 Li/RAFM TBM 对于开发 Li/RAFM 和 Li/V DEMO 包层具有重要意义。
Abstract Combination of liquid lithium with Reduced Activation Feritic/Martensitic Steel (RAFM) is one of the options for Test Blanket Module (TBM) in early ITER period and early DEMO blanket, as well as an intermediate step toward Li/V DEMO blanket. In this paper, characterization of a Li/RAFM blanket was carried out and compared with a Li/V blanket from neutronics and compatibility viewpoints. Although the local Tritium Breeding Ratio (TBR) will be reduced by ∼0.1 by the change from Li/V to Li/RAFM, Li/RAFM seems to be still feasible, with enhanced neutron shield, from the tritium self-sufficiency viewpoint. A similar tritium production rate for the Li/V and the Li/RAFM TBMs suggests that the Li/RAFM TBM simulates well the tritium production of Li/V TBM and thus will be suitable for Li/V DEMO blanket design as well as Li/RAFM blanket. Based on the available data, V-alloys are thought to be highly compatible with Li when the impurity level in the Li is low. New compatibility experiments of RAFM with Li showed transformation of martensitic to ferritic phase in addition to corrosion loss. However, the compatibility issue is estimated to be small for ITER-TBM conditions. The present study showed the significance of starting with a Li/RAFM TBM during the early phase of ITER operation for development of both Li/RAFM and Li/V DEMO blankets.
