Abstract

Some Breeding Blanket concepts in nuclear fusion reactors contemplate the use of eutectic Pb_84.3 Li_15.7 (PbLi) because it simultaneously acts as Tritium (T) breeder (part of the reactor fuel) and neutron multiplier. For a proper reactor operation and control, the exact knowledge of PbLi composition, including impurities and ⁶Li isotope concentration is required, since it notably influences its properties (corrosion action, T production capabilities and T solubility, among others).

Here, we show the capabilities of ion beam analysis (IBA) techniques to accurately determine both of these issues. To do that, we combine nuclear reaction analysis (NRA) and particle induced X-ray emission (PIXE) to quantitatively characterize the C and O concentrations, the isotopic concentration of ⁶Li, and the medium weight impurities concentration for commercial PbLi samples after exposure to environmental conditions for different times (0.5–15000 h).

用离子束分析同时表征PbLi中O、C、6Li和中重杂质浓度

核聚变反应堆中的一些增殖毯概念考虑使用共晶Pb84.3 Li15.7 (PbLi)，因为它同时充当氚(T)增殖剂（反应堆燃料的一部分）和中子倍增器。为了进行适当的反应器操作和控制，需要精确了解pbi组成，包括杂质和6Li同位素浓度，因为它显著影响其性质（腐蚀作用、T生产能力和T溶解度等）。在这里，我们展示了离子束分析（IBA）技术准确确定这两个问题的能力。为此，我们将核反应分析（NRA）和粒子诱导x射线发射（PIXE）相结合，定量表征了商业pbi样品在环境条件下暴露不同时间（0.5-15000 h）后的C和O浓度、6Li同位素浓度和中重杂质浓度。
