水冷锂铅（WCLL）DEMO聚变堆的发展需要生产能够充当氚渗透屏障（TPB）的材料。在DEMO包层反应堆中，需要结构材料上的渗透屏障以将从Pb-17 Li或等离子体到冷却水中的氚渗透减少到可接受的水平（<lg/d）。由于先前进行的实验工作，最有希望的TPB候选者之一是A1基涂层。在欧盟范围内，一项大型研发计划正在进行中，以开发一种TPB制造技术，该技术符合结构材料要求，并能够生产性能可接受的涂层。研究的重点是化学气相沉积（CVD），热浸，热等静压（HIP）技术和喷涂（这也是为修复而开发的）沉积技术。最终的目标是选择一种参考技术，用于DEMO反应堆的包层和ITER测试模块的制造。这里总结了在四个欧洲实验室进行的活动。
The development of the water cooled lithium lead (WCLL) DEMO fusion reactor requires the production of a material capable of acting as a tritium permeation barrier (TPB). In the DEMO blanket reactor permeation barriers on the structural material are required to reduce the tritium permeation from the Pb–17Li or the plasma into the cooling water to acceptable levels (<1 g/d). Because of experimental work previously performed, one of the most promising TPB candidates is A1 base coatings. Within the EU a large R&D programme is in progress to develop a TPB fabrication technique, compatible with the structural materials requirements and capable of producing coatings with acceptable performances. The research is focused on chemical vapour deposition (CVD), hot dipping, hot isostatic pressing (HIP) technology and spray (this one developed also for repair) deposition techniques. The final goal is to select a reference technique to be used in the blanket of the DEMO reactor and in the ITER test module fabrication. The activities performed in four European laboratories are summarised here.
