The permeation of deuterium through coated stainless steel tubes containing liquid lithium-lead eutectic (Pb-17Li) has been studied and compared to measurements through tubes without the lithium compound. The measurements form part of an investigation into the effect of a potential tritium breeder material on permeation barriers for fusion reactors. Without the lithium-lead, CVD coatings reduced the permeation rate up to one order of magnitude, and the aluminised layer up to two orders of magnitude. A CVD layer was unaffected by the Pb-17Li whilst in the case of the aluminised tube, the lithium-lead completely removed the permeation barrier. The aluminised sample presented a large number of cracks and poor adherence to the substrate.
