High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

Corrosion of ferritic-martensitic steel (FMS) Gr. 91 was performed in static Pb-15.7Li melt at 450 °C for up to 3000 h. Preferential grain boundary corrosion along with a homogeneous dissolution was observed. In addition, Al2O3 was coated to prevent the surface recession of FMS. Al2O3 was deposited on FMS using an electron-beam evaporated physical vapor deposition. The as-coated layer was crystallized through a heat-treatment at above 950 °C for 2 h. The alumina coating layer was very stable and effective to prevent the corrosion of FMS. Although Al2O3 was decomposed in 3000 h, the corrosion barrier survived up to 2000 h even in an oxygen-containing harsh environment.
