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

The mass transfer parameters of Liquid Phase Catalytic Exchange (LPCE) column have been evaluated as a part of conceptual design study of a water detritiation facility for JET. Height of Transfer Unit (HTU), Height Equivalent to Theoretical Plate (HETP) and overall mass transfer coefficient (KG) were evaluated for tritium and deuterium isotopic exchange between gaseous hydrogen and liquid water using the LPCE column operated with the same three-isotope mixture. The HTU and KG were the same for tritium and deuterium. This indicates that mass transfer in gaseous phase and isotopic exchange reaction limit the overall mass transfer rate in the LPCE column. However, a deviation from this behaviour has been observed for the small water load to the column.
