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

CEA/Valduc has developed a Thermal Cycling Absorption Process (TCAP) experimental device dedicated to the study of the separation of hydrogen isotopes and particularly to the recovery of tritium from low concentrated mixtures (tritium molar fraction < 6%). Simultaneously an original and efficient dynamic simulation tool has been developed in collaboration with PROSIM Company. After a brief description of the TCAP process device developed and the establishment of the modelling approach adopted, a deeper understanding of the complex TCAP behavior is lighted on through some simulation results. Then, a sensitivity analysis of the TCAP operating parameters on its global performance and particularly on the tritium contamination in the head flow is presented. Finally, all these results are applied to propose an optimized operating sequence for the recovery of tritium from low concentrated hydrogen mixtures.
