Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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

Lithium adsorption on the surface of magnetite, lepidocrocite, and maghemite particles was studied at different pH values in LiOH and Li2CO3 solutions under redox conditions and temperatures relevant to the water chemistry of CANadian Deuterium Uranium (CANDU) reactors. Lithium adsorption on maghemite shows a different behavior than on lepidocrocite and magnetite. It is concluded that specific adsorption is the dominant adsorption mechanism on maghemite while lithium adsorption on lepidocrocite and magnetite is nonspecific. However, lithium intercalation into the spinel structure of magnetite and maghemite is also likely. The introduction of O2 reduces lithium adsorption on magnetite. The adsorption behavior of lithium on iron oxides is important to understand the lithium hideout and return in the heat transport system during shutdown and restart of CANDU reactors.
