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

The experimental industrial plant for hydrogen isotope separation on the basis of the methods of chemical isotope exchange between water and hydrogen and water electrolysis (CECE process) is under operation in Petersburg Nuclear Physics Institute. The large-scale studies of hydrogen isotope separation have been ongoing at this plant since 1995. The plant is also used for reprocessing tritium heavy water waste; several tons of reactor quality heavy water have been obtained. The EVIO-4 code allows one to predict the concentration profile in the column under parameter changes. The calculation results are in compliance with the experimental data. The 18,000 hours experience gained during the plant operation shows the high efficiency of isotope separation by CECE process and allows us to regard this process with considerable promise for the industrial use, in particular, for water purification from tritium.
