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

Fueling the Future – Building on our Legacy
Nashville, TN|DoubleTree, Downtown Nashville
TopFuel 2025 is the leading international conference on new developments in nuclear reactor fuel performance. Held annually and rotating between Asia, Europe, and the US, this event gathers experts from around the world. The theme for the 2025 meeting is “Fueling the Future – Building on our Legacy.” It reflects our commitment to advancing nuclear fuel technology while honoring the achievements that have brought us to this point. This year, the conference will continue to emphasize Light Water Reactor (LWR) fuel performance while also expanding to include Advanced Reactor fuels. Attendees will have the opportunity to explore the latest innovations, share research, and collaborate on the future of nuclear energy.
