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

This paper builds on previous work that characterized the nature of the nuclear power plant (NPP)–electric Grid system, the concept of Grid resilience, and the potential of current U.S. NPPs to enhance the U.S. Grid, integrated Critical Infrastructure, and societal resilience. The concept of a resilient nuclear power plant (rNPP) is defined. Two rNPP Key Attributes and Six rNPP Functional Requirements are presented. A preliminary discussion of some rNPP design features that could enable an NPP to achieve the Six rNPP Functional Requirements is presented, along with a preliminary discussion of some rNPP regulatory, siting, and economic considerations. Taken as a package, the Six rNPP Functional Requirements define an NPP performance envelope that extends the societal value proposition of nuclear energy well beyond that of traditional baseload electricity generation. The paper lays the foundation for exploration of high-value rNPP applications and for future rNPP conceptual design studies.
