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

Unlike renewables such as wind and photovoltaics, nuclear power is a carbon-free source of energy that offers reliable, dispatchable baseload energy. This unique characteristic makes nuclear energy an important component of the U.S. mix of carbon-free energy, and thus, a major contributor to achieving the goals laid out in the Paris Agreement. However, the current fleet of nuclear power plants are being outpriced by other energy sources, such as natural gas. One contributor to the high cost of nuclear is the outdated concept of operations. The current fleet of nuclear reactors employs the same concept of operations they started with over half a century ago. Idaho National Laboratory’s (INL’s) Human Factors Engineering (HFE) team under the U.S. Department of Energy’s Light Water Reactor Sustainability Program is engaged in helping the nuclear fleet modernize their control rooms. The goal is to transform nuclear power plant operators’ perceptions to improve efficient and safe plant operation. A major component to successfully transforming an aged control room with advanced technology is to use a design philosophy that guides the modernization effort. This paper discusses design philosophy and the role it plays. Also discussed is the initial approach to design philosophy and adherence to safety and regulatory requirements. Last, a brief discussion of how INL’s HFE team plans to implement a design philosophy that can be used industry wide.
