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

A safety evaluation of the Tritium Removal Facility (TRF), constructed at the Darlington Nuclear Generating Station site is presented. This assessment focusses on the principal hazards associated with the facility, and the role of safety features in mitigating the consequences of any release of tritium. Additionally, the hydrogen explosion and fire hazards have been examined in detail to provide the assurance that the consequences of co-location of the TRF, in close proximity (∼100 m) to critical structures of the station, would not jeopardize the safe operation and shutdown of the reactors following a failure at the TRF.
