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 project, conceptual design of the fusion-fission hybrid energy reactors (FFHER) and related verifying experiments, was started in the framework of the National Magnetic Confinement Fusion Science Program of China in May 2010.Based on the current or slightly extrapolated ITER fusion science and technology and the well developed fission technology, fusion-driven sub-critical systems design was performed. We put forward the main concept of FFHER blanket with uranium alloy as fuel and water as coolant. The uranium can be natural uranium, LWR spent fuel or depleted uranium. FFHER can increase the utilization rate of uranium in a comparatively simple way to sustain the development of nuclear energy.We study the interaction among the fusion neutron and fuel to achieve larger energy multiplication and tritium sustainable, verify the creditability of physical design by the integral neutron experiments. With the combination research of this program and the following thermal hydraulic design, alloy fuel manufacture and nuclear fuel cycle programs provide the science and technology foundation for the future development of FFHER in China.
