Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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

In the cooling water system (CWS), being infrastructure for large research facility, one of the important issues is the operation reliability, and then the minimizing of operation and maintenance costs. For optimum design, we studied the cooling loops for pulse and continuous operations of clients, volume and inside piping structure of storage tanks, two-step heat exchanger, safety devices and energy conservational operation of the CWS. During commissioning, the flow rate shortage due to increase of pump head by rise of client pressure drop was resolved as the operation of a stand by pump. The unexpected water pressure hunting occurred at an ion cyclotron ranges of frequency (ICRF) inlet port was stabilized by exchange of the starting system of motor and transfer of a constant flow rate valve from the water outlet port to the inlet port of the ICRF. We confirm that a polishing system, a first neutral beam injection cooling loop and a plasma facing component baking system can be stably operated in the upgrade step of clients. To improve the coefficient of performance and stability of operation in chiller, we will develop the new header, decreasing the gap of inlet temperature of cooling towers.
