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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

An analysis of the thermal balance of a fusioning plasma from a control system perspective has been performed. The requirements for stability and the response characteristics of the thermal balance have been evaluated. The results show that open-loop equilibria are characterized by restrictively narrow stable operating temperature regimes and generally poor system performance. Closed-loop proportional feedback using the fuel feedrate and injection energy can be used to extend the stable operating temperature regime and significantly improve the system response. Thus, high open-loop temperature overshoots without neutral beam injection can be reduced to acceptable levels at temperatures as low as 20 keV, with a decrease in the settling time to under 30 sec. With 75 keV injection energy, acceptable overshoot can be obtained at plasma temperatures as low as 10 keV, with the time-to-peak below 20 sec and settling times less than 30 sec. It is still difficult to simultaneously satisfy overshoot and speed of response requirements at low temperatures with low feedback fractions. Additional improvement is available using proportional-integral-derivative (PID) control.
