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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

Large-size nuclear power reactors are subjected to dynamic problems that can be formulated using modern control theory. The problem considered here is a power oscillation caused by the presence of a fission product, 135Xe, which is formed when the nuclear fuel undergoes fission. The application of control theory leads to a mixed boundary value problem. The presented method avoids the shooting by changing the direction of integration in the adjoint equations. Taking the steady state as the initial function, the method converges in a great parameter range. The method is formulated in general, but results are shown only for the one-dimensional case.
