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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

In the United States (U.S.) Department of Energy (DOE) Light Water Reactor Sustainability (LWRS) Plant Modernization pathway, the role of human factors engineering (HFE) continues to have an integral role in ensuring new advanced digital technologies that are part of the overall plant modernization strategy support optimized human-system performance and do not introduce new human failure modes. Regulatory guidance highlights human-system performance is a complex and multifaceted construct that requires a hierarchical set of measures including aspects of workload, situation awareness (SA), and task performance. Since workload, SA, and task difficulty are not directly observable, an accepted practice is to use subjective measures such as survey instrumentations. However, the time allotted for survey administration and post-scenario discussion during HFE activities can be significantly limited depending on operator availability and/or simulator availability. This paper explores the psychometrics of common survey instruments that measure workload, SA, and perceived task difficulty in nuclear power plant operator-in-the-loop studies with a goal of informing development of a consolidated survey instrument to reduce administration time. A set of exploratory analyses uncovered two principal components from the individual items combined from these surveys. A prototype survey instrument was thus developed as an early concept to illustrate how these two principals components could be expanded into a survey tool with fewer questions. A detailed discussion of the exploratory analyses and new prototype survey are discussed in this paper.
