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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

The effort to perform transient (TR) testing of nuclear fuel and materials in the United States took an important step in 2017 with the resumption of operations at the Transient Reactor Test (TREAT) Facility at the Idaho National Laboratory. As part of this restart effort, a U.S. Department of Energy–funded grant was tasked with developing a set of computational and experimental benchmarks for prior TR activities in order to assess the capabilities of historically developed codes used to provide the safety case for experimental design and evaluation. One subset of tasks in this project was the development of an experimental facility—the Transient Reactor Test Loop (TRTL) Facility—that would emulate a pump-driven flowing water loop that would be implemented at the TREAT Facility for TR testing of light water reactor fuel. The TRTL Facility was designed and developed at Oregon State University and began operations testing in 2017. Empirical data produced by this new experimental flow loop was benchmarked against a set of codes that represent the standard for use in industrial [Reactor Excursion and Leak Analysis Program–Three Dimensional (RELAP5-3D)] and regulatory [TRAC/Reactor Excursion and Leak Analysis Program (RELAP) Advanced Computational Engine (TRACE)] settings. The findings from those benchmarking activities from the TRTL Facility and the comparisons with the established safety codes are presented here.
