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.

NRC engineers share their expertise at the University of Puerto Rico
Robert Roche-Rivera and Marcos Rolón-Acevedo are licensed professional engineers who work at the U.S. Nuclear Regulatory Commission. They are also alumni of the University of Puerto Rico–Mayagüez (UPRM) and have been sharing their knowledge and experience with students at their alma mater since last year, serving as adjunct professors in the university’s Department of Mechanical Engineering. During the 2023–2024 school year, they each taught two courses: Fundamentals of Nuclear Science and Engineering, and Nuclear Power Plant Engineering.

India has proposed to develop and test the Lead-Lithium–cooled Ceramic Breeder Test Blanket Module (In-LLCB-TBM) in ITER. This concept, unlike some others, may need a high-performance ceramic coating on the inner wall to meet dual requirements such as high insulation to mitigate magnetohydrodynamic effects and a tritium permeation barrier to avoid tritium in the structural material. We deposit Er2O3 coatings using a direct-current magnetron reactive sputter deposition technique. As part of optimizing the coating from the application point of view, we carried out a series of deposition experiments. These included investigating the effects of substrate temperature in the range 165°C to 360°C, the effects of postannealing, and the effects of oxygen-to-argon gas flow ratio, keeping all other process parameters constant. Primarily, a densely packed film is required to grow in the most stable cubic crystal structure, with very high resistivity, in the range of gigaohm-centimeters to teraohm-centimeters. The results indicate that erbia films of thicknesses in the range 270 to 1000 nm are formed in amorphous, monoclinic, and cubic phases, where the cubic phase content is enhanced in a narrow window of the flow ratio at 360°C. Both crystalline phases seem to grow in a preferred crystalline direction. Post-vacuum-annealing at 500°C for 2 h largely transforms the monoclinic phase into the cubic phase.
