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.

This paper will demonstrate the potential of modern design for additive manufacturing by using computational fluid dynamics with design optimization. The Transformational Challenge Reactor Instrumentation and Control (I&C) Team has specifically requested that an instrumentation plane be designed for monitoring of the core-coolant-flow average temperature within ±5°C of the core outlet average temperature. However, because of systemwide constraints, this design space is allotted a pressure drop of only 0.5 psi. A successful design optimization study is discussed along with the thought process leading to the successful conclusion of an I&C plane with an average temperature of 497.3°C and a standard deviation of 1.03°C, all while maintaining a 3.38-kPa (0.49-psi) pressure drop across the outlet plenum.
