Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

A test experiment to polarize tritium nuclei to develop a polarized deuterium-tritium (D-T) laser fusion concept is proposed in which a ferromagnetic complex with a high internal magnetic field is used to polarize tritium nuclei on physisorbed D-T molecules with an internal β-decay heat load in a D-T target. Heteronuclear hydrogen deuteride (HD) is used to conduct the measurements herein instead of as in typical D-T–based experiments. As proof-of-concept experimentation, the adsorption and desorption characteristics of HD are examined on Prussian blue ferromagnetic analogue Ni3[Fe(CN)6]2 at temperatures of 77 K and around 23 K. Nuclear magnetic resonance (NMR) analysis of the ferromagnetic complex-mediated adsorption of HD onto activated carbon pellets at 10 K is conducted step by step using a multilocular probe cell that had been simplified to give a single-tube probe cell. The resulting 1H NMR spectra are compared with 19F NMR spectra obtained for reference on a Kel-F probe cell wall. Slight differences between the calculated NMR frequency from the gyromagnetic ratio and the actually observed NMR frequency are also discussed.
