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.

In order to make proof of the recovery of hydrogen isotopes from a liquid lithium (Li) blanket, we experimented the recovery of deuterium (D) dissolved in Li by means of yttrium (Y) metal at 300°C. In the experiment, 160 wppm D dissolved in Li was removed down to 1 wppm by means of the Y trap maintained at 300°C under fluidized Li conditions. The ratio of the final-state D concentration dissolved in Li to the initial one is defined as a removal efficiency, and the removal efficiency was found to be in proportion to the D concentration remained in Li. In addition, judging from its dependence on D concentration remained in Li, it was found that the removal efficiency is well consistent with the secondary-order reaction process and the removal efficiency was correlated to a function of contact time.
