Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

The oxidation behavior of iodide ion (I−) was investigated in aqueous solutions under a high dose rate of gamma irradiation in the range of 0 to 10 kGy·h−1. In particular, we investigated the formation of tri-iodide ion (I3−), the pH change of the solution, and the behavior of iodine species after the irradiation. As the gamma dose and the irradiation time increased, both the formation rate and the amount of I3− correspondingly increased. While I3− is not present above pH 10 due to its disproportionation reaction even without gamma irradiation, with irradiation, I3− does not exist above pH 6.4 because the H2O2 acts as a reductant above pH 5.4. At relatively high concentrations of I−, I3− was the major oxidation species of the gamma irradiation. However, as the irradiation progressed, the concentration of I3− decreased gradually, and eventually, I2 was left as the only species.
