ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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 cumulative yields of fission products within the mass range of 83 to 119 and 123 to 158 have been measured in the epi-cadmium neutron-induced fission of 243Am by using an off-line gamma-ray spectrometric technique. Mass chain yields were obtained from the cumulative yields of the fission products by applying the charge distribution correction. From the mass yield data, the full-width at tenth-maximum of the light and heavy mass wing, the peak-to-valley (P/V) ratio, the average light mass <AL> and heavy mass <AH>, and the average number of neutrons <ν> were obtained. The mass yield data in the 243Am(n,f) reaction were compared with similar data in the 243Am(nth,f) and 243Am(n16.5 MeV,f) reactions to examine the role of excitation energy on the nuclear structure effect and P/V ratio.
