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 purpose of this technical note is to evaluate the discharged fuel of breed-and-burn (B&B) reactors. The discharged burnup in a B&B core can be high, and there is a concern that as decay heat increases, handling after a shutdown might be difficult. Because discharged fuels contain a number of plutonium nuclides, the potential for proliferation is also a concern. Moreover, radiotoxicity levels are an issue for geological disposal. As reference cores, two stationary wave reactor (SWR) cores proposed in our previous studies were used. The SWR is a special type of B&B reactor. Discharged fuels of the two SWR cores were evaluated by comparing them to a pressurized water reactor (PWR) and a fast breeder reactor. The discharged fuels of both SWR cores were not significantly worse than the reference PWR, even though the burnup was about 2.6 to 7.0 times higher.
