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.

In a reprocessing plant, the various and many accidents identified related to mechanical processes, chemical processes, and storage facilities have to be assessed to know the total risk of the plant. To assess the individual risks of so many potential accidents efficiently and effectively, we have developed a simplified quantitative method called quantitative safety assessment (QSA), based on our experience in probabilistic risk assessment (PRA) for the Rokkasho Reprocessing Plant and with reference to the integrated safety analysis used in the United States for fuel cycle facilities. Our method not only includes such PRA features as quantifiability of the results and comparability of risk importance of the contributors to accident sequences but also offers the new features of simplified presentation and easy traceability. The designation of important safety structures, systems, components, and personnel activities is thus facilitated through the use of the results of this method. In this paper, the deployment of the QSA method is demonstrated using an example of a criticality accident in a plutonium partition process.
