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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

At the L-2M stellarator, in the electron cyclotron resonance heating regime, the processes of plasma self-organization were studied in different successive phases of plasma confinement during the facility shot. It is shown that in the phase of initial plasma heating, because of the absence of plasma-wall interaction, the canonical pressure profiles of the electronic component are not formed. In the quasi-stationary phase, the forming pressure profiles are close to the canonical one, and the energy loss is somewhat higher than in the phase beginning immediately after switching off the microwave heating pulse. After turning off the microwave pulse, the self-organization processes form the canonical pressure profiles of the electronic component in plasma, which ensure minimal energy loss from the plasma. In this case, the total power of energy losses from the plasma is proportional to the cube of the plasma energy.
