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.

This month’s issue of Nuclear News focuses on supply and demand. The “supply” part of the story highlights nuclear’s continued success in providing electricity to the grid more than 90 percent of the time, while the “demand” part explores the seemingly insatiable appetite of hyperscale data centers for steady, carbon-free energy.
Technically, we are in the second year of our AI epiphany, the collective realization that Big Tech’s energy demands are so large that they cannot be met without a historic build-out of new generation capacity. Yet the enormity of it all still seems hard to grasp.
or the better part of two decades, U.S. electricity demand has been flat. Sure, we’ve seen annual fluctuations that correlate with weather patterns and the overall domestic economic performance, but the gigawatt-hours of electricity America consumed in 2021 are almost identical to our 2007 numbers.

The formation of palladium deuteride during the electrolysis of heavy water is analyzed. This process is accompanied by thermal effects, such as local overheating, which can induce restructuring of the electrodes. The overheating depends on the size of the palladium-deuterium (Pd-D) clusters and the time scale for heat conduction. With the radius of the octahedral site occupied by deuterium in the Pd-D face-centered-cubic (fcc) lattice being similar or greater than the penetration depth of the temperature field for a single reaction of palladium with deuterium, Ruckenstein and Petty's equation has been applied in the calculation of the local overheating. A value of ∼2350°C for the maximum average temperature rise has been calculated for the Pd-D cluster formation. Similar calculations for the TiD2 fcc structure show that overheating probably depends also on the kinetics of D2 absorption. The presence of these phenomena may play some role in the reproducibility of cold fusion experiments.
