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.

An investigation of iodine absorption on ion exchange resins in aqueous electrolyte solutions has been performed. For I- and I ions, the distribution coefficients are inversely proportional to the electrolyte concentration in solutions, whereas the adsorption of HIO with ion exchange resins is independent of electrolyte concentration in solutions. The mechanism of HIO adsorption is believed to be surface matrix adsorption rather than the ion exchange process. The distribution coefficients for HIO measured at both 20 and 56°C are nearly constant, whereas the coefficients for I- and I ions are approximately a factor of 100 smaller at the higher temperature. The distribution coefficients for I- ions in water are generally on the order of 104, which is approximately three to five times larger than that for I- ions. The half-time of the exchange reaction for I ions with the strong acid resin in water at 20°C is ∼50 s, compared to ∼90 s for I ions. Some experimental data obtained in an operating boiling water reactor have also been reported.
