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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

An alternate method to that of representing the drop size spectrum by a mean drop diameter in an iodine removal analysis of the containment spray system is presented. A discrete drop size distribution, which is obtained from a fit of a continuous distribution function to the drop size spectrum observed for the nozzles employed in the spray sys tem is used. A model for the calculation of the changes in this distribution due to drop coalescence and condensation of steam on the spray drops is derived. The results obtained from this analysis show that consideration of the drop size spectrum, condensation, and coalescence in the analysis of the spray system does not degrade the iodine removal effectiveness calculated for a typical Westinghouse reactor containment.
