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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Notes from the 2023 NN Reference Section
This year marks the 25th year that ANS's Nuclear News magazine has published its Reference Section, which features a world list of nuclear power plants, maps showing worldwide plant locations, tables with information on U.S. plant renewals, and international data tables and graphics. What follows are interesting tidbits that Nuclear Newswire has picked up from this year's Reference Section.
From the Reference SectionFive power reactors started commercial operations around the world in 2022 and five more closed, leaving the total number of operable nuclear power reactors in this 25th Annual Reference Section at 434, the same as the year before. What’s more, that number is just one more than the 433 power reactors listed in the 1st Annual Reference Section back in 1999. But make no mistake, plenty has changed over 25 years. Read on.
Technical Session|Panel|Sponsored by RPD
Wednesday, November 16, 2022|8:00–9:45AM MST|Sonoran 8
Session Chair:
Friederike Bostelmann (ORNL)
Session Organizer:
Different methods are discussed in the literature to determine approximations for zone-wise inventory in pebble-bed reactors. Various challenges exist including the consideration of a mixture of pebbles at different burnups, different travel paths of the individual pebbles through the core, traveling of the pebbles through zones of different temperatures/flux/powers/spectral conditions, and more. The panel is intended to cover the latest status of these methods, to discuss pros and cons of the different methods, to highlight where experience showed that phenomena need to be considered or that approximations are sufficient.
