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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

The new experimental storage ring (NESR) is one of the new facilities planned for the Facility for Antiproton and Ion Research (FAIR) project. It is conceived as a versatile storage ring used for experiments with stored ion beams (up to 740 MeV/u for uranium beams) and for the deceleration of antiprotons from the injection energy of 3 GeV, which are subsequently extracted and used for experiments elsewhere.The planning of the shielding requires particular accuracy because rooms adjacent to the NESR are desired to be accessible at all times. Extensive shielding calculations have been done using the Monte Carlo code FLUKA. Calculations were performed separately for the different operation modes of the storage ring, as well as for the different parts of the facility. Because of the large shielding thicknesses required (up to [approximately]4 m), biasing techniques had to be employed. While the results of the calculations confirmed that the planned shielding is sufficient in most places, two areas have been identified where a reinforcement of the shielding is recommended.
