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 full scale experimental assembly for study of the hydrogen isotope separation by cryogenic distillation is described. The cryogenic column has the diameter up to 300 mm, height of 5,5 m and place in the vacuum jacket diameter of 1200 mm and height of 6,5 m. There is a possibility to change the mass exchange sections of the column with various packings replacing of sections with diameter from 80 to 300 mm. Circulation gas flow in the column is up to 10 kMol per hour. Hydraulic and separation characteristics of the mass exchange packings of various types were studied by using the next working mixtures: Ar-O2, o-p-H2, H2-HD-D2, HD-D2-DT. The best values of the height transfer unit (HTU) were obtained for the packing produced from copper wire and put through chemical treatment and plate type with a small distance between plates. HTU was equal respectively 5–6 cm and 7–8 cm. A set of experiments was carried out for the improvement and understanding of the problems connected with safety of detritiation plant, for example, the freezing of air on the cryogenic surfaces of the column when in the jacket the microcrack is formed during operation and et. al.
