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.”

To maximise the safety of the future storage of tritiated waste water a zeolite called Analcime is being developed as an alternative to 4A molecular sieve. Synthesis methods have been developed that can produce particles up to 180 microns in diameter. Measurements of the rate of isotopic exchange of Analcime loaded with T2O when immersed in H2O at 25°C produced half-lives (t½) of exchange of between 64 and 172 years. These rates are approximately four orders of magnitude slower than 4A molecular sieve and demonstrate the potential of the material for the long-term immobilisation of tritiated water.
