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.”

We report data on tritium permeation at 323 K and 373 K through annealed and single crystal copper for comparison with our earlier data on unannealed copper,1 and show that tritium transport along grain boundaries or other lattice defects controls the overall rate at 323 K in unannealed material. Measurements on unannealed and annealed gold foil also indicate the importance of defect transport, although with gold we could not reduce the defect concentration sufficiently to measure permeation through the metal lattice. We also include permeation data on aluminum, molybdenum, tungsten, beryllium, cadmium, iridium, lead, rhenium, and silver; all of these were probably dominated by tritium transport along lattice defects.
