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 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. 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.”

Temperature dependence of oxide layer formation on hydrogen isotope retention in stainless steel type 316 was studied by TDS and XPS. The shape of TDS spectrum was clearly changed by the oxide formation temperature. The chemical states of iron, chromium and oxygen were also evaluated by XPS. The surface oxide layer was composed of iron and oxygen and the contribution of chromium was quite low. The ratio of oxide layer on stainless steel increased as increasing the annealing temperature. The deuterium retention trapped by the oxide layer, which corresponded to the desorption temperature of 600-800 K, was governed by the ratio of oxide layer, especially iron hydroxide. All of the iron was not oxidized and the saturation ratio of iron oxide to pure iron existed in the stainless steel. It was concluded that the saturation of deuterium retention trapped by the oxide layer was controlled by the amount of iron oxide in the oxide layer.
