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.”

Plasma disruptions infusion reactors lead to high-energy deposition for short periods of time, causing melting of the first wall. A two-dimensional transient computer model has been developed that, by solving the equations of motion and energy, predicts the depths and the motion of the molten layers in small beam simulation experiments. It is demonstrated that convective flows caused by variations of surface tension—due to changes in material chemistry and surface temperature—play an important role in determining the depth and flow intensities of the molten layers. The calculated shapes and depths of the molten layers for Type 316 stainless steel have been compared with available experimental results and found to be in good agreement.
