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 formation of a plasma potential is experimentally investigated in a fully-ionized collisionless plasma flow along converging magnetic-field lines in the presence of a single ECR point. When the ECR occurs in the region of converging region, the potential profile is observed to be drastically modified. The resultant potential structure consists of a negative potential dip and a subsequent positive potential hump working as a plasma-flow dike potential, which persists in the steady state when the ECR point is located in a region of good curvature of the magnetic configuration. However, this potential structure temporally collapses when the ECR point is located in a bad curvature region. The phenomenon is considered to be caused by low-frequency flute and drift instabilities.
