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.”

This paper presents a method for quick determination of plasma shape and position in a tokamak. It is based on relating the plasma shape parameters to multipoles of the external poloidal magnetic field along the midplane. The technique can therefore be used for time dependent studies of the plasma in an electromagnetic environment in lieu of requiring an MHD calculation at each time interval. We obtain simple curves relating the plasma shape parameters to the magnetic multipoles and use standard schemes for determining plasma major and minor radii. The method is compared with actual free boundary MHD calculations.
