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.”

ITER in-vessel components must be remotely handled and maintained due to their neutron activation. Components requiring regularly scheduled maintenance include the blanket shield modules, divertor cassettes and the various ancillary systems mounted in the vacuum vessel (VV) ports. Maintenance is predominantly performed by removing the component from the VV and transferring it to the hot cell facility where it is repaired or processed as waste. Component transfer, as well as remote handling (RH) equipment deployment, is performed with sealed transfer casks that are capable of connecting to the VV ports and hot cell while maintaining containment. An overview of the in-vessel remote maintenance requirements, techniques and equipment is presented.
