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.”

Simplified cost-scaling relationships are employed to identify the key economic drivers for fusion power systems. These economic drivers are examined in the context of compact reactor design trends. On the basis of this examination, four areas are identified as being critical paths in the development of compact designs. Two areas are physics in nature and concept dependent. These are the scaling dependence of energy confinement and the limitations on beta. Two areas are technological in nature and generic. These are the development of first-wall materials capable of operating at high wall loading (>5 MW/m2) and with useful lifetimes (∼1 yr) and maintenance approaches compatible with high availability and first-wall replacement times of ∼1 yr.
