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 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. 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.”

Along with pellet implosions, the interior of an inertial fusion reactor will be exposed to intense and short pulse power fluxes, leading to materials ablation. Ablated materials will either collide with each other in the axis-of-symmetry region or be re-deposited elsewhere in the target chamber. The present work is intended to investigate the behavior of colliding ablation plasma plumes and that of materials re-deposition in hydrogenic atmosphere. Laser-ablation plasma plumes of carbon are set to collide with each other in a laboratory-scale experimental setup. Results indicate that carbon cluster ions are formed, including C2+ C3+ C4+ C5+ and C6+, some of which grow into aerosol in the form of micro/nano carbon structure. Also, it has been found that ablated carbon and hydrogen can form co-deposited layers with the H/C ratio, reaching the order of 0.1.
