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.”

Blanket neutronics experiments were conducted for the development of the water-cooled pebble bed type ITER Test Blanket Module (TBM) using the Fusion Neutronics Source (FNS). Slab mockup assemblies based on the water-cooled pebble bed ITER TBM including water panels and/or a breeder pebble layer were irradiated by 14 MeV neutrons. After the irradiation, the amount of tritium produced in the diagnostic Li2CO3 pellets or breeder pebbles is measured by liquid scintillation counting method. The C/E ratios for the tritium production rate in those experiments are within 1 ± 0.05. A plan of the neutronics test on ITER-TBM and the neutronic diagnostics in the module are discussed. Micro fission chambers and compact activation foil transfer systems to be embedded in TBM are proposed for the neutron flux and neutron spectrum measurements, respectively.
