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.”

We describe state-of-the-art simulations of weakly ionized low-temperature plasmas for modern technologies. Emphasis is placed on fluorocarbon plasmas for manufacturing microelectronic devices and plasmas of rare gases for excimer lamps. Electron kinetics plays a crucial role in these plasmas. We illustrate the specifics of electron kinetics in different types of gas discharges. We evaluate the availability and quality of electron collision cross sections (total and differential) for elastic collisions with neutral species, excitation of electronic levels of atoms and internal levels of molecules, as well as their effect on the electron distribution function (EDF) and plasma chemistry. Among the crucial data needs for simulations of industrial plasma sources are validated gas-phase chemical reaction mechanisms including electron-induced reactions and gas phase reactions among heavy species.
