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.”

The Tokamak Physics Experiment (TPX) is planned to develop the scientific basis for an economically competitive and continuously operating tokamak fusion power source. It has been designed to have steady-state operating capability, sufficient performance to produce reactor-like plasma configurations, and a flexible set of steady-state plasma controls. Active plasma control (e.g., current profile control, shape and position control, passive and active MHD mode stabilization, and toroidal rotation control) is a key to achieving steady stale tokamak operating conditions with enhanced beta and confinement, efficient current drive, high purity, and high reliability. Inductive scenarios and steady-state operating modes with current-drive have been studied to determine the system requirements for access and maintenance of advanced steady-state modes. Industry contractors have begun detailed engineering design of the superconducting magnets, vacuum vessel, and plasma-facing components.
