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.”

Work has been done to assess the ability of electron cyclotron emission (ECE) measurements to resolve rotating magnetohydrodynamic (MHD) islands in the high-temperature plasmas of ITER. In ITER discharges the high electron temperature will cause relativistic broadening of ECE frequencies, significantly larger than experienced in current magnetic fusion devices. The broadening will result in spatial averaging of measured Te oscillations and hence a reduction of resolution. This effect is quantified by using a code that calculates the EC absorption and emission for an ITER scenario, and by using simulated Te data the reduction in amplitude is determined. It is found that the reduction is modest and that it should be possible to measure MHD islands of 1 cm and larger.
