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.”

Four detection probes were designed with the PTA code package and fabricated to study energy deposition, temperature rise, and damage to plasma facing components from runaway electrons in the Advanced Toroidal Facility, Oak Ridge National Laboratory. The PTA code package is a unique application of PATRAN, the Integrated TIGER Series, and ABAQUS for modeling high energy electron impact on magnetic fusion components and materials. Two of the probes were made of stainless steel, one of graphite, and one of molybdenum. They were inserted one at a time on the magnetic axis of ATF during field ramps. Each probe had two thermocouples to measure temperature increases. One of the stainless steel probes had activation foils to detect photonuclear reactions. Analysis of the experiment concluded that runaways on the order of 10 MeV exist in ATF. Damage to the materials was in the form of melting and ablation. The graphite probe survived with less damage than the other probes.
