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.”

A dual coolant Pb-17Li (DCLL) blanket concept has been selected as reference design for the ARIES-CS compact stellarator power plant study. This configuration is characterized by helium cooled first wall and ferritic steel structures, and a self-cooled breeding zone. Flow channel inserts (FCIs) made of silicon carbide (SiC) composite are placed in the PbLi channels, serving both as thermal and electrical insulator. The goal is to optimize the Pb-17Li inlet and outlet temperatures for high power cycle efficiency while accommodating the material temperature limits, providing reasonable flow distribution and maintaining an acceptable pressure drop.A numerical study of magnetohydrodynamic (MHD) flows in the poloidal channels that distribute the liquid metal in the breeder units has been carried out to assess the performance of such a concept with regard to the above mentioned goals and constraints. The analysis considers the electrical coupling between adjacent poloidal ducts and the influence of various parameters such as the electric conductivity of the SiC insert and the orientation of the magnetic field.
