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.”

Borate waste is the main liquid waste generated by nuclear power plants (NPPs). Vitrification is conceptually attractive because of the potential durability of the final product, the flexibility of the process in treating a wide variety of waste streams, and the economy of large volume reduction. The vitrification of borate waste from NPPs, including the glass formulation and product characterization, is examined. The Minimum Additive Waste Stabilization (MAWS) concept was utilized to design the glass formulation. The glass formulation named SL-1, which can incorporate 45 wt% of waste oxides, was selected. The SL-1 glass has good chemical stability, the melting temperature is 1000°C, and the viscosity of molten glass is ~5.0 Pas at 1000°C. The borosilicate glass form could satisfactorily solidify borate waste with high volume reduction.
