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.”

An in-depth nuclear analysis has been performed for WILDCAT that is a conceptual design of a commercial tokamak reactor utilizing a catalyzed deuterium-deuterium (D-D) fusion fuel cycle. Comparisons are made with the deuterium-tritium-fueled STARFIRE design in order to identify the salient features of D-D tokamak reactor designs. Since WILDCAT does not have to breed tritium, the blanket and shield system can be optimized to have a thinner inboard extent (∼0.8 versus 1.2 m for STARFIRE) leading to more efficient use of the toroidal field. The nonbreeding blanket concept of WILDCAT can also be utilized for substantial enhancement of the system energy multiplication (2.02 versus 1.14). These benefits help to overcome the reduced fusion reactivities and lead to a 60% more efficient blanket in terms of power generation. The outboard blanket and shield'system has been designed for personnel access within 24 h after reactor shutdown and uses as much as possible materials that are not resource limited and that have lower activation. Ninety percent of the materials in WILDCAT can be recycled within 50 yr after their discharge from the reactor.
