ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.”

Several neutronic calculations have been made for a specific hybrid blanket design in order to evaluate the capability that a fissile zone offers to improve the tritium or fissile fuel production and the energy gain of a fusion blanket. Studies with different fissile zone thickness show the usefulness of thin fissile zones to get high tritium breeding rates. Better total material (tritium plus fissile) production requires thicker fissile zones. Comparisons have been made between the materials neutronic damage expected in a pure fusion blanket and in a hybrid one, with greater energy to damage ratios obtained for the hybrid. Also, greater energy and damage rates are obtained for harder spectra (more 14 MeV neutrons in source) because of the higher potential of 14 MeV neutrons to produce fission in the hybrid blanket.
