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.”

As part of the U.S. DOE Office of Fusion Energy Nuclear Data Needs program, we have continued assessment of the nuclear data needs for the development of fusion energy. We have identified and reviewed the high priority elements whose neutron emission data are needed for a near-term fusion ignition facility and fusion power reactor designs for demonstrating the scientific and engineering feasibilities of fusion energy. We found that most of the elements identified here are lacking experimental data from 6 to 15 MeV except hydrogen, lithium, beryllium, and copper. A list of high priority dosimetry cross sections was developed that includes some 29 reactions, including 6 reactions recommended by the plasma diagnostic group of PPPL. Of these 29 reactions, 18 cross sections were chosen to be included in the ENDF/B-VI dosimetry files. The activation cross sections needed for elements to be used in the near-term ignition device and future power reactors were compiled. These cross sections were prioritized according to their activation levels and half-lives of their activation products. All these cross sections are going to be included in the END/B-VI activation files.
