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.

First concrete marks start of safety-related construction for Hermes test reactor
Kairos Power announced this morning that safety-related nuclear construction has begun at the Oak Ridge, Tenn., site where the company is building its Hermes low-power test reactor. Hermes, a scaled demonstration of Kairos Power’s fluoride salt–cooled, high-temperature reactor technology, became the first non–light water reactor to receive a construction permit from the Nuclear Regulatory Commission in December 2023. The company broke ground at the site in July 2024.

2023 Nuclear and Emerging Technologies for Space NSTOR invitation
This year ANS launched a fully open access publication platform, Nuclear Science and Technology Open Research, which aims to provide a venue to host a wide range of article types, from full papers to brief reports to data notes, and more. Additionally, NSTOR features rapid, publish-before-review publication with the ability to revise and update articles as desired.
We warmly encourage NETS 2023 authors to submit an expanded abstract or paper (must be updated from the conference submission). Please take a look at our full list of article types to determine which one might suit your submission. Additionally, we welcome non-peer-reviewed submission of posters and slides. Follow this link or email nstor@ans.org for more information or to submit. Deadline: December 31.
Note: Submit by December 31 and receive a 100% discount on all publishing fees.
We look forward to hosting NETS in May 2023. The venue for this conference is on the west bank of the Snake River, which is one of America's great river systems. For those unfamiliar with Idaho Falls, it is a city of ~60,000 in eastern Idaho. This city has an airport serviced by Delta, American, United and Alaskan with approximately 10-12 flights daily to Seattle, Salt Lake City, Denver, Dallas and Phoenix. NETS 2023 will have a particular focus in a few different areas. One plenary session will be devoted to a historical look at the missions that were nuclear-enabled such as Voyager, New Horizons, Mars 2020, and with an eye towards the future, Dragon Fly. Another plenary session will focus on the future with a closer look at nuclear reactors such as the Advanced Test Reactor and the Transient Test Reactor at the Idaho National Laboratory and the reactor test bed being established for testing small modular and micro-reactors in the next few years. For those who wish to come early or stay an extra day or two to explore nature, two of the greatest national parks (Yellowstone NP and Grand Teton NP) are within a 2-hour drive and may be tempting. Come and experience Idaho Falls with exciting NETS 2023 involvement!
