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.
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

U.S. reactor technologies to be featured at IAEA conference
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.

The effort to perform transient (TR) testing of nuclear fuel and materials in the United States took an important step in 2017 with the resumption of operations at the Transient Reactor Test (TREAT) Facility at the Idaho National Laboratory. As part of this restart effort, a U.S. Department of Energy–funded grant was tasked with developing a set of computational and experimental benchmarks for prior TR activities in order to assess the capabilities of historically developed codes used to provide the safety case for experimental design and evaluation. One subset of tasks in this project was the development of an experimental facility—the Transient Reactor Test Loop (TRTL) Facility—that would emulate a pump-driven flowing water loop that would be implemented at the TREAT Facility for TR testing of light water reactor fuel. The TRTL Facility was designed and developed at Oregon State University and began operations testing in 2017. Empirical data produced by this new experimental flow loop was benchmarked against a set of codes that represent the standard for use in industrial [Reactor Excursion and Leak Analysis Program–Three Dimensional (RELAP5-3D)] and regulatory [TRAC/Reactor Excursion and Leak Analysis Program (RELAP) Advanced Computational Engine (TRACE)] settings. The findings from those benchmarking activities from the TRTL Facility and the comparisons with the established safety codes are presented here.
