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
Fusion Energy
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.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

Multiphase thermal-hydraulics, such as boiling flows, plays an important role in nuclear safety and reactor design. However, its understanding, facilitated by both computation and experiment, is still relatively modest as a result of complexities encountered in multiphase modeling and measurement. In this panel session, leading multiphase modelers and experimentalists will join in a discussion to identify current multiphase thermal-hydraulic challenges, and to propose new ideas on how to address those. Specific attention is paid to the synergy between modeling and experiment, and to the role that AI may play in the path forward towards safer and more efficient reactor design.
