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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

The Net-Zero Government Initiative set forth by the current administration invites national governments to achieve net-zero emissions by no later than 2050 from national government operations. As a result, the current US administration’s goal of meeting net-zero emissions in all federal infrastructure operations by 2050 has led to a push to deploy clean energy sources. The Department of Energy seeks to accelerate the deployment of advanced reactors through the Advanced Reactor Demonstration Program to increase clean energy options. This potential surge in deploying advanced reactors requires identifying any nuclear fuel and component supply chain issues. This panel will discuss how supply chain issues are being identified and resolved to support the deployment of advanced reactors to meet clean energy goals.
