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.

Pervasive penetration of renewable generation can cause instability in the energy infrastructure and thus require distributed and dispatchable backup clean energy generation and storage. For a stable distributed smart grid, nuclear power systems with integrated energy storage are needed. Many possible technology options exist for storing either the thermal energy from the nuclear plant or electricity from the turbine in the power cycle, each with advantages and disadvantages. The adoption of particular energy storage options is largely dependent upon the scale of energy generation, ease of integration, and the end-use. In addition to providing dispatchable electricity, other applications of energy storage systems include building heating-cooling, industrial process heat, charging electric vehicles, etc. This panel includes well-known experts in the field of energy storage and nuclear hybrid systems from industry, national laboratories, and academia to discuss the state of demonstration and development of energy storage technologies.
