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.
Educational Session|Panel|Sponsored by Business/Economic Performance
Tuesday, August 11, 2020|12:00–1:30PM EDT
Session Organizer:
Maria Hernandez (Duke Energy)
Track Organizer:
Timothy Schlimpert (MCR Group)
Knowledge Manager:
Amber Von Ruden (Exelon Corporation)
This session will review recent operating cost data to analyze the nature of current spending, evaluate trends in spending and identify those areas most likely to provide opportunities for improvement in the future. Maria Hernandez, Nuclear Corporate Finance Manager for Duke Energy and Timothy Schlimpert, Vice President, MCR Performance Solutions will complete and present the analyses. Supporting data is collected and provided for analysis by the Electric Utility Cost Group (EUCG); the only organization collecting robust industry cost data. All information is provided blinded to protect the confidentiality of all data contributors. For more on the EUCG visit: www.eucg.org
