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.

NDA funds Plutonium Ceramics Academic Hub with U.K. universities
The United Kingdom’s Nuclear Decommissioning Authority has announced that it will establish a Plutonium Ceramics Academic Hub with the Universities of Manchester and Sheffield. The announcement follows a decision by the U.K. government in January to immobilize the country’s inventory of civil separated plutonium at the Sellafield nuclear site, mitigating the material’s long-term safety and security risks.
