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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

A model for inspection, and its application to a reprocessing plant of the Nuclear Fuel Services type, have been developed. Two possible means of diverting material are (a) diverting material within the uncertainty of the material balance and (b) falsifying data. Statistical tests are performed by the inspecting authority: In the first case, the inspector compares material unaccounted for (MUF) with a significance threshold, while in the second case, a sample of the reported data is compared with his own remeasurements. Both methods are combined, and the optimal control and diversion strategies are computed (for an assumed probability of a false alarm and the amount to be diverted).
