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.

In case of accidental activity releases to the atmosphere, meteorological parameters have a strong influence on the radiological impact to the population. This influence is treated separately and is presented in the form of normalized dose statistics. It is shown that activity deposition on the ground constitutes the predominant exposure pathway and that, consequently, precipitation situations lead to the most critical consequences for the population. The analysis is carried out using a limited number of weather sequences. It is shown that the effect on the results is small if this number is reduced from 1750 to 115, provided that rain is adequately represented. Major differences are found for the maximum dose, but not for the average, the variance, and the fraction by which the threshold dose of acute health effects is exceeded.
