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.

During 35 years of operation of the Savannah River Site (SRS) there have been a small number of inadvertent tritium releases to the atmosphere. After detection of the releases by stack monitors, field crews were dispatched to determine the concentrationoftritiumintheenvironment The objective of the measurements was to verify environmental concentrations calculated by dose assessment models. Airsamplers were used to verify the concentration levels and tritium fonns during the plume passage. It was not feasible to take enough samples in the plume path to determine the two-dimensional disthbution of tritium concentration in the plume. However, the ground level disthbution was very well reflected in vegetation samples. Therefore, it is usually possible to determine plume shape, plume width, and the relative maximum concentration as the plume moves downwind from the vegetation samples. In eight of the nine releases studied, the monitoring data allowed comparison with atmospheric transport models.
