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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

Calculations are made of 2.5-MeV neutron yields via D-D reactions from various beam line components, including beam targets and a neutralizer gas cell, and of x-ray generation from accelerator columns in deuterium beam injectors of various energies from 40 to 200 keV, with accelerator powers ranging from 2 to 20 MW per beam line. The calculated neutron intensities from the neutral beam injector systems for present and future fusion research are in the range between 1011 and 1013 n/s and warrant biological shielding in most cases, even for low duty cycle operation. X radiation from the accelerator columns becomes a health physics concern only for injectors with energy higher than ∼100 keV.
