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.

Photochemical techniques are used for the mutual separation of lanthanide elements. By emitting light from an ultrahigh-pressure mercury lamp to a nitric acid solution that contains fourfold mixtures of lanthanide elements (neodymium, samarium, europium, and gadolinium), (NH4)2SO4, and isopropyl formate, neodymium, samarium, and europium are photoreduced and form Ln2+ sulfates, while gadolinium is not photoreduced and does not coprecipitate. When lanthanum is introduced instead of gadolinium, lanthanum coprecipitates along with neodymium, samarium, and europium. These results are explained by photolyzing Nd-Gd and Nd-La systems for comparison, and the difference in precipitation behaviors between these two systems is explained by the differences in ion size of these elements. Photolysis is also performed for a Nd-Am system. Am3+ is carried along with neodymium and coprecipitated. As a way to decrease the amount of americium carried along with neodymium, americium is photo-chemically oxidized by emitting light from a deuterium lamp as well as from a mercury lamp. The fraction of americium carried with neodymium decreases with the use of this technique. This result is also explained by the differences in ion size of these elements.
