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.

An automated solution assay instrument (SAI) based on transmission-corrected gamma-ray measurements has been developed and installed in the Plutonium Processing Facility at the Los Alamos National Laboratory. The instrument was designed for rapid, nondestructive assay of plutonium process solutions over a wide range of concentrations (0.05 to 500 g Pu/i, with 10−4 to 5 g Am/ℓ) and for routine operation by process technicians who lack instrumentation experience. For a 25-ml sample, the precision is <0.8% for concentrations >30 g Pu/ℓ within a 1000-s assay and <1.0% for concentrations >4 g Pu/ℓ within a 2000-s assay. The results of test and evaluation demonstrate that the SAI is a reliable and accurate instrument for assaying plutonium process solutions.
