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.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

The technical feasibility of partitioning concentrated nitric acid intermediate-level waste (ILWC) solutions from the Purex process into a small volume of high-level waste and a large volume of low-level waste using sorption methods is demonstrated for 1-ℓ batches. Cesium-134 and 137Cs are selectively separated with a decontamination factor (DF) greater than 1 × 105 in a newly developed “suspended-bed” column filled with the microporous inorganic exchanger ammonium molybdophosphate. The 125Sb and the actinides and lanthanides with a 3+ valence state are retained with DFs between 40 and 1000 on metal oxides of antimony and manganese and on an extraction column containing n-octyl(phenyl) N,N-diisobutyl carbamoyl methyl phosphine oxide, respectively. Ruthenium-106 and 60Co are removed in a column loaded with dimethyl glyoxime and have DFs greater than 20. The amount of secondary wastes arising from absorber materials is calculated to be 300 kg for a 350 t/yr reprocessing plant with an ILWC volume of ∼0.5 m3/t of heavy metal.
