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.

Direct waste transfer process quickens at Savannah River Site
The Department of Energy Office of Environmental Management’s liquid waste contractor at the Savannah River Site this month marked the first direct transfer of decontaminated waste from the Salt Waste Processing Facility (SWPF) to the Saltstone Production Facility (SPF). This is a new step in optimizing waste processing, according to the DOE.

Experiments on deuterium permeation through S.S.316L with FeAl/Al2O3 composite coating have been performed in the temperature range 277-600°C at driving pressures 1-50kPa. As comparison, the tests for samples with natural oxidation film and Ni-plating have also been performed. The apparent deuterium permeability in the sample with FeAl/Al2O3 coating is an order of magnitude lower than that with natural oxide layer, and is at least three orders of magnitude lower than that in the non-oxidized material by inference. The apparent activation energy of deuterium permeation is 76.6kJ/mol for the coated sample and 61.3kJ/mol for the sample with natural oxidation film. The exponential dependences of steady flux for the samples on the pressure are 0.89 for FeAl/Al2O3 coating, 0.65 for natural oxidation film, and 0.55 for Ni-plating, that reflects different permeation mechanism for various surfaces. In addition, the trapping effect of defects on hydrogen isotope was inferred according to the different characteristic of permeation flux curves for various samples.
