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.

Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

Model calculations have been performed to provide guidance for the development of solution spray techniques for coating NIF scale mandrels with 150 μm thick polyimide ablator layers. The deposition models considered assume independent random placement of the spray droplets on the mandrel surface followed by their spreading to form thin disk-like additions. The dependence on the final surface roughness of the effective thickness of the addition, the size (diameter) of the addition, and the cross-sectional profile of the addition have been explored. In addition, a model that assumes randomly placed, independent additions that cover 50% of the mandrel surface per addition is considered For each model and parameter set the rms surface finish is calculated as well as the surface power spectra. The primary result is that individual, randomly placed coating additions must be very thin, on the order of a few nm at most, if NIF surface specifications are to be met.
