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.

Workshop highlights commercial fabrication of universal waste canister
Deep Isolation announced that it hosted its third technical workshop for the UPWARDS project, a Department of Energy Advanced Research Projects Agency-Energy (ARPA-E) initiative aimed at developing a universal canister system (UCS) for the disposal of radioactive waste streams from advanced reactors. The workshop, held at R-V Industries in Honey Brook, Pa., focused on the large-scale manufacturing and commercialization of the UCS.

A scanning electron microscope is used to investigate techniques for performing microanalysis of highly radioactive material from the Three Mile Island Unit 2 reactor. Wavelength dispersive X-ray (WDX) spectrometer methods allow quantitative analysis of metallic and oxide phases in samples with radiation fields of up to 60 R/h (contact β-γ). It is found that sputtered gold provides an unexpectedly useful specimen coating for remote analysis, being easily applied and forming more uniform layers than evaporated carbon, and proving compatible with quantitative point analysis. Through a combination of electron imaging, shielded energy dispersive spectrometry, WDX dot mapping, and quantitative WDX point analysis, it is possible to obtain data on core metal oxidation, trace concentration fission product distribution, and phase composition for core temperature estimation.
