  • Patent number: 11929183
    Abstract: Thorium-based fuel bundles according to one or more embodiments of the present invention are used in existing PHWR reactors (e.g., Indian 220 MWe PHWR, Indian 540 MWe PHWR, Indian 700 MWe PHWR, CANDU 300/600/900) in place of conventional uranium-based fuel bundles, with little or no modifications to the reactor. The fuel composition of such bundles is 60+ wt % thorium, with the balance of fuel provided by low-enriched uranium (LEU), which has been enriched to 13-19.95% 235U. According to various embodiments, the use of such thorium-based fuel bundles provides (1) 100% of the nominal power over the entire life cycle of the core, (2) high burnup, and (3) non-proliferative spent fuel bundles having a total isotopic uranium concentration of less than 12 wt %. Reprocessing of spent fuel bundles is also avoided.

  • Publication number: 20200398307
    Abstract: Articles and methods related to superhydrophobic surfaces are generally described. In some embodiments, an article may include a substrate and a plurality of nanoscale and/or microscale features may be formed on a surface of the substrate by irradiating the substrate. The plurality of nanoscale and/or microscale features may comprise oxides and/or hydroxides on the surface of the substrate. A fluorinated coating may be associated with at least a portion of the surface of the substrate, including, for example, the nanoscale and/or microscale features may be coated with the fluorinated coating.
