  • Publication number: 20220223303
    Abstract: Proposed are nuclear fuel pellets showing high oxidation resistance in a steam atmosphere and a method for manufacturing same. The method includes: preparing a powder mixture by mixing a sintering additive powder including Cr2O3, MnO, and SiO2 with a uranium dioxide powder; forming a molded body by subjecting the powder mixture to compression molding; and sintering the molded body in a weak oxidative atmosphere in which an oxygen potential is ?581.9 kJ/mol to ?218.2 kJ/mol. The nuclear fuel pellets contain 0.05% to 0.16% by weight of the sintering additive composed of Cr2O3, MnO, and SiO2. A liquid phase generated during the sintering accelerates grain growth and inhibits reaction between uranium dioxide with steam by forming a film at the grain boundary of the uranium dioxide. This reduces leakage of a fission material by improving high-temperature water vapor oxidation resistance at around 1204° C. in a loss-of-coolant accident condition.

  • Patent number: 10504771
    Abstract: A method for manufacturing a semiconductor device includes: forming a sacrificial layer on a first substrate, the sacrificial layer being made of a material whose lattice constant is different from that of germanium (Ge) by a preset threshold or below; forming a germanium (Ge) layer on the sacrificial layer; forming an insulation layer on a second substrate; bonding the germanium (Ge) layer onto the insulation layer; and removing the sacrificial layer and the first substrate by etching the sacrificial layer in a state where the germanium (Ge) layer is bonded to the insulation layer. In this method, a germanium-on-insulator (GeOI) structure having various surface orientations may be formed by means of epitaxial lift-off (ELO), and a strain may be applied to the germanium (Ge) layer using a lattice constant of the sacrificial layer.
