  1. 1. The effect of dissolved hydrogen on spent nuclear fuel corrosion

    Författare :Patrik Fors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; alpha-doped; Nuclear waste repository; Hydrogen; Solubility; Corrosion; UO2; MOX; Spent nuclear fuel; High burn-up; Groundwater;

    Sammanfattning : In case of a canister failure in a deep bedrock repository for nuclear fuel, the release of radiotoxic nuclides to the groundwater will depend on the chemical environment near the fuel surface.Due to the presence of large amounts of iron in the canister, hydrogen will be formed if the canister becomes groundwater flooded.

    Sammanfattning : A series of analytic and numerical models have been developed for the prediction and interpretation of the energy spectrum of the neutron emission from thermonuclear deuteriumtritium (DT) plasmas. The main component of the neutron emission, due to reactions between thermal fuel ions, has been modeled as well as minority components due to the presence of fast (supra-thermal) ions. LÄS MER

  4. 3. Development of Differential Die-Away Instrument for Characterization of Swedish Spent Nuclear Fuel
