Prediction of hydrogen flux through sulfur-tolerant binary alloy membranes.

Metal membranes play a vital role in hydrogen purification. Defect-free membranes can exhibit effectively infinite selectivity but must also provide high fluxes, resistance to poisoning, long operational lifetimes, and low cost. Alloying offers one route to improve on membranes based on pure metals such as palladium. We show how ab initio calculations and coarse-grained modeling can accurately ...

Microstructure and Mechanical Strength of Surface Ods Treated Zircaloy-4 Sheet Using Laser Beam Scanning

Zirconium alloys have been used as a fuel cladding material for a long time because they have good corrosion resistance and irradiation stability in a reactor environment. However, it was recognized that the severe oxidation and creep ballooning behaviors of zirconium alloy cladding tubes at an accident condition of a nuclear reactor have to be considered to improve nuclear plant safety after t...

Thermophysical and Mechanical Analyses of UO2-36.4vol % BeO Fuel Pellets with Zircaloy, SiC, and FeCrAl Claddings

The thermophysical performance and solid mechanics behavior of UO2-36.4vol % BeO fuel pellets cladded with Zircaloy, SiC, and FeCrAl, and Zircaloy cladding materials coated with SiC and FeCrAl, are investigated based on simulation results obtained by the CAMPUS code. In addition, the effect of coating thickness (0.5, 1 and 1.5 mm) on fuel performance and mechanical interaction is discussed. The...
