The effects of hydrogen on the helium behavior in palladium

As one candidate of tritium storage materials,palladium subjects to the damage from helium atomsintroduced by the β-decay of tritium atoms. The mechanical properties of palladium will be greatly degradedderiving from the accumulation of helium atoms. A set ofinteratomic potentials has been fitted ba...

Summary:As one candidate of tritium storage materials,palladium subjects to the damage from helium atomsintroduced by the β-decay of tritium atoms. The mechanical properties of palladium will be greatly degradedderiving from the accumulation of helium atoms. A set ofinteratomic potentials has been fitted based on ab initiocalculation according to the Morse formula. Moleculardynamic methods are utilized to investigate the existenceof H atoms on the release of helium atoms from palladiumwith the present fitted potentials. It is found that hydrogenatoms play significant roles in the diffusion and release ofhelium atoms. The presence of hydrogen atoms tends toobstacle the diffusion and release of helium atoms inpalladium.
