Abstract:

In order to investigate the tritium behaviors in Hastelloy N alloy in molten salt reactor, first-principles calculations are used to study the interaction between
hydrogen and 4d transition metal alloying atom in nickelbased alloy. The interaction energies between 4d elements and H are calculated. Atomic size effects and electron distribution effects are analyzed. The hydrogen–4d interactions are compared with the hydrogen–3d interactions calculated in our previous work.

Key words: Hydrogen, Tritium, Transition metal, Nickel, First-principles calculation
