摘要

The terminal solid solubility of hydrogen for pure Zr, Zircaloy-2, Zr–M (M = Fe, Sn, Cr, Ni) was measured, whose dependency on additive element was elucidated in relation to the integrity of fuel cladding. The present experimental method was in good accordance with the previous reports. The terminal hydrogen solid solubility for Zircaloy-2 was larger than that for pure Zr, the reason for which was considered that the solute Sn leads to decrease the free energy of α Zr phase.
