摘要：

We have compared deuterium ingress into thin (1.5-4.5-mu-m) foils of Zr, Zircaloy-2 and Zr-2.5wt.% Nb using the D(He-3, p) He-4 nuclear reaction. The foils were mounted in a compact cell in a vacuum chamber and the foil and liquid in the cell were analyzed with a He-3 beam. We introduced deuterium into the foils by etching their native oxide layers with a solution of 0.1% NH4HF2 in D2O. The amount of deuterium taken up by the foils was measured in situ as well as in separate experiments ex situ in which the etched surfaces were turned toward the beam. The results show that deuterium uptake occurs in the order Zr-2.5wt.% Nb < Zr < Zircaloy-2.
