Abstract:

Tritium radioluminography and tritium autoradiography have been applied to V3.5(Zr, Ti, Ni) protium absorption alloy with a two-phase structure of BCC phase and Laves phase to examine the behavior of protium. By these methods, tritium distribution has been graphically displayed, and both the tritium and protium concentration on the surface of the alloy have been evaluated. The protium concentration in the BCC phase and Laves phase in this alloy has been determined to be 1.4 mol% and 2.3 mol% respectively. It has been found that the preferential path for the protium penetration into the alloy is not the BCC phase but the Laves phase.
