| Abstract: | The use of La-Ni-Al metal hydrides to process and store tritium presents unique problems to the handling of tritium. All hydrogen isotopes are ''trapped'' in La-Ni-Al alloys as a function of homogeneity and the degree of activation, or number of full cycles the material experiences before being exposed to tritium. To a lesser extent, the mole fraction of aluminum has an effect on the number of cycles needed for full activation. Data is presented which shows the effect of La-rich second phases on the retentium of protium, the x-ray diffraction line broadening as a function of number of cycles, and the observed ''heel'' in the alpha region of the isotherm due to Ni-Al second phases. There also appears to be an increase in solubility of tritium due to the lattice expansion on the metal. |
