Tritium aging effects in palladium on kieselguhr

[摘要] Fifty wt% Pd on kieselguhr (Pd/k) is used in hydrogen isotope separation processes at the Savannah River Site. Long-term aging studies on this material were undertaken in June 1992. P-c-T data showing the aging effect of tritium loading for long periods will be presented and discussed covering from June 1992 to March 1998. Lowering of plateau pressures and increasing indications of inhomogeneities have been observed in both tritium and deuterium absorption isotherms at 0 degrees C, and desorption isotherms at 80 and 120 degrees C.
