Recently developed techniques for nondestructive measurement of tritium, separation of hydrogen isotopes, and decontamination of tritium-contaminated materials at the Hydrogen Isotope Research Center (HRC) in Toyama University were introduced. As a nondestructive measuring technique for high level tritium, β-ray-induced X-ray spectrometry (BIXS) was applied to the evaluation of elemental, oxidized, and ad/absorbed tritium, and it was concluded that this technique is fairly available for determination of tritium in gaseous, liquid, and solid states. A new separation technique by gas chromatography using the Pd-based alloy was proposed, which can be operated near room temperature. Performance of the present separation technique was examined by using a mixture of H, D, and T species. Finally, an example of the thermal behavior of tritium absorbed in stainless steel type 316 was shown.
