The capability of Ni-Ni and Fe-Ni electrodes for electrolytic enrichment of tritium are evaluated. The tritium separation factors for Ni-Ni and Fe-Ni electrodes are in a range of 5-25 and 20-40, respectively. The tritium separation factor with a Fe-Ni electrode is systematically higher than that with a Ni-Ni electrode when the electrolysis is conducted under the same conditions. For Fe-Ni electrode, samples having the same final volume show almost the same tritium concentration factor even if the tritium separation factor of these samples are different by about 20. This is not the case for Ni-Ni electrode because most of tritium separation factors are lower than 20. For the Fe-Ni electrode, the tritium enrichment factor of each sample may be obtained simply from the final volume, without the time consuming procedure for the measurement of the deuterium concentration factor.
