| Outline of Final Research Achievements |
In order to propose the possibility of the in-situ separation of tritium oxide from a large amount of the polluted water used with the emergency treatment for preventing from inflicting further damage on the nuclear-power-supply accident, we carried out study on the distillation of water including a small amount of tritium oxide under the irradiation of Nd-YAG laser. Because the frequency of the laser is of 9397 cm-1 that is close to the asymmetric stretching level (0,0,4) of tritium oxide ; 9332 cm-1, we think that the selected excitation induces to the preferential distillation of tritium oxide. Before the distillation the 10 mL-sample indicated the averaged value of 50 ± 30 Bq. The distillate samples at 98.1℃ and 101.8℃ were showed 50 ± 44 Bq and 51 ± 38 Bq, respectively. From the results, we conclude no contribution of the infrared-irradiation on the preferential distillation of tritium oxide.
