COMPARISON BETWEEN WATER DISTILLATION PROCESS AND HYDROGEN ISOTOPE EXCHANGE PROCESS FOR DEPLETION AND ENRICHMENT OF TRITIUM IN LIGHT WATER. Autori: MASAMI SHIMIZU, KENJI TAKESHITA. |

Rezumat: The dimensions of typical tritium separation processes, water distillation process and the hydrogen-isotope exchange process with hydrophobic Pt-catalyst, were evaluated numerically for the recovery of tritium from wastewater generated by the decommissioning of Magnox reactor. Both the column diameter and the column height required for the hydrogen-isotope exchange process were much smaller than these for the water distillation process. The application of hydrogen-isotope exchange process to the treatment of the tritiated wastewater is effective for not only the reduction of process dimensions but also the depression of energy consumption. | |||||||
