摘要： The invention refers to a process and an installation for obtaining the deuterium depleted water which is preferably for food use. The process consists in that water, after purification feeds the continuous isotopic distillation in the presence of a packing on minimum 100 theoretical plates with an efficiency of 8 theoretical plates per meter, the reflux being introduced on the last plate of an upper stripping zone, the number of theoretical plates from the stripping zone and that of the ones from a lower enrichment zone being in a ratio of 10 : 1 and preferably of 9 : 1 , in this latter case resulting 10.5% of the reflux flow as a waste which flows through the enrichment zone with a concentration of under 200 ppm D/(D+H), obtaining 4.5% of the reflux flow deuterium depleted water with a concentration of 20-30 ppm D/(D+H) which is mineralized. The installation in which the process is applied contains a packing consisting of a lower enrichment zone and an upper stripping zone, at the intersection of these zones a and b being connected a thermally insulated isotopic distillation column, between the steam boiler and the column being fitted a level regulating loop (A) placed under the zone in which are injected in the column the vapors provided by the steam boiler, between the vacuum ramp and the top zone (d) and respectively a secondary condenser being connected a vacuum regulation loop (B), the collecting pipe being connected to an intermediate storage tank at which another pipe is connected, fitted with a dosing device, communicating with a mixing pipe provided with static mixing promoters, to which a short pipe is connected provided with another automatic dosing device, connected to a storage tank for a mineralizing additive and a final evacuation pipe connected to a UV sterilizing subsystem.

摘要： A method of oxygen isotope concentration, comprising performing the process of 18 O depletion and/or process of 17 O concentration utilizing an ozone photodissociation reaction by laser beams in combination with the oxygen distillation process for oxygen isotope concentration. In this method, it is preferred to add an isotope scrambling process. When both of the process of 18 O depletion and process of 17 O concentration are carried out, either may precede the other, and these processes can be performed freely before or after the oxygen distillation process. Preferably, at least one of the oxygen distillation process, 17 O concentration process, 18 O depletion process and isotope scrambling process is carried out twice or more. By virtue of this method, stable isotopes of oxygen 17 O and 18 O whose existence ratio is extremely low can be concentrated efficiently to a high level on an industrial scale.

摘要： The present invention relates to a method for treating tritium water-containing raw water, the method including supplying a part of raw water containing tritium water and alkali water to a circulation tank, mixing the raw water with alkali water in the circulation tank to obtain an electrolyte adjusted so as to have a desired alkali concentration, and continuously electrolyzing the electrolyte while circulating the electrolyte, thereby subjecting the raw water stored in the storage tank to alkali water electrolysis and thus gasifying the raw water.
According to the invention, by gasifying tritium water-containing raw water by alkali water electrolysis, the tritium concentration in a tritium-containing hydrogen gas is diluted to 1/1,244 and the tritium water-containing raw water can be reduced in volume.摘要翻译： 本发明涉及一种处理含氚水原水的方法，所述方法包括：将一部分含有氚水和碱水的原水供应至循环罐，在循环罐中将原水与碱水混合以获得 将电解液调节至具有所需的碱浓度，并在使电解液循环的同时连续电解电解液，从而使储存在储罐中的原水受到碱性水电解，从而使原水气化。 根据本发明，通过碱水电解气化含氚水的原水，将含氚氢气中的氚浓度稀释到1/1244，并且可以减小含氚水的原水的体积。
