Tritium Extraction and Heavy Water Upgrading Plant Brochure

The concentrator is part of a system to remove tritium from water. It starts with purification to make sure the water is suitable for the next stage in the process. An electrolyzer converts the water to hydrogen and oxygen gas; and the hydrogen, containing the tritium, is collected separately and is passed through the concentrator. Here tritium rising with the hydrogen isotopes in the concentrator columns is transferred to descending water, resulting in higher concentrations in the bottoms water. Tritium-free hydrogen is released. Increase in tritium concentration of 1000 times or more can be achieved.
