Definitions
- This invention relates to a method and practical device composition for purification of air from tritium in gaseous form (T 2 ) and concentrating tritium in form of super-heavy water (tritium oxide, T 2 0) or tritiated water(HTO) in common water.
- the method and composition find application in purification of air from tritium in repositories in which tritium is in form of a gas molecule (T 2 ) as well as processes, equipment and facilities for extracting of Tritium (T 2 ) from spent nuclear fuel and processes, equipment and facilities for production and storing of Tritium (T 2 ) for the needs of thermonuclear reactions. Radioactivity is always detected in the air around equipment and in facilities where Tritium is stored due to the extreme mobility of Tritium in gaseous form.
- Triutium is oxidized in a hermetically sealed chamber at high temperature in the flame of oxyhydrogen coming from an oxyhydrogen generator. After the processing, the obtained mixture of air and water vapours from tritiated and super-heavy water is pumped out of the oxidation chamber, cooled through a cooler and the condensed water is trapped in a water filter. Tritium purified air is then returned to the space/equipment for storing Tritium. The tritiated water trapped in the water filter is fed in portions to the oxyhydrogen generator where it is converted to oxyhydrogen. The obtained gas is used to oxidize the Tritium from the next portion of air containing Tritium. That cycle can be repeated unlimited number of times during which the concentration of Tritium in the water of water filter increases proportionally to the number of cycles.
- Tritiated water is broken down in the oxyhydrogen generator to oxyhydrogen mixture containing oxygen molecules 0 2 and molecules of the three Hydrgoen isotopes (H 2j HT, T 2 ).
- the next volume of gas containing Tritium is processed in the flame of the obtained oxyhydrogen mixture from above. That way the concentration of Tritium in the volume of common water increases constantly and at the n-th cycle it is n times higher than in the first one.
- a tritium target containing 0,01 grams of Tritium with activity of 3,57.10 12 break downs per second ( 3,57.10 10 Bq) is held in a metal container.
- the air is treated with a flow of burning oxyhydrogen from a generator(8) with delivery rate of 100 1/h at temperature of 1000-1300°C.
- the obtained water vapours are cooled and separated in a water filter(12) with 500 grams of water.
- the air purified from water vapours is returned to the container. After that way of purification of 200 M 3 of air the water from the water filter is deionized and is transferred to the oxyhydrogen generator.
- the generator In the generator it is transformed to gaseous oxyhydrogen mixture with oxygen and hydrogen in stoichiometric proportion.
- the oxyhydrogen mixture Through a pump and a dosing system the oxyhydrogen mixture is fed to a chamber for treating of the incoming for purification gas.
- the cycle of breaking down of tritiated water to oxyhydrogen, extraction of Tritium from gaseous mixtures, separation of the tritiated water from the gas and obtaining oxyhydrigen again from it is repeated 200 times.
- the concentration of Tritium in the water of the water filter is increased by a coefficient of 200 compared to the first cycle if the initial concentration of Tritium in the air is kept constant and reaches 4.10 6 Wq/kg H 2 0 (1,43.10 "8 grams T/l kg H 2 0).
