METHOD AND PRACTICAL DEVICE COMPOSITION FOR PURIFICATION OF AIR FROM GASEOUS TRITIUM AND CONCENTRATION OF TRITIUM IN A CONSTANT VOLUME OF WATER

摘要

Spent nuclear fuel production is accompanied by obtaining amount of radioactive Tritium which is highly mobile and is difficult to confine. That leads to possible radioactive contamination around equipment and storing facilities (4). The Tritium in the air recovered from these spaces is oxidized in an oxyhydrogen flame (1) and the resulting mixture of air and water vapours containing also tritiated and super-heavy water is condensed (17) and passed through a water filter (14). The water from the water filter (14) is then fed to the oxyhydrogen generator (8) where it is converted to oxyhydrogen and the obtained gas is used to oxidize the next portion of air containing Tritium. Repeating that cycle increases the concentration of the Tritium in the water of the water filter (14) proportionally to the number of cycles.
