DEVICE FOR TRAPPING TRITIUM AND SYSTEM FOR MEASURING A CONCENTRATION OF TRITIUM IN THE AIR

摘要

The invention concerns a device (100) for trapping tritium contained in the form of tritiated water vapour in an air flow (F), comprising - a member (200) for collecting an air flow, and - a condenser (300), designed to condense the water vapour contained in the air flow, the condenser comprising a closed reservoir (310), an air inlet (320) linked to the air collecting member, a means (330) for cooling the collected air, and an air outlet channel (340), the trapping device being characterised in that it further comprises means (310) for recovering the quantity of condensed water, and in that the air inlet of the condenser (320) comprises a straight channel (321) that extends inside the reservoir (310), and the means (330) for cooling the air inlet comprises at least one condensation pipe (331) arranged around the channel (321), and into which a heat transfer liquid is injected at a negative temperature.
