It important that air emissions from tritium systems be kept as low as reasonably achievable. Thus, over the years a number of gas detritiation systems have been developed. An often-used system for this purpose is one which oxidizes tritium in all forms to tritiated water followed by collection of the tritiated water on an adsorbent. These systems have been shown to be very effective at reducing tritium emissions. However, recently there has been interest in lower-cost, simpler systems which do not convert HT to the much more hazardous HTO form. One example of such a system is one based on a bubbler and dehumidifier. The bubbler collects HTO by exchange with its H 2 O, and it humidifies the gas. The dehumidifier condenses water (HTO and H 2 O) from the gas and returns it to the bubbler. Besides the bubbler/dehumidifier, this paper will also consider a dehumidifier/collector and an adsorber/collector (defined later). A computer model of each configuration was written and run. The results are used to compare each system's performance. Tritium buildup in each system's liquid water, and tritium exhausted to the environment are presented and compared for all three systems.
