h i g h l i g h t s• Experiences from the Tritium Systems Test Assembly were examined.• Failure rates of copper piping and a flame arrestor were calculated.• The calculated failure rates compared well to similar data from the literature.• Tritium component failure rate data support fusion safety assessment. a b s t r a c tThe Tritium Systems Test Assembly (TSTA) was a facility dedicated to tritium handling technology and experiment research at the Los Alamos National Laboratory. The facility was operated with tritium for its research and development program from 1984 to 2001, running a prototype fusion fuel processing loop with ∼100 g of tritium as well as small experiments. There have been several operating experience reports written on this facility's operation and maintenance experience. This paper describes reliability analysis of two additional components from TSTA, small diameter copper gas piping that handled tritium in a nitrogen carrier gas, and the flame arrestor used in this piping system. The component failure rates for these components are discussed in this paper. Comparison data from other applications are also presented.

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.
