Tritium oxidation in atmospheric transport
This study has been performed in support of the DOE/AL Tritium Limits Working Group (TLWG). The goal of the TLWG is to provide a technical basis for nuclear facility tritium limits based on test data, accident experience, and sound analytical modeling. Measured Tritiated water/tritium (HTO/HT) have shown that an HTO/HT conversion ratio of 0.01 would bound all the measured data by a factor of 2 to 500 for a downwind distance of up to 15 km. The 99.7% HTO/HT quantile is 6.1 x 10{sup -3}. Use of the HTO/HT ratio of 0.01 with site-specific or conservative meteorological data for three Los Alamos tritium facilities would bound the doses calculated based on the dose factors derived from sophisticated tritium transport codes with conservative meteorological and physical conditions. As a result, the proposed methodology, i.e. use of an HFO/HT conversion ratio of 0.01 with site-specific meteorological data or conservative meteorological data would provide an upper bound for off-site doses, and is recommended.
