Dispersion and removal of tritium released into the main cell TSTA (Tritium Systems Test Assembly)

Approximately 145 millicuries (about 0.06 cm{sup 3}) of tritium in DT form were released into the main cell of the Tritium Systems Test Assembly at Los Alamos National Laboratory. At equilibrium with the cell isolated, this amount resulted in concentrations of about 50 microcuries per cubic meter throughout the 2900 m{sup 3} of the cell volume. Tritium was held in the cell for 29 minutes before normal ventilation was restored and the tritium was released through the facility's 30-m stack. The dispersion, confinement, removal, and decontamination times associated with this release are discussed in this paper. 5 refs., 2 figs., 3 tabs
