“…All of the monitors addressed in these experiences are the most widely used Kanne chamber type, which draws room air into an ionization chamber by means of a small air pump. 7 TSTA recorded a few operational release events. 1,8 Due to some research regarding tritium movement in room air, there have also been several small-mass tritium release tests performed at TSTA 9,10 and at the Tritium Process Laboratory (TPL) caisson facility at Tokai-mura operated by the Japan Atomic Energy Agency.…”

“…One of the best known and most used methods of verifying compliance with tritium effluent water release limits is to take periodic grab samples of effluent water and analyze the water samples in a liquid scintillation counter (LSC) [6]. The LSC is well suited to detect the low energy beta particles emitted by tritium decay.…”

Monitoring tritium facility and fusion experiment effluent streams is an environmental safety requirement. This paper presents data on the operating experience of a solid scintillant monitor for tritium in effluent water. Operating experiences were used to calculate an average monitor failure rate of 4E-05/hour for failure to function. Maintenance experiences were examined to find the active repair time for this type of monitor, which varied from 22 minutes for filter replacement to 11 days of downtime while waiting for spare parts to arrive on site. These data support planning for monitor use; the number of monitors needed, allocating technician time for maintenance, inventories of spare parts, and other issues.
