ABSTRACT

            The main purpose of the Tritium Recovery System (TRS) is to reduce to a maximum possible extent the release of tritium from the facility following a tritium release in confinement boundaries and also to have provisions to recover both elemental and vapors tritium from the purging gases during maintenance and components replacement from various systems processing tritium. TRS configuration is a combination of permeators, a platinum microreactor (MR) and a trickle bed reactor (TBR) and consists of two branches: one branch for elemental tritium recovery from tritiated deuterium gas and the second one for tritium recovery from streams containing low amount, below 5%, of tritiated gas but significant water vapors. The two branches shall work in a complementary manner in such a way that the bleed stream from the permeators shall be further processed in the MR and TBR in view of achieving the required  decontamination level.

          This work/paper shows the configuration of Tritium recovery system and the operating mode for tritium retention.

          Keywords: tritium retention, permeators, platinum microreactor, trickle bed reactor.
