Abstract
The TPS is a hydrogen isotope separation system put into operation within the Tokamak Fusion Test Reactor (TFTR) tritium systems. The TPS extracts and purifies tritium from TFTR plasma exhausts, then returns it for reuse as plasma fueling. The TPS operates in two stages: separation of hydrogen isotopes from the TFTR plasma waste effluents via a Pd/Ag diffuser; and separation of hydrogen isotopes via a multi-stage cryogenic distillation system. TPS interfaces with the Gas Holding Tanks (GHTs), the Torus Cleanup System (TCS), the plant stack via the Tritiated Vent System, the Tritium Storage and Delivery System, and the Tritium Storage and Delivery Cleanup System (TSDCS). Commissioning of TPS included: operational testing at CFFTP and at Princeton, thorough helium and tritium leak checks a trial run with a limited tritium inventory (1000 Ci), and a 10000 Ci integrated systems test.
