Tritium processing systems for HCPB-TBM

One of the most challenging issues in the TBMs testing campaign to be accomplished in ITER is the correct and efficient recovery of the generated tritium. For the European HCPB-TBM the main auxiliary systems involved in this task and directly interfaced with the TBM itself are the TES (Tritium Extraction System), which purpose is to extract from the ceramic breeder all the generated tritium, sending it to TEP (Tokamak Exhaust Purification) system, and CPS (Coolant Purification System) which extracts the permeated tritium from He-coolant and keeps controlled the chemistry of the primary cooling circuit. Both TES and CPS have to be compatible with: - the performance requirements inherent to the different ITER operational phases; - the ITER space requirements; - the requirements in terms of interface with the ITER tritium processing; - the need to produce results ''DEMO'' or, more in general, ''Reactor'' relevant In this paper, first of all the expected composition of the feed flow-rate to be processed by TES and CPS is given for all the foreseen ITER operational phases. Moreover, the principal process options potentially able to fulfil the above mentioned requirements for both TES and CPS are indicated and discussed. Finally, in the light of the operative conditions planned for the experimental campaign on TBMs, the most suitable process option for TES and CPS are presented together with their preliminary design, taking also into account the possibility to adapt these systems and the related technologies to the EU HCLL-TBM.
