The ancillary systems of the European test blanket modules: Configuration and integration in TIER

The conceptual design of the ancillary systems of the European Test Blanket Modules (TBMs), namely the PbLi circuit, the Helium Cooling Systems (HCSs), the Coolant Purification Systems and Tritium Extraction Systems (TESs), is proceeding as per time schedule adopted by the European Domestic Agency for ITER (Fusion for Energy (F4E)). A general description of these systems, based on the present baseline, is given in this paper.
