Current design of the European TBM systems and implications on DEMO breeding blanket

This paper gives an overview of the design status of the HCLL and HCPB-TBM (ancillary) systems, updated to the conclusion of the conceptual design phase (CDR). The most relevant technologies, the still open points, the main issues related to the integration in ITER and last relevant results from the on-going R&D activities carried out in Europe are presented and discussed. In the last part, different considerations are proposed about the impact of the design and operation of the main HCLL and HCPB-TBM ancillary systems technologies on the design of a DEMO BB.
