Remarks on the performance of the EU DCLL breeding blanket adapted to DEMO 2017

Abstract The capability of the breeding blanket to efficiently fulfill its main requirements: tritium breeding, power extraction and neutron shielding is strongly sensitive on the variation of the geometrical constraints imposed by plasma physics and the integration with the rest of the plant systems. Within the Power Plant Physics and Technology Programme, EUROfusion is developing a Dual-Coolant Lithium-Lead (DCLL) breeding blanket based on the multi-module segment approach. In the current DEMO reactor specification released in 2017, the outboard blanket thickness has been decreased with the aim of providing better stability to the plasma and increasing its elongation. Besides, the first wall has been shaped in order to optimize the heat flux loads from the plasma. This work describes the main aspects of the adaptation of the EU DCLL breeding blanket to the characteristics of DEMO 2017 and assesses the influence of the changes on its thermal-hydraulic and neutronic performances.
