The Water-Cooled Lead-Lithium (WCLL) Breeding Blanket (BB) concept is one of the candidates to be selected as the driver blanket for the EU-DEMO reactor. The architecture delivered at the end of the pre-conceptual design phase was significantly reviewed to overcome some issues and limitations spotted during an external review.
The present work highlights on the modifications made to the WCLL BB design, such as the adoption of helical-shaped Double-Walled Tubes (DWT), their impact on performances and the suitability of this design to be scaled for testing in both the ITER Test Blanket Module (TBM) and IFMIF-DONES.
To this purpose, due to the new ITER timescale, it would be really interesting to test some WCLL BB mock-ups in the IFMIF-DONES area located behind the High Flux Test Module. This would allow to test and validate different technical solutions in a relevant environment. Indeed, even though the irradiation environment will not envisage the presence of the magnetic field, it should be possible to achieve nuclear and thermal conditions similar to those expected in a fusion reactor.
