Magneto-convective effect on tritium transport at breeder unit level for the WCLL breeding blanket of DEMO [PDF]

Fusion Engineering and Design, 2020
Abstract The Water-Cooled Lithium-Lead (WCLL) is one of the four breeding blanket concepts proposed by Europe in view of its DEMO reactor. The velocity field of the electrically conducting lead-lithium eutectic alloy inside the blanket is strongly influenced by the external magnetic field used for plasma confinement combined with buoyancy effect.

Dynamic thermal-hydraulic modelling of the EU DEMO WCLL breeding blanket cooling loops [PDF]

Fusion Engineering and Design, 2017
A global thermal-hydraulic model of the EU DEMO tokamak, based on an object-oriented approach using the Modelica language, is currently under development at Politecnico di Torino. The first module of the global model will simulate the dynamics of the blanket cooling system and it will be able to investigate different coolant options and different ...

Helical-shaped double wall tubes solution for the breeding zone cooling in the WCLL breeding blanket

Fusion Engineering and Design
One of the two most promising Breeding Blanket (BB) concepts to be chosen as driver design of the EU-DEMO fusion reactor is the Water-Cooled Lead Lithium (WCLL) BB. A crucial point of this key component is the cooling of the BB structural elements and of the Lithium-Lead alloy, used as neutronic multiplier and Tritium breeder.

The DEMO Water-Cooled Lead–Lithium Breeding Blanket: Design Status at the End of the Pre-Conceptual Design Phase [PDF]

Applied Sciences, 2021
The Water-Cooled Lead–Lithium Breeding Blanket (WCLL BB) is one of the two blanket concept candidates to become the driver blanket of the EU-DEMO reactor. The design was enacted with a holistic approach. The influence that neutronics, thermal-hydraulics (

Development of anti-permeation and corrosion barrier coatings for the WCLL breeding blanket of the European DEMO

Fusion Engineering and Design, 2021
Abstract Tritium permeation from breeder material to the Water Coolant System (WCS) in Water Cooled Lithium Lead (WCLL) Breeding Blanket (BB) is one of the technological issues to be solved in the design of the European DEMO. Since the tritium extraction from the Water Coolant System is more challenging and expensive than the extraction from the ...

CFD simulation of the magnetohydrodynamic flow inside the WCLL breeding blanket module [PDF]

Fusion Engineering and Design, 2017
Abstract The interaction between the molten metal and the plasma-containing magnetic field in the breeding blanket causes the onset of a magnetohydrodynamic (MHD) flow. To properly design the blanket, it is important to quantify how and how much the flow features are modified compared with an ordinary hydrodynamic flow.
