Preliminary investigation of Li4SiO4 pebbles structural performance

Fusion Engineering and Design, 2021
Abstract One of the main purposes of a breeder blanket is to remove the heat produced in the blanket by the fusion reaction neutrons, and to breed the tritium required to sustain it. To achieve these requirements, several breeder materials (solid or liquid lithium-bearing ones) have been investigated in the past decades.
