The Liquid Sandwich Vacuum Vessel (LSVV) is a novel alternative to conventional thick steel vacuum vessels. In the LSVV design, liquid lead circulates through channels within thin walls made of silicon carbide ceramic composite (SiC/SiC). By dissipating disruption forces within the liquid lead, the SiC/SiC walls can remain thin, improving heat transfer and the overall efficiency of the fusion reactor.

A literature review explores existing strategies for manufacturing, machining, and joining SiC/SiC components within the nuclear fusion context. A manufacturing plan is proposed for the fabrication and joining of tubular components and walled structures with integrated channels, aiming to further SiC/SiC manufacturing capabilities for the LSVV design.
