An aqueous self-cooled shielding blanket for NET

A low-technology Aqueous Self-Cooled Blanket (ASCB) concept has been proposed for a shielding/driver blanket for the Next European Torus (NET). NET will operate with a low temperature minimal shielding-thickness blanket in the first operation stage to provide room for a larger plasma chamber, thereby relaxing some of the plasma physics constraints. An ASCB blanket utilizes small amounts of lithium compound dissolved in the water to breed tritium, and is especially applicable to gain tritium breeding experience based on available technology. Such a shielding blanket could provide a significant part of the tritium needs for NET, even with the minimal shielding blanket dimensions
