A scoping nucleonics study for fusion high-temperature blanket designs
A scoping study was performed to explore tritium breeding and energy-temperature splits in various blanket concepts for high-temperature process heat. Temperature limits for the lithium materials necessitate two blanket zones. One delivers heat at moderate temperatures (< about600/sup 0/C) and breeds tritium. The other is a nonbreeding zone that produces heat at high temperatures. It is found that a system where all blanket modules breed tritium delivers more high-temperature heat than one where only some of the blanket modules produce tritium. Of those considered, a design where the high-temperature zone is placed between two breeding zones produces the highest fraction of high-temperature heat. When liquid lithium, Li/sub 7/Pb/sub 2/ and Li/sub 2/O tritium breeding materials are employed with two breeding zones, a tritium breeding ratio of 1.1 can be achieved while delivering 30 to 40% of the blanket heat at high temperature.
