[en] During FY '83 the Li₂O solid-breeder, helium-cooled canister blanket emerged as the LLNL-UW choice for driving the low-temperature (<750C) portion of the GA process. The 25% fraction of heat to the high temperature process (≤950C) was provided either electrically (joule-boosting) or directly from a high-temperature zone of the blanket. In addition, the LLNL-UW group played a significant part in the MARS synfuel synfuel design in collaboration with TRW, Inc. The MARS synfuel blanket has a combined LiPb inner zone, with a SiVC-LiAO₂, high-temperature outer zone for driving the GA hydrogen synfuel process. Providing 3-dimensional neutronics analysis of power deposition and tritium breeding in both blankets was an important part of the UW-Rowe and Assoc. work. In both the LLNL-UW and MARS studies, the fusion driver as the Axi-Cell, A-cell version of the tandem mirror reactor (TMR). Physics parameters consistent with the synfuel interface were determined as part of the work. Defining and analyzing the thermal-electric interfaces between the TMR and the synfuel process continues to be of prime importance. The analysis of thermal transport and energy conversion in the interface, as well as thermal hydraulics analysis of the blanket, were part of the UW-Rowe Assoc. work
