As a part of the DOE-sponsored Heavy Ion Fusion Systems Assessment (HIFSA) project, a systems and costing computer model has been developed to examine the behavior of a linear induction accelerator-driven (LINAC) HIF power plant. The main purpose of this code is to examine different system and subsystem options as well as a large range of parameter space in which an HIF power plant might operate. The ultimate goals include the identification of: (1) desirable operating regimes, (2) preferred system and subsystem options, (3) systems with major cost impacts, and (4) systems where appropriate research and development or technological breakthroughs could yield significant economic benefits.
