Establish the conceptual engineering baseline and power-balance closure for the AETERNA stellarator fusion reactor following the transition away from tokamak current-drive systems.
Integrated a 300-planar-REBCO-coil magnet topology as the primary magnetic confinement architecture.
Removed the 15 MA central solenoid and non-inductive current-drive systems to reflect pure stellarator physics.
Quantified subsystem power consumption across PbLi circulation, cryogenics, auxiliary plasma heating, and balance-of-plant systems.
Achieved exact numerical closure with 384.1 MWe gross output minus 100.1 MWe internal recirculating power, yielding 284.0 MWe net electrical output.
Constrained internal subsystem loads to 38.0 MWe for auxiliary plasma heating, 26.0 MWe for cryogenics, 21.6 MWe for balance of plant, and 14.5 MWe for PbLi systems.
