A Magnetized Target Fusion Plant Using a Rotating Liquid-Metal Liner for Compression and Blanket in One Component

This paper presents a complete, computed design study of a fusion power plant based on a magnetized target fusion device: a spherical vessel in which a rotating liquid-metal liner is driven inward by pistons onto a magnetised plasma target. The fuel is deuterium tritium, releasing 17.6 MeV per reaction, of which 14.1 MeV leaves with the neutron and 3.5 MeV stays with the alpha particle. Heating is by piston-driven compression of a rotating liquid lithium-lead liner onto a magnetised plasma target, and the blanket concept is the liquid liner itself, which is simultaneously compressor, blanket, tritium breeder and heat-removal medium. Sizing follows from a zero-dimensional energy balance evaluated in the accompanying computation: target gain 12.86, time-averaged fusion power 180 MW, driver electrical demand 25.45 MW, gross electric output 93.45 MW and net electric output 53.16 MW. The minimum gain for electrical break-even at the stated driver efficiency is 3.7. Each shot releases 180 MJ of fusion energy from 14 MJ of driver energy delivered to the target, repeated at 1 Hz. The plant verdict on the stated assumptions is net positive. Where a quantity depends on an assumption that experiments have not yet demonstrated at the required value, that dependence is stated numerically so that the design can be re-scored as measurements improve. This study is simulated and computed from stated assumptions; it is not a measurement, and no part of the plant has been built. SIMULATED, NOT MEASURED.
