A Shear-Capped Fusion Reactor: Power Balance for a Deuterium-Tritium Plant Limited by Torsion Shear

This paper presents a complete design study of a deuterium-tritium fusion reactor whose plasma density is capped by a torsion shear ceiling rather than by its magnets, computed throughout from stated assumptions. At a temperature of 20 keV and the capped density, the plant produces 1588.1 MW of fusion power, of which 315.8 MW appears in alpha particles, against 12.3 MW of bremsstrahlung loss. Gross electric output is 630.3 MW and net output after recirculation is 472.7 MW. Fusion power rises from 397.0 MW at 10 keV to 3573.3 MW at 30 keV at the same capped density. Every figure is a computed result of the stated model and nothing was built or tested: the study is SIMULATED, NOT MEASURED, and its limits are stated as plainly as its performance.
