Design Blueprint: A Reversed-Field Pinch Fusion Reactor: Self-Organised Confinement, Ohmic Heating to Ignition Conditions and Wall Loading

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24159765): This paper presents a complete, computed design study of a fusion power plant based on a reversed-field pinch: a toroidal pinch in which the plasma current generates a toroidal field that reverses sign near the wall. 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 ohmic heating by the plasma current itself, sustained by the dynamo effect, with a small radio-frequency assist, and the blanket concept is helium-cooled lithium ceramic breeder blanket behind a graphite-armoured wall. Sizing follows from a zero-dimensional energy balance evaluated in the accompanying computation: fusion power 553.9 MW, auxiliary heating 30 MW, plasma gain Q 18.46, neutron power 443.8 MW, first-wall neutron loading 2.039 MW per square metre, gross electric output 276.8 MW, recirculating power 68.61 MW and net electric output 208.2 MW. Radiated bremsstrahlung removes 10.96 MW and transport removes 279.2 MW, against alpha-particle self-heating of 110.2 MW. 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. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
