Hyperion is a compact D–T spherical-tokamak breeder — the isotope foundry Kronos builds first, producing the tritium, helium-3, and 14 MeV neutrons a fusion economy needs. Open, on the record. 307 pages.
The spherical-tokamak design — magnets, center stack, blanket, vessel, and heating.
Tritium, helium-3, and 14 MeV neutrons — the strategic products, and materials qualification.
Fusion gain, tritium breeding ratio, negative triangularity, and the honest gates.
Construction from Q2 2027 — the gates, the FOAK→NOAK→BOAK path, and the engineering.
REBCO magnets, the hafnium-carbide first wall, shielding, and cryogenics.
The 81-analysis reproducible record, benchmarks, and what remains to prove.
