The Kronos Integrated Platform: A Spherical-Tokamak Breeder and a Deuterium-Helium-3 Burner as One Strategic-Materials and Power Architecture

The integrated Kronos platform as one architecture: a compact negative-triangularity spherical-tokamak breeder supplying tritium, helium-3, neutrons, and isotopes, and a deuterium-helium-3 burner supplying power at a low neutron fraction, sharing a REBCO magnet basis and a single physics de-risking record. Closure is stated in two tiers throughout: closed-on-model versus closed-demonstrated. The distance to demonstrated closure is three named experiments, not open physics.
