Design analysis demonstrates an integrated breeder and burner fusion platform, indicating a de-risked path to power closure via three specific experiments.
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.
