Disruptions, Runaway Electrons, and Electromagnetic Loads in a Compact Spherical-Tokamak Breeder: A Reduced-Order Assessment on a NIMROD-Verified Equilibrium

A reduced-order assessment of disruptions, runaway electrons, and electromagnetic loads for the compact spherical-tokamak breeder, on a NIMROD-verified equilibrium. Current-quench time 7-19 ms; a SEVERE runaway-electron avalanche (E/E_c about 1128, a beam of order 70 percent of p...

The Tritium Fuel Cycle and Breeding Ladder of a Compact Spherical-Tokamak Breeder

The tritium fuel cycle and breeding ladder of a compact spherical-tokamak breeder, developed as an honest mass balance. The per-unit burn rate follows from the fusion power; the net surplus is a confirmed ladder to the advanced-blanket ceiling. A single advanced unit exports trit...

Fast-Ion and Alpha-Particle Confinement in a Compact Spherical-Tokamak Breeder

Fast-alpha and fusion-product confinement in the deuterium-helium-3 tandem-mirror burner. The mirror-trapped charged products and their loss-cone dynamics set the ash accumulation and the axial power that the direct-energy-conversion and alpha-channeling systems must handle. Repo...

Licensing a Compact Fusion Platform Under the Byproduct-Material Framework

Licensing a compact fusion platform under the United States byproduct-material framework (10 CFR Part 30), confirmed for fusion by the 2023 NRC determination and the ADVANCE Act. The materials-oriented, Agreement-State-administrable, graded path suits a machine whose only signifi...

The DCLC Stabilization Knee: Warm-Plasma Streaming and the Marginal Loss-Cone Microstability of a Deuterium-Helium-3 Tandem-Mirror Plug

The drift-cyclotron loss-cone (DCLC) microstability of a deuterium-helium-3 tandem-mirror plug. A flute-mode electrostatic dispersion solver, cross-checked electromagnetically, maps the exact marginal-stability boundary. The design's warm-ion fill sits exactly on the stabilizatio...

Red-Teaming the Honest Negatives: Bounded Closing Paths for a Compact Spherical-Tokamak Breeder and a Deuterium-Helium-3 Tandem-Mirror Burner

A reduced-order red-team of the binding gates of a compact spherical-tokamak breeder and a deuterium-helium-3 tandem-mirror burner. For each honest negative, alternatives are brainstormed, bounded, ranked, and only the promising ones promoted to high-fidelity validation. The curr...

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...

Negative-Triangularity Turbulence Suppression in a Compact Spherical-Tokamak Breeder: Nonlinear Gyrokinetics of the Quiet Operating Point

Nonlinear gyrokinetics of the compact spherical-tokamak breeder at the frozen negative-triangularity design point. Nonlinear CGYRO with kinetic electrons shows negative triangularity cutting ion-scale (ITG+TEM) transport by 40-45 percent versus a positive-triangularity twin, with...

Isotope Co-Production and 14\,MeV Materials Qualification at a Spherical-Tokamak Breeder

Isotope co-production and 14 MeV materials qualification at the spherical-tokamak breeder. The same fusion-spectrum source provides a high-flux materials-qualification volume many times the reference dedicated facility, and breeds shortage-prone medical isotopes such as molybdenu...

Negative-Triangularity Turbulence Suppression in a Compact Spherical-Tokamak Breeder: Nonlinear Gyrokinetics of the Quiet Operating Point

Nonlinear gyrokinetics of the compact spherical-tokamak breeder at the frozen negative-triangularity design point. Nonlinear CGYRO with kinetic electrons shows negative triangularity cutting ion-scale (ITG+TEM) transport by 40-45 percent versus a positive-triangularity twin, with...
