The 2026 paper series.

The Kronos publication set is two companion papers — one per machine — not a four-part series. Each closes its physics; only the breeder freezes economic structure.

Paper 1

HYPERION — the D–T breeder

Paper 2

The D–³He tandem-mirror burner

Data

Two open deposits (CC BY 4.0)

Earlier plans described a four-part series tied to the single-tokamak design. The frozen 2026 set is two companion papers, matched to the two-machine strategy.

Paper 1 — breeder

HYPERION's physics is closed (Q 3.076, 85.0 MW, 9.66 MA); its economics are frozen as structure, not absolute margins.

Paper 2 — burner

The tandem-mirror physics is closed at the Mode M closing point, stated with its plug-density requirement; economics stay provisional.

Everything traces to two open deposits, and the key results run in the live simulation. See the two 2026 papers for the fuller summary.
