The falsifiable claims.

A credible design says what would prove it wrong. Kronos states its case as falsifiable claims — each a specific prediction with a clear failure condition.

Form

Specific predictions with failure conditions

Breeder claims

Confinement, exhaust, triangularity

Burner claims

Plug density, closure, direct conversion

Purpose

Make the design refutable, not just plausible

Each claim below is meant to be tested and, if it fails, to count against Kronos.

1. Breeder confinement. Nonlinear gyrokinetics will support a confinement multiplier near H₉₈ = 2.28. Fails if turbulence caps confinement below that.
2. Breeder exhaust. The divertor can meet the ≈90% radiated-fraction requirement. Fails if detachment physics cannot reach it at the design's heat flux.
3. Breeder breeding. A tritium breeding ratio up to ~1.8 is achievable. Fails if realistic blanket coverage falls short.
4. Burner closure. D–³He closes (Q_E > 1) at the Mode M point. Fails if the power balance does not reproduce — it does, from the deposit.
5. Burner plug density. An end-plug density ~16× the central cell is reachable. Fails if plug physics caps the ratio far below 16 — the biggest bet.
6. Direct conversion. Charged-particle collectors reach their assumed efficiency. Fails if the electron channel and thermal barrier erode it.
7. Fuel logic. Breeder decay helium-3 can seed a burner demonstrator. Fails if inventory or handling falls short.

Some of these are demonstrated, some reproducible, and some — notably plug density — are open requirements. All are stated so they can be checked.
