  "what_if": "Radiant would need to enter NRC licensing to sell power commercially — a DOE demonstration on a national laboratory site is not a commercial licence. It would also need a HALEU TRISO supply that does not yet exist at volume. The engineering claim is credible; the schedule depends almost entirely on fuel.\n",
  "notes": "Designed from the outset to fit a standard shipping container, sized to replace diesel generators at remote sites, disaster areas and military bases. At 1.2 MWe it is roughly a thousandth of a large reactor — the point is not scale but transportability and the fact that diesel is the incumbent it has to beat, not grid power.\n",
