Abuse and failure paths
Abuse: Fuel cutoff, vendor lock-in, safeguards opacity, safety capture, weapon-adjacent ambiguity.
Failure: Loss of cooling, common-mode design defect, fuel-service interruption, accident.
Required exit and alternatives
Exit: Diverse lawful suppliers, independent regulation, material accountancy, emergency plans, decommissioning funds.
Portability: Design-data escrow and component standardization where lawful; no proliferation-sensitive transfer.
Interoperability: International safety, quality, safeguards, and material-accountancy compatibility.
Independent alternative: Non-nuclear generation, alternate reactor/fuel services, safe shutdown capacity.
Emergency handback: Safe shutdown, cooling, public warning, competent authority control, environmental protection.
Disconfirming evidence
- Failed exit drill
- Unavailable independent alternative
- Retaliation for attempted exit
- Material portability gap
- Undisclosed common-mode dependency
Truth boundary
Static risk-governance record. It does not prove an operational service, market share, capacity, dependency, alternative, or successful exit drill.
Authority and record status
Responsible authority: Independent nuclear safety and safeguards authorities.
Static concentration-governance record; no operational alternative or exit drill is proven.
Revision date: . Public corrections may be initiated through the diplomatic contact route.
