Estimated one-time capital and contingency construction costs are large (~$6.79B) driven by extremely deep hardened subterranean construction, heavy shielding and large contingency reserves; recurring operations are substantial (~$134.5M/year) driven by maintenance, power/cooling, consumable shielding replacement and specialized staffing/MTF readiness.

📋 Confidence Notes
High uncertainty in frequency and scale of Nova Events, shielding consumption rates, rebuild costs and political/legal exposures; many estimates are wide ranges and scenario-driven, so overall confidence is low.
