Initial capital expenditures are dominated by a bespoke, radiologically shielded containment hangar and associated civil works (~$112M) plus specialized heavy equipment and contingency reserves, producing total one-time startup costs nearing $197M. Annual operations are driven by staff wages, active monitoring, logistics/rotation and thermal/power needs, totaling roughly $14.5M/yr in a low-intervention baseline.

📋 Confidence Notes
Analyst notes provide detailed line-item ranges for most costs enabling a reasoned mid-range estimate, but large uncertainties remain in final containment construction costs, the feasibility/cost of entombment, and the probability/scale of rare catastrophic events.
