⚡ Cost Scenarios

📊 Baseline (baseline) $2.9M/yr

93.5% probability / year

Normal year with single active site, ongoing research and standard maintenance; no major incidents.

no incidents routine research normal maintenance

🚨 Minor Incident $3.2M/yr

4.0% probability / year +$250K vs baseline

Localized accident or minor breach requiring repair, increased PR/legal costs, and short-term medical care.

minor breach or vandalism localized tunnel collapse small-scale legal inquiry

🚨 Major Breach $4.1M/yr

0.5% probability / year +$1.2M vs baseline

Serious containment breach, large-scale medical emergency or legal exposure requiring regional ERT mobilization, site reconstruction, and litigation costs.

major cave-in or breach public exposure/legal action serious medical complications

🚨 Research Breakthrough Requiring Scale Up $3.5M/yr

2.0% probability / year +$600K vs baseline

Positive but expensive outcome: research requires scale-up of cohort studies, expanded imaging and staffing.

promising experimental results need to recruit/monitor many additional subjects expanded clinical testing
