⚡ Cost Scenarios
📊 Baseline (baseline) $2.2M/yr
88.0% probability / year
Normal uneventful year with standard operations, monitoring, testing and no major incidents.
no activation beyond sanctioned tests regular maintenance and testing only
🚨 Minor Incident $2.4M/yr
10.0% probability / year +$150K vs baseline
Small contamination or localized detonation requiring cleanup, limited disposal and short-term testing pause.
small radiological contamination single-unit accidental activation or handling incident
🚨 Major Breach $10.2M/yr
2.0% probability / year +$8.0M vs baseline
Significant radiological release or chain-reaction detonation causing extensive cleanup, infrastructure replacement and legal liabilities.
mass activation or sympathetic detonations major radiological contamination requiring long-term remediation

Role Count Notes
Security Officer / MTF Agent 12 24/7 armed guard coverage with rotation; used 12 FTEs to match staffing cost estimate (~$750k fully burdened).
EOD / Ordnance Specialist 5 On-call and dedicated ordnance techs for render-safe operations; budgeted to match ~$400k/yr.
Research Scientist / Technician 5 Combined PIs and technicians (blended salaries) to match recurring scientific staffing budget (~$500k/yr).
📋 Confidence Notes
Analyst notes provide detailed line-item ranges and recommended midpoints, enabling a reasonable budgetary estimate, but the object's anomalous and potentially catastrophic behaviors (radiological explosions, uncertain failure modes) create substantial tail risk and parameter uncertainty.
