Expected annual

$3.1M

One-time setup

$13.0M

Annual recurring

$3.1M

Personnel

Estimated one-time capital and contingency costs are approximately $13.0M, driven primarily by vault/shielding construction, insurance reserve and a large contingency reserve; recurring annual costs are roughly $3.05M/yr, driven by staff wages, legal/cover operations, waste handling, and ongoing monitoring/maintenance.

⚡ Cost Scenarios

📊 Baseline (baseline) $3.1M/yr

89.9% probability / year

Normal year with no major containment incidents; routine operations, limited testing and standard maintenance.

no incidents limited/suspended testing routine maintenance

🚨 Minor Incident $3.2M/yr

8.0% probability / year +$150K vs baseline

Moderate contamination or small-scale transmutation event requiring targeted decontamination, limited medical treatment and waste disposal.

localized plating activation limited contamination small-scale decontamination

🚨 Major Breach $5.1M/yr

2.0% probability / year +$2.0M vs baseline

Significant conversion of containment materials, multi-person contamination requiring extended remediation, legal exposure and facility repairs.

explosive vaporisation of activated plating multiple casualties large-scale contamination

🚨 Catastrophic Breach $18.1M/yr

0.1% probability / year +$15.0M vs baseline

Full facility remediation required with long-term environmental cleanup, mass casualties, major legal settlements and total rebuild.

📋 Confidence Notes

Estimates are based on analyst ranges and the documented incident history; many line items have wide ranges (per-incident vs routine) and depend on testing cadence and site choices, so confidence is moderate.
