$3.7M

One-time setup

$32.9M

Annual recurring

$3.5M

Personnel

First-year capital (one-time) is dominated by procurement of a Scranton Reality Anchor and contingency reserve (~$32.9M total one-time); annual operations are dominated by staff, continuous power and site-wide lost-productivity costs (~$3.456M/yr baseline).

⚡ Cost Scenarios

📊 Baseline (baseline) $3.5M/yr

90.8% probability / year

Normal operational year with no major incidents; routine maintenance, staffing, power and monitoring costs only.

no SRA failures no emergence-driven containment events routine maintenance only

🚨 Minor Incident $5.0M/yr

8.0% probability / year +$1.6M vs baseline

Localized SRA anomaly or Hume fluctuation requiring emergency response, equipment repairs and partial replacement of spares; short-term productivity losses.

SRA glitch small containment breach emergence event causing limited spread

🚨 Major Breach $13.5M/yr

1.0% probability / year +$10.0M vs baseline

Significant SRA failure or prolonged Hume disturbance requiring full SRA replacement, large remediation and extended downtime for parts of Site-04.

SRA catastrophic failure multiple containment failures extended remediation

🚨 Catastrophic Breach $28.5M/yr

0.2% probability / year +$25.0M vs baseline

Worst-case trans-dimensional contamination or CK-level event triggered by SCP-3621 emergences or SRA failure requiring site expansion/decommissioning and multi-million remediation.

SRA fails during major emergence large-scale trans-dimensional contamination site-wide decommissioning/major remediation

📋 Confidence Notes

Analyst notes provide detailed line items and ranges, but the largest single drivers (SRA capital cost and long-run productivity loss) have very wide ranges and high uncertainty; therefore confidence is medium.
