SCP-4388

Expected annual

$3.2M

One-time setup

$22.5M

Annual recurring

$3.2M

Personnel

Initial capital outlay is dominated by specialized underground cryogenic construction, full‑spectrum shielding and site electrical upgrades (~$22.5M). Annual operating costs (~$3.165M/yr) are led by staff wages, energy to run cryogenics/vacuum and recurring reserves/maintenance.

🏗️ One-Time Capital Costs Total: $22.5M

Facilities $15.2M

[#1, #2, #11] Excavation and construction of cryogenic vault, full‑spectrum structural shielding and onsite electrical/substation upgrades; includes civil works, concrete/liner, precision shielding interfaces and site distribution upgrades.

Equipment $4.7M

[#3, #4, #5, #6, #7, #8, #9, #12, #15, #16] Hardware and installed systems: seismic isolation platform, cryogenic refrigeration plant (installation component), vacuum/gas handling, passive dump/load banks, shielded feedthroughs, remote switchgear, generators/UPS (hardware portion), external passive monitoring hardware, emergency response equipment (hardware portion), and electrical suppression installation.

Contingency Reserve Fund $2.0M

[#22] One‑time contingency/reserve fund set aside for emergency repairs, offsite damage, temporary relocation and major rapid response costs.

Initial Research And Lab Setup $300K

[#18] Setup of safe test rigs and remote apparatus for permitted testing, external stimulus shrouds and initial procedural/safety approvals.

Initial Retrieval And Transfer $300K

[#20] Design/build Faraday‑shielded vibration‑isolated transport crate and initial secured transfer/convoy/heavy lift for retrieval to Site-11.

🔄 Annual Recurring Costs Total: $3.2M/yr

Staff Wages $1.3M/yr

[#13, #14] Salaries, benefits and fully loaded costs for containment engineers/technicians and 24/7 security guard detail (specialists + guards).

Research And Monitoring $425K/yr

[#12, #18, #21, #25] Remote environmental monitoring operations, ongoing test program operations/safety reviews, continuous EM/environmental exclusion enforcement, and incident investigation/forensic documentation.

Policy Reserve $300K/yr

[#27] Annual policy/reserve allocation for opportunity cost mitigation, external remedial liabilities and planning contingencies.

Supplies And Consumables $295K/yr

[#4, #6, #17, #26] Cryogenic consumables/electricity component allocated to operations, passive load bank water/disposal & upkeep, routine spares/PPE/consumables, and small repair contingency for object casing.

Facilities Maintenance $245K/yr

[#5, #8, #9, #16, #23] Maintenance and certifications for vacuum and atmospheric control systems, switchgear testing, backup generators/UPS testing/fuel handling, suppression inspection/recharge and averaged long‑term shielding/structural refurbishments.

Cover Story And Legal $200K/yr

[#19] Ongoing legal, cover‑story, information control and liaison with local authorities and regulatory compliance budgets.

Training And Readiness $200K/yr

[#15, #24] Recurring training, drills, vetting, clearances and administrative overhead for emergency teams and personnel.

Energy Consumption $200K/yr

[#10] Continuous electricity and generator fuel for cryogenic refrigerators, vacuum pumps, isolation systems and environmental controls.

Logistics And Transport $0/yr

[#20] Initial retrieval covered as one‑time; recurring per‑move transport costs are episodic and budgeted via contingency/reserve rather than baseline annual spend.

⚡ Cost Scenarios

📊 Baseline (baseline) $3.2M/yr

92.8% probability / year

Normal year with routine maintenance, monitoring and no major containment incidents.

routine_operations scheduled_maintenance

🚨 Minor Incident $3.6M/yr

6.0% probability / year +$400K vs baseline

Localized electrical discharge or equipment failure requiring emergency response, limited repairs and downtime.

arc_flash_event local_equipment_failure

🚨 Major Breach $4.7M/yr

1.0% probability / year +$1.5M vs baseline

Significant containment failure causing equipment destruction, larger repairs, public mitigation and reserve drawdown.

large_energy_release major_equipment_damage

🚨 Catastrophic Breach $13.2M/yr

0.2% probability / year +$10.0M vs baseline

Rare catastrophic energy release with large‑scale damage, mass amnestics, extensive reconstruction and reserve replenishment.

uncontrolled_closed_circuit seismic_triggered_release

👥 Personnel 19 total

Role	Count	Notes
Containment Engineer / Technician	7	[#13] Electrical engineers, cryogenics technicians, EM specialists and seismic engineers providing 24/7 technical oversight and maintenance.
Security Officer / MTF Agent	12	[#14] Armed site guards and supervisors covering multiple shifts, training and escort duties.

📋 Confidence Notes

Estimates are built from analyst ranges in containment notes and the article; core capital items and recurring categories are well described but many anomalous risks (scale of energy releases, incident frequency) remain uncertain, so figures are medium confidence.
