SCP-5827 Euclid ~ medium confidence
SCP-5827
Expected annual
$2.8M
One-time setup
$8.8M
Annual recurring
$2.7M
Personnel
19
Initial setup ~ $8.75M (one-time) driven by bespoke high-density shielded cell, remote-handling systems, HPC/instrumentation and contingency/decommissioning reserves; recurring annual costs ~ $2.70M driven primarily by staff wages, security, radiation safety, waste disposal and ongoing monitoring.
🏗️ One-Time Capital Costs Total: $8.8M
Decommissioning Fund $5.0M
[#24] Lifecycle decommissioning/disposal fund set aside to cover eventual long-term disposal/reconstruction of activated structures; mid-range funding given large uncertainty.
Contingency Reserve $1.0M
[#23] One-time contingency reserve for rapid procurement of shielding, emergency contracting, or large unexpected disposal events.
Facilities $650K
[#1] Construction of a sealed humanoid cell with 20 cm high-density concrete (33% lead pellets) including reinforced floor/ceiling, shielded hatch/door and labyrinth seals; estimate covers materials, specialized mixing, structural labor and shielded door.
Equipment $650K
[#3, #4, #12, #13, #16, #21] One-time purchase/installation of neutron-moderation/absorption panels (borated polyethylene/B4C), radiologically rated HVAC & filtered exhaust system, remote handling (manipulators/gloveboxes), quarantine shelving/drums, effluent treatment equipment (if installed), and an initial shielded cask for transport.
Structural Replacement Reserve $500K
[#15] One-time reserve to fund potential partial replacement/entombment of activated cell components (site/site-specific; lower-end planning reserve).
Potential Large Waste Disposal $500K
[#14] Budgeted one-time liability for an off-nominal medium/high-level waste disposal event (activation of structures) - conservative planning allocation.
Initial Research And Lab Setup $350K
[#5, #17] Initial instrument suite (area monitors, neutron spectrometers, survey meters) and one-time HPC / storage for astrophysical/stellar-creation research and data analysis.
Shielding Materials Initial $100K
[#2] Initial purchase of lead pellets to achieve 33% volume fraction in concrete and associated regulated handling/transport costs.
🔄 Annual Recurring Costs Total: $2.7M/yr
Staff Wages $1.6M/yr
[#7, #8, #9, #10] Salaries and benefits for Radiation Safety Officer + technicians, lead researcher + astrophysicist + technicians + part-time psychiatry, security guards and supervisor, and medical on-call staffing; reflects the largest recurring cost driver.
Cover Story And Legal $200K/yr
[#20] Legal counsel, regulatory compliance, permits, cover-story/public affairs budget and counter-leak measures.
Contingency Fund Annual Allocation $200K/yr
[#23, #24] Annual allocation toward contingency/decommissioning reserve to smooth funding for rare large disposal or replacement events.
Research And Monitoring $170K/yr
[#5, #12, #15, #17] Ongoing calibration/maintenance of neutron/gamma monitoring suite, remote-handling maintenance, activation monitoring surveys and telescope/collaboration time for astrophysical follow-up.
Miscellaneous Overhead $150K/yr
[#25] Pro-rated site utilities, administrative support, permitting, and record-keeping allocations.
Logistics And Transport $140K/yr
[#21, #14, #13] Licensed transport contracts, routine radioactive waste handling/disposal budgeting (small annual volumes), and quarantine storage/operations costs.
Supplies And Consumables $98K/yr
[#6, #11, #18, #19] Personnel dosimetry & bioassays, PPE and contamination-control supplies, specialized measurement consumables/calibration sources replacement, and routine library/quarantine handling costs.
Facilities Maintenance $40K/yr
[#4, #15, #16] HVAC energy, filter replacement, backup fan maintenance and routine cell maintenance/inspections and maintenance of decontamination infrastructure.
Training And Drills $40K/yr
[#22] Regular staff training, annual radiation incident drills and behavioral-trigger drills; SOP updates.
Shielding Materials Replacement $30K/yr
[#2] Periodic replacement/handling costs for lead pellets if contaminated/compacted.
Neutron Moderation Replacement $10K/yr
[#3] Occasional replacement/repair of borated polyethylene/B4C panels if activated or degraded.
⚡ Cost Scenarios
📊 Baseline (baseline) $2.7M/yr
81.5% probability / year
Normal uneventful year with no major activations or large disposals; routine operations, monitoring and staffing.
no activation of surrounding structure normal waste volumes standard staffing and monitoring
🚨 Minor Incident $2.9M/yr
15.0% probability / year +$220K vs baseline
Small activation or contamination event requiring emergency response, extra disposal and short-term overtime.
localized activation of books or equipment small-volume waste requiring licensed disposal short-term increased decontamination/transport
🚨 Major Activation $4.9M/yr
3.0% probability / year +$2.2M vs baseline
Significant activation of cell-adjacent materials requiring partial structural replacement/entombment and large licensed disposal.
activation of structural elements large-volume medium-level waste extensive contractor work for removal/entombment
🚨 Catastrophic Activation $12.7M/yr
0.5% probability / year +$10.0M vs baseline
Severe activation requiring site-level decommissioning, large-scale disposal and multi-million dollar remediation in a single year.
widespread activation of containment full-cell replacement and off-site disposal major contractor mobilization

📋 Confidence Notes
Notes provide detailed line-item ranges for construction, staffing and recurring consumables which supports a medium confidence in near-term estimates; however neutron-induced activation and radioactive waste disposal remain highly uncertain and can produce multi-million-dollar outliers, lowering overall confidence.
