SCP-6166

Expected annual

$998K

One-time setup

$1.0M

Annual recurring

$969K

Personnel

One-time capital costs are dominated by heavy lead shielding, structural reinforcement, and specialized instrumentation (HPGe, cameras, robotics). Recurring costs are dominated by security staffing, medical/nursing oversight, waste handling, and a long-term sequestration surcharge, yielding substantial annual operating expenses.

🏗️ One-Time Capital Costs Total: $1.0M

Equipment $325K

[#3, #6, #7, #8, #10, #11] Includes custom lead-lined containment door, remote/IR cameras and fiber inspection hardware, radiation detection systems (area monitors + HPGe), electronic dosimeters, robotic/telemanipulator systems, and hospital-quality containment bed and life-support hardware.

Facilities $260K

[#1, #2] Lead shielding procurement/fabrication/installation and structural reinforcement (floor/footing/permits/engineering).

Initial Research And Lab Setup $125K

[#19] Initial multi-month characterization research program (imaging, spectral analysis, radiochemistry, biological assays) and lab setup.

Contingency Reserve $100K

[#24] Up-front contingency reserve for unforeseen capital/containment upgrades and incident funds.

Shielded Waste Cask $60K

[#17] Shielded waste cask / interim shielded storage procurement for radioactive/biohazard waste.

Ventilation Installation $32K

[#4] Labyrinthine/lead-lined ventilation ductwork installation, tortuous paths, dampers and hazardous-rated fans; one-time install costs.

Legal And Cover Initial $30K

[#20] Initial legal counseling, records redaction, cover-story setup and related documentation costs.

Power Redundancy $30K

[#22] UPS bank and small backup generator procurement and installation.

Hvac Integration $20K

[#5] Integration with site HVAC, redundancy and alarmed environmental control installation.

Decon Kit Initial $15K

[#18] Initial decontamination kits, portable shielding, showers and emergency response equipment.

Personnel Training Initial $12K

[#16] Initial radiation safety, containment and emergency-response training and drills setup.

Data Archival And It $12K

[#21] Secure video/sensor archival, encrypted storage setup, secure communications hardware.

Lead Encapsulation $12K

[#23] Initial encapsulation/paint/coating of lead surfaces to control lead dust and corrosion.

Ppe Initial Stock $6K

[#9] Initial stock of lead aprons, thyroid shields, lead gloves, respirators and disposable protective suits.

🔄 Annual Recurring Costs Total: $969K/yr

Staff Wages $460K/yr

[#13, #14, #15] Security staffing (6 guards with benefits and overtime), nursing/medical oversight (part-time or fractional nurse), and Radiation Safety Officer oversight (fractional FTE).

Long Term Sequestration Surcharge $260K/yr

[#25] Long-tail liability surcharge to reflect indefinite emission obligations (20–25% of capital + perpetual replacement/monitoring costs); represents ongoing sequestration and replacement liabilities not easily amortized.

Research And Monitoring $86K/yr

[#7, #19] Calibration and service for radiation detection (HPGe calibration, cryogen/cooler maintenance) plus ongoing research program costs (spectral analysis, biological studies).

Waste Disposal And Storage $55K/yr

[#17] Annual contracts for radioactive/medical waste handling and disposal or costs of long-term licensed storage if disposal not possible.

Contingency Replenish $50K/yr

[#24] Annual replenishment of contingency/incident funds as used for unexpected events.

Supplies And Consumables $20K/yr

[#9, #11, #12] Ongoing PPE replacement/disposal, IV pump disposables and battery replacement, and medical consumables (IV fluids, tubing, catheters, dressings, syringes, basic meds).

Cover Story And Legal $12K/yr

[#20] Ongoing legal counsel, records management, cover-story maintenance and PR support.

Facilities Maintenance $9K/yr

[#4, #5, #6] Ventilation filter replacement and duct maintenance, HVAC maintenance and integration upkeep, and remote monitoring hardware maintenance.

Personnel Training Recurring $6K/yr

[#16] Annual refresher training and drills (radiation safety, emergency response).

Decon Refresh $3K/yr
