[#19] Contingency/reserve fund to be held available for large emergency responses, lockdowns, mass medical response, and remediation (kept as an on-hand reserve).

[#1, #2, #8, #9] Structural build/retrofit costs: dedicated vacuum-compatible inner cell ($750,000), adjacent byproduct quarantine cell ($300,000), localized shielding & structural radiation protection ($200,000), and initial power/UPS/generator circuit work ($100,000).

[#3, #4, #5, #6, #7, #27] Initial hardware and installed devices: high-vacuum system ($150,000), vacuum-compatible robotic manipulators ($300,000), radiation/particle monitoring suite ($250,000), high-resolution diagnostic instruments ($400,000), DAQ hardware ($120,000), and small research benchtop instruments ($50,000). (Initial portions only; recurring maintenance/capex captured separately.)

[#25] One-time cost estimate for decommissioning/final disposal planning and execution (range $200k–$1,000k; mid-range assumption used).

[#20] One-time estimate for a significant decontamination/major cleanup event (range given in notes $50k–$200k; budgeted at upper range for planning).

[#18] One-time cost per domestic transfer for armored/shielded crate, specialist rigging, and escort (~$50,000/domestic; international transfers are higher and handled as project events).

[#10, #11] Ongoing personnel compensation: 6full-time guards (base ~$50k each -> $300k base, ~$390k with benefits/overhead) plus containment/research team salaries (Senior Researcher $180k + 2×$120k + 2×$70k = $560k base; with benefits/overhead ≈ $730k). Aggregated recurring staff wages ≈ $1,120,000/yr.

[#21, #26] Legal retainers, misinformation/liaison operations (~$200,000/yr) plus ongoing negotiation/insurance/indemnity planning/legal work (~$500,000/yr assumption for government-level arrangements).

[#16, #28, #24] Baseline experimental/test program funding (~$250,000/yr), simulation & theoretical research funding (~$225,000/yr midpoint), and long-term data archival (~$15,000/yr midpoint).

[#30] Annual contingency set-aside (~10–20% suggested). Mid-range planning value used (~$400,000/yr).

[#12] On-call hazardous-response readiness, specialized radiology coverage, training and ambulance readiness (~$200,000/yr).

[#17] Allocation for occasional external accelerator/beamline collaborations (range $100k–$1,000k per campaign; baseline assumes occasional modest campaigns averaged to $100k/yr).

[#29] Pro-rated Site-17 utilities, administrative overhead, janitorial, and general facility allocation (~$100,000/yr).

[#15, #9] Routine maintenance contracts and facility-level upkeep: service contracts for pumps/detectors/manipulators/HVAC (~$60,000/yr) plus fuel & generator maintenance (~$20,000/yr).

[#7] Ongoing DAQ, storage, and compute costs (midpoint of $40k–$100k/yr assumed; large off-site runs are treated as project scenarios).

[#13] Dosimeters, periodic medical surveillance and cohort health monitoring (~$15,000/yr for badges + ~$50,000/yr for surveillance).

[#18] Recurring logistics allocation for occasional site-to-site transfers/transport averaging one domestic transfer per year (~$50,000/yr average). Individual transfers cost more when international; those are treated as project events.

[#6] Consumables, calibration, and maintenance for mass spectrometers, trackers, and high-speed diagnostics (~$50,000/yr).

[#20] Budgeted routine hazardous waste handling and disposal (~$50,000/yr).

[#23] Annual containment and response drills, equipment training (~$50,000/yr).

[#5] Calibration, replacement, and servicing for detectors and spectrometers (~$30,000/yr).

[#22] Internal/external ethics reviews and audits (~$30,000/yr).

[#14, #27] Annual consumables and cleanroom supplies: O-rings, seals, gloves, filters (~$20,000/yr) plus small-equipment consumables (~$7,500/yr midpoint).

[#4] Maintenance and spare parts for vacuum-compatible robotic manipulators (~$25,000/yr).

[#3] Spare parts & scheduled maintenance for roughing/turbo pumps, seals, bearings (~$15,000/yr).
