SMR Construction Site Heavy Crane Ingress & Reactor Well Rigging Audit

Rigorous engineering audit checklist for verticalizing factory-built SMR modules, crane runway soil stabilization, tandem tailing crane synchronization, and subterranean reactor pool insertion.

Interactive Rigging Readiness Checklist

Complete all 5 phases prior to crane lift hook engagement.

READINESS SCORE 0% (0 / 15 Verified)

Phase 1: Heavy Crane Ingress & Soil Bearing Verification

Plate Load Bearing Test (ASTM D1194) Soil compaction achieves ≥ 98% Standard Proctor with ultimate bearing capacity exceeding 6,000 psf (safety factor ≥ 2.0).

Steel Crane Mat & Hardwood Timber Layout Dual-layer 14-inch heavy Azobé timber mats topped with 1.5-inch structural steel spreader plates beneath crawler tracks.

Subsurface Void & Utility Ground Radar (GPR) GPR geophysical survey completes 100% sweep of crane swing radius to identify underground drainage pipes or buried conduits.

Phase 2: 1,600-Ton Lift Rigging Hardware & NDT Inspection

Trunnion Lifting Lug MPI & Ultrasonic Testing Magnetic Particle Inspection (MPI) and phased array UT confirm zero sub-surface crack indications on vessel lifting trunnions.

Spreader Beam & Grommet Sling Certification Proof-test certified to 1.5x working load limit (WLL) with current calibration tags within 30-day inspection window.

Calibrated Wireless Shackle Load Cells Dual-channel telemetry shackles transmit continuous load measurements to crane cab and lift director HUD displays.

Phase 3: Tandem Tailing & Vessel Verticalization Protocol

Tailing Crane / SPMT Frame Synchronization Secondary 600T tailing crane or hydraulic SPMT tailing frame synchronized via digital radio interlock with main 1,600T crane.

Bending Moment & Saddle Release Verification Continuous monitoring of shell bending moments during 0° to 90° rotation; transport saddle bolts released at 15° tilt angle.

Internal Component Pendulum Oscillation Dampening Internal steam generator tube bundle natural frequencies monitored via triaxial accelerometers to prevent resonant vibration.

Phase 4: Atmospheric Conditions & Crane Hook Wind Limits

Boom-Tip Anemometer < 9.0 m/s (17.5 knots) Continuous sonic anemometer recording at boom tip; 3-second gust limit set strictly to 11.0 m/s with automatic hoist halt.

Lightning Detection & Zero Convective Risk Zero lightning strikes detected within a 25-mile radius during the 6-hour critical lift and insertion window.

Daylight Visibility & Floodlight Backup Array Lift conducted under ambient daylight or backed by dual 200kW generator-fed LED stadium towers illuminate the containment hatch.

Phase 5: Reactor Well Insertion & Baseline Metrology Sign-Off

Dual Total Station Laser Tracker Alignment Leica / FARO laser trackers verify vertical plumblines within 0.5 mm per 10 meters of descent.

Seismic Guide Pin Engagement (≤ 1.5mm Tolerance) Hardened stainless steel guide pins mate with cavity keyways with zero mechanical binding or galling.

Final Load Transfer & Cold Spring Relaxation Crane hook slowly de-tensioned in 10% increments while verifying support pedestal strain gauges and foundation baseline levels.
