Nuclear recommissioning requires confidence in measured reality. Systems that have been offline or modified over time often no longer reflect legacy documentation. Engineering decisions must be based on current, traceable dimensional data.
East Coast Metrology delivers long range 3D scanning and precision measurement services that provide extremely accurate dimensional documentation of all assets in their current state. When combined with controlled execution disciplines, this data supports safer and more predictable return to service activities.
Accurate Data and Controlled Execution When It Matters Most
Nuclear recommissioning is not the time for assumptions. Systems that have been offline for extended periods often deviate from drawings, prior baselines, and historical records. Geometry shifts. Interfaces change. Access constraints evolve. The margin for error is minimal.
Successful recommissioning depends on two things. Knowing exactly what exists in the field and executing corrective work with precision. This is where long range 3D scanning and on-site machining work best as a single, coordinated effort.
Capturing True As Built Conditions Before Work Begins
Long range 3D scanning provides a complete and accurate representation of current plant conditions. Unlike legacy drawings or partial measurements, scanning captures geometry, spatial relationships, and clearances across large and complex environments.
In addition, 3D scanning provides extremely accurate dimensional documentation of all assets in their current state. This establishes a reliable digital record that engineering, maintenance, and regulatory teams can reference throughout the recommissioning process.
For recommissioning projects, this data is used to:
- Verify equipment positions and elevations
- Identify accumulated movement or distortion
- Confirm access paths and work envelopes
- Detect interferences before crews mobilize

Translating Scan Data Directly Into Machining Execution
When scanning and machining teams operate independently, valuable context is often lost. When they work together, scan data becomes an execution tool.
Scan data is used to:
- Define machining reference frames
- Validate cut locations and tolerances
- Confirm equipment interfaces before metal is removed
- Reduce field adjustments during critical path work
Machining crews enter the plant with clear intent, validated dimensions, and fewer unknowns. This shortens setup time and reduces risk during live execution.
Reducing Rework and Schedule Risk During Recommissioning
Recommissioning schedules are compressed. Any delay has cascading effects across testing, validation, and regulatory milestones.
A single team approach reduces risk by:
- Eliminating conflicting datasets between vendors
- Aligning measurement methods across disciplines
- Preventing fit up issues discovered after machining begins
- Allowing real time verification during execution
When scan data, machining, and verification are aligned, issues are addressed before they impact startup.
Supporting Verification and Readiness for Return to Service
After machining work is complete, the same scanning and measurement technologies are used to confirm final conditions.
This supports:
- Post work verification against required geometry
- Documentation for engineering and regulatory review
- Confidence that systems are ready for recommissioning activities
Using one coordinated team ensures consistency from initial data capture through final validation.
Why One Team Matters in High Stakes Nuclear Work
Recommissioning is not a collection of isolated tasks. It is a sequence of tightly linked decisions and actions. Fragmented responsibility increases risk.
A unified scanning and machining team provides:
- One source of truth for dimensional data
- Direct communication between data capture and execution
- Faster response to field conditions
- Greater accountability for outcomes
Recommissioning demands accuracy, coordination, and discipline. Long range 3D scanning defines reality. Precision machining acts on it. When both are delivered by one integrated team, nuclear facilities reduce uncertainty, control risk, and move toward safe return to service with confidence.
Dimensional accuracy is not optional during nuclear recommissioning. Verified data reduces risk, improves coordination, and strengthens documentation for engineering and regulatory review.
