ScanCAD PCB Reverse Engineering and Obsolescence Support for Nuclear Power
Keep Critical Reactors Online—When Redesign Isn't an Option
The Perfect Storm: Aging Plants, Surging Demand
America’s nuclear fleet is experiencing a renaissance it wasn’t designed for.
Reactors built in the 1970s and 1980s—originally licensed for 40 years—are now being extended to 60, even 80 years of operation. Plants once slated for retirement are being restarted. The reason? Unprecedented power demand driven by AI data centers, electrification, and the urgent need for carbon-free baseload generation.
But here’s the challenge: the electronics inside these plants weren’t built for an 80-year mission. Instrumentation and control systems, safety logic, power conversion equipment—the silicon hearts of reactor operations—reached obsolescence decades ago. Original equipment manufacturers have long since discontinued these components. The secondary market is drying up.
The plants must run. The parts don’t exist. And redesign? That’s where the real problem begins.
When Redesign Isn’t an Option
Nuclear power operates under the most stringent regulatory framework in American industry—and for good reason. Safety-related equipment must meet exhaustive qualification requirements:
• 10 CFR 50.49 mandates environmental qualification for equipment in harsh conditions
• 10 CFR 50.59 governs any changes to safety-related systems
• IEEE 323 establishes qualification standards for Class 1E electrical equipment
The practical reality: qualifying a redesigned safety-related component can cost $1 million or more and take years to complete. Environmental testing, seismic qualification, aging analysis, documentation—the regulatory pathway for a new design is extraordinarily expensive and time-consuming.
For operators facing immediate obsolescence, redesign simply isn’t a viable option.
Form-Fit-Function: The Only Practical Path
When you can’t redesign, you replicate.
Form-fit-function replacement—creating an exact-match reproduction of the original component—is the practical path forward. When the replacement matches the original in every measurable way, operators can demonstrate equivalence without triggering full requalification cycles.
This is exactly what ScanCAD delivers: the capability to reverse engineer obsolete electronics with the precision required to produce verified exact-match replacements.
One board becomes your source of truth. From a single artifact—even a decades-old, discontinued component—we generate the complete technical data package needed to manufacture replacements indefinitely.
Critical Systems We Support
Instrumentation & Control
The nervous system of reactor operations. Neutron flux monitors, temperature sensors, pressure transmitters, and the signal conditioning electronics that feed safety systems—all vulnerable to obsolescence, all critical to continued operation.
Safety System Logic & Protection
Reactor protection systems, engineered safety features actuation, trip logic—the systems designed to respond in milliseconds when parameters exceed limits. These cannot fail. They cannot be unavailable. And they cannot be casually redesigned.
Power Conversion & Distribution
Inverters, rectifiers, battery chargers, power supplies—the equipment that ensures safety systems have reliable power under all conditions. Much of this equipment predates modern power electronics, with components unavailable for decades.
From Artifact to Qualified Replacement
Our process delivers complete technical data packages from existing hardware:
1. High-Resolution Imaging
Non-destructive capture of PCB geometry at high precision—every trace, via, pad, and plane documented without damaging the artifact.
2. Intelligent Reconstruction
Netlist extraction and schematic generation, creating complete circuit documentation from physical evidence.
3. Complete Technical Data Package
Gerber files, bill of materials, netlist, schematic—everything needed for qualified manufacturing. Documentation sufficient for regulatory review.
4. Validation & Verification
Cross-referenced against the original artifact to ensure exact-match fidelity before manufacturing begins.
5. Manufacturing-Ready Output
Qualified contract manufacturers can produce replacements from ScanCAD data with confidence that form, fit, and function match the original.
Supporting America’s Nuclear Renaissance
Nuclear power provides nearly 20% of U.S. electricity and half of the nation’s carbon-free generation. As AI-driven demand strains the grid, keeping existing nuclear capacity online isn’t just good business—it’s essential to energy security and climate goals.
ScanCAD currently supports critical domestic nuclear power production capacity. We understand what’s at stake: billions in infrastructure investment, regional grid stability, and the skilled workforce that operates these plants.
When an obsolete board threatens reactor availability, the cost isn’t just the component—it’s the megawatts that don’t reach the grid, the carbon-free generation lost, the strain on an already-stressed power system.
