Nuclear manufacturing demands the highest standards of precision, traceability, and material integrity. EDM Zap has been engineering EDM solutions for nuclear applications since 1971 — including custom E-Series power supplies built specifically for energy sector requirements.
Our Products
High-performance generators engineered for stability, speed, and minimal electrode wear.
Learn More →Specialized configurations for simultaneous machining and maximum throughput.
Learn More →Purpose-built systems designed from the ground up for your specific manufacturing challenge.
Learn More →Precision tooling, filtration, and consumables to keep your machines running perfectly.
Learn More →We don't just build the machine we engineer your entire process.
Learn More →Nuclear components operate in environments where failure isn’t an option. Reactor internals, fuel rod assemblies, control mechanisms, and pressure boundary components require dimensional accuracy and material integrity that goes beyond standard manufacturing tolerances — with full documentation and traceability at every stage.
EDM is uniquely suited to nuclear applications. No cutting force means no residual stress in critical zirconium, stainless, and specialty alloy components. No heat-affected zone means material properties are preserved. And the process can hold tolerances that conventional machining simply cannot achieve in these materials.
EDM Zap developed its E-Series power supply specifically for nuclear and energy sector customers — built to tighter tolerances, with enhanced documentation and traceability requirements. Our technicians have traveled internationally to support nuclear EDM operations, and we understand what this industry demands.
Nuclear Applications
Precision machining of zirconium alloy fuel rod components, spacer grids, and assembly hardware — held to nuclear-grade tolerances with full material traceability and process documentation.
Complex geometry machining of stainless and specialty alloy reactor internal components — no cutting force, no heat distortion, and full dimensional verification at every stage.
Precision EDM machining of control rod drive mechanisms and associated components — where dimensional accuracy and surface integrity are directly tied to operational safety.
Machining of pressure vessel penetrations, nozzles, and fittings in heavy-wall stainless and alloy materials — to ASME and nuclear quality assurance standards.
