We integrate Human Performance fundamentals and tools, Institute of Nuclear Power Operations principles, Lean Enterprise, and Six Sigma with the Westinghouse Quality Management System to support continuous improvement, our nuclear safety culture, and a safety conscious work environment.

The work processes NPO uses also provide opportunities for the improved efficiencies and innovation that our customers expect. We use SAP® enterprise resource planning software to manage production from the moment an order is entered until the final product is delivered to our customer. We manage material traceability, master bill of material/design management, shop floor control processes, and quality assurance through SAP for everything from first-of-a-kind builds to replacement components and systems.

The NPO Electrical Operations manufacturing schedule is level loaded but remains flexible to meet our customers’ requirements. We are prepared to supply our customers with high quality and timely, cost-effective replacement parts and also respond quickly to emergent needs.

The EMA and I&C shop can provide build-to print solutions for I&C, electrical, and electro-mechanical systems serving operating plants across the global nuclear industry. We are a part of the Westinghouse team dedicated to meeting customers’ needs for extended plant life, reduced operating costs and maximized up-time for operating plants.
