What Zachry Nuclear Engineering, Inc. does
Zachry Nuclear Engineering, Inc., founded in 1974 and headquartered in Stonington, Connecticut, is a privately held professional services firm that provides engineering, design, and project management services to the U.S. commercial nuclear power industry. The company operates as a subsidiary of the Zachry Group and maintains a second office in Charlotte, North Carolina. Its service portfolio spans mechanical, electrical, controls, and civil/structural engineering and design, covering the full nuclear plant project lifecycle from conceptual design and feasibility studies through detailed design, construction, and start-up testing. Customer-facing offerings include plant upgrades and modifications, evaluation of code and regulatory compliance, and engineering services for new reactor designs including small modular reactors (SMRs).
The company's technical foundation rests on a Nuclear Quality Program compliant with 10CFR50 Appendix B and ASME NQA-1 (1994), successfully audited by NUPIC, providing it with qualified nuclear QA supplier status. This regulatory posture, together with five decades of singular focus on the nuclear sector and self-performance capabilities delivered under a total-cost-of-ownership model, constitutes the technical and operating core of the business.
Zachry Nuclear generates revenue through project-based professional services engagements delivered directly to nuclear utilities and new nuclear facility developers via an enterprise field sales motion. Pricing is not publicly disclosed but is structured around project scope and compliance-driven deliverables. The firm's customer base is segmented into two primary use cases: existing fleet support for U.S. nuclear utilities and engineering support for entities developing next-generation nuclear facilities, including SMRs.
