What Analysis and Measurement Services Corporation does

Analysis and Measurement Services Corporation (AMS) is a privately held nuclear engineering consulting firm founded in 1977 and headquartered in Knoxville, Tennessee, specializing in testing the instrumentation and control (I&C) systems of nuclear power plants, research reactors, and next-generation reactor developers. The company's core offering centers on verifying the performance and response times of safety-related I&C systems, ensuring that nuclear facilities can execute timely shutdown when process variables exceed safety limits. AMS's technology stack includes proprietary testing platforms such as the Time Events Analyzer (TEA) data acquisition system, Control Element Drive Mechanism (CEDM) diagnostic equipment, the AMS Online Calibration Monitoring system, and cable aging/condition monitoring methods based on Loop Current Step Response (LCSR) and Frequency Domain Reflectometry. The firm also operates an A2LA-accredited EMC qualification laboratory (Cert. No. 3483.01) and provides electrical signature analysis for motor/generator diagnostics. Its patent portfolio of 24 granted and 2 pending U.S. patents is supported by 400+ technical publications and 35 DOE SBIR research grants over 40 years.

The business operates a hybrid revenue model combining professional services (I&C performance testing, engineering consulting, training via ams-courses.com, and EMC qualification) with hardware sales of custom data acquisition platforms. The go-to-market is sales-led and direct to enterprise: AMS delivers on-site field services, custom equipment provision, and consulting engagements to nuclear utilities, reactor OEMs (Westinghouse for AP1000 commissioning), national laboratories (Oak Ridge), and regulatory bodies (NRC topical report work). Customer reach spans 26 countries and essentially all U.S. nuclear power plants. The firm's competitive position is anchored by 10CFR50 Appendix B QA accreditation, A2LA lab certification, regulatory engagement with NRC/IAEA/EPRI/IEC/ISA, and the deep domain expertise of a management team with over 300 years of combined nuclear industry experience. The company has begun extending its capabilities into SMR, microreactor, and Gen-IV reactor qualification, positioning for a nuclear new-build cycle that includes Vogtle Units 3 & 4 and a growing pipeline of advanced reactor deployments.

Broad incumbents

• Mirion Technologies: Public radiation detection and nuclear instrumentation company serving nuclear power, defense, medical, and industrial markets. Overlaps with AMS in nuclear measurement and monitoring but operates at much greater scale across a broader nuclear portfolio.
• Curtiss-Wright Corporation: Public diversified industrial manufacturer supplying nuclear I&C, reactor protection systems, and qualification testing services to naval and commercial nuclear markets. Comparable in nuclear I&C scope but operates across defense, aerospace, and energy.
• Westinghouse Electric Company: Global reactor OEM and nuclear services provider operating the AP1000 fleet with which AMS partners. Comparable customer base and overlapping I&C engineering scope, though Westinghouse is far larger and verticalized across reactor design, fuel, and services.
• Framatome: France-based global nuclear reactor OEM and services company providing I&C, instrumentation, and plant services across European and international fleets. Comparable in plant-level I&C scope but operates across fuel, components, and full reactor services.
• AECOM: Global engineering services firm with a substantial nuclear practice covering decommissioning, environmental remediation, and plant engineering services. Comparable in serving nuclear utility customers but operates at far greater scale across infrastructure, water, and environment.

Others

• Jensen Hughes: Global fire protection, security, and risk-based engineering consulting firm with a significant nuclear safety consulting practice. Adjacent to AMS in nuclear regulatory and safety consulting but focused on PRA, fire protection, and risk rather than I&C testing.
• Bechtel Corporation: Global EPC contractor with deep nuclear power plant design and construction heritage, including U.S. Navy naval reactors and commercial new-build programs. Adjacent to AMS as a nuclear ecosystem participant but focused on EPC rather than I&C testing services.
