Product Testing for the Nuclear Power, Aerospace, DoD and Commercial Industries

Facility Highlights

NTS Huntsville, formerly Wyle Laboratories, is a 115.6 acre, 238,196sq. ft. facility located in Alabama which provides support and testing services to the Aerospace, Defense, Commercial, Nuclear, and Health Information Systems markets.

In addition to testing, the facility also provides engineering support services for the design of specialized test equipment, including the WAS 3000 and WAS 5000 Acoustic Noise Generators and test facilities. It also contains a "Hot Shop"/Radioactive Material License, world class high-flow steam and water capabilities and on-site engineering and failure analysis.

NTS Huntsville’s reputation as a testing laboratory is unparalleled. It is a recognized leader in independent environmental testing and has supported the aerospace, defense, nuclear energy, telecommunications, transportation and voting systems industries for more than 50 years. NTS Huntsville has qualified more equipment than any other company in the industry. Its technical staff provides a broad expertise base available to support any program. Many technical staff are members of IEEE SC2 Working Groups and ASME OM-1 and QME-1 Committees to support nuclear industry standards.

NTS Nuclear Center of Excellence

Huntsville is home to NTS' Nuclear Center of Excellence, including newly merged services from the Acton, Massachusetts facility. NTS offers nuclear utilities and suppliers worldwide superior customer service in the provision of a full range of engineered services. Testing, equipment qualification, commercial grade dedication, engineering solutions, component supply and field services are provided under our NUPIC and NIAC audited 10CFR50 Appendix B quality program.

As part of our core competency, NTS focuses on the selection of new nuclear grade components, their qualification, and, if needed, their dedication for safety related applications. We currently offer qualified replacements for many electrical and mechanical safety-related components that are no longer available from the OEM.

NTS certifies equipment for Class 1E installation for mild or harsh environments to IEEE 323 and IEEE 344. These systems include instrumentation, digital recorders, batteries, gauges, motors, panels and chillers from manufacturers such as Bussman, Siemens, Yokogawa and GE. NTS can also provide engineering evaluations to determine the best potential replacement from over 200 manufacturers of nuclear grade equipment. With a focus on solving plant needs, NTS leads the industry in digital upgrades, MCC bucket replacements, motor rewinds, governor rebuilds, modifications to or design of replacement safety-related systems, and instrumentation panel and component design. All programs are conducted in accordance with 10CFR50 App. B and 10CFR21.
