Commercial Grade Dedication

Westinghouse technical expertise and test equipment leads the nuclear industry in commercial grade dedication (CGD).

CGD is a process whereby a commercial grade item is designated for use as a basic component that will perform its intended safety function in a nuclear power plant, thus rendering the commercial grade item equivalent to an item previously designed and manufactured under a 10 CFR 50 Appendix B nuclear quality program. Reasonable assurance is provided by identifying critical characteristics of the commercial grade item and qualifying them to nuclear standards by test, inspection or analysis.

An original designer of nuclear plants around the world for over 40 years, from the first commercial nuclear plant at Shippingsport to today’s AP1000 plants, Westinghouse is uniquely qualified to identify the critical characteristics and the methods necessary to verify such critical characteristics. Westinghouse employs extensive in-house testing and inspection capabilities, including chemical, physical and dimensional, as well as specialty test equipment, such as motor dynamometers, hydrostatic and breaker test equipment. Westinghouse has made significant investments in equipment and skilled resources to perform a wide variety of commercial grade dedication qualification testing.

  • Westinghouse uses its own triaxial table with the latest testing software for seismic testing and analysis.
  • Westinghouse has a number of environmental chambers allowing for a variety of test conditions.
  • Westinghouse's state-of-the-art electromagnetic compatibility (EMC) chambers provide the means to ensure components & systems meet all industry EMC requirements.

With a team of more than 75 qualified inspectors, technicians and engineers experienced in executing CGD activities, Westinghouse dedicates hundreds of components per month, from fuses and bolts to circuit breakers and electrical cabinets.
