Goodwin ITT Industries, an instrument vendor, notified the NRC that an inappropriate bonding process was used in the manufacture of an IEEE I/P transducer, causing it to not conform with test and performance requirements of standards IEEE 323, "Qualifying Class 1E Equipment for Nuclear Power Generating Stations," and IEEE 344, "Recommended Practice for Seismic Qualification of Class 1E Equipment for Nuclear Power Generating Stations." The transducer would potentially not perform its intended safety function during a seismic event involving high radiation or high temperature steam. Product model numbers involved are: GT25CA1826 GT45CA1826 GT65CA1826 GT25FA1826 GT45FA1826 GT65FA1826 Domestic nuclear power utilities that may be affected include Duke Energy, Commonwealth Edison, New York Power Authority, Northeast Nuclear Energy, Omaha Public Power District, Alabama Power, Detroit Edison, and GPU Nuclear. The vendor expects to conclude its analysis by December 15, 2000, and to make replacement units available by February 15, 2001. The NRC will post ensuing reports on this subject on its website at http://www.nrc.gov/NRC/PUBLIC/PART21/2000. _
