This report defines and encourages the use of a set of common terms and definitions that characterize aging and aging management of nuclear power plant systems, structures, and components. Common aging terminology encompasses the areas of degradation causes, degradation/aging, life, failure, and maintenance. The terminology should prove useful in plant license renewal, life-cycle management, maintenance, and equipment qualification. The principal intended benefits are improved reporting and interpretation of plant experience data (especially failure data) and improved interpretation and compliance with codes, standards, and regulations related to aging of nuclear power plants. The terminology was developed using a sound, systematic technical and lexicographical approach, as well as input from a committee with members from electric utilities, the Nuclear Management and Resources Council (NUMARC), the Electric Power Research Institute (EPRI), the United States Nuclear Regulatory Commission (NRC), and national research laboratories. Draft definitions received an extensive industry review. Formal comments were received from 19 organizations worldwide. The report presents the results of this effort and contains definitions, figures, examples of usage, dictionary definitions, and discussions describing the relationships among the 85 terms and 27 synonyms of the common aging terminology. The terms and definitions are generally consistent with similar terminology used by the Institute of Nuclear Power Operations (INPO). The common aging terminology has been reviewed by NUMARC and the NRC and is recommended for use throughout the nuclear power industry.
