Applications of License Renewal Evaluation Methodology to Identify Key Components for Generic Life Assessment.

摘要

The review and evaluation of plant equipment for nuclear power plant license renewal differ from the initial licensing of the plant. A substantial operating history has been established, the licensing basis has evolved from the original one, and plant equipment has been subject to periodic maintenance and surveillance throughout its life. With the sponsorship of the Department of Energy and under the auspices of the Nuclear Management and Resources Council (NUMARC) Nuclear Utilities Plant Life Extension (NUPLEX) Working Group, the industry has developed a systematic approach to identify and evaluate plant equipment for license renewal. The approach focuses the review and evaluation on those safety-significant systems and components subject to age-related degradation that are not subject to recognized effective replacement, refurbishment, or inspection programs. 1 fig., 2 tabs.
