摘要

ANSI/ANS-3.14-2021, Process for Infrastructure Aging Management and Life Extension of Nonreactor Nuclear Facilities (new standard). This standard addresses requirements for systematically evaluating structures, systems, and components (SSCs) for extending the life of non-reactor nuclear facilities. This standard provides a systematic process to determine the scope of the aging management/life extension program in terms of SSCs. For those SSCs, a process for the evaluation of remaining lifetime and determining the need for additional analysis, repairs, inspections, surveillance, testing, and spare part obsolescence will be developed.
