本标准提供了标准和指南，以系统地评估结构、系统和组件的剩余寿命，并确定是否需要进行额外的分析和检查，以解决老化管理问题，以支持延长非反应器核设施（NRNFs）的寿命。本标准适用于NRNFs，包括核材料加工和储存设施、燃料制造和浓缩设施或转换/解转换设施等设施。

This standard provides criteria and guidance to systematically evaluate structures, systems, and components for remaining lifetime and determine the need for additional analysis and inspection to address aging management in support of extending the life of nonreactor nuclear facilities (NRNFs).This standard applies to NRNFs including facilities such as nuclear material processing and storage facilities as well as fuel fabrication and enrichment facilities or conversion/deconversion facilities.
