摘　　要：早期核电厂的设计中,主要从经济角度确定设计寿命。实际运行经验表明,核电厂到设计寿命时,主体仍可安全运行。为进一步确定核电厂寿期内及延寿后的安全性,开展了老化管理工作。电仪设备的老化评估筛选是老化管理的重要组成部分。通过对重要度、老化的敏感度和难易度3项指标的综合评分,筛选出需进一步老化研究和管理的设备清单,以保证在满足安全性的同时,经济合理地开展老化研究和管理工作。The design life of the NPPs is calculated in economic terms, based on return on investment. However, many plants can be safely operated after reaching the life time. In order to ensure the safety of the NPPs during and after their life, the Systematic ageing management is carried out worldwide. The screening of Electrical and IC equipments for ageing evaluating is part of the ageing management. According to the importance,Sensitivity and easy to ageing, the list of the equipments which are needed to do the ageing management is got. Such the ageing research and management can be developed in an economic way, and also ensure the safety of the plant.
