摘要

摘要: 基于对安全级电气设备（1E设备）鉴定方法和鉴定寿命的分析和研究，将分析再评估技术应用于核电厂有环境鉴定要求的电缆（EQ电缆）的寿命评估，可在满足安全要求的前提下合理地延长EQ电缆的鉴定寿命，确保电缆在鉴定寿命的延长期内仍然能够按照规范的要求实现其预期功能。该方法不仅可用于核电厂正常运行期间电缆合格鉴定状态的评估，也可用于电缆在核电厂运行许可证延续（OLE）期间实现其预期功能的能力评估，该方法在国内核电厂已有实际应用。

Abstract: Based on the analysis and study of the qualification method and qualified life of safety grade electrical equipment (1E equipment), the analysis and re-evaluation technology is applied to the life assessment of the cable (EQ cable) with environmental qualification requirements in nuclear power plant, which can reasonably extend the qualified life of EQ cable on the premise of meeting the safety requirements, and ensure that the cable can still achieve its expected function according to the requirements of the specification during the extended period of qualified life. This method can be used not only to evaluate the qualification status of cables during normal operation of power plants, but also to evaluate the ability of cables to achieve their expected functions during the Operation License Extension (OLE) of nuclear power plants. This method has been applied in domestic nuclear power plants.
