Abstract

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.
- Environmentally qualified cable (EQ cable),
- Qualified life,
- Harsh environment,
- Mild environment.
