Power plant life extension involves extending the operational lifespan of existing power plants beyond their original design life, aiming to maximize electricity generation and resource utilization while ensuring safety and environmental compliance.
How is Power Plant Life Extension Achieved?
Renovation and Modernization (R&M) : This involves upgrading and improving existing power plant components and systems to enhance performance and extend their lifespan.
Plant Life Management (PLiM) : This is a comprehensive approach that integrates aging management, maintenance planning, periodic safety reviews, and training to ensure safe and reliable operation throughout the extended lifespan.
Non-Destructive Testing (NDT) : NDT methods, such as ultrasonic testing and eddy current testing, are used to assess the condition of critical components and identify potential issues before they lead to failures.
Material Degradation Assessment : Evaluating the extent of material degradation, including corrosion, embrittlement, and creep, is crucial for determining the remaining lifespan of components.
Component Replacement : Some components, like steam generators in nuclear plants, may need to be replaced during the life extension process to ensure continued safe and reliable operation.
