Life extension vs Life Management
3
Plant Life Management Output
• Critical SSCs (safety and power production)
• Provides a decision analysis tool and methodology that prioritizes and allocates the plant resources
• Provides financially optimized long-term aging and obsolescence management plans f
• Identifies and mitigates risks associated with components
• Identifies aging effects that can lead to reduced reliability and unexpected degradation to availability.

Source: Nuclear Energy Institute
15 units would have been shutdown by end of 2012 without license renewal! 100 nuclear units
produce ~20% of U.S. capacity
At June 2013, the NRC had extended the licences of 73 reactors (72
still operating). The NRC is considering licence renewal
applications for 18 further units, with 7 more applications expected.
