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.
