Status of License Renewal

11

NRC License Renewal

• Original License Term – 40 years

• 10 CFR Part 54, License Renewal Rule

• Renewed License Term – +20 years for each renewal(i.e., 40 years, 60 years, 80 years, . . .)

• Application for renewal – after 20 years of operation butat least 5 years before expiration of current license

• Three main review areas by NRC: safety, environmental,and adjudicatory

SummarySafety, performance, cost, environmental, and public opinionfactors are favorable for operation of U.S. nuclear power plants formore than 60 years

Continued investment in refurbishments and upgrades required tomaintain the trend of safety, reliability, and performanceimprovements

Existing NRC regulatory structure for LR and SLR ensures safe andenvironmentally responsible long term operation of U.S. nuclearpower plants

Continuous improvement of aging management activities must bemaintained based on lessons learned and operating experience –effective corrective action programs

Research and development efforts by EPRI, DOE, NRC, and othersare essential to support and maintain the option of long termoperation and SLR
