Reactor License Renewal Orientation
All commercial nuclear power reactors operating in the United States must be licensed and monitored by the NRC. The original license issued by the NRC is limited to 40 years. If a reactor operator seeks to extend its original license, it must submit an application to the NRC for an independent evaluation of the safety and environmental issues related to license renewal.
On this page:
What Is License Renewal?
The license renewal review provides an independent examination, asking the following questions:
- Does the reactor operator understand the effects of aging on critical safety components?
- Has the operator taken appropriate actions to assure safe operation?
For additional information, see How Did the License Renewal Process Develop?
How Does the Reactor License Renewal Process Work?
If a reactor operator seeks to extend its original license, it must submit an application to the NRC that
- Identifies any reactor system, structure and component that would be affected by license renewal.
- Demonstrates that it can safely manage the adverse effects of aging during the renewal period.
For additional information, see What Is a Safety Review?
- Analyzes the environmental effects of extended reactor operation.
For additional information, see What Are the Requirements for an Environmental Review?
How Long Does a License Renewal Last?
The current operating license allows a nuclear power plant to operate for 40 years. The licenses are renewable. 10 CFR Part 54 allows a new license to be issued to operate for up to 20 years beyond the current term.
For additional information, see Why 40 Years?
What Are the Principles of License Renewal?
There are two principles of license renewal:
- The regulatory process is adequate to ensure the safety of all currently operating plants, with the possible exception of the detrimental effects of aging.
- Plant specific licensing basis must be maintained during the renewal term in the same manner and to the same extent as during the original licensing term.
For additional information, see The Principles of License Renewal.
What Are the License Renewal Regulations?
The license renewal review process proceeds along two parallel paths: One is a safety review, which evaluates whether the plant can continue to operate safely during the period of extended operation. The other is an environmental review, which evaluates the interaction between the plant and the surrounding environment.
- Safety Review (10 CFR Part 54)
- Safety Evaluation
- Advisory Committee on Reactor Safeguards review
- Inspection Verification
- Environmental Review (10 CFR Part 51)
- National Environmental Policy Act (NEPA)

Opportunities for Public Participation
There are ways that the public can be heard:
- Public outreach information meeting
- Hearing Opportunities and License Applications
For additional information, see Hearing
- Public meetings on environmental scoping
- Opportunity to provide environmental scoping comments
- Public meetings on the draft environmental impact statement
- Opportunity to provide comments on the draft environmental impact statement
- ACRS meetings
- Public meetings on safety review, including inspection and audit exit meetings
License Renewal Schedule
The license renewal process schedule goal is
- 22 month schedule (if there is no hearing), or
- 30 month schedule with hearing
NRC monitors efforts to identify process improvements.
For additional information, see Scheduling.
