The Three Mile Island Nuclear Station, Unit 1 is a pressurized-water reactor located 10 miles southeast of Harrisburg, Pa. The current operating license expires April 19, 2014. Exelon Generation Group, LLC, owner and operator (formerly Amergen Energy Company, LLC.), submitted an application to the NRC on Jan. 8, 2008, to extend the TMI-1 license by 20 years. Under NRC regulations, the original operating license for a nuclear power plant has a term of 40 years. The license may be renewed for up to an additional 20 years if NRC requirements are met. Therefore if approved, the current operating license for TMI-1, which expires on April 19, 2014, would be extended until 2034.

The SER documents the results of the NRC staff’s review of the license renewal application and site audits of plant’s aging management programs to address the safety of plant operations during the period of extended operation. Overall, the results show that the applicant has identified actions that have been or will be taken to manage the effects of aging in the appropriate safety systems, structures and components of the plant and that their functions will be maintained during the period of extended operation.

The NRC’s independent Advisory Committee on Reactor Safeguards (ACRS) will evaluate the SER and make its recommendation before the agency makes a final decision on the renewal of the license. The ACRS will hold a meeting that is open to public participation. The meetings will take place at NRC Headquarters in Rockville, Md. on Sept. 10. The meeting will be announced on the agency’s Web site at http://www.nrc.gov/public-involve/public-meetings/index.cfm. Afterwards, the ACRS will issue a report discussing the results of its review.

A copy of the SER will be available in the NRC’s Agencywide Documents Access and Management Systems (ADAMS) under accession number ML091660470. ADAMS is accessible via the agency’s Web site at: http://www.nrc.gov/reading-rm/adams.html. Help in using ADAMS is available by contacting the NRC’s Public Document Room at 1-800-397-4209 or 301-415-4737, or by e-mail at pdr.resource@nrc.gov.
