NRC ISSUES FINAL ENVIRONMENTAL IMPACT STATEMENT FOR 

THREE MILE ISLAND NUCLEAR PLANT LICENSE RENEWAL APPLICATION 

 

 The Nuclear Regulatory Commission staff has issued its final supplemental safety 

environmental impact statement (SEIS) for the proposed renewal of the operating license for the 

Three Mile Island Nuclear Station, Unit 1 (TMI-1), located in Middletown, Pa. The report 

concluded there are no environmental impacts that would preclude license renewal for an 

additional 20 years of operation. 

 TMI-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 would be extended until 2034. 

 As part of its environmental review of the application, the NRC held public meetings 

near the plant to discuss the review process and the draft version of the environmental impact 

statement. Comments were received and considered from members of the public, local officials, 

and representatives of state and federal agencies. 

 Publication of the final environmental impact statement does not represent final NRC 

action on the license renewal application. The agency staff has completed its safety evaluation 

report that will be evaluated by the NRC’s Advisory Committee on Reactor Safeguards (ACRS) 

in September. The ACRS will make its recommendation to the Commission before the agency 

makes a final decision. 

 The TMI-1 final environmental impact statement is available on the NRC’s Web site at: 

http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr1437/supplement37/ and can also 

be viewed in the NRC’s ADAMS online documents system at http://www.nrc.gov/readingrm/adams/web-based.html by entering accession number “ML091751063” in the search 

window.
