NRC TO DISCUSS THREE MILE ISLAND 1 NUCLEAR PLANT ASSESSMENT 

AT PUBLIC MEETING SCHEDULED FOR APRIL 3 IN MIDDLETOWN, PA. 

The results of the Nuclear Regulatory Commission’s annual safety performance 

assessment for the Three Mile Island Unit 1 nuclear power plant will be discussed at a public 

meeting on Thursday, April 3. The session is scheduled to begin at 7 p.m. at Londonderry Town 

Hall, 738 S. Geyers Church Road in Middletown, Pa. 

Three Mile Island 1 is a pressurized-water reactor located in Middletown (Dauphin 

County) and operated by AmerGen Energy Co., LLC. 

Prior to the conclusion of the meeting, NRC staff will be available to answer questions 

from the public on the plant’s performance, as well as the agency’s oversight of the facility. 

“Through a combination of inspection findings and performance indicators, we are able 

to develop a comprehensive picture of how nuclear power plants are performing with regard to 

safety,” said NRC Region I Administrator Samuel J. Collins. “As part of our commitment to 

make the findings of our reviews accessible to the public, we hold meetings near each plant once 

a year to share the details of those assessments. We look forward to the opportunity on April 3rd

to present that information for the Three Mile Island 1 nuclear power plant.” 

The annual assessment letter for Three Mile Island 1 is available on the NRC web site at:

the meeting, with agenda attached, is available in the NRC’s Agencywide Documents Access

Overall, the Three Mile Island 1 plant operated safely during 2007. When considering 

nuclear power plant performance, the NRC uses color-coded performance indicators and

inspection findings. The colors start with “green” and then increase to “white,” “yellow” or 

“red,” commensurate with the safety significance of the issues involved. 

At the conclusion of last year, there were no performance indicators for Three Mile 

Island 1 that were other than “green” and no inspection findings that were “greater than green.” 

Therefore, the plant will receive the baseline, or routine, level of inspections for the remainder of 

2008. 

Routine inspections are carried out by the two NRC Resident Inspectors assigned to the 

plant and by inspection specialists from the agency’s Region I Office in King of Prussia, Pa. 

Among the areas of performance at Three Mile Island 1 to be inspected this year by NRC 

specialists are activities associated with radiological protection, fire protection, and problem 

identification and resolution. 

Separately, NRC reviews associated with a license renewal application for the plant will 

continue throughout 2008. The application, which seeks a 20-year extension of the facility’s 

operating license, was submitted in January of this year. 

Current performance information for Three Mile Island 1 is available on the NRC web 

site at: http://www.nrc.gov/NRR/OVERSIGHT/ASSESS/TMI1/tmi1_chart.html .
