NRC TO HOLD PUBLIC MEETING ON MAY 18th IN LIMERICK, PA.,

TO DISCUSS ANNUAL ASSESSMENT OF LIMERICK NUCLEAR POWER PLANT

 Nuclear Regulatory Commission staff will hold a public meeting on Wednesday, May 18, 

regarding the agency’s annual assessment of safety performance for the Limerick nuclear power 

plant during 2010.

The meeting is scheduled to begin at 6 p.m. at the Limerick Township Building, at 646 

W. Ridge Pike in Limerick, Pa. Prior to the session’s conclusion, there will be an opportunity for 

members of the public to ask questions of the NRC staff regarding the plant’s performance, as 

well as the agency’s oversight of the facility.

Limerick is the site of two boiling-water reactors. It is located in Limerick Township 

(Montgomery County), Pa., and is owned and operated by Exelon Generation Co., LLC.

“Our Annual Assessment reviews allow us to step back and gauge whether the nuclear 

power plants we regulate are on the right track in terms of performance and adhering to the 

highest levels of safety,” NRC Region I Administrator Bill Dean said. “Once we’ve completed 

these evaluations, we reach out to the public to share that information and to receive their 

feedback at a location near each plant. We welcome and value these exchanges.”

The NRC utilizes a combination of color-coded inspection findings and performance 

indicators to measure plant performance. The colors start with “green”, representing very low 

safety significance, and increase to “white”, “yellow” or “red”, commensurate with the 

significance of the issues involved.

Overall, the Limerick 1 and 2 reactors operated safely during 2010. At the conclusion of 

last year, as assessed through the NRC’s Reactor Oversight Process, there were no inspection

findings that were “Greater than Green” (rising to the level requiring additional NRC oversight) 

or any performance indicators that were other than “Green” (exceeding the threshold for the 

indicator and requiring additional NRC oversight) for the units. Therefore, for the remainder of 

2011, Limerick will continue to receive the very detailed inspection regime used by the NRC for 

plants that are operating well.

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

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

2010, the NRC devoted about 5,900 hours to inspection of Limerick, including four major team 

inspections. Among the areas at Limerick being inspected this year are the dry cask storage of 

spent fuel, radiological safety, permanent plant modifications and emergency preparedness.

The agency issues its review of performance at specific plants twice a year. Inspection 

findings and performance indicators are also updated on the NRC’s website, www.nrc.gov, each 

quarter. Following the release of the annual performance reviews every March, the public is 

provided with an opportunity to discuss the results. The meetings, which are held in the vicinity

of the plant, are in keeping with the NRC’s commitment to transparency and openness with 

regard to its activities.

The annual assessment letter for Limerick 1 and 2 is available on the NRC website at:

http://www.nrc.gov/NRR/OVERSIGHT/ASSESS/LETTERS/lim_2010q4.pdf. The notice for the 

public meeting is available in the NRC’s Agencywide Documents Access and
