UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 June 28, 2012 Mr. Michael J. Pacilio President and Chief Nuclear Officer Exelon Generation Company, LLC 4300 Winfield Road Warrenville, IL 60555
SUBJECT:
LIMERICK GENERATING STATION, UNIT NO.1 - STATUS OF DECOMMISSIONING FUNDING ASSURANCE (TAC NO. ME8248)
Dear Mr. Pacilio:
By letter dated March 31,2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML110980080), Exelon Generation Company, LLC (Exelon, the licensee) submitted to the U.S. Nuclear Regulatory Commission (NRC) the 2011 Decommissioning Funding Status (DFS) report for Limerick Generating Station (LGS), Unit 1, as required under Title 10 of the Code ofFederal Regulations (10 CFR) Section 50.75, "Reporting and recordkeeping for decommissioning planning." This letter reflected funding considerations as of December 31, 2010. On July 27, 2011 (ADAMS Accession No. ML112092312), Exelon submitted supplemental information in response to a request for additional information (RAI) from the NRC staff regarding the status of the decommissioning funds. Subsequently, by letter dated January 11,2012 (ADAMS Accession No. ML113540721), based on an NRC-calculated shortfall as of December 31, 2010, the NRC requested further information from Exelon.
Specifically, the NRC requested that Exelon provide its most current plan to meet the NRC's financial assurance requirements for LGS, Unit 1. On February 23, 2012 (ADAMS Accession No. ML12054A256), Exelon provided a response to this second RAt. In that letter, Exelon provided its plan, the current decommissioning trust fund amount, and the minimum funding according to the calculation in 10 CFR 50.75(c), as of December 31,2011.
In a letter dated March 27, 2012 (ADAMS Accession No. ML120720382), the NRC staff informed Exelon it had closed out its review of the 2011 DFS report for LGS, Unit 1 (Le., decommissioning information as of December 31,2010). The letter also stated that the NRC staff would continue its review of the decommissioning information provided as of December 31, 2011, for LGS, Unit 1, in order to determine there was reasonable assurance that funds will be available for the decommissioning process.
On April 20, 2012 (ADAMS Accession No. ML121080344), the NRC staff requested additional information from Exelon regarding its submittal dated February 23, 2012. Exelon provided its response to this RAI in a letter dated May 21, 2012 (ADAMS Accession No. ML121420477).
Using the information provided in Exelon's letters dated February 23, and May 21,2012, the NRC staff performed an analysis, equivalent to a DFS report analysis, to determine if the plan of action provided decommissioning funding assurance. The reported amount of decommissioning funds estimated to be required by the formula in 10 CFR 50.75(c) by Exelon was $660.4 million and independently determined by the NRC staff to be $639.1 million. In the May 21, 2012, letter, you stated that the certification amount that must be covered by your financial assurance method is $639.1 million.
M. Pacilio
- 2 Based on the reported decommissioning trust balance as of December 31,2011, the earnings credit specified under NRC regulations, the parent company guarantee and your filing with the Pennsylvania Public Utilities Commission for a proposed cost adjustment to the collection of annual payments from ratepayers, the NRC determined that the amount of decommissioning financial assurance you provided based on your plan of action was equal to or greater than the minimum required amount based on 10 CFR 50.75(c). As such, the NRC staff concludes that there is reasonable assurance that funds will be available for the decommissioning process for LGS, Unit 1. The NRC staffs DFS report analysis is enclosed.
If you have any questions, please contact me at (301) 415-1420.
Sincerely,
-tJS~
