2011 Report on Status of Decommissioning Funding for Reactors

Reference:

Letter from Patrick R. Simpson (Exelon Generation Company, LLC) to U. S. NRC, "Parent Guarantees for Decommissioning Financial Assurance,"

dated August 9, 2010 Pursuant to 10 CFR 50.75, "Reporting and recordkeeping for decommissioning planning,"

paragraph (f)(1), Exelon Generation Company, LLC (EGC) is submitting a report on the status of decommissioning funding for the reactors owned by EGC.

In accordance with 10 CFR 50.75(b), the minimum required decommissioning funding assurance amounts are based either on the NRC minimum formula per 10 CFR 50.75(c), or on site-specific decommissioning cost estimates. Site-specific decommissioning cost estimates used are based on a period of safe storage that is specifically described in the estimates. The decommissioning cost estimates do not include the costs of dismantling non-radiological systems and structures or the costs of managing and storing spent fuel onsite.

EGC has not made the final determination of the decommissioning approach for any of its nuclear units. The generic and site-specific calculations have been selected to demonstrate adequacy of funding to meet NRC requirements. EGC may select a different decommissioning option in the future for any of its nuclear units, recognizing that the chosen option must meet NRC requirements for decommissioning funding.

As documented in the Reference, Exelon Corporation previously established parent guarantees to provide additional decommissioning funding assurance for the following units owned by EGC:

Braidwood Station, Unit 1 - $69M Braidwood Station, Unit 2 - $63M Byron Station, Unit 2 - $87M

March 31,2011 U. S. Nuclear Regulatory Commission Page 3 Based on the data as of December 31, 2010, adequate decommissioning funding assurance is provided for these three units, without taking credit for any additional funding assurance provided by these parent guarantees. Therefore, the parent guarantees are no longer required. Hence, this letter also serves as notice to the NRC that Exelon Corporation intends to cancel these parent guarantees. This cancellation will not occur until 120 days after the date of this notice, as specified by 10 CFR 30, Appendix A.

There were no disbursements from these trust funds other than those for allowed administrative costs and other incidental expenses of the fund in connection with the operation of the fund in accordance with 10 CFR 50.75(h)(1)(iv).

There are no regulatory commitments contained within this letter.

If you have any questions about this letter, please contact me at (630) 657-2823.
