v. PECO Energy Company, Docket No. R-00038102, adopted September 5,2003 2) Letter from J. McNulty (Pennsylvania Public Utility Commission) to B. D. Crowe (Philadelphia Electric Company), "Pennsylvania Public Utility Commission

v. PECO Energy Company," dated December 31,2007 In accordance with 10 CFR 50.75, "Reporting and recordkeeping for decommissioning planning," paragraph (f)(l), we are submitting a report on the status of decommissioning funding for the reactors owned by Exelon Generation Company, LLC (EGC) and AmerGen Energy Company, LLC (AmerGen).

March 28,2008 U. S. Nuclear Regulatory Commission Page 2 Attachment 1 contains the amount of decommissioning funds estimated to be required for the permanently shutdown reactors based on site-specific decommissioning cost estimates.

These decommissioning cost estimates do not include the costs of dismantling non-radiological systems and structures or the costs of managing and storing spent fuel on-site. Attachment 2 contains the amount of decommissioning funding accumulated through December 31, 2007. Attachment 3 contains a schedule of annual amounts to be collected through the final year as indicated. Additional information regarding assumptions used for decommissioning cost escalation rates and trust fund earnings rates, and the method of providing financial assurance is included below. With respect to each of the above units, there are no contracts relied upon pursuant to 10 CFR 50.75(e)(l)(v), nor have there been any material changes to the trust agreements. Additional information regarding assumptions used for decommissioning cost escalation rates and trust fund earnings rates and the method of providing financial assurance is included below. For Dresden Nuclear Power Station and Oyster Creek Nuclear Generating Station, a 2.0% annual real rate of return is being assumed on the decommissioning trust funds. Financial assurance for decommissioning continues to be provided by the prepayment method, coupled with an external trust fund, in accordance with 10 CFR 50.75(e)(l)(i).

For Peach Bottom Atomic Power Station, Unit 1, the rate of escalation assumed in decommissioning costs is approximately 3.5% (gross domestic product deflator) and the rate of earnings assumed for the decommissioning funds is 6.5% (Reference 1). As documented in Reference 2, the Pennsylvania Public Utility Commission approved a revision to the annual amount to be collected for Peach Bottom Atomic Power Station, Unit 1, to $2.280 million to reflect changes in the estimated cost of decommissioning and in the period of collection. Financial assurance for decommissioning this reactor is provided by the external sinking fund method in accordance with 10 CFR 50.75(e)(l)(ii).

The funding mechanism being used as the source of revenues for the external sinking fund is a "non-by-passable charge." There are no regulatory commitments contained within this letter.
