November 23,2010 U.S. Nuclear Regulatory Commission ATTN : Document Control Desk Washington, DC 20555-0001 Zion Nuclear Power Station (ZNPS), Units 1 and 2 Facility Operating License Nos. DPR-39 and DPR-48 NRC Docket Nos. 50-295 and 50-304

Subject:

Notification of a Significant Schedule Change from that Provided in the Amended Post-Shutdown Decommissioning Activities Report (PSDAR)

Reference:

(1) Letter from Patrick Daly, Zion Solutions, LLC to NRC, "Notification of Amended Post-Shutdown Decommissioning Activities Report (PSDAR) for Zion Nuclear Power Station, Units 1 and 2 in Accordance with 10 CFR 50 .82(a)(7)", dated March 18,2008 This letter provides notification of a significant change to the Zion Nuclear Power Station (ZNPS) decommissioning schedule that was provided in Reference 1 as part of the "Amended Post-Shutdown Activities Report (PSDAR)." The schedule is being updated in accordance with 10 CFR 50.82(a)(7) to reflect the two-year delay in the start of the project which is associated with fluctuations in the value of the ZNPS decommissioning trust funds that began in 2008.

The amended PSDAR submitted by the Reference 1 letter included a decommissioning schedule based on the then current schedule expectations for completion of the transfer of the ZNPS assets and the NRC operating licenses from Exelon Generation Company, LLC (EGC) to ZionSolutions, LLC in the second half of calendar year 2008. This attached schedule reflects current projections based upon the actual transfer of the assets and licenses on September 1, 2010. The overall project duration is essentially the same as that provided in the amended PSDAR, approximately 10 years. The sequence, timing and duration of some major activities have undergone some refinement as the project planning has achieved more detail. No significant, adverse impacts to either overall duration or total estimated costs have occurred.
