Proposed Zion License Transfer

Pat, We have some financial questions, provided below, regarding the transfer. Please let me know if any of the questions are unclear.

The staff has noted Exelon's submittal RS-08-041, dated March 28, 2008, which provided the report on status of decommissioning funding for reactors. In that report the amount of decommissioning funds estimated to be required for Zion Unit 1 is $310.2 million and for Zion Unit 2 is $309.9 million. These totals, which do not include the cost of dismantling non-radiological systems and structures or the cost of managing and storing spent fuel on-site, are less than the totals provided in Enclosure 6 of the January 25, 2008, application. provides an estimate of $714.0 million, excluding spent fuel storage and site restoration.

Although spent fuel storage is excluded from both estimates, RS-08-041 also excludes dismantling non-radiological systems and structures, and Enclosure 6 of the January 25, 2008, application also excludes site restoration. Is site restoration included in RS-08-041 or just not delineated? Is dismantling non-radiological systems and structures included in the estimate provided in Enclosure 6 of the January 25, 2008, application?

If so, why?

Please clarify what is included in the line item Spent Fuel Storage. Does this include construction and loading of the ISFSI, long term maintenance, and/or any other aspects?

Please address any other differences between the RS-08-041 and Enclosure 6 estimates, in particular any differences not related to the change in methodology?

Please clarify if the entire estimate of $714.0 million provided in Enclosure 6 of the January 25, 2008, application reflects the expenses and associated funds to radiologically decontaminate the Zion Facilities to NRC standards. If not please provide a revised estimate that separates expenses and funding for NRC required decommissioning activities from other decommissioning activities.

Thanks, John Tracking:
