Entergy Response to NRC Request for Additional Information to Support the Review of the Pilgrim Nuclear Power Station Spent Fuel Management Plan Pursuant to 10 CFR 50.54(bb) and the Preliminary Decommissioning Cost Estimate Pursuant to 10 CFR 50.75(f)(3)(TAC NOS.

Kim, Project Manager Plant Licensing Branch I-1 Division of Operator Reactor Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission One White Flint North O-8C2 11555 Rockville Pike Rockville, MD 20852 Regional Administrator, Region 1 U.S. Nuclear Regulator Commission 475 Allendale Road King of Prussia, PA 19406 Senior Resident Inspector Pilgrim Nuclear Power Station Attachment 1 to Letter 2.08.052 Entergy Response to NRC Request for Additional Information to Support the Review of the Pilgrim Nuclear Power Station Spent Fuel Management Plan Pursuant to 10 CFR 50.54(bb) and the Preliminary Decommissioning Cost Estimate Pursuant to 10 CFR 50.75(f)(3) (TAC NOS. MD8036 and MD9416)(5 Pages)208052 Entergy Response to NRC Request for Additional Information to Support the Review of the Pilgrim Nuclear Power Station Spent Fuel Management Plan Pursuant to 10 CFR 50.54(bb) and the Preliminary Decommissioning Cost Estimate Pursuant to 10 CFR 50.75(f)(3) (TAC NOS. MD8036 and MD9416)/Spent Fuel Management Program (SFMP) and Preliminary Decommissioning Cost Estimate (PDCE)NRC RAI No. 1: Section 5 of the SFMP, Financial Assurance and Section 1.7.1 of the PDCE, Spent FuelDisposition Pilgrim stated in both Section 5 of the SFMP and in Section 1.71. of the PDCE, the cost associated with the isolation and continued operation of the spent fuel pool, and the construction and operation of the Independent Spent Fuel Storage Installation (ISFSI)would be covered by the decommissioning trust funds. The costs are identified in Table 5 and included in the decommissioning cost estimate in Table 8 of PDCE.Withdrawals from decommissioning trust funds under 10 CFR 50.82(a)(8)(i)(A) are limited to legitimate decommissioning activities consistent with the definition of decommissioning.
In addition, withdrawals under 10 CFR 50.82(a)(8)(i)(C) are not permitted if they would inhibit the ability of the licensee to complete funding of any shortfalls in the decommissioning trust needed to ensure the availability of funds to ultimately release the site and terminate the license. For the scenario that was indentified in Pilgrim's submittal, Pilgrim did acknowledge in their discussion the necessity for an exemption in accordance with 10 CFR 50.12, from the requirements of 10 CFR 50.82(a)(8)(i)(A) in order to use the decommissioning trust funds for spent fuel management expenses.
What is the source of funds to address the annual spent fuel costs identified in Table 5 of the PDCE?Entergy Response: Pilgrim Nuclear Power Station (PNPS) Spent Fuel Management plan assumes withdrawals from the decommissioning trust for spent fuel management purposes.Entergy will make appropriate submittals for an exemption in accordance with 10 CFR §50.12.from the requirements of 10 CFR §50.82(a)(8)(i)(A) in order to use the decommissioning trust funds for spent fuel management expenses.Entergy will also monitor the decommissioning fund to ensure that spent fuel management withdrawals will not inhibit the ability of Entergy to complete'radiological decommissioning.
It should be noted that the projected expenditures for spent fuel management identified in the preliminary decommissioning cost analysis do not include any credit or offset for costs that may be incurred by the licensee, Entergy Nuclear Operations, Inc. (ENO), as a result of the Department of Energy's (DOE) failure in the timely removal of spent fuel from the site pursuant to the DOE contractual obligations (Nuclear Waste Policy Act).ENO believes that the extended spent fuel management costs are compensable damages incurred by ENO that should be paid by DOE because DOE failed to comply with the contractual obligations for the disposal of spent fuel for the site. This would provide an alternate source of funds for spent fuel management, and as such, the results of litigation or potential changes in future government policy could reduce or eliminate the need to make withdrawals from the trust fund for spent fuel management.
However, the analysis for the Spent Fuel Management Program conservatively assumes that these costs are not recovered from DOE.280052 Page 1of 5 Entergy Response to NRC Request for Additional Information to Support the Review of the Pilgrim Nuclear Power Station Spent Fuel Management Plan Pursuant to 10 CFR 50.54(bb) and the Preliminary Decommissioning Cost Estimate Pursuant to 10 CFR 50.75(f)(3) (TAC NOS. MD8036 and MD9416)Preliminary Decommissioning Cost Estimate (PDCE)NRC RAI No. 2: Section 2.2 Financial Assurance of the PDCE In Section 2.2, Pilgrim stated that their analysis, whose results are shown in Table 8 of the July 31, 2008, submittal, was based on a 3-percent inflation rate. Was the 3-percent inflation rate based on the information identified in Section 2.1, "Escalation of the 2005 Costs to 2007 Dollars" or was it based on a different analysis?
Based on the information provided in Section 2.1, the NRC staff could not reproduce the 3-percent inflation rate.Pilgrim should provide the supporting analysis that was used to develop the 3-percent escalation rate.Entergy Response: A 3% inflation rate (along with a 5% earnings rate) has been used by the licensee in the past to escalate the estimated decommissioning cost in the 10 CFR 50.75(f)(1) reports on the status of the decommissioning funding for the Pilgrim Nuclear Power Station (Reference 4). It was used in the Table 8 analyses for consistency with the assumptions in the 50.75(f)(1) reports for future escalation of decommissioning costs.280052 Page 2 of 5 Entergy Response to NRC Request for Additional Information to Support the Review of the Pilgrim Nuclear Power Station Spent Fuel Management Plan Pursuant to 10 CFR 50.54(bb) and the Preliminary Decommissioning Cost Estimate Pursuant to 10 CFR 50.75(f)(3) (TAC NOS. MD8036 and MD9416)NRC RAI No. 3: Section 2.2 Financial Assurance of the PDCE Section 2.2 stated that Pilgrim used a 1.47 percent real rate of return to produce the results listed in Table 8. The staff applied both the Pilgrim's 1.47 percent real rate of return as well as a 2 percent real rate of return. The staff analysis was based on a trust balance of $621.76 million and a license termination date of 2012 and deducted the expenses identified in Table 7, "Pilgrim Nuclear Power Station Schedule of Annual Expenditures, License Termination and Spent Fuel Management Allocations." The staff analysis did not support the conclusion that sufficient funds would be available to decommission Pilgrim starting in 2043 applying the licensee's real rate of return of 1.47 percent. In addition, the staff could not reconcile the differences between Pilgrim's and the staff's approaches for analyzing the decommissioning trust fund balance and projected expenditures.
The licensee should provide the supporting analysis for values/cost identified in each of the columns listed in Table 8.Entergy Response: The original Table 8 displays the results of a present value method which solved for the required rate of return necessary to end up with a net zero balance for the trust fund at the completion of decommissioning.
The analysis showed a real rate of return less than 2% would be required for this scenario.However, a more basic method that the licensee believes is acceptable to the Staff is to escalate the trust fund balance of $621.74 million assuming a 2% rate of return and compare the earnings against the costs shown in Table 7 for license termination and spent fuel. As shown in the attached Revised Table 8; this results in a positive balance at the conclusion of decommissioning, confirming that there/ are more than sufficient funds for both activities (radiological and spent fuel). The licensee requests that the Staff substitute the Revised Table 8 in the licensee's plan for the original Table 8. The calculation methodology for Revised Table 8 is shown at the end of the table.(Using the values of 3% inflation and 4.47% in the attached table, the decommissioning trust fund would net to $0 at the conclusion of the decommissioning process, consistent with the analysis previously provided in the original Table 8.)280052 Page 3 of 5 Entergy Response to NRC Request for Additional Information to Support the Review of the Pilgrim Nuclear Power Station Spent Fuel Management Plan Pursuant to 10 CFR 50.54(bb) and the Preliminary Decommissioning Cost Estimate Pursuant to 10 CFR 50.75(f)(3) (TAC NOS.MD8036 and MD9416)Pilgrim Nuclear Station Decommissioning Funding Plan (thousands of 2007 dollars)Table 8 (Revised)Basis Year 2007 Fund Balance $621.740 (millions)
